标题:由柠檬酸制成的可再生且可水降解的聚酰亚胺酯
摘要:柠檬酸是一种丰富的天然小分子,与伯胺缩合时可形成环状酰亚胺.柠檬酸的还原衍生物和甘氨酸的反应产生环状酰亚胺二酸.该单体与多种直链二醇和糖衍生二醇共聚,产生玻璃化转变温度可调的共聚物,范围为t G = 25 至 134 oc.与大多数聚酯不同,这些聚酰亚胺酯在环境相关条件下水解,因此有望成为高tg商品塑料的可持续替代品.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M
权利人:EXXONMOBIL RES & ENG CO
摘要:Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.

发明人：TALEBIESFANDARANI MAJID; MEHTA SEAN
权利人:NANO ONE MAT CORP
摘要:An improved process for forming a lithium metal phosphate cathode material, a precursor to the cathode material and a battery comprising the cathode material is described. The process comprising:n forming an first aqueous solution comprising a first molar concentration of Li+and a second molar concentration of PO 4 3− ; forming a second aqueous solution comprising organic acid or a salt of an organic acid and a metal selected from the group consisting of Fe, Ni, Mn and Co wherein said metal is present in a third molar concentration; allowing a precipitate to form; drying the precipitate; and calcining the precipitate thereby forming the lithium metal phosphate cathode material having a formula represented by LiMPO 4 /C wherein the lithium metal phosphate cathode material comprises up to 3 wt % carbon.

标 题:Synthesis of environmentally degradable alkyl polyesters
发明人：PARK KINAM; GARNER JOHN SOLOMON
权利人:AKINA INC
摘要:A solid crosslinked polyester composition that is environmentally degradable in less than about 180 days. The crosslinked polyester can be the polyesterification reaction product between one or more multi-hydroxylic alcohols, one or more hydroxy acids, and one or more multi-carboxylic acid compounds. Alternately, the crosslinked polyester can be the polyesterification reaction product of one or more multi-hydroxylic alcohols, one or more hydroxy acids, one or more multi-carboxylic acid compounds, and a cyclic ester. Provided, however that if the one or more hydroxy acids has only one carboxyl group, it has two or more hydroxyl groups, and if the one or more hydroxy acids has only one hydroxyl group, it has two or more carboxyl groups.
