Appl Radiat Isot. 2016 Oct;116:134-7. doi: 10.1016/j.apradiso.2016.08.003. Epub 2016 Aug 05.

The energy spectra of X-rays produced by an LiTaO3 single crystal have been measured at pressures of 1-20Pa. The energy spectra showed that the endpoint energy and the amount of X-rays gradually increased with the decrease of pressure at...

PMID: 28920976
Chem Commun (Camb). 2017 Sep 26;53(77):10640-10643. doi: 10.1039/c7cc05868c.

Various diaryl sulfides, including heteroaryl- and nitrogen-containing sulfides, have been efficiently prepared by rhodium-catalyzed odorless deborylative arylthiolation of organoborons with S-aryl thiosulfonates. The ready availability of starting materials and further transformation of sulfides have rendered a diverse range of...

Importance of metabolic rate to the relationship between the number of genes in a functional category and body size in Peto's paradox for cancer.
