The vesicles are shown to be effective as delivery agents for chemical and biological agents. They are also shown to be useful in methods of treatment and as components of an immunogenic composition.
专利号:US-2022355262-A1 优先权日:2019-07-22 标题 :System and method for manufacturing water-based hydrophobic aerogels and aerogel composites 发明人:SACHITHANADAM MAHESH; KHORASGANI SOGHRATI ELMIRA; NATARAJAN GAYATHRI 权利人:KROSSLINKER PTE LTD 摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.

专利号:WO-2024074396-A1 优先权日:2022-10-03 标题 :Process for the production of catalyst for polyolefin synthesis 发明人:ZHU YIZU; ALLADA RAMA KUMAR; BAI HUA; DESHPANDE HAREESH SHAMRAO; GUNASEKARAN SIVALINGAM; PANITZKY JENS; SHAFIEI MOHAMMAD; VADAKE KULANGARA SHANEESH; Jian Hongbing 权利人:SABIC GLOBAL TECHNOLOGIES BV 摘要:The invention relates to a process involving the steps of: (a) supplying reactants to a reactor vessel (A); (b) optionally, supplying a solvent to the reactor vessel; (c) subjecting the contents of the reactor vessel to reactive conditions to obtain a product mixture (1) comprising a reaction product; (d) removing the product mixture (1) from the reactor vessel and supplying it to a decanter system (B); (e) in the decanter system, separating the reaction product from the product mixture by decantation and removal of a stream (2) comprising the reaction product; (f) removal of a stream (3) comprising the solvent from the decanter system; wherein at least one of the reactants supplied in step (a) is supplied in a form dissolved in a solvent, or a solvent is supplied in step (b). Such process allows for the production of a catalyst system having a low average particle size, such as 2-4 µm, having a high purity, at high procedural efficiency.
