Abstract The new title compound is synthesized by solid state reaction from stoichiometric mixtures of Na2MoO4 and Fe2(MoO4)3 (823—853 K, 140 h).
Abstract The isotypic porous compounds K3[FeII4(HPO4)2] [Ge2O(OH)(PO4)4]·2H2O and K3[Cd4(HPO4)2] [Ge2O(OH)(PO4)4]·3H2O are prepared by solvothermal reaction of GeO, Fe or Cd(OAc)2, KCl, H3PO4, H2O, 1,2‐propanediol, and Et3N (autoclave, 190 °C, 5 d; ≈80% yield).
EVALUASI NILAI TERENDAH SISTEM PEMANTAU LAJU DOSIS GAMMA DI RSG-GAS. Telah dilakukan evaluasi umur kerja detektor UJA dengan tujuan untuk mengetahui apakah nilai terendah yang disetting di alat sejak tahun 1985 masih valid. Evaluasi dilakukan dengan cara menghitung aktivitas sumber standar Cs-137 yang ada dalam detekt…
PERHITUNGAN FRAKSI BAKAR ELEMEN BAKAR TERAS KE-82 DI REAKTOR RSG-GAS DENGAN BATAN-FUEL. Selama pengoperasian reaktor dalam satu periode teras, elemen bakar nuklir telah terbakar dengan masing-masing fraksi bakar yang berbeda. Periode Teras 82 dimulai dari 6 Maret s.d. 22 Mei 2013. Energi yang dibangkitkan selama teras…
RSG GAS DENGAN METODE AAN. Penentuan unsur kerak yang melekat pada pipa penukar panas sisi pendingin sekunder reaktor GA.Siwabessy dilakukan untuk mengetahui apakah kerak tersebut terbentuk dari unsur-unsur yang larut dalam air pendingin. Karena itu dilakukan pula analisis terhadap endapan pada kolam air pendingin sek…
In this study, WC-Ni-based cemented carbides having different nickel contents were used as the substrate for cutting tool materials. Hardened steel was turned by a (Ti,W,Si)N-coated WC-Ni-based cemented carbide tool, and the tool wear was experimentally investigated. The following results were obtained: (1) In the (Ti…
The limited solubility of drugs has always been a challenging task for pharmaceutical industries engaged in manufacturing and development of solid dosage forms. To overcome this problem, Liquisolid technique..
Carbon fiber reinforced plastics (CFRP) is a kind of advanced light-weight materials. CFRP is used in various transport equipment in order to increase fuel economy. Laser cutting is one of useful technologies for cutting CFRP. However, heat affected zone (HAZ) is formed at laser irradiation area since the heat conduct…
The first calcium phosphate based biomaterials were introduced in the market almost forty years ago and, due to the compositional resemblance with the mineral constituents of bones and teeth, they became extensively employed in biomedical applications involving bone defects repair. Nowadays, research on calcium phosph…
A new type of floor structure for marine containers utilizes both the excellent properties of wear-resistant and high-strength steels produced by Finnish steel maker Ruukki and the advantages of laser welding. Wear-resistant steel has excellent properties that protect it against wearing and impacts. The high-strength…
The technical results in pig production are constantly increasing. The improved quality of the feed is a big part of this success. According to the Dutch feed company, Agrifirm, results can be further improved by using the extrusion technique. With the current high feed prices, the interest for this type of feed is in…
This article presents experimental analyses of total indicated runout, which is the synergetic effect of mechanical and electrical runouts, and residual stress of three different material coatings on a large rotary component, which are prepared with laser cladding. These coating materials include cobalt-, and iron-bas…
Acquisition of the as-received industrial material absorptance of light is important for guiding the laser machining processing. However, most of the published absorptance data presently used take only polished pure metals into account rather than the engineering grade alloys which are actually being processed with di…
In this research, the laser weldability for tailor-welded blanks (TWBs) made of dissimilar hot-stamping steels was examined. Usibor and Ductibor from ArcelorMittal were combined, since they are steels that possess a high strength and high energy absorption, respectively. After laser butt welding, the specimens were he…
Various welding processes are now available for the end plug closure of a nuclear fuel element such as gas tungsten arc welding (GTAW), magnetic resistance welding, and Nd:YAG laser beam welding (LBW). Even though the resistance and GTAW processes are widely used for manufacturing commercial fuel elements, they cannot…
In fast neutron reactors, some parts can be submitted to displacements between each other (as movable parts for example). On these parts, the contact areas usually need a hardfacing coating. The standard hardfacing alloy is a cobalt-base alloy (as, for example Stellite®6). Unfortunately, in the primary coolant circuit…
In recent years, laser micromachining of semiconductor materials such as silicon and sapphire has attracted more and more attention. High power Diode Pumped Solid State (DPSS) lasers have been gained wider application in microelectronics, flat panel display, and solar cell manufacturing industries because it can obtai…
The use of pipelines tubes with an inner layer of corrosive resistant alloys (CRA) (Stainless steel or nickels base alloys) is increasing for the oil extraction industry, mainly for environmental protection considerations. Final quality constraints need the use of conventional slow processes to reach the required buil…
