Post-synthetic covalent modification of the metal-organic framework IRMOF-3 amino group with pentane-2,4-dione and 3-(2-hydroxyphenyl)-3-oxopropanal followed by the coordination of Nd(3+)/Y(3+) allows the design of near-infrared light-emitting materials.
Over the last decade, polymer solar cells (PSCs) have attracted a lot of attention and highest power conversion efficiencies (PCE) are now close to 10%. Here we employ an optical structure - the microlens array (MLA) - to increase light absorption inside the active layer, and PCE of PSCs increased even for optimized d…
Nanogranular Al2O3 films were deposited by the plasma-enhanced chemical vapor deposition (PECVD) method using gas sources of trimethylaluminum and oxygen at 100 °C. Structural characterizations indicate that the as-deposited nanogranular Al2O3 film has an amorphous structure with excess oxygen due to ambient humidity…
Reactions of the β-diketiminato (‘Nacnac’) stabilized gallium dihydride H2Ga{(NDippCMe)2CH} with a range of mono- and dinuclear metal carbonyl reagents are characterized by loss of dihydrogen and formation of donor/acceptor complexes featuring the Ga(I) carbenoid ligand : Ga{(NDippCMe)2CH}. Thus, far from simply mimic…
In this contribution we report on results from an optimization study of SU-8 photoresist derived carbon electrodes. SU-8 derived carbon tends to be glassy in nature, however, based on the exact pyrolysis strategy and other fabrication parameters employed one can obtain a range of electrical, electrochemical and therma…
Ru/AC catalysts with K promoter were prepared by impregnation of the samples with different amounts of KOH. The catalysts were characterized using a variety of techniques, including X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, CO chemisorption and temperature-programmed desorp…
A novel nanocomposite architecture of a Fe2O3-SnO2-C anode, based on clusters of Fe2O3 and SnO2 nanoparticles dispersed along the conductive chains of Super P Li™ carbon black (Timcal Ltd.), is presented as a breathable structure in this paper for lithium-ion batteries. The synthesis of the nanocomposite is achieved b…
The effort to stabilize enzymes and improve their activity has generated great interest because of their wide application in proteomics research, bioenergy conversion, bioassays and so on. In this work, biocompatible reactive polymer, poly (glycidyl methacrylate), grafted from magnetic nanoparticles by atom transfer r…
We report a reliable and effective strategy to synthesize magnetically recyclable Bi2WO6 microspheres using Fe3O4 nanoparticles as supports. The as-prepared hierarchical photocatalyst displays excellent photocatalytic activity and reusability under visible light irradiation.
We present a metal carbide clusterfullerene Sc2C2@Cs(10528)-C72, whose structure has been baffling for many years. A motional endohedral Sc2C2 cluster, special molecule geometry and electronic structure were found in Sc2C2@Cs(10528)-C72. The paramagnetic Sc2C2@Cs-C72 anion radical was successfully prepared by a chemic…
A host material with a high triplet excited-state energy level and a deep HOMO energy level has been developed by directly linking the donor and acceptor units through a phosphinic amide. Phosphorescent organic light-emitting diodes containing this material and a deep-blue dopant achieved an external quantum efficienc…
Although rapid progress has been made in understanding the interaction of nanoparticles (NPs) with lipid membrane, little is known about the interaction between neighboring NPs on the membrane. With the aid of computer simulation techniques, in this work we systematically investigate the membrane mediated interaction…
We report an innovative approach for miRNA-203 delivery in esophageal cancer cells using protamine sulphate (PS)-nanodiamond (ND) nanoparticles. The efficient delivery of miR-203 significantly suppressed the proliferation and migration of cancer cells through targeting Ran and ΔNp63, exhibiting a great potential for P…
We report the preparation and characterization of amorphous silicon-carbon (Si-C) nanospheres as anode materials in Li-ion batteries. These nanospheres were synthesized by a chemical vapor deposition at 900 °C using methyltrichlorosilane (CH3SiCl3) as both the Si and C precursor, which is a cheap byproduct in the orga…
We introduced a minimal model of the donor-acceptor interface encountered in organic solar cells to explain the efficient generation of free charges in these systems and we investigated the nature of charge transfer states formed by a delocalized exciton in the donor component. Contrarily to the generally accepted vie…
A comprehensive spectral and photophysical investigation of four donor-acceptor-donor (DAD) oligomers consisting of electron-deficient 2,1,3-benzothiadiazole or quinoxaline moieties linked to electron-rich thienyl or bithienyl units has been undertaken. Additionally, a bis(dithienyl) substituted naphthalene was also i…
Halogen bond (X-bond) interactions involving organic iodine have been investigated using data retrieved from the Cambridge Structural Database (CSD) and Density Functional Theory (DFT) calculations. The analysis of the mean normalised intermolecular distances involving Csp–I, Csp2–I and Csp3–I X-bond donors first show…
The VB energy level of TiO2−xNx can be fine tuned in a wide range by controlling the N content, which realized a high selectivity for the photocatalytic oxidation of alcohols into aldehydes in aqueous solution under visible light irradiation.
A scalable method to load a cobalt-oxide-phosphate (CoPi) water oxidation electrocatalyst onto the surface of a mesoporous graphitic-carbon-nitride (mpg-CNx) semiconductor is reported. This procedure resulted in significant enhancement of photocatalytic activity of the mpg-CNx in water oxidation. The optimal loading g…
BACKGROUND: The investigation of structural organisation in lignocellulose materials is important to understand changes in cellulase accessibility and reactivity resulting from hydrothermal deconstruction, to allow development of strategies to maximise bioethanol process efficiencies. To achieve progress, wheat straw…
