The technology adopts the Gibbs energy descriptor [Gδ(T)], which only needs information about the composition, enthalpy of formation and atomic density of the material. The descriptor can be used to predict the Gibbs free energy that reacts with CH4, thus obtaining the corresponding conversion....

Uranium is the ninety-second element of the periodic system. The atomic ground state is designated 5L 0 6 in spectroscopic notation and has a 1s 2 2s 2 2p
Thus, Pardeshi & Patil used a slurry batch reactor to degrade phenol using sunlight instead of UV lamps (approximately 4% UV light and 43% visible light) as an energy source to reduce operational costs. The experiments were performed at ambient temperatures in the presence of ZnO (250 mg/...
The general format for an isotope using this tool is , where X is an elemental symbol, A is the mass number, and Z is the atomic number. The Isotope tool can be used in much the same way as the Superscript and Subscript tools. The problem below asks us to complete the given ...
There are 38 isotopes of zinc, ranging in atomic weights from Zn-54 to Zn-83.Just four of these are stable, and those four, plus one naturally radioactive isotope (Zn-70) that has a very long half-life (5×10+14years), make up the element’s existence onEarth. Their proportional ...
Table 2 SMARTS atomic and bond primitives Full size table Atom and bond primitive specifications may be combined to form expressions by using logical operators. SMARTS examples can be found on Daylight's web site [43]. Because chemical pattern representations are relatively new, the number of inte...
When comparing non-porous and porous films, the highest improvements achieved were a factor of ∼7.9 in dynamic range and ∼7.3 in maximum sensitivity, followed by an improved linearity with a half-sensitivity point at 43% O2 V/V. Also, the recovery time was reduced by an order of ...
