In the Urtier valley (southern Aosta Valley, Italy), the Piemonte metaophiolites mainly consist of serpentinized peridotites including pods and boudinaged layers of Fe-metagabbro and trondhjemite transposed in the main eclogitic foliation. The contact between serpentinized peridotites and Fe-metagabbro/trondhjemite is…
The surface of Mg alloy, AZ31 and AZ91, were treated by PEO (plasma electrolytic oxidation) in Na-P system electrolyte, with different applied voltage and time. Thickness, roughness and X-ray crystallographic analysis revealed several results. The more applied time and voltage of PEO treated, the thicker oxidized surf…

Diversas so as variveis que caracterizam a formao de um cordo de solda feito por processos a arco. Mas, nos trabalhos encontrados na literatura acerca das variveis responsveis pela formao do cordo, pouco se discute e justifica-se o uso da representatividade das correntes (mdia e eficaz) na caracterizao da formao de um…
The burst strength is one of the most important characteristics for nonwovens.The strength of three kinds of the nonwoven were detected under four testing radius,including the wood spunlace nonwoven,the SpunbondMeltblown-Spunbond(SMS)nonwoven and the melt nonwoven.The precise results of the SMS and the melt nonwoven c…
Peroxpolytungstic acid (PPTA) is one of the important precursors to synthesize nanostructured tungsten oxides with the chemical routes. In this paper，PPTA sol, being prepared with H2O2, W and C2H5OH, was placed at room temperature for a long time till it was jellified naturally and then was dried at 120 ℃ for 3 hours…
Bipolar electrochemistry has recently been utilized for many new electrochemical applications from electroanalytics to electrodeposition(1). Bipolar electrochemistry is defined as spatially segregated, equal and opposite reduction and oxidation on an electrically-floating conductor. Passage of current in an electroche…
Along with all the developments in the different methods of textile production, technology and skills are also developing, which in turn pushes productivity forward. Functional design and high performance of the fabrics, specially intended for mobiltech, represent the main demand of safety guarantee. The vehicle seats…
Condition of bridges with defects can lead to destruction and at the same time adverse effects on the environment, causing discomfort to society. Therefore, it is necessary to predict the durability of existing bridges, including resistance to increasing number of fatigue cracks, which can lead to the destruction of t…
Pabrik Polyethylene Terephthalate ini direncanakan akan didirikan di kawasan industri Millenium, Tigaraksa, Kabupaten Tangerang, Banten dengan kapasitas 200.000 ton/tahun. Adapun pendiriannya dimulai pada tahun 2019 dan akan mulai beroperasi pada awal tahun 2020. Proses pembuatan polyethylene terephthalate dengan pros…
The use of explosives to attack structures and vehicles has been increasedduring the last few years. The terror attacks lead to death of innocentpeople and to destroy the building (civilian and military). The armoredvehicles and the structures should be protected from explosives attacksusing light weight sandwich stru…
Objective To validate that siAXL‐p5RHH can be a potential therapeutic inhibitor in uterine cancer. Methods A novel serum‐stable, cell‐penetrating, endosomolytic amphipathic peptide delivery system (p5RHH) was used for genetic knock‐down of a receptor tyrosine kinase, AXL. p5RHH peptide was dissolved in 10mM in DNase‐,…
Metal catalyst is one of the most important industrial catalysts, which are widely used in petroleum, coal and fine chemistry fields. Layered double hydroxides (LDHs) are a class of typical anionic clay materials. The tunable composition and structure together with the especial topological transformation properties of…
The over‐production of reactive oxygen species (ROS), known as oxidative stress, has been implicated in many mechanisms of tissue injury. The exact role of ROS remains poorly understood, which has motivated efforts to develop imaging techniques capable of differentiating normal from aberrant biological redox activity.…
ABSTRAK Penelitian bahan bakar reaktor suhu tinggi mendukung Rencana strategis BATAN di bidang energi pada sistem pemasok energi nuklir kogenerasi HTGR. Fasilitas reaktor yang direncanakan dibangun sebagai langkah awal adalah Reaktor Daya Eksperimental (RDE). PTBBN satu tugasnya adalah melaksanakan litbang bahan bakar…
Due to the increasing need to environment protection in real time need to energize new materials are under extensive investigations. Between others, TiO2 nanotubes (TNTs), graphene sheets and WO3 NPs as 1D, 2D and 3D materials are promising alternatives as high efficiency visible light photocatalyst due to their uniqu…
The cost of the production of carbon nanotubes (CNTs) is one of the great challenges. Thermal spray pyrolysis is a simple and economic technique for synthesizing CNT’s at low temperature. Fabrication and characterization of CNTs based thermal pyrolysis process are reported in this work. The precursors, the catalyst, a…
The computation of stress development in casting, welding or quenching of metals has been the scope of several studies since the late 90's and is a well established technique nowadays. The validation of these models was often done by comparing the computed and measured part distortions but validation against the compu…
Safe, economic and reliable operation of nuclear power reactors are the main objectives for improving the current or future reactors. Long term nuclear energy strongly depends on the availability of nuclear fuels, advanced structural materials and passive safety systems. These materialshave to withstand extreme condit…
The mild to severe wear transition of Ti-6Al-4V titanium alloy was investigated. The correlation between microstructure and wear micro-mechanisms was also studied. Hot swaging at 900 C was performed on the as-cast samples and thereafter two different solution treatments were applied on the swaged samples. The first tr…
