Abstract: Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, plasticizers, with the addition of a diacid, diglycidyl ether, silicone and/or a glyceride additive added during gelatinization of the starch and plasticizer, before blending of such starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, polyamides, etc.). Silicones, where added, may alternatively be added after formation of the thermoplastic starch, e.g., as part of a masterbatch, when blending with another polymer. Addition of silicone reduces glycerin migration and smoke generation, particularly when processing such compositions to form nonwovens. Addition of glycerides (e.g., triglycerides) can increase hydrophobicity of the resulting starch-based polymeric material.

Abstract: Thermoplastic starch-based materials formed as a reactive extrusion product from one or more starches, one or more plasticizers, and micro or nano particles or fibers, with such particles or fibers being added before gelatinization of the starch. A diacid or acid anhydride may also be included. Such components are added and then gelatinized together, before blending of a resulting starch-based polymeric material with any other polymer (e.g., polyester biopolymers, polyolefins, or the like). Addition of such nano or micro particles during synthesis of the thermoplastic starch advantageously results in a far more homogenous distribution of such particles or fibers throughout the starch-based material matrix than occurs where addition of similar particles or fibers is attempted after formation of the thermoplastic starch, e.g., when mixing with a partner resin material. Addition of a diacid during synthesis can reduce molecular weight and viscosity, further aiding in achieving substantially uniform distribution.

Abstract: This disclosure relates to weldability of steel alloys that provide weld joints which retain hardness values in a heat affected zone adjacent to a fusion zone and which also have improved resistance to liquid metal embrittlement due to the presence of zinc coatings.

Abstract: This invention is related to retention of mechanical properties in high strength steel at reduced thicknesses and which mechanical property performance is also retained at relatively high strain rates. These new steels can offer advantages for a myriad of applications where reduced sheet thickness is desirable. In addition, the alloys herein are those that retain useful mechanical properties after introduction of a geometric discontinuity and an accompanying stress concentration.

Abstract: This disclosure is related to high yield strength steel where yield strength can be increased without significantly affecting ultimate tensile strength (UTS) and in some cases, higher yield strength can be obtained without significant decrease in ultimate tensile strength and total elongation.
