Application of High‐Strength Lightweight Concrete in Gob‐Side Entry Retaining in Inclined Coal Seam [PDF]
Advances in Materials Science and Engineering, 2020 Gob‐side entry retaining (GSER) is a popular no‐pillar mining technology that can increase coal recovery rate. We propose the application of high‐strength lightweight (HSLW) concrete to construct the gob‐side support body (GSSB) in NO. 411 inclined working face of Jingang Coal Mine. Firstly, the mechanical model of retained roadway was established, and

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
