Researchers Find New Way to Control Light with Electric Fields
Researchers Control Light Electric Fields
2017/7/20
We report that the refractive index of transition metal dichacolgenide (TMDC) monolayers, such as MoS2, WS2, and WSe2, can be substantially tuned by > 60% in the imaginary part and > 20% in the real p...
高电压脉冲电场下的牛骨胶原蛋白酶法提取（Enzymic Method Extraction of Collagen from Bovine Bone by High Intensity Pulsed Electric Fields）
牛骨 胶原蛋白 高电压脉冲电场
2010/12/29
将高电压脉冲电场（PEF）技术用于牛骨胶原蛋白的提取，通过单因素试验和Box-Behnken中心设计法得出提取牛骨胶原蛋白的最佳工艺参数为：底物质量浓度1.0g/(100mL)、胃蛋白酶添加量3%、pH值2.5、场强21.98kV/cm、脉冲数7，在此条件下，可溶性蛋白质量浓度高达16.21mg/mL，通过紫外光谱鉴定了所提取的样品为纯胶原蛋白而不含其他杂蛋白。
高压脉冲电场对蛋清单增李斯特菌的杀灭效果（Synergistic Effect of Pulsed Electric Fields on the Inactivation of Listeria innocua in Egg White）
高压脉冲电场 蛋清 李斯特菌
2009/8/11
研究了高压脉冲电场（PEF）与温和热协同处理对蛋清中嗜冷菌——单增李斯特菌的杀灭效果。结果表明，当处理温度为15℃时，20、25、30和35kV/cm电场强度作用400μs，每1mL蛋清所含李斯特菌数分别降低了0.8、1.4、2.3和3.8个数量级。当处理温度升至55℃时，每1mL蛋清总菌数分别降低了1.3、2.5、4.9和6.4个数量级。当处理温度为15℃，35kV/cm作用100、200、30...
Effect of Pulsed Electric Fields on the Main Chemical Components of Liquid Egg and Stability at 4°C
egg lipids proteins pulsed electric field structure
2014/3/10
The effect of PEF on the whole liquid egg components, proteins and lipids, and the microstructure were studied and compared with pasteurisation. The effect of the refrigerated storage one week after t...
Properties of constricted 2DEG/metal structures in microwave electric fields
2DEG structures microwave electric fields microwave detector
2011/4/27
Detection properties of asymmetrically constricted 2DEG/metal junctions were investigated at 10 GHz frequency at room and liquid nitrogen temperature. Operation of such detectors is based on non-unifo...
Effect of Ordinary Frequency High Electric Fields on Evaporation and Drying
high electric fields evaporation drying
2010/11/22
Evaporation of water was enhanced by ordinary frequency (60 Hz) high electric fields (HEF), and the effect was directly proportional to the extent of treatment, i.e., increased with time and electric ...
