Aero‐breakup of droplets: Recent progress and outlook

Droplet, EarlyView.
This work systematically reviews the recent progress of droplet aero‐breakup studies. The discussion covers the research history, theoretical framework, new breakup mode discoveries, influence of droplet fluid properties, scenarios of multi‐droplet and droplet cloud, and finally, an outlook for future explorations is presented.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Electron‐Rich Para‐Methylpyridine‐Functionalized TEMPO Empowers Long‐Lived Neutral Aqueous Organic Redox Flow Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Three methylpyridine‐functionalized TEMPOs were synthesized through an electron‐rich regulation strategy. The calculation of transition states supported the highest reaction efficiency of para‐MePy‐TEMPOs, which outperformed its analogues to have the best performance of AORFBs, opening a new avenue for exploring TEMPO‐based catholytes.

Optimal Lithium‐Ion Battery—Supercapacitor Energy Storage System Capacity for Off‐Grid Intermittent Renewable Energy Mini‐Grids

Energy Science &Engineering, EarlyView.
Deployment of an aging‐based controller during designing of optimal lithium‐ion battery—supercapacitor (LB‐Sc) hybrid energy storage system (HESS) capacity, in off‐grid IREMGs, improves performance of the LB and reduces its aging rate. Also, annualised cost of the LB‐Sc HESS improves by 33.15% in relation to optimal LB SESS.
