Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Ring-Opening Polymerization of Tetrahydrofuran
Kobunshi Kagaku, 1970 テトラヒドロララン (THF) のカチオン開環重合の開始反応機構および素反応速度に関する研究を行なった。開始反応におけるエピクロルヒドリン (ECH) の挙動を重合初期生成物の検討によって明らかにした。重合初期に系をCH3ONaで処理したときの生成物をガスクロマトグラフで分析した結果, ECHの開環によって重合が開始され, 環状トリアルキルオキソニウムイオンL-O-CH- (CH2Cl) CH2+Oが生成することがわかった。この結果は, 筆者が先に提案したプロモーターの概念を支持するものである。つぎに重合の素反応における触媒種の影響を速度論的に検討した。各種開始剤による重合の成長活性種濃度 [P*] を測定し, 成長反応速度定数kpを求めた。リビング重合とならない系においても ...
