This research was conducted to synthesis and application for high oxygen permeable ophthalmic lens materials. 2-(Trimethylsiloxy)ethyl methacrylate (2T), 3-[Tris(trimethylsiloxy)silyl]propyl methacrylate (3T), [(1,1-Dimethyl-2-propynyl)oxy]trimethylsilane (TMS), Poly(ethylene glycol) methyl ether methacrylate (PEGMA), N-vinyl-2-pyrrolidone (NVP) and titanium carbide nanoparticles were used as additives for the basic combination of synthesized silicone monomer (SiD) and N,N-Dimethylacetamide (DMA). And also, the materials were copolymerized with ethylene glycol dimethacrylate (EGDMA) as the cross-linking agent, azobisisobutyronitrile (AIBN) as the initiator. The copolymerization with a small amount of silane of about 1% increased the oxygen permeability to 30.3˜33.52(cm2/sec)·(mlO2/ml·mm Hg)·10−11, and in particular, the addition of titanium carbide nanoparticles was found to increase to 46.38 (cm2/sec)·(ml O2/ml·mm Hg)·10−11. Surface modification was possible with various wetting agents. Especially, simultaneous use with titanium carbide nanoparticles increased the wettability while maintaining water content. These materials are considered to make synergy effect each other, so it can be used in functional hydrogel ophthalmic lenses.

Chamelaucium Uncinatum

In postharvest dipping treatment of Geraldton waxflower (Chamelaucium uncinatum), 13 insecticides tested at recommended application rates caused no visual injury, but some reduced vase life. Flowers of cv. Purple Pride were more sensitive to insecticides than leaves. There was no loss of vase life of flowers following dipping in chlorpyrifos, dimethoate or permethrin. Following dipping in deltamethrin, carbaryl, dichlorvos, cypermethrin, endosulfan or fenvalerate there was 31-49% loss of vase life. No loss of vase life was observed for cv. Alba, after dipping in carbaryl, fenvalerate or dimethoate. Insecticide dips containing wetting agent and a fungicide (e.g. a combination of deltamenthrin, Aqua and benomyl) was a suitable dip for Geraldton waxflower. Wetting agents varied in their effect on vase life. Aqua shortened vase life less than Agral, and D-CTrate less than D-C-Tron. Stems rapidly lost weight when held out of water following dipping, and vase life was reduced when ambient temperatures were above 30�C or drying times exceeded 60 min. It was concluded that flowers should be kept cool and well hydrated following dipping treatment.

The Impact

Pseudomonas aeruginosa is a motile bacterium able to exhibit a social surface behaviour known as swarming motility. Swarming requires the polar flagellum of P. aeruginosa as well as the secretion of wetting agents to ease the spread across the surface. However, our knowledge on swarming is limited to observed phenotypes on agar-solidified media. To study the surface behaviour and the impact of wetting agents of P. aeruginosa on other surfaces, we assessed surface motility capabilities of the prototypical strain PA14 on semi-solid media solidified with alternative gelling agents, gellan gum and carrageenan. We found that, on these alternative surfaces, the characteristic dendritic spreading pattern of P. aeruginosa is drastically altered. One striking feature is the loss of dependence on rhamnolipids to spread effectively on plates solidified with these alternative gelling agents. Indeed, a rhlA-null mutant unable to produce its wetting agents still spreads effectively, albeit in a circular shape on both the gellan gum- and carrageenan-based media. Our data indicate that rhamnolipids do not have such a crucial role in achieving surface colonization of non-agar plates, suggesting a strong dependence on the physical properties of the tested surface. The use of alternative gelling agent provides new means to reveal unknown features of bacterial surface behaviour.
