This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...

Ostwald ripening is an evolutionary mechanism that results in micro-scale carbon spheres from nano-scale spheres. Vapor-phase carbon elements from small carbon nanoparticles are transported to the surface of submicron-scale carbon spheres, eventually leading to their evolution to micro-scale spheres via well-known growth mechanisms, including the layer-by-layer, island, and mixed growth modes. ...

nowadays, magnesia carbon refractories are very important for the iron and steel industries. it is dueto their unique properties, such as low wet ability with melt iron and steel. therefore, it is importantto extend the life of the refractory. in this research, the effect of calcined alumina and nano carbon onmechanical strength and corrosion resistance against slag in magnesia carbon refractor...

The excitement of nano-test-tube chemistry in a single-walled carbon nanotube is exemplified in our study on electron doping in carbon nanotubes. Electron doping through the 1D van Hove singularity of single-walled carbon nanotubes is realized via a chemical reaction of an encapsulated organocerium compound, CeCp3. The decomposition of CeCp3 inside the carbon nanotubes increases the doping leve...

Members of the 14-3-3 protein family are involved in many important cellular events, including stress response, survival and apoptosis. Genes of the 14-3-3 family are conserved from plants to humans, and some members are responsive to UV radiation. Despite the high rate of pollution generated by nano-pollutants, up to now their toxic effect on development is totally obscure. Embryos treated wit...

Laser desorption mass spectrometry was used in the production and analysis of gas phase metal sulfur clusters. Clusters of gas phase aluminum, gallium, and indium sulfur were produced and analyzed using a time-of-flight mass spectrometer. Also, carbon nano-onions produced by an arc between graphite electrodes in water and the annealing of nanodiamonds were analyzed. The sulfur experiments were ...

Smoke manifested ever since our ancient's lit fire; today it has evolved to become an environmental concern. However, medicinal smoke is still part of man's natural remedies, religious and cultural practices too. The Asiatic household practice of burning turmeric rhizomes to relieve nose and chest congestion is a well known yet never scientifically authenticated or studied practice. For the fir...
