标题:Synthesis of semi-crystalline polyphthalamides through reactive extrusion of hexamethylene terephthalamide oligomer with lower melting, semi-crystalline or amorphous polyamides

权利人:LEBOEUF CHRISTIAN; HARBOURNE DAVID ALAN
摘要:This invention relates to the synthesis of semi-crystalline polyphthalamides (i.e. containing monomeric units of terephthalic acid and hexamethylene diamine) through reactive extrusion of hexamethylene terephthalamide oligomer, or the oligomer of another 6T-rich copolymer, with lower melting semi-crystalline or amorphous polyamides. This process is particularly useful since it is centered around the use of stirred autoclaves for the synthesis of the 6T oligomer and the semi-crystalline or amorphous polyamides which are subsequently combined in a twin screw extruder equipped for devolatilization of water of reaction. It can also be used for the modification of existing semi-crystalline or amorphous polyamides (not necessarily phthalamides) with low levels of 6T.

标 题:Synthesis of quantum dots
发明人：MCDANIEL HUNTER
权利人:LOS ALAMOS NAT SECURITY LLC
摘要:Common approaches to synthesizing alloyed quantum dots employ high-cost, air-sensitive phosphine complexes as the selenium precursor. Disclosed quantum dot synthesis embodiments avoid these hazardous and air-sensitive selenium precursors. Certain embodiments utilize a combination comprising a thiol and an amine that together reduce and complex the elemental selenium to form a highly reactive selenium precursor at room temperature. The same combination of thiol and amine acts as the reaction solvent, stabilizing ligand, and sulfur source in the synthesis of quantum dot cores. A non-injection approach may also be used. The optical properties of the quantum dots synthesized by this new approach can be finely tuned for a variety of applications by controlling size and/or composition of size and composition. Further, using the same approach, a shell can be grown around a quantum dot core that improves stability, luminescence efficiency, and may reduce toxicity.

摘要:The invention is directed to a method of synthesizing aluminophosphate or silicoaluminophosphate molecular sieves and in particular to the synthesis of silicoaluminophosphate molecular sieves using synthesis templates in combination with a source of fluoride comprising at least two fluoride substituents. The use of such fluorine containing compounds results in good quality low silica SAPO molecular sieves of CHA framework type.
