Mechanical, Thermal, and Shape Memory Properties of Three-Dimensional Printing Biomass Composites
This article studies studies the preparation of a series of heat-induced shape memory composites by the hot-melt extrusion and three-dimensional (3D) printing of thermoplastic polyurethane (TPU) using wood flour (WF) with different contents of EPDM-g-MAH.

Seasonal variations of biogeochemical matter export along the Langtang-Narayani river system in central Himalaya
Article describes study in which weathering and suspended matter fluxes of the Langtang Narayani river system in central Nepal Himalaya were investigated at 16 stations for one year, based on monthly water sampling in the lower reaches and bi-monthly in higher elevation areas, to determine temporal variations of weathering fluxes along an elevation profile between 169 and 3989 m asl.

Experimental and Computational Studies of the Kinetics of the Reaction of Hydrogen Atoms with Carbon Disulfide
Article discussing an investigation of the reaction of H + CS₂ products. The reaction was found to be pressure dependent and in the fall-off region or near the low pressure limit. Transition state theory yields an estimate for the high-pressure limit of addition over 290–300 K of 1.3 × 10−9 exp( −7.2 kJ mol −1 /RT) cm3 molecule −1 s −1. Uncertainties are discussed in the text.
