metal material on the high-pressure side; Φn, which is known as permeability coefficient, is a basic parameter for describing the permeation performance of gas-solid matched group; and under circumstances of molecular permeation, Φ has the same unit with the diffusion coefficient D, namely m2/...

Further, they proved the efficiency of their composite sensor material by testing the ethanol response of the sensor in the presence of toluene, NO2, NH3, methanol, formaldehyde, ethylene glycol, CO, benzyl alcohol, and acetone. Other important parameters to be considered in order to achieve a...
To enhance process viability, the conversion of gas to more valuable products than ethanol have to be developed. There have been several reported successes in expressing heterologous pathways to produce acetone, butanol, butyrate, and isopropanol, in acetogens [22,25]. Recent publication by the Whi...
of various acetogens to confirm the involvement of the acetaldehyde oxidoreductase (AOR) in ethanol production and NADPH-dependent alcohol dehydrogenase (ADH) in the hydration of acetone to isopropanol in acetogens [19]. Moreover,C. autoethanogenumhas been the subject of a multi-omics ...
Supplementary Figure17a–dshows the translational-diffusion coefficient of bulk FM and adsorbed FM systems. In adsorbed FM systems, we find that as the pressure increases, the translational-diffusion coefficient gradually increases until a certain pressure (the phase transition point), after which the ...
(Supplementary Fig.1d). Combined with electron beam evaporation technology, aluminum/photoresist/Y35oX-Quartz multilayer medium was deposited on the surface of the device (Supplementary Fig.1e). Finally, the device used acetone to remove excess photoresist, and the SAW chip with specific aluminum ...
According to Einstein's equation, the diffusion coefficient of solutes in a liquid is directly proportional to the reciprocal of the molecular radius of the diffusing solute. The Wilke–Chang expression [46] is one of the widely used empirical correlations for estimating gas diffusion coefficients ...
(rGO) nanosheets, and ultrafine CuO nanoparticles. From the obtained 3D MXene/rGO/CuO aerogel, high pyruvic sensing performance was demonstrated at ambient temperature (Fig.5b). Response of the sensor to 100 ppm of acetone was 52.09% (RT) (Fig.5b), with a response time of ~ 6.5 s...
After cooling the polymer solution to room temperature, the copolymer was precipitated by pouring the solution into acetone at room temperature, and ground up in a blender. The polymer was filtered and washed with acetone (2×). The polymer was air-dried overnight at room temperature and then...
