Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Critical Review on the Molecular Behavior of Surfactants at the Oil–Water Interface During Oil Displacement

Energy Science &Engineering, EarlyView.
This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.
