A series of 2D transition metal borides (MBenes) are reported and their properties as anode materials for LIBs investigated.

Ultrastable foams are made very simply by adding salt (NaCl or KCl) to sodium dodecyl sulfate. The addition of high concentrations leads the precipitation surfactant on bubble surfaces and as crystals in interstices between bubbles. As a consequence, ageing is stopped make them stable indefinitely, until they heated above melting temperature crystals. use KCl shown be much more effective than that NaCl because potassium sulfate has higher faster rates crystallization. crystalline structures...

Foams are ultrastable when all the aging processes arrest. We make such foams by precipitating sodium dodecyl sulfate with potassium chloride during foaming process. The precipitate crystals adsorb onto bubble surfaces to arrest coarsening and stop drainage blocking in interstices around bubbles. However, if concentration of SDS is too high, no longer ultrastable. transition sudden corresponds point at which significant remains solution. presence noncrystallized surfactant allows foam...

Phase separation of SCN-H2O ([CH2CN]2-H2O) transparent solutions is simulated in two dimensions and the effects quenching temperature initial composition on pattern formation dynamic behavior second phase are examined via Minkowski functionals. The simulation based model H where molar free energy solution obtained by CALPHAD approach. We find that do not affect exponent domain growth law, average size with time yields R(t)-t n . However, they influence separation. Lower leads to a finer...

Metal-organic frameworks (MOFs) possess an ordered and size-controllable porous structure, making them interesting heterogeneous confining environment for water. Herein, molecular dynamics simulations are employed to investigate the structure of confined water vapor in zeolitic imidazolate framework-8 (ZIF-8) nanopores. Water dimers, which rarely observed liquid or vapor, can form ZIF-8 at room temperature. The six-ring-member gate is main location a dimer ZIF-8. terminal methyl CH groups...

This work proposes a method for actively constructing acoustic metasurface (AMS) based on the split hollow cuboid (SHC) structure of local resonance, with designed AMS flexibly manipulating direction reflected waves at given frequency range. The was obtained by precisely adjusting any one or two types structural parameters SHC unit, which included diameter hole, length, width, height, and shell thickness SHC. simulation results showed that can manipulate waves, anomalous reflection angle...

The effect of mechanical deformation metal–organic frameworks on guest adsorption was investigated via a combination molecular dynamics and grand-canonical Monte Carlo simulations. volumetric uptake methane benefited from compressive IRMOF-1, whereas orientation influenced the gravimetric methane. structures IRMOF-1 enlarged sites, which could be subsequently occupied by additional molecules. However, both void fraction internal surface area decreased in strained IRMOF-1. rapid reduction...

Powder densification for specified shaped metal–organic frameworks (MOFs) is desirable most applications. The obtainment of such properties challenging, one which the rapid crystal-to-amorphous transition (framework collapse) MOFs under pressure. Herein, we found that residual guests MOF-5 synthesis process could form binding groups based on hydrogen-bonding networks water. improved processability and ease compression, did not promote structure collapse, can be achieved in guest-loaded...

The calibration technique of pipelined ADCs has developed many years. This paper reviews the history and introduces some typical approaches. According to status technique, this predicts possible direction future work.

Herein, we used first-principles calculations and the particle swarm optimization technique to predict a highly incompressible W0.5Al0.5N phase with space group R3¯m(166). Our results reveal that this phase, which was characterized by negative formation enthalpy, is thermodynamically dynamically stable, as revealed absence of imaginary modes in phonon spectra. Furthermore, its energetic stability at pressure 15 GPa indicates feasible strategy for experimental synthesis. The high performance...

Flexible metal-organic framework (MOF) materials have the ability to perform stimulated sudden volume contractions, and thus attract increasing attention for use in potential applications such as: actuators or sensors. Here, structural transition of MIL-53(Cr) loaded with a high concentration CH3OH (CH3OH) guest molecules, which cause internal pressure due guest-guest interactions, was investigated. The triggering can be enhanced by molecule loadings (1 per unit cell (UC): 5 MPa, empty: 53 7...
