·Si/Cu 3 Si/Cu composite particles were successfully fabricated by a feasible cost effective Copper on the surface of each particle provides good conductivity among the particles • Cu 3 Si eliminates contact electric resistivity between copper and silicon thus enhances conductivity The anode materials exhibit excellent electrochemical
·For high effciency microwave absorption CNTs need to possess sufficient EMW loss capacities and also meet the requirement of impedance match To improve the impedance matching behavior of CNTs incorporating magnetic lossy materials including magnetic metal ferrite and carbonyl iron [ 8 10 ] is a common method because it directly affects
·Herein we propose a hybrid solar cell comprising of a SiO x /nc SiO x n stack on the rear end and an a Si H i/p stack on the front To reduce optical and parasitical absorption nc SiO x n a wide bandgap material has been developed to replace doped poly Si The carrier selectivity surface passivation optical transmission and electrical characteristics can be
·Only for industrial processes solar heat production of 2 Gkw h is estimated and about 13% of the total heat demand of this sector Mekhilef et al 2011 is below 100 °C According to these figures there is a potential of saving CO 2 emissions of about 450 MTon/year for natural gas due to the solar heat production at low temperatures
·For example comminution consumes 53% of the total energy in the whole process from mining to mineral processing and the comminution cost is as high as 67% of the total cost in the process whereas the cost of drilling and blasting is only 5% Spathis 2015 Another reason is that the energy efficiency of comminution is extremely low as
