In molecular dynamics simulations of soft glass-formers interacting via repulsions, we find that the glass transition temperature, dynamical heterogeneity, and glass fragility reach their maxima at the same crossover pressure, Pd. Our analysis of the zero-temperature jammed states indicates that states at Pd have the…
A spin glass state is observed in the double perovskite oxide Sr2FeCoO6 prepared through sol-gel technique. Initial structural studies using x rays reveal that the compound crystallizes in tetragonal I4/m structure with lattice parameters, a = 5.4609(2) angstrom and c = 7.7113(7) angstrom. The temperature dependent po…

In the presence of silver or gold ions, visible light irradiation (> 420 nm) induces the formation of metal nanoparticles on graphene (GO) sheets without the need of any chemical reducing reagents. GO sheets serve as not only a good substrate for dispersion of metal nanoparticles but also a self-reactive material itse…
Cage dodecaphenylsilsesquioxane (T12-Phenyl) was synthesized in a one batch, mildly basic aqueous solution under room temperature conditions using a trialkoxysilane precursor. Significant improvements in synthetic yield (>95%) were observed compared with previous reports. Kinetic studies of the hydrolysis of phenyltri…
The simple strategy of linking guanine to single-walled carbon nanotubes (CNTs) through covalent functionalization permitted generation of the alignment of the nanotubes into lozenges reminiscent of guanine quartets (G-quartets) in the presence of potassium ions as observed by atomic force microscopy.
Manipulating the shape and size of metastable semiconductor nanocrystals (NCs) is important in various applications. In this work, anisotropic tetrapod- and waterdrop-shaped MnSe NCs with wurtzite (WZ) structure have been successfully synthesized by a one-pot solvothermal approach. The morphology, size and crystal str…
We report on the fabrication and characterization of diffraction gratings based on a polymeric microstructure including a light responsive material, which enables an all-optical control of the diffraction of light. The enhanced performances of a mesogenic azo dye are combined with the outstanding properties of reconfi…
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…
