The Mg(NH2)2-2LiH composite is a promising hydrogen storage material due to its relatively high reversible hydrogen capacity (~5.6 wt%) and suitable thermodynamic properties that allow hydrogen sorption conducting at temperatures below 90 °C. However, the presence of a severe kinetic barrier inhibits its low-temperatu…
Close-packed arrays of ZrO2 nanocrystals (NCs) have been self-assembled from a colloidal solution in a withdrawal dip coating process. A benzyl alcohol route was used to obtain NCs of narrowly controlled size, and then the capping layer was replaced by oleate using solvothermal treatment. The oleate solubility was exp…
Reaction of the linear thorocene with NC(-), N3(-) and H(-) led to the bent derivatives [(Cot)2Th(X)](-) (X = CN, N3) and the bimetallic [{(Cot)2Th}2(μ-H)](-), whereas only [(Cot)2U(CN)](-) could be formed from (Cot)2U.
Water clusters have attracted a lot of attention as prototype systems to study hydrogen bonded molecular aggregates but also to gain deeper insights into the properties of liquid water, the solvent of life. All these studies depend on an accurate description of the atomic interactions and countless potentials have bee…
First principles calculations are performed to study the noncovalent functionalization of single-wall carbon nanotubes (SWCNTs) and boron nitride nanotubes (BNNTs) with pyrazinamide (PZA), an antitubercular chemotherapeutic, providing a detailed insight into the nanotube structure and electronic properties prior to an…
An N-methylphenanthrolinium-annelated spirooxazine derivative 2(SO) whose DNA-intercalating properties are reversibly changed by a photochromic reaction was prepared. Upon irradiation at 350 nm the spirooxazine is transformed to the corresponding photomerocyanine 2(PM) that binds to DNA. After irradiation with visible…
After microwave-induced hydrosilylation reaction with 10-undecenoic acid, luminescent porous silicon nanoparticles (LPSiNPs) showed excellent fluorescence stability under physiological conditions. Fluorescence quenching in as-prepared LPSiNPs was highly sensitive with the concentration of Cu(2+) at μmol L(-1) level, w…
Here, we report a novel three-dimensional (3D) europium-complexed reduced graphene oxide (Eu–RGO (3D)) macroassembly with a microporous structure by a facile one-pot self-assembly process under very mild conditions. Europium (Eu) ions complex well with the 3D graphene through the oxygen functional groups. Apart from t…
Invention of oxygen cylinder was one of the most important developments in the field of medical practice. Oxygen and other gases were compressed and stored at high pressure in seamless containers constructed from hand-forged steel in1880. Materials technology has continued to evolve and now medical gas cylinders are g…
This paper examines the liquid crystalline blue phases of mixtures of a readily available chiral system (consisting of cholesteryl nonanoate and cholesteryl benzoate) with various proportions of a low molecular weight and low polydispersity polymer. By observing the textures of samples using polarizing optical microsc…
We investigate the nanoscale organization of a superficially hydroxylated Al substrate and its effect on subsequent protein adsorption using atomic force microscopy (AFM). For this purpose we used a mode which allows a direct mapping of a variety of surface properties (adhesion, elasticity, dissipation, etc.) to be pr…
This work describes the preparation of luminescent, high-performance aromatic polyamides. The fluorescent behaviour was achieved by preparing a diacid monomer containing a fluorescent dipicolinic acid derivative and polymerising it with commercially available aromatic diacid and diamine monomers to give polyisophthala…
Water-metal interaction has been receiving extensive attention due to its interdisciplinary application. In this paper, on the basis of first-principle calculations and slab models, the behavior of water adsorption and dissociation on planar, stepped and blocked Ni surfaces is investigated, the effects of steps, Au an…
A nitrogen rich, p-phenylenediamine based, porous aromatic framework (NPAF) with 1790 m2 g−1 BET surface area has been synthesized by using a Yamamoto coupling technique. The NPAF has shown a hydrogen uptake of 1.87 and 0.33 wt% at 77 K per 1 atm and 298 K per 80 bar, respectively. The CO2 uptake and selectivity of th…
We developed a novel technique to synthesize nanodiamond powder through the decomposition of graphitic C 3 N 4 under high pressure and high temperature. The nanodiamond obtained by the present method is in an extremely pure form with no sp 2 carbon contaminations. Individual nanodiamond grains are very uniform in size…
The application of static high pressure provides a method for precisely controlling and investigating many fundamental and unique properties of semiconductor nanocrystals (NCs). This study systematically investigates the high-pressure photoluminescence (PL) and time-resolved carrier dynamics of thiol-capped CdTe NCs o…
Many of today's forefront materials, such as high-Tc superconductors, doped semiconductors, and colossal magnetoresistance materials, are structurally, chemically and/or electronically inhomogeneous at the nanoscale. Although inhomogeneity can degrade the utility of some materials, defects can also be advantageous. Qu…
Dropwise condensation on substrates is an important topic of interest because it plays a crucial role in many scientific applications such as heat transfer, water harvesting from the humid atmosphere, and polymer templating. We focused on droplet condensation on polymer surfaces and briefly summarized the drop condens…
The use of CO2 in reforming methane to produce the industrial feedstock syngas is an economically and environmentally attractive reaction. An alumina-supported nickel catalyst active for this reaction additionally forms filamentous carbon. The catalyst is investigated by inelastic neutron scattering as well as element…
Based on Monte Carlo and Molecular Dynamics computer simulations we investigate the aggregation patterns and dynamics of model colloidal mixtures consisting of particles with either one or two, oppositely oriented, induced dipole moments. The mixtures are confined to two spatial dimensions. Our model is inspired by re…
