Extraction and Quantification of Hydrolyzable Tannins in Acorns from Different Species of Oak Trees (Quercus spp.) [PDF]

open access: yes, 2019
Do white-tailed deer (Odocoileus virginianus) prefer to eat certain types of acorns based on tannin content? Hydrolyzable tannins consist of gallate groups connected via ester linkages to a carbohydrate (D-glucose) The Prussian Blue method was used to ...

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...

Effects of litters with different concentrations of phenolics on the competition between Calluna vulgaris and Deschampsia flexuosa [PDF]

open access: yes
We hypothesized that the outcome of competition between ericaceous plants and grasses is strongly affected by the concentrations of phenolics in the litter that they produce.

Bistable Dual‐Responsive Azobenzene‐co‐PNIPAM Soft Microactuators via Two‐Photon Direct Laser Writing

open access: yesAdvanced Intelligent Systems, EarlyView.
This work shows the successful integration of intrinsic bistability into thermoresponsive soft microactuators, fabricated by two‐photon polymerization utilizing the (E)–(Z)‐isomerization of azobenzenes. The bistable behavior accounts for a reversible volume change of Azo_pNIPAM microactuators initiated by light irradiation, at constant ambient ...
