Natural Products have long been a fertile source of cure for cancer, which is projected to
become the major causes of death in this century. However, there is a continuing need for …

Superplasticity — the ability of a material to sustain large plastic deformation — has been
demonstrated in a number of metallic, intermetallic and ceramic systems. Conditions …

The mechanical behaviour of nanocrystalline materials (that is, polycrystals with a grain size
of less than 100 nm) remains controversial. Although it is commonly accepted that the …

The ability to achieve a high tensile ductility in a polycrystalline material is of interest both
from a scientific point of view and also because of potential applications in the materials …

Open field rice straw burning causes air pollution, GHGs emission (7300 kg CO 2 -equivalent
per hectare), soil nutrient and biodiversity losses and human health hazards. Huge amount …

The widespread use of superplastic forming of aluminum alloys is hampered by the slow
optimum strain rate for superplasticity, particularly in commercial aluminum alloys. In addition, …

The extraordinary mechanical, thermal and electrical properties of carbon nanotubes have
prompted intense research into a wide range of applications in structural materials, electronics…

Molecular-dynamics simulations have recently been used to elucidate the transition with
decreasing grain size from a dislocation-based to a grain-boundary-based deformation …

, fluctuations in energy in pushing the dislocation over barriers. Consequently the energy
required for activation decreases with increasing values of the stress; and therefore, for a given …

The efficiency of Bacillus subtilis DM-04 and Pseudomonas aeruginosa M and NM strains
isolated from a petroleum contaminated soil sample from North-East India was compared for …
