Molecular wheels: Decacoordinated molecular wheels, Ta©B10− (see picture) and Nb©B10−, showing the highest coordination number for the central atom in a planar environment at present, were produced in a laser-vaporization supersonic molecular beam and characterized by photoelectron spectroscopy and ab initio calculati…
Partial discharge (PD) is usually aroused before the failure of gas insulated switchgear (GIS) caused by defects, which results in the decomposition of the SF6used as insulating gas. Analyzing SF6decomposition products can aid in PD detection. Before recognizing PD types by analyzing SF6 decomposition products, the de…
Magnesium based alloys possess a natural ability to biodegrade due to corrosion when placed within aqueous substances, which is promising for cardiovascular and orthopedic medical device applications. These materials can serve as a temporary scaffold when placed in vivo, which is desirable for treatments when temporar…
Sulfidation of metallic nanoparticles such as silver nanoparticles (AgNPs) released to the environment may be an important detoxification mechanism. Two types of AgNPs-an engineered polydisperse and aggregated AgNP powder, and a laboratory-synthesized, relatively monodisperse AgNP aqueous dispersion-were studied. The…
The design of nanoparticle (NP) size, shape and surface chemistry has a significant impact on their performance. While the influences of the particle size and surface chemistry on drug delivery have been studied extensively, little is known about the effect of particle shapes on nanomedicine. In this perspective artic…
Phase-change random access memory (PRAM) is considered as one of the most promising candidates for future memories because of its good scalability and cost-effectiveness [1]. Besides implementations with standard interfaces like NOR flash or LPDDR2-NVM, application-oriented approaches using PRAM as main-memory or stor…
Based on first-principles calculations, we predict that 5d transition metals on graphene present a unique class of hybrid systems exhibiting topological transport effects that can be manipulated effectively by external electric fields. The origin of this phenomenon lies in the exceptional magnetic properties and the l…
We report on the enhanced thermoelectric properties of selenium (Se) doped bismuth telluride (Bi(2)Te(3-x)Se(x)) nanoplatelet (NP) composites synthesized by the polyol method. Variation of the Se composition within NPs is demonstrated by X-ray diffraction and Raman spectroscopy. While the calculated lattice parameters…
BACKGROUND: Development of an environmentally benign process for the synthesis of silver nanomaterials is an important aspect of current nanotechnology research. Among the 600 species of the genus Dioscorea, Dioscorea bulbifera has profound therapeutic applications due to its unique phytochemistry. In this paper, we r…
The polyaniline (PANI)/TiO 2 nanocomposites have been successfully synthesized via a hydrothermal method and followed by a low-temperature calcination treatment process. We find that such a PANI/TiO 2 nanocomposite exhibits higher photocatalytic activity and stability than bare TiO 2 and TiO 2- x N x toward the liquid…
Advanced materials with surfaces that have controllable oil wettability when submerged in aqueous media have great potential for various underwater applications. Here we have developed smart surfaces on commonly used materials, including non-woven textiles and polyurethane sponges, which are able to switch between sup…
Most materials expand upon heating. However, although rare, some materials contract upon heating. Such negative thermal expansion (NTE) materials have enormous industrial merit because they can control the thermal expansion of materials. Recent progress in materials research enables us to obtain materials exhibiting n…
BACKGROUND: Zinc oxide nanoparticles (ZnO NPs) have received much attention for their implications in cancer therapy. It has been reported that ZnO NPs induce selective killing of cancer cells. However, the underlying molecular mechanisms behind the anticancer response of ZnO NPs remain unclear. METHODS AND RESULTS: W…
Ferroelectrics are essential components in a wide range of applications, including ultrasonic transducers, sensors, and actuators. In the single crystal form, relaxor-PbTiO3 (PT) piezoelectric materials have been extensively studied due to their ultrahigh piezoelectric and electromechanical properties. In this article…
Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. This review introduces the field of nanotechnology with a focus on recent gold nanoparticle research which has led to early-phase clinical trial…
We report the thermal- and pressure-induced spin-crossover (SCO) in the Co(II) imide complex [CoII(dpzca)2] using magnetic susceptibility measurements and high-pressure Raman spectroscopy. This complex displays thermally-induced reversible, complete, abrupt and hysteretic SCO, with T1/2↓ = 168 K upon cooling and T1/2↑…
Au cours de la précipitation oxalique, trois mécanismes majeurs ont lieu : la nucléation, la croissance cristalline et l’agglomération. Après l’acquisition des lois cinétiques de nucléation et croissance des oxalates de néodyme III et d’uranium IV par Andrieu (1999), l’objectif de cette étude est d’acquérir la loi d’a…
生活者に対する投資信託販売には、ファイナンシャル・プランニング活用が望ましい。そして、その多様な技法はライフプランとマーケット、そしてポートフォリオという3つの焦点によって整理可能であり、①ヒアリング、②顧客の実情・ライフプランの認識、そして投資教育、③商品に影響するマーケット、④具体的な個別商品を組み合わせた運用提案、そして、⑤アフターフォローという5つのステップで展開されることが妥当である。
ニットは自重の影響を受けて着用丈や衿ぐりが変形し、シルエットが予想と異なることがあり、パターンメーキングの際に、着用時の伸長特性を考慮する必要がある。本研究では、ニットの自重による伸びを定量的に捉え、自重による伸びを推定する手法を提案することを目的とした。矩形布による自重伸長において、ウェール方向の試長の2 乗と伸びの間に比例関係が成立し、見掛けのヤング率と平面重から推定伸長を求める式を得た。ワンピースをボディーに着装した場合のウェール方向の部位別伸長は、上部から下部に行くに従って減少していき、自重が大きくかかる上部ほど伸び変形は大きい。バスト部では、その突出が布をおし拡げる力として作用するため大きな伸び率になることがわかった。着…
Oxo-halogénures de cobalt : Compréhension de l’influence des substitutions cationiques et anioniques Ce travail a consisté en la synthèse, l’étude structurale et les caractérisations physico-chimiques de systèmes dérivés des polytypes 6H et 10H des perovskites hexagonales de formule BaMX0.2-xO3-δ (M=Co, Fe, Mn; X=F, C…
