Bioconcentration and Metabolism of the New Herbicide Methiozolin in Ricefish ().

Methiozolin is a novel herbicide used to control annual bluegrass. It has low vapor pressure and high hydrophobicity, which could result in persistence in water and bioaccumulation. We measured the bioconcentration factors (BCFs) of methiozolin in ricefish ().

Dissipation of Herbicide Methiozolin and Its Metabolites in Aerobic Sediment-Water Systems.

Methiozolin is a novel herbicide for controlling annual bluegrass. After applying C labelled methiozolin in two sediment (clay loam and sand)-water systems under aerobic conditions, its distribution, half-life, and metabolites within 300 days were investigated. The mass balance ranged within 92.

Anaerobic Degradation of [C]Methiozolin under Aquatic Sediment Conditions.

The fate of methiozolin under anaerobic conditions was investigated in clay loam with a high organic carbon content and sandy loam with a low carbon content using [dihydroisoxazole ring-C] and [phenyl-C] radiolabels. The sediment/water ratio was 1:3 based on the dry weight:volume (w/v) ratio; the incubations lasted up to 355 days after the treatment (DAT) and were performed in the dark at 20.4 ± 0.

Photocatalytic Degradation Effect of -Dielectric Barrier Discharge Plasma Treated Titanium Dioxide Nanoparticles on Environmental Contaminant.

This study focused on the photocatalytic degradation effect of the μ-dielectric barrier discharge (μ-DBD) plasma treated titanium dioxide (TiO2) nanoparticles on environmental contaminant such as formaldehyde. TiO2 nanoparticles were treated by a μ-DBD plasma source with nitrogen gas. We analyzed the degradation of formaldehyde with the plasma treated TiO2 nanoparticles by UV-visible spectrophotometer (UV-VIS), and demonstrated that the photocatalytic activity of the μ-DBD plasma-treated TiO2 nanoparticles showed significantly high catalytic efficiency rather than without plasma treated TiO2 nanoparticles.

Patterned Well-Aligned ZnO Nanorods Assisted with Polystyrene Monolayer by Oxygen Plasma Treatment.

Zinc oxide is known as a promising material for sensing devices due to its piezoelectric properties. In particular, the alignment of ZnO nanostructures into ordered nanoarrays is expected to improve the device sensitivity due to the large surface area which can be utilized to capture significant quantities of gas particles. However, ZnO nanorods are difficult to grow on the quartz substrate with well-ordered shape.

Patterning ITO by Template-Assisted Colloidal-Lithography for Enhancing Power Conversion Efficiency in Organic Photovoltaic.

Highly structured interfaces are very desirable in organic photovoltaic solar cells (OPVs), in order to enhance power conversion efficiency (PCE) by decreasing of the transport path for excited charge carriers in the absorber and increasing the optical path length for photon absorption. Many complicated, high-cost lithographic methods have been attempted to modify the surface of the absorber or substrate. However, solution-based colloidal-lithography processes are scalable and cost-effective, but generally result in non-uniform structured surfaces.

The Effect of Sodium Dodecyl Sulfate on PEDOT:PSS and Its Application to Organic Photovoltaic Solar Cells.

Unlabelled: Recently, the use of

Pedot: PSS in flexible device electrodes has been reported.

Pedot: PSS treatment consists of a step in which a small amount of surfactant is added to enhance the adhesion between

Pedot: PSS and the substrate or TCO materials. However, basic research into the effect of the surfactant is lacking.

Flow Manipulation in Thread-Based Microfluidics by Tuning the Wettability of Wool.

Recent progress in thread-based microfluidic devices has provided portable and inexpensive field-based technologies enabling medical diagnostics, environmental monitoring, and food safety analysis. However, capillary-driven liquid flow in a single thread, a crucial aspect of thread-based microfluidics, is difficult to control. Among potential materials, hydrophobic wool thread is an appropriate candidate for liquid flow control in thread-based microfluidics because its wettability can be readily tuned by the introduction of a natural color pigment, thereby manipulating flow.

Developmental toxicity assessment of the new turf herbicide, methiozolin ([5-(2,6-difluorobenzyl)oxymethyl-5-methyl-3,3(3-methylthiophen-2-yl)-1,2-isoxazoline]), in rabbits.

Methiozolin is a new herbicide to control annual bluegrass (Poa annua L.) and large crabgrass (Digitaria sanguinalis (L.) Scop.

Structuring poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) towards enhancing hole collection efficiency.

Unlabelled: To date, organic photovoltaic devices (OPVs) have obtained relatively low power conversion efficiency, mostly because of the low charge carrier mobility of the polymers to be used. This limits the optimal film thickness for efficient absorption of the solar spectrum. The capability of efficient charge carrier collections is a main factor for utilizing thick OPVs, consequently enhancing the power conversion efficiency.

Micropatterning of TiO2 thin films by MOCVD and study of their growth tendency.

In this work, we studied the growth tendency of TiO2 thin films deposited on a narrow-stripe area (<10 μm). TiO2 thin films were selectively deposited on OTS patterned Si(100) substrates by MOCVD. The experimental data showed that the film growth tendency was divided into two behaviors above and below a line patterning width of 4 μm.
