Anatase TiO2 is considered as one of the promising anode materials for lithium ion batteries (LIBs) because its nontoxicity, safety, and excellent capacity retention. However, poor rate capability electrodes, caused by low electrical conductivity diffusion coefficient, strongly hinders practical application in high power LIBs. Herein, we report on fast storage performance hydrogenated anatase nanoparticles (H-TiO2) prepared a H2 plasma treatment. The scan-rate dependence cyclic voltammetry...
Anatase TiO2 nanosheets (ATNs) are successfully prepared by a biomimetic layer-by-layer titania mineralization approach, and the electrochemical performance of ATNs as negative electrode for lithium-ion batteries is investigated galvanostatic chronopotentiometry cyclic voltammetry. A high initial discharge capacity (311 mA h g(-1)) Coulombic efficiency (81.7%) were obtained ATNs, capacities 252, 202, 186, 158, 136, 119 g(-1) at 0.2, 1, 5, 10, 20, 30 C, respectively. Particularly, can still...
The purpose of this work was to fabricate high-performance dielectric materials for electrorheological (ER) application and electromagnetic (EM) wave attenuation. Commercial MoS2 bulks were exfoliated into nanosheets via combination ball-milling bath sonication procedures, which used as the template in situ grafting PANI nanoneedles (PANI-NDs) afford MoS2/PANI-NDs. length–diameter (L/D) ratio PANI-NDs on feasibly tuned modulating polymerization time. Therefore, tunable electrical...
The molecular mechanisms underlying the regulation of pluripotency by cellular metabolism in human embryonic stem cells (hESCs) are not fully understood. We found that high levels glutamine essential to prevent degradation OCT4, a key transcription factor regulating hESC pluripotency. Glutamine withdrawal depletes endogenous antioxidant glutathione (GSH), which results oxidation OCT4 cysteine residues required for its DNA binding and enhanced degradation. emergence OCT4(lo) cell population...
Abstract Nanosecond pulsed laser processing is an efficient method of carbon fiber reinforced plastic(CFRP), which widely used in the manufacturing field aviation, medical, and auto industries. The anisotropic heat transfer a key factor degrading surface integrity CFRP. So it urgent to explore significant mechanism interacting with A novel numerical model considering was established analyze thermal damage CFRP machining. By comparison simulation experiments, average error ablation depth...
A new class of poly-N-vinylpyrrolidinones containing an asymmetric center at C5 the pyrrolidinone ring were synthesized from l-amino acids. The polymers, particularly 17, used to stabilize nanoclusters such as Pd/Au for catalytic oxidations 1,3- and 1,2-cycloalkanediols alkenes, Cu/Au was C-H oxidation cycloalkanes. It found that bulkier substituent in ring, greater optical yields produced. Both oxidative kinetic resolution (±)-1,3- 1,2-trans-cycloalkanediols desymmetrization meso cis-diols...
In this work, we report the first use of a salen-based hypercrosslinked polymer-supported Pd catalyst to carry out C-H halogenation. This can effectively catalyze bromination and chlorination even better than its homogeneous counterpart Pd(OAc)2. It also showed excellent reusability without loss catalytic activity for ten cycles. A broad substrate scope was explored moderate yields were obtained.
Herein we report the development of an automated deoxygenative C(sp2)-C(sp3) coupling aryl bromide with alcohols to enable parallel medicinal chemistry. Alcohols are among most diverse and abundant building blocks, but their usage as alkyl precursors has been limited. Although metallaphotoredox is becoming a promising strategy form bond, reaction setup limits its widespread application in library synthesis. To achieve high throughput consistency, workflow involving solid-dosing...
Through an aqueous, protein-mediated layer-by-layer titania deposition process, we have fabricated a protamine/titania composite layer on nickel foam. The coating was composed of amorphous carbon and TiO2(B)/anatase nanoparticles formed upon organic pyrolysis under reducing atmosphere (5% H2–Ar mixture). X-ray diffraction analyses, Auger electron spectroscopy, high-resolution transmission microscopy revealed that the obtained coatings contained fine monoclinic TiO2(B) anatase nanocrystals,...
The genetic modification of plant cell walls has been considered to reduce lignocellulose recalcitrance in bioenergy crops. As a result, it is important develop precise and rapid assay for the major wall polymer features that affect biomass saccharification large population transgenic plants. In this study, we collected total 246 rice plants that, respectively, over-expressed RNAi silenced 12 genes OsGH9 OsGH10 family are closely associated with cellulose hemicellulose modification. We...
A fast and novel sample preparation procedure: ultrasound assisted ionic liquid (IL) dispersive extraction for the concentration of lovastatin simvastatin in aqueous samples was developed.
