Synthesis and characterization of YAG:Ce phosphors for white LEDs
Abstract Worldwide commercial interest in the production of cerium doped yttrium aluminium garnet (YAG:Ce) phosphors is reflected in the widespread use of white light emitting devices. Despite of the fact that YAG:Ce is considered a “cool phosphor” it is the most important in white LED technology. This article reviews…
An electrospun lignin/polyacrylonitrile nonwoven composite separator with high porosity and thermal stability for lithium-ion batteries
In this work, lignin/polyacrylonitrile composite fiber-based nonwoven membranes (L–PANs) were prepared by electrospinning with dispersing different amounts of lignin in the polyacrylonitrile (PAN) solutions.
Biological Synthesis of Silver Nanoparticles by Cell-Free Extract ofSpirulina platensis
The present study explores biological synthesis of silver nanoparticles (AgNPs) using the cell-free extract ofSpirulina platensis. Biosynthesised AgNPs were characterised by UV-Vis spectroscopy, SEM, TEM, and FTIR analysis and finally evaluated for antibacterial activity. Extracellular synthesis using aqueous extract…
Tuning thermal conductivity of crystalline polymer nanofibers by interchain hydrogen bonding
Interchain hydrogen bonds enhance thermal conduction in crystalline polymer nanofibers by confining torsional motion of polymer chains and by increasing the group velocity of phonons.
Stabilizing volatile liquid chemicals using co-crystallization
A convenient, effective, and scalable protocol for stabilizing volatile liquid chemicals is reported. Through the use of halogen-bond driven co-crystal synthesis, several examples of liquid iodoperfluoroalkanes are transformed into crystalline materials with low-vapor pressure, considerable thermal stability, and mois…
An additional fluorenylmethoxycarbonyl (Fmoc) moiety in di-Fmoc-functionalized l -lysine induces pH-controlled ambidextrous gelation with significant advantages
In recent years, several fluorenylmethoxycarbonyl (Fmoc)-functionalized amino acids and peptides have been used to construct hydrogels, which find a wide range of applications. Although several hydrogels have been prepared from mono Fmoc-functionalized amino acids, herein, we demonstrate the importance of an additiona…
VO 2 nanorods for efficient performance in thermal fluids and sensors
VO2 (B) nanorods with average width ranging between 50-100 nm are synthesized via a hydrothermal method and the post hydrothermal treatment drying temperature is found to be influential in their overall phase and growth morphology evolution. The nanorods with unusually high optical bandgap for a VO2 material are effec…
Effect of PEG Pairing on the Efficiency of Cancer-Targeting Liposomes
Standardized poly(ethylene glycol)-modified (PEGylated) liposomes, which have been widely used in research as well as in pre-clinical and clinical studies, are typically constructed using PEG with a molecular weight of 2000 Da (PEG(2000)). Targeting ligands are also generally conjugated using various functionalized PE…
Synergistic effect of PLA–PBAT–PLA tri-block copolymers with two molecular weights as compatibilizers on the mechanical and rheological properties of PLA/PBAT blends
Systematic study on the synergistic effects of different molecular-weight PLA–PBAT–PLA tri-block copolymers on the mechanical and rheological properties of PLA/PBAT blends.
A self-assembled nanotube for the direct aldol reaction in water
Nanotubes formed by the aqueous assembly of a proline-lysine dipeptide (1) were used to create the hydrophobic microenvironments required to catalyze the aldol reaction in water. The self-assembly process occurred most efficiently in the presence of the substrates, producing an array of homogeneous nanotubes under the…
Biological and environmental media control oxide nanoparticle surface composition: the roles of biological components (proteins and amino acids), inorganic oxyanions and humic acid
Evolution of nanoparticle surface composition in increasingly complex biological and environmental matrices.
Physical, Mechanical, and Morphological Properties of Woven Kenaf/Polymer Composites Produced Using a Vacuum Infusion Technique
Nowadays, due to renewable issues, environmental concerns, and the financial problems of synthetic fibres, the development of high-performance engineering products made from natural resources is increasing all over the world. Lately, kenaf fibre has been used among many different types of natural resources in various…
Role of surface defects on visible light enabled plasmonic photocatalysis in Au–ZnO nanocatalysts
Visible light photocatalytic activity of the plasmonic gold–zinc oxide (Au–ZnO) nanorods (NRs) is investigated with respect to the surface defects of the ZnO NRs, controlled by annealing the NRs in ambient at different temperatures.
The electronic and optical properties of MoS 2(1−x) Se 2x and MoS 2(1−x) Te 2x monolayers
In a very recent article, atomically thin two-dimensional MoS2xSe2(1-x) nanosheets have been synthesized with complete composition tunability using a temperature gradient assisted chemical vapor deposition technique [J. Am. Chem. Soc., 2014, 136, 3756]. To have a better understanding of the composition dependent tunab…
Novel environmentally sustainable cardanol-based plasticizer covalently bound to PVC via click chemistry: synthesis and properties
Cardanol, a famous renewable organic resource of the cashew industry, was covalently linked to PVC chains as a natural internal plasticizer using the click reaction. The modified PVC exhibited decreased T g and near-zero migration.

Polyaniline–ruthenium oxide (PANI–RuO 2 ) composite thin films prepared by a chemical bath deposition (CBD) method for supercapacitor application.
On the structural landscape in endohedral silicon and germanium clusters, M@Si 12 and M@Ge 12
Amongst the endohedral clusters of the tetrel elements, M@En, the 12-vertex species are unique in that three completely different geometries, the icosahedron (Ih, [Ni@Pb12](2-)), the hexagonal prism (HP, Cr@Si12) and the bicapped pentagonal prism (BPP, [Ru@Ge12](3-)) have been identified in stable molecules. We explor…
Oxygen diffusion in single crystal barium titanate
Oxygen diffusion in cubic, nominally undoped, (100) oriented BaTiO3 single crystals has been studied by means of (18)O2/(16)O2 isotope exchange annealing and subsequent determination of the isotope profiles in the solid by time-of-flight secondary ion mass spectrometry (ToF-SIMS). Experiments were carried out as a fun…
