Chemical reactivity of a set of reactants is determined by its potential (electronic) energy (hyper)surface. The high dimensionality of this surface renders it difficult to efficiently explore reactivity in a large reactive system. Exhaustive sampling techniques and search algorithms are not straightforward to employ…
Superior Cycling Performance of SiOx/C Composite with Arrayed Mesoporous Architecture as Anode Material for Lithium-Ion Batteries, Gao, Chunhui, Zhao, Hailei, Lv, Pengpeng, Wang, Chunmei, Wang, Jie, Zhang, Tianhou, Xia, Qing
A facile and scalable single-step approach is employed to synthesize a bulk germanium electrode, which consists of nanoscale Ge-grains in ∼5 μm porous powders. This three-dimensional Ge electrode exhibits superior specific capacity (∼1500 mA h g(-1)) and cyclic performance, attributed to its unique lithiation/delithia…
Four tetraphenyl silsesquioxane based covalent-organic frameworks (sil-COFs) have been designed under a ctn or bor net topology as high-capacity hydrogen storage materials.
Biocompatible and multifunctional nanocarriers significantly improve the therapeutic and diagnostic efficacy of the cargo molecules. Here we report a novel biocompatible apatite nanocrystal-based delivery system with in situ imaging capacity. A nanorod (40 nm × 10 nm) produced by a citrate-involved sol–gel process exp…
We investigate convolution properties and coefficients estimates for two classes of analytic functions involving the q -derivative operator defined in the open unit disc. Some of our results improve previously known results.
A solvent-template method is proposed for manufacturing ion conducting membranes (ICMs) with controlled ion transport channels (in nano-scale) for vanadium flow battery (VFB) application. As a result, the ion transport properties and single cell performance of the ICMs could be easily tuned by this method. The VFB sin…
For the broadest dissemination of solid-state dynamic nuclear polarization (ssDNP) enhanced NMR as a material characterization tool, the ability to employ generic mono-nitroxide radicals as spin probes is critical. A better understanding of the factors contributing to ssDNP efficiency is needed to rationally optimize…
(abbreviated as {Mn-CO}, pqa = (2-pyridylmethyl)(2-quinolylmethyl)amine) has been incorporated in the pores of 60 nm mesoporous Al-MCM-41 nanoparticles. Strong electrostatic interactions with the negatively charged walls of the aluminosilicate host entrap the cationic carbonyl complex in the resulting material {Mn-CO}…
Desmostachya bipinnata (L.) Stapf, Poaceae, or Kusha in Sanskrit, is a sacred grass used extensively in Indian Vedic practices. It is well known for its medicinal value and is used in traditional Indian medicine to treat microbial infection in combination with other herbs. An effort has been made to isolate and charac…
Protein aggregation, linked to many of diseases, is initiated when monomers access rogue conformations that are poised to form amyloid fibrils. We show, using simulations of src SH3 domain, that mechanical force enhances the population of the aggregation-prone (N*) states, which are rarely populated under force free n…
We report the fabrication of high-performance metal oxide thin-film transistors (TFTs) with AlO x gate dielectrics using combustion chemistry in a solution process to provide energy to convert oxide precursors into oxides at low temperatures.
Realgar is a poorly water-soluble compound that exhibits poor bioavailability. To improve this, the authors reduced the particle size of realgar to nanoscale by high-energy ball milling and optimized the preparation process under which (realgar weight 40 g, milling time 9 hours, milling speed 38 Hz, milling temperatur…
A self-cross-link strategy was adopted to form inter-protein disulfide crosslinks with albumin's own thiol groups. PTX was further entrapped non-covalently in the HSA matrix to form paclitaxel loaded HSA nanoparticles (PTX-HSA-NPs).
We introduce a deterministic procedure, named TSUNA for Temperature Shaping Using Nanoparticle Assemblies, aimed at generating arbitrary temperature distributions on the microscale. The strategy consists in (i) using an inversion algorithm to determine the exact heat source density necessary to create a desired temper…
The use of a 4-imidazole containing tripodal ligand 1,3,5-tri(1H-imidazol-4-yl)benzene (H3L) enabled isolation of two three-dimensional (3D) porous metal-organic frameworks (MOFs) [Zn(HL)] · solvent (1) and [Cd(H3L)2](ClO4)2 · 10.5H2O (2) featuring 4,4- and 3,6-connected nets related to the structures of ecl and pyrit…
Reduced graphene oxide (rGO) was investigated as a material for use in chemiresistive gas sensors. The carbon nanomaterial was transferred onto a silicon wafer with interdigital gold electrodes. Spin coating turned out to be the most reliable transfer technique, resulting in consistent rGO layers of reproducible quali…
A facile strategy for synthesis of polyaniline nanoparticles and their application for development of highly sensitive amperometric glucose biosensor is demonstrated herein.
The current work reports a type of "smart" lanthanide-based theranostic nanoprobe, NaDyF4:Yb(3+)/NaGdF4:Yb(3+),Er(3+), which is able to circumvent the up-converting poisoning effect of Dy(3+) ions to give efficient near infrared (980 nm) triggered up-conversion fluorescence, and offers not only excellent dark T2-weigh…
The extracellular matrix (ECM) of decellularized organs possesses the characteristics of the ideal tissue-engineering scaffold (i.e., histocompatibility, porosity, degradability, non-toxicity). We previously observed that the muscle acellular scaffold (MAS) is a pro-myogenic environment in vivo. In order to determine…
