A Device for Regulating the Temperature of Incubators Either above or below Room Temperature
I t is frequently desirable in studying the effect of temperature on living organisms to have a convenient means of regulating the temperature of an incubator or series of incubators within the range of from 5-40°C. For this purpose it is essential to have a regulating device which is reliable over long periods of time with a variation of 0.2-0.3 ° . As far as the author is aware no convenient ...
متن کاملHighly sensitive H2S sensors based on Cu2O/Co3O4 nano/microstructure heteroarrays at and below room temperature
Gas sensors with high sensitivity at and below room temperature, especially below freezing temperature, have been expected for practical application. The lower working temperature of gas sensor is better for the manufacturability, security and environmental protection. Herein, we propose a H2S gas sensor with high sensitivity at and below room temperature, even as low as -30 °C, based on Cu2O/C...
متن کاملRoom-Temperature Ballistic Nanodevices
One of the most important physical parameters to describe the quality of a piece of semiconductor material is the electron scattering length le. Also referred to as the mean-free path, it stands for the average distance between the randomly distributed scatterers in the material, such as lattice defects, impurities, and phonons. The electron mean-free path is typically a few nanometers (1 nm = ...
متن کاملRoom Temperature Ionic Liquids
The initial objective of this project was to carry out a fundamental study of the transport characteristics of a variety of gases and organic solutes in room temperature ionic liquids. The goal was to combine information collected from a number of different experimental measurements in order to develop a fundamental understanding of the interactions governing transport in ionic liquids. Measure...
متن کاملHydrogenated Products at Room Temperature
Reduction of nitrobenzene, 4-ethyl nitrobenzene, 4-isopropyl nitrobenzene, 4-nitro 1-phenyl acetate, acetophenone, with CuCl2/MeOH/NaBH4 provided hydrogenated products in quantitative yields. In order to evaluate the best catalytic systems various transition metal catalysts were examined for the first time and CuCl2 catalysts was superactive system. And a solvent system was also studied with me...
