PMID: 33233413
Materials (Basel). 2020 Nov 21;13(22). doi: 10.3390/ma13225270.

Hydrogels, three-dimensional (3D) polymer networks, present unique properties, like biocompatibility, biodegradability, tunable mechanical properties, sensitivity to various stimuli, the capacity to encapsulate different therapeutic agents, and the ability of controlled release of the drugs. All these characteristics make hydrogels...

Effects of nitrogen fertilization and bioenergy crop species on central tendency and spatial heterogeneity of soil glycosidase activities.

Scientific reports

Yuan M, Duan J, Li J, Jian S, Gamage L, Dzantor KE, Hui D, Fay PA.
PMID: 33184435
Sci Rep. 2020 Nov 12;10(1):19681. doi: 10.1038/s41598-020-76837-1.

Extracellular glycosidases in soil, produced by microorganisms, act as major agents for decomposing labile soil organic carbon (e.g., cellulose). Soil extracellular glycosidases are significantly affected by nitrogen (N) fertilization but fertilization effects on spatial distributions of soil glycosidases have...
