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.

Fatigue Properties of Calcium Composite Free-Machining Steels
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 1973 S48Cをベースとして,これにCa, PbおよびSの快削成分を2種または3種複合添加した快削鋼について,この鋼を一体鍛造クランクシャフトに使用する場合に,要求される各種の強度特性が基本鋼に対して,どの程度の水準にあるかを試験した。また,複合快削鋼製クランクシャフトの曲げ疲労試験を行ない,丸棒試験片による結果と比較した。その結果Ca, Pb, Sを複合添加した快削鋼の疲労強度は基本鋼に劣るが,その差は大きくなく設計技術,製造技術によって充分にカバーしうることが明らかとなった。Ca-Pb-S鋼は,すぐれた被削性を有しており強度が多少基本鋼より劣る点をカバーできればクランクシャフトの用材として実用化しても何ら問題はない。

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...
