Nanoparticles (NPs) as antibiotics may help to avoid developing resistance and also these nanosized particles aid in efficient antibiotic delivery (Rai et al., 2009). Recent studies show that some metal nanoconstructs having antimicrobial activity has been effective in controlling infective diseases (Goodman et al., 2004, Schaller et al., 2004). It also holds the advantage with reduced toxicity, low cost, improved pharmacokinetic

The use of Composite Materials in Aerospace, Wind Power and Automotive Technologies Introduction A composite is a multiphase heterogeneous material comprising of fibres that are embedded in a matrix [1], [2]. A composite is unlike an alloy because in an alloy, the other components have been produced by naturally occurring changes. There is a diversity of types of composites currently available, since “it is possible to design materials with property combinations that are better than those found
