The response time of PTND3 sensor towards 100 ppm NHis only 3 s at room temperature (RT). Meantime, the response and response time of the PTND3 to the NHis 1 and 14s even at the concentration of 100 ppb. Therefore, the ordered Pd@TiONFs array NHsensor display great potential for ...
;CONSTITUTION: An element body in which apatite particle whose impedance is changed depending on the presence of carbon dioxide gas at room temperature by regulating chlorine ion content is molded into a plate is used. The apatite particle is a pelleted particle formed by mixing apatite slurry ...
Development of fast highly-sensitive semiconductor gas sensors operating at room temperature, which would be compatible with semiconductor technology, remains a challenge for researchers. Here we present such sensor based on a nanoscale Pt–TiO2–Pt sandwich. The sensor consists of a thin (∼30 nm...
product was dispersed in methanol and agitated at room temperature for 1 day, which allowed for the removal of DMF or water as guest molecules in the MOF. Vacuum filtration was applied for the removal of methanol. The powder sample was dried in a convection oven at 100 °C for 1 day....
Room temperature is a temperature at which most people would feel comfortable in an indoor setting. Typically, room temperature is in the range of 20–22 °C. At lower and higher temperatures, the characteristics of real gases deviate significantly from ideal gases. There are two main rules ...
We used gas-filled ducts as acoustic waveguides to transmit sound between the cavity at high temperatures and the acoustic transducers at room temperature. ... K Zhang,XJ Feng,K Gillis,... - 《Philosophical Transactions of the Royal Society A Mathematical Physical & Engineering Sciences》 被引量...
Left: Room temperature (25 °C experiment, Right: Experiment at elevated temperature (200 °C). Full size image It is obvious at first glance at the two plots in Fig. 5 that the chosen experiment parameters are very suitable for the characterization of the aerosol gas exchange system, ...
Electrical transport properties of the 0.3% BLSO/LIO interface at room temperature. (a) Conductance (σs) as a function of the LIO thickness, (b) sheet carrier density (n2D) as a function of the LIO thickness. The inset is the schematic cross-sectional diagram of the processed device str...
Thus, the minimal H2 content can be calculated to be 4.5 × 10−5 mg at room temperature (20°C) under one bar pressure. This is equivalent to a Li-metal particle with a radius of ∼50 μm (approximately 2.8 × 10−4 mg) plated on the graphite anode, which can result in ...
