Direct liquid injection, Chemical vapor deposition, Copper foil, Graphene This study purposes to optimize Cu foil substrate surface for the CVD growth of graphene. We employ chemical pretreatments and thermal annealing at high temperature to modify surface morphology and crystal orientation of the Cu foil. Initially, we remove oxide on
Diamond thin films are grown on silicon substrates by only using methanol and argon mixtures in microwave plasma chemical vapor deposition (MPCVD) reactor. It is worth mentioning that the novel strategy makes the synthesis reaction works smoothly without hydrogen atmosphere, and the substrates temperature is only 500 °C.

fluidized-bed furnaces to eliminate about half of the sulfur and to oxidize the associated iron. The hot calcine, plus flux, is smelted in natural gas or coal-fired reverberatory furnaces operat-ing at about 1200 °C (2200 °F) to produce a furnace matte that is enriched in nickel and a slag for discard. The furnace matte is trans-
It is widely used in daily life, mainly in the steel industry, metallurgical industry, and electronic industry. High temperature sintering furnace is mainly used for sintering of ceramic powder, ceramic insert and other zirconia ceramics. Sintering of diamond saw blades can also be used for heat treatment of copper and steel strip annealing.
Infra-red absorption bands of cobalt containing CVD diamond films M. A. Neto, C. J. Tang, A. J. S. Fernandes, E. Pereira Physics Dept., University of Aveiro, 3810-193 Aveiro, Portugal Impurity contamination in polycrystalline diamond during growth is a very important issue to consider for any chemical vapor deposition (CVD) technique.
Overview The cover story of R. A. Freitas Jr. in the Journal of the American Dental Association more than a decade ago  introduced the term nanodentistry to a larger community. He developed visions effectively using dental nanorobots for orthodontic realignments, for dentition regeneration procedures and, ﬁnally, oral health maintenance.

The sintering process was executed in the inert atmosphere of argon at 1450°C with a 2-hour dwell time at the maximum temperature. Density and strength measurements of the green bodies and sintered samples were made. In order to determine the phase structures before and after the sintering process, X-ray analysis was conducted.
Metallic biomaterials like stainless steel, Co-based alloy, Ti and its alloys are widely used as artificial hip joints, bone plates and dental implants due to their excellent mechanical properties and endurance. However, there are some surface-originated problems associated with the metallic
