Here, we report a colloidal hot-injection synthesis of ternary cesium copper selenide (CsCu5Se3) nanocrystals (NCs), achieving precise control over phase, size, and morphology through tailored precursor-ligand modulation. This strategy enabled systematic exploration of stable and metastable Cs–Cu–Se phases and mechanistic investigation of nucleation and growth, providing insight into phase modulation and dimensional control at the nanoscale. CsCu5Se3 NCs exhibit low lattice thermal conductivity (∼0.5 Wm–1K–1) and an experimental zT of 0.27 at 718 K. Complementary first-principles calculations, consistent with experimental electronic and optical responses, predict a zT of 1.05 at 1000 K. These findings elucidate the formation dynamics of CsCu5Se3 and establish ABZ (A = alkali, B = metal, Z = chalcogen) NCs as tunable platforms for advanced functional applications. acknowledgement: This publication has emanated from research conducted with the financial support of Taighde Éireann-Research Ireland under Grant number 22/FFP-P/11591.

Argyrodite-type Ag8SnSe6 exhibits a melt-like Ag sublattice that drives lattice thermal conductivity (κL) below 0.2 watts per meter per kelvin, yet its low carrier concentration limits the power factor. Here, interstitial Ag atoms raise the Fermi level into the conduction band, substantially increasing the electron concentration. Simultaneously, the formation of a secondary Ag2Se phase generates lattice distortions that enhance phonon scattering. A pronounced mismatch between electronic (~200 nanometers) and phononic (~0.22 nanometers) mean free paths decouples charge and heat transport, enabling concurrent suppression of κL and retention of high electrical conductivity. This coupled electronic-phononic modulation yields a record ZT of 0.72 at ambient temperature and a peak ZT of 1.1 at 735 kelvins, with an average ZTavg of 0.72 over 320 to 735 kelvins. A unicouple device achieves 6.3% efficiency under a 357-kelvin gradient, highlighting a practical strategy for high-performance midtemperature thermoelectrics. acknowledged_ssus: - _id: LifeSc acknowledgement: The Scientific Service Units (SSU) of ISTA supported this research through resources provided by the Lab Support Facility (LSF).

This strategy strongly depends on the thermodynamics and kinetics between the solid booster and dissolved redox species. Conventional electrochemical methods often convolute intrinsic reactivity with mass transport effects, introducing complexity in determining limiting steps. We propose a strategy that confines solid boosters within recessed microelectrodes and employs scanning electrochemical microscopy (SECM) to estimate reaction kinetics between booster and dissolved active redox species. Confining the solid booster in the recessed microelectrode overcomes mass transport limitations of dissolved redox species and enables controlled polarization of the booster material, allowing deconvolution of key rate-determining factors. As an initial model system, Prussian blue-ferricyanide/ferrocyanide [Fe(CN)6]3−/4− was used as solid booster and dissolved redox active species, respectively. The methodology was further explored for copper hexacyanoferrate with N,N,N-2,2,6,6-heptamethylpiperidinyl oxy-4-ammonium chloride and nickel hydroxide with [Fe(CN)6]3−/4− and extended to Mn-based Prussian blue analogues in combination with organic redox species. Our results demonstrate that SECM coupled with the proposed recessed microelectrode strategy provides a powerful platform to disentangle interfacial kinetics and guide the rational design of solid booster-dissolved redox species and electrolytes for high-performance redox-mediated flow batteries. acknowledgement: "The authors acknowledge funding from the European Union's Horizon Europe research and innovation programme— European Innovation Council (EIC) under the grant agreement No 101046742 (MeBattery).

However, it suffers from poor cycle life associated with the rock-salt phase transformation. This study presents a straightforward synthesis approach to enhance the electrochemical performance of LiNi0.5Mn1.5O4 through a synergistic solid-state modification with LiF and AlF3. This dual modification promotes rapid Li⁺ diffusion, enables near-complete delithiation/lithiation, approaching the theoretical capacity of disordered LiNi0.5Mn1.5O4, and, more importantly, effectively mitigates the formation of the rock-salt phase, thereby enhancing structural stability, as confirmed by operando X-ray absorption spectroscopy (XAS) and synchrotron X-ray diffraction (SXRD). As a result, the optimized LiNi0.5Mn1.5O4 (10 mg AlF3 + 30 mg LiF) delivers high reversible capacities of 142.1, 139.1, 129.2, 121.6, 110.3, 93.5, and 76.1 mAh∙g−1 at 0.2C, 0.5C, 1.0C, 2.0C, 3.0C, 4.0C, and 5.0C, respectively. Full cells using graphite as the anode and a high-loading cathode exhibit excellent cycling performance. They retain 80% of their capacity after 200 cycles at 0.5C within a voltage window of 3.5–4.9 V with cathode loading of 11 mg∙cm−2. The findings of this study will significantly advance high-power LiNi0.5Mn1.5O4 materials, offering improved battery life and thereby enhancing their potential for practical applications. acknowledged_ssus: - _id: EM-Fac - _id: NanoFab acknowledgement: 'This work was supported by the European Commission-financed project IntelLigent (HORIZON-CL5-2021-D2-01-02) with project ID number 101069765.

Herein, we report a ligand-free aqueous synthesis of Te-doped CuAgSe (CuAgSe1-xTex), where structural and electronic modulation improve carrier transport and suppress phonon propagation. Ex-situ time-resolved X-ray diffraction reveals a spontaneous growth mechanism, while density functional theory calculations show that Te-5s and 5p orbitals hybridization generates localized states and an asymmetric density of states, thereby enhancing the Seebeck coefficient. Electron microscopy and strain analyses confirm that Te-doping introduces a high density of lattice dislocations and grain boundaries, leading to a reduced lattice thermal conductivity of 0.11 W m−1K−1 at 443 K. These synergistic effects translate into device-level performance—the first integrated CuAgSe thermoelectric modules, exhibit a maximum cooling temperature difference of 27.3 K, and power density of 0.34 W cm−2 with a conversion efficiency of 3.6% at a modest temperature gradient of 136 K. These results demonstrate that CuAgSe1-xTex enables efficient energy harvesting and localized cooling under small temperature gradient, underscoring the importance of structural and electronic design beyond conventional zT benchmarks. acknowledgement: K.H.L. acknowledges financial support from the National Natural Science Foundation of China (NSFC) (Grant Number 22208293) and the National Foreign Expert Project (Y20240175).

In this study, FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S) reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells, and pouch cells reveal that HEANS significantly enhance LSB performance, achieving initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent cycling stability over 1000 cycles at 3Cand maintain high-rate performance up to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density functional theory calculations demonstrate that amorphous HEANS provide more active sites, better ionic conductivity and stronger chemical interactions with lithium polysulfides (LiPS). These properties effectively suppress the shuttle effect, promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy barrier. Overall, this study highlights the superior catalytic properties of amorphous 2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion. acknowledged_ssus: - _id: EM-Fac acknowledgement: The authors acknowledge support from the 2BoSS project of the ERA-MIN3 program with the Spanish grant number PCI2022-132985/AEI/10.13039/50110001103, and funding from Generalitat de Catalunya 2021SGR01581 and European Union NextGenerationEU/PRTR.

Here, we report a simple strategy for synthesizing a palladium-based heterostructured electrocatalyst supported on a carbon nitride matrix (PdH-Pd@CN), which exhibits remarkable ORR activity with a half-wave potential of 0.91 V and excellent durability in 0.1 M KOH. Within the heterostructure, hydrogen intercalation expands the Pd lattice, while interstitial hydrogen doping facilitates charge transfer from Pd to H owing to their electronegativity difference. These synergistic effects modulate the electronic structure, thereby enhancing both activity and stability. When employed in Zn-air batteries, PdH-Pd@CN delivers a maximum power density of 176 mW cm− (Liu et al., 2025) and capacity of 805 mAh g− (Sun et al., 2021) Zn. These findings demonstrate the strong potential of PdH-Pd@CN as an efficient ORR electrocatalyst for next-generation metal-air batteries and related energy technologies. acknowledged_ssus: - _id: EM-Fac - _id: NanoFab acknowledgement: The authors thank the support from the National Natural Science Foundation of China (NSFC) (Grants No. 22302151) and Natural Science Foundation of Hubei Province (Grants No. 2024AFB755, 2024AFB267), Key Project of Hubei Provincial Department of Education Scientific Research Plan (F2023007).

This study presents a detailed comparative analysis of three strategies to promote the electrical transport properties of Cu3SbSe4 through Sn doping: conventional Sn atomic doping, surface treatment with SnSe molecular complexes, and blending with SnSe nanocrystals to form nanocomposites, all followed by annealing and hot pressing under identical conditions. Our results reveal that a surface treatment using SnSe molecular complexes significantly enhances TE performance over atomic doping and nanocomposite formation, achieving a power factor of 1.1 mW·m−1·K−2 and a maximum dimensionless figure of merit zT value of 0.80 at 640 K, representing an excellent performance among Cu3SbSe4-based materials produced via solution-processing methods. This work highlights the effectiveness of surface engineering in optimizing the transport properties of nanostructured materials, demonstrating the versatility and cost-efficiency of solution-based technologies in the development of advanced nanostructured materials for application in the field of TE among others.' acknowledgement: Y.

Characterization techniques, including thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD), elucidated a plausible reaction pathway for the formation of phase-pure BFO NPs. Rietveld refinement of the XRD data, in conjunction with transmission electron microscopy (TEM) and Raman spectroscopy, confirmed the synthesis of single-phase BFO NPs at 400 °C, displaying a space group of R3c and an average crystallite size of 25 nm. UV–visible diffuse reflectance spectroscopy revealed an absorption cut-off wavelength near 590 nm, corresponding to a band gap of 2.08 eV, indicating the capability of BFO NPs to absorb visible light within the 400–590 nm range. BFO NPs have shown efficient and rapid photocatalytic degradation of methylene blue (MB) in acidic, neutral, and basic pH conditions under natural sunlight. This is attributed to the intrinsic ferroelectric and ferromagnetic ordering present in synthesized BFO NPs which facilitates the separation and migration of photoinduced charges through band bending phenomena at the interface. acknowledgement: "Simant Kumar Srivastav greatly acknowledges the University Grant Commission (UGC), New Delhi, India for providing BSR start-up grant to carry out this research work.\r\nThis research was supported by start-up grant of the University Grant Commission (UGC), New Delhi, India through project no F-30-500/2019 (BSR)." article_processing_charge: No article_type: original author: - first_name: Madhu full_name: Verma, Madhu last_name: Verma - first_name: Ajay full_name: Kumar, Ajay last_name: Kumar - first_name: Vijay Kumar full_name: Thakur, Vijay Kumar last_name: Thakur - first_name: Akanksha full_name: Maurya, Akanksha last_name: Maurya - first_name: Sachin full_name: Kumar, Sachin last_name: Kumar - first_name: Saurabh full_name: Singh, Saurabh id: 12d625da-9cb3-11ed-9667-af09d37d3f0a last_name: Singh orcid: 0000-0003-2209-5269 - first_name: Simant Kumar full_name: Srivastav, Simant Kumar last_name: Srivastav citation: ama: Verma M, Kumar A, Thakur VK, et al.

However, its practical application is hindered by inherently high lattice thermal conductivity and low electrical conductivity. In this study, we address these challenges by surface functionalization of PbS nanocrystals using Cu2S molecular complexes-based ligand displacement. The molecular complexes facilitate the incorporation of Cu into the PbS matrix and leads to the formation of nanoscale defects, dislocations, and strain fields while optimizing the charge carrier transport. The structural modulations enhance the phonon scattering and lead to a significant reduction in lattice thermal conductivity of 0.60 W m−1K−1 at 867 K in the PbS-Cu2S system. Simultaneously, the Cu incorporation improves electrical conductivity by increasing both carrier concentration and mobility with carefully optimized the content of Cu2S molecular complexes. These synergistic modifications yield a peak figure-of-merit (zT) of 1.05 at 867 K for the PbS-1.0 %Cu2S sample, representing an almost twofold enhancement in TE performance compared to pristine PbS. This work highlights the effectiveness of surface treatment in overcoming the intrinsic limitations of PbS-based materials and presents a promising strategy for the development of high-efficiency TE systems. acknowledgement: Y.L. acknowledges funding from the National Natural Science Foundation of China (NSFC) (Grants No. 22209034), the Innovation and Entrepreneurship Project of Overseas Returnees in Anhui Province (Grant No. 2022LCX002) and the Fundamental Research Funds for the Central Universities (JZ2024HGTB0239).

Herein, we investigate how Zn(CF3COO)2 additives influence solvation structure and elucidate the mechanism by which these additives promote the dual reduction of anions. Through cryo-transmission electron microscopy analysis, we identified the SEI as a highly amorphous ZnS/ZnF2 phase. This amorphous hybrid SEI demonstrates exceptional stability, mechanical robustness, and high Zn2+ conductivity, effectively mitigating parasitic reactions and enhancing Zn plating/stripping reversibility. Even under elevated current densities, the Zn anode exhibits ultra-stable longevity and ultra-high reversibility. This study provides a comprehensive understanding of the intrinsic mechanisms governing solvation structure modulation that lead to the formation of amorphous hybrid SEI, underscoring their efficacy in enhancing the performance and durability of AZIBs. acknowledged_ssus: - _id: EM-Fac - _id: NanoFab acknowledgement: The authors acknowledge financial support from the Joint Fund of Henan Province Science and Technology R&D Program (235200810097) and the Generalitat de Catalunya (2021SGR01581).

Thereby, by harnessing temperature differences in vitro or in vivo, TE nanomaterials can provide antimicrobial reactive oxygen species (ROS) by catalyzing redox reactions, thereby accelerating wound healing by suppressing infection. However, despite their promising potential, there is still a lack of comprehensive understanding of the antimicrobial mechanisms, biocompatibility, and practical applications of TE nanomaterials in wound healing, as this is a newly-emerged sub-area of energy-related biomedical applications. This review aims to address this gap by highlighting the emerging progress of TE materials in wound healing, clarifying their mechanism and advances, emphasizing their potential challenges for commercialization and clinical use, and proposing novel design strategies of TE nanomaterials for effective antibacterial performance. acknowledgement: This work was financially supported by the Sichuan Science and Technology Program (Nos. 2023ZYD0064 and 2023YFG0220), the Fundamental Research Funds for the Central Universities (No. YJ202242), and the Research Funding from West China School/Hospital of Stomatology, Sichuan University (No. QDJF2022–2). article_processing_charge: No article_type: review author: - first_name: Shiyu full_name: Jia, Shiyu last_name: Jia - first_name: Cai full_name: Qi, Cai last_name: Qi - first_name: Shengduo full_name: Xu, Shengduo id: 12ab8624-4c8a-11ec-9e11-e1ac2438f22f last_name: Xu - first_name: Lei full_name: Yang, Lei last_name: Yang - first_name: Qiang full_name: Sun, Qiang last_name: Sun citation: ama: Jia S, Qi C, Xu S, Yang L, Sun Q.

However, macroscopic electrodes and related analytical techniques show challenges concerning the number of additional influencing parameters. We explore recessed microelectrodes (rME) as a platform that allows for a binder-free investigation of Prussian Blue analogues (PBA), a family of promising battery materials. The enhanced diffusion using microelectrochemical tools is indispensable to assess the intrinsic material performance, overcoming the limitation of cation diffusion from the electrolyte to the solid interface during (dis)charging cycles and allowing the investigation of limiting steps in the coupled ion-electron transfer process. The intrinsic electrochemical performance of PBAs was studied in a three-electrode configuration by means of cyclic voltammetry and galvanostatic (dis)charging in aqueous Na+-containing electrolyte. We extended the evaluation to the role of the electrolyte on the performance of cathodic and anodic processes of a Mn-based PBA. Ex-situ and operando chemical characterization were coupled to support the microelectrochemical results. acknowledgement: The authors acknowledge funding from the European Union's Horizon Europe research and innovation programme – European Innovation Council (EIC) under the grant agreement 101046742 (MeBattery), the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (CasCat [833408]), and the Spanish Government (Ministerio de Ciencia e Innovación, Grants PID2021-124974OB-C22).

Among these, Ag8SnSe6 stands out for its exceptionally low sound velocity and thermal conductivity. However, the inherent poor electrical conductivity and suboptimal thermoelectric properties of Ag8SnSe6 necessitate further improvement. Here, a novel approach is initiated to enhance the thermoelectric properties of Ag8SnSe6 by combining low-dimensionalization with intrinsic doping. For the first time, this work successfully synthesizes single-phase Ag8SnSe6 nanocrystals, ≈10 nm in size, with the correct phase and composition using a robust and reliable colloidal method. This approach represents a significant improvement over previous reports on this material. Reducing the crystal domains of Ag8SnSe6 to the nanoscale induces quantum confinement effects, increasing the density of states near the Fermi surface. It also introduces additional grain boundaries, which lower the lattice thermal conductivity and simplify structural design. Moreover, incorporating small amounts of Sn nanopowder into the Ag8SnSe6 nanocrystals before consolidation further enhances the thermoelectric performance. Sn acts as a donor dopant, increasing the electronic concentration while at the same time improving their mobility by reducing interface barriers, thus significantly improving the material transport properties. Additionally, the presence of Sn leads to the formation of point defects, dislocations, and secondary phases, which increase phonon scattering and further reduce the thermal conductivity. Through this synergistic optimization, the figure of merit shows a significant increase across a wide temperature range. Overall, a strategy is presented for the controlled preparation of Ag8SnSe6 nanocrystals, the decoupling of their electrical and thermal transport, and the practical application of this material to thermoelectric single-leg modules. acknowledgement: X.Z. and M.L. contributed equally to this work.

This platform combines a coplanar-gated field-effect transistor (FET) architecture with grating-coupled surface plasmon resonance (SPR), yielding an integrated disposable sensor chip prepared by nanoimprint and maskless photolithography techniques. The sensor chip design is suitable for scalable production and relies on reduced graphene oxide (rGO), serving as the FET’s semiconductor material for the electronic readout, and a metallic gate electrode surface that is corrugated with a multi-diffractive structure for optical probing with resonantly excited surface plasmons. Together with its integration in a compact instrumentation this results in a form factor optimized solution for dual-mode investigations without compromising the optical or electronic sensor performance. A poly-L-lysine (PLL) – based thin linker layer was deployed at the sensor surface to covalently attach azide-conjugated biomolecules by using incorporated “clickable” dibenzocyclooctyne (DBCO) moieties. Interestingly, the dual-mode measurements allow elucidating the role of the globular nature of the PLL chains when increasing the density of DBCO attached to their backbone, leading to PLL folding and internalization of DBCO moieties, and thus reducing the coupling yield for the used DNA oligomers. We envision that this platform can be employed to studying a range of other biointerface architectures and biomolecular interaction phenomena, which are inherently tied to mass and charge density variations. acknowledged_ssus: - _id: EM-Fac acknowledgement: We thank the Electron Microscopy Facility at ISTA for their support with sputter coating the FO probes and NOSI GmbH for their support with 3D printing. article_processing_charge: Yes (in subscription journal) article_type: original author: - first_name: Roger full_name: Hasler, Roger last_name: Hasler - first_name: Pietro A. full_name: Livio, Pietro A. last_name: Livio - first_name: Anil full_name: Bozdogan, Anil last_name: Bozdogan - first_name: Stefan full_name: Fossati, Stefan last_name: Fossati - first_name: Simone full_name: Hageneder, Simone last_name: Hageneder - first_name: Verónica full_name: Montes-García, Verónica last_name: Montes-García - first_name: Jacopo full_name: Movilli, Jacopo last_name: Movilli - first_name: Taghi full_name: Moazzenzade, Taghi last_name: Moazzenzade - first_name: Luna full_name: Loohuis, Luna last_name: Loohuis - first_name: Ciril full_name: Reiner-Rozman, Ciril last_name: Reiner-Rozman - first_name: Adrián full_name: Tamayo, Adrián last_name: Tamayo - first_name: Christine full_name: Fiedler, Christine id: bd3fceba-dc74-11ea-a0a7-c17f71817366 last_name: Fiedler - first_name: Maria full_name: Ibáñez, Maria id: 43C61214-F248-11E8-B48F-1D18A9856A87 last_name: Ibáñez orcid: 0000-0001-5013-2843 - first_name: Christoph full_name: Kleber, Christoph last_name: Kleber - first_name: Jurriaan full_name: Huskens, Jurriaan last_name: Huskens - first_name: Jakub full_name: Dostalek, Jakub last_name: Dostalek - first_name: Paolo full_name: Samorì, Paolo last_name: Samorì - first_name: Wolfgang full_name: Knoll, Wolfgang last_name: Knoll citation: ama: Hasler R, Livio PA, Bozdogan A, et al.

In this work, we design and fabricate a simple Ag2Se nanofilm-based TE biosensor to precisely quantify hydrogen peroxide (H2O2) levels in liquid samples. A chemical reaction involving horseradish peroxidase, ABTS and H2O2 in the specimens produces a photothermal agent—ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) free radical, which triggers the heat fluctuations at the TE sensor through the photo-thermal effect, eventually enabling the sensing of H2O2. Consequently, the constructed sensor can achieve a detection limit of 0.26 μM by a three-leg TE device design. Further investigations suggest that the application of our TE sensor can be extended in testing H2O2 in beverages (including milk, soda water, and lemonade) and evaluating the load of bacterial pathogens relevant to dental diseases and infections including Streptococcus sanguinis and Methicillin-resistant Staphylococcus aureus with high analytical accuracy. This strategy utilizes the combination of high thermoelectric performance with chemical reactions to realize a straightforward and accurate biomarker detection method, making it suitable for applications in medical diagnostics, personalized health monitoring, and the food industry. acknowledgement: This work was supported by the Sichuan Science and Technology Program (Grant No. 2023YFG0220, 2023ZYD0064, and 2024YFHZ0309) and the Fundamental Research Funds for the Central Universities and Research Funding from West China School/Hospital of Stomatology Sichuan University, No. QDJF2022-2. article_processing_charge: No article_type: original author: - first_name: Huangshui full_name: Ma, Huangshui last_name: Ma - first_name: Shiyu full_name: Pu, Shiyu last_name: Pu - first_name: Shiyu full_name: Jia, Shiyu last_name: Jia - first_name: Shengduo full_name: Xu, Shengduo id: 12ab8624-4c8a-11ec-9e11-e1ac2438f22f last_name: Xu - first_name: Qiwei full_name: Yu, Qiwei last_name: Yu - first_name: Lei full_name: Yang, Lei last_name: Yang - first_name: Hao full_name: Wu, Hao last_name: Wu - first_name: Qiang full_name: Sun, Qiang last_name: Sun citation: ama: Ma H, Pu S, Jia S, et al.

We address these challenges by using an extrusion-based 3D printing technique to fabricate high-performance thermoelectric materials. Our ink formulations ensure the integrity of the 3D-printed structure and effective particle bonding during sintering, achieving record-high figure of merit (zT) values of 1.42 for p-type bismuth antimony telluride [(Bi,Sb)2Te3] and 1.3 for n-type silver selenide (Ag2Se) materials at room temperature. The resulting TEC demonstrates a cooling temperature gradient of 50°C in air. Moreover, this scalable and cost-effective method circumvents energy-intensive and time-consuming steps, such as ingot preparation and subsequently machining processes, offering a transformative solution for thermoelectric device production and heralding a new era of efficient and sustainable thermoelectric technologies. acknowledged_ssus: - _id: EM-Fac - _id: LifeSc - _id: M-Shop - _id: NanoFab acknowledgement: This work was supported by the Scientific Service Units (SSU) of ISTA through resources provided by the Electron Microscopy Facility (EMF), the Lab Support Facility (LSF), the Communication & Events facility, the Miba Machine Shop, and the Nanofabrication Facility (NNF).

This work completes the study of the RNi6Si6 series (R = rare earth). While the RNi6Si6 compounds for R = La and Ce adopt the CeNi6Si6-type (tP52, P4/nbm, No. 125), surprisingly PrNi6Si6 crystallizes in the YNi6Si6 prototype (tP52, P − 4b2, No. 117) as do all the heavier lanthanides (but Lu). The YNi6Si6-type and its homolog CeNi6Si6 are two tetragonal ordered derivative of the cubic NaZn13-type structure. Lattice parameters for PrNi6Si6 are a = 7.7846(1) Å, c = 11.2144(1) Å, with a unit cell volume, Vobs = 679.585(5) Å3. The temperature dependence of the inverse magnetic susceptibility χ−1(T) follows the Curie–Weiss law, with calculated values of the effective magnetic moment (µeff) and Weiss temperature (Θpm) of 3.55 μB and − 4.5 K, respectively. While the observed µeff is very close to the theoretical value of 3.58 µB for the free Pr3+ ions, a negative value of the Weiss temperature suggests antiferromagnetic interactions in PrNi6Si6. Magnetization measurements confirm that PrNi₆Si₆ orders antiferromagnetically (AFM) below a Néel temperature (TN) of 9 K. The Ni atoms contribute negligibly to the magnetic properties of this phase. The specific heat of PrNi₆Si₆ is approximately 0.42 J K  − 1  g − 1. Measurements of electric and thermal transport reveal that PrNi₆Si₆ exhibits metallic behavior across a wide temperature range of 2–900 K, accompanied by a relatively low thermal conductivity of around 6 W K − 1 m − 1 at room temperature. Such properties, together with its high-temperature refractory behavior, make PrNi₆Si₆ worthy of consideration in technological applications where fairly good electrical conductivity should be accompanied by a limited thermal conductivity. article_number: '100051' article_processing_charge: No article_type: original author: - first_name: Saurabh full_name: Singh, Saurabh id: 12d625da-9cb3-11ed-9667-af09d37d3f0a last_name: Singh orcid: 0000-0003-2209-5269 - first_name: A. full_name: Provino, A. last_name: Provino - first_name: I. full_name: Pallecchi, I. last_name: Pallecchi - first_name: F. full_name: Caglieris, F. last_name: Caglieris - first_name: M. full_name: Mödlinger, M. last_name: Mödlinger - first_name: P. full_name: Mele, P. last_name: Mele - first_name: G. full_name: Latronico, G. last_name: Latronico - first_name: T. full_name: Takeuchi, T. last_name: Takeuchi - first_name: P. full_name: Manfrinetti, P. last_name: Manfrinetti citation: ama: 'Singh S, Provino A, Pallecchi I, et al.
