Enhanced removal of Cr (VI) in constructed wetland with Fe-Ni-LDH-modified crayfish shell biochar: Performance, removal pathways and synergy mechanisms of substrate-microorganism.

In this study, Fe-Ni-layered double hydroxide modified crayfish shell biochar substrate (Fe-Ni-LDH@CSBC) was successfully prepared and introduced into constructed wetland (CW) to research the Cr(VI) removal mechanism through substrate adsorption and microbial action. Adsorption experiments demonstrated the equilibrium adsorption capacities of Fe-Ni-LDH@CSBC for Cr(VI) could reach 1058.48 (C=10 mg/L) and 1394.

Co-Immobilization of Alcalase/Dispase for Production of Selenium-Enriched Peptide from .

Enzymatically derived selenium-enriched peptides from (CV) can serve as valuable selenium supplements. However, the industrial application of free enzyme is impeded by its limited stability and reusability. Herein, this study explores the application of co-immobilized enzymes (Alcalase and Dispase) on amino resin for hydrolyzing CV proteins to produce selenium-enriched peptides.

Application of Graphite Electrode Plasma Heating Technology in Continuous Casting.

In this study, the industrial, experimental effect of a plasma heating system in the form of graphite electrode in the tundish of double-strand slab caster was evaluated for the first time. The system uses three graphite electrodes, two of which are cathodes and one of which is an anode, to form a conductive loop through molten steel in the tundish. The system is built on an old two-strand slab caster and is installed on the premise that the original ladle tundish equipment remains unchanged.

Efficacy and safety of pioglitazone for treatment of plaque psoriasis: a systematic review and meta-analysis of randomized controlled trials.

A growing number of studies have shown that thiazolidinediones (TZD) can be antipsoriatic. Pioglitazone is a representative of the class of antidiabetic drugs known as TZD. TZD can activate nuclear peroxisome proliferator-activated receptors (PPAR)-c.

Effects on Surface and Physicochemical Properties of Dielectric Barrier Discharge Plasma-Treated Whey Protein Concentrate/Wheat Cross-Linked Starch Composite Film.

Dielectric barrier discharge (DBD) plasma is a new type of polymer surface modification technology. This study is mainly about the changes in film surface structure and physicochemical properties of whey protein concentrate (WPC)/wheat cross-linked starch (WCS) composite films after DBD plasma treatment with different plasma parameters. The results show that the proper plasma treatment parameters (400 W to 60 s) can increase the surface roughness, tensile strength, barrier properties, and thermal stability of the edible film and decrease elongation at break and the water contact angle.

Acetylated Distarch Phosphate/Chitosan Films Reinforced with Sodium Laurate-Modified Nano-TiO : Effects of Sodium Laurate Concentration.

Nano-titanium dioxide (TiO ) was modified with the surfactant sodium laurate (SL) via ultrasonic microwave-assisted technology to improve the dispersion of TiO in polymer matrices. As revealed by Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy analyses, SL was well adsorbed onto the TiO surface through chemical bonding, resulting in SL-modified TiO (TiO -SLx). The hydrophobicity and dispersibility of TiO -SLx increased significantly compared to unmodified nano-TiO .
