研究室旅行 & 9/12〜14 の輪読

9/15（金）には生物制御化学研究室と化学生態学研究室合同で稲敷市のこもれび森のイバライド（旧ポティロンの森）へ日帰り旅行に行きました．イバライドでは芝滑り，キャンドル作り，バーベキュー，動物への餌やりやふれあい，ゴーカート，ロングジップスライドなどで一日遊びました．

停電，8/28 〜 9/1 の輪読

9/2（土）は年に一度の電気設備点検のための停電がありました．停電の時には常時稼働している NMR や質量分析計などを停止しなければいけません．今回は停止ついでに LC/MS/MS のメンテナンスも実施しました．停電後の再起動も特に問題なく，各機器とも週明けから順調に使えているようです．
