Exploring efficient and inexpensive oxygen evolution reaction (OER) electrocatalysts is of great importance for various electrochemical energy storage conversion technologies. Ni-based have been actively pursued because their promising activity earth abundance. However, the OER efficiency most developed has intrinsically limited due to low electrical conductivity poor active site exposure yield. Herein, we report metallic Ni3N nanosheets as an electrocatalyst first time. The first-principles...
Abstract The introduction of heteroatoms is one the most important ways to modulate intrinsic electronic structure electrocatalysts improve their catalytic activity. However, for transition metal chalcogenides with highly symmetric crystal (HS‐TMC), heteroatoms, especially those large atomic radius, often induces lattice distortion and vacancy defects, which may lead structural phase doped materials or reconstruction during reaction. Such unpredictable situations will make it difficult...
Ar plasma etching and annealing are highly robust in generating oxygen related single photon emitters hBN.
A two-step metal assisted chemical etching technique is used to systematically vary the sidewall roughness of Si nanowires in vertically aligned arrays. The thermal conductivities nanowire arrays are studied using time domain thermoreflectance and compared their high-resolution transmission electron microscopy determined roughness. conductivity with small close a theoretical prediction based on an upper limit mean-free-paths phonons given by diameter. large found be significantly below this...
We perform a comprehensive study of the effects line defects on electronic and magnetic properties monolayer boron-nitride (BN) sheets, nanoribbons, single-walled BN nanotubes using first-principles calculations Born-Oppenheimer quantum molecular dynamic simulation. Although divide sheet (or nanotube) into domains, we show that certain can lead to tailor-made edges sheets imperfect significantly reduce band gap or nanotube. In particular, find line-defect-embedded zigzag nanoribbons...
Introduction of defects in a controllable way is important to modulate the electronic structure catalysts toward enhancement electrocatalytic activity. Herein we report that incorporation fluorine into cobalt phosphide alloy has unique effect: it creates both F– anion doping and P vacancies, resulting nearly 15-fold catalytic activity for hydrogen evolution reaction (HER) neutral solution. The existence dual CoP was confirmed by extended X-ray absorption fine (EXAFS) curve fitting results...
Abstract Nonmetal heteroatom incorporation into the lattice of host materials is a common way to regulate surface electronic structure electrocatalysts boost their electrocatalytic performance. However, will inevitably trigger strain and vacancy, which may lead large changes in materials. In this situation, reconstruction doped catalysts easily occurs during catalytic process under harsh alkaline media, hinders understanding structure–activity correlation between Herein, taking cobalt...
Ferromagnetic two-dimensional (2D) ultrathin nanosheets hold great promise for next generation electronics. metal-free materials that usually possess only an s/p electronic configuration with weak spin-orbit coupling and a large spin relaxation time, would play important role in constructing future spintronic devices. However, the absence of intrinsic ordering structure most greatly hampers widening scope ferromagnetic 2D nanostructures as well in-depth understanding their nature. Herein,...
Abstract Mpox (monkeypox) infection cases increased recently in non-Mpox outbreak areas, potentially causing an international threat. The desire to defend against a potential has led renewed efforts develop vaccines. In this report, mice were immunized with various doses of modified vaccinia virus Ankara (MVA) evaluate the cross-reactive immune response MVA immunization protective antigens current monkeypox virus. We demonstrated that induced specific antibodies (A29, A35, B6, M1, H3, and...
The development of one-dimensional (1D) molecular nanowires with high spin-polarization is important for both fundamental research and practical applications in nanoscale spintronics.

Among considered, CrH3, MnH3, CoH3 are either antiferromagnetic or ferromagnetic ground states. In particular, nanowire a half-metal, which ideally...
Exploring two-dimensional (2D) room-temperature magnetic materials in the field of 2D spintronics remains a formidable challenge. The vast array nonmagnetic provides abundant resources for exploration, but strategy to convert them into intrinsic magnets elusive. To address this challenge, we present general based on surface halogenation transition from nonmagnetism ferromagnetism MoS2 first-principles calculations. derived halogenated are half-semimetals with high Curie temperature (TC)...
Existing theory and data cannot quantify the contribution of phonon drag to Seebeck coefficient (S) in semiconductors at room temperature. We show that this is possible through comparative measurements between nanowires bulk. Phonon boundary scattering completely quenches silicon enabling quantification its S bulk range 25-500 K. The surprisingly large (∼34%) 300 K even doping ∼3 × 10(19) cm(-3). Our results contradict notion negligible degenerate temperatures relevant for thermoelectric...

The quantum anomalous Hall state with a large band gap and high Chern number is significant for practical applications in spintronics. By performing first-principles calculations, we investigate electronic properties of the fully fluorinated $1T\text{\ensuremath{-}}{\mathrm{MoSe}}_{2}$ monolayer. Without considering spin-orbit coupling, structure demonstrates single-spin semimetallic trigonal warping around ${K}_{\ifmmode\pm\else\textpm\fi{}}$ valleys. introduction coupling opens...
Platinum-based chemotherapy resistance is a key factor of poor prognosis and recurrence in hepatocellular carcinoma (HCC). Herein, RNAseq analysis revealed that elevated tubulin folding cofactor E (TBCE) expression associated with platinum-based resistance. High TBCE contributes to worse prognoses earlier among liver cancer patients. Mechanistically, silencing significantly affects cytoskeleton rearrangement, which turn increases cisplatin-induced cycle arrest apoptosis. To develop these...
Starting from the large photofragmentation cross sections recently reported for mass-selected alkali–halide cluster and nanocrystal beams [X. Li, R. D. Beck, L. Whetten, Phys. Rev. Lett. 68, 3420 (1992)], we have obtained optical absorption spectra ionic compound clusters in ultraviolet charge-transfer bands. The smaller members of CsI series, 3<n<14, show distinct edges 4.6–5.8 eV region—just below bulk exciton band near 5.9 eV—and smallest with an onset is Cs14I13+, which...
First-principles calculations reveal the electronic and magnetic properties of 2D FeCl toward spintronic applications.
Recently, the negative differential thermal resistance effect was discovered in a homojunction made of expansion material, which is very promising for realizing macroscopic transistors. Similar to Monte Carlo phonon simulation deal with grain boundaries, we introduce positive temperature-dependent interface modified Lorentz gas model and find effect. In homojunction, reproduce pair equivalent effects different temperature gradient directions. heterojunction, realize unidirectional effect, it...
