Catalysis on nano - carbon materials : Going where to ? Dang

This introductory contribution to the special issue of Catalysis Today is dedicated to selected contributions presented at the Carbocat-IV (Carbon for Catalysis) Symposium held in Dalian (China) on November 7-10 (2010). The introduction first shortly overviews the main reasons for the interest on carbon materials for catalysis and the elements of novelty discussed on the contributions of this i...

Nano Characterization of Materials

Material and device characterization is challenged by continuously decreasing device dimensions placing significant demands on characterization instruments and measurement interpretation. The trend in many techniques is clearly toward characterization of smaller dimensions. Among the myriad of characterization techniques in use today, I discuss recent advances in probe microscopy, interferometr...

Nano-electromechanical Devices Robust Carbon-Nanotube-Based Nano-electromechanical Devices: Understanding and Eliminating Prevalent Failure Modes Using Alternative Electrode Materials

The International Technology Roadmap for Semiconductors (ITRS [ 1 ] ) identifi es emerging technologies with the potential to sustain Moore’s Law. A necessary succession from planar CMOS (complementary metal-oxide semiconductors) to nonplanar/dual-gate CMOS, and ultimately to novel architectures such as carbon nanotube (CNT)-based nano-electromechanical systems (NEMS) is envisioned. The ITRS al...

Low Temperature Growth of Carbon Nano-materials on Different Catalysts by the Surface-wave Plasma Technique

In this work, the microwave surface wave plasma (MWSWP) equipment is used to grow the carbon nano-materials at low temperature on different catalysts prepared by the so-called plasma assisted sol-gel synthesis method. Without any additional heating method, the plasma itself can heat up the substrate to about 280oC. By applying the -600V bias voltage, the substrate temperature can reach more tha...
