The development of efficient and low energy-consumption catalysts for CO2 conversion is desired, yet remains a great challenge. Herein, class novel hollow porous carbons (HPC), featuring well dispersed dopants nitrogen single Zn atoms, have been fabricated, based on the templated growth metal-organic framework precursor, followed by pyrolysis. optimized HPC-800 achieves catalytic cycloaddition with epoxides, under light irradiation, at ambient temperature, taking advantage an ultrahigh...
A simple nanoporous metal organic framework (MOF) bioreactor preparation via a low energy 30 minute vortex as driving force to immobilize trypsin enzyme is presented. No chemical modifications were employed thus wastes eliminated. The digestion efficiency of this exceptionally high, even when reused. This "green" synthesis procedure produced bioreactor.
Abstract The development of efficient and low energy‐consumption catalysts for CO 2 conversion is desired, yet remains a great challenge. Herein, class novel hollow porous carbons (HPC), featuring well dispersed dopants nitrogen single Zn atoms, have been fabricated, based on the templated growth metal–organic framework precursor, followed by pyrolysis. optimized HPC‐800 achieves catalytic cycloaddition with epoxides, under light irradiation, at ambient temperature, taking advantage an...
Abstract Phase transition in thermoelectric (TE) material is a double‐edged sword—it undesired for device operation applications, but the fluctuations near an electronic instability are favorable. Here, Sb doping used to elicit spontaneous composition fluctuation showing uphill diffusion GeTe that otherwise suspended by diffusionless athermal cubic‐to‐rhombohedral phase at around 700 K. The interplay between these two transitions yields exquisite and coexistence of cubic rhombohedral phases...
A comparison of the thermoelectric performance and compatibility between composite in this study other state-of-art IV–VI compounds.
Abstract Due to their amorphous‐like ultralow lattice thermal conductivity both below and above the superionic phase transition, crystalline Cu‐ Ag‐based argyrodites have garnered widespread attention as promising thermoelectric materials. However, despite intriguing properties, quantifying conductivities a comprehensive understanding of microscopic dynamics that drive these extraordinary properties are still lacking. Here, an integrated experimental theoretical approach is adopted reveal...
The nanosized effects of short-range multimagnon excitation behavior and short-circuit diffusion in NiO nanowalls synthesized using the Ni grid thermal treatment method were observed. energy dispersive spectroscopy mapping technique was used to characterize growth mechanism, confocal Raman scattering probe antiferromagnetic exchange J2 between next-nearest-neighboring ions at various temperatures below Neel temperature. This study shows that short spin correlation leads an exponential...
A mesoporous metal–organic framework of [Al(OH)(SDC)] (CYCU-3) (H2SDC = 4,4′-stilbenedicarboxylic acid) was synthesised by using Al(III) ions and H2SDC under solvothermal conditions. The structure forms 3D frameworks in which the carboxylate oxygen on each terminus ligand octahedral AlO6 corner-sharing. As verified N2 sorption measurements, CYCU-3 exhibits largest pore volume open channels (3.0 nm) system Al-MOFs reported to date. This Al-MOF also displays highly porous properties uptake...
Argyrodites with a general chemical formula of A8BX6 (A = Cu, Ag; B Si, Ge, Sn; and X S, Se, Te) are known for the intimate interplay among mobile ions, electrons, phonons, which yields rich material physics materials chemistry phenomena.
