Growth and characterization of high-quality bulk hexagonal boron nitride crystals
While hexagonal boron nitride (hBN) in polycrystalline form has met demand for its mechanical, chemical, and thermal applications, its new electronic, optoelectronic, and nanophotonic applications required single crystals with low residual impurity concentrations. Grain boundaries and impurities …

B isotope variations at variable scales in arc volcanoes: a case study of lavas from Paniri and Toconce, Northern Chile
… the subducted oceanic slab in subduction zones. Boron (B) is an ideal geochemical tracer for the hydration of the overlying mantle wedge at subduction zones. The boron isotope composition of magmas is useful in detecting and quantifying the exchange process between the slab and the mantle. This …

POPULATION DYNAMICS AND GEOCHEMISTRY OF BENTHIC AND PLANKTONIC FORAMINIFERA TO INTERPRET THE PALEOCEANOGRAPHIC CHANGES ACROSS THE CENOMANIAN-TURONIAN OCEANIC ANOXIC EVENT 2 AT LOW AND HIGH LATITUDES
… changes across the OAE 2. In addition, boron isotopes analysis on foraminiferal tests of DSDP Site 463 and of IODP Sites U1513 and U1516 have been conducted to obtain information about ocean acidification across the OAE 2. Samples at low and high latitudes show a continuous foraminiferal …

Boron as a tracer for material transfer in subduction zones
… Front zum Back-arc wird als Resultat einer Borisotopenfraktionierung einhergehend mit einer stetigen Abnahme der Fluidkomponente und einer relativ konstanten krustalen Kontamination, die sich durch relativ gleichbleibende Sr, Nd und Pb Isotopenverhältnisse ausdrückt, interpretiert. Weil die …
