Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

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,

Crack Initiation Characteristics of Gas-Containing Coal under Gas Pressures

Geofluids, 2019
In deep coal mines, coal before the working face is subjected to coupled high mining-induced stress and gas pressure. Such condition may facilitate crack formation and propagation in the coal seam, leading to serious coal and gas disasters. In this study,

Uniaxial and Plane-Strain Compressive Strength of Model Ice [PDF]

Annals of Glaciology, 1983
In order to interpret reliably the results of model tests which involve compressive (crushing) failures, the compressive strength of the model ice must be known. In this paper, the uniaxial and plane-strain compressive strengths of carbamide (urea) model ice are documented for scale factors of 40>λ>5.
