Researchers worldwide are actively investigating safer alternatives for the storage of natural gas—solidified natural gas (SNG), or natural gas hydrates, may just be the answer. These gas hydrates, however, are currently limited to the small scale of bench-top laboratory experiments. To that end, Professor Praveen Linga from the Department of Chemical and Biomolecular Engineering at the College of Design and Engineering, National University of Singapore, is working on advancing SNG technology for industrial viability.

Add water to ouzo liquor, and it turns cloudy. This “ouzo effect” is an example of an easy way to make highly stable emulsions but nobody has yet fully understood how it works. Now, researchers report in ACS Central Science that the secret may lie in the unique structure of the emulsion’s droplets.
The injection of bubbles from waves breaking in turbulent and cold high-latitude regions of the high seas is an underappreciated way in which atmospheric gases are transported into the interior ocean. An improved mechanistic understanding of gas exchange in high latitudes is important for several reasons, including to better constrain climate models that are used to predict changes in the ocean inventory of key gases like oxygen and carbon dioxide.
A novel compound that has the potential to starve the bacteria that causes tuberculosis – the world’s leading infectious killer after SARS-CoV2 – is entering human clinical trials.
Electrons in magnetic solids feel each other as an effective magnetic field that forces the electrons’ spins to align. If the arrangement of atoms is not fully symmetric, an additional magnetic force known as Dzyaloshinskii-Moriya Interaction (DMI) can emerge, forcing the spins to reorient and form whirling patterns called skyrmions. Researchers joined two different materials to enable skyrmion generation.
Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers.

However, they found no evidence for the same process occurring in serine clusters. In that work they concluded that if two serine molecules can bind together to form a dipeptide, then the next stages of polymerization could probably occur readily.
