Provides a non-white construction surface comprising a substrate, a first reflective coating on at least a portion of an outer surface of the substrate, the coated substrate exhibiting a minimum direct solar reflectance value of at least about 25%, and a second reflective coating on at least a portion of the first reflective coating, wherein the combination of the first reflective coating and the second reflective coating provide the substrate with a CIELAB L* lightness value of less than about 69, and at least one of (i) a reflectivity of at least about 20% at substantially all points in the wavelength range between 770 and 2500 nm; and (ii) a summed reflectance value of at least 7000 as measured in the range between 770 and 2500 nm inclusive. Also provided are various substrates having the coatings described as well as methods of providing the described construction surfaces.

A method for the preparation of a perfluorinated acid fluoride (especially 3-alkoxy propionic acid fluoride) is provided. The method results in high yields of the acid fluoride.

Perfluorinated acid fluorides and preparation thereof

The present invention provides a method of detecting a short incident in an electrochemical cell (e.g., a Simons electrochemical fluorination cell or bipolar flow cell) using means for detecting vibration to detect vibration of an external piece on the cell. The present invention further provides a system for detecting a short incident in an electrochemical cell.
