A process for producing a thermoplastic material for use as powder or slurry for further processing such as injection molding or coating, comprising the steps of mixing a biomass containing prolamins, such as a grain source or a water insoluble fraction of a grain, having prolamins and lipids, and an organic solvent to obtain undissolved components and dissolved components comprising dissolved prolamin, lipids and other dissolved components, extracting the dissolved components into a first liquid and extracting undissolved components in a first solid under the specific conditions. separating the first solid from the first liquid, recovering the thermoplastic material from the first liquid as powder by removing organic solvent under the conditions of maintaining temperature of the prolamins below 80° C., preferably below 75° C., maintaining a dielectric constant εr between 30 and 42 at 25° C., and maintaining a pressure level at below 2 bar.

A coating, a method for coating surfaces, and the coated surfaces. The method includes providing a substrate with a cleaned metal surface; contacting and coating the metal surface with an aqueous composition having a ph of from 0.5 to 7.0 and in the form of a dispersion and/or a suspension; optionally rinsing the organic coating; and drying and/or baking the organic coating, or optionally drying the organic coating and coating same with a similar or another coating composition thereto. The composition contains a complex fluoride in a quantity of 1.1 10.sup.−6 mol/l to 0.30 mol/l based on the cations. An anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt % based on the total mass of the resulting mixture is added to an anionically stabilized dispersion made of film-forming polymers and/or a suspension made of film-forming inorganic particles.

A hydroxyl-covered silicon quantum dot nanoparticle having a silicon core, a plurality of silicon quantum dots, and a plurality of hydrocarbon chains is illustrated. A first portion of a surface associated with the silicon core is passivated by a plurality of silicon hydroxyl groups (Si—OH). The silicon quantum dots are attached to a second portion of the surface associated with the silicon core. The hydrocarbon chains are bonded to each of the silicon quantum dots through a plurality of silicon carbide bonds (Si—C), wherein each termination of the hydrocarbon chains has a carbon hydroxyl group (C—OH), such that the hydroxyl-covered silicon quantum dot nanoparticle is thoroughly covered by the carbon hydroxyl groups (C—OH) and the silicon hydroxyl groups (Si—OH).

The invention provides a method for the controlled assembly of layered silk fibroin coatings using aqueous silk fibroin material. The methods described herein can be used to coat substrates of any material, shape, or size. Importantly, the described methods enable control of the biomaterial surface chemistry, thickness, morphology and structure using layered thin film coatings, or bulk coatings. Furthermore, the methods can be performed in all water and do not require intensive chemical processing enabling controlled entrapment of labile molecules such as, drugs, cytokines, and even cells or viruses to generate functional coatings that can be used in a variety of applications.
