Additive Manufacturing of Alumina‐Reinforced Elastomers

Advanced Engineering Materials, EarlyView.
Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

On the Recycle of Waste Plastics Materials

Kobunshi, 1974
都市生活から排出される一般廃棄物の処理問題が深刻化するにつれて, その中に混入する廃プラスチックの回収,処理,有効利用に対する要望が高まってきた.現在プラスチック業界としても回収の促進,有効利用の技術開発が進められているが,これらの対策だけで清掃責任をもつ地方自治体の要求に答えることができるであろうか.今後の廃プラスチックの問題を考えるにあたっては資源有限性の観点と,プラスチック製品のライフサイクルに基づく廃棄率の時間おくれなどの要因を考えに入れなければならない.そのためには生産から廃棄に至るまでのトータルなプロセスを考えに入れた上で,発想を新たにして問題に取り組む必要がある.今後の廃プラスチックの回収システムをデザインする上で工夫を要するいくつかの点を指摘する.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
