Multifunctional material brings many interesting issues because of various potential device applications. Using first principles calculations, we predict that the graphitic carbon nitride (g-C4N3) nanotubes can display multifunctional properties for both spintronics and optical device applications. Very interestingly,…
This paper reviews electron emission from negative electron affinity (NEA) diamond and gives account of the recent developments in alternatives to hydrogen‐termination for producing NEA diamond surfaces, particularly using lithium on oxygen‐terminated diamond. We discuss the background and motivation for using alkali…
The effect of carbon nanotube aspect ratio (AR) on the percolation characteristics of their polymer composites was investigated by melt blending the multi-wall carbon nanotubes (MWCNTs) with different AR with a thermoplastic elastomer. Previously, most studies reported the effect of aspect ratio of MWCNTs only in the…
Pyridoxal hydrazonato molybdenum(VI) complexes were prepared by the reaction of the corresponding hydrazone (H2L1 = pyridoxal isonicotinic acid hydrazone, H2L2 = pyridoxal benzhydrazone, H2L3 = pyridoxal 4-hydroxy benzhydrazone) and [MoO2(acac)2] under appropriate conditions. The complexes can be classified into three…
Manganese oxide/carbon nanofiber (MnOx/CNF) composites were successfully fabricated as freestanding electrodes through incorporating different manganese sources of nanostructured MnO2 or Mn(CH3COO)2·4H2O into polyacrylonitrile (PAN) solution by electrospinning and a subsequent carbonization method. The MnO2 with a rod…
Microcrystalline cellulose (MCC) was functionalized with quaternary amine groups for use as an adsorbent to remove Congo Red dye (CR) from aqueous solution. The ultrasonic pretreatment of MCC was investigated during its functionalization. Characterization was conducted using infrared spectroscopy (FT-IR), X-ray photoe…
We report here a rapid and cost-effective approach to synthesize few-layer reduced graphene oxide (FL-RGO) in graphene oxide solution using EDA as a reducing agent and a cross-linker, and where the resulting FL-RGO was characterized by means of AFM, TEM, XPS, UV–vis, and XRD spectroscopies. A mechanism for forming the…
OBJECTIVE: To study the potential of phytolatex (latex of Jatropha gossypifolia) fabricated gold nanoparticles as promising candidate in sunscreen formulations for enhancement in sun protection factor. METHODS: In this study, plant latex was used as reducing and capping agent to synthesize gold nanoparticles. Latex fa…
ABSTRACT Fourier transform infrared spectroscopy was used to detect changes or degradation in chain structure of PC/ABS specimens after being exposed to three hygrothermal conditions. The two main absorbance peaks of interest are associated with carbonyl and hydroxyl groups due to the oxidation of butadiene in the ABS…
We introduce a new fabrication technique of phosphor in glass (PiG) for light-emitting diodes (LEDs) employing the tape-casting. Through the detailed process described herein and the measurement results, it is clear that the PiG-on-glass not only share the same characteristic of those obtained from other techniques or…
In this study, we demonstrated the three-level trophic transfer of quantum dots (QDs) within the aquatic food chain. Using bioimaging, we observed QD transfer from protozoa (Astasia longa) to zooplankton (Moina macrocopa) to fish (Danio rerio). Bioimaging is an effective tool that can improve our understanding of the…
An ionic liquid monomer, 3‐methyl‐1‐[2‐(2‐methyl‐acryloxy)‐ethyl]‐imidazolium chloride, was synthesized through the quaternization of N‐methylimidazole and 2‐chloroethyl methacrylate. This ionic liquid monomer intercalated into the montmorillonite layers and subsequently copolymerized with methacrylic acid. The organi…
Adhesive forces were investigated in a computational study for the complexes of graphene with each of the four adsorbates, benzene, anthracene, pyrene, and tetracene, by using the DFT method B3LYP and the semiempirical method DFTB, together with empirical dispersion corrections. The four aromatic molecules differ in s…
Reaction between ferrocene lithium or ethynylferrocene magnesium bromide and (chloro)boronsubphthalocyanine leads to formation of ferrocene- (2) and ethynylferrocene- (3) containing subphthalocyanine dyads with a direct organometallic B-C bond. New donor-acceptor dyads were characterized using UV-vis and magnetic circ…
Numerous properties from metal nanostructures can be tuned by controlling both their size and shape. In particular, the latter is extremely important because the type of crystalline surface affects the surface electronic density. This paper describes a simple approach to the synthesis of highly-structured, anisotropic…
We demonstrate a surfactant-free, solution processing route to form three-dimensional freestanding foams of pristine single-walled carbon nanotubes (SWCNTs) and explore the diverse electrochemical energy storage applications of these materials. This route utilizes SWCNT dispersions in organic n -methylpyrrolidone solv…
Abstract A novel strategy for the synthesis of microporous crystalline titanosilicate catalyst (TS‐1) was developed based on the combination of liquid‐phase and solid‐phase transformation mechanisms. The core concept of this strategy was to crystallize the mixed precursors composed of both liquid‐phase and solid‐phase…
A ternary solid solution (1 − x )(0.88 Bi 0.5 Na 0.5 TiO 3 –0.12 BaTiO 3 )‐ x Bi ( Zn 0.5 Ti 0.5 ) O 3 ( BNBZT , BNBZT x ) was designed and fabricated using the traditional solid‐state reaction method. The temperature and composition dependence of dielectric, ferroelectric, piezoelectric, and fatigue properties were s…
Stimuli-responsive polymers have been widely studied because of their potential use in nanocarriers and nanocontainers. In this study, a smart multistimuli responsive system was prepared through a light controlled supramolecular assembly. Mono cyclodextrin substituted isobutyl polyhedral oligomeric silsesquioxane (mCP…
A series of Al2O3 supported platinum catalysts (Pt/Al2O3), were prepared by a colloid deposition route. The Pt chemical state and nanostructure over the Pt/Al2O3 catalysts were characterized after calcination treatment using X-ray photoelectron spectroscopy and transmission electron microscopy. The Pt chemical state a…
