in this work, spherical pt nanometer-scale particles supported on the poly (m-toluidine)/triton x-100 film modified carbon nanotube paste electrode (pt/pmt (tx-100)/mcntpe) was used as a potent catalyst for electrooxidation of formaldehyde (hcho) in both 0.5 m h2so4 and 0.1 m naoh solutions. the obtained results showed that utilization of tx-100 as an additive during the electropolymerization p...

Denture hygiene is essential because denture biofilm is involved in oral infections and systemic diseases. Although there are chemical agents available on the market, none of them have ideal properties and research on such products is still necessary. The aim of this study was to evaluate the efficacy of a castor bean (Ricinus communis)-based solution for removing denture biofilm, compared to t...

Surface texturization is well known as one of the major paths to improve the conversion efficiency of silicon solar cells by increasing the short-circuit current through the enhancement in antireflection property and effective photon trapping. Compared to the antireflection coating, it is more lasting and effective process. The anisotropic texturing of a (100) n-type monocrystalline silicon sur...

This research study describes recent advances in understanding the effects of addition organic acids, such as acetic, lactic, citric and phytic on process plasma electrolytic oxidation (PEO) Ti using an alkaline bath. As developed over workpiece is central to determine particular morphological structural features growing oxide, focus then inter-relationships between electrolyte resultant regime...

An 'anomalous' negative flux, in which carbon dioxide (CO2) enters rather than is released from the ground, was studied in a saline/alkaline soil. Soil sterilization disclosed an inorganic process of CO2 dissolution into (during the night) and out of (during the day) the soil solution, driven by variation in soil temperature. Experimental and modeling analysis revealed that pH and soil moisture...
