Abstract C 60 /polyaniline (PANI) nanocomposites have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in the presence of C 60 by using an interfacial reaction. When compared with the pure PANI nanofibers from the similar process, the diameter of the obtained C 60 /PANI nanofib…
On the basis of density functional theory calculations, the electronic and magnetic properties of graphene/fluorographene superlattices (GFSLs) are systematically investigated. Our calculations show that the electronic properties are both interface-orientation- and graphene-width-dependent. All armchair GFSLs (AGFSLs)…
The objective of this work is to access the release behavior of thymol and p -cymene used as model core materials with PLA microcapsules. The microcapsules were obtained by a coacervation process developed in a previous work and present a spherical shape with mean particle size of 25 and 37 μm for thymol and p -cymene…
State-resolved squared form factors of the electric monopolar excitations to $3{p}^{5}4p{[1/2]}_{0}$ and $3{p}^{5}4{p}^{\ensuremath{'}}{[1/2]}_{0}$, the electric dipolar excitations to $3{p}^{5}4s{[3/2]}_{1}$ and $3{p}^{5}4{s}^{\ensuremath{'}}{[1/2]}_{1}$, and the electric quadrupolar excitations to $3{p}^{5}4p{[5/2]}…
This review assesses past experiences from superheated fossil plants, supercritical fossil plants, superheated nuclear plants, and light water reactors from the late 1940s until the present. Data from the development and operation of these plants are directly applicable to supercritical water reactor (SCWR) plants bei…
The low-temperature specific heat of annealed single-crystal samples of Ba(Fe${}_{1\ensuremath{-}x}$Co${}_{x}$)${}_{2}$As${}_{2}$ with compositions spanning the entire superconducting phase diagram was measured. Effort was made to discover the best annealing schedule to maximize ${T}_{c}$ and minimize transition width…
To improve the poor color rendering index (CRI) of YAG:Ce-based white light-emitting diode (LED) due to the lack of red spectral component, core/shell/shell CdSe/CdS/ZnS quantum dots (QDs) were synthesized and blended into nano-YAG:Ce3+ phosphors. Prominent spectral evolution has been achieved by increasing the conten…
In this novel platform, a micropatterned polymer brush was obtained by grafting poly(poly(ethylene glycol) methyl ether methacrylate) (poly(PEGMA)) from a thin macroinitiator film using atom transfer radical polymerization (ATRP). A pattern of holes was formed in the macroinitiator film by taking advantage of its spon…
Photochromic molecules are part of a large class of materials in which light stimulus not only induces a color variation but also affects other physicochemical properties. However, the change of bulk electrical properties (e.g., electrical conductivity) via light excitation remains difficult to control because the int…
Two near-ultraviolet (UV) sensors based on solution-grown zinc oxide (ZnO) nanowires (NWs) which are only sensitive to photo-excitation at or below 400 nm wavelength have been fabricated and characterized. Both devices keep all processing steps, including nanowire growth, under 100 °C for compatibility with a wide var…
Water-repellent all-cellulose nanocomposite (ACNC) was made using the silane coupling agent dodecyltriethoxysilane. The ACNC, consisting of cellulose nanofibers incorporated into a cellulosic matrix, was prepared by reducing crystallinity in the surface of the cellulose nanofibers using DMAc/LiCl solvent, followed by…
Crude cellulose prepared from alkali-extracted sugarcane bagasse was subjected to a rapid purification treatment with a mixture of 80% acetic acid-68% nitric acid (10/1, v/v) at 120 C for 15 min. The yields of the preparations decreased slightly from 57.3%-58.6% in the crude cellulose preparations to 50.3%-51.9% in th…
We developed a new general approach to address individual graphene sheets in few-layer graphene by Raman spectroscopy. Our method is based on isotope labeling of individual layers during their synthesis and subsequent transfer to form multilayered graphene. The power of the procedure is demonstrated in the analysis of…
Recently, many researchers have attempted to convert soybean oil into useful polymers. One of the ways to make soybean oil into a matrix of green composites is to modify its triglyceride structure to obtain the acrylated epoxidized soybean oil (AESO) through epoxidization and acrylation. In this study, the effects of…
We report the fabrication, at low-temperature, of solution processed graphene transistors based on carefully engineered graphene/organic dielectric interfaces. Graphene transistors based on these interfaces show improved performance and reliability when compared with traditional SiO(2) based devices. The dielectric ma…
Abstract The NO 3 – ‐type Eu 3+ ‐doped layered gadolinium hydroxide (NO 3 –LGdH:Eu) was prepared by a developed homogeneous precipitation method through hexamethylenetetramine (HMT) hydrolysis with hydrothermal treatment. Two amino acid anions, phenylalanine (Phe) and tyrosine (Tyr), were intercalated into LGdH:Eu to…
In this study, we synthesized a low-molecular-weight polytyrosine (PTyr) through living ring-opening polymerization of the α-amino acid- N -carboxyanhydride and then blended it with poly(4-vinylpyridine) (P4VP) homopolymer in N, N -dimethylformamide (DMF) and MeOH solutions, thereby controlling the miscibility behavio…
Top-of-the-line corrosion (TLC) has been a serious issue for the oil and gas industry. Conventional inhibition techniques are expensive and often do not seem to provide enough protection to the steel surface at the top of the pipe. A novel idea is to inject the corrosion inhibitor within a foam matrix. The foam slug i…
The effects of partial replacement of rattan powder (RP) by carbon black (CB), mica, and calcium carbonate (CaCO 3 ) on the curing characteristics, tensile properties, rubber-filler interaction, and morphological studies of natural rubber (NR) composites were investigated. Rattan powder with an average particle size o…
Vacancy-ordered transition metal oxides have multiple similarities to classical ferroic systems including ferroelectrics and ferroelastics. The expansion coefficients for corresponding Ginzburg-Landau-type free energies are readily accessible from bulk phase diagrams. Here, we demonstrate that the gradient and interfa…
