Bidirectional Disulfide Metathesis Enables Recycling of High‐Performance Thermoset Networks
Advanced Science, EarlyView.A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

Advanced Science, EarlyView.A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Advanced Science, EarlyView.An artificial bifunctional N‐deacetylase/N‐sulfotransferase was engineered in Escherichia coli by combining screened N‐deacetylases with an NST domain. The integrated engineering strategy improved enzyme performance. The optimized enzyme efficiently converted heparosan into N‐sulfated heparosan, addressing a key bottleneck in microbial heparin ...

Advanced Science, EarlyView.Single‐cell mechanomics demonstrates that pharmacological perturbation changes cytoskeletal and cortical structure, suppressing cancer cell invasiveness. By integrating atomic force microscopy (AFM)‐based cortical measurements with stimulated emission depletion (STED)‐resolved adhesion and cytoskeletal organization, this approach identifies nanoscale ...

Advanced Science, EarlyView.Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

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。
