Although bacterial leaching of sulphidic minerals is a well-known phenomenon, it is only in the last ten years that full-scale bacterial leaching plants have been commissioned for gold processing. In order for bacterial ...

Heavy metals are released into the environment either by natural processes or by anthropogenic activities. Industries such as leather tanning, textiles, metallurgical, electroplating and mining activities discharge the ...

Efficient exploitation and conservation of the oceans poses great technological challenges for scientists and engineers who must develop materials, structures and equipment for use in harsh environment of the oceans. For ...

Bulk metallic glasses (BMGs) possess very attractive mechanical properties like high yield strength (~ 2 GPa), high elastic strain limit (2 %), and good corrosion resistance. BMGs display fracture toughness values (in mode ...

Renewable energy becomes inevitable for future energy needs. Accordingly, researchers are exploring possible alternatives to conventional fuel based internal combustion engines. In recent years, Bio-fuel (methane/ethanol) ...

There has been growing interest in designing and development of suitable micro or nano drug delivery system with the ability to target site specifically and release the payload in a predetermined fashion. Recently a new ...

The removal of toxic and heavy metal contaminants from aqueous waste streams and industrial effluents is one of the most important environmental issues being faced the world over. In order to combat this problem, the ...

A gradual depletion of high-grade ores, coupled with the growing demand for mineral commodities across the world has culminated in the increased exploitation of lean-grade ores with complex mineralogy. The mineral processing ...

Aluminium alloys, which are the most widely used materials in the aircraft and aerospace industries, find their applications due to high strength–to-density ratio, resistance to catastrophic fracture, high degree of ...
