Advanced Photocatalysts for CO2 Conversion by Severe Plastic Deformation (SPD). [PDF]
Excessive CO2 emission from fossil fuel usage has resulted in global warming and environmental crises. To solve this problem, the photocatalytic conversion of CO2 to CO or useful components is a new strategy that has received significant attention. The main challenge in this regard is exploring photocatalysts with high efficiency for CO2 photoreduction.

Evaluating the flow processes in ultrafine-grained materials at elevated temperatures
When polycrystalline materials are tested in tension at elevated temperatures, the flow mechanisms depend upon various parameters including the temperature of testing, the applied stress and the material grain size.

Formation of ultrafine-grained (UFG) structure and mechanical properties by severe plastic deformation (SPD) [PDF]
Commercial pure cooper (99,9% Cu) was deformed by equal channel angular pressing (ECAP) using up to 10 passes, route C. The evolution of microstructure and fracture character were observed by OM, SEM and TEM. The mean grain size decreased with increasing
