Enhanced interfacial effect via acid theory with boosted photocatalytic performance of nitenpyram removal.

Surface reaction is a prominent aspect that affects the efficiency of photocatalysis. In this work, acid theory was employed to facilitate the reaction dynamics and enhance the interfacial effect between photocatalysts and target molecules. The photocatalytic removal efficiency of NTP was 66 % for bare CdS in 50 min with apparent rate constants of 0.

In Situ Fabrication of CdS/Cd(OH) for Effective Visible Light-Driven Photocatalysis.

Photocatalytic hydrogen production is a promising technology that can generate renewable energy. However, light absorption and fast electron transfer are two main challenges that restrict the practical application of photocatalysis. Moreover, most of the composite photocatalysts that possess better photocatalytic performance are fabricated by various methods, many of which are complicated and in which, the key conditions are hard to control.

Transcriptome responses to heat stress in hypothalamus of a meat-type chicken.

Background: Heat stress has resulted in great losses in poultry production. To address this issue, we systematically analyzed chicken hypothalamus transcriptome responses to thermal stress using a 44 k chicken Agilent microarray.

Methods: Hypothalamus samples were collected from a control group reared at 25°C, a heat-stress group treated at 34°C for 24 h, and a temperature-recovery group reared at 25°C for 24 h following a heat-stress treatment.

Effect of dissolved oxygen on nitrogen purification of microbial ecosystem in sediments.

Key groups of nitrogen transforming bacteria and enzyme activities in sediments developed in response to dissolved oxygen (DO) concentration were investigated at four different oxygen supply levels, namely, oxygen saturation condition (DO = 8.60 mg L(-1)), aerobic condition (DO = 6.00 mg L(-1)), anoxic condition (DO = 2.

Tolerance and biosorption of copper and zinc by Pseudomonas putida CZ1 isolated from metal-polluted soil.

A strain of Pseudomonas sp. CZ1, which was isolated from the rhizosphere of Elsholtzia splendens obtained from the heavy-metal-contaminated soil in the north-central region of the Zhejiang province of China, has been studied for tolerance to copper (Cu) and zinc (Zn) and its capacities for biosorption of these metals. Based on 16S ribosomal DNA sequencing, the microorganism was closely related to Pseudomonas putida.

Uptake and accumulation of phenanthrene and pyrene in spiked soils by Ryegrass (Lolium perenne L.).

Phytoremediation has long been recognized as a cost-effective method for the removal of polycyclic aromatic hydrocarbons (PAHs) from soil. A study was conducted to investigate the uptake and accumulation of PAHs in root and shoot of Lolium perenne L. Pot experiments were conducted with series of concentrations of 3.
