Carbon nanotube–polymer composites Chemistry processing ~ Carbon nanotubes have long been recognized as the stiffest and strongest manmade material known to date In addition their high electrical conductivity has roused interest in the area of electrical appliances and communication related applications
Carbon nanotube CNT gas sensors for emissions from ~ 2 Carbon nanotubes Carbon nanotubes are seamless cylinders formed by wrapping of graphene sheets along the axial direction The ends of CNTs are sealed with fullerene like hemispherical molecules
Effect of Carboxylic Functional Group Functionalized on ~ The adsorption mechanism of the removal of lead from water by using carboxylic functional group COOH functionalized on the surface of carbon nanotubes was investigated Four independent variables including pH CNTs dosage contact time and agitation speed were carried out to determine the influence of these parameters on the adsorption capacity of the lead from water
Harvesting electrical energy from carbon nanotube yarn ~ The rise of smallscale portable electronics and wearable devices has boosted the desire for ways to harvest energy from mechanical motion Such approaches could be used to provide batteryfree power with a small footprint Kim et al present an energy harvester made from carbon nanotube yarn that converts mechanical energy into electrical energy from both torsional and tensile motion
C An Open Access Journal from MDPI ~ C an international peerreviewed Open Access journal Recently polymer electrolyte fuel cells PEFCs are attracting a lot of attention owing to their small size and relatively low working temperature below 80 °C which enables their usage in automobiles and household power generation
Space elevator Wikipedia ~ A space elevator is a proposed type of planettospace transportation system The main component would be a cable also called a tether anchored to the surface and extending into design would permit vehicles to travel along the cable from a planetary surface such as the Earths directly into space or orbit without the use of large rockets
Graphite Wikipedia ~ Graphite ˈ ɡ r æ f aɪ t archaically referred to as plumbago is a crystalline allotrope of carbon a semimetal a native element mineral and a form of coal Graphite is the most stable form of carbon under standard re it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds
Nanotube de carbone — Wikipédia ~ Découverte En 2006 un éditorial de Marc Monthioux et Vladimir Kuznetsov du journal Carbon a décrit lintéressante et pourtant méconnue origine des nanotubes de carbone Une très grande partie des revues de toute nature attribuent à tort la découverte de tubes nanométriques composés de feuillets de graphite à Sumio Iijima en 1991 1 2
Nanocomposites synthesis structure properties and new ~ ABSTRACT Nanocomposites a high performance material exhibit unusual property combinations and unique design possibilities With an estimated annual growth rate of about 25 and fastest demand to be in engineering plastics and elastomers their potential is so striking that they are useful in several areas ranging from packaging to biomedical applications
Advanced Energy Materials Early View ~ An exceptionally simple two‐step activation method mild acid oxidation followed by air calcination is implemented to create a low‐cost flexible air electrode for zinc‐air batteries from commercial carbon two‐step‐activated carbon cloth exhibits superior bifunctional oxygen electrocatalytic activity and durability
