Asymmetric Radical Polymerization.
Kobunshi, 1999 ラジカル重合による光学活性ポリマーの合成はポリマー鎖の高度な立対制御を必要とし,イオン重合や配位重合とは異なる重合設計が要求される.ここでは不斉ラジカル重合に関して不斉合成重合法,ポリマー鎖中のモノマー単位連鎖を非対称にする方法,ポリマーのらせん構造を一方向にする方法など,最近の光学活性ポリマーの合成例について概説する.

Challenges during Flash Lamp Annealing of Aerosol‐Deposited Barium Titanate Films
Advanced Engineering Materials, EarlyView.Aerosol deposition is used to rapidly deposit barium titanate films with thicknesses ranging from 2 to 16 μm at room temperature, eliminating the need for further densification. However, to recover the electromechanical properties, annealing is required, which limits the usage of temperature‐sensitive substrates.

Advanced Engineering Materials, EarlyView.Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Oil and fat absorbing polymers [PDF]
, 1977 A method is described for forming a solid network polymer having a minimal amount of crosslinking for use in absorbing fats and oils. The polymer remains solid at a swelling ratio in oil or fat of at least ten and provides an oil absorption greater than ...
