The superior additives-free dehydrogenation of formic acid for hydrogen production by uniform electron-deficient Pd clusters.
The effects of preheating to 50 ℃ and the subsequent application high-intensity ultrasound (HIU, 20 kHz) at 200, 400, 600, 800 W on physicochemical, structural, gelling properties wooden breast myofibrillar protein (WBMP) were studied. Results suggested that WBMP structure expanded balanced state 600 W, rheological exhibit HIU (P < 0.05) significantly improved storage modulus (G') WBMP. Notably, gel (600 W) had best hardness (65.428 ± 0.33 g), springiness (0.582 0.01), water-holding capacity...
Based on first-principles plane-wave calculations, functionalization of the two-dimensional single-layered GaSe structure through vacancy and chemical element doping has been investigated. Our calculations show that pristine monolayer, which is normally a non-magnetic, indirect-band-gap semiconductor, can induce net magnetic moments by introduction Ga mono-vacancy, di-vacancy, GaSe3 Ga2Se6 complexes. Magnetic also be induced selectively specific transition-metal atoms as well A group atoms....
We report the design and synthesis of uniform PdAu alloy nanoclusters immobilized on diamine graphene oxide-functionalized silica nanospheres. The structure-dependent activity for selectively catalytic dehydrogenation formic acid (FA) has been evaluated optimized by controlling Pd/Au mole ratio carrier components. relationship between catalyst structure investigated via both experiments characterization. High-resolution transmission electron microscopy (TEM) X-ray diffraction (XRD) proved...
A porous carbon CO2 adsorbent based on soybean cake (industrial biomass waste) has been successfully prepared by direct carbonation, following KOH activation. The exhibits efficient capture performance with the highest adsorption capacity of 4.19 and 6.61 mmol/g at 298 273 K under atmospheric pressure, respectively. Moreover, also shows good static a low pressure (0.15 bar) an uptake 1.26 equally ideal dynamic capability 1.28 (15% CO2) K. Additionally, adsorbed solution theory (IAST) model...
Synergistic catalysis of Au<sup>0</sup> and Au<sup>3+</sup> dual active sites confined in Silicalite-1 for selective solvent-free oxidation toluene to benzaldehyde with molecular oxygen.
Three-dimensional hollow porous superparamagnetic Fe3O4 microspheres were synthesized via a facile hydrothermal process. A series of characterizations done with X-ray diffraction, Brunauer-Emmett-Teller method, Fourier transform infrared spectroscopy, scanning electron microscopy, and transmission microscopy indicated that the production possessed good monodispersity, uniform size distribution, structural characters, strong behavior. The obtained have diameter ca. 300 nm, which is composed...
Abstract Chiral azobenzenes can be used as photoswitchable dopants to control supramolecular helices in liquid crystals. However, the lack of thermal stability cis ‐isomer precludes envisioning generation long‐lived with light. Here, this study demonstrates thermally stable and axially chiral azobenzene switches that create from (achiral) nematic Their trans ‐to‐ photoisomerization leads a variation helical twisting power reaches up 60%, superstructure is engineered light displays relaxation...
Abstract Bio‐ethanol dehydration to ethylene is an attractive alternative oil‐based ethylene. The influence of fusel, main byproducts in the fermentation process bio‐ethanol production, on should not be ignored. We studied catalytic over parent and modified HZSM‐5 at 250°C, with weight hourly space velocity (WHSV) equal 2.0/h. influences a series such as isopropanol, isobutanol isopentanol, ethanol catalysts were investigated. 0.5%La‐2%PHZSM‐5 catalyst exhibited higher conversion (100%),...
Azobenzene is a widely used guest molecule to build up dynamic photo-responsive host-guest systems. Here, we studied the complexation of water-soluble, ortho-fluorinated azobenzene with two different host molecules, cyclodextrin (β-CD) and cucurbit[8]uril (CB[8]), demonstrate that in presence both, forms stable supramolecular complexes selectively. In its trans-form, it favors binding β-CD, whereas cis-form CB[8]. Upon light-triggered photo-isomerization, photoswitch was reversibly...
Abstract A transmission electron microscopy study of the dislocation distribution under an indentation has revealed first that a complex sequence loop nucleation, cross-slip and renucleation results in cross-like network at free surface square-like underneath. These distributions are made up two types dislocation: redundant dislocations responsible for general plasticity work hardening, shielding equilibrium forces. The former roughly order magnitude more prevalent. total number consistent...

Nitrogen-doped yolk–shell carbon nanoparticles are one of the most promising functional nanomaterials for various potential applications because their functionality and adaptability in both hollow shells yolks. Yolk–shell nanospheres known widely adopted template-based routes, which prove to be expensive cumbersome showed inadequate capability build complex internal structures. Herein, a facile controllable strategy fabricating nitrogen-doped was proposed through simple leaching process. The...
The dehydrocoupling reaction between alcohols and hydrosilanes is considered to be one of the most atom-economical ways produce Si–O coupling compounds because its byproduct only hydrogen (H2), which make it extremely environmentally friendly. In past decades, various kinds homogeneous catalysts for hydrosilanes, such as transition metal complexes, alkaline earth metals, alkali noble have been reported their good activity selectivity. Nevertheless, practical applications these still remain...
