The potential of paper mill sludge for wood–plastic

For the WPC with 30% CTMP, when the SS ratio was increased from 1:9 to 3:7, the flexural strength dropped from 41 to 31 MPa. Thus, the adhesive properties of the SS did not appear to contribute to the WPC mechanical strength. Further surface chemistry analysis are needed to identify the adhesion mechanisms of the PS and SS in the WPC.

Acetylated tubulin is essential for touch sensation in mice

At its most fundamental level, touch sensation requires the translation of mechanical energy into mechanosensitive ion channel opening, thereby generating electro-chemical signals. Our understanding of this process, especially how the cytoskeleton influences it, remains unknown. Here we demonstrate that mice lacking the α-tubulin acetyltransferase Atat1 in sensory neurons display profound

A higher impact strength enhanced the ability of the material to absorb mechanical energy during deformation and fracture under impact loading. In the case of the PP-KBF-S, the probable explanation for this was that the energy absorbed by the matrix was transferred to the silica particles, which increased the impact strength (Bajuri et al. 2016).
