Transpiration Rate Measurement Using Miniature Temperature/Humidity Sensors
Transpiration Rate Measurement Miniature Temperature Humidity Sensors
2010/9/14
A novel method for the evaluating the transpiration rate (TR) has been proposed. Miniature temperature/humidity loggers were attached onto the leaf surface of a mangrove plant, Bruguiera gymnorrhiza, ...
Effect of Relative Humidity during Storage on the Autoxidation of Linoleic Acid Encapsulated with a Polysaccharide by Hot-Air-Drying and Freeze-Drying
autoxidation encapsulation linoleic acid
2009/6/18
Linoleic acid was encapsulated with gum arabic, maltodextrin and pullulan at different weight ratios by hot-air-drying and freeze-drying. The autoxidation processes of the encapsulated linoleic acid w...
BST/Si-NPA复合薄膜的湿敏电容特性研究(Capacitive Humidity Sensing Properties of BST/Si-NPA Composite Thin Films)
钛酸锶钡 硅纳米孔柱阵列 复合薄膜 湿敏电容特性
2010/8/25
本文采用溶胶-凝胶法和旋涂工艺,以Si-NPA为衬底,制备了钛酸锶钡(BST)/Si-NPA复合薄膜,并对其形貌、结构及湿敏电容特性进行了研究。结果表明,环境的相对湿度(RH)、测试信号频率和退火温度均对湿敏电容特性具有较大影响。在100 Hz的测试信号频率下,当环境的相对湿度从11%上升到95%时,BST/Si-NPA湿敏元件的电容增量可达起始值的4 400%,显示出较高的湿度敏感性。同时,元件...
