The present disclosure provides, in part, a solvent compound for use as a slow evaporating replacement. More specifically, the present disclosure relates to VOC-exempt solvent compounds that may be used as a slow evaporating replacement.

Provided herein is a cleaning composition including: from 20 to 90% by weight of dimethyl sulfoxide, from 5 to 30% by weight of at least one mineral oil (M), and from 5 to 50% by weight of at least one bipolar organic solvent (L). The ranges of proportions indicated are in each case based on the total weight of the cleaning composition. Also provided herein is a method of cleaning components by employing the cleaning composition, and also the cleaned components themselves.

The disclosure further relates to a decontamination method using the gel.

A composition for paint removal and methods of making and of using the composition are provided. The composition comprises tetrahydrofuran (THF), an amine with a molar volume of <100 cm.sup.3/mol, and a solvent.

Disclosed herein are a solvent composition and methods of using the solvent composition. The solvent composition includes at least 80 wt. % of trans-1,2-dichloroetheylene (t-DCE), and 0.1 to 20 wt. % of at least one organic compound. The organic compound may be a hydrocarbon and/or an oxygenated solvent. The solvent composition may be used to clean a surface by contacting the surface with the composition to dissolve a contaminant on the surface. The composition may be used to remove a coating from a surface of a substrate by contacting the surface with the solvent composition to dissolve the coating and removing the composition containing the coating from the surface. The composition may also be used to deposit material on a substrate by dissolving the material in the solvent composition, applying the composition containing the material onto the substrate, and evaporating the composition from the substrate.

Embodiments herein relate to methods and systems for applying a transfer material layer to graphene during a graphene fabrication process. In an embodiment, a method of producing a graphene sensor element is included. The method includes forming a graphene layer on a growth substrate and applying a fluoropolymer coating layer over the graphene layer. The method includes removing the growth substrate and transferring the graphene and fluoropolymer coating layers onto a transfer substrate, where the graphene layer is disposed on the transfer substrate and the fluoropolymer layer is disposed on the graphene layer. The method also includes removing the fluoropolymer coating layer. Other embodiments are also included herein.

A coated, highly transparent film based on cellulose triacetate, is proposed that includes a) a support film acting as support layer and a cellulose triacetate or a mixture of cellulose esters and cellulose triacetate as main component, the cellulose triacetate or mixture being defined by a haze value of <0.5%, measured on the cellulose triacetate or mixture drawn out to a film after having been dissolved in dichloromethane or acetone, and b) a multi-functional coating applied in a coating solution to one or both sides of the support film. A dissolver medium can also be used as an enclosure medium. The highly transparent films of the invention can be used as window film, sunglasses film, laminating film, furniture foil, enclosing film, slide film for microscopy, cover slip replacement film and/or protective film, adhesive to glass, wood, metal, ceramic, cellulose derivative films or plastics following incipient dissolution or heat treatment.

The present disclosure provides a composition for cleaning or stripping a material from a substrate. The composition includes a primary solvent and a co-solvent. The co-solvent includes one or more caprolactam-derived solvents.

A composition includes a first solvent selected from methyl acetate, dimethyl carbonate, acetone, or a combination thereof, a second solvent selected from thiophene, 1,3-dioxolane, thioacetic acid, or a combination thereof, and, optionally, a third solvent selected from dimethyl sulfoxide, methyl glyoxal, propylene carbonate, gamma butyrolactone, ethylene carbonate, 2-chloro-1-propanol, methanol, ethanol, ethylene glycol, propylene glycol, 1-propanol, 2-propanol, or a combination thereof. The respective amounts of each solvent are further described herein, and the total amounts of the first solvent, the second solvent, and the third solvent sum to at least 90 volume percent of the total volume of the composition. The composition can be particularly useful for removal of a coating from a surface. Accordingly, a method of removing a coating from a surface is also disclosed.

Disclosed herein are a solvent composition and methods of using the solvent composition. The solvent composition includes at least 80 wt. % of trans-1,2-dichloroetheylene (t-DCE), and 0.1 to 20 wt. % of at least one organic compound. The organic compound may be a hydrocarbon and/or an oxygenated solvent. The solvent composition may be used to clean a surface by contacting the surface with the composition to dissolve a contaminant on the surface. The composition may be used to remove a coating from a surface of a substrate by contacting the surface with the solvent composition to dissolve the coating and removing the composition containing the coating from the surface. The composition may also be used to deposit material on a substrate by dissolving the material in the solvent composition, applying the composition containing the material onto the substrate, and evaporating the composition from the substrate.
