A reagent-less sensing probe has been developed using hydrothermally reduced graphene oxide (HRGO) and investigated as potentiometric chemiresistive pH sensor. The HRGO modified electrode, used a probe, showed sensitivity of 66 mV / for freshly prepared electrode. After few exposures to different buffers, stable 55 was obtained in range from 2 12. In the mode, electrode around 44 Ω 4 7. results...

Reactive oxygen species (ROS) regulate ion channels, modulate neuronal excitability, and contribute to the etiology of neurodegenerative disorders. ROS differentially suppress fast "ball-and-chain" N-type inactivation of cloned Kv1 and Kv3 potassium channels but not of Kv4 channels, likely due to a lack of reactive cysteines in Kv4 N-termini. Recently, we discovered that N-type inactivation of ...

The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

The nitrofurazone (NF) electrochemical reduction has been studied by cyclic voltammetry (CV) and square wave (SWV) in non-aqueous medium using three different ionic liquids (IL): BMImTf2N, BMImBF4 BMMImTf2N, having a carbon fiber microelectrode as working electrode. In all of them, two reversible cathodic peaks were recorded for NF. Under higher frequency values, only one peak was registered. s...

During drinking water treatment, advanced oxidation process (AOP) with O3 and H2O2 may result in by-products, residual BrO3?. The containing BrO3? often flows into subsequent granular activated carbon (GAC) filters. A concentrated solution can be used as GAC modification reagent at 60 °C to improve its adsorption ability. However, whether low concentrations of residuals from AOP modify GAC, the...

Cycle-linear hybrid automata (CLHAs), a new model of excitable cells that efficiently and accurately captures action-potential morphology and other typical excitable-cell characteristics such as refractoriness and restitution, is introduced. Hybrid automata combine discrete transition graphs with continuous dynamics and emerge in a natural way during the (piecewise) approximation process of any...

ous chemical or electrochemical systems mimicking monooxygenase enzymes have been reported. Among these oxygenation models, studies on chemical systems using iron(III) picolinate (Fe(PA)3) or iron(II) picolinate (Fe (PA)2) complexes as catalysts have been reported under various conditions and in various solvents. We are interested in stereoselective oxidation reactions, especially 7a-hydroxylat...

Stringent alarmone, namely, guanosine 3'-diphosphate-5'-diphosphate (ppGpp), is a global regulator that plays a critical role in the survival, growth, metabolism, and many other vital processes of microorganisms. Because of its structural similarity to normal nucleotides, it is also a challenge for the selective and sensitive detection of ppGpp nowadays. Herein, we developed a colorimetric meth...
