Advanced high strength steels (AHSS) are used for car body applications in the automotive industry to improve passenger safety, improve fuel efficiency and to lower harmful carbon emissions. Galvannealed AHSS are used to provide corrosion protection. AHSS are alloyed with several elements such as Mn, Si, Al, P, Mo, etc. to achieve better mechanical properties. However, the knowledge of the effe...

This paper describes an approach to measuring extinct fission products that would allow for the characterization of a nuclear test at any time. The isotopic composition of molybdenum in five samples of glassy debris from the 1945 Trinity nuclear test has been measured. Nonnatural molybdenum isotopic compositions were observed, reflecting an input from the decay of the short-lived fission produc...

High-pressure melting anchors the phase diagram of a material, revealing the effect of pressure on the breakdown of the ordering of atoms in the solid. An important case is molybdenum, which has long been speculated to undergo an exceptionally steep increase in melting temperature when compressed. On the other hand, previous experiments showed nearly constant melting temperature as a function o...

Rapid type 2 molybdenum(V) e.p.r. signals from reduced functional xanthine oxidase have been further investigated. These signals, which show strong coupling of two protons to molybdenum, have been obtained under a variety of new conditions: specifically either at pH 8.2 in the presence of borate ions, or at pH 10.1--10.7 with or without various other additions. Parameters of the signals were ob...

Novel periplasmic and membrane-bound nitrate reductases lacking molybdenum and molybdenum cofactor were isolated from the vanadate-reducing bacterium Pseudomonas isachenkovii, and their properties were studied. Both enzymes have some unusual features, i. e., the individual subunits (130-kD subunit of the membrane-bound enzyme and monomeric 55-kD subunit of the periplasmic enzyme) possess their ...

Alcator C-Mod is a high-field tokamak with which experiments were initiated in April 1993. The divertor and the first-wall have plasma-facing surfaces of molybdenum. The divertor has a configuration which is closed in comparison to other, currently operating tokamaks. The combination of divertor geometry and high field (density) make Alcator C-Mod an ideal experiment to investigate dissipative ...

Selective Laser Melting (SLM) offers great potential for future manufacturing technology. In order to extend its applicability for the processing of high melting materials like molybdenum fundamental process understanding is required. This can be obtained by multi-physical simulations that allow a look into the process. In this contribution a thermofluiddynamical simulation model for laser beam...

Atomically thin two-dimensional materials have emerged as promising candidates for flexible and transparent electronic applications. Here we show non-volatile memory devices, based on field-effect transistors with large hysteresis, consisting entirely of stacked two-dimensional materials. Graphene and molybdenum disulphide were employed as both channel and charge-trapping layers, whereas hexago...

This article discusses the spectral dependences of absorption coefficient thin arsenic sulphide films obtained by spin-coating, identified using a single-beam spectrophotometer in wavelength range 400–1000 nm. The effect doping molybdenum on optical band gap is studied. While for pure glass decreases with higher sulphur concentration, opposite trend observed doped molybdenum. Molybdenum also le...

the possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. the results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. on the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...
