Exploring 3D Printing and Electrospinning Technologies for Advanced Porous Membrane Fabrication: A Review

open access: yesAdvanced Materials Technologies, EarlyView.
This paper contrasts electrospinning and 3D printing for porous membrane fabrication, evaluating their evolution, cost, resolution, mechanical traits, and scalability. While 3D printing excels in material diversity and industrial adaptability, electrospinning achieves finer resolution and thermal resilience.

Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing

open access: yesAdvanced Materials Technologies, EarlyView.
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.

Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

open access: yesAdvanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...

Mg(SPh)2 as a Catalyst for Efficient Photocatalytic Alkylation Reactions of Active Methylene Compounds with Nonactivated Alkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Mg(SPh)2 has been found to be a highly active catalyst in photocatalytic alkylation reactions of active methylene compounds with nonactivated alkenes. The desired reactions proceeded smoothly to afford the corresponding alkylated products in high yields with low catalyst loadings (0.2–0.3 mol%). This protocol is applicable to a continuous‐flow
