Underground Gas Storage in Saline Aquifers: Geological Aspects

Energies, Год журнала: 2024, Номер 17(7), С. 1666 - 1666

Опубликована: Март 30, 2024

Energy, gases, and solids in underground sites are stored mining excavations, natural caverns, salt the pore spaces of rock formations. Aquifer formations mainly isolated aquifers with significant spreading, permeability, thickness, possessing highly mineralized non-potable waters. This study discusses most important aspects that determine storage gas, hydrogen, or carbon dioxide deep aquifers. In particular, selection characterization structure chosen for storage, capacity, safety process considered. The choice is made on basis following factors criteria: geological, technical, economic, environmental, social, political, administrative–legal. geological dynamic model site then drawn based characteristics structure. Another factor choosing a its capacity. addition to type dimensions petrophysical parameters reservoir rock, capacity influenced by properties gases operating facility. Underground gas fraught technical hazards. Therefore, integrity under consideration should be documented verified. article also presents an analysis location basic facilities currently To date, there have been no successful attempts store hydrogen analogous conditions. due this which associated high requirements storage.

Green Methodologies for Tetrazole Synthesis from Different Starting Materials: A Recent Update

Current Organic Chemistry, Год журнала: 2024, Номер 28(2), С. 134 - 160

Опубликована: Янв. 1, 2024

Abstract: Tetrazole is a most versatile pharmacophore of which more than twenty FDAapproved drugs have been marketed globally for the management various diseases. In spite many remarkable and consistent efforts having made by chemists towards development greener sustainable strategies synthesis tetrazole derivatives, this approach still needs attention. The present review focuses on green synthetic preparation derivatives from different starting materials such as nitrile, isonitrile, carbonyl, amine, amide, oxime terminal alkyne functions. mechanism substrates discussed. addition to this, four component Ugi-azide reaction also described. Of note, articles exploited several water-mediated solvent-free methodologies synthesis. important key features were pinpointing in each scheme provides excellent guide those searching selective procedure achieve desired transformation. This seeks timely account (2011-2023) splendid array ecofriendly procedures known today materials. rational enlighten recent advancements substrates.

Silica Confinement for Stable and Magnetic Co−Cu Alloy Nanoparticles in Nitrogen‐Doped Carbon for Enhanced Hydrogen Evolution

Angewandte Chemie, Год журнала: 2024, Номер 136(24)

Опубликована: Апрель 10, 2024

Abstract Ammonia borane (AB) with 19.6 wt % H 2 content is widely considered a safe and efficient medium for storage release. Co‐based nanocatalysts present strong contenders replacing precious metal‐based catalysts in AB hydrolysis due to their high activity cost‐effectiveness. However, precisely adjusting the active centers surface properties of nanomaterials enhance activity, as well suppressing migration loss metal atoms improve stability, presents many challenges. In this study, mesoporous‐silica‐confined bimetallic Co−Cu nanoparticles embedded nitrogen‐doped carbon (Co x Cu 1−x @NC@mSiO ) were synthesized using facile mSiO ‐confined thermal pyrolysis strategy. The obtained product, an optimized Co 0.8 0.2 catalyst, exhibits enhanced performance turnover frequency 240.9 mol H2 ⋅ min −1 at 298 K, surpassing most noble‐metal‐free catalysts. Moreover, demonstrates magnetic recyclability extraordinary negligible decline only over 30 cycles use. This was attributed synergistic effect between Cu, silica confinement. work proposes promising method constructing hydrolysis.
