Polymerized Pro‐Estrogen Microneedles via Two Photon Polymerization

open access: yesMacromolecular Rapid Communications, EarlyView.
Acrylic pro‐drugs of 17β‐estradiol were subjected to spatially controlled two‐photon polymerization to create bespoke microneedle geometries with potential biomedical applications for long‐term transdermal hormone delivery. ABSTRACT Two‐photon polymerization (TPP) is a powerful technique to create microscale structures with high precision, offering ...

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

open access: yesMacromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Investigation on Impact Behavior of Thermoplastic Composites: A Ply‐Level Numerical Methodology for Impact‐Resistance Design

open access: yesPolymer Composites, EarlyView.
Experimental and numerical investigation on impact‐tolerance efficient evaluation of soft TPU composites. ABSTRACT This study combines experimental characterization and numerical modeling to investigate the impact behavior of aramid fiber–reinforced composites incorporating a thermoplastic polyurethane (TPU) matrix. Low‐velocity impact (LVI) tests were

Molar incisor hypomineralisation: current knowledge and practice

open access: yesInternational Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...
