Professor Ravi Naidu is a global leader in contamination studies studying agricultural and industrial impacts on the environment. His research has led to the implementation of policy directives for governments and new technology to manage and remediate polluted groundwater and soil both in Australia and abroad.
Copper is a metal that is naturally present in the Earth s crust is essential to the development of all forms of life and has been a vital metal in the development of civilisation. It is the oldest metal used by manthe first copper coins date from 8700 BCand alloyed with tin it forms the first alloy ever used

· Among these oxidants hydrogen peroxide is the most widely used oxidant for high ODS performances owing to its high oxygen activation and environmental benevolent characteristic. 9 95 However the use of hydrogen peroxide for ODS applications requires an extra separation method afterward the oxidation reactions declining the overall
· Aqueous aggregation processes can significantly impact function effective toxicity environmental transport and ultimate fate of advanced nanoscale materials including graphene and graphene oxide (GO). In this work we have synthesized flat graphene oxide (GO) and five physically crumpled GOs (CGO with different degrees of thermal reduction and thus oxygen functionality) using

· the main barrier to producing high quality steel from recycled scrap. markets and geographical locations for a sustainable metal system. However in contrast to the regional studies mentioned stock-based projections to understand copper contamination in steel recycling. Further details of the methods and data used are given in the SI.
· Rotary blood pumps (RBPs) are successfully used in high-risk treatments but clot formation still threatens their long-term application. To reduce the risk of clot formation in-vitro thrombogenicity testing could help to improve RBP design as several studies have shown. based on the achieved quality of anticoagulation ( of INR Tests in

· The copper used for power cables is also drawn from high conductivity rod but to a thicker size than fine wires. The quality requirements are therefore slightly less stringent. The presence of any undesirable impurities can cause problems such as hot shortness which gives expensive failures during casting and hot rolling.
· Electronic waste or e-waste is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems awareness and proper regulations the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal

R. A. Kerr s News Focus story "The coming copper peak" (14 February p. 722 1 ) draws conclusions based on analyses that equate the exploitation of copper to forecasts for other commodities. The concept of peak copper is not valid because copper is used but not consumed (as is oil). As such the quantity of copper

· This process is widely used for the production of biochar because of a high solid yield (ranging from 70–80 wt at 250–300 °C to 25–35 wt at 600–650 °C) as compared to that of bio-oil and gases of which yields are maximized at a higher heating rate (Onay and Kockar 2003).
· Biomass has been long exploited as an anthropogenic energy source however the 21st century challenges of energy security and climate change are driving resurgence in its utilization both as a renewable alternative to fossil fuels and as a sustainable carbon feedstock for chemicals production.
