Ordered mesoporous carbon–graphitic carbon composites prepared by the “brick and mortar” method were fluorinated using F2 and investigated as cathodes for primary lithium batteries. The resulting materials have a rich array of C–F species, as measured by XPS, which influence conduction and voltage profiles.
Hollow particle is a promising material with the special properties of low densities, thermal insulation and distinct optical activity. Due to their potential promising applications in the fields of drug delivery, catalysis and optics, a great effort has been devoted to develop new preparation methods which are collec…
A core-shell photoanode, composed of a monoclinic WO3 nanorods core encapsulated with a rutile TiO2 nanoparticles shell, reveals ~246% enhancement in power conversion efficiency due to improved current density and open circuit voltage values and longer-lived charge carriers.
Neutral poly(vinyl carbazole) (PVK) and tetraphenylethylene (TPE) molecules were assembled within the interlayers of layered double hydroxide (LDH) nanosheets to form (TPE@PVK/LDH)n ultrathin films (UTFs) by the hydrogen-bonding layer by layer assembly method. These UTFs exhibit well defined blue luminescence of TPE,…
The reaction kinetics and reversibility for hydrogen sorption were investigated for supported Mg2Cu nanoparticles on carbon. A new preparation method is proposed to synthesize the supported alloy nanoparticles. The motivation of using a support is to separate the nanoparticles to prevent sintering at elevated temperat…
A novel strategy was purposed to sustainedly deliver drug-loaded nanoparticles (NPs) to tumor sites and further enhance intracellular drug release. NPs with the ability of sequential self-gelation and self-release in response to a tumor-specific microenvironment were developed, which involved the conjugation of doxoru…
In this study, thermodynamic properties of the Mg–RE–Zn (RE = Y, La) ternary hcp phase at finite temperature have been investigated by means of first-principles calculations combined with the cluster variation method (CVM). Free energy calculation, including the configurational entropy, shows that the Mg–Y–Zn ternary…
The sculpturing effects of cetyltrimethylammonium bromide and poly(vinyl)alcohol on the shape transformation of silver nano-particles are presented. It is a simple process of recent interest for obtaining silver nano-rods, spherical and hexagonal nano-plates in the thiosulphate reduction of Ag+ ions with or without st…
Among the protein-based hydrogel-forming polymers, various salts of hyaluronic acid (HA), aka hyaluronan or sodium hyaluronate, are used to prepare tissue-engineering. HA is a natural occurring glycosaminoglycan, a polysaccharide of high molecular weight which displays interesting viscoelastic properties. Among other…
Sonoelectrochemistry is a combination of ultrasound plus electrochemical process. It appears to be an attractive option to treat the industrial wastewater. In this study, we review the several applications of this hybrid technique and their efficiencies for the treatment of a variety of industrial effluents including…
We report on the structural characterization of the mullite-type PbAl 1-x Mn x BO 4 series using neutron, synchrotron and in-house X-ray powder diffraction, Raman spectroscopy and density functional theory (DFT) calculations. The planar geometry of the BO 3 group changes only slightly over the whole composition range.…
The development of green synthesis route through biological method for the synthesis of nanoparticles using plants have received attention in the recent times as it is environment friendly and economical method. ZnS nanoparticles have been prepared using glucose both as capping agent and stabilizer. The obtained ZnS n…
We demonstrate the synthesis of silver nanoparticles by a potentially benign species of bryophilous Rhizoctonia in two different media. The first medium supports fungal growth and the up-regulation of nitrate reductase, while the second medium supports fungal growth and the repression of nitrate reductase. For both me…
The emergence of antibiotic resistance in microbial pathogens requires the identification of new antibacterial drugs. The biosynthesis of methionine is an attractive target because of its central importance in cellular metabolism. Moreover, most of the steps in methionine biosynthesis pathway are absent in mammals, lo…
There is growing interest in materials generated from coiled coil proteins for medical applications. In this study we describe controlled micellar refolding of coiled coil honeybee silk proteins using the detergent SDS. Circular dichroism and dynamic light scattering experiments demonstrate that micellar SDS promotes…
α-Silicon polyoxomolybdates in combination with an iodonium salt and/or a silane are used to generate phenyl and/or silyl radicals as well as silylium cations upon UV light irradiation. These species can initiate the radical photopolymerization of acrylates, the cationic photopolymerization of epoxides and the photopo…
A high-throughput processing-characterization method, called combinatorial substrate epitaxy (CSE), was developed that enables the investigation of epitaxial stabilization of metastable compositions in complex structures. To demonstrate the approach, we fabricated RE2Ti2O7 (RE = Dy, Gd, Sm, La) in a polymorphic struct…
We first report the formation of secondary Moiré patterns from electron Moiré fringes to characterize nanostructures in multiple domains with different orientations. The pitches and the orientations of the nanoporous alumina arrays in several domains are simultaneously measured using only one electron Moiré image.
In this study, we synthesized chitin-graft-polystyrene by graft polymerization of styrene from a chitin macroinitiator via atom transfer radical polymerization (ATRP). First, the chitin macroinitiators for ATRP were synthesized by acylation of chitin with 2-bromopropionyl bromide in 1-allyl-3-methylimidazolium bromide…
This article depicts a simple and novel approach to locate calcium deposits in bone using modified carbon dots (CDs) through fluorescence imaging. Amino-functionalized CDs along with glutamic acid, a naturally-occurring ligand for calcium ions, were conjugated onto hyaluronic acid using EDC chemistry. The ability of t…
