Density of Alkali Borate Glasses
Journal of the Society of Materials Science, Japan, 1972 The densities of melts in the systems Li2O-B2O3, Na2O-B2O3 and K2O-B2O3 were measured by a counterbalanced sphere method in the temperature range from 850°to 1250°C. The room temperature densities of alkali borate glasses, i.e., Li2O-B2O3, Na2O-B2O3, K2O-B2O3, Rb2O-B2O3, and Cs2O-B2 glasses were also determined.

Boron enrichment in Martian clay [PDF]
, 2013 We have detected a concentration of boron in martian clay far in excess of that in any previously reported extra-terrestrial object. This enrichment indicates that the chemistry necessary for the formation of ribose, a key component of RNA, could have ...

Advanced Energy Materials, EarlyView.Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Advanced Energy Materials, EarlyView.The borate‐based cobalt‐iron catalyst promotes selective oxidation of water rather than chlorine evolution reaction during electrolysis of seawater. When integrated into a zero‐gap electrolyzer prototype, this catalyst supports robust splitting of artificial seawater into oxygen and hydrogen on an extended timescale.
