A modest, efficient, and sensitive chemically modified electrode was fabricated for sensing curcumin (CRC) through an electrochemically polymerized titan yellow (TY) carbon paste (PTYMCPE) in phosphate buffer solution (pH 7.0). Cyclic voltammetry (CV) linear sweep (LSV) differential pulse (DPV) approaches were used CRC detection. PTYMCPE interaction with suggests that the exhibits admirable ele...

The various criteria used for graduating the thickness of violin plates are discussed. These are shown apparently to be conflicting. A case is made that the flexural stiffness of the plates should be given priority. A simple indirect method is given for finding the flexural stiffness of the plates without the need to flex them in the hands or to apply forces and measure deflections. The method ...

Security protocols are small programs that are executed in hostile environments. Many results and tools have been developed to formally analyze the security of a protocol in the presence of an active attacker that may block, intercept and send new messages. However even when a protocol has been proved secure, there is absolutely no guarantee if the protocol is executed in an environment where o...

In this paper, a reflection is made on an indeterminism inherent to Hopcroft’s minimization algorithm: the splitter choice. We have implemented two natural policies (FIFO and FILO) for managing the set of splitters for which we obtain the following practical results: the FILO strategy performs better than the FIFO strategy, in the case of a one letter alphabet, the practical complexity in the F...

Ni-doped Co3O4 catalysts with various Ni concentrations (0.01, and 0.015 M) were synthesized using a simple, cost-effective hydrothermal route. The samples are denoted as Co3O4-1 Co3O4-2. Structural morphological properties of as-prepared characterized by XRD, FTIR, XPS, SEM, HR-TEM techniques. electrochemical characteristics for the urea oxidation (UOR) on catalyst examined cyclic voltammetry ...

PtM/C (M = Co, Ni, Cu, Ru) catalysts were prepared by wet-synthesis methods. The composition and structure of the synthesized materials estimated TXRF, XRD, TEM, HAADF-STEM, EDX, TGA/DSC According to CV LSV methods, PtCu/C material is characterized highest activity in ORR compared other studied. PtRu/C also exhibit MOR. Studying durability obtained bimetallic using accelerated stress testing ha...

Lead–steel layered composite electrode materials have been successfully prepared by the roll bonding method. Scanning electron microscopy and energy dispersion spectroscopy (EDS) were used to analyze microstructures elements distribution at interface. The electrochemical properties of samples studied linear sweep voltammetry (LSV), Tafel curves, a weight loss analysis microstructure showed that...

In the present research, 4, 4'-biphenol was used as a homogeneous mediator for determining cysteine (CySH) on a Glassy Carbon Electrode (GCE). To describe the electrochemical properties of 4,4'-biphenol and to examine its electrocatalytic impacts on cysteine oxidation, both Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) were employed. Our findings revealed that 4,4'-biphenol could s...

A novel triphenylamine (TPA) based donor-π-acceptor (D-π-A) dye is synthesized and its optical electrochemical properties are examined by UV-Vis absorption spectroscopy cyclic voltammetry methods, respectively. The D-π-A plays a role as visible light sensitizer to wide bandgap TiO2 photocatalyst. Hydrogen evolution reaction (HER) carried out using sensitized (Dye/TiO2) under irradiation in the ...
