In this paper, We use a novel principle to detect acceleration and report how I-V characteristics and piezoresistance coefficient of AlGaN/GaN HEFT-micro-accelerometer are affected by setting different temperatures. It is shown that saturation current of device would go down if the temperature goes up, which is about 0.028mA/°C, based on the research. However, the device can work well at the temperature range of -50°C to 50°C, which indicates that it can work safely in the larger temperature range.

In the present work, the chemical pretreatment as well as micellar-enhanced ultrafiltration for refining canola oil miscella was investigated. The research has been conducted on adding chemical agents (CaCl2, EDTA and SDS aqueous solutions) to canola oil miscella before ultrafiltration through polyvinylidene fluoride (PVDF) membrane with molecular weight cut-offs (MWCO) 100kDa and 50kDa in a magnetically stirred flat membrane cell. Results showed that SDS solution lowered phospholipids content almost completely. The reduction of phenolic compounds in SDS- and EDTA-pretreated filtered oil was more noticeable than in the processed miscella. On the contrary, the reduction of FFAs was more in the miscella filtered without any chemical agents. The membrane exhibited no appreciable affinity towards tocopherols and carbonyl compounds in the oil samples. SDS and EDTA played an important role in oil oxidation, so that they led to increase in peroxide value.
