INTRAAORTIC BALLOON PUMP COUNTERPULSATION AUGMENTS THE BENEFITS OF REPERFUSION ON LEFT VENTRICULAR MECHANOERGETICS - EXPERIMENTAL STUDY
Oxygen source-oriented control of atmospheric pressure chemical vapor deposition of VO2 for capacitive applications
Vanadium dioxides of different crystalline orientation planes have successfully been fabricated by chemical vapor deposition at atmospheric pressure using propanol, etha-nol and O2 gas as oxygen sources. The thick a-axis textured monoclinic vanadium dioxide obtained through propanol presented the best electrochemical response in terms of the highest specific discharge capacity of 459 mAh g-1 with a capacitance retention of 97 % after 1000 scans under constant specific current of 2 A g-1

Ternary organic solar cells incorporating zinc phthalocyanine with improved performance exceeding 8.5%
Summarization: Ternary organic photovoltaic devices have been fabricated, by introducing for the first time, a soluble zinc phthalocyanine (ZnPc) small molecule into the poly-({4,8-bis[(2-thylhexyl)oxy]benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl] thieno[3,4-b] thiophenediyl}) (PTB7):[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) active layer. The ZnPc acts as an electron cascade material, providing an efficient energy level offset between the polymeric donor (D) and the fullerene derivative acceptor (A), enhancing charge transfer, reducing exciton recombination and thus improving the photovoltaic performance of the devices. The fabricated ternary organic solar cells of the structure ITO/PEDOT:PSS/PTB7:ZnPc:PC71BM/Ca/Al led to a champion power conversion efficiency (PCE) of 8.52%, increased by ∼15% compared to the reference binary cell.Presented on: Dyes and Pigment
