Scientific reports

Hossain R, Pahlevani F, Witteveen E, Banerjee A, Joe B, Prusty BG, Dippenaar R, Sahajwalla V.
PMID: 29038529
Sci Rep. 2017 Oct 16;7(1):13288. doi: 10.1038/s41598-017-13749-7.

This study identifies for the first time, the hybrid structure of the white layer in high carbon steel and describes its formation mechanism and properties. The so-called 'white layer' in steel forms during high strain rate deformation and appears...

Cancer is a systemic disease that can affect nearly every organ in the body, resulting in a progressive loss of organ function. That loss of function may be initially slow, having minimal effect, or it may be rapid, resulting...

A novel approach to simulate segregation at the centreline of continuously cast steel using laser-scanning confocal microscopy.

Journal of microscopy

PMID: 17845703
J Microsc. 2007 Aug;227:87-91. doi: 10.1111/j.1365-2818.2007.01792.x.

A concentric solidification technique was employed to simulate the segregation of alloying elements that occur during solidification at the centreline of continuously cast steel. Microstructural development of low carbon steel upon solidification has been observed in situ in a...

The next-generation short-read sequencing technologies that generate comprehensive, whole-genome data with single-nucleotide resolution have already advanced tuberculosis diagnosis, treatment, surveillance and source investigation. Their high costs, tedious and lengthy processes, and large equipment remain major hurdles for research use...
