Etched multiwalled carbon nanotube (EMCNT) was prepared via an in situ reaction between Si and MCNT induced by the reaction between Na and I2. Subsequently, EMCNTs was subjected to a copolymerization reaction with 4,6-diaminoresorcinol salt (DAR2HCl) and terephthalic acid (TA) in polyphosphoric acid (PPA) by Friedel–C…
A variety of technological applications related to oxide semiconductor-based devices have attracted great interest among the scientific community, leading to an increase in studies of these materials during the last years. Among such materials, zinc oxide (ZnO) has applications in several areas, from light-emitting di…
The Inside Cover picture shows an amine-tethered porous polymer network and its application for carbon capture from flue gas. This polymer based on diethylenetriamine, PPN-125-DETA, exhibits a working capacity comparable to industrial benchmark monoethanolamine (MEA) solutions. More importantly, the energy cost for th…
Based on the Cluster Perturbation solution of the Hubbard hamiltonian for a 2-D honeycomb lattice we present quasiparticle band structures of nanoribbons at half filling as a function of the on-site electron-electron repulsion.We show that, at moderate values of e-e interaction, ribbons with armchair-shaped edges exhi…
We report on the simultaneous realization of p-type conductivity and strong ferromagnetism in heavily Co-doped ZnO thin films in the presence of a high concentration of hydrogen impurities. Through ab initio calculations, we find that the microscopic origin of hole carrier generations and ferromagnetic ordering is due…
Although the ambiguity of the crystal structures determined directly from diffraction intensities has been historically recognized, it is not well understood in quantitative terms. Bernstein's theorem has recently been used to obtain the number of one-dimensional crystal structures of equal point atoms, given a minimu…
Chemical vapor deposition processes to create magnesium diboride (MgB2) nanowires, a well-known superconductor, and orthorhombic boron nanorods are reported. These boron nanorods are doped with magnesium and sulfur, and the doping induces a number of defects in the material. The synthesis technique used to create thes…
Magnetization reversal behavior of GaMnAs film grown on Si substrate investigated by planar Hall measurements, Lee, Sangyeop, Won, Jaehyuk, Shin, Jinsik, Lee, Hakjoon, Yoo, Taehee, Lee, Sanghoon, Liu, Xinyu, Furdyna, Jacek K.
The applications of anomalous scattering for locating metal atoms and discriminating between different elements has increased when optimised with synchrotron X-radiation. A distinct trend now is the introduction of in vacuum diffractometers to serve both the life and physical sciences. Examples of applications are giv…
Using resonant x-ray scattering at the Mn K-edge, we have investigated the nature of the charge and lattice modulation in the La 1-x Sr 1+x MnO 4 (x=0.5 and 0.6) manganites. Resonant reflections ( h ±ε, h ±ε, 0) and ( h ±2ε, h ±2ε, 0) of the tetragonal I4/mmm structure with a modulation vector of 2e=l-x were found in…
Abstract Mesostructured TiO2 nanomaterials with tuned crystallite sizes were elaborated by a novel green route using soluble starch as the structuring agent and titanium(IV) isopropoxide as the inorganic precursor. Using hydrothermal treatment (HT), soluble-starch removal from the inorganic matrix is about 80 wt % aga…
Ring-spun yarn is still considered by most producers of yarn to have ideal structure and parameters. This preference is confirmed by end-textile-product manufacturers because of the overall balance among the various aspects that determine yarn quality, making ring-spun yarns the yarns of choice for most applications.…
Corn and native cassava starch were modified by oxidation and acid hydrolysis, aiming to develop paper and paperboard stickers. The oxidation was made with Sodium hypochlorite (NaOCl) in two distinct concentrations of active chloride which is present on oxidizing agent solution. The synthesis resulting products were u…
Put it simply, batteries are devices that can convert chemical energy into electricity by the oxidation or reduction of active species. This process is reversible such that the system can be used for both energy storage and electricity delivery. Normally, batteries from different active species could meet specic EES a…
As supplies of fossil fuels dwindle and the global warming crisis increases, there is a strong demand for new energy from renewable sources with minimal negative environmental impact. Signicant efforts have been devoted to develop alternative electricity production methods, such as solar, geothermal, wind, nuclear and…
In this paper, we have analyzed the well-known quasielastic scattering data at 29 MeV/nucleon of the $^{11}\mathrm{Li}$ + $^{28}\mathrm{Si}$ system within the framework of the coupled-channels model using double-folding potential with a Woods-Saxon type of imaginary part. To explain these challenging data, we have mod…
As semiconductor devices are being increasingly scaled down, complex and high-aspect-ratio (AR) structures become necessary. The spin-on-glass (SOG) method has been considered to be effective for filling high-AR (>50) structures, because it enables low-cost fabrication and it has greater amenability to such structures…
p-Hydroxybenzaldehyde–biuret–formaldehyde (p-HBBF) copolymer resin was synthesized through the condensation of p-hydroxybenzaldehyde and biuret with formaldehyde in the presence of hydrochloric acid as a catalyst and with various molar ratios of the reacting monomers. The resulting copolymer was characterized with UV-…
The novel porous octahedral Cu microcrystals were synthesized successfully by a simple one‐step hydrothermal reduction method based on TEA technique. The X‐ray diffraction (XRD) patterns reveal that Cu microcrystals have octahedral crystalline phase and high purity. Scanning electron microscopy (SEM) and transmission…
Three physical properties of the supersaturated vanadium (II) and vanadium (III) sulphate solutions were investigated in this study: density, viscosity and conductivity. These solutions correspond to the charged and discharged negative half-cell electrolytes, respectively, of the vanadium redox ow battery (VRFB) and t…
