Scientists develop theoretical models to predict the presence of clathrate hydrates outside Earth, shedding light on the evolution of other atmospheres. Aside from regular ice, water can exist in ...

Silica clathrate compounds (clathrasils) and clathrate hydrates are structurally analogous because both materials have framework structures with cage-like voids occupied by guest species.

Polyhedron: green, 14-hedron; red, 15-hedron. Plot: gray, mixed phases found in alloys. Clathrate hydrates are complex water structures that contain foreign guest molecules inside a host water ...

Clathrate hydrates (Fig. 1) are cage-like structures of water molecules that house guest gas species. They form when the gas interacts with ice under high-pressure and low-temperature conditions ...

This coy term refers to methane hydrates, the natural-gas-and-water version of an overall category called clathrates. In a clathrate, one kind of molecule forms a scaffold or lattice that traps ...

This process is similar to clathrate hydrate formation, which occurs in water under low temperature and high-pressure conditions. However, both the enthalpy and entropy of formation of the (MeG)2(PEDS ...

Clathrate hydrates are complex water structures that contain foreign guest molecules inside a host water-molecule shell. A predicted clathrate hydrate phase structure has been stably synthesized ...

the classical approach to understanding clathrate behaviour, uses the basic expression: Figure 1: Raman spectra of the THF + H 2 double hydrates. Figure 2: Magic angle spinning 1 H NMR spectra of ...

Scientists from the United States, China, and Russia have described the structure and properties of a novel hydrogen clathrate hydrate that forms at room temperature and relatively low pressure.

Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more ...

Methane clathrate, also known as methane hydrate or fire ice, a naturally existing solid compound that brings together two unlikely companions: water and methane gas. Water molecules form a "cage" ...
