Significance and Use 4.1 Ionizing radiation produces physical or chemical changes in many materials that can be measured and related to absorbed dose. Materials with radiation-induced changes that have been thoroughly studied can be used as dosimeters in
プロ2・イノベーションを「プロダクト・イノベーションと拡張概念のプロセス・イノベーションが共進するイノベーション」と再定義し，①クオンタム・リープ型，②ブレイド・アップ型を提示する。プロ2・イノベーションはビジネスモデルを顧客のプロセスに着目しつつイノベートする際の，有力なオプションである。単なるひらめきに頼らず，論理的にアイデアを導出して試行錯誤のピッチを速めることができるからである。
采用甘氨酸-硝酸盐法(GNP)制备Gd 0.8 Sr 0.2 CoO 3- δ (GSC)纳米粉体。通过元素化学计量、热力学计算及XRD、SEM、交流阻抗谱等测试手段, 研究了甘氨酸与金属离子摩尔比( G / M =1.5、2.0、2.5、3.0、3.5)以及煅烧温度等制备参数对GSC粉料合成反应及电极性能的影响。实验测得凝胶自燃烧时火焰温度在850~1150℃之间, 其中 G / M =2.5时火焰温度最高, 燃烧最完全, 与理想化学计量( φ =1)的计算结果相一致, 由此制得的粉料呈蓬松泡沫状, 粒径细小。交流阻抗谱测试结果表明: 1100℃煅烧制得的GSC-2.5阴极与Sm 0.2 Ce 0.8 O 1.9 (SDC)电解…
Objective To investigate the expression of ligands of DNAM-1 and NKG2D in the colonic cancer.Methods The colonic cancer tissue and adjacent normal colonic tissues were collected from 42 colonic cancer patients who were admitted to the Tangdu Hospital of Fourth Military Medical University from June 2010 to January 2011…
Τα σύνθετα υλικά C/C-SiC χρησιμοποιούνται ήδη από το 1970 σαν μέσα θερμικής προστασίας για τα διαστημικά οχήματα, αλλά έχουν εφαρμογή και οπουδήποτε αλλού απαιτούνται υψηλές μηχανικές αντοχές και χαμηλή θερμική αγωγιμότητα. Η μικρή τους αντίσταση απέναντι στην οξείδωση σε υψηλές θερμοκρασίες δημιούργησε την ανάγκη για…
The versatile and relatively inexpensive (low energy cost) synthesis of new organic molecules is important for pharmaceutical production, polymerization, and other industrially applicable facets of chemistry. Electrochemical reduction of unsaturated organic compounds at room temperature to new organic products offers…
The mechanical integrity of wirebonds is sensitive to structures under the bond pads of ultra low-k dielectric devices. The authors calculated homogenized material properties of two basic wiring structures with three different wiring pitches in the device. Stress in the ULK layer under the bond pad was analyzed using…
MOD method was used to prepare (1-x)Na0.5Bi0.5TiO3-xK0.5Bi0.5TiO3 (NBT-KBT100x) relaxor piezoelectric thin films. The surface morphology, the initial domain structures, domain switching, retention and imprint of NBT-KBT100x thin films were observed by PFM under different external fields. The results show that the NBT-…
Uniform scanning proton beams work by scanning a pencil-beam of radiation throughout the entire area of the treatment field. Specifically for Princeton Procure Management, LLC in Somerset, NJ (ProCure NJ), the beam is scanned at 30 hertz (Hz) in the vertical direction, and 3 Hz in the horizontal direction. The time it…
Today, 70% of all bacterial strains are resistant to at least one antibiotic. Bacteria have become resistant to antibiotics through several methods, including mutations in their genome. Antibiotic resistance continuities to grow based on several factors. These include over-prescription of antibiotics by physicians, no…
Freshwater ecosystems will likely become sinks for future silver loadings as a result of \nincreased nanosilver (n-Ag) use in industrial and commercial applications. A series of bioassays \nwas performed to assess how n-Ag toxicity may be influenced by abiotic factors associated with \nnatural freshwater ecosystems. A…
The tailored surface modification of electrode materials is crucial to realize the wanted electronic and electrochemical properties. In this regard, a dexterous carbon encapsulation technique can be one of the most essential preparation methods for the electrode materials for lithium rechargeable batteries. For this p…
The charge retention behaviour of MNOS structures with embedded Si or Ge nanocrystals are studied by computer simulation.It is obtained that the oxide thickness and the location of nanocrystlas affect the retention behaviour very strongly.The retention time changes from a few ms to several years.
The correlation between resistivity and volume changes in manganite of system LaMnO3 under the influence of temperature T, hydrostatic pressure P and magnetic field H was considered. It was shown that each of the factors T, P. H gives its contribution in the amount of the resistivity, which is determined by the specif…
The nature of adsorbed species on catalytic surface over an industrial precipitated iron-based high temperature catalyst during FTS was investigated by in-situ DRIFTS and chemical trapping. The formulation of the mechanism of oxygenates formation and key intermediates were also discussed. Numerous oxygenated precursor…
The experimental results of the effect of the gas phase composition on nitrogen-doped nanostructured diamond coatings synthesized in the glow discharge plasma on their structure and resistance have been presented.
