Low‐Temperature Depolymerization of Polymethacrylamides
Angewandte Chemie International EditionAbstract The depolymerization of polymers synthesized by reversible deactivation radical polymerization (RDRP) has recently garnered significant attention due to its potential for recovering monomers at low temperatures. However, current reports focus solely on polymethacrylates, significantly limiting applications, scope, and ...

Advanced Science, EarlyView.An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Advanced Science, EarlyView.Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

Simple Growth Models of Rigid Multifilament Biopolymers
, 2004 The growth dynamics of rigid biopolymers, consisting of $N$ parallel protofilaments, is investigated theoretically using simple approximate models. In our approach, the structure of a polymer's growing end and lateral interactions between protofilaments ...

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor
Angewandte Chemie, EarlyView.Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

On the Depolymerization of Polycapramide
Kobunshi Kagaku, 1961 アルカリ系触媒によるポリカプラミドの解重合について検討した。反応は約250℃ ですみやかに行なわれるが同時に多くの塩基性不純物を副生しその精製に手数がいるので工業的には問題がある。低温度の解重合においては反応系の減圧度がラクタムの留出速度に影響する。重合, 解重合反応速度と系内におけるe-カプロラクタムの溶解量に関係がある。N-アルカリ金属化したアミドはアニオンを媒介として他のアミドと容易にアミド交換反応を行ない重合, 解重合反応が行なわれる。
