ZrO2-COATED SiC NANOWIRES PREPARED BY PLASMA-ENHANCED ATOMIC LAYER CHEMICAL VAPOR DEPOSITION

TAK, YOUNGJO; YONG, KIJUNG - In: Surface Review and Letters (SRL) 12 (2005) 02, pp. 215-219

Plasma-enhanced atomic layer deposition (PE-ALCVD) of ZrO2 was performed to coat SiC nanowires and prepare a SiC-ZrO2 core-shell nanowire structure. Zirconium tertiary butoxide (ZTB) and hydrogen plasma pulse cycles were used to grow ZrO2 films. The growth temperature of ZrO2 PE-ALCVD was 150°C...

The nanometer magnetic solid base catalyst for production of biodiesel

Liu, Chang; Lv, Pengmei; Yuan, Zhenhong; Yan, Fang; Luo, Wen - In: Renewable Energy 35 (2010) 7, pp. 1531-1536

Nanometer magnetic solid base catalysts were prepared by loading CaO on Fe3O4 with Na2CO3 and NaOH as precipitator … recovery rate of the nanometer magnetic solid base catalysts are much better than those of CaO. Calcination temperature was …

Continuous catalyst-free biodiesel synthesis from rice bran oil fatty acid distillate in a microreactor

In: Energy Reports 6 (2020) 2, pp. 545-549

This work proposed the catalyst-free biodiesel synthesis from the low-grade feedstock. Rice bran oil fatty acid distillate (RBOFAD) containing 65.5% of free fatty acids and ethanol were applied as a feedstock. The influence of operating parameters including residence time, reaction temperature,...
