Collaboration uses Lehigh's advanced electron microscopes to pinpoint phase transition Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities? The phenomenon, known as liquid metal embrittlement, or LME, has baffled metallurgists for a century. Now, a team of ceramics researchers has shed light on LME by obtaining atomic-scale images of unprecedented resolution of the...

YANG Nan, MAO ZongWan and SUN HongZhe et al., at the Department of Chemistry, University of Hong Kong and Sun Yat-sen University have characterized a series of bismuth citrate complexes by X-ray crystallography and modeled the structure of ranitidine bismuth citrate, a medicine used widely for the treatment of peptic ulcer and gastric reflux disease. The polymeric framework of bismuth citrate may serve as a "drug carrier" for delivery of other drugs in the human body. This significant...
