Nucleosynthesis in Thermonuclear Supernovae [PDF]
, 2017 The explosion energy of thermonuclear (Type Ia) supernovae is derived from the difference in nuclear binding energy liberated in the explosive fusion of light 'fuel' nuclei, predominantly carbon and oxygen, into more tightly bound nuclear 'ash' dominated by iron and silicon group elements.

Geostandards and Geoanalytical Research, Volume 48, Issue 4, Page 863-885, December 2024.Key Points A method is described to obtain high precision Sn isotope ratios using the double spike technique in geological reference materials containing 0.03 to 7 μg g−1 of Sn. δ122/118Sn values are reported for sixteen geological RMs. Improved precision was achieved compared with previous studies by using low concentration Sn analyte.

Geostandards and Geoanalytical Research, Volume 48, Issue 4, Page 795-805, December 2024.Key Points Isotopic reference materials are rarely cross‐examined. An optimised regression model and MC‐ICP‐MS offer a cost‐effective way to assess the reliability of values assigned to multi‐isotope reference materials. A significant lack of consistency has been observed in the long‐standing isotopic reference materials for nickel and zinc. Calibrated
