In this work, the structural and transport properties of (Nd0.7-xLax)Sr0.3MnO3 manganites with x = 0, 0.1 and 0.2 prepared by solid state reaction route are studied. These compounds are found to be crystallized in orthorhombic structural form. The influence of La substitution in place of Nd at A-site shifts the metal…
Abstract Basic processing operations will be presented. These include diamond polishing and shaping, production of conductive pathways, micro‐ and nanostructures on the diamond surface, such as diffractive optical elements. The possibility to laser produce conductive and hollow structures in the diamond bulk, includin…
A facile synthetic strategy was implemented to obtain nanosized barium titanate ( BaTiO 3 ) powders with tetragonal structure. The nanoparticles were synthesized using solvothermal process employing diethanolamine and triethanolamine to suppress the particle growth and the as‐prepared nanopowders were characterized us…
Two enantiomeric light-driven azo molecular switches with axial chirality and extended conjugation were found to exhibit unprecedented reversible photoisomerization in both organic-solvent and liquid-crystal media only upon visible-light irradiation. When doped in an achiral liquid crystal with a different concentrati…
We report new findings on the chemical vapor deposition (CVD) of monolayer graphene with negligible defects (≥95% negligible defect-peak over 200 μm × 200 μm areas) on evaporated copper films. Compared to copper foils used in the CVD of graphene, several new unexpected results have been observed including high-quality…
The creation of smart, self-assembling materials that undergo morphological transitions in response to specific physiological environments can allow for the enhanced accumulation of imaging or drug delivery agents based on differences in diffusion kinetics. Here, we have developed a series of self-assembling peptide a…
Solution-processed thin-films of semiconducting carbon nanotubes as the channel material for flexible electronics simultaneously offers high performance, low cost, and ambient stability, which significantly outruns the organic semiconductor materials. In this work, we report the use of semiconductor-enriched carbon na…
Through a systematic structural search we found an allotrope of carbon with Cmmm symmetry which we predict to be more stable than graphite for pressures above 10 GPa. This material, which we refer to as Z-carbon, is formed by pure sp(3) bonds and it provides an explanation to several features in experimental x-ray dif…
High Resolution Image Download MS PowerPoint Slide La 0.6 Sr 0.4 CoO 3−δ (LSC) thin film cathodes synthesized by pulsed laser deposition at 450°C (LSC_450°C) and 650°C (LSC_650°C) exhibit different electrochemical performance. The origin of the differences in the oxygen reduction activity and stability of these cathod…
We push the fabrication limit of gold nanostructures to the exciting sub-nanometer regime, in which light-matter interactions have been anticipated to be strongly affected by the quantum nature of electrons in metals. Doing so allows us to (1) evaluate the validity of classical electrodynamics to describe plasmonic ef…
Four 52-metal-ion 3d-4f cluster complexes featuring a common core of Ln(42)M(10) (Ln = Gd(3+), Dy(3+); M = Co(2+/3+), Ni(2+)) were obtained through self-assembly of the metal ions templated by mixed anions (ClO(4)(-) and CO(3)(2-)). Magnetic studies revealed that the Gd(42)Co(10) and Gd(42)Ni(10) clusters exhibit the…
Equilibrium phase diagrams are calculated for a selection of two-component block copolymer architectures using self-consistent field theory (SCFT). The topology of the phase diagrams is relatively unaffected by differences in architecture, but the phase boundaries shift significantly in composition. The shifts are con…
In the last decade the use of nanomaterials has been having a great impact in biosensing. In particular, the unique properties of noble metal nanoparticles have allowed for the development of new biosensing platforms with enhanced capabilities in the specific detection of bioanalytes. Noble metal nanoparticles show un…
This study investigates the tribological behavior of a new class of silicon‐disilicide ( Si ‐( Cr , V ) Si 2 ) in situ composites which display eutectic microstructures comprising a Si matrix and reinforcing ( Cr , V ) Si 2 disilicide phase. Dry, room temperature ball‐on‐disk tests carried out at various loads ( W = 1…

The addition of ginger extract containing natural antioxidants into the edible coating sausage is expected to reduce the oxidative deter…
We propose a technique that uses an optical mask layer of a phase-change material (PCM), which is used for rewritable optical recording media, to achieve highly sensitive near-field imaging spectroscopy of single semiconductor quantum constituents at optical telecommunication wavelengths. An amorphous nanoaperture all…
The chemical transformation of benzene (C(6)H(6)) and carbon disulfide (CS(2)) binary solution under high pressure condition is investigated by means of Raman spectroscopy up to 6.8 GPa. On increasing the pressure, all the Raman bands of benzene decrease in intensity, whereas new broad bands start to be observed at 15…
In the present study a novel pseudo‐ion concept is introduced in the context of classical molecular dynamics simulation. It has been shown here that this approach can successfully predict the thermo‐physical and thermo‐mechanical properties of solid solution of two isostructural compounds. ( U 0.8 Pu 0.2 ) O 2 mixed o…
The data on X-band ferromagnetic resonance (FMR) in the half and electron-doped La0.5Ca0.5MnO3 (Ca0.5) and La0.4Ca0.6MnO3 (Ca0.6) nano-crystals and bulk ceramics are reported. The FMR data for considered nano-samples appeared to be strongly different, reflecting a difference in their magnetic/electronic order. An enha…
