A YCU alumnus, Prof. Dr. S. M. Abe Kawsar, University of Chittagong, Bangladesh, published two academic books from a German publisher.

Prof. Dr. Kawsar is an honorable alumnus at Yokohama City University (YCU) who was promoted to a professor position after the completion of the Ph.D. program (2005-2009). In 2014, he was promoted to professor at the University of Chittagong, Bangladesh. Prof. Dr. Kawsar returned to YCU the next year as a visiting professor at the Japan Society for the Promotion of Science. He researched on clinical and diagnostical applications of marine invertebrate lectins and provided special lectures at YCU as visiting professor.

A superelastochromic crystal

Chromism—color changes by external stimuli—has been intensively studied to develop smart materials because of easily detectability of the stimuli by eye or common spectroscopy as color changes. Luminescent chromism has particularly attracted research interest because of its high sensitivity. The color changes typically proceed in a one-way, two-state cycle, i.e. a stimulus-induced state will restore the initial state by another stimuli.

Accurate identification of dimers from α‐pinene oxidation using high‐resolution collision‐induced dissociation mass spectrometry

Interest in mass spectrometry of highly oxidized dimers from α‐pinene oxidation has increased in the atmospheric chemistry field. Here, we apply high‐resolution collision‐induced dissociation mass spectrometry (HR‐CID‐MS) with an atmospheric pressure ionization source to investigate in detail how α‐pinene‐derived dimers are detected and identified by MS.
