Affordable Biogenic Anti‐Icing Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
The article explores affordable biogenic coatings that prevent icing by combining coconut shell charcoal with natural hydrophobic agents such as beeswax. It shows how particle size and surface treatment influence water repellence, heat absorption, and self‐cleaning ability.

Perovskite Quantum Dots for Improvement in Efficiency of Perovskite Solar Cells: Recent Advances and Prospects

open access: yesAdvanced Materials Interfaces, EarlyView.
Quantum dots (QDs) boost perovskite solar cells (PSCs) performance/stability via tunable bandgap, energy alignment, and interfacial engineering. This review covers three frontiers: 1. interfacial defect passivation by Ligand‐engineered QDs in PSCs. 2. QDs multifunctional interlayers via bandgap/energy alignment. 3. QDs in tandem cells.

Deep Seek to the Excited States: A Thermally‐Activated Jahn–Teller Effect Achieves Superior Sensitivity for Thermometry at Cryogenic Temperature

open access: yesAdvanced Optical Materials, EarlyView.
A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.
