Single crystalline ternary ZnS(x)Se(1-x) nanowires with uniform chemical stoichiometry and accurately controllable compositions (0≤x≤ 1) were synthesized through a simple and yet effective one-step approach with a specially designed modification. Energy-gap-tuning via compositional change was achieved for a direct ban…
Lactones have found wide applications as key molecules for the synthesis of important bioactive compounds, natural products and polymers; and represent a valuable family of synthons for various organic transformations. A series of lactones or esters are synthesized from their corresponding ketones employing Baeyer–Vil…
In this study, we present a simple yet efficient method to modify polyester electrospun fibrous scaffolds by polysaccharide–protein multilayer formation based on electrostatic interactions. Chitosan (CS) and gelatin (Gel) was selected as the polycation and polyanion, respectively, to build polyelectrolyte multilayers…
To explore the potential biological activities of transition metal-based nanoparticles (NPs), we synthesized two copper-based NPs, CuI and Cu3(PO4)2. The structural features of these NPs were determined by the X-ray diffraction (XRD), dynamic light scattering (DLS) and transmission electron microscopy (TEM). The size…
A new technique to deposit nanoparticles synthesized in reverse micellar microemulsions onto support material without agglomeration is named thermal destabilization of microemulsion. The multifaceted Pt crystals, mostly truncated octahedra, were produced inside reverse micelles with an average size of 2.5 nm and a nar…
Hydrothermally stable mesoporous aluminosilicates Al-SBA-1 with hierarchical pore structure have been successfully synthesized under alkaline condition at 120 °C by employing organic mesomorphous complexes of polyelectrolyte (poly(acrylic acid) (PAA)) and cationic surfactant (hexadecyl pyridinium chloride (CPC)) as te…
A simple method has been described for the generation of white light from cationic ionic liquid (IL) compounds 1-n-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) stabilized ZnO nanocrystals (NCs). Upon mixing of the IL with the ZnO NCs, the absorption band is red shifted from 245 nm to 285 nm which is attribu…
In this paper, we report the synthesis of spiral ZnO nanocrystals by the wet-chemical etching of pyramid ZnO nanoparticles in a solvent mixture of oleic acid (OA) and 1-octylamine. Adequate evidence demonstrates that the OA in the mixed solvent acts as the etching agent. The formation of spiral ZnO nanoparticles is du…
A series of sodium borosilicate glasses containing cesium, molybdenum, and chromium was prepared to investigate the partitioning of chromium amongst the glass and phase-separated crystalline molybdates. The precipitates were examined by (133)Cs, (23)Na, and (95)Mo MAS NMR, revealing a phase assemblage consisting of Na…
For pure Fe, solution pH effects on a pitting potential and passive film properties were examined in a borate-phosphate buffer solution using a polarization test, Mott-Schottky analysis, and a galvanostatic test. Combining the results, the relationship between the surface charge and pitting potential was presented. Pa…
A new strategy capable of detecting explosive peroxide vapor via deboronation reaction induced fluorescence quenching has been developed. Using ordered assembly arrays of ZnO nanorods as catalyzing substrates, the deboronation reaction was 42 times faster than that on quartz substrates, which resulted in a very fast r…
In this work, a flexible and freestanding Carbon Nanofiber/Cobalt hydroxide (CNF/Co(OH) 2 ) composite paper is prepared via electrospinning followed by a simple chemical precipitation method. The structure characterizations show that Co(OH) 2 particles are well dispersed on the surface of the CNF, forming a thin and f…
The polyaniline–carbon nanotube composite thin film bolometric near-infrared sensor exhibited more than a two orders of magnitude sensitivity enhancement over both the polyaniline thin film and carbon nanotube network NIR sensor. We also investigated the mechanism of the effectively enhanced sensitivity of the composi…
A highly efficient strategy for synthesizing functionalized polycarbonates was established by employing a rare-earth metal catalyst.
A dry transfer process for single-walled carbon nanotubes allows for suspended, ultraclean, and hysteresis-free nanotube field-effect transistors on micro-actuated electrodes without exposing the device die to elevated nanotube growth temperatures. Nanotubes are grown on a separate die, between the arms of a fork stru…
In this paper, a microwave-assisted synthesis method has been used to prepare highly luminescent GSH-capped Zn1−xCdxTe alloyed quantum dots, with pollutant-free sodium tellurite (Na2TeO3) as the Te source. The size and composition-dependent absorption and photoluminescence spectra of the as-prepared alloyed QDs can be…
To facilitate identification of high-pressure K-cymrite (KAlSi3O8·H2O) phase and its anhydrous form (kokchetavite) in natural rocks, we have synthesized both phases and have characterized them by micro-Raman and NMR spectroscopy. K-cymrite was synthesized at 5 GPa and 800 °C. Kokchetavite was obtained by dehydrating K…
This collaboration has recently shown that infrared excitation can drive decomposition reactions of molecules on the surface of gas-phase transition metal clusters. We describe here a significant extension of this work to the study of bimolecular reactions initiated in a similar manner. Specifically, we have observed…
Two Λ-shaped BODIPY dyes based on Tröger's base, 2,8-(6H,12H-5,11-methanodibenzo[b,f]diazocineylene)-di(4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene) (DFTMB) and 2,8-(6H,12H-5,11-methanodibenzo[b,f]diazocineylene)-di(4,4-difluoro-2,6-diethyl-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene) (DFDEB),…
Nanocrystalline double-layer film of TiO2/ZnO was prepared by pulsed laser deposition on quartz substrate and their microstructure, optical property and photocatalysis were investigated. The first/bottom ZnO layer grew on its [001] direction of the wurtzite structure, while the second/top TiO2 layer consisted of nanor…
