Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...

Polyethylene Terephthalate: Sax Responds

Environmental Health Perspectives, 2010
In his letter Vasami reminds readers that phthalates are not used in the manufacture of PET. Indeed, I emphasized precisely this point in my commentary (Sax 2010), for example, when I stated that “phthalates are not used as substrates or precursors in the manufacture of PET.” Vasami also asserts that “it is not chemically plausible for PET to produce ...

Polyethylene Isophthalate Terephthalate Copolymer

Kobunshi Kagaku, 1957
テレフタル酸ジメチル, イソフタル酸ジメチルおよびエチレングリコールよりPbOを触媒として溶融重合によって, 種々の組成のポリエチレンイソフタレートテレフタレート共重合体を合成した。これら共重合体はいずれも良好な曳糸性を有し, 粘度数が大きいものでは冷延伸も容易である。エチレンイソフタレートが20%以下のものは結晶性を有し, 加熱や延伸などによってこれらを結晶化させることが可能である。延伸熱処理糸のX線図によれば, 結晶部分はエチレンテレフタレートのみよりなり, エチレンイソフタレートは非晶部分に存在するものと考えられる。

3D‐Printed Arch‐Structured Tribolayer with Conducting Polymer Coating for Enhanced Triboelectric Energy Harvesting

Advanced Materials Interfaces, EarlyView.
PEDOT:PSS‐coated 3DP microstructures are introduced to realize TENGs with enhanced mechanical compliance and high electrical performance. Among the investigated geometries, arch‐shaped microstructures exhibit superior fatigue resistance due to their spring‐like behavior, enabling efficient stress distribution, stable contact evolution, and sustained ...
