Aug 25, 2015: New research has found that water molecules react differently to electric fields, which could provide a new way to study spin isomers at the single-molecule level. Water molecules exist in two forms or 'isomers', ortho and para, that have different nuclear spin states. In ortho-water, the nuclear spins are parallel to one another, and in para water, the spins are antiparallel. The conversion of ortho water into para-water and vice-versa is relevant to a broad range of scientific fields from nuclear magnetic resonance (NMR) to astrophysics.

Aug 5, 2015: One big problem faced by electrodes in rechargeable batteries, as they go through repeated cycles of charging and discharging, is that they must expand and shrink during each cycle -- sometimes doubling in volume, and then shrinking back. This can lead to repeated shedding and reformation of its "skin" layer that consumes lithium irreversibly, degrading the battery's performance over time. Now researchers have found a novel way around that problem: creating an electrode made of nanoparticles with a solid shell, and a "yolk" inside that can change size again and again without affecting the shell.

Thanks to their low weight, high energy density and slower loss of charge when not in use, these have become the preferred choice for consumer electronics. Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four-times that of lead acid. Despite being a superior consumer battery, lithium-ion batteries still have some drawbacks. Current manufacturing technology is reaching the theoretical energy density limit for lithium ion batteries and overheating leading to thermal runaway i.e. "venting with flame" is a serious concern.
