We report spectroelectrochemical and transient absorption spectroscopic studies of electron injection from the plant pigment betanin (Bt) to nanocrystalline TiO2. Spectroelectrochemical experiments and density functional theory (DFT) calculations are used to interpret transient absorption data in terms of excited state absorption of Bt and ground state absorption of oxidation intermediates and ...

The effects of pH (3.6 and 7.0) irradiation UV-C dose (0, 9.81, 15.13, 31.87 mJ/cm2) on the physicochemical properties natural microbiota red prickly pear juice were evaluated during processing storage. Thermal treatments used as control applying high temperatures for a short time (HTST 80 °C/30 s) or ultra-high temperature (UHT 130 °C/3 s). applied to juices with both pHs inactivated coliforms...

Background: A photovoltaic cell, or solar is an electronic component which, exposed to light, produces electricity due the effect. Organic cells are cells, of which at least active layer consists organic molecules. It has a yield 15%. The future prospects research for cell application have been required development in field. Objectives: In this work, we propose paper study potential purified be...

This study evaluates the effects of polyphenolic extract Cistus incanus, lycopene dye from tomatoes, and betanin red beet on selected parameters model meat products with reduced nitrate contents. The composition activity C. incanus was analyzed, revealing presence elagotannins, flavanols, glycosylated flavanols. We studied dyes as well mixtures growth bacteria characteristic environment: E. col...

Fluorescent 3H-indolium cations are valuable components for the realization of activatable fluorophores for bioimaging applications. Their relatively poor fluorescent quantum yields in organic solvents, however, appear to be in contradiction to their good performance in analytical methods based on single-molecule detection. The elucidation of the structural factors governing the excitation dyna...

The inhibition efficiency (IE) of an aqueous extract of beet root (BR) in controlling corrosion of carbon steel in well water in the absence and presence of Zn 2+ has been evaluated by mass loss method. The formulation consisting of 4 mL of BR extract and 50 ppm Zn 2+ offers 98% inhibition efficiency to carbon steel immersed in well water. A synergistic effect exists between BR extract and Zn 2...
