Summary: This study investigates the detrimental effects of high-pressure hydrogen gas on metals, focusing on understanding the mechanisms and driving forces of hydrogen absorption. A new generalized form of Sievert's law is derived and validated with experimental data, parametrizing the equation for different metals. The role of microstructural trapping sites in parameter identification is discussed, and the parametrized equation is applied to calculate stress-enhanced hydrogen solubility in practical engineering scenarios.

Summary: Selenium in gaseous form is difficult to retain in solid phases during coal combustion due to its high saturated vapor pressure. Understanding the migration of SeO2(g) on ash particles in the low-temperature zone is essential for controlling selenium emission. The physically-bound Se in fly ash consists of selenium condensation and physical adsorption, with mullite showing the best performance in selenium capture at temperatures between 90-200 degrees C.

Summary: This study reports the first observation of diffusion anisotropy of gaseous helium-3 in ordered aerogels at 4.2 K. The origins of the anisotropy in aerogels of different porosity are discussed, and correlations between gas diffusion coefficient and basic aerogel parameters are examined using diffusion simulations. The failure of certain diffusion models in both isotropic and anisotropic aerogels at low temperatures is observed, and the effect of a wall attractive potential on gas dynamics is believed to be crucial in explaining the observed diffusion behavior.

Summary: MnOx catalysts with 3D structure (Mn-HT) were prepared using KIT-6 as a template by the hard-template method, and their catalytic performance for the selective catalytic reduction of NOx by NH3 was investigated at low temperatures. It was found that the template KIT-6 prepared at different hydrothermal temperatures significantly affected the catalytic performance of Mn-HT catalysts. Among them, Mn-140 catalyst prepared using the template obtained at a hydrothermal temperature of 140 degrees C exhibited the highest catalytic performance. Characterizations showed that Mn-140 catalyst possessed high reducibility with abundant surface oxygen species and Mn4+ species. NH3-TPD and in situ DRIFTS demonstrated that there were more Lewis acid sites and Bronsted acid sites on the surface of Mn-140 catalyst, promoting the adsorption and activation of NH3 and efficiently reducing NOx mainly by the Eley-Rideal (E-R) mechanism, accompanied by the Langmuir-Hinshelwood (L-H) mechanism.

Summary: The study investigated the influence of sputtering power, film thickness, and sputtering working pressure on the adsorption capacity and photocatalytic activity of MoO3 thin films. The results indicated that the samples deposited at 60 W and 12.0 mTorr with a thickness of 400 nm exhibited the maximum adsorption and photocatalytic performances. Raman spectroscopy and photoacoustic spectroscopy experiments confirmed strong MB adsorption on the film surface, with a hypsochromic shift indicating MB aggregation on the MoO3 surface.

These results suggest that ZnMn2O4 can be a promising sensing material for isopropanol vapor.
