Study of the Influence of TiB Content and Temperature in the Properties of In Situ Titanium Matrix Composites
(MDPI, 2017-10-27)
This work focuses on the study of the microstructure, hardening, and stiffening effect caused by the secondary phases formed in titanium matrices. These secondary phases originated from reactions between the matrix and ...

Physical proximity of chromatin to nuclear pores prevents harmful R loop accumulation contributing to maintain genome stability
(National Academy of Sciences, 2017)
During transcription, the mRNA may hybridize with DNA, forming an R loop, which can be physiological or pathological, constituting in this case a source of genomic instability. To understand the mechanism by which eukaryotic ...
