text: Developing cost-effective and high-performance thermoelectric (TE) materials
to assemble efficient TE devices presents a multitude of challenges and opportunities.
Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant
elements. However, the challenge lies in its poor electrical conductivity. Herein,
an efficient and scalable solution-based approach is developed to synthesize high-quality
Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement
and annealing treatments, the dried powders are consolidated into dense pellets,
and their TE properties are investigated. Pb doping effectively increases the
charge carrier concentration, resulting in a significant increase in electrical
conductivity, while the Seebeck coefficients remain consistently high. The calculated
band structure shows that Pb doping induces band convergence, thereby increasing
the effective mass. Furthermore, the large ionic radius of Pb2+ results in the
generation of additional point and plane defects and interphases, dramatically
enhancing phonon scattering, which significantly decreases the lattice thermal
conductivity at high temperatures. Overall, a maximum figure of merit (zTmax)
≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold
increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based
materials produced by solid-state, demonstrating advantages of versatility and
cost-effectiveness using a solution-based technology.

text: Development of electroactive materials exhibiting high performance with superior
stability is crucial in the field of supercapacitors and battery research. We
report on synthesis of highly stable composite of semi-polycrystalline polyaniline
and graphene (SPani-graphene) and its application in supercapacitor electrodes.
The electrochemical behavior and device performance of the electrodes were investigated
through cyclic voltammetry (CV), galvanostatic charge-discharge GCD) and electrochemical
impedance spectroscopy (EIS) in a 3-electrode and a 2-electrode (device) cell
configurations, repectively. The cell specific capacitance (Cell Csp) achieved
from the 2-electrode symmetric cell configuration was 525.5 F g−1 at 0.1 A g−1
using polymer gel electrolyte (PGE). The PGE in this work is xanthan gum jellied
in 1 M aq. Na2SO4. The maximum energy density and power density achieved from
the device was 46.7 Wh kg−1 and 16.16 kW kg−1, respectively, at 0.4 A g−1. Furthermore,
the device exhibits an excellent retention of cell specific capacitance and coulombic
efficiency of 97 % and 94 %, respectively, over 10,000 continuous GCD cycles,
indicating an excellent rate capability as well as a promising power management.
To investigate the material's electrochemical durability, a detailed EIS study
has been carried out using both, 3-electrode, and 2-electrode cell configurations,
before and after long cycling test (over 10,000 continuous GCD cycles). Our thorough
experimentation delivers satisfactory results and has been explained in detail
in the manuscript. Hereby, we propose that the EIS technique can be adopted for
investigating materials' electrochemical stability, in addition to long CV and
GCD cycles in the field of supercapacitors and battery research.

text: The electroreduction of biomass-derived benzaldehyde (BZH) provides a potentially
cost-effective route to produce benzyl alcohol (BA). This reaction competes with
the electrochemical self-coupling of BZH to hydrobenzoin (HDB), which holds significance
as a biofuel. Herein, we demonstrate the selectivity towards one or the other
product strongly depends on the surface chemistry of the catalyst, specifically
on its ability to adsorb hydrogen, as showcased with Cu2S electrocatalysts. We
particularly analyze the effect of surface ligands, oleylamine (OAm), on the selective
conversion of BZH to BA or HDB. The effect of the electrode potential, electrolyte
pH, and temperature are studied. Results indicate that bare Cu2S exhibits higher
selectivity towards BA, while OAm-capped Cu2S promotes HDB formation. This difference
is explained by the competing adsorption of protons and BZH. During the BZH electrochemical
conversion, electrons first transfer to the C in the C[double bond, length as
m-dash]O group to form a ketyl radical. Then the radical either couples with surrounding
H+ to form BA or self-couple to produce HDB, depending on the H+ availability
that is affected by the electrocatalyst surface properties. The presence of OAm
inhibits the H adsorption on the electrode surface therefore reducing the formation
of high-energy state Had and its combination with ketyl radicals to form BA. Instead,
the presence of OAm promotes the outer sphere reaction for obtaining HDB.

text: High-entropy materials (HEMs) offer a quasi-continuous spectrum of active
sites and have generated great expectations in fields such as electrocatalysis
and energy storage. Despite their potential, the complex composition and associated
surface phenomena of HEMs pose challenges to their rational design and development.
In this context, we have synthesized FeCoNiPdWP high entropy phosphide (HEP) nanoparticles
using a low-temperature colloidal method, and explored their application as bifunctional
electrocatalysts for the oxygen evolution and reduction reactions (OER/ORR). Our
analysis provides a detailed understanding of the individual roles and transformations
of each element during OER/ORR operation. Notably, the HEPs exhibit an exceptionally
low OER overpotential of 227 mV at 10 mA cm−2, attributed to the reconstructed
HEP surface into a FeCoNiPdW high entropy oxyhydroxide with high oxidation states
of Fe, Co, and Ni serving as the active sites. Additionally, Pd and W play crucial
roles in modulating the electronic structure to optimize the adsorption energy
of oxygen intermediates. For the ORR, Pd emerges as the most active component.
In the reconstructed catalyst, the strong d–d orbital coupling of especially Pd,
Co, and W fine-tunes ORR electron transfer pathways, delivering an ORR half-wave
potential of 0.81 V with a pure four-electron reduction mechanism. The practicality
of these HEPs catalysts is showcased through the assembly of aqueous zinc–air
batteries. These batteries demonstrate a superior specific capacity of 886 mA

operation. Overall, this study not only elucidates the role of each element in
HEMs but also establishes a foundational framework for the design and development
of next-generation bifunctional oxygen catalysts, broadening the potential applications

text: We explore the potential of nanocrystals (a term used equivalently to nanoparticles)
as building blocks for nanomaterials, and the current advances and open challenges
for fundamental science developments and applications. Nanocrystal assemblies
are inherently multiscale, and the generation of revolutionary material properties
requires a precise understanding of the relationship between structure and function,
the former being determined by classical effects and the latter often by quantum
effects. With an emphasis on theory and computation, we discuss challenges that
hamper current assembly strategies and to what extent nanocrystal assemblies represent
thermodynamic equilibrium or kinetically trapped metastable states. We also examine
dynamic effects and optimization of assembly protocols. Finally, we discuss promising
material functions and examples of their realization with nanocrystal assemblies.

text: Broadband photodetectors that can decipher the wavelength (λ) and intensity
(I) of an unknown incident light are urgently demanded. Photothermoelectric (PTE)
detectors can achieve ultrabroadband photodetection surpassing the bandgap limitation;
however, their practical application is severely hampered by the lack of deciphering
strategy. In this work, we report a variable elimination method to decipher λ
and I of the incident lights based on an integrated Ag2Se film-based PTE detector.
Nanostructured Ag2Se films with controlled thickness are synthesized using an
ion sputtering of Ag and a room-temperature selenization method and then assembled
into a detector. Under identical illumination, Ag2Se films of different thicknesses
produce varying output photothermal voltages, influenced by factors including
λ. By establishing a direct relationship between the photothermal voltage and
the absorption of Ag2Se films of varied thickness, we successfully eliminate variables
independent of λ, thus determining λ. Subsequently, I is determined by the calibrated
responsivity relationship using obtained λ. Our PTE detector achieves a broadband
spectrum from 400 to 950 nm and high accuracy, with deviations as low as ∼2.63
and ∼0.53% for deciphered λ and I, respectively. This method allows for self-powered
broadband decipherable photodetection without a complex device architecture or
computational assistance, which could boost the research enthusiasm and promote
the commercialization of PTE broadband detectors.

text: We report on synthesis of highly crystalline polythiophene and its application
in supercapacitor electrodes. The material exhibits a remarkably stable electrochemical
behavior and an excellent device performance. The device delivers an electrode
specific capacitance (Csp) of 129.13F g−1, Cell Csp of 32.28F g−1 at 0.5 A/g;
energy, and power densities of ∼ 3 Wh kg−1 and 250 W kg -1, respectively at 0.5
A/g. Also, it exhibits an excellent retention of Cell Csp and coulombic efficiency
up to ∼ 95 % over 10,000 continuous galvanostatic charge discharge (GCD) cycles
indicating a remarkable performance by a standalone, pristine and undoped polythiophene.
Electrochemical impedance spectroscopy (EIS) studies further suggest material’s
stable capacitive behavior. The material’s enhanced electrochemical properties,
stable behavior and outstanding performance in device application are attributed
to the crystalline phases present in the polymer matrix achievable via a slow
rate of synthesis; overall, an edge over other conventional synthesis methods.

text: Identifying efficient active sites for the direct synthesis of hydrogen peroxide
over Pd-based catalysts has been a subject of considerable debate. In this study,
we employ particle swarm optimization method and density functional theory to
explore the H2O2 synthesis mechanism on Pd, PdO, and the partially oxidized surface
(Pd9OX). A comprehensive mechanism for Pd9OX is elucidated, and subsequent coverage-dependent
kinetic analysis allows for a quantitative assessment of catalytic performance
at the interphase. Our findings conclusively establish that the interphase between
Pd and PdO represents the optimal active site. Phase diagram analysis further
aids in determining stable structures under reaction conditions. At 298.15 K and
under oxygen balance, the Pd9O6 surface remains stable throughout the reaction,
demonstrating high activity and selectivity. This work underscores the significance
of the interphase in comprehending catalytic performance and unveils promising
avenues for optimizing catalyst performance by controlling reaction conditions
and surface composition.

text: "Locomotion is ubiquitous in the animal kingdom because an animal's survival
depends on its ability to navigate its environment to find food, avoid predators
and locate potential mates. These behaviours require control mechanisms that can
extract information from the environment, particularly visual cues. Selective
evolutionary pressures have thus refined such visuomotor transformations in a
species-specific manner to meet the specific ecological and ethological challenges
of each organism. However, a common challenge across organisms as visual information
processing\r\nbecomes increasingly detailed is the mechanisms required to synthesise
disparate pieces of information into a coherent percept or unified picture of
the world. In this thesis, I investigate how disparate visual information is combined
in the brain of Drosophila melanogaster to effectively guide locomotion.\r\nFor
this, I first designed and built a behavioural setup to record locomotion and
present visual stimuli to freely-walking fruit flies in a closed-loop manner.
This setup allowed the investigation of innate visually-guided behaviours, including
the optomotor reflex and courtship.\r\nSecond, taking advantage of my system I
investigated the optomotor response, a reflexive visual stabilisation behaviour
in which flies turn in the direction of global motion to minimise retinal slip.
This behaviour is thought to be mediated by Lobula plate tangential cells (LPTCs);
a complex network of optic-flow-sensitive neurons essential for self-motion estimation.
Using a novel genetic mutant, I demonstrate that electrical coupling between two
LPTC subtypes, contralateral HS and H2 neurons, regulates the balance between
smooth optomotor turning and saccadic anti-optomotor responses. These findings
underscore the critical role of binocular motion cue integration in guiding course
control. Finally, I developed a novel behavioural paradigm in which a sexually
aroused male fruit fly is presented with an optomotor distractor. This setup creates
competition between two visual behaviours, courtship tracking and the optomotor
response, enabling me to explore how the visual system resolves this conflict.
In this setting, males\r\nengaged in courtship selectively suppress their optomotor
response based on the female's location. Furthermore, when this experiment is
replicated with an “artificial female”, optogenetically aroused males alternate
between tracking and optomotor responses. The probability and dynamics of this
switching are determined by the relative strengths of the two competing stimuli.
In summary, the results presented in this thesis explore two mechanisms – integration
and competition - through which visual information is combined in the brain of
the fruit fly to drive locomotion."

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: Animals rely on compensatory actions to maintain stability and navigate their
environment efficiently. These actions depend on global visual motion cues known
as optic-flow. While the optomotor response has been the traditional focus for
studying optic-flow compensation in insects, its simplicity has been insufficient
to determine the role of the intricate optic-flow processing network involved
in visual course control. Here, we reveal a series of course control behaviours
in Drosophila and link them to specific neural circuits. We show that bilateral
electrical coupling of optic-flow-sensitive neurons in the fly’s lobula plate
are required for a proper course control. This electrical interaction works alongside
chemical synapses within the HS-H2 network to control the dynamics and direction
of turning behaviours. Our findings reveal how insects use bilateral motion cues
for navigation, assigning a new functional significance to the HS-H2 network and
suggesting a previously unknown role for gap junctions in non-linear operations.

text: We used diverse methods to characterize the role of avian lateral spiriform
nucleus (SpL) in basal ganglia motor function. Connectivity analysis showed that
SpL receives input from globus pallidus (GP), and the intrapeduncular nucleus
(INP) located ventromedial to GP, whose neurons express numerous striatal markers.
SpL-projecting GP neurons were large and aspiny, while SpL-projecting INP neurons
were medium sized and spiny. Connectivity analysis further showed that SpL receives
inputs from subthalamic nucleus (STN) and substantia nigra pars reticulata (SNr),
and that the SNr also receives inputs from GP, INP, and STN. Neurochemical analysis
showed that SpL neurons express ENK, GAD, and a variety of pallidal neuron markers,
and receive GABAergic terminals, some of which also contain DARPP32, consistent
with GP pallidal and INP striatal inputs. Connectivity and neurochemical analysis
showed that the SpL input to tectum prominently ends on GABAA receptor-enriched
tectobulbar neurons. Behavioral studies showed that lesions of SpL impair visuomotor
behaviors involving tracking and pecking moving targets. Our results suggest that
SpL modulates brainstem-projecting tectobulbar neurons in a manner comparable
to the demonstrated influence of GP internus on motor thalamus and of SNr on tectobulbar
neurons in mammals. Given published data in amphibians and reptiles, it seems
likely the SpL circuit represents a major direct pathway-type circuit by which
the basal ganglia exerts its motor influence in nonmammalian tetrapods. The present
studies also show that avian striatum is divided into three spatially segregated
territories with differing connectivity, a medial striato-nigral territory, a
dorsolateral striato-GP territory, and the ventrolateral INP motor territory.

text: "A thermoelectric cooler is a solid-state device that transfers heat from
one side to another when an electrical current passes through it. This technology
is appealing because it can provide precise and localized cooling and heating
without using hazardous liquids or gases commonly found in traditional vapor compression
refrigeration. These devices are compact, customizable in size, work in any orientation,
operate noiselessly, and require minimal maintenance. Even though thermoelectric
coolers could be transformative for many advanced thermal management applications,
their widespread adoption is hindered by the low efficiency of the thermoelectric
materials and costly manufacturing processes.\r\n In this work, we use extrusion-based
3D printing techniques to fabricate high-performance thermoelectric materials
using nanomaterial-based ink. The ink formulation is optimized to ensure structural
integrity and particle interfacial bonding during annealing, providing p- and
n-type materials with record-high zT values of 1.46 and 1.35 at room temperature,
respectively. Moreover, we integrate the printed materials into a 32-pair device
and achieve a significant cooling temperature gradient of 50 °C and a coefficient
of performance of 3.8, comparable to best-performing thermoelectric coolers, avoiding
material waste, and the energy-intense and inefficient steps, such as high-temperature
synthesis, pressure-assisted sintering, and cutting and dicing ingots, commonly
used in conventional manufacturing processes."

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.

text: A detailed structural, magnetic as well as dielectric dynamics study is carried
out to investigate the influence of Bi3+ on YCrO3. All the samples crystalize
in orthorhombic structure with Pnma symmetry and the grains are mostly stretched
with Bi. A coexisting tunable fraction of both antiferromagnetic (AFM) and weak
ferromagnetic (WFM) phases is acquired by the system down to Low-T. An abnormal
negative magnetization in zero field is correlated to the competition among AFM
and WFM phases. Maximum magnetization decreases while the coercivity first increases
and then decreases with Bi is correlated to the competing effect between the local
deformation and Cr–O–Cr exchange interaction. The magnetodielectric coupling with
improved permittivity might be associated with the 6s2 lone pair electron of Bi3+.
Furthermore, ac-conductivity increases with a decrease in activation energy (0.27–0.11
eV), is explained in the framework of structural model and charge carrier hopping
between Cr3+ and Cr4+ ions.

text: 'MaxCut is a classical NP-complete problem and a crucial building block in
many combinatorial algorithms. The famous Edwards-Erdős bound states that any
connected graph on n vertices with m edges contains a cut of size at least m/2+(n-1)/4.
Crowston, Jones and Mnich [Algorithmica, 2015] showed that the MaxCut problem
on simple connected graphs admits an FPT algorithm, where the parameter k is the
difference between the desired cut size c and the lower bound given by the Edwards-Erdős
bound. This was later improved by Etscheid and Mnich [Algorithmica, 2017] to run
in parameterized linear time, i.e., f(k)⋅ O(m). We improve upon this result in
two ways: Firstly, we extend the algorithm to work also for multigraphs (alternatively,
graphs with positive integer weights). Secondly, we change the parameter; instead
of the difference to the Edwards-Erdős bound, we use the difference to the Poljak-Turzík
bound. The Poljak-Turzík bound states that any weighted graph G has a cut of size
at least (w(G))/2+(w_MSF(G))/4, where w(G) denotes the total weight of G, and
w_MSF(G) denotes the weight of its minimum spanning forest. In connected simple
graphs the two bounds are equivalent, but for multigraphs the Poljak-Turzík bound
can be larger and thus yield a smaller parameter k. Our algorithm also runs in
parameterized linear time, i.e., f(k)⋅ O(m+n).'

text: "There are a number of well-known problems and conjectures about partitioning
graphs to satisfy local constraints. For example, the majority colouring conjecture
of Kreutzer, Oum, Seymour, van der Zypen and Wood states that every directed graph
has a 3-colouring such that for every vertex v, at most half of the out-neighbours
of v have the same colour as \r\n. As another example, the internal partition
conjecture, due to DeVos and to Ban and Linial, states that for every d, all but
finitely many d-regular graphs have a partition into two non-empty parts such
that for every vertex v, at least half of the neighbours of v lie in the same
part as v. We prove several results in this spirit: in particular, two of our
results are that the majority colouring conjecture holds for Erdős–Rényi random
directed graphs (of any density), and that the internal partition conjecture holds
if we permit a tiny number of ‘exceptional vertices’. Our proofs involve a variety
of techniques, including several different methods to analyse random recolouring
processes. One highlight is a personality-changing scheme: we ‘forget’ certain
information based on the state of a Markov chain, giving us more independence
to work with."

text: "The inertia bound and ratio bound (also known as the Cvetković bound and
Hoffman bound) are two fundamental inequalities in spectral graph theory, giving
upper bounds on the independence number α(G) of a graph G in terms of spectral
information about a weighted adjacency matrix of G. For both inequalities, given
a graph G, one needs to make a judicious choice of weighted adjacency matrix to
obtain as strong a bound as possible.\r\nWhile there is a well-established theory
surrounding the ratio bound, the inertia bound is much more mysterious, and its
limits are rather unclear. In fact, only recently did Sinkovic find the first
example of a graph for which the inertia bound is not tight (for any weighted
adjacency matrix), answering a longstanding question of Godsil. We show that the
inertia bound can be extremely far from tight, and in fact can significantly underperform
the ratio bound: for example, one of our results is that for infinitely many n,
there is an n-vertex graph for which even the unweighted ratio bound can prove
α(G)≤4n3/4, but the inertia bound is always at least n/4. In particular, these
results address questions of Rooney, Sinkovic, and Wocjan--Elphick--Abiad."
