β-SnSe is one of the most promising thermoelectric materials with low thermal conductivity and a high power.
Wearable pressure sensors are highly desirable for monitoring human health and realizing a nice human-machine interaction. Herein, chitosan/MXene/polyurethane-sponge/polyvinyl alcohol (CS/MXene/PU sponge/PVA)-based 3D sensor is developed to simultaneously achieve wearability, washability, high sensitivity in wide region. In the force-sensitive layer of sensor, MXene CS fully attached PU sponge ensure that composite has remarkable conductivity washability. Benefiting from resistive...
The electronic coordination configuration of metal active sites and the reaction mechanism were investigated by constructing homo-diatomic Fe for visible-light-assisted heterogeneous peroxymonosulfate (PMS) activation. A novel Fe2N6 catalyst was synthesized selecting uniform pyridinic-N graphitic carbon nitride (g-C3N4) as anchoring sites. results demonstrated that modulated d-band center electron delocalization thus enhanced PMS activation kinetics (3.58 times vs single-atom catalyst) with...
Abstract Layered oxides represent a prominent class of cathodes employed in lithium‐ion batteries. The structural degradation layered causes capacity decay during cycling, which is generally induced by anisotropic lattice strain the bulk cathode particle and oxygen release at surface. However, particularly lithium‐rich (LLOs) that undergo intense redox reactions, challenge simultaneously addressing surface issues through singular modification technique remains arduous. Here thin (1‐nm)...
Singlet oxygen (1O2) is an excellent reactive species in advanced oxidation processes for water purification due to its environmental suitability and selectivity. However, generation conversion mechanisms remain unclear. Herein, we have constructed a high-yield system 1O2 by introducing ozone (O3) into iron single-atom catalyst/peroxymonosulfate (PMS) system. The steady-state concentration of the was increased 53.2% at O3 below 0.5 mg/L. formation from high-valent iron-oxo (FeIV═O) revealed...
Using density functional theory (DFT) calculations, we have systematically investigated the thermodynamic properties and structural stabilities of thorium dioxide (ThO2).Based on calculated phonon dispersion curves, calculate thermal expansion coefficient, bulk modulus, heat capacities at different temperatures for ThO2 under quasi-harmonic approximation.All results are in good agreement with corresponding experiments proving validity our methods.Our theoretical studies can help people more...
Abstract Flexible sensors are required to be lightweight, compatible with the skin, sufficiently sensitive, and easily integrated extract various kinds of body vital signs during continuous healthcare monitoring in daily life. For this, a simple low-cost flexible temperature force sensor that uses only two carbon fiber beams as sensing layer is reported this work. This simple, can not monitor skin changes real time but also most pulse waves, including venous from parts human body. A...
We investigated the vibrational property of lead telluride (PbTe) with a focus on lattice anharmonicity at moderate temperatures $(300<T<800$ K) using phonon quasiparticle approach which combines first-principles molecular dynamics and dynamics. The calculated anharmonic dispersions are strongly temperature dependent some modes adopt giant frequency shifts, e.g., transverse optical in long-wavlength regime. As result, we witness avoided crossing between longitudinal acoustic elevated...
Two-dimensional homogeneous h-BCN atomic layers with a full range of compositions were synthesized by ion beam sputtering deposition.
Abstract The traditional three-phonon scattering approach cannot adequately reflect the anharmonic phonon properties of ZrS 2 system due to its strong intrinsic anharmonicity. In this study, vibrational and lattice thermal conductivity both bulk monolayer were investigated using large-scale machine learning force field molecular dynamics simulations approach, where all orders interactions between phonons caused by temperature considered. At finite temperatures, predicted Raman-active...
The phase transition structure and dynamical mechanisms of solid-state bcc iron (Fe)under extreme conditions remain an open question. This study systematically investigates the process mechanisms...
Covalent organic frameworks (COFs) have been regarded as promising cathode materials for lithium batteries. However, they generally show low practical capacity. Here we report the design, preparation, and battery application of a highly crystalline two‐dimensional truxenone‐based COF (TRO‐BT‐COF) with rich redox active sites, realizing high In‐situ characterizations theoretical calculations indicate that lithiation reaction proceeds successively on C=O C=N groups TRO‐BT‐COF. One ring...
