The researchers at Purdue University in US develops a new method to purify water used in oil refinement

Researchers at Purdue University in the US, including one of Indian origin, have developed a new process to remove nearly all traces of oil in produced water — a byproduct from the oil refinery and extraction process. The process uses activated charcoal foam and subjects it to solar light to produce heat and purify the ..

US researchers identifies cost-effective method for hydrogen fuel production

Researchers from the University of Arkansas and Argonne National Lab in the US have identified more cost-effective and efficient ways of producing hydrogen fuel by splitting water. They showed that nano-particles composed of nickel and iron are better alternatives than more costly materials when used as catalysts in the production of hydrogen fuel through water ..
