A localized heating structure includes a spectrally-selective solar absorber, that absorbs incident solar radiation and reflects at wavelengths longer than 2 m, with an underlying heat-spreading layer having a thermal conductivity equal to or greater than 50 W/(mK), a thermally insulating layer, adjacent to the spectrally-selective solar absorber, having a thermal conductivity of less than 0.1 W/(mK), one or more evaporation openings through the spectrally-selective solar absorber and the thermally insulating layer, and an evaporation wick, disposed in one or more of the evaporation openings in the thermally insulating layer, that contacts liquid and allows the liquid to be transported from a location beneath the thermally insulating layer through to the spectrally-selective solar absorber in order to generate vapor from the liquid. The thermally insulating layer is configured to have a density less than the liquid so that the localized heating structure is able to float on the liquid.

A material contains open pores in which the channels and pores that are internally coated with at least one layer of phosphorus-containing alumina. Such material is formed by infiltrating a porous material one or more times with a non-colloidal, low-viscosity liquid coating precursor, drying, and curing the coating precursor to form a phosphorus-containing alumina layer within pores of the material.

A system and method for positioning a pill to be ingested by a user in a field of view of an image acquisition camera. The method includes the steps of determining a desired location of the mouth of a user in a field of view of an image acquisition camera, determining a current position of a pill to be ingested by the user in the field of view of the image acquisition apparatus, and indicating on a display a movement to be made by the user to move the pill towards mouth of the user.

The present disclosure provides articles that include polymer coatings on substrates primed with a primer coating containing silica nanoparticles, and methods of coating. The polymer coating is preferably a silicone-based polymeric material.
