Free-standing boron nanocages or borospherenes have been observed recently for B40(-) and B40. There is evidence that a family of borospherenes may exist. However, the smallest borospherene is still not known. Here, we report experimental and computational evidence of a seashell-like borospherene cage for B28(-) and B…
The mechanism of high-temperature superconductivity in the iron-based superconductors remains an outstanding issue in condensed matter physics. The electronic structure plays an essential role in dictating superconductivity. Recent revelation of distinct electronic structure and high-temperature superconductivity in t…
Owing to direct band gap and strong spin-orbit coupling, monolayer transition-metal dichalcogenides (TMDs) exhibit rich new physics and great applicable potentials. The remarkable valley contrast and light emission promise such two-dimensional (2D) semiconductors a bright future of valleytronics and light-emitting dio…
Mn2O3-doped Fe2O3 hexagonal microsheets were prepared for the low-temperature selective catalytic reduction (SCR) of NO with NH3. These hexagonal microsheets were characterized by SEM, TEM, XRD, BET, XPS, NH3-TPD, H2-TPR, and in situ DRIFT and were shown to exhibit a considerable uniform hexagonal microsheet structure…
Herein, a proof-of-concept of novel hybrid rechargeable battery based on electrochemical reactions of both nickel-zinc and zinc-air batteries is demonstrated using NiO/Ni(OH)2 nanoflakes self-assembled into mesoporous spheres as the active electrode material. The hybrid battery operates on two sets of fundamentally di…
Graphene quantum dots (GQDs) with white fluorescence are synthesized by a microwave‐assisted hydrothermal method using graphite as the precursor. A solution‐processed white‐light‐emitting diode (WLED) is fabricated using the as‐prepared white fluorescent GQDs (white‐light‐emitting graphene quantum dots, WGQDs) doped 4…
The ion insertion properties of MoS 2 continue to be of widespread interest for energy storage. While much of the current work on MoS 2 has been focused on the high capacity four‐electron reduction reaction, this process is prone to poor reversibility. Traditional ion intercalation reactions are highlighted and it is…
Abstract Herein we develop a chemical etching method to produce porous two‐dimensional (2D) Ti 3 C 2 T x MXenes at room temperature in aqueous solutions. The as‐produced porous Ti 3 C 2 T x (p‐Ti 3 C 2 T x ) have larger specific surface areas and more open structures than their pristine counterparts, and can be fabric…
The temperature and time-dependent behaviors of thin-walled high-strain composites including structural nonlinearity are experimentally and numerically investigated. The high-strain composites using woven fabric fibers with heat-softenable resin of shape memory polymers are fabricated. The numerical model based on the…
This study demonstrates the synthesis and characterisation of core–shell particles for the removal of chlorides from water. The evaluation of their efficiency was conducted under a variety of experimental conditions. The core–shell particles consist of an organic template coated with Mg–Al–NO3 layered double hydroxide…
Strontium (Sr) containing rare‐earth oxysilicate apatite A I 4 A II 6 (SiO 4 ) 6 O 2 is considered a good matrix to accommodate radionuclide as its cation sites can incorporate lanthanide elements other than Sr. Here, we report a study on the synthesis of Nd 8 Sr 2 (SiO 4 ) 6 O 2 and Yb 8 Sr 2 (SiO 4 ) 6 O 2 , which a…
In this article, we put forward the possibility to prepare amorphous powder from chalcogenide compositions usually located out of the glassy domain when synthesized via a conventional melt‐quenching technique. Both X‐ray diffraction and DSC techniques were used to demonstrate that the original Ge 15 Ga 20 S 65 composi…
Melt processed bio‐nanocomposites of poly(butylene succinate) (PBS)‐chitosan (CS) generated with varying amounts of silica, alumina‐silicate, and thermally reduced graphene were analyzed for their biodegradation behavior. The nanocomposite samples were embedded in soil under natural environment for varying periods of…
Mullite–nickel nanocomposite fibers with Ni nanoparticles of controllable size, dispersion, and consequent magnetic properties were fabricated using sol–gel/electrospinning method, followed by thermal reduction. The fibers were electrospun from an aqueous solution containing sol–gel mullite precursor and nickel nitrat…
Strontium fluorapatite particles with tunable morphologies and geometries were successfully synthesized via a precipitation system by adjusting the pH value and temperature. Several analysis techniques were used to investigate and characterize the particles. The surface energy was calculated using first‐principle calc…

Single‐phase multiferroic Ba(Fe 0.67 Ce 0.33 ) 0.01 Ti 0.99 O 3 ( BFTO :Ce) and Ba(Fe 0.67 La 0.33 ) 0.01 Ti 0.99 O 3 ( BFTO :La) nanostructures were synthesized by a hydrothermal method (180°C/48 h). Rietveld refinement of X‐ray diffraction could confirm crystalline phase and lattice deformation by Ce, La into BFTO .…
This paper discusses the implementation of an explicit density-based solver, that utilises the central-upwind schemes for the simulation of cavitating bubble dynamic flows. It is highlighted that, in conjunction with the Monotonic Upstream-Centered Scheme for Conservation Laws (MUSCL) scheme they are of second order i…
