Photodynamic inactivation of Escherichia coli with cationic meso-tetraarylporphyrins – The charge number and charge distribution effects

“…This approach, based on the interaction of light with dispersed metallic nanoparticles or photoactivate molecules have attracted great interest due to its high efficacy. In this field a special attention is being given to metal-oxide materials like titanium dioxide (TiO 2 ), alone or doped with other noble metals such as silver, due to their chemical stability, photophysical properties and high efficiency to inactivate bacteria, moulds, and viruses [2][3][4][5][6][7]. Photoactive organic molecules, known as photosensitizers (PS), are also recognized to be effective against various microorganisms, including viruses, bacteria, yeasts, protozoa [8][9][10][11], and even drug-resistant strains [12][13][14][15][16][17], and microorganisms organized in biofilms [18,19].…”

Bifunctional Electrocatalyst of Low-Symmetry Mesoporous Titanium Dioxide Modified with Cobalt Oxide for Oxygen Evolution and Reduction Reactions

“…Consequently, recent research activities have been focused on developing effective bifunctional catalysts with greater performance and cost-effectiveness, and superior durability, for both the ORR and the OER, for widespread applications. Oxides and hydroxides based on transition metals, such as nickel, cobalt, iron, molybdenum, titanium, and tungsten, have emerged as a promising class of noble metal-free material catalysts [12][13][14]. These earth-abundant materials on various supports have been identified as high activity and stability electrocatalysts for the OER and the ORR under neutral or strongly alkaline conditions [15][16][17][18][19][20][21].…”
