Zinc sulfide (ZnS) thin films have been deposited on Si (1 0 0) substrate using ultrasonic spray pyrolysis. X-ray diffraction (XRD) analysis revealed that the films are (0 0 2) preferentially oriented with c-axis-oriented wurtzite structure. The crystallinity has been found to improve with film thickness in the 180–60…
A chemical synthesis for the cobalt pertelluride mineral mattagamite is reported. Synthetic nanocrystalline mattagamite was investigated for electrochemical water oxidation and showed catalytic activity. Electrochemical water oxidation occurred at an overpotential of 380 mV at 10 mA/cm −2 with a Tafel slope of 58 mV/d…
Halloysite nanotubes (HNTs) have been successfully modified using polyethyleneimine (PEI). HNTs and PEI-modified HNTs-filled 80/20 (wt/wt) polypropylene (PP)/acrylonitrile butadiene styrene (ABS) blends and its nanocomposites in the presence of dual compatibilizer have been prepared by melt mixing technique. The refin…
We are reporting a facile way to prepare nickel/carbon nanocomposites from wood as a novel electrode material for supercapacitors. The surface morphology and the structure of the as-prepared electrodes were studied by using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (…
A phenethyl-bridged 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide derivative (DiDOPO) was synthesized and characterized. The effects of DiDOPO on the fire resistance, thermal performances, and mechanical performances of poly(lactic acid) (PLA) were examined. PLA/10 wt % DiDOPO obtained the V-0 rating (UL-94) at t…
Abstract Amidate‐supported two‐ and three‐coordinate Ni I complexes were synthesized by reduction of the corresponding Ni II precursors. A dramatic change in binding mode is observed upon reduction from Ni II to Ni I . The Ni I derivatives include an unprecedented Ni I bis(C−H) agostic complex and a two‐coordinate Ni…
Among the different methods employed for the synthesis of nanoparticles, the biological method is most favorable and quite well established. In microorganisms, use of fungi in the biosynthesis of silver nanoparticles has a greater advantage over other microbial mediators. In this study, intracellular synthesis of silv…
The remarkable electrochemical performance of graphene-based materials has drawn a tremendous amount of attention for their application in supercapacitors. Inspired by supramolecular chemistry, the supramolecular hydrogel is prepared by linking β-cyclodextrin to graphene oxide (GO). The carbon nanoparticles-anchored g…
In this paper, we demonstrate the functionality and functionalisation of waste particles as an emulsifier for oil-in-water (o/w) and water-in-oil (w/o) emulsions. Ground coffee waste was chosen as a candidate waste material due to its naturally high content of lignin, a chemical component imparting emulsifying ability…
Ceramics and metals are two of the oldest established classes of technologically useful materials. While metals dominate engineering applications, ceramics have some attractive properties compared to metals, which make them useful for specific applications. The properties of individual ceramics and metals can vary wid…
Our understanding of charge transport across interfaces needs to be reconsidered at the nanoscale, especially for advanced optoelectronic applications. Systems based on graphene, for example, present highly nonparabolic energy dispersion, for which the Schottky equation fails. The authors formulate a Kane-Schottky sca…
Microphase separation drives the structure formation in block copolymers (BCP), and it is a promising and convenient way for the preparation of well-defined hierarchically structured materials. In this work, we focus on the synthesis of amphiphilic block copolymers, i.e., polystyrene- block -poly(2-hydroxyethyl methac…
We employ molecular simulations to show that a generic isolated macromolecule behaves as a glass-forming liquid in an extreme state of nanoconfinement. Specifically, its glass transition temperature T g is strongly suppressed with respect to a corresponding bulk-state polymer, but adsorption onto an attractive substra…
We report on light sensitive microgel particles that can change their volume reversibly in response to illumination with light of different wavelengths. To make the anionic microgels photosensitive we add surfactants with a positively charged polyamine head group and an azobenzene containing tail. Upon illumination, a…
We report the H-type supramolecular polymerization of two new hydrophobic BODIPY derivatives equipped with ester and amide linkages. Whereas the ester-containing BODIPY derivative undergoes an isodesmic supramolecular polymerization in which the monomers are parallel-oriented, the replacement of the ester by amide gro…
Despite the fact that phase-change materials are widely used for data storage, no consensus exists on the unique mechanism of their ultrafast phase change and its accompanied large and rapid optical change. By using the pump-probe observation method combining a femtosecond optical laser and an x-ray free-electron lase…
Roll-to-roll manufacturing of graphene is attractive because of its compatibility with flexible substrates and its promise of high-speed production. Several prototype roll-to-roll systems have been demonstrated, which produce large-scale graphene on polymer films for transparent conducting film applications.1-4 In spi…
Abstract The threat associated with chemical warfare agents (CWAs) motivates the development of new materials to provide enhanced protection with a reduced burden. Metal–organic frame‐works (MOFs) have recently been shown as highly effective catalysts for detoxifying CWAs, but challenges still remain for integrating M…
Organophosphates are powerful inhibitors of acetylcholinesterase, which is critical to nerve function. Despite continuous research for detecting the highly toxic organophosphates, a new and improved methodology is still needed. Herein we demonstrate simple-to-fabricate chemiresistive gas sensors using conducting-polym…
The size effect and deformation transfer of the interface between graphene and a polymer substrate are experimentally investigated. Eight composite specimens, containing polyethylene terephthalate substrate (PET) and eight different sizes of graphene, are designed. The specimens are studied by a series of experiments…
