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.

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Neutrino Emissivity in the Quark-Hadron Mixed Phase
Universe, 2018 In this work we investigate the effect a crystalline quark–hadron mixed phase can have on the neutrino emissivity from the cores of neutron stars. To this end we use relativistic mean-field equations of state to model hadronic matter and a nonlocal

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer
Advanced Functional Materials, EarlyView.Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Fabrication of poly(vinylidene fluoride) film and application to printing technology
Mechanical Engineering Journal, 2016 Poly(vinylidene fluoride) (PVDF) has four crystalline structures (α, β, γ and δ phase structures) in solid state. Only α-phase structure shows no crystal dipole, but this phase structure is converted easily into other phase structures according to some ...

Crystalline Structures and Non-crystalline States of Polymers
Kobunshi, 1971 高分子とは何かを構造の面から浮き彫りにするため,低分子との比較から出発し,プラスチック,フィルム,繊維などで強さを表わす高分子の特長が,ラメラ晶,球晶間のtie-linkによる網目構造的なものに関係していることを強調した。他方,無定形ガラス状態にある高分子について,ランダムコイルか特殊な形態をとるのかという問題を提起した。次に高分子が結晶を形成する因子について説明し,結晶弾性率を解説した。結晶,非晶両領域の共存する高次構造を説明する基礎として,希薄溶液から単結晶の析出する機構を考察し,次に溶融状態からの球晶の生成とその高次構造について述べた。ラメラ晶の規則的集合からなる球晶の変形を基本的な過程に分離して説明し,最後に配向結晶化による配向物の構造の特長を指摘し, 強度を支配するtie-link ...

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
