By employing a thermal oxidation strategy, we have grown large area porous Cu2O from Cu foil. CuO nanorods are grown by heating Cu which were in turn heated in an argon atmosphere to obtain a porous Cu2O layer. The porous Cu2O layer is superhydrophobic and exhibits red luminescence. In contrast, Cu2O obtained by direc…
The local laser heat treatment of precipitation hardenable aluminum alloys enables the tailoring of the materials properties and the manufacturing of lightweight and crash-proof components for the body in white. For conventional aluminum sheet metals and profiles the formability is enhanced by an indirect approach. Th…
Supramolecular copolymerization from a mixture of comonomers with different hydrophilicities may offer an easy and convenient access to form thermoresponsive supramolecular copolymers with varied phase transition temperatures by simply varying ratios of the comonomers. Herein, supramolecular dendronized copolymers (SD…
The possibility of generating MgH(2) nanoparticles from Grignard reagents was investigated. To this aim, five Grignard compounds, i.e. di-n-butylmagnesium, tert-butylmagnesium chloride, allylmagnesium bromide, m-tolylmagnesium chloride, and methylmagnesium bromide were selected for the potential inductive effect of th…
Carbon nanoparticles were obtained at room temperature by irradiating an organogel made from a 1,8-diaryloctatetrayne derivative in chloroform. During the topochemical polymerization, the morphology of the gel changes from fibers to soluble, yellow fluorescent nanoparticles in high yield. Analyses suggest that the res…
Ionic microgels are intriguing soft and deformable colloids with an effective pair potential that crosses over from Yukawa-like at large distances to a much softer repulsive interaction at short distances. Here we report the effect of adding an anisotropic dipolar contribution to colloids with such “ultra-soft” intera…
Under ultrasonication, the production of high quality graphene layers by exfoliation of graphite was achieved via addition of tiopronin as an antioxidant.
Pronounced absorption in the visible-NIR range of 400-1300 nm is demonstrated in the Ag(2)S nanoparticles (NPs)/ZnO nanowire (NW) array. ZnO NW arrays are grown on indium tin oxide substrates using chemical bath deposition. The Ag(2)S NPs are sequentially formed on the ZnO NWs through sonochemical synthesis. Structura…
Polymer electrolytes were synthesized by two different approaches and applied to electrochromic devices based on electrodeposited tungsten oxide (WO3) or poly(3,4-ethylenedioxythiophene) (PEDOT) films as the cathode, and a Prussian blue (PB) film as the anode. The first method involved the entrapping of an ionic liqui…
Supramolecular chirality has generally been fabricated by an aggregation process of chiral building blocks. Herein, we report the fabrication of the soft chiral nanotubes by chiral self-assembly, exclusively from a novel designed achiral carboxylic-substituted bolaamphiphilic azobenzene. Based on the studies with UV-v…
We study the adsorption dynamics of N(2) on the Fe(110) surface. Classical molecular dynamics calculations are performed on top of a six-dimensional potential energy surface calculated within density functional theory. Our results show that N(2) dissociation on this surface is a highly activated process that takes pla…
Controllable crystal aggregate structures which show highly uniform crystal tubule, rod and cubic like architectures were achieved and the well-defined microrods exhibit outstanding optical waveguide properties.
This paper compares the values of the thermal and fire resistance properties of composites made using the hand layup technique. E-Glass fiber reinforced epoxy composites was fabricated by filling varying concentration of aluminum oxide (Al2O3), magnesium hydroxide(Mg(OH)2), silicon carbide (SiC), and hematite powder.…

A total of 21 isolates of Fusarium sp. were isolated from soil samples collected from an area of mangrove forest in Pichavaram, Tamil nadu, India. The isolates were isolated using soil dilution, direct isolation and debris isolation techniques. Based on identification using morphological characteristics, Fusarium oxys…
A simple method employing ionic liquid functionalization is developed to achieve the uniform decoration of reduced graphene oxide sheets with gold nanoparticles. The synthesis of ionic liquid modified graphene oxide is accomplished by covalently binding 1-(3-Aminopropyl) imidazole with GO sheets. The formation mechani…
Light is used to release a drug from a cell impermeable small molecule, uncloaking its cytotoxic effect on cancer cells.
Magnetic nanoparticle dispersions are traditionally made from superparamagnetic materials since the absence of magnetic particle–particle attraction under normal conditions (no external field) easily allows preparation of stable dispersions. For inductive heating in medicinal chemistry or material science, however, th…
Al- and In-doped CdSe nanocrystals were synthesized using a three-part core-shell synthesis. CdSe core nanocrystals were first prepared, then allowed to react with dopant precursors in the presence of weakly binding ligands, and finally overcoated with an additional shell of CdSe. The addition of Al dopants quickened…
DNA programmed nanoparticle self-assembly is emerging as a powerful technique to engineer novel materials. In this paper, we present a comprehensive characterization of the dynamics of DNA mediated nanoparticle superlattice self-assembly from numerical simulations. We show that crystallization is consistent with class…
