The chemical composition and protein quality of two varieties of buckwheat were measured and compared with the values of wheat. The protein quality was based on amino acid composition and true protein digestibility, biological value, net protein utilization, and utilizable protein obtained in N-balance experiments with rats. The protein content in buckwheat was approximately 12% and thus very
Chemical conversion synthesis of magnetic Fe1xCox alloy Chemical conversion provides a versatile platform for the synthesis of advanced nanomaterials with targeted phase, composition, and architecture. Here, we report a trioctylphosphine (TOP)-driven chemical conversion route to transform lamellar Fe1xCoxS1.2DETA (x = 0.1, 0.3, 0.5, 0.7, DETA =
EN 10318 - European StandardsThe alloying elements considered are aluminium, nickel, silicon and lead. This method is applicable to zinc contents between 40 % (m/m) and 100 % (m/m); aluminium contents between 0,01 % (m/m) and 60 % (m/m); nickel contents between 0,01 % (m/m) and 15 % (m/m); silicon contents between 0,01 % (m/m) and 3 % (m/m); lead contents between 0,005 % (m/m) and 0,1 % (m/m).
The crystalline phase was primarily native cellulose (75% to 85%) with a minor amount of cellulose nitrate (15% to 25%). Elemental analyses of acid digests of CI materials indicated that the major components (>0.1% by weight) included aluminum, boron, calcium, sodium, and sulfur. An acid-insoluble residue present in all four materials (3% to 5% of original sample weight) was found to consist primarily of aluminum silicate hydroxide
