Highly Efficient Removal of 2,4,5-Trichlorophenoxyacetic Acid by Adsorption and Photocatalysis Using Nanomaterials with Surface Coating by the Cationic Surfactant.

Extensive removal of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) using titania (TiO) nanoparticles by adsorption and photocatalysis with a surface coating by cetyltrimethylammonium bromide (CTAB) is reported. The CTAB-coated TiO nanoparticles (CCTN) were characterized by FT-IR, zeta-potential measurements, and UV-vis diffuse reflectance spectroscopy (UV-vis-DRS). 2,4,5-T removal increased significantly after surface modification with CTAB compared with bare TiO nanoparticles.

Facile route for preparation of cuprous oxide/copper/cupric oxide nanoparticles by using simultaneous electrochemical and reduction reaction.

Cuprous oxide/copper/cupric oxide nanoparticles were synthesized through a hybrid process involving anodic dissolution and a controlled redox reaction between NaOH and glucose in the solution. The study demonstrates the structural manipulation of the material by varying the reaction components within the solution. Morphology, structural analyses using SEM (Scanning Electron Microscope), EDX (Energy-dispersive X-ray spectroscopy), TEM (Transmission Electron Microscope), FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-ray diffraction), and XPS (X-ray photoelectron spectroscopy) unveiled the tunability of the material's structure based on the reaction components.

Synthesized uniform-different sizes silver nanoparticles using TSC and SBH simultaneously for antibacterial application.

Silver nanoparticles (AgNPs) in the form of nanospheres from a few nm to 100 nm in diameter were synthesized in a controlled manner using a combination of two reducing agents: sodium borohydride (SBH) and trisodium citrate (TSC). The influence of the size of AgNPs on antibacterial activity was investigated with different concentrations of AgNPs on two types of bacteria:(PA) andresistant (SA) while the positive control was50g/ml and the negative control was water. AgNPs were investigated for morphology, size and size distribution using transmission electron microscopy (TEM) and dynamic light scattering (DLS) measurements.

Greener Method for the Application of TiO Nanoparticles to Remove Herbicide in Water.

TiO nanoparticles have emerged as a great photocatalyst to degrade organic contaminants in water; however, the nanoparticles dispersed in water could be difficult to be recovered and potentially become contaminant. Herbicide like 2,4-dichlorophenoxyacetic acid (2,4-D) used in agriculture usually ends up with a large fraction remaining in water and sediment, which may cause potential risk to human health and the ecosystem. This study proposes a greener method to utilize TiO as photocatalyst to remove 2,4-D from water.

Labdane- diterpenoids and sesquiterpenes from and their nitric oxide inhibitory activity in lipopolysaccharide-stimulated RAW264.7 macrophages.

One new labdane- diterpenoid, 3,15-dihydroxylabda-8(17),12-dien-16,15-olide () named curcumatin and twelve known compounds, coronarin D (), isocoronarin D (), ()-labda-8(17),12-diene-15,16-dial (), zerumin A (), ()-labda-8(17),12-dien-15,16-dioic acid (), furanodiene (), linderazulene (), zedoarol (), zedoarondiol (), germacrone-1,10-epoxide (), germacrone-4,5-epoxide (), and zingiberenol () were isolated from the ethanol extract of the roots of Salisb. Their structures were elucidated by 1D-, 2D-NMR spectroscopic analysis, HR-ESI-MS, and comparing with the NMR data reported in the literature. Compounds , , and significantly inhibited the nitric oxide production effect in LPS-stimulated RAW 264.

Effects of Compound Trace Minerals on the Growth Performance, Carcass Characteristics and Meat Quality of Fattening Pigs.

The objective of this study was to evaluate the effects of supplemental levels of compound minerals (CM), which was formulated from a mixture of 300 mg calcium, 150 mg magnesium, 25 mg zinc, 15 mg iron, 4 mg manganese, and 2 mg copper per gram, on the growth performance and feed conversion ratio of Duroc × (Landrace × Yorkshire) fattening pigs. A total of 53 female pigs and 45 male pigs at 35 days of age were individually notched and randomly allocated to three treatments, including0 (basal diet), 0.5 (basal diet with 0.

A household survey on morbidity and treatment of acute respiratory infections in communities in Vietnam.

Objective: To ascertain the extent of under-utilization and insufficiency or inappropriateness in provision of health services as one of the possible causes of high mortality from pediatric pneumonia in pilot areas in Vietnam.

Method: The household survey on morbidity and treatment of acute respiratory infections, simple cough, and cold and pneumonia, was conducted in two communities with 10% sampling of the child population.

Results: Both under-treatment of "fast breathing", a proxy for pneumonia, and over-treatment of simple cough and cold with antimicrobials by health workers, mothers, and private practitioners were common.
