摘要:The present invention discloses a novel cost effective method for synthesis of protein/peptide amphiphiles irrespective of functional and structural classification of proteins useful in designing a vaccine candidate from antigenic protein. The protein modification of the present invention is universal and hence any protein/peptide can be converted into amphiphilic proteins/peptides.

摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

摘要:PCT No. PCT/FR90/00599 Sec. 371 Date May 10, 1991 Sec. 102(e) Date May 10, 1991 PCT Filed Sep. 11, 1990 PCT Pub. No. WO91/04226 PCT Pub. Date Apr. 4, 1991.An aluminosilicate gel containing an ST structuring agent whose composition is suitable for crystallization into a zeolite of the faujasite structural family is prepared. The gel then undergoes crystallization in order to form a zeolite precursor which consists of the zeolite containing the ST structuring agent in its cavities and channels, the zeolite being produced through the calcination of the precursor. The ST structuring agent consists of at least one compound from the alkylene polyoxides of formula (1) (I) in which R and R', identical or different, each represents H or an alkyl radical in C1 to C4, X designates H or OH, m is equal to 2 or 3 and can differ from one pattern to another, and n is a number from 1 to 12. The zeolites thus obtained have a Si:Al ratio which is greater than 1 and which can go beyond 3, and show a cubic symmetry. The zeolites can be used, directly or after cation exchange, as adsorbants or as catalyst constituents.

权利人:ELF AQUITAINE
摘要:A process is provided for the preparation of zeolites belonging to the faujasite structural class and exhibiting a Si:Al ratio higher than 1 in which a reaction mixture is first produced, which has a pH higher than 10 and contains water, a source of tetravalent silicon, a source of trivalent aluminum, a source of hydroxide ions in the form of a strong inorganic or organic base and a structuring agent ST so as to produce an aluminosilicate gel having the desired composition to permit its crystallization into a compound of the faujasite structural class. The gel obtained is kept at a temperature, pressure and for a sufficient period to effect the crystallization of the gel into a precursor of the zeolite consisting of the zeolite trapping the structuring agent ST in its cavities and the precursor is then subjected to a calcination to destroy the structuring agent and to produce the zeolite. The structuring agent ST consists of at least one compound belonging to the group formed by the carbon-containing macrorings and macropolyrings which contain in the rings heteroatoms chosen from oxygen, nitrogen, silicon and sulphur, and which contain 10 to 24 atoms per ring. Precursors of the zeolites are also provided.
