Tin bisulfide nanoplates anchored onto flower-like bismuth tungstate nanosheets for enhancement in the photocatalytic degradation of organic pollutant.

The development of efficient heterojunctions through a simple and facile method is an effective way to enhance the photocatalytic performance of bismuth-based oxide semiconductors for industrial applications. Here, the novel flower-like type II SnS/BiWO heterostructure consisting of bismuth tungstate (BiWO) nanosheets and tin bisulfide (SnS) nanoplates was successfully designed and synthesized. The crystal structure, composition, morphology, and photoelectric properties of the heterostructure were systematically characterized.

Enhanced photocatalytic degradation of glyphosate over 2D CoS/BiOBr heterojunctions under visible light irradiation.

Two-dimensional (2D) heterojunction photocatalysts can shorten the carrier transfer pathway. In this study, CoS nanoparticles were deposited on the surface of 2D BiOBr nanosheets to fabricate novel ultrathin and intimate-contact 2D heterojunction photocatalysts by a two-step solvothermal route. Under visible-light (λ > 400 nm) irradiation, the apparent reaction rate constant of glyphosate degradation over 10%CoS/BiOBr reaches 0.

Fabrication of hierarchical copper sulfide/bismuth tungstate p-n heterojunction with two-dimensional (2D) interfacial coupling for enhanced visible-light photocatalytic degradation of glyphosate.

Hierarchical copper sulfide/bismuth tungstate (CuS/BiWO) p-n junction with two-dimensional (2D) interfacial coupling were prepared through a two-step hydrothermal method. The as-prepared samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, diffuse reflectance spectroscopy, photoluminescence spectroscopy, photocurrent and electrochemical impedance spectroscopy. CuS nanoplates anchored on the surface of hierarchical BiWO microspheres consisting of BiWO nanosheets to form a CuS/BiWO p-n junction photocatalyst.

Two-step hydrothermal synthesis of peanut-shaped molybdenum diselenide/bismuth vanadate (MoSe/BiVO) with enhanced visible-light photocatalytic activity for the degradation of glyphosate.

The novel peanut-like shaped MoSe/BiVO composites were fabricated via a facile two-step hydrothermal method and their photocatalytic activity was evaluated by the degradation of glyphosate under the visible light irradiation. The efficient transfer of photogenerated carriers and the charge separation were confirmed by photoluminescence spectra (PL), electrochemical impedance spectroscopy (EIS) and photocurrent. The coupling of MoSe and BiVO remarkably enhanced the photocatalytic activity.

Nickel sulfide/graphitic carbon nitride/strontium titanate (NiS/g-CN/SrTiO) composites with significantly enhanced photocatalytic hydrogen production activity.

NiS/g-CN/SrTiO (NS/CN/STO) composites were prepared using a facile hydrothermal method. The synergistic effect of g-CN/SrTiO (CN/STO) heterojunction and NiS cocatalyst enhanced the photocatalytic hydrogen evolution activity of NS/CN/STO. A hydrogen production rate of 1722.

The impact of PM2.5 on the human respiratory system.

Recently, many researchers paid more attentions to the association between air pollution and respiratory system disease. In the past few years, levels of smog have increased throughout China resulting in the deterioration of air quality, raising worldwide concerns. PM2.

Effect of protein-tyrosine phosphatase 4A3 by small interfering RNA on the proliferation of lung cancer.

Previous studies on PTP4A3 mainly focused on tumor metastasis due to the close relationship between the overexpression of lung cancer and metastasis. However, the role of PTP4A3 in the proliferation of tumor still has remained unclear. To investigate the role of PTP4A3 in cell growth of lung cancer, we constructed PTP4A3-siRNA expressing lentivirus and infected human lung cancer H1299 cells, and then examined the inhibitory effect of PTP4A3 in vitro.

B7-H3 and CD133 expression in non-small cell lung cancer and correlation with clinicopathologic factors and prognosis.

Objective: To detect the expression of B7-H3 and CD133 in human non-small cell lung cancer (NSCLC) specimens and lung benign lesions, and to evaluate the correlation between the 2 biomarkers and clinicopathologic features.

Methods: This is a case-control study of 102 tissue specimens collected from NSCLC participants undergoing thoracic surgery in the Second Affiliated Hospital of Soochow University, Suzhou, China, between January 2006 and December 2008. From the 102 patients, 25 adjacent non-cancer samples were verified pathologically as normal tissue (positive group), and 24 benign inflammatory lesion tissues were used as control (negative group).

[Changing characteristics of temperature and humidity in different type bags for bagging apple and their effects on fruit appearance quality].

This paper studied the changing characteristics of temperature and humidity in different type bags for bagging Fuji apple during its development and their effects on the appearance quality of the fruit. The results showed that there was a negative correlation between the changes of temperature and humidity in the bags. Temperature started to rise rapidly from 9:00, with the highest appeared generally from 13:00 to 14:00 in spring and autumn or from 13:00 to 17:00 in mid-summer, while the lowest at about 5:00.

[Correlation of the (rotation) traction force with the pressure in the nucleus pulposus in multiple segments of the cervical vertebra].

Objective: To study the correlation between cervical (rotation) traction force and the pressure in the cervical nucleus pulposus based on an examination of multiple segments of the cervical vertebra.

Methods: The data obtained from our observation were processed by the exponential model, and the changes in the pressure reduction (P) in the cervical nucleus pulposus were analyzed.

Results: When stretching followed by rotation was imposed on the cervical vertebra, an increase of P was first observed due to the stretching before a reduction in P caused by the rotation.
