A boron isotope study combined with analyses of elemental boron, lithium, and chlorine is used to suggest that brines from the Dead Sea and on-shore hypersaline thermal springs (Hamme Yesha, Hamme Zohar, and Hamme Mazor) are the products of interaction of evaporated seawater with detrital sediments. The high 6”B values of the Dead Sea brines (55.7 to 57.4%0 versus NBS-951) and the hot springs (...

The absorption of the H2S on the small boron nitride fullerene (B12N12) and its Al-inserted analog was theoretically analyzed by density functional theory. The structural stability was based on the minimum energy and non-complex vibrational frequencies. Different sites and orientations of H2S, using the monomer unit, were considered. Compared with the...
