Anthocyanin biosynthesis is induced by low temperatures in a number of plants. However, in peach (cv Zhonghuashoutao), anthocyanin accumulation was observed in fruit stored at 16°C but not at or below 12°C. Fruit stored at 16°C showed elevated transcript levels of genes encoding anthocyanin biosynthetic enzymes, the transport protein glutathione S‐transferase and key transcription factors. Higher...
Partial Discharges (PDs) are one of the most severe threats to electrical insulations, while the failure of which turns out to be the main cause of power equipment outages. PD activity is related to different mechanisms, and out of which the change of temperature will influence it greatly. In order to study the effect of temperature on PD characteristics, a needle-plane oil-paper insulation model...
Oil-paper insulation is widely used in power transformers. Thus, its insulation quality, aging included, has a strong impact on the operation of power transformer. The purpose of this paper is to evaluate oil-paper insulation's aging condition more reliably. The frequency domain spectroscopy of several oil-immersed paper samples with different aging conditions were measured at 25°, 60°, 90° and 120°...
The dye-sensitized nanocrystalline TiO2 film solar cells were fabricated here. The TiO2 electrodes were prepared by a sol-gel process and were sensitized by the nature dye extracted from a paper mulberry tree. When the sintering temperature of TiO2 films rises from 90 to 500 °C, the energy conversion efficiency of the solar cell improves considerably and up to an optimum value at 470 °C. To investigate...
The research objectives of the study are to manufacture nano-TiO2 with doping Fe3+, Ce3+ and La3+ adopting impregnation method, examine the effects of the preparing condition on catalyst performance, and explore the influence of the adding account of metal ions and different ion-combinations on the photocatalytic activity of modified nano-TiO2. The experiment results support the following three conclusions...
We present a substrate transfer technology which allows devices to be fully processed using conventional silicon-based fabrication techniques prior to their integration with parylene. A parylene-based metal microelectrode array with high-temperature silicon oxide passivation layers was demonstrated. Combining high quality devices from well-established processes with thin, flexible and biocompatible...
The melt-electrospinning setup was designed in this paper. The temperature of every part in the setup,, including injector, nozzle, spinning space and collection target can be measured accurately by thermocouple or infrared radiation thermometers. The study on phenomena and properties of exploration for melt-electrospinning based on the novel device was conducted. The polypropylene was chosen for...
How serious damages to the transmission lines and how safe transportation of electric energy are decided by the galloping extent of transmission lines. Random wind load due to the air flow, the temperature thermal stress as a result of the changed temperature, electromagnetic forces because of transmission lines current are important factors which lead overhead transmission lines to gallop. This article...
Smart sensors are the key components of pervasive computing networks. The fiber Bragg grating (FBG) can be composed of the distributed sensing networks for the high sensitivity. The cross-sensitivity is the intrinsic problem of FBG sensors. We analyzed the influence of the measurand-strain (or temperature) effect on temperature (or strain) in fiber-optic sensors that employ FBGs. Based on the mode-coupling...
