Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Balancing the spatially separated p‐ and n‐type transport pathways in heterojunction‐bilayer OTFTs enables symmetric inverter switching (VM ≈ 0.5VDD), whereas discrete integration of unipolar OTFTs gives polarity‐dependent and resistive responses. ABSTRACT High inverter performance in ambipolar organic electronics requires balanced channel strengths ...

The synthesis and characterisation of some ortho-substituted phenoxyalkanoic acids and their derivatives [PDF]
The synthesis of 2-phenoxyalkanoic acids (ethanoic, propanoic, butanoic) was realised by the reaction of ortho-hydroxybenzamide respectively N-phenyl-o-hydroxybenzamide with a-halogenated acids in aqueous sodium hydroxide solution.

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐

This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

O conceito de "campo" em sala de aula: uma abordagem histórico-conceitual
O conceito de campo é uma das idéias fundamentais da física e pode motivar um rico debate em sala de aula sobre as noções básicas desta ciência. Apesar de sua importância, quando o mesmo é apresentado em sala de aula geralmente somente seus aspectos ...
