Recent plasma-material-interaction (PMI) studies of relevance to fusion PMI science are discussed. The results are a mix of science experiments and in situ diagnostic technology development. Scientific issues addressed include the nature of He and W atom migration in the evolution of W fuzz surfaces, understanding the…
In an attempt to improve the dielectric behavior of NiO nanoparticles, pure and 2% Sm doped NiO nanoparticles were prepared via co-precipitation method. The prepared samples were characterized by x-ray Powder Diffraction XRD and Transmission Electron Microscopy TEM. The XRD results confirm the formation of the NiO cub…
Sol-gel synthesis of copper (II) oxide/alginate (CuO/Alg) bio-nanocomposite and effects of rapid thermal annealing on its properties and structure, Siddiqui, Vasi Uddin, Ansari, Afzal, Khan, Imran, Akram, M Khursheed, Siddiqi, Weqar Ahmad
The microstructure and biodegradability of a near β Ti-25Nb-3Zr-3Mo-2Sn alloy produced by laser engineered net shaping have been compared to those of alloys produced via casting and cold rolling in order to identify the key effects of processing pathways on the development of microstructure and biocorrosion properties…
Solubility of phenylphosphonic acid (PPOA) in 15 solvents (methanol, ethanol, n -propanol, isopropyl alcohol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol, 1-octanol, 2-methoxyethanol, 2-ethoxyethanol, 2-propoxyethanol, 2-butoxyethanol, acetone, and 1,4-dioxane) was measured by the isothermal saturation method under 0…
La1-xCexFeO3; 0 ≤ × ≤ 0.15 nanoparticles were prepared in single phase using flash combustion technique. The crystalline structure and morphology of the investigated samples were researched through XRD and HRTEM. As a result, the dielectric constant of LaFeO3 was enhanced by Ce3+ ion substitution due to some the Ce3+…
We have developed a new synthetic strategy for the preparation of a series of isoindolin-1-imines and isoindolin-1-ones from aromatic ketones and phthalonitrile. Self-condensation reactions of these isoindolin-1-imines led to the formation of a novel class of benzo-fused, highly electron-deficient core-extended azadip…
Abstract Dry reforming of methane (DRM) is one of the most attractive chemical reactions, since it converts global‐warming gases into valuable syngas including hydrogen and carbon monoxide. Numerous previous studies used metal oxides catalysis supports, such as Al2O3, but their operating temperature was very high and…
This work reports the coprecipitation synthesis and characterization of single-phase Sm 3+ /Sr 2+ /Ca 2+ codoped with Gd 3+ in cerium oxide formulated as Ce 0.8 M 0.1 Gd 0.1 O 2−δ (CMGO; M = Sm 3+, Sr 2+, Ca 2 ) nanopowder and their nanocomposites with sodium carbonate formulated as Ce 0.8 M 0.1 Gd 0.1 O 2−δ –Na 2 CO…
We contrast the generic features of structural relaxation close to the idealized glass transition that are predicted by the self-consistent generalized Langevin equation theory (SCGLE) against those that are predicted by the mode-coupling theory of the glass transition (MCT). We present an asymptotic solution close to…
Abstract Nowadays, weight reduction and efficiency improvement in different parts of airplanes are the most challenging issues of engineering which are being overcome by new approaches like the employment of modern sciences namely smart materials. The research on enhancement of lift coefficient of the aircraft’s wing…
Two new sodium zinc antimonides NaZn 4 Sb 3 and HT -Na 1– x Zn 4– y Sb 3 were synthesized by using reactive sodium hydride, NaH, as a precursor. The hydride route provides uniform mixing and comprehensive control over the composition, facilitating fast reactions and high-purity samples, whereas traditional synthesis u…
Carbon nanotubes (CNTs) have recently emerged as one of the most promising structures for thermoelectrics (TE). As compared with typical thermoelectric materials, CNTs can be made from almost any carbon-bearing precursor, and so at present thousands of tonnes of them are produced annually at every corner of the world.…
ABSTRACT A series of 16‐layer polypropylene/flame retardant (PP/FR) film/foam composite structures were produced by microlayer coextrusion. A highly branched PP was used in the foam layers to increase strain hardening and cell stability, while the PP used in the film layers was a high shear viscosity grade to confine…
A phenyltriazine compound has been used for the first time as a monomer in the construction of a hydrogel. This physically cross-linked soft material showed blue fluorescence when excited under UV-light. Polymer formation and intermolecular H-bonds arising from triazine moieties operate as aggregation-induced emission…
The paper presents a new method of layered double hydroxide (LDH) synthesis starting from secondary sources, namely acidic residual solutions. The iron content of the acidic solution resulting from the pickling step of the hot-dip galvanizing process make it suitable to be used as an iron precursor in LDH synthesis. H…
Biomaterial scaffolds are under investigation as therapeutic tools to bridge nerve endings following traumatic peripheral nerve injury. The goal is to develop biocompatible nerve guidance conduits (NGCs) with internal guiding structures that promote longitudinally oriented cell migration and regeneration. In the prese…
Abstract We have predicted stable reconstructions of the (100) and (111) surfaces of NaCl using the global optimization algorithm USPEX. Several new reconstructions, together with the previously reported ones, are found. For the cleaved bare (100) surface, pure Na and pure Cl are the only stable surface phases. Our st…
Pressure sensitive adhesives made with blends of thermoplastic polyurethanes (TPUs PSAs) with satisfactory tack, cohesion, and adhesion have been developed. A simple procedure consisting of the physical blending of methyl ethyl ketone (MEK) solutions of two thermoplastic polyurethanes (TPUs) with very different proper…
Surface enhanced Raman spectroscopy (SERS) shows great promise in studying individual atmospheric aerosol. However, the lack of efficient, stable, uniform, large-array, and low-cost SERS substrates constitutes a major roadblock. Herein, a new SERS substrate is proposed for detecting individual atmospheric aerosol part…
