Development of Injectable Thermosensitive Chitosan-Based Hydrogels for Cell Encapsulation

open access: yesApplied Sciences, 2020
The three-dimensional complexity of the native extracellular matrix (ECM) suggests switching from 2D to 3D culture systems for providing the cells with an architecture more similar to the physiological environment. Reproducing the three-dimensionality in

Relationship between swelling ratio and liquefaction yield of coals.

open access: yesJournal of the Fuel Society of Japan, 1987
In order to clarify swelling effect on liquefaction of coals, swelling ratios, liquefaction yield, heats of wetting, and water contents of coals with various carbon contents have been studied in methanol, tetralin, and mixtures of them.The swelling ratios of Yallourn coal in all solvents we used were increased up to 60 minutes, and then became a ...
