5th Kanto Area Spin Chemistry Meeting 2019 

Special Project Researcher Lewis Martyn Antill and Associate Professor Kiminori Maeda 


The Maeda Laboratory (Saitama University) hosted this years’ Kanto Area Spin Chemistry Meeting (KASC) on the 7thDecember at Saitama University. The meeting produced an abundance of excellent presentations and tutorials, including those given by three students and two professors of Saitama University. In addition to them, excellent and various presentations by spin chemists and related members from Niigata, Kanagawa, Kobe, and Tokyo.

KASC 2019 was honoured to welcome world-renowned professor Peter J Hore from the University of Oxford, who gave an exceptional tutorial on ‘How can weak magnetic fields affect chemical reactions?’. Prof Maeda and Dr Antill also enjoyed the stimulating discussions with and advice from Prof Hore and look forward to such future happenings.

During the evening of the meeting all attendees took pleasure in socialising over food and drink.
