Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Integrating ZnO/Ag2O@g‐C3N4‐Based Nanocomposites Into a Carrageenan Matrix to Efficiently Remove Heavy Metals From Water

Advanced Materials Interfaces, EarlyView.
ABSTRACT This research focused on characterizing graphitic carbon nitride (g‐C3N4) nanocomposites incorporated with ZnO and Ag2O nanoparticles, and carrageenan to remove heavy metals. The ZnO/Ag2O@ g‐C3N4 and ZnO/Ag2O/g‐C3N4@Carr nanocomposites demonstrated thermal stability of 97.40% (108.81°C) and 82.80% (188.99°C) for TGA.

Electron donors for biological sulfate reduction

Biotechnology Advances, 2007
Biological sulfate reduction is widely used for treating sulfate-containing wastewaters from industries such as mining, tannery, pulp and paper, and textiles. In biological reduction, sulfate is converted to hydrogen sulfide as the end product. The process is, therefore, ideally suited for treating metal-containing wastewater from which heavy metals ...

Sulfate reduction in Lake Agmon, Israel

The Science of The Total Environment, 2001
Lake Agmon, a newly reflooded water body in the southern part of the Hula valley is characterized by a clear phase period in winter with almost no blooms of phytoplankton. Dense macrobenthos and algal blooms form in the lake during summer and autumn. High primary production and chlorophyll-a concentrations were measured in April and during the summer ...

Aerobic Sulfate Reduction in Microbial Mats

Science, 1991
Measurements of bacterial sulfate reduction and dissolved oxygen (O 2 ) in hypersaline bacterial mats from Baja California, Mexico, revealed that sulfate reduction occurred consistently within the well-oxygenated photosynthetic zone of the mats.

Assimilatory Sulfate Reduction

1981
The roles of sulfur and nitrogen in cell nutrition show many similarities. Both must be reduced by living systems to form proteins and other macromolecules and both, therefore, appear among the macroelements required by plants and plant-like microorganisms.
