Kate visited Lille this week to perform some specific heat measurements with the kind help of Dr Angel Arevalo Lopez. It was great to see the Chemistry department there and to have the opportunity to give a seminar encompassing recently published work on oxalate materials, past work on barlowite and ongoing work on metal organic-framework materials. Kate also had the opportunity to explore the beautiful city of Lille and the Fête de la Musique which takes place there every year.
