Primary investigation of the optical limiting performance of cyclo[8]pyrrole with a wide optical limiting window

Cyclo[8]pyrrole (CP) was prepared and its UV/vis spectral and optical limiting properties for ns light pulse were investigated withZ-scan technical.

Functionalized bio-artifact fabricated via selective slurry extrusion. Part 2: Fabrication of ceramic dental crown

Functionalized ceramic dental crown was successfully fabricated through selective slurry extrusion (SSE) based technique of solid freeform fabrication (also known as rapid prototyping). After sintering, the decomposed tourmaline powders were embedded in ZrO2 matrix. The far infrared emission properties of the ceramic dental crown were improved due to the increase of the numbers of infrared active bonds from tourmaline. This new dental restoration process presents potential to provide dental patients with functionalized artificial teeth, which benefits the body health by the way of emitting far infrared rays in ambient temperatures.

[Climbing-upward inhibition of Oncomelania hupensis by niclosamide combination]

OBJECTIVE

To develop a combination of molluscicide/insecticide with a good molluscicidal effect, especially an inhibitory effect on climbing-upward of Oncomelania hupensis.

METHODS

Experiments on molluscicidal and snail-climbing inhibition effect of the combination of niclosamide and shachongding [(dimethylamine) trithacyclohexane hydrochloride] were conducted by immersion and spraying in laboratory.

RESULTS

The combination of niclosamide (0.2 mg/L) and shachongding (0.1 mg/L) showed an inhibition of 92.67% of snails to climb up. There was no significant difference in molluscicidal effect between the combination (LC90 0.198 mg/L) and niclosamide alone (LC90 0.207 mg/L).

CONCLUSION

The combination showed an effective inhibition on the climbing-upward of snails in water so as to improve the molluscicidal effect and reduce the cost of mollusciciding.

Binary cooperative complementary nanoscale interfacial materials

Binary cooperative complementary nanoscale interfacial materials, i.e, materials with two complementary properties on the nanoscale, are introduced as a new concept for the design of functional materials. The concept is based on the generation of nanostructures with mutually compensating properties on the surface of a solid. Under certain coordinating conditions, unexpected properties may often appear at these kinds of interfaces, creating a huge potential for applications and theoretical research. Recent research indicates that the binary cooperative complementary concept is extremely useful for the design and creation of nanoscale functional materials.
