A Self‐Curling Si3N4‐Biofunctionalized Nerve Wrap for Suture‐Free Peripheral Nerve Repair with Multimodal Regenerative Bioregulation

Advanced Functional Materials, EarlyView.
Si3N4‐enhanced bioactive nanostructured adhesive wrap enables rapid conduit formation in wet environments, simplifying surgical procedures. Incorporated Si3N4 undergoes controlled hydrolysis within nanofibers, multi‐directionally modulating the peripheral nerve repair microenvironment for effective suture‐free repair.

AGN Dusty Tori as a Clumpy Two-Phase Medium: The 10 Micron Silicate Feature

, 2011
We investigated the emission of active galactic nuclei dusty tori in the infrared domain, with a focus on the 10 micron silicate feature. We modeled the dusty torus as a clumpy two-phase medium with high-density clumps and a low-density medium filling ...

Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

Advanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Enhanced silicate weathering is not limited by silicic acid saturation [PDF]

Proceedings of the National Academy of Sciences, 2011
Enhanced weathering of olivine as a means of sequestering carbon is investigated by Kohler et al. (1). Specifically, the study discusses the potential distribution of fine olivine powder, obtained from dunite mines, in the humid tropic regions of the Amazon and Congo River catchments. Olivine (forsterite) dissolution (Eq.
