Fe3O4 nanoparticles were prepared by a co-precipitation method with the assistance of ultrasound irradiation, and then coated with silica generated by hydrolysis and condensation of tetraethoxysilane. The silica-coated Fe3O4 nanoparticles were further modified with 3-aminopropyltriethoxysilane, resulting in anchoring of primary amine groups on the surface of the particles. Horseradish peroxidas...

The potential maternal, embryotoxic, and teratogenic parameters of 2,4-dichlorophenol (2,4-DCP) were evaluated in Fischer 344 rats following oral administration in corn oil on Days 6 through 15 of gestation. Dose levels were 0, 200, 375, and 750 mg/kg/day. Females were sacrificed on Gestation Day 20 and cesarean sections performed. The fetuses were weighed, sexed, measured for crown-rump length...

The chlorinated phenols are widely used in chemical industries for the manufacturing of herbicides, insecticides, etc. However, due to consistent use they create hazards to the environment. This study was designed to use an alternative method i.e. biofield energy treatment and analyse its impact on the physicochemical properties of 2,4-dichlorophenol (2,4DCP), which are the important factors re...

The termicidal activity and chemical components of wood vinegar from two sources biomass, nipah fruit shells (NFS) a mixture fiber (MSF), were evaluated against Coptotermes curvignathus. A no-choice test was carried out to evaluate their using filter paper samples treated with 2.5%, 5.0%, 7.5%, 10.0%, 12.5% NFS or MSF vinegar. Both vinegars exhibited antitermitic C. results show that increased ...

A diverse collection of actinomycete strains were screened for production of extracellular peroxidase activity by adapting a chemiluminescence analysis system developed for horseradish peroxidase-based enzyme-linked immunosorbent assay. Extracellular peroxidase activity was found to be common but quantitatively variable, and this rapid and sensitive screening system permitted identification of ...
