Nitrogen use efficiency in cereals production under Mediterranean conditions [PDF]

open access: yes, 2014
Nitrogen use efficiency (NUE) for cereal production in Mediterranean regions is generally low due to N losses over winter and difficulties in calculating the optimum N level for a particular season, given that it depends on the existing rainfall pattern.

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition
