When the modification is carried out in an aqueous solution, it leads to the formation of silica around the C-dots and an increase of luminescence, but also to the formation of large clusters which do not allow the deposition of optically transparent films. On the contrary, when the C-dots...
Cobalt glass absorbs light in the yellow wavelengths, but is transparent to light of higher energy (this is why it looks blue!). Viewing a yellow flame through cobalt glass will allow you to see if there is any higher energy light present. No cobalt blue glass filters in ou...

3(d) shows an OCT image of a transparent microneedle of similar geometry in a healthy volunteer Full size image Modelling the electrochemical behaviour of microneedle array electrodes Since there is no cited work on the diffusion profile of pyramidal microneedle array electrodes, the microneedle array...
includes a window optically coupled to an ultraviolet light source, an ultraviolet light source operable to direct ultraviolet light onto the window, and a photo-activated catalyst layer applied to the window, wherein the photo-activated catalyst layer is optically transparent at certain wavelength ...
Background The work aims at improving photocatalytic activity of titania under Vis light irradiation using modification by Sn ions and an original, simple synthesis method. Tin-doped titania catalysts were prepared by thermal hydrolysis of aqueous solutions of titanium peroxo-complexes in the presence ...
1. A self indicating peroxycarboxylic acid chemistry composition comprising: a peroxycarboxylic acid; a background dye; and at least two latent peracid selective dyes which upon oxidation by the peroxycarboxylic acid provides a tri-color visual indication of the presence of a minimum concentration ...
