Effective atmospheric-pressure plasma treatment toward high performance solution-processed oxide thin-film transistors.

Solution-processed oxide semiconductors (OSs) have attracted much attention because they can simply, quickly and cheaply produce transparent channels on flexible substrates. However, despite such advantages, in the fabrication process of OS TFTs using the solution process, it is fatal problem that there are hardly any way to simply and effectively control important TFT parameters including turn-on voltage (Von) and on/off current ratio. For the practical application of solution-processed OS TFT, the approac...

Dynamics of the Selkov oscillator.

A classical example of a mathematical model for oscillations in a biological system is the Selkov oscillator, which is a simple description of glycolysis. It is a system of two ordinary differential equations which, when expressed in dimensionless variables, depends on two parameters. Surprisingly it appears that no complete rigorous analysis of the dynamics of this model has ever been given. In this paper several properties of the dynamics of solutions of the model are established. With a view to studying ...

Toc-3 showed k values larger than tho...

Hyperoxygenated Hydrogen-Rich Solution Suppresses Lung Injury Induced by Hemorrhagic Shock in Rats.

Hemorrhagic shock could induce acute lung injury (ALI), which is associated with cell hypoxia, lung tissue inflammation, free radical damage, and excessive cell apoptosis. Our previous studies demonstrated that hyperoxygenated solution could alleviate cell hypoxia. Furthermore, hydrogen-rich solution (HS) could relieve lung tissue inflammation, free radical damage and excessive cell apoptosis. Therefore we hypothesize that Hyperoxygenated Hydrogen-rich solution (HOHS) can protect the lung against ALI.

Direct Demonstration of DNA Compaction Mediated by Divalent Counterions.

We unambiguously demonstrated DNA attraction and its regulation mediated by divalent cations Mg2+ and Ca2+ by tethering a DNA single chain at various pH solutions. It is found that DNA is compacted when pH of solution containing these divalent counterions is lowered below 5. When pH of medium is about 4, DNA is in an unstable transition state, being able to switch reversely between compact and extensible states. We can also regulate the DNA attraction by a cyclic process of DNA compaction and unraveling thr...

Abdominal pumping involvement in the liquid feeding of honeybee.

Honeybee drinking is facilitated by a "mop-like" tongue, which helps honeybees suck in the sucrose solution from the environment. However, the liquid-transport mechanism from the pharynx to the crop, especially the natural link between abdominal pumping and dipping behavior on the sucrose solution intake, remains obscure. A significant increase in abdominal pumping frequency is observed when honeybees drink the sucrose solution. Abdominal pumping exhibits a function other than respiration. This second funct...

Novel rhodamine-based colorimetric and fluorescent sensor for the dual-channel detection of Cu and Co/trivalent metal ions and its AIRE activities.

A rhodamine hydrazone 1 bearing coumarin moiety was designed and prepared. Compound 1 exhibited high selectivity toward Co and trivalent metal ions with fluorescence enhancement in CHOH solution. However, 1 selectively responded to Al in nearly pure HO media and was further applied to monitor Al in live cells. Moreover, 1 could also act as a colorimetric probe toward Cu in either CHOH or HO solution. In addition, sensor 1 displayed aggregation-induced ratiometric emission (AIRE) activities in mixed HO/CHOH ...
