Transition metal sulfides have a great potential for energy storage due to the pronouncedly higher capacity (owing to conversion to metal or even alloy) than traditional insertion electrode materials. However, the poor cycling stability still limits the development and application in lithium and sodium ion batteries.…
The breeding blanket with integrated first wall (FW) is the key nuclear component for power extraction, tritium fuel sustainability, and radiation shielding in fusion reactors. The ITER device will address plasma burn physics and plasma support technology, but it does not have a breeding blanket. Current activities to…
The introduction of a mobile and polarized organic moiety as a cation in 3D lead-iodide perovskites brings fascinating optoelectronic properties to these materials. The extent and the time scales of the orientational mobility of the organic cation and the molecular mechanism behind its motion remain unclear, with diff…
In heterogeneous catalysis, supports play a crucial role in modulating the geometric and electronic structure of the active metal phase for optimizing the catalytic performance. A γ-Al2O3 nanosheet that contains 27% pentacoordinate Al(3+) sites can nicely disperse and stabilize raft-like Pt-Sn clusters as a result of…
The ethanol oxidation reaction (EOR) has drawn increasing interest in electrocatalysis and fuel cells by considering that ethanol as a biomass fuel has advantages of low toxicity, renewability, and a high theoretical energy density compared to methanol. Since EOR is a complex multiple-electron process involving variou…
Single crystals of hybrid perovskites have shown remarkably improved physical properties compared to their polycrystalline film counterparts, underscoring their importance in the further development of advanced semiconductor devices. Here we present a new method of growing sizable CH3NH3PbCl3 single crystals based on…
Homologous series RO-C 6 H 4 -CH=CH-COO-C 6 H 4 -CO-CH=CH-C 6 H 4 -OC 14 H 29 (P) of chalconyl novel derivatives have been synthesized and studied with a views to understand and establish the relation between molecular structure and the liquid crystal (LC) properties of thermotropic mesomorphs Series consists of thirt…
Poly(N-vinylcarbazole) covalently grafted zinc oxide nanoparticles (ZnO-g-PNVC) were synthesized with a simple route using surface initiated reversible addition-fragmentation chain transfer (RAFT) polymerization. Initially, the surface of ZnO nanoparticles was modified by the condensation reaction of 3-chloropropyltri…
Synthesis of silver micro- and nano-particles for the preparation of conductive pastes for the metallization of solar cells was realized by chemical reduction in the presence and absence of poly(vinyl-pyrrolidone) (PVP). Silver nitrate was used as a precursor in the presence of three polyols (ethylene glycol, di-ethyl…
For applications in the field of optoelectronics, zinc oxide (ZnO) based transparent conducting oxide thin films such as aluminium-doped zinc oxide (AZO) have recently received much attention. It is one of the most promising alternative materials to the widely used indium tin oxide (ITO or tin-doped indium oxide) and…
Monolayer molybdenum disulfide (MoS2) is an emerging two-dimensional material beyond graphene, which could potentially be applicable to lightweight, flexible optoelectronic device. In this study, we have demonstrated a planar metal-semiconductor-metal (MSM) photodetectors based on large area monolayer MoS2. The monola…
Dynamically vulcanized thermoplastic elastomers (TPVs) based on polyamide‐6 (PA‐6) and poly(epichlorohydrin‐ co ‐ethylene oxide) (ECO) and their nanocomposites were prepared via melt‐blending process. The unfilled and organoclay (OC)‐filled TPVs were characterized using X‐ray diffraction (XRD), transmission electron m…
Intestinal permeability of PAMAM dendrimers has been observed, giving rationale for their use in oral drug delivery as potential carriers of associated molecules. This study assessed the apparent permeability coefficients (Papp) of dendrimers across isolated rat intestinal regional mucosae, along with estimation of th…
The basic theory for athermal dislocation storage and work hardening is revisited. The mean free slip length is redefined enabling a straightforward geometrical interpretation that can be directly compared to the grain size. It is realized that this geometrical mean free slip length is larger than the typical grain si…
Size-controlled and ordered assemblies of artificial nanotubes are promising for practical applications; however, the supramolecular assembly of such systems remains challenging. A novel strategy is proposed that can be used to reinforce intermolecular noncovalent interactions to construct hierarchical supramolecular…
A new series of thermotropic polyazomethines (PAMs) containing flexible spacers in the main chain and side methoxy groups on the mesogenic core has been synthesised by solution polycondensation reaction of o-dianisidine with α,ω-bis(4-formylphenoxy)-alkanes. A model compound was also synthesised by condensation reacti…
