A Review on Laser-Induced Graphene-Based Electrocatalysts for the Oxygen Reduction Reaction in Electrochemical Energy Storage and Conversion

Published on 2025-07-10 by Giulia Massaglia, Marzia Quaglio @MDPI

Abstract: The increasing demand for efficient and sustainable energy conversion technologies has driven extensive research into alternative electrocatalysts for the oxygen reduction reaction (ORR). Platinum-based catalysts, while highly efficient, suffer from high costs, scarcity, and long-term instability Laser-Induced Graphene (LIG) has recently attracted considerable interest as an effective metal-free electrocatalyst for oxygen reduction reaction (ORR), owing to its remarkable electrical conductivity,[...]

Our summary: A review on the synthesis, properties, and performance of Laser-Induced Graphene-based electrocatalysts for the oxygen reduction reaction. Discussion on heteroatom doping and functionalization techniques. Highlighting challenges and future perspectives for LIG-based ORR catalysts.

Composite rotator cuff patch and preparation method therefor

Patent published on the 2025-06-12 in WO under Ref WO2025118346 by GUANHAO BIOTECH CO LTD [CN] (Mo Ziru [cn])

Abstract: Disclosed in the present application are a composite rotator cuff patch and a preparation method therefor. The composite rotator cuff patch is divided into an electrospun layer and a collagen layer. An electrospun nanofiber membrane is coated with a layer of cross-linked collagen gel, and then composite freeze-drying is carried out to obtain the composite rotator cuff patch of the present application. The rotator cuff patch has good biocompatibility and proper tissue adhesion, does not require s[...]

Our summary: Composite rotator cuff patch with electrospun and collagen layers, prepared by composite freeze-drying for good biocompatibility and tissue adhesion, no sutures needed for fixation, degrades in vivo without postoperative removal.
