The influence of VO2(B) nanobelts on thermal decomposition of ammonium perchlorate

560--565

The influence of vanadium dioxide VO2(B) on thermal decomposition of ammonium perchlorate (AP) has not been reported before. In this contribution, the effect of VO2 (B) nanobelts on the thermal decomposition of AP was investigated by the Thermo-Gravimetric Analysis and Differential Thermal Analysis (TG/DTA). VO2 (B) nanobelts were hydrothermally prepared using peroxovanadium (V) complexes, ethanol and water as starting materials. The thermal decomposition temperatures of AP in the presence of 1 wt.%, 3 wt.% and 6 wt.% of as-obtained VO2( (B) nanobelts were reduced by 39 °C, 62 °C and 74 °C, respectively. The results indicated that VO2 (B) nanobelts had a great influence on the thermal decomposition temperature of AP. Furthermore, the influence of the corresponding V2O5, which was obtained by thermal treatment of VO2 (B) nanobelts, on the thermal decomposition of AP was also investigated. The results showed that VO2 (B) nanobelts had a greater influence on the thermal decomposition temperature of AP than that of V2O5.

The study suggests that Sirtuin 1 (SIRT1) may play an important role in the development of bovine adipose tissue in vivo. To investigate the differential mRNA expression between bovine intramuscular (IM) preadipocytes (BIPs) and subcutaneous (SC) preadipocytes (BSPs), conventional collagenasebased procedures were modified to harvest preadipocytes from the longissimus dorsi muscle and SC adipose tissue of Luxi cattle, respectively. The time-spatial expression of SIRT1 and associated genes, such as forkhead box O1(FoxO1), peroxisome proliferator-activated receptor-γ (PPARγ),insulin-like growth factor-1(IGF-1), glyceraldehydes-3-phosphate dehydrogenase(GAPDH), and leptin, during bovine preadipocyte differentiation were investigated using real-time quantitative PCR. The intracellular triglyceride concentration of BSPs increased more dramatically than that of BIPs during cell differentiation. The expression of SIRT1 and other genes occurred in the BSPs and BIPs during differentiation indicating that different mechanisms underlie the adipogenesis of BSPs and BIPs, and that the BSPs cultured in vitro show a higher differentiation capacity than BIPs.
