In vitro immunotoxicity of untreated and treated urban wastewaters using various treatment processes to rainbow trout leucocytes.
TL;DR: Examining the immunotoxicity of urban wastewaters before and after 6 treatment processes from 12 cities toward trout leucocytes revealed that municipal effluents have the potential to alter the immune system in fish and more research will be needed to improve the treatments of wastewater to better protect the quality of the aquatic environment.

Facile Fabrication of 3D Graphene⁻Silica Hydrogel Composite for Enhanced Removal of Mercury Ions.
TL;DR: Mechanism study showed that the high adsorption ability was due to the formation of an N–Hg complex with multi-amino groups on the surface of polyethyleneimine-modified silica gel (SG-PEI) and the rapid diffusion of adsorbed ions attributed to the rGH network structure.

Stress-induced fragmentation of multiwall carbon nanotubes in a polymer matrix
TL;DR: In this article, the authors report the observation of single nanotube fragmentation, under tensile stresses, using nanotubes-containing thin polymeric films, and they estimate that the multi-wall multi-nanotube-matrix stress transfer efficiency is at least one order of magnitude larger than in conventional fiber-based composites.
