The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.

Sugar solutions are obtained from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction. The solid fraction is separated from the lignin-containing liquid fraction and contacted with an acid solution, the acid solution comprising about 70 weight percent to about 100 weight percent sulfuric acid or an acid mixture comprising phosphoric acid and sulfuric acid, at a temperature and for a reaction time sufficient to produce a decrystallized biomass mixture. Water is added and the diluted biomass mixture is then hydrolyzed to produce a saccharification product comprising sugars.
