Comparative investigation on the adsorption behavior of bromate in aqueous solutions using Zn/Ni/Al-LDH and Ni/Al-LDH: optimization, equilibrium analysis, and mechanistic insights.

Unlabelled: The presence of bromate in water poses a significant health risk. In order to effectively eliminate bromate from water, this study synthesized a series of ternary Zn-Ni-Al layered double hydroxides with varying Zn/Ni/Al atomic ratios using a co-precipitation method. The adsorbents were characterized using various techniques including XRD, Fourier transform infrared spectroscopy, and N adsorption-desorption isotherms.

Novel CuMgAlTi-LDH Photocatalyst for Efficient Degradation of Microplastics under Visible Light Irradiation.

Microplastics (MPs) in the water system could easily enter the human body and pose a potential threat, so finding a green and effective solution remains a great challenge. At present, the advanced oxidation technology represented by photocatalysis has been proven to be effective in the removal of organic pollutants, making it a feasible method to solve the problem of MP pollution. In this study, the photocatalytic degradation of typical MP polystyrene (PS) and polyethylene (PE) by a new quaternary layered double hydroxide composite photomaterial CuMgAlTi-R400 was tested under visible light irradiation.

Wafer-scale nanostructured black silicon with morphology engineering advanced Sn-assisted dry etching for sensing and solar cell applications.

Black-Si (b-Si) providing broadband light antireflection has become a versatile substrate for photodetectors, photo-electric catalysis, sensors, and photovoltaic devices. However, the conventional fabrication methods suffer from single morphology, low yield, or frangibility. In this work, we present a high-yield CMOS-compatible technique to produce 6-inch wafer-scale b-Si with diverse random nanostructures.

In Situ Chemical Modification with Zwitterionic Copolymers of Nanofiltration Membranes: Cure for the Trade-Off between Filtration and Antifouling Performance.

Breaking the trade-off between filtration performance and antifouling property is critical to enabling a thin-film nanocomposite (TFC) nanofiltration (NF) membrane for a wide range of feed streams. We proposed a novel design route for TFC NF membranes by grafting well-defined zwitterionic copolymers of [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA) and 2-aminoethyl methacrylate hydrochloride (AEMA) on the polyamide surfaces via an in situ surface chemical modification process. The successful grafting of a zwitterionic copolymer imparted the modified NF membranes with better surface hydrophilicity, a larger actual surface area (i.

Bioremediation of oil contaminated soil using agricultural wastes via microbial consortium.

Agricultural wastes, such as wheat bran and swine wastewater, were used for bioremediation of oil-contaminated soil. Two optimised strains that could degrade oil efficiently were selected. The result showed that the best ratio of strain A to strain B was 7:3.

Economical production of vitamin K using crude glycerol from the by-product of biodiesel.

Industrial waste, such as crude glycerol, was used for vitamin K by B. subtilis Z-15. Crude glycerol could be used instead of pure glycerin for vitamin K production.

Biosorption of Cr(VI) by immobilized waste biomass from polyglutamic acid production.

Waste biomass from γ-polyglutamic acid production was used as an adsorbent to remove Cr(VI) from wastewater. Waste biomass was entrapped in sodium alginate to enhance performance. Orthogonal array design was used to optimize biosorption of Cr(VI) by immobilized waste biomass.

Mycelial pellets formed by Aspergillus niger A-15 were used to immobilize the ethanol producing yeast Saccharomyces cerevisiae C-15. The operation parameters, such as agitation speed, temperature and mixed proportion of strains were studied. The optimal adsorption 66.

Efficient lead ion removal from water by a novel chitosan gel-based sorbent modified with glutamic acid ionic liquid.

Three novel and highly effective AAIL-modified Chitosan (CS) adsorbents are presented. These three new CS-gels were prepared by an innovative synthetic method that uses amino acid ionic liquids (AA-ILs) to cross-link CS with, separately, glutamic acid, aspartic acid and alanine to give novel adsorbents Glu-AA-IL-CS (1), Asp-AA-IL-CS (2) and Ala-AA-IL-CS (3) respectively. The effectively incarcerating host-structures (1) - (3) were characterized by a whole range of techniques including FT-IR, SEM, EDS and XRD.

The specific surface area and aperture of the prepared SA-CMC gel beads were tested. The SA-CMC structure was characterized and analyzed via infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy.

A water-soluble fluorescent pH probe based on perylene dyes and its application to cell imaging.

A fluorescent pH probe, N,N'-bi( l-phenylalanine amine)-perylene-3,4;9,10-dicarboxylic diimide (PDCDA) was synthesized and used for pH sensing in living cells. A significant fluorescence intensity change was observed over a pH range from 7.0 to 4.

Iron(II)-dependent dioxygenase and N-formylamide deformylase catalyze the reactions from 5-hydroxy-2-pyridone to maleamate.

5-Hydroxy-2-pyridone (2,5-DHP) is a central metabolic intermediate in catabolism of many pyridine derivatives, and has been suggested as a potential carcinogen. 2,5-DHP is frequently transformed to N-formylmaleamic acid (NFM) by a 2,5-DHP dioxygenase. Three hypotheses were formerly discussed for conversion of 2,5-DHP to maleamate.
