Chitosan and poly(methyl methacrylate) (PMMA) composites were synthesized by polymerization with heating mechanochemical method. The obtained polymer analyzed the ATR FT-IR spectroscopy presence of intermolecular hydrogen bonds hydrophobic interactions in formation PMMA chitosan was shown.
The mechanical behaviour of UO2 single crystal is under debate due to the unexpected multi-slip observations in experiments that involve dislocations 12〈110〉{100} slip systems but also 12〈110〉{110} and 12〈110〉{111}. We propose a multi-scale model based on composite which, effect cross-slip, part dislocation density primary can be transferred secondary with lower propensity glide more favourable...
Vascularized composite allotransplantation represents a useful addition to reconstructive options available to the plastic surgeon. Though the procedure provides beneficial functional outcomes, there remain complications, often associated with the immunosuppression necessary to maintain an allograft. We report a case of eponychial fold lesions following successful bilateral upper extremity allo...
The wear resistance mechanisms of a silicon carbide (SiC) paticulate reinforced Al–Li alloy composite at 250°C by a pyramidal indenter have been studied. It is found that the subsurface damages that control the wear resistance are: generation of dislocations and cracks in the SiC particles, interface debonding between matrix and reinforcements and plastic deformation of the matrix. © 1998 Elsev...
