This study evaluated the effectiveness of dimethyldiethoxysilane (DMDES) precursor in improving the elastic recovery behavior of silica aerogels reinforced with epoxy through amine sites on the silica surface. In the study, two aminosilanes – 3-aminopropyltriethoxysilane (APTES) and bis(trimethoxysilylpropyl)amine (BT…
A major challenge in single particle reconstruction from cryo-electron microscopy is to establish a reliable ab initio three-dimensional model using two-dimensional projection images with unknown orientations. Common-lines--based methods estimate the orientations without additional geometric information. However, such…
Two new triindole-cored star-shaped molecules SM-1 and SM-2 have been designed and synthesized, and their optical, electrochemical, thermal, transport and photovoltaic properties have been investigated in detail. SM-1 and SM-2 exhibited good thermal stability, intensive absorption in a broad region, and relatively hig…
In this study, Zn2GeO4 hollow spheres were successfully fabricated by a template-engaged approach using zinc hydroxide carbonate (Zn4CO3(OH)6·H2O, ZHC) spheres as the template. During the hydrothermal process, Zn(2+) dissolved from the surface of the ZHC spheres could rapidly react with the HGeO3(-) in solution and th…
The CO2 capture performance of four zeolitic imidazolate frameworks (ZIFs), ZIF-10, ZIF-71, ZIF-68 and ZIF-69, was investigated in the presence of SO2 using molecular simulations. Our results show that SO2 is preferentially adsorbed over CO2. However, it also shows a cooperative effect on CO2 adsorption. In ZIF-10 and…
Aptides, developed by our laboratory, are a novel class of high-affinity peptides. Here, we describe the conjugation of an aptide targeting extra-domain B (EDB) of tumor-associated fibronectin to drug-containing liposomes and explore the potential of these aptide-conjugated liposomes as a robust and efficient targeted…
Reduction of [U(Ts(Tol))(Cl)(μ-Cl)U(Ts(Tol))(THF)2] [2, Ts(Tol) = HC(SiMe2NAr')3; Ar' = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(Ts(Tol))}2(μ-η(6):η(6)-C6H5Me)] (3); combined structural, spectroscopic, magnetic, and computational analyses unambiguously confirm that the uraniu…
P-glycoprotein (P-gp), an ATP-binding cassette, is able to transport structurally and chemically unrelated substrates. Over-expression of P-gp in cancer cells significantly decreases the intercellular amount of anticancer drugs, and results in multidrug resistance in cancer cells, a major obstacle in cancer chemothera…
Abstract New reagent, N,N,N′,N′,N′′,N′′-hexaoctylnitrilotriacetamide (NTAamide(C8)), was synthesized and examined for actinoid and lanthanoid extractions. NTAamide(C8) has one N atom and three carbonyl oxygen atoms in the central frame, and may show hybrid bonds between hard O and soft N donors. It was found that NTAa…
Structurally colored fiber was fabricated by an electrophoretic deposition method under a circinate electric field. These fibers exhibit structural color, based on the external field-assembly of charged PMMA microspheres on the surface of the electroconductive carbon fiber, with reflectance spectra stretch-tunable in…
Two donor–acceptor (D–A) polyazothines (PAs), incorporating the oxadiazole entity either acting as an electron acceptor (A) to form D–A structured PA-1 with the triphenylamine donor (D), or acting as a donor to form D–A structured PA-2 with the 3,3′-dinitro-diphenylsulfone acceptor, have been successfully synthesized…
Synthesis of 5-hydroxymethylfurfural (5-HMF) from biomass derived mono- and poly-saccharides is gaining importance because of its usefulness in the preparation of important chemicals. In our work, we have synthesized several silicoaluminophosphate (SAPO) catalysts, and have shown that in the absence of any other pH mo…
The importance of the acidity and mesoporous structure to the hydrodeoxygenation activity of catalysts for bio-oil upgrading was investigated. By testing three model bio-oil compounds, we showed that catalysts with a strong acidity (e.g. ZSM-5) have a high hydrodeoxygenation activity, while the mesoporous structure of…
Two efficient blue-light-emitting compounds, 1,8-bis(4-(N-carbazolyl)phenyl)naphthalene (BCzPN) and 1,8-bis(4-(10-phenylanthracen-9-yl)-phenyl)naphthalene (BPAPN), are designed and synthesized, in which two phenylcarbazole or diphenylanthracene units are closely stacked through bonding to the 1- and 8-positions of the…
Ceria (CeO2) nanorods with well-defined surface planes can be synthesized and utilized for the hydrogenation of nitroaromatics. The CeO2 nanorods containing a {110} plane can efficiently and selectively catalyse the hydrogenation of nitroaromatics with N2H4 as a reducing agent, while nano-ceria with a {100} or {111} p…
Formation of deposits on heat exchanger surfaces during operation rapidly increases the thermal resistance and reduces the operating service life. Product quality is deteriorated by fouling, which causes reduction of proper heating. The chemistry of fouling from milk fluids is qualitatively understood, and mathematica…
ZnO photonic crystals (ZnO-PCs) with large area and high quality were prepared by a facile auto-forced impregnation method. The resulting ZnO-PCs exhibited remarkable photocatalytic performance and photocorrosion inhibition compared with porous and commercial nanoparticle ZnO.
A novel approach was developed to achieve three-dimensional macroporous NiO/Ni powders. The unique architecture, together with the highly distributed Ni additive ensures the remarkably enhanced discharge capacity, initial coulombic efficiency, cycling stability, and rate capability when utilized as anodes in lithium-i…
BACKGROUND: Pretreatment of lignocellulosic biomass is a prerequisite for effective saccharification to produce fermentable sugars. In this study, "green" solvent systems based on acidified mixtures of glycerol carbonate (GC) and glycerol were used to treat sugarcane bagasse and the roles of each solvent in deconstruc…
The use of tetrakis-(hydroxymethyl)-phosphonium chloride (THPC) as simultaneous reducing agent and stabilizing ligand has been extended to the single-step synthesis at room temperature of a wide variety of monometallic nanoparticles and bi-/tri- metallic nanoalloys containing noble metals with potential application in…
