Silicon carbide (SiC) has been used for many conventional applications that require mechanical and chemical stability at high temperatures. Mechanical stability is defined as the ability of a particular material to preserve its mechanical properties – elasticity, fracture toughness, hardness – at temperatures below and above room temperature. Chemical stability is similarly defined as the abili...

The effect of mechanical stress on Barkhausen noise from pure nickel plates is reported for as-rolled plate and plates which are annealed at various temperatures up to 1000 K. The data are compared with Vickers hardness and SEM images. The Barkhausen noise energy detected has been found generally to decrease rapidly with nominal stress except a case of a plate annealed at around 400 K. The larg...

The stability and strength of viral nanoparticles are crucial to fulfill the functions required through the viral cycle as well as using capsids for biomedical and nanotechnological applications. The mechanical properties of viral shells obtained through Atomic Force Microscopy (AFM) and continuum elasticity theory, such as stiffness or Young's modulus, have been interpreted very often in terms...

practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. however by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...

Whereas marked variations in the clinical manifestations of hereditary spherocytosis have long been recognized, we have only recently begun to define the molecular basis for this heterogeneity. An important unanswered question is whether decreased spectrin results in reduced membrane mechanical stability, and if this reduction in membrane mechanical stability can be related to in vivo surface a...

results presence of soy pc improved mechanical properties, lowered swelling ratio and increased stability of the films. solubilizing activity of phospholipid resulted in higher flux of drug release from formulation containing higher amount of soy pc. antifungal efficacy of formulations was confirmed against two species of dermatophytes in vitro. conclusions this topical composite film had the p...

To date no adequate diagnostic strategy exists for the assessment of plaque stability. Current approaches focus on identification of high-risk morphological features in cross-sectional images, such as thin caps and large lipid pools. Plaque stability, however, is a 3D mechanical problem, whose solution requires information on both the geometry and the mechanical properties of the involved tissu...
