Clinical Significance of Congo Red Test

open access: yesThe Tohoku Journal of Experimental Medicine, 1976
Clinical significance of Congo red test was studied, especially on its relation to the liver function and amyloidosis. No significant relationship was observed between Congo red test and Indocyanin green test in cases of various liver diseases except liver cirrhosis. Histological studies also revealed that there were no pathologic features specifically

Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Organometallic Precursor‐Induced Gradient Architecture on Multilayer Nanoporous Graphene Membranes for Precise Organic Solvent Nanofiltration

open access: yesAdvanced Functional Materials, EarlyView.
Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.
