(a), evaluation of H2/CH4 separation performance of high-silica CHA membrane in the presence of water vapor and light hydrocarbon impurities (b), schematic diagram of the formation of covalent linkers on substrate surface and in-situ growth of a LTA membrane (c), and the single-gas ...
Additionally, compared to other elements, transition metals are more prone to forming weaker covalent bonds with hydrogen atoms. [19], [20]. At the same time, the addition of transition metals can also weaken the interaction of the Mg-H bond and extend the Mg-H bond [21], [22]. ...
Generally, a three-state diagram, which consists of an initial state H+ + e−, an intermediate adsorbed H*, and a final product ½H2, is utilized to summarize the whole HER process. The Gibbs free energy of the intermediate state, |ΔGH*|, is considered a major indicator for ...
and Rutile-RhO243in Fig.1ishow the scattering profile as a function of the radial distance from the central absorbing Rh atom. The first peak at approximately 1.7 Å is assigned to Rh-O coordination, as found in Rutile-RhO243(blue line) and P-Tri-RhO2(black line), which have a ...
well-known components or methods are not described in detail or are presented in simple block diagram format in order to avoid unnecessarily obscuring the present invention. Thus, the specific details set forth are merely exemplary. Particular implementations may vary from these exemplary details and ...
The diagram in the top panel illustrates the structure of mammalian rDNA genes and regions analyzed by ChIP. The ChIP data were shown as percentage of input. Also analyzed were pol I transcription factor UBF and acetylated H3. Results are shown as mean ± SEM (n = 3). (B) ABH2-...
