Accordingly, the present invention provides proteins involved in iron transport and/or metabolism and polynucleotides encoding those proteins. The present invention also provides expression cassettes containing the polynucleotides. The present invention also provides cells containing the expression cassettes, polypeptides, and/or polynucleotides of the invention.
Abstract:
Disclosed are foam compositions and processes to form closed-cell tannin-based foams. The process comprises forming an agglomerate-free solution comprising a tannin, a first monomer, a second monomer, and water, wherein the first monomer comprises formaldehyde, paraformaldehyde, furfural, glyoxal, acetaldehyde, 5-hydroxymethylfurfural, acroleim, levulinate esters, sugars, 2,5-furandicarboxylic acid, 2,5-furandicarboxylic aldehyde, urea, difurfural (DFF), or mixtures thereof, and the second monomer comprises furfuryl alcohol, glycerol, sorbitol, lignin, or mixtures thereof. The process also comprises mixing one or more blowing agents with the agglomerate-free solution to form a pre-foam mixture and mixing an acid catalyst with the pre-foam mixture to form a foam composition. The process comprises adding a surfactant to at least one of the agglomerate-free solution, pre-foam mixture, or the foam composition. The process further comprises processing the foam composition to form a tannin-based foam.

The foams comprises a continuous polymeric phase defining a plurality of cells, wherein the continuous polymeric phase comprises a phenol-formaldehyde resole derived from a phenol and formaldehyde, and wherein the plurality of cells comprises a plurality of open-cells and a plurality of closed-cells with an open-cell content measured according to ASTM D6226-5, of less than 50%. The foam composition also comprises a discontinuous phase disposed in at least a portion of the plurality of closed-cells, the discontinuous phase comprising 1,1,1,4,4,4-hexafluoro-2-butene
Abstract:
The present invention relates to a porous adaptive membrane structure that has movable membranes. The structure can be made to change its gas, liquid or particulate permeability in response to surrounding environmental conditions. The application of this invention is includes protective apparel that is comfortable to wear wherein the level of protection provided is based on conditions in the environment. Hence, the protective apparel is highly breathable and comfortable in a non-hazardous environment but impermeable or only semipermeable in a hazardous environment.
