An innovative and highly efficient light system is disclosed herein. The light system includes a housing with an inner shroud and an outer shroud, a first light source and a second light source. The inner shroud is disposed within the outer shroud, and both light sources are disposed within the inner shroud. The second light source may produce light and heat. The heat from the second light source may be absorbed by the first light source to enable the first light source to more efficiently produce light. The light system may provide light from both the first light source and the second light source simultaneously. The inner surface of the outer shroud may contain an infrared reflective coating configured to retain the heat produced from the second light source within the housing while still enabling the output of the visible light produced by the first and second light sources.

Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.

The chemical liquid storage includes a container and a chemical liquid, wherein the chemical liquid contains at least one of Fe, Al, Cr, and Ni, a content of the specific metal component in the chemical liquid with respect to a total mass of the chemical liquid is equal to or smaller than 100 mass ppt, at least a portion of a liquid contact portion of the container is formed of glass containing sodium atoms, and provided that B represents a content of sodium atoms in a bulk region with respect to a total mass of the bulk region, and A represents a content of sodium atoms in a surface region with respect to a total mass of the surface region, a content mass ratio of A to B represented by A/B is higher than 0.10 and less than 1.0 in at least a portion of the liquid contact portion.

A quartz glass crucible includes a crucible base body including silica glass and a coating film containing a crystallization accelerator and formed on the inner surface of the crucible base body. The average carbon concentration in the coating film, and the crucible base body within a range of 0 ?m or more and 300 ?m or less in depth from the inner surface of the crucible base body is 1.0?10.sup.12 atoms/cc or more and 3.0?10.sup.19 atoms/cc or less.

A quartz glass crucible includes a crucible base body having silica glass and a coating film containing a crystallization accelerator and formed on the inner surface of the crucible base body. The coating film has a peel strength of 0.3 kN/m or more.

A method of coating a substrate surface, the method comprising: providing a substrate having a surface, optionally, treating at least a portion of the substrate surface with an oxidising agent, treating at least a portion of the substrate surface with a composition comprising a polysaccharide, oligosaccharide, polyol or mixture thereof, and incubating the treated substrate with the composition for a predetermined time. Also disclosed are substrates comprising such a coating, vessels comprising such coated substrates and medicals devices comprising such substrates.

The present invention regards a method for internally coating a hollow glass body comprising the steps of: (a) applying on at least one internal surface of said hollow body at least one coating composition in form of liquid dispersion comprising at least one glass frit and at least one polymeric dispersing agent; (b) subjecting said internal surface comprising said coating composition to a thermal treatment, so as to obtain a vitrified coating layer.

A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.

The present disclosure relates to coated substrates, capillaries and microfluidic channels which exhibit an extended shelf life compared to uncoated substrates. More specifically the disclosure relates to charged coatings at physiological pH which may prolong the shelf life of the substrate, capillary or microfluidic channel before being applied to biological fluids. Said shelf life is measured by the ability to provide a low fluid contact angle after an extended storage interval in ambient atmospheric conditions.
