Contact allergy to (meth)acrylates in gel nail polish in a child: An emerging risk for children

, 2020
Acrylates and methacrylates are well-known contact sensitizers innon-occupational (dental or orthopedic prostheses, electrodes formedical devices, artificial nails) and occupational settings (dentists,dental technicians, nail artists).

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Synthesis, characterization and photoinduced curing of polysulfones with (meth)acrylate functionalities

Beilstein Journal of Organic Chemistry, 2010
The UV-curable telechelic polysulfones with (meth)acrylate functionalities were synthesized by condensation polymerization and subsequent esterification. The final polymers and intermediates at various stages were characterized by 1H NMR, FT-ATR, and GPC.

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Verfahren zur Synthese von Acryl- und Methacrylverhindungen durch Eliminierungs- und Austauschreaktionen in flüssiger Phase

CHIMIA, 1973
Synthesis of acryl- and methacryl derivatives via elimination and interchange reactions of suitable compounds are described. Decarboxylation of maleic monoesters in a pyridine base/basic copper salts pyrolysis bath at 210 °C leads to the corresponding

Molecularly Dissipative Liquid Crystal Elastomer Foams for Impact and Vibration Attenuation

Advanced Functional Materials, EarlyView.
Liquid crystal elastomer foams integrate cellular deformation with mesogen reorientation to create a dual‐scale energy dissipation mechanism. Progressive pore collapse absorbs mechanical loads, while stress‐induced mesogen reorientation provides additional damping, resulting in reduced impact transmission and broadband suppression of vibrational ...

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Preparation of 3-(9-Anthryl)acrylates and 9-Aroylethenylanthracenes as Pi-Extended Anthracenes and Their Diels–Alder Type Adducts with Electron-Poor Dienophiles

, 2017
(E)-3-(9-Anthryl)acrylates and (E)-9-aroylethenylanthracenes have been prepared by solventless Wittig olefination with conjugated phosphoranes. The (E)-3-(9-anthryl)acrylates were brominated to give (E)-3[10-{9-bromoanthryl}]acrylates, which could be ...
