In this article, we report recent development of miniature high-pressure apparatus for bulk measurements at low temperature and in magnetic field. The new compact multi-anvil type “Palm cubic anvil cell” extends the temperature range down to ∼0.45 K by using a 3He refrigerator. We also present a technique for measurin…
超音波照射下の空気のマイクロバブルの高速挙動による洗浄効果に関する検討を行った．高速度カメラを用いて，20 kHz, 600 Wの出力の超音波照射下での空気のマイクロバブルの試料表面での挙動を撮影した．マイクロバブルは単一の形状を維持したまま，試料表面を高速で移動しながら凝集することが明らかとなった．油性インク，カーボン汚れに対する洗浄実験を行い，超音波照射下のマイクロバブルの物理的挙動が洗浄効果につながることを明らかにした．超音波洗浄で見られたキャビテーションのスポットダメージは，マイクロバブルの共存時にはほとんど見られなかった．これはマイクロバブルが洗浄面を覆うため，ダメージの原因となるような洗浄面付近でのキャビテーションが発…
高分子溶液の粘度は，高分子の分子量や濃度，および鎖の剛直性に強く依存することが知られている．本報では，5種類の剛直性の異なる高分子溶液に対する広い分子量・濃度範囲にわたるゼロずり粘度を，みみず鎖円筒およびファジー円筒モデルに基づいて定式化された粘度式と比較した．この粘度式には，ファジー円筒の縦方向の並進拡散を支配する臨界空孔サイズを特徴づけるパラメータと分子間流体力学的相互作用の強さを表すパラメータが分子論的に決められない調節パラメータとして含まれている．前者については高分子溶液の種類や分子量によらない一定値を，また後者には溶液の種類と高分子の分子量ごとに適当な値を代入すると，粘度式は調べた5種類の高分子溶液系とも広い分子量・濃度…
UCAs is necessary and needed. Researchers have been developed the equation for modeling free gas microbubble oscillation based on the relationship between the physical parameters of the encapsulated microbubble and the excitation pressure as reported in (9-10). For example, the subharmonic simulations resulting from t…
In our previous work we showed that taxanes (paclitaxel (Ptx) and docetaxel(Dtx)) can be spontaneously loaded into monosialoganglioside (GM1) nanomicelles, increasing their water solubility about 6,000 times, to render stable water soluble formulations that could be used as a novel strategy to deliver drugs in cancer.…
Cathode-supported tubular solid oxide fuel cells (CS-T-SOFCs) have been regarded as promising energy conversion devices; however, their commercialization is blocked by high manufacturing cost and poor electrochemical performance. In our group, dip-coating and co-sintering techniques were used in order to reduce the co…
In the 21st century, as it is important to produce products with high quality, hybrid properties, multi functions, low cost, Eco-friendly and so on, the most of manufacturers need several daring plans, unique ideas, new technologies. Therefore a software for creating new materials with hybrid properties desired from m…
The effect of cavitation treatment of micro and nano fillers in relation to ultra-high performance concrete (UHPC) was investigated in this paper. Specially designed and patented apparatus was applied to create turbulent flow and employ hydrodynamic cavitation process as a tool for silica fume micro and nano particle…
大環状配位子であるカリックスアレーン誘導体を基体とする溶媒抽出試薬を開発した．得られたデータを元に分離分析試薬への応用として，カリックスアレーン誘導体を含有する4種類のイオン交換樹脂，ならびに銀イオン選択性電極を開発した．カルボン酸誘導体を含むイオン交換樹脂については金属の吸着挙動をバッチ法とカラム法により検討した．カリックス［4］アレーン誘導体を含有する樹脂は鉛に対して高い選択性を示し，メチレン架橋したカリックス［4］アレーン樹脂は高い鉛充填容量を示した．また，鉛と亜鉛のクロマト分離で両者が効率的に分離された．カリックス［4］アレーンケトン誘導体や2-ピリジル誘導体を素子として作成した電極は銀イオンに対して高い選択性を示した．溶…
Abstract — Porcelain string insulators are extensively utilized in high voltage transmission lines. However, the electric field and potential distribution along an insulator string owing to the existence of metal conjunctions and resulting stray capacitances is not uniform and the units near to energized end fitting a…
In order to understand the behavior of scale deformation on hot-rolling, the characteristic of not only scale itself but also the interface between scale and material is important.For this reason, the following experimental methods were developed for measuring the quantitative strength of the interface. At first, afte…
Effect of dicarboxylic acids : malonic acid (MA), succinic acid (SUA), and glutaric acid (GA), on the preferential cocrystal formation with carbamazepine (CBZ) was investigated. Stoichiometries of CBZ / MA, CBZ / SUA and CBZ / GA cocrystals formed were 2 / 1, 2 / 1 and 1 / 1. When CBZ / SUA ground mixture (GM) was cog…
The aim of the present study was to investigate the effects of intraperitoneal administration of GNPs on the histological alterations of the lung tissue of rats in an attempt to cover and understand the toxicity and the potential role of GNPs as a therapeutic and diagnostic tool.
The purpose of this paper is to consider a two-dimensional version of the Aifantis equation of statics of the theory of consolidation with double porosity and effectively solve the basic BVPs for the half-plane. We extend the potential method and the theory of integral equations to BVPs of the theory of consolidation…
In environmental analysis, the commercial reagent and reference material products of analyte compounds are indispensable for chromatography such as GC/MS and LC/MS. However, most of their purities are not certificated traceability to the International System of Units (SI). Hence the possibility that their obscure puri…
Current ability and expecting future development of first-principles predictive modeling for studying mechanical properties of materials is comprehensively discussed by means of introducing recent publications and reports. Particulary, I pick up topics for the elastic properties (e.g., elastic constants, elastic strai…
To introduce self-organization ability of transmembrane proteins into Langmuir (L) and Langmuir-Blodgett (LB) techniques, we focused on "amphiphilic peptide" (AP) which is composed of two distinct hydrophilic and hydrophobic domains. Three types of APs of different average hydropathies were used to prepare the AP/lipi…
In this paper, we investigated the feasibility and effect of a novel combination therapy of magnetic nanoparticles (MNPs) hyperthermia with anticancer drugs for solid malignancies using doxorubicin-loaded alginate-templated magnetic microcapsules (DAMMs) in an animal liver cancer model. Firstly, DAMMs containing 18 nm…
Adhesion of microorganisms and biofilm formation on the surfaces of some single alloys and plated steels were evaluated in order to estimate the inhibition capability against biofilm formation on these materials. SS400, 304 steel and 430 steel were used for test materials. Ag, Co, Cr, Cu, Ni, Sn and Zn plated steels w…
