Evolutionary trajectories of multiple defense traits across phylogenetic and geographic scales in Vitis

open access: yesEcography, EarlyView.
The processes driving defense trait correlations may vary within and between species based on ecological or environmental contexts. However, most studies of plant defense theory fail to address this potential for shifts in trait correlations across scales.

Hierarchically Porous Heteroatom‐co‐Doped Carbons for Enhanced Carbon Dioxide Capture

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Polythiophene‐derived N,S‐co‐doped carbons with tailored surface functionalities exhibit enhanced CO₂ adsorption. The efficiency of carbon dioxide (CO2) adsorption in carbonaceous materials is primarily influenced by their microporosity and thermodynamic affinity for CO2.

Evaluation and auger analysis of a zinc-dialkyl-dithiophosphate antiwear additive in several diester lubricants [PDF]

open access: yes
The wear of pure iron in sliding contact with hardened M-2 tool steel was measured for a series of synthetic diester fluids, both with and without a zinc dialkyl dithiophosphate (ZDP) antiwear additive, as test lubricants.
