Monolayer transition metal dichalcogenides are materials with an atomic structure complementary to graphene but diverse properties, including direct energy bandgaps, which makes them intriguing candidates for optoelectronic devices. Various approaches have been demonstrated for the growth of molybdenum disulphide (MoS…
2D Molybdenum disulfide (MoS2 ) is a promising candidate material for high-speed and flexible optoelectronic devices, but only with low photoresponsivity. Here, a large enhancement of photocurrent response is obtained by coupling few-layer MoS2 with Au plasmonic nanostructure arrays. Au nanoparticles or nanoplates pla…
Nanostructured photonic materials enable control and manipulation of light at subwavelength scales and exhibit unique optical functionalities. In particular, plasmonic materials and metamaterials have been widely utilized to achieve spectral transmission, reflection, and absorption filters based on localized or deloca…
Surface reactions with oxygen are a fundamental cause of the degradation of phosphorene. Using first-principles calculations, we show that for each oxygen atom adsorbed onto phosphorene there is an energy release of about 2 eV. Although the most stable oxygen adsorbed forms are electrically inactive and lead only to m…
Abstract Nano-SiC/Ni composite coatings on diamond surface were fabricated using an electro-co-deposition method. SiC nanoparticles with an average size of 50 nm were suspended in the plating solution and co-deposited together with Ni on diamond surface. The weight ratio (wt.%) of nano-SiC/Ni composite coating to the…
Nuclear hormone receptors are cytoplasm-based transcription factors that bind a ligand, translate to the nucleus and initiate gene transcription in complex with a co-activator such as TIF2 (transcriptional intermediary factor 2). For structural studies the co-activator is usually mimicked by a peptide of circa 13 resi…
The present work is a comparative analysis of the properties of undoped and L-Proline doped ADP crystals. Slow evaporation solution growth technique was employed for growing undoped and L-Proline doped ADP crystals. The unit cell parameters were estimated by single crystal X-Ray diffraction analysis. The crystalline n…
Abstract Anisotropic Pr–Fe–B films with soft‐magnetic layer (Fe) and/or antiferromagnetic layer (Mn, FeMn or MnO) were prepared by direct‐current (DC) magnetron sputtering on Si (100) substrates heated at 650 °C. The influence of four types’ different structures on the magnetic properties of Pr–Fe–B films was investig…
Abstract Alloys based on the titanium–tantalum system are considered for application as high-temperature shape memory alloys due to their martensite start temperatures, which can surpass 200 °C. In the present work we study the evolution of microstructure and the influence of creep on the phase transformation behavior…
This study assessed whether more potassium (K) was required for optimal growth and grain yield of cereal crops under drought and salinity than under non-stressed conditions. In 2011, three experiments on wheat (Triticum aestivum L.) with four K rates (0, 20, 40, 80 kg K/ha), four application times (0, 5, 10, 15 weeks…
The magnetic susceptibilities of nanoparticle assemblies of two Bechgaard salts ${(\mathrm{TMTSF})}_{2}{\text{PF}}_{6}$ and ${(\mathrm{TMTSF})}_{2}{\text{ClO}}_{4}$, have been studied vs temperature and magnetic field. In the bulk these materials exhibit a spin density wave formation $({T}_{\text{SDW}}\phantom{\rule{4…
Transparent conductive aluminium doped zinc oxide (ZnO: Al, AZO) films have been prepared on glass substrate by pulsed direct current reactive magnetron sputtering at room temperature. The dependence of oxygen partial pressure on the optical, electrical and structural properties was investigated. The oxygen partial pr…
Abstract Silica‐filled rubber materials exhibit stress softening and hysteresis under cyclic loadings. These phenomena are usually associated with both the Payne and Mullins effects. To better characterize these properties, five model silicas were produced and used in industrial‐like high consistency rubber ( HCR ) fo…
Abstract The photochromism of a chromene annulated on [2.2]paracyclophane, Ac‐CPC, was investigated. Whereas the parent chromene 2,2‐diphenylbenzopyran shows photoinduced coloration only at very low temperatures, acetyl‐cyclophanochromene Ac‐CPC was found to exhibit room‐temperature photochromism. With no extended con…
The main focus of this study is to characterize the interfacial interactions between silica nanoparticles and polypropylene and to investigate how the surface properties and morphology of the silica nanoparticles affect the elastic response of the silica–polypropylene composites. The composites were prepared by melt c…
The multinucleation effect of silica nanoparticles (SiNPs) had been determined in our previous studies, but the relative mechanisms of multinucleation and how the multinucleated cells are generated were still not clear. This extensional study was conducted to investigate the mechanisms underlying the formation of mult…
Heterogeneity in dopant concentration has long been important to the electronic properties in chemically doped materials. In this work, we experimentally demonstrate that during the chemical vapor deposition process, in contrast to three-dimensional polycrystals, the substitutional nitrogen atoms avoid crystal grain b…
Calotropis procera (family: Asclepiadaceae) contains cardiac glycosides which are cytotoxic to cancer cells. The extracts of C. procera have been reported to be cytotoxic to many cancer cell lines and this is the first report against the human skin melanoma cells (SK-MEL-2). The SK-MEL-2 cells treated with C. procera…
Newly developed methods for time-resolved studies using the polychromatic and in particular the pink-Laue technique, suitable for medium and small-size unit cells typical in chemical crystallography, are reviewed. The order of the sections follows that of a typical study, starting with a description of the pink-Laue t…
Abstract A mixed lanthanide complex was synthesized hydrothermally with two kinds of organic ligands, adenine and biphenyl‐4,4′‐dicarboxylic acid, and is formulated as Ad/Tb 0.999 Eu 0.001 /BPDC (Ad = adeninate, BPDC = biphenyl‐4,4′‐dicarboxylate). The photophysical properties, especially the fluorescent sensing prope…
