From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries
Advanced Energy Materials, EarlyView.This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Cost‐Benefit Analysis of the European Union Carbon Border Adjustment Mechanism in Fertilizer Trade
Agribusiness, EarlyView.ABSTRACT The carbon border adjustment mechanism (CBAM), launching 2026, will charge EU importers for embedded carbon emissions, aiming to reduce emissions but raising import costs. Shifts in demand following implementation may reduce carbon emissions, but importers will bear the cost of increased prices.

ESSENTIAL OILS OF TASMANIAN GROWN HOPS* [PDF]
Journal of the Institute of Brewing, 1982 The hop varieties Northern Brewer, Brewers' Gold, Bullion, Cluster, Pride of Ringwood and the new variety ‘B23’ were grown in Tasmania and their essential oils analysed, primarily by combined gas chromatography/mass spectrometry. The results for those varieties previously studied were similar to the published reports, while Pride of Ringwood and B23 ...

The Elusive [B(ReO4)4]− Anion in the Non‐Centrosymmetric Crystal Structure of K[B(ReO4)4]
Angewandte Chemie International Edition, EarlyView.Colorless crystals of K[B(ReO4)4] have been obtained from the reaction of KReO4 with B2O3 in a melt of Re2O7. According to single‐crystal structure analysis the compound has an anion which is built up by four (ReO4)‐tetrahedra coordinated to a central boron atom. Furthermore, the compound has been investigated by Raman spectroscopy and DFT calculations
