Bioactive Glass Microscaffolds Fabricated by Two‐Photon Lithography

open access: yesAdvanced Materials, EarlyView.
Microstructuring of bioactive glasses offers great potential to influence cell behavior for bone tissue engineering. By utilizing two‐photon lithography of a nanocomposite and thermal post‐processing, single‐micron features and complex structures are achieved.

Tunable Preparation of β‐Substituted Alkenoate Esters via Radical Alkenylation of C(sp3)–H Bonds with Allenoates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Electro‐Thermal Response of Thin Film Heaters Based on Embedded Periodic Metallic Mesh

open access: yesAdvanced Theory and Simulations, EarlyView.
“This study systematically investigates the effect of periodic metallic mesh topology on electrical and electro‐thermal behaviours of thin thermal heaters. The derived closed‐form expressions capture the dependence of sheet resistance on design parameters, providing a crucial tool for rapidly exploring a vast design space and accelerating design and ...
