Aero-DETR: a frequency-adaptive sparse-interaction network for UAV-assisted aircraft surface defect detection

Abstract Aircraft surface defect inspection is critical for aviation safety but remains challenging because defects in unmanned aerial vehicle (UAV) imagery are often small, low-contrast, and multi-scale. We construct the aircraft UAV defect inspection dataset (AUDID), containing...

Towards low-carbon deep soil mixing: a complementary review of supplementary cementitious and alkali-activated binders

Abstract Deep soil mixing (DSM) is a proven in situ ground improvement technique conventionally employing cement/lime as hydraulic binders. Escalating concerns regarding greenhouse gas emissions and chemical durability of these materials have prompted the exploration of sustainab...

One‐Pot Direct Recycling of Spent LiCoO 2 via Synergistic Binder Defluorination and Phase Reconstruction

ABSTRACT Direct recycling of spent lithium‐ion battery cathodes is hindered by two interdependent challenges: persistent polyvinylidene fluoride (PVDF) binder residues that block particle surfaces and incomplete structural repair of degraded layered phases. Here, we report a one‐...
