A series of consecutively adjustable submerged vegetation nets were constructed in a polluted shallow river with a length of about 200 m and nearby the water resource protection area of Taihu Lake in East China, forming an aquatic vegetation consisted of submerged plant species Cabomba caroliniana, Vallisneria natans, Elodea nuttallii, Hydrilla verticillata, and Potamogeton crispus. The water quality indices including total nitrogen (TN), ammonium nitrogen (NH4(+)-N), nitrite nitrogen (NO2(-)-N), nitrate nitrogen (NO3(-)-N), total phosphorus (TP), and phosphate (PO4(3-)-P) were monitored, and the bioremediation effect of the vegetation nets was evaluated. After setting up the vegetation nets, the Secchi depth (SD) of the river changed from 0.5 m to 1.7-1.8 m, and the TN and TP concentrations 15 and 20 days after the nets constructed decreased by 35.6% and 66.3%, and 29.4% and 63.2%, respectively. After five months, the concentrations of NH4(+)-N, NO2(-)-N, NO3(-)-N, TN, TP, and PO4(3-)-P decreased by 92.4%, 76.8%, 72.7%, 73.9%, 90.5%, and 92.0%, respectively. This study showed that consecutively adjustable submerged vegetation net could be a potential approach for treating polluted river waters, particularly for the bioremediation of polluted small landscape shallow water bodies.

Sodium dodecyl sulfate capillary gel electrophoresis (SDS-CGE) is a frequently used analytical technique in size-based separation of proteins, playing a vital role in the biopharmaceutical industry for the analysis and characterization of therapeutic proteins, employing both UV and fluorescent detection. Understanding the effect of the operational parameters using easily applicable in migratio fluorescent labeling is increasingly critical, especially because multicapillary electrophoresis systems with fluorescent detection have recently gained prominence in high-throughput biopolymer analysis. In this study, the effects of the three most important user-adjustable operational parameters (temperature, gel concentration, and electric field strength) were investigated on the electrophoretic mobility and resolution of SDS-protein complexes in the presence of propidium iodide in the gel-buffer system.

Hydrogen sulfide (HS) is a major air pollutant posing a serious threat to both the environment and public health. In this study, a novel nitrogen-rich biocarbon that effectively removes HS was produced from a mixture of sewage sludge and pine sawdust using melamine as nitrogen source. Compared with pristine biocarbons, nitrogen (N)-doped biocarbons possessed an adjustable porosity, e.

Metal-organic frameworks (MOFs) have gained considerable interest as crystalline porous materials with notable characteristics, such as high surface area and excellent electrochemical performance, particularly in supercapacitor applications. The combination of MOFs with various nanocarbon materials further enhances their performance. This study investigated the combination of zirconium-based MOFs (Zr-MOFs) with graphene oxide nanoribbons (GONRs), zipped carbon nanotubes, and functionalized carbon nanotubes (FCNTs) to fabricate composites with elevated electrical conductivity, adjustable surface area, chemical robustness, mechanical strength, and customizable attributes for specific applications.
