The interaction between plasma particles and tungsten as plasma facing material is one of the critical issues in successfully using tungsten in Tokamak reactors environment. The deuterium bombardment of monocrystalline tungsten was modeled by molecular dynamics simulation using LAMMPS code and Tersoff type interatomic potential. The deuterium trapping rate, implantation depth, and the stopping ...

The reliability of electroluminescence from metal–oxide–silicon ~MOS! tunneling diodes was improved by the incorporation of deuterium. The deuterium was incorporated by the deuterium prebake and the postoxide deuterium annealing. At constant current stress of 100 mA, a deuterium-treated n-channel MOS tunneling light-emitting diode shows that the integrated light emission intensity increases sli...

The amount of 11s aggregate in phycocyanin, normally stimulated by hydrophobic forces, is dramatically increased by the presence of deuterium oxide. Proteins in which hydrophobic forces are not proposed as a mechanism for aggregation are unaffected by deuterium oxide. These observations are consistent with the lower critical micelle concentration reported for ionic detergents in deuterium oxide...

Guest molecules trapped within the regular voids of crystalline adducts, called inclusion compounds, are likely to experience mobility. Recent solid-state *H NMR studies indicated these motions to be primarily discrete jumps related to the molecular symmetry, to that of the environment, or to some other geometric feature of the system investigated. In this work we offer a more consistent pictur...

the two stable isotopes of hydrogen, protium (1h) and deuterium (2h) differ in their physicochemical nature. deuterium-depleted water (ddw) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted mda-mb-231, mcf-7 human breast adenocarcinomas and pc-3 human prostate tumors in vivo. the apoptosis-triggering effect of ddw was demonstrated both i...

The absolute sputtering yields of D+, He+ and Li+ on deuterium saturated solid lithium have been measured and modelled at 45◦ incidence in the energy range 100–1000 eV. The Ion–surface InterAction Experiment (IIAX) was used to measure the absolute sputtering yield of lithium in the solid phase from bombardment with a Colutron ion source. The lithium sample was treated with a deuterium plasma fr...

Deuterium dilution for the measurement of total body water (TBW) has been conducted using varying protocols for equilibration. We measured TBW from deuterium dilution in urine samples in twenty-eight subjects using three protocols: (1) early morning dosage without breakfast, measuring deuterium in a second voiding at 4 h and 6 h; (2) early morning dosage with breakfast with the same measurement...

We present recent work in the development of two new types of compact portable neutron generators, axial and field desorption, to be used for associated particle imaging and brachytherapy. The lightweight and small size of these neutron generators allow for greater versatility than current neutron sources that require heavy shielding and large spaces to operate. In these sources, neutrons are c...

Ion implantation was used to incorporate deuterium at the Si–SiO2 interface. Polycrystalline silicon gate metal-oxide-semiconductor diodes with 4 nm oxide grown on deuterium-implanted p-type ^100& silicon substrate were investigated. It was observed that deuterium implantation at a light dose of 1310/cm at 25 keV reduced oxide leakage current due to reduction in oxide charge and interface traps...

Recent experiments on the interaction of intense, ultrafast pulses with large van der Waals bonded clusters have shown that these clusters can explode with substantial kinetic energy. Producing explosions in deuterium clusters with a 35 fs laser pulse, deuterium ions were accelerated to sufficient kinetic energy to drive deuterium–deuterium ~DD! nuclear fusion. By diagnosing the fusion yield th...
