Abstract Front Cover: Highly aligned 3D silk scaffolds using directional freezing in a custom designed chamber was demonstrated. The method is versatile and holds potential to produce complex, multicomponent aligned structures for various tissue engineering and biomedical applications, needing immediate cell alignment…
The tensile mechanical properties of graphene nanoribbons (GNRs) with five types of edges are investigated in the range of 1K to 800K by molecular dynamics simulations. The results show that the Young's modulus of GNRs varies with different edges, and the Zigzag GNRs have larger Young's modulus and tensile strength th…
Rice husk ashes are a potential source of pollution, thus there is continued interest in its recycling. An environmentally friendly solution is its conversion into products such as aluminosilicates that are designed for use as fertilizer. Aluminosilicates that present a high cationic exchange capacity becomes an excel…
This work is based on the research supported by the South African Research Chairs Initiative of the Department of Science and Technology, the National Research Foundation of South Africa, University of the Free State Cluster Fund and Rhodes University Physics departments. Also the services of the research equipment of…
Nickel molybdate (α-NiMoO4) nanoparticles were prepared by a solution combustion synthesis (SCS) technique and, for the first time, were studied as a potential electrode material for supercapacitors. High specific capacitance (1517 F g-1) and energy density (52.7 W h Kg -1) were delivered by nano-α-NiMoO4 at a current…
The main laws governing the titanium surface layer alloying with chromium atoms by compression plasma flows (CPF) and the influence of low-energy high-current electron beams (HCEB) are investigated. Titanium samples with a previously deposited chromium coating were subjected to the CPF impact and HCEB. In both cases,…
Self-diffusion coefficients of titanium and cobalt in a silicon melt with 10 at.% metal content were measured in a temperature range between 180 K above and below the liquidus temperature, respectively, with quasielastic neutron scattering. The chemical reactive melts were processed container-less by electromagnetic l…
皮膚は最外層に位置する臓器であり，温湿度，日照量等の環境や日焼け等の流行といった体外から身体に影響を及ぼす外的要因や，かゆみ，痛み等の身体内部の個人差に起因する内的要因からの影響を受け，その状態は個人間でさまざまに異なっていると考えられる。したがって，それら外，内的要因を知り適切なスキンケアをすることは，健やかで美しい肌を維持するために重要であると考えられる。そこでわれわれは，外的，内的要因による皮膚状態の違いや変化が存在するかを検討するために，沖縄県から北海道に及ぶ日本全地域の，のべ5893536件の女性の皮膚状態の調査を20年間にわたり行ってきた。その結果，見た目のシミ，肌の色，シワの状態が2000年付近を境に傾向が変化し，こ…
Closed‐cell cross‐linked PVC foams display high specific strength and stiffness and are frequently used as core of light‐weight sandwich structures, such as inner aircrafts panels. The compressive behaviour of a commercially available foam was investigated under both static and dynamic conditions. An ad‐hoc apparatus…
2,2′-Azobis (2-methylpropionamidine) dihydrochloride-montmorillonite (AIBA-MMT) hybrid was prepared by cationic exchange between the Na + ion in the MMT galleries and the quaternary ammonium of the azo-initiator. Then the methacrylic acid-ethanolamine modified maleic anhydride copolymer/montmorillonite [P(MAA-EMA)/MMT…

Helicobacter pylori infection induces a chronic gastric inflammatory infiltrate. This study was undertaken to evaluate the type of the innate immune responses elicited by the secreted peptidyl-prolyl cis-trans isomerase of H. pylon (100175). The cytokine production induced by HP0175 in neutrophils, and monocytes was e…
A series of noval organic-inorganic nanocomposite materials of hydroxyapatite/poly(vinyl pyrrolidone) were synthesized by in situ copolymerization of modified inorganic nanoscale hydroxyapatite and poly(vinyl pyrrolidone).The hydroxyapatite/poly(vinyl pyrrolidone) nanocomposites were characterized by scanning electron…
This paper reports on research of possibilities for composite materials bio matrices synthesis from MDF boards withdrawn from usage. Bio matrices were cast produced using re-defibrated wood fibres as raw material for cellulose polymorphs isolation and acetylation. As acetylation reaction time and temperature directly…

Manganese-crystallization of formic acid from the decomposition of N,N-dimethylformamide solvent was synthesized and characterized by single-crystal X-ray diffraction. This compound crystallized in a hexagonal space group of R-3c with a = b = 8.3319(5) Å, c = 22.851(2) Å, a = b = 90.00º, l = 120.00º, V = 1373.81(17) Å…
Some traditional techniques, such as hydrothermal synthesis, microemulsion techniques and solvothermal synthesis, are applied to prepare metal-organic frameworks and non-metal-organic frameworks. In this article, we present a morphology-controlled synthesis of nonmetal-organic frameworks by using a surfactant-assisted…
