Scientists are now researching new methods for hydrogen production One of them involves use of green algae Another promising method involves the conversion of biomass derivatives such as glucose or sorbitol which can be done at low temperatures through the use of a catalyst11 Reactive MgO has advantages over OPC in production and application Firstly with regard to production reactive MgO is calcinated from magnesite MgCO 3 at a low kiln temperature less than 750 176 C compared with OPC production over 176 C thus significantly reducing the fuel consumption

3 The proliferation of backfill mining method has made backfill mechanics grow into a sub discipline under rock mechanics Cemented tailings backfill is a composite material with multiphase consisting of tailings cement and a wide variety of micro cracks micro pore air bubble etc 4 Passivation is one of the principal problems of copper electrorefining industry that can lead to a reduced production efficiency and increased power consumption The influence of additives on passivation of copper alloys and especially passivation time under galvanostatic mode is investigated by many researchers 1−4 However the corrosion form of copper alloys has not been adequately
