Simulation of sandstone degradation using large-scale slake durability index testing device [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2012 Large-scale slake durability index tests have been performed on Khok Kruat (KK), Phu Kradung (PK) and Phra Wihan(PW) sandstone. A rotating drum with a diameter of 64 cm and length of 40 cm was fabricated to accommodate ten rockfragments with a nominal ...

Advanced Science, EarlyView.Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...

Advanced Science, EarlyView.A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Rare earth elements in gneiss regoliths in southern Minas Gerais, Brazil
Scientia Agricola: Regolith characterization in its entirety is particularly difficult in gneissic regoliths due to the heterogeneity of their rock structure. Rare earth elements (REE) are a useful tool in helping understand the evolution of regoliths. This study relates
