Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

open access: yesAdvanced Materials, Volume 38, Issue 44, 7 August 2026.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Ag‐Assisted Interfacial Assembly of 2D/0D/2D Ti3C2Tx/Ag@g‐C3N4 Films With Synergistic Electromagnetic Interference Shielding and Thermal Management

open access: yesEcoMat, Volume 8, Issue 8, August 2026.
Lightweight 2D/0D/2D Ti3C2Tx/Ag@g‐C3N4 composite films are fabricated via an Ag‐assisted self‐assembly strategy to construct abundant heterogeneous interfaces. Benefiting from a continuous conductive network and Ag‐bridged interfaces, the films exhibit high EMI shielding effectiveness, low infrared emissivity, and rapid low‐voltage Joule heating.

Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

open access: yesEnergy Science &Engineering, Volume 14, Issue 8, Page 3828-3847, August 2026.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.
