Abstract: A method to facilitate the reduction of solar radiation impacting Earth proposes the use of a plurality of porous particles that are introduced into Earth's stratosphere at an average distance of at least 10 kilometers above sea level. Each porous particle has a continuous polymeric phase composed of an organic polymer, and discrete pores dispersed within the continuous polymeric phase. Each porous particle has a mode particle size of 2-20 μm; a coefficient of variance (CV) of no more than 20% compared to the mode particle size; and a porosity of 20%-75%. The discrete pores have an average pore size “d” (nm) that is defined by 0.3≤d/λ≤0.8 wherein λ is 400-3,000 nm. Each of the discrete pores of the porous particles is filled with air and optionally a pore stabilizing hydrocolloid that is disposed at the interface of the discrete pore and the continuous polymeric phase.

Abstract: Composites of metal-organic framework particles and bacterial cellulose, methods of making the composites, and methods of using the composites in the hydrolysis of organic compounds are provided. The composites, which are aerogels comprising metal-organic framework particles embedded in a bacterial cellulose nanofiber network, are fabricated using a microbial synthesis strategy in which bacterial cellulose nanofiber is biosynthesized using a cellulose-producing bacteria in a fermentation medium in which metal-organic framework particles are dispersed.

Abstract: A composition comprising nanocellulose is disclosed, wherein the nanocellulose contains very low or essentially no sulfur content. The nanocellulose may be in the form of cellulose nanocrystals, cellulose nanofibrils, or both. The nanocellulose is characterized by a crystallinity of at least 80%, an onset of thermal decomposition of 300° F. or higher, and a low light transmittance over the range 400-700 nm. Other variations provide a composition comprising lignin-coated hydrophobic nanocellulose, wherein the nanocellulose contains very low or essentially no sulfur content. Some variations provide a composition comprising nanocellulose, wherein the nanocellulose contains about 0.1 wt % equivalent sulfur content, or less, as SO4 groups chemically or physically bound to the nanocellulose. In some embodiments, the nanocellulose contains essentially no hydrogen atoms (apart from hydrogen structurally contained in nanocellulose itself) bound to the nanocellulose. Various compositions, materials, and products may incorporate the nanocellulose compositions disclosed herein.

Abstract: A method for preparing cellulose dope from textile waste including cellulose fibers in a mass percentage of more than 50%. The method includes shredding the textile waste in order to obtain a first mixture of shredded fibers and residues, separating at least a portion of the non-cellulosic components from the first mixture in order to obtain a second mixture in which the mass percentage of cellulose fibers is greater than the mass percentage of cellulose fibers in the first mixture, filtering the second mixture in order to recover a solid phase including the cellulose fibers, dissolving the cellulose fibers of the solid phase so as to obtain a cellulose dope including undissolved particles, and filtering the cellulose dope in order to obtain a cellulose dope that is separated from the undissolved particles.

Abstract: Compositions include a plurality of polymer particulates comprising a matrix polymer and one or more types of nanoparticles selected from the group consisting of biopolymer nanoparticles, biomineral nanoparticles excluding biomineralized silica alone, and any combination thereof. Illustrative examples of such nanoparticles may include cellulose nanoparticles, hydroxyapatite nanoparticles, or any combination thereof associated with the matrix polymer. The polymer particulates may be prepared by melt emulsification. Methods include depositing such polymer particulates in a powder bed; and heating a portion of the powder bed to consolidate a portion of the polymer particulates into a consolidated part having a specified shape. The matrix polymer may be biodegradable and lose at least about 40% mass in six days in a phosphate buffer solution (0.2 M, pH 7.0) containing 0.2 mg/mL of lipase obtained from Pseudomonas cepacia (≥30 U/mg) and incubated at 37° C.
