The structural, electrical and optical properties of ZnO/Al2O3 multilayer deposited on PET substrates by RF sputtering
Khazamipour, N.; Kabiri-Ameri-Aboutorabi, Sh.; … - In: Renewable Energy 49 (2013) C, pp. 275-277
In this work ZnO/Al2O3 multilayer is deposited on PET(polyethylene terephthalate) substrate by RF sputtering in argon … atmosphere and the effect of Al2O3 layer on optical, electrical and structural properties of ZnO is investigated. It is observed … that the presence of Al2O3 layer between ZnO and PET reduce the transmission of light from ZnO/Al2O3/PET structure 11% but …

Analysis of coffee cut-stems (CCS) as raw material for fuel ethanol production
Triana, Cristian F.; Quintero, Julián A.; Agudelo, … - In: Energy 36 (2011) 7, pp. 4182-4190
Coffee cut-stems (CCS) represent a promising candidate for fuel ethanol production in tropical countries because of their high availability and high biomass yield per hectare. In this work, pretreatment of this agricultural residue with dilute sulfuric acid and liquid hot water (LHW) was...
