In recent years, there have been a number of studies done on gallium nitride (GaN) because of \nits promising electronic and thermal properties. Its characteristic features are a wide bandgap, \nhigh electron mobility, and high thermal stability [1]. GaN has been used in electronic devices \nsuch as light emitting dio…
Variants of fibrous sorbents for separating water from oil and oil products are considered. The design-layout scheme of a floor-mat-sorbent multiple sorption is offered.
The article analyzes the calculation problems of press multilayer compounds with heterogeneous structure of the intermediate element. The specific features of calculation of the selected group of multi-layer compounds are determined. The promising follow up study for further improvement of the calculation of the stres…

Theoretical and experimental studies of nanostructured materials
The impact of high-speed (500-1500 m/s), laser driven micro-fliers with thin energetic targets (10-100 &# 956;m) is being examined to characterize impact-induced heating and combustion of these materials. Aluminum fliers are propelled by a laser into a thin metallic target plate having a layer of energetic material de…
采用离心浇铸,经剖切、热锻、热轧工艺制成16MnV/9Cr18MoV/16MnV 3层金属复合板。热轧后成品板金相组织观察发现,复合板一侧16MnV/9Cr18MoV界面清晰,另一侧9Cr18MoV/16MnV界面存在一模糊过渡带。扫描电镜成分分析显示,模糊界面过渡带上,Cr元素在16MnV区域有大量的混合,说明浇铸第3层16MnV时,较高熔点的16MnV熔化了较低熔点的9Cr18MoV,造成2种材料发生了强烈的混合,形成不对称的结构。这种不对称结构对力学性能及刀具的使用都会产生影响。
Modeling of manufacturing processes has been deeply studied and computational methods and softwares are now able to deal with difficult scientific problems coming from complex industrial issues. However research teams are still very active in this domain and my research works aim at improving CPU time resulting from i…
Nuclear waste disposal research is promoted on a European Union level by different programmes and activities. The legal basis is the EURATOM treaty, signed 25 March 1957 in Rom as one of the two founding trea¬ties of what has become the European Union. Key actors for implementation of such research programmes and asso…
There is a growing recognition of the need for consensus among all stakeholders in the construction development process; recent years have witnessed a growing interest in the integration of the built environment and building cost. There is, therefore, a clear need to better integrate building cost into the sustainable…
The RI was calculated from the ratio of aromatic (TYR, PHE) to non-protein AA (GABA, BALA; see text).
Telah dilakukan suatu analisistransien terhadap teras silisida RSG-GAS akibat kehilangan aliran pendingin (LOFA). LOFA dapat terjadijika catu daya listrik pompa pendingin primer mati, maka laju alir pendingin berkurang. Pada saat laju alirpendingin berkurang 15% yang mengakibatkan sistem proteksi reaktor bekerja. Anal…
Bejana tekan merupakan satu bagian dari reactor coolant pressure boundary, dan integritasnya sangat penting dijaga untuk keselamatan operasi dari reaktor. Inter Granular Stress CorrosionCracking (IGSCC) merupakan mekanisme degradasi penting yang perlu dipertimbangkan untukkeselamatan komponen nuklir yang terbuat dari…

Untuk tahun 2011, program utama terfokus pada kegiatanpengembangan fasilitas laboratorium termohidrolika reaktor tipe…
Inconel 690 digunakan sebagai material tube pembangkit uap pada reaktor PWR (PressurizedWater Reactor / Reaktor air bertekanan) karena ketahanan korosi yang bagus dalam lingkungan/media suhu dan tekanan tinggi. Pada penelitian ini telah dilakukan pengujian korosi dengan melihatpengaruh suhu dan variasi konsentrasi NaC…
Penelitian sebelumnya telah dilakukan perhitungan faktordaya (ppf) dan reaktivitas batang kendali teras RSG-GAS berbahan bakar U3Si2-Al 4,8gU/cc dengankawat kadmium. Nilai Reaktivitas batang kendali dan ppf teras tersebut telah memenuhi margin keselamatan.Dalam penelitian ini dilakukan analisis terhadap parameter kese…
The possibility to covalently bind the amino compounds and glycine with the detonation nanodiamonds surface was shown. The functionalized nanodiamonds were studied by IR-, Raman-spectroscopy and XPS methods. The luminescence was discovered in case of such nanodiamonds which depended on the chemical structure of the gr…
