In the past decades many techniques have been developed to reduce isobaric contaminations in ISOL (Isotope Separation On‐Line) beams. Another promising method to achieve improved selectivity is employing surface effects in the transfer line between target container and ion source. Thus adsorption materials with suitab…
A set of elastic constants was calculated and a parametrization of the potential was derived for simple cubic tungsten trioxide based on an analytical bond-order scheme. It was shown that the obtained parametrization provided a good description of interatomic forces and such properties as the lattice constant, the bul…
Atomic force microscopy (PFM), invented in 1986, has found widespread use in science. The technique enables imaging of material at the molecular level for the first time. Unlike most other microscopy techniques, the imaging can be carried out in situ without fear of destroying the integrity of the inter-phase and the…
A reparacao dos tecidos que compoem a parede abdominal e uma necessidade cirurgica constante. Especificamente para utilizacao em animais domesticos, o maior desafio e o desenvolvimento de biomateriais que suportem forcas exercidas pelas visceras, em virtude de sua posicao quadrupedal e pela movimentacao das estruturas…

薄电影被建议的为半导体的弯曲半径的精确决心的一个方法。如果在 XRC 的半最大值(FWHM ) 的完整的宽度的依赖作为事件 X 光横梁的宽度的功能被测量，摇 heteroepitaxially 成年的层的曲线(XRC ) 的 X 光的导致弯曲的拓宽能是坚定的。二的弯曲半径轧了在蓝宝石晶片上种的电影，这被发现当他们在类似的 MOCVD 条件下面是成年的，但是有层厚度的不同价值时，是不同的。同时， XRC 并且这样的导致脱臼的拓宽取向附生的电影的脱臼密度能很好在弯曲修正以后被计算。
The selected results of investigations of the cooling system for the combustion engine working with higher temperature of the cooling liquid were presented. The temperature of this liquid were increased to the temperature of boiling water, as a basic compound of the cooling liquid. This system was designed for the fou…
The electronic properties of multiferroic BaCoF4 with ferroelectric antiferromagnetic phase and paraelectric phase are calculated using density functional theory with spin-polarized generalized-gradient approximation and plane wave pseudopotentials. It is found that anti-ferromagneticism probably favors to the ferroel…
Early failure during dwell-fatigue of titanium alloys is a research of interest as it directly drives the in-service life of critical parts in turbines.A study was undertaken to examine the evolution of life and strain in six specimens made of near-alpha titanium alloy (IMI 834) during dwell-fatigue loading conditions…
Abstract: This paper examines the dynamics of shock induced collapse of an air bubble in water and discusses the resulting collapse geometry, pressure and temperature. FronTier, a front tracking algorithm, is used to resolve the motion of the air/water interface. A series of plane shock intensities and bubble sizes ar…
Efficacy of the oxygenated regenerated cellulose Surgicel Nu-Knit as a hemostatic agent by coronary shunting operation was evaluated. 84 patients were included in the study. Surgicel was locally used in 32 of patients after sternotomy and during wound closure. Intraoperative blood loss in the group of interest was hig…
Gate‐all‐around (GAA) SiGe nanowire transistor structures have been studied using high angle annular dark field (HAADF) STEM tomography. Sample preparation has been optimized by isolating single devices in needle‐shaped specimens, using annular milling in the focused ion beam (FIB). Using this technique, images can be…
Effects of different annealing temperature, holding time and degree of deformation on recrystallization rate of Aluminium alloy (6063) were studied. Fifteen suitably dimensioned samples were prepared from Aluminium alloy (6063). Seven of these were subjected to 70% cold plastic deformation, seven to 90% and one left u…
In the biomaterial field, the modification of surfaces are used to create polymers with high performances, preserving their bulk properties and creating specific interactions between the designed surfaces and the cells or tissues. The polymers were irradiated with a 900 keV Helium beam to modify their surface properti…
The nanosized filler influence on the physicochemical and electrical properties of the composite ceramic-polymer (CP) material to be applied in outdoor line HV insulators has been investigated. Also the results of the electrical and mechanical examinations of the CP insulators moulded with the use of the dies made of…
We demonstrate and monitor an efficient edge reconstruction process, at the atomic scale, for graphite nanoribbons by Joule heating inside an integrated transmission electron microscope equipped with a scanning tunneling stage STM (TEM-STM system). During Joule annealing, sharp edges and step-edge arrays are formed, m…
Due to the increasing demand for products which use Non-Volatile Memory (NVM) and the near realization of the scaling limits of Flash [1, 2], a large research effort is underway. This effort is to develop new forms of NVM capable of replacing Flash [3]. At the forefront of this research is Phase-Change Random Access M…
Copper tin sulfide thin films were electrodeposited on the indium tin oxide substrates in a bath containing CuSO4, SnCl2 and Na2S2O3 solutions. Various pH values ranging from 1.1 to 1.5 were attempted in order to determine the optimum condition for electrodeposition process. The structure and morphology of the films w…
Abstract � This paper analyzes accuracy of algorithms commonly adopted in instrument devoted to the detection and the characterization of voltage dips (also called sags). This analysis is particularly interesting because the results of dip measurements are utilized for calculation of severity levels and the site index…
The main objective of the paper is to verify the discrete random walk (DRW) and thecontinuous random walk (CRW) Lagrangian Particle Tracking models as a tool to calculatedeposition in nuclear fuel ...
