Abstract Controlling the concentrations of H 2 O and CO at reaction interface is crucial for achieving efficient electrochemical reduction. However, precise control these variables during catalysis remains challenging, underlying mechanisms are not fully understood. Herein, guided by a multi-physics model, we demonstrate that tuning local O/CO achievable thin polymer coatings on catalyst surface. Beyond often-explored hydrophobicity, properties gas permeability water-uptake ability even more...

Motivated by the recent discovery of superconductivity in ${\mathrm{La}}_{3}{\mathrm{Ni}}_{2}{\mathrm{O}}_{7}$ under pressure, we discuss basic ingredients a model that captures its microscopic physics pressure tuning. We anchor our description terms spectroscopic evidence strong correlations this system. In bilayer Hubbard including Ni $3d$ ${x}^{2}\ensuremath{-}{y}^{2}$ and ${z}^{2}$ orbitals, show ground state crosses over from low-spin $S=1/2$ to high-spin $S=3/2$ state. state, two...

Fully dense hydroxyapatite (HAp) nanobioceramics with enhanced mechanical properties were fabricated via two‐step sintering (TSS) process. The effects of parameters on the microstructures and HAp bioceramics investigated. results showed that grain growth could be effectively suppressed TSS size was 193 nm for samples 99.02% relative density. Comparing conventional process, hardness (4.86 GPa) fracture toughness (1.18 MPa m 1/2 ) by increased about 12% 57%, respectively. Therefore, provided a...

Abstract Strontium (Sr), Zinc (Zn), magnesium (Mg), and silicon (Si) are reported to be essential trace elements for the growth mineralization of bone. We speculated that combination these bioactive in bioceramics may effective regulate osteogenic property bone‐forming cells. In this study, two Sr‐containing silicate bioceramics, Sr 2 ZnSi O 7 (SZS) MgSi (SMS), were prepared. The biological response human bone marrow mesenchymal stem cells (BMSCs) (in forms powders dense ceramic bulks) was...

Abstract Non-volatile phase-change memory devices utilize local heating to toggle between crystalline and amorphous states with distinct electrical properties. Expanding on this kind of switching two topologically phases requires controlled non-volatile symmetries. Here, we report the observation reversible stable closely related crystal structures, remarkably electronic in near-room-temperature van der Waals ferromagnet Fe 5− δ GeTe 2 . We show that is enabled by ordering disordering site...

The neutrophil percentage-to-albumin ratio (NPAR) emerges as a novel inflammation marker, demonstrating prognostic ability in variety of cardiovascular diseases. However, its impact on mortality among patients undergoing maintenance hemodialysis (MHD) remains uncertain. Our research aims to determine whether NPAR is reliable predictor MHD patients. A total 1803 were recruited this prospective cohort. Patients stratified into three groups based baseline levels. association between and...

Abstract RFeO 3 orthoferrites, where R is a rare-earth ion of the lanthanide series, are attracting attention mostly because their promising fast spin dynamics. The magnetic properties these materials seem to crucially depend on whether magnetizations and Fe ions’ weak ferromagnetic (WFM) components parallel or antiparallel each other. Here, we report an extensive investigation high-quality DyFeO single crystal in which induced Dy 3+ magnetization (F ) has natural tendency be sublattice...

We investigated the magnetotransport properties of Fe-doped topological insulator $\mathrm{S}{\mathrm{b}}_{1.96}\mathrm{F}{\mathrm{e}}_{0.04}\mathrm{T}{\mathrm{e}}_{3}$ single crystals. With doping, band structure changes significantly and multiple Fermi pockets become evident in Shubnikov--de Haas oscillations, contrast to frequency detected for pure $\mathrm{S}{\mathrm{b}}_{2}\mathrm{T}{\mathrm{e}}_{3}$. Using complementary density functional theory calculations, we identify an additional...
