Development of a hydroprocessing catalyst containing Boron and Nano-boron compounds

Yonel-Gumruk E., Meric Kartal Berker A., Özcan O., Nilgün Akin A., Turkish Petroleum Refineries Corporation, US

Hydroprocessing is a refinery process of catalytic cracking and hydrogenation of petroleum in order to convert low value heavy hydrocarbons into high value light hydrocarbons and to remove sulphur, nitrogen, oxygen and metals to the [...]

Tuning the Gas Pressure Discharge of Nanoenergetic materials by Boron and Carbon Nanotube Additives

Martirosyan K.S., Wang L., Luss D., University of Texas at Brownsville, US

Thermite reactions are highly exothermic and may rapidly release high amount of stored chemical energy in the form of heat, light and wave. Nanothermite formulations that use aluminum or magnesium as the reducing agent and [...]

Atomistic Modeling for Boron Diffusion in Strained Silicon Substrate

Kim H-G, Kim J-S, Kim Y.K., Yoon K-S, Kim H-G, Kim J-S, Kim Y.K., Kim H-G, Kim J-S, Kim Y.K., Won T., Inha University, KR

We report our KMC study on the effect of strain on B diffusion in silicon and relaxed SiGe layer by assuming a virtual strained structure with charged defect energy and diffusivity. The simulation results imply [...]

Kinetic Monte Carlo Study on Silicon Pre-Implant Technique

Kim J-S, Kim Y.K., Kim J-S, Kim Y.K., Yoon K-S, Won T., Inha univ., KR

In this work, we investigated the effect of Si pre-implantation on the low energy B implant and boron activation enhancement during the post-implant annealing process using KMC. For investigating Si pre implantation effect, Si implantation [...]

Conductivity of the Crystalline Boron Nanowires Measured in TEM

Lourie O., Gatan Inc., US

In this experiment we report on using in-situ STM-TEM system and EELS to characterize the electronic properties of the boron nanowires. We use low loss EELS approach to study the band structure and the dielectric [...]

Preparation of BN-Si3N4 Nanostructured Composites

Krushinskaya L.F., Makarenko G.N., Uvarova I.V., Timofeeva I.I., Isayeva L.P., Institute for Problems of Materials Science NAS of Ukraine, UA

The process of boron silicide nitration in nitrogen and ammonia media has been studied. The products of nitration were established the composite powders of boron and silicon nitrides. By using the boron silicide compounds instead [...]

Boron Diffusion and Activation in Silicon in the Presence of Other Species

Li H-J., Kohli P., Ganguly S., Kirichenko T.A., Zeitzoff P., Torres K., Banerjee S., Univ. of Texas Austin, US

Modeling and experimental investigation of B equilibrium diffusivity and its activation in Si in the presence of other species, including ab initio calculations, are presented here. The results suggest that incorporating other species along with [...]

Modeling of Strain in Boron-Doped Silicon Cantilevers

Rueda H.A., Law M.E., University of Florida, US

A finite element method is developed to compute the mechanical strain resulting from boron doping in silicon. This technique is then applied to the bending of borondoped silicon cantilevers. The silicon cantilever is modeled as [...]
