Wu Group Discovers New 2D Semiconductor

Nanobeam

  Nano-beam electron diffraction pattern of rhenium disulfide with a zoom-in insert image reveals a quasi-hexagonal reflection pattern. Prof. Junqiao Wu’s group has discovered a new two-dimensional (2D) semiconductor, Rhenium disulfide (ReS2). Unlike molybdenum disulfide and other well studied dichalcogenides, ReS2 behaves electronically as if it were a 2D monolayer even as a 3D bulk […]

MSE Faculty Unravel the Mechanism of Oxygen Embrittlement of Titanium

Titaniumdeffect

In the February 6 issue of the journal Science, a team of researchers led by Professor Minor and Professor Chrzan report new insights into the mechanism by which titanium is strengthened and embrittled by oxygen.  The work, which combined high-end electron microscopy characterization with first-principles theoretical calculations, establishes the key role of the interactions between […]
