This book describes up-to-date technology applied to high-K materials for More Than Moore applications, i.e. microsystems applied to microelectronics core technologies.After detailing the basic thermodynamic theory applied to high-K dielectrics thin films including extrinsic effects, this book emphasizes the specifici…
Biodegradation rates of cellulosic fabrics in soil have forensic and environmental implications. Th e objective of this fi eld study was to determine the biodegradation rates of 100% rayon, cotton, and lyocell woven fabrics buried in a Captina silt loam soil. Following 14, 28, 42, 77, and 112 days of burial, the fabri…
Magnesium deoxidation equilibrium of molten Fe–Cr–Ni alloy was determined by a chemical equilibrium method at temperature of 1873 to 1973 K. Extreme care was taken of oxygen analysis of the samples. Numerical analysis on Mg deoxidation of molten Fe–Cr–Ni alloy has been carried out by utilizing the model based on Darke…
This chapter summarizes the roles of nanomaterials in biomedical applications, focusing on those highlighted in this volume. A brief history of nanoscience and technology and a general introduction to the field are presented. Then, the chemical and physical properties of nanostructures that make them ideal for use in…
The 222 Rn in soil gas were measured in 0.5m and 1m depth for different locations around Mysore city using Solid State Nuclear Track Detectors. The concentration of radon in soil was observed higher near Chamundi hills and Karighatta village in rainy season. These higher concentrations may be due to higher 226 Ra conc…
We search for marginal Fermi-liquid behavior in the two-band Hubbard model with one narrow band. We consider the limit of low electron densities in the bands and strong intraband and interband Hubbard interactions. We analyze the influence of electron-polaron effects and other mechanisms for mass-enhancement (related…
Stability of Pharmaceutical formulations are oftenly challenged by compatibility between drugs and excipients. The objective of the present study is to identify compatibility between drug:drug and drugs:excipient. Curcumin and Tretinoin were selected as model drug where Ethyl cellulose (EC) and Poly vinyl alcohol (PVA…
The Erosion of Gun Barrels leads to reduced gun performance and availability, and increases the expense of barrel replacement over the life time of a gun system. Wear in gun barrel usually increases the bore diameter near the commencement of rifiling. The wear spreads forwards toward the muzzle as the gun is fired con…
This work deals with the fatigue reliability assessment of a very fast ferry. Based on the analysis of wave and cargo induced loads the ship hull structure is evaluated. The local structure is represented by a longitudinal stiffener with a trapezoidal transverse section and the critical hot-spots and the stress distri…
Voltammetry at Hg drop electrodes is a promising method for detecting sulfide nanoparticles in natural waters. Recent research suggests that such nanoparticles might affect organisms in unforeseen ways. Sulfide nanoparticles diffusing to Hg surfaces are captured selectively even from unfiltered waters that contain lar…
The future of fiber technology for medical applications depends largely on the future needs of our civilization. The use of new fibers for healthcare textiles application has increased rapidly over the past quarter of a century. With the recent advances in tissue engineering, drug delivery, and gene delivery‐ alginate…
Taking a 117 kW 60 000 r/min super high speed permanent magnet generator as an example,the mathematical model for 2D transient electromagnetic field analysis was established,and then magnetic flux lines and air-gap flux density were analyzed by using circuit-field coupled time-stepping finite-element method.The variat…
In the permanent magnet synchronous motors with fractional slot combination,the electromagnetic vibration is generally larger than that of integer slot combination motors,because its force harmonic with the lowest mode number have a major impact on electromagnetic vibration.In the paper,a method,eliminating the harmon…
The effect of sodium hexametaphosphate on the flotation of calcite and its surface properties was investigated by flotation test,IR spectroscopy,adsorptive capacity and ζ potential.The flotation result shows that the inhibition of calcite is remarkable when the sodium hexametaphosphate is used.The mechanism tests indi…
A new fabrication method of ordered metal nano dot array is developed by using coating, nano plastic forming (NPF) and self-assembly due to annealing. In this study, the combination of these processes is studied to produce uniformly-sized and ordered gold nano dot array on a quarts glass substrate experimentally. The…
In order for sub-10 nm thin films of ZrO2 to have a dielectric constant larger than 30 they need to be crystalline. This is done by either depositing the layer at higher temperatures or by a postdeposition annealing step. Both methods induce high leakage currents in ZrO2 based dielectrics. In order to understand the l…
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) imaging analysis was performed on murine macrophage cells treated with various concentrations of iron oxide (Fe3O4) nanoparticles, which are used as MRI contrast agents. First, murine macrophage cells were seeded on a slide glass for 24 hrs and treated with var…
本研究は，相変化蓄熱媒体の一つである酢酸ナトリウム3水和物の熱物性を評価し，その熱輸送プロセスとしての水平密閉矩形容器内自然対流の伝熱特性を実験的に検討したものである．ここでは，酢酸ナトリウム3水和物の熱特性値に対する温度依存性や過冷却現象などを評価し，実使用形態に合わせた熱輸送プロセスに必要不可欠な伝熱データベースを提示した．また，実測した熱物性値に基づいて水平密閉矩形容器内自然対流の熱伝達率を再整理することで，従来から提案されている伝熱相関式と比較・検証しながら液相状態下の自然対流の伝熱特性を解明した．その結果，酢酸ナトリウム3水和物の熱物性値に対する温度依存性を解明するとともに，その過冷却現象には冷却速度の影響を受けた2つの…
本研究は，光学ガラス製造工程で生じる研磨粉や切断片に含まれる希少元素を効率的に分離回収するためのプロセス開発に関する研究の一環として，研磨粉ならびに切断片を塩素気流中，最高到達温度200–1000℃で加熱した時の希少元素（La，Gd，Nb，Ta）ならびに共存元素（Ti，Zr，Zn）の塩化揮発挙動を詳細に追跡した．試料を加熱すると，700℃付近からZnやNb，Ti，Laが急激に揮発し，1000℃までにほぼすべて揮発したものの，Zrは800℃以上で10–90%の揮発率を示した．一方，試料に炭素を添加した場合，LaおよびGd以外の元素の揮発が促進され1000℃までにそれらの全量が揮発した．LaおよびGdは800℃からわずかに揮発し始める…
