Synthesis of carbon nanotubes by chemical vapor deposition over patterned catalyst arrays leads to nanotubes grown from specific sites on surfaces. The growth directions of the nanotubes can be controlled by van der Waals self-assembly forces and applied electric fields. The patterned growth approach is feasible with discrete catalytic nanoparticles and scalable on large wafers for massive arra...

nanosized al2o3 powder is synthesized by thermal metal organic chemical vapor deposition (mocvd)combined withplasma. the effects of reaction temperature, pressure, al(ch3)3 (tma) concentration and reactant gases (co2 and o2) on the characteristics of the synthesized al2o3 powders are investigated. the experimental results demonstrate that very fineal2o3 powders with mean particle size of about ...

Low-Power Wearable Electronics In article number 2100375, Byung Jin Cho and co-workers demonstrated a novel copolymer-based flexible ReRAM device with low switching power forming-free characteristics for low-power wearable electronics. The copolymer is composed of 2-hydroxyethyl methacrylate (HEMA) 1, 3, 5 trivinyltrimethyl-cyclotrisiloxane (V3D3), fabricated via initiated Chemical Vapor Deposi...

The Atmospheric Pressure Chemical Vapor Synthesis (APCVS) route is a process that can be used for the synthesis of doped-nanocrystalline powders with very small crystallite sizes having a narrow particle size distribution and high purity. In this study, APCVS technique was used to prepare boron-doped titania nanopowders. The effects of temperature, borate flow rate and water flow rate on the am...

Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the synthesis gas, light hydrocarbons and water vapor, the liquid phase is a mixture of the h...
