text: Tissue tension is a key determinant of tissue shape, and its regulation is
essential for both morphogenesis and the maintenance of tissue integrity. During
zebrafish embryogenesis, the enveloping layer (EVL) – an epithelial monolayer
covering the blastoderm – undergoes extensive spreading that is driven by pulling
forces exerted at its margin and more than doubles its surface area. Yet whether
and how the EVL actively regulates its tissue tension during this process remains
unclear. Here, we show that the EVL maintains constant tissue tension while spreading,
and that it achieves this by reducing apical cell contractility in response to
the same pulling forces that drive its spreading. We identify a mechanosensitive
pathway underlying this response, mediated by the scaffold/adaptor protein Kibra
regulating the activity of atypical protein kinase C (aPKC) at the apical domain
of EVL cells. Under low mechanical stretch, Kibra forms condensates at the base
of actin-based apical projections, where it activates Myosin II to increase apical
contractility through aPKC downregulation. As mechanical stretch increases, apical
projections disassemble, Kibra condensates dissolve, and aPKC activity rises.
Elevated aPKC activity in turn reduces apical contractility by reducing Myosin
II activity, thereby maintaining constant tissue tension despite increased mechanical
stretch. Together, these findings reveal a mechanosensitive mechanism that enables
robust adaptation of tissue tension to changing mechanical stretch, ensuring efficient
tissue spreading and morphogenesis.

text: RNA polymerase II (Pol II) must be assembled in the cytoplasm before it enters
the nucleus, where it transcribes protein-coding genes. Although transcription
by Pol II is intensively studied, how this central multi-subunit enzyme is made
and the role of dedicated assembly factors remains unclear. Here, we report the
integrative structural analysis of a native human Pol II from the cytoplasm captured
near the end of biogenesis. The complex contains Gdown1 and three biogenesis factors
– RPAP2 and the critical small GTPases GPN1 and GPN3. Cryo-EM analysis of the
complex reveals how Gdown1 and RPAP2 associate with Pol II and prevent the premature
association of transcription factors. Further biochemical and cryo-EM analysis
reveals how RPAP2 tethers GPN1–GPN3 to the complex and how the assembly of the
RPAP2–GPN1–GPN3 complex is controlled by GTP hydrolysis. The combined results
uncover a network of interactions that chaperone cytoplasmic Pol II to prevent
aberrant interactions, reveal a molecular switch regulating biogenesis factor
association, and suggest a general mechanism for the action of GPN-loop GTPase
family of enzymes.

text: High-voltage disordered spinel LiNi0.5Mn1.5O4 is a promising cathode material
for high power density in lithium-ion batteries. 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.

text: High-entropy alloys (HEAs) show great potential for catalyzing complex multi-step
reactions, but optimizing their parameters, i.e., composition, but also their
crystallinity and morphology, remains a significant challenge. 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.

text: The oxygen reduction reaction (ORR) remains a critical bottleneck in fuel
cells and metal-air batteries due to the lack of highly efficient electrocatalysts.
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.

text: 'Swimming bacteria move through a fluid by actuating their moving body parts.
They are force-free and can be described as hydrodynamic force dipoles: pushers
or pullers. This modelling description is broadly used in biological physics and
active matter research, and it has successfully predicted, for example, the superfluid
behaviour of suspensions of pushers or the bend instability and emergence of turbulent
flows in active nematics. However, this description accounts only for the translational
motion of the swimming body and neglects the effects of hydrodynamic torque dipoles,
which are relevant to bacteria with rotary motor-driven flagella, such as swimming
Escherichia coli. Here we show that the torque dipole of confined swimming E.
coli can power the persistent rotation of symmetric discs. The torque dipole leads
to a traction force on the discs, an additive mechanism that is both contactless
and independent of the orientation of the bacteria. Our results indicate that
the torque dipole of swimming E. coli is notable in confined geometries, which
is relevant to bacterial transport through porous materials, biofilms and the
development of chiral fluids.'

text: For tissues to spread, they must deform while staying intact. How spreading
tissues balance flexibility with integrity is not yet well understood. Here, we
show that keratin intermediate filaments adapt tissue mechanical resilience to
the stresses arising in epithelial tissues during spreading. By analyzing the
expansion of the enveloping cell layer (EVL) over the yolk cell in zebrafish embryos
in vivo, we find that keratin network maturation in EVL cells is promoted by stresses
building up within the spreading tissue. Through genetic interference and tissue
rheology experiments, complemented by a vertex model with mechanochemical feedback,
we demonstrate that stress-induced keratin network maturation in the EVL increases
tissue viscosity, to prevent tissue rupture. Further, keratins are required in
the yolk cell for mechanosensitive actomyosin network contraction and flow, the
forces pulling the EVL. These dual mechanosensitive functions of keratins enable
a balance between pulling force production and EVL mechanical resilience, ensuring
uniform and robust tissue spreading.

text: Nanocrystal superlattices are commonly formed by changing concentration, solvent
conditions, or particle surface chemistry. Although effective, these approaches
alter multiple contributions to the interparticle potential simultaneously, making
it difficult to isolate the interactions responsible for ordering or to control
assembly in chemically complex environments. Here, we show that oligomeric species
present in a nanocrystal reaction medium drive superlattice formation through
a depletion mechanism. Using PbTe nanocrystals as a model system, we identify
Pb–oleate oligomers in the crude reaction mixture, characterize their solution
structure, and quantify their contribution to the interparticle potential, establishing
depletion as the dominant short-range interaction governing spontaneous body-centered
cubic superlattice formation. We then confirm the depletion origin of ordering
by showing that varying depletant concentration predictably shifts the order–disorder
boundary and produces a thermally reversible transition between dispersed and
ordered states ─ behavior that is inconsistent with van der Waals or ligand-mediated
mechanisms but is a direct consequence of depletion control. Having established
and validated the mechanism, we demonstrate that the same depletion framework
can be deliberately activated in purified dispersions and transferred across nanocrystal
systems of different composition and shape, including anisotropic and binary assemblies.
These results establish precursor-derived depletion as a general and chemically
grounded mechanism for nanocrystal superlattice formation, and show that collective
ordering can be programmed through the surrounding medium rather than through
particle surface modification.

text: 'How the twin-arginine translocase (Tat) system transports fully folded substrate
proteins across cellular membranes without disrupting membrane integrity has been
a fundamental question in cell biology for decades. The Tat system, found in prokaryotes
and plant organelles, recognizes a cargo signal peptide via a conserved twin-arginine
motif. The multi-subunit Tat complex facilitates the proton-motive-force-dependent
translocation process, yet its overall architecture has remained unknown. Here,
we present the cryo-electron microscopy (cryo-EM) structure of the Escherichia
coli (E. coli) trimeric TatB₃C₃ complex with bound substrate SufI, assembled in
vivo. The complex adopts an unusual, wide-open, bowl-shaped architecture with
a polar inner cavity. Unexpectedly, the cargo is engaged in a dual-contact mode:
while the signal peptide binds inside one TatBC unit, the folded domain docks
tightly onto an adjacent unit, possibly performing a proofreading function. This
structure provides a mechanistic framework for substrate engagement and suggests
the direct involvement of the entire Tat complex in substrate translocation.'

text: Silver selenide (Ag2Se) is a promising near-room-temperature thermoelectric
material, but its narrow stoichiometric window and β–α phase transition complicate
reproducible microstructure control. Here, we present a mismatch-assisted microstructure
engineering strategy in which Ag2Se particles are treated with polyanionic ZnSe
complexes and consolidated through the β–α transition to introduce ZnSe nanoprecipitates,
Ag2Se/ZnSe interfaces, and local strain fields. The crystallographic mismatch
between ZnSe and Ag2Se, together with the Zn2+/Ag+ size difference, amplifies
phase-transition-induced deformation and promotes high-density dislocations with
periodic strain modulations. This defect architecture suppresses grain coarsening,
removes excess Ag, limits Ag-interstitial formation, and reduces lattice thermal
conductivity through lattice softening and multiscale phonon scattering. Ag2Se–4%ZnSe
nanocomposites achieve a peak zTmax of 1.13 at 369 K and a zTavg of 1.08 from
300 to 380 K, demonstrating mismatch-driven defect engineering through the β–α
phase transition as a route for optimizing Ag2Se-based thermoelectrics.

text: "Contact electrification (CE) is a simple yet elusive phenomenon that occurs
when two materials come into contact and separate, leaving behind net electrical
charge. Despite its ubiquity, the microscopic origin of CE remains unclear. In
this thesis, we investigate CE from three complementary perspectives: developing
a quantitative method to measure charge at the nanoscale, exploring the dynamic
behavior of charge on insulating surfaces, and uncovering the role of mechanical
history in forming a triboelectric series.\r\n\r\nIn the first part, we establish
a rigorous framework for converting qualitative Kelvin probe force microscopy
(KPFM) voltage maps into quantitative charge density distributions. Using finite
element method (FEM) simulations, we determine the point-spread function of the
KPFM tip–sample geometry and demonstrate that the true surface charge can be reconstructed
by numerical deconvolution. This procedure enables the recovery of both the magnitude
and sign of charge density with high fidelity, resolving nanoscale features that
are otherwise obscured. Applying the method to contact-charged SiO$_2$ surfaces,
we show that existing analytical approximations, such as parallel plate or spherical
models, can miscalculate charge magnitude by orders of magnitude. Our hybrid FEM/KPFM
approach therefore provides a fast and general method to convert qualitative KPFM
signals into quantitative charge data, enabling nanoscale charge mapping under
realistic experimental conditions.\r\n\r\nIn the second part, we study the temporal
stability of CE-induced charges and identify the key material factors that determine
whether KPFM can capture meaningful charge patterns. Through time-resolved experiments
combining a custom-built transfer system with both microscopic and macroscopic
measurements, we demonstrate that only the best insulators, such as SiO$_2$, preserve
CE charge long enough for stationary imaging. For less conductive polymers, such
as PDMS, charge decays within the duration of a single KPFM scan due to bulk conduction.
Using a simple capacitor-based model, we reproduce the observed decay dynamics
and confirm that the transferred charge decays characteristic to the sample's
bulk conductivity. Further, we always observe homogeneous charge transfer.\r\n\r\nIn
the third part, we address the question: can we form a triboelectric series with
identical materials? Using controlled repetitive contact experiments, we show
that nominally identical materials can progressively order themselves into a triboelectric
series, where surfaces with more contact history charge negatively relative to
fresher ones. By constructing a minimal model based on this ``contact bias'',
we replicate the evolution from random to ordered charging observed in experiments.
Supporting surface analyses, including atomic force microscopy, reveal that repeated
contact induces nanoscale morphological changes, suggesting a mechanism tightly
coupled to mechanical strain. These results highlight the crucial role of surface
history and nanoscale mechanics in dictating charge transfer, motivating further
exploration of mechanisms such as mechanochemical bond cleavage and flexoelectric
polarization."

text: Bacteria, like eukaryotes, use conserved cytoskeletal systems for intracellular
organization. The plasmid-encoded ParMRC system forms actin-like filaments that
segregate low–copy number plasmids. In multicellular cyanobacteria such as Anabaena
sp., we found that a chromosomally encoded ParMR system has evolved into a cytoskeletal
system named CorMR with a function in cell shape control rather than DNA segregation.
Live-cell imaging, in vitro reconstitution, and cryo–electron microscopy revealed
that CorM formed dynamically unstable, antiparallel double-stranded filaments
that were recruited to the membrane by CorR through an amphipathic helix conserved
in multicellular cyanobacteria. CorMR filaments were regulated by MinC, which
excluded them from the poles and division plane. Comparative genomics indicated
that the repurposing of ParMR and Min systems coevolved with cyanobacterial multicellularity,
highlighting the evolutionary plasticity of cytoskeletal systems in bacteria.

text: Transcription by RNA polymerase II (Pol II) can be repressed by noncoding
RNA, including the human RNA Alu. However, the mechanism by which endogenous RNAs
repress transcription remains unclear. Here we present cryogenic-electron microscopy
structures of Pol II bound to Alu RNA, which reveal that Alu RNA mimics how DNA
and RNA bind to Pol II during transcription elongation. Further, we show how distinct
domains of the general transcription factor TFIIF control repressive activity.
Together, we reveal how a noncoding RNA can regulate mammalian gene expression.

text: Electrolyte additives are extensively validated effective in mitigating dendrite
growth and parasitic reactions in aqueous zinc-ion batteries (AZIBs). Nonetheless,
the mechanisms by which additives influence the formation and characteristics
of the inorganic solid–electrolyte interphase (SEI) are not yet fully elucidated.
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.

text: We present a novel, portable sensor platform that enables concurrent monitoring
of surface mass and charge density variations at thin biointerfaces. 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.

text: Thermoelectric coolers (TECs) are pivotal in modern heat management but face
limitations in efficiency and manufacturing scalability. 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.

text: The SiOx anode exhibits a high specific capacity and commendable durability
for lithium-ion batteries (LIBs). However, its practical application is hindered
by significant volumetric fluctuations during lithiation/delithiation, alongside
a metastable nature, which induces mechanical instability and irreversible lithium
consumption, ultimately impairing long-term capacity retention in full-battery
cell configurations. In this study, we present a phase-engineering approach designed
to improve the structural stability of SiOx anodes for LIB applications. By incorporating
lithium fluoride, amorphous SiOx undergoes partial transformation into a quartz-like
phase, which enhances mechanical integrity and mitigates irreversible lithium
loss. This modified anode demonstrates significantly improved stability and prolonged
cycle lifespan. Through a combination of multiscale simulations and in situ characterizations,
we elucidate the stabilization mechanisms conferred by the quartz phase, providing
critical insights into the role of SiOx’s crystal structure in influencing degradation
pathways. This work introduces an accessible and efficient method for controlling
the crystallinity of SiOx, offering a practical solution to enhance the durability
of high-energy-density LIBs.

text: The transverse thermoelectric (Nernst) effect is a powerful probe for studying
the electronic and structural properties of materials. In this study, we employ
transverse thermoelectric measurements to investigate the ferroelectric distortion
in the topological crystalline insulator (TCI) Pb0.60Sn0.40Te, a compound derived
from PbTe and SnTe, known for their exceptional thermoelectric performance and
distinct ferroelectric properties. By leveraging Nernst measurements, we provide
direct evidence of ferroelectric distortion in this TCI, corroborated by Shubnikov–de
Haas quantum oscillations that confirm the presence of two topologically nontrivial
Fermi pockets. Density functional theory calculations show that these pockets
originate from the L and T points in the Brillouin zone of the distorted structure
within the TCI phase. Raman spectroscopy further identifies a structural phase
transition below 50 K, consistent with the quantum oscillation observations. This
observation is further substantiated by temperature-dependent synchrotron X-ray
pair distribution function analysis and transmission electron microscopy, which
confirm the local off-centering of cations at low temperature. These findings
underscore the potential of transverse thermoelectric measurements in unveiling
ferroelectric distortions and their role in modulating topological quantum states,
opening new directions for research into the synergy between ferroelectricity
and topological phases.
