The influence of strain on catalytic activity has previously been examined directly by calculations and indirectly by experiments. The origin of the phenomenon has been attributed to strain-induced changes in the catalyst electronic structure. By employing a Pd-based metallic glass film capable of large elastic strains, we provide direct experimental evidence for catalytic activity being differ...

A direct and label-free electrochemical biosensor for the detection of the protein-mismatched DNA interaction was designed using immobilized N-terminal histidine tagged Escherichia coli. MutS on a Ni-NTA coated Au electrode. General electrochemical methods, cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM) and impedance spectroscopy, were used to ascertain the binding ...

In this project, we have attempted to develop a new technique utilizing Boron-doped diamond (BDD) films to electrochemically detect mercury dissolved in solution via the initial deposition of metallic mercury, followed by anodic linear sweep voltammetry in the range from 1010 M to 10 M. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques were employed. The extremely low ...

The formation of mixed self-assembled monolayers (SAMs) from novel biotinylated alkylthiols (BAT) and diluent triethyleneglycol (TEG) alkylthiols on gold has been accomplished using aqueous solvents. We compare the effects of aqueous and ethanolic solvents on the binding performance of mixed SAMs and the integrity of monolayers formed. We use cyclic voltammetry (CV) and fluorescence microscopy ...

The speed at which two remote parties can exchange secret keys over a fixed-length fiber-optic cable in continuousvariable quantum key distribution (CV-QKD) is currently limited by the computational complexity of post-processing algorithms for key reconciliation. Multi-edge low-density paritycheck (LDPC) codes with low code rates and long block lengths were proposed for CV-QKD, in order to exte...

The present work describes a new approach to directly electrodeposit platinum nanoparticles on the surface of multi-walled carbon nanotubes (MWNTs) through cyclic potential scanning technique and to prepare a novel carbon nanotubes including platinum nanoparticles modified electrode (noted as Pt/MWNTs). TEM image shows that Pt nanoparticles are attached on the out surface of the MWNTs with aver...

This paper deals with the development of an electrochemical sensor base on Trypan Blue (TB) towards the determination of Dopamine (DA). An electrochemical sensor was fabricated by the electropolymerization of TB onto the Carbon paste electrode (CPE) using cyclic voltammetry (CV) technique. The polymerized TB modified CPE (Poly(TB)MCPE) was characterized using Electrochemical impedance spectrosc...

A highly sensitive electrochemical method for trace-level detection of acetaminophen (AMP) was employed using glucose-based carbon electrode (Gu/CPE) by cyclic voltammetry (CV) and differential pulse (DPV). Electrochemical properties AMP were well suited in 0.2 M phosphate buffer solution (PBS) pH 7.0 peak intensity at the Gu/CPE enhanced compared to bare paste electrode. Furthermore, different...

Cyclic electron flow around photosystem (PS) I has been widely described in vitro in chloroplasts or thylakoids isolated from C(3) plant leaves, but its occurrence in vivo is still a matter of debate. Photoacoustic spectroscopy and kinetic spectrophotometry were used to analyze cyclic PS I activity in tobacco (Nicotiana tabacum cv Petit Havana) leaf discs illuminated with far-red light. Only a ...
