A novel dual-pH sensitive charge-reversal strategy is designed to deliver antitumor drugs targeting to tumor cells and to further promote the nuclei internalization by a stepwise response to the mildly acidic extracellular pH (≈6.5) of a tumor and endo/lysosome pH (≈5.0). Poly(L-lysine)-block-poly(L-leucine) diblock c…
A series of lanthanide metal‐organic frameworks (Ln‐MOFs) are synthesized through solvothermal conditions with 1,3‐bis(4‐carboxyphenyl)imidazolium (H2L). Owing to the lanthanide contraction effect, two different types of Ln‐MOFs, namely, {[Ln(L)2(OH)]·3H2O}n (Ln:Pr, Nd, Sm) and {[Ln(L)2(COO)(H2O)2]·H2O}n (Ln: Eu, Gd,…
Dendrite growth threatens the safety of batteries by piercing the ion-transporting separators between the cathode and anode. Finding a dendrite-suppressing material that combines high modulus and high ionic conductance has long been considered a major technological and materials science challenge. Here we demonstrate…
Development of nonnoble metal catalysts for hydrogen evolution reaction (HER) is critical to enable an efficient production of hydrogen at low cost and large scale. In this work, a novel bimetallic carbide nanostructure consisting of Mo 2 C and WC is synthesized. Based on a highly conductive WC backbone, nanosized Mo…
Methylammonium lead halide perovskite solar cells continue to excite the research community due to their rapidly increasing performance which, in large part, is due to improvements in film morphology. The next step in this progression is control of the crystal morphology which requires a better fundamental understandi…
Designing tight-binding ligands is a primary objective of small-molecule drug discovery. Over the past few decades, free-energy calculations have benefited from improved force fields and sampling algorithms, as well as the advent of low-cost parallel computing. However, it has proven to be challenging to reliably achi…
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) form…
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…
