Phys.org May 22, 2024 The isoreticular principle, which allows families of structurally analogous frameworks to be built in a predictable strategies do not translate to other common crystalline solids, such as organic salts, in which the intermolecular ionic bonding is less directional. Researchers in the UK showed that chemical knowledge could be combined with computational crystal-structure prediction (CSP) to design porous organic ammonium halide salts that contain no metals. The nodes in the salt frameworks were tightly packed ionic clusters that directed the materials to crystallize in specific ways on the predicted lattice energy landscapes. The energy landscapes allowed them […]

Hydrogen battery: Storing hydrogen in coal may help power clean energy economy
Science Daily May 26, 2023 Researchers at the State University of Pennsylvania found that coal may represent a potential way to store hydrogen gas. They analyzed eight types of coals from coalfields across the United States to better understand their sorption and diffusion potential, or how much hydrogen they can hold. All eight coals showed considerable sorption properties, with low-volatile bituminous coal from eastern Virginia and anthracite coal from eastern Pennsylvania performing the best in tests. Depleted coalbed methane reservoirs’ seams contain unconventional natural gas like methane and have become an important source of fossil fuel energy over the last […]
‘Nano-chocolates’ that store hydrogen
Science Daily December 27, 2021 Storing hydrogen is costly. Researchers in Germany proposed storing hydrogen in palladium nanoparticles. To ensure that the tiny particles are sufficiently sturdy, they are stabilized by a core made of the rare precious metal iridium and attached to a graphene support. They are attached at intervals of two and a half nanometres resulting in a regular, periodic structure. When the palladium particles come into contact with hydrogen, hydrogen sticks to the nanoparticles’ surfaces, with hardly any of it penetrating inside. A small amount of heat is added to release hydrogen from the surface of the […]
