The gold electrodes modified with organic compounds (frequently organic thiols and their derivates), represent a new category of devices which are widely used in molecular recognition, in special in case of biomolecules analysis. Alkanethiols are spontaneously adsorbed on the gold surface and form a monomolecular film, with a highly ordered structure, called a self-assembled monolayer (SAM). Th...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

A novel and simple method for the electrochemical modification of ordered mesoporous silica is described. A well-organized thin film of amine-functionalized ordered mesoporous silica has been deposited electrochemically on the electrode surface. The resulting amine-functionalized electrodes were then subjected to post-functionalization with catechol moieties through electrochemical generation o...

The performance of supercapacitors (SC) strongly depends on how their activated carbon (AC) electrodes were synthesized from precursor materials and pretreatments applied to them. This study investigates the effect direct filtered gamma radiations as AC. exposure doses used 0.1 kGy 6 kGy. high gamma-energy dose pretreatment broke randomly orientated graphitic crystal lattices inside AC particle...

Biopolymers emerged in recent years as a promising alternative for more sustainable manufacturing of electrochemical energy storage systems. In fact, environmentally friendly aqueous systems, fluorinated polymers are usually adopted. For this reason, substituting these with water processable binders could improve the overall environmental impact device. study, low – cost and modification chitos...

     Nafion is a perfluorinated anionic polyelectrolyte. The increasing popularity of nafion for the fabrication of redox polymer modified electrodes in recent years arises from easy fabrication, good electrical conductivity and high partition coefficients of many redox compounds in nafion. To investigate the production of nano-compositions by mixing electron transfer material and nafion polyme...
