专利号:US-10669160-B2 优先权日:2018-04-30 标题:Heterogeneous wet synthesis process for preparation of high purity tungsten pentahalide 发明人:LIU YUMIN; LI FENG; WAN ZHIWEN; FAFARD CLAUDIA; WIESE STEFAN; HUSSON GUILLAUME; NIKIFOROV GRIGORY; SUI BIN; GIRARD JEAN-MARC 权利人:AIR LIQUIDE; AIR LIQUIDE AMERICAN 摘要:Synthesis of tungsten pentahalide compositions having low impurity profiles are disclosed. The specific impurity profile permits deposition of high purity tungsten-containing films using vapor deposition processes or other semiconductor manufacturing processes without introduction of performance-impacting contaminants.
专利号:US-10799441-B2 优先权日:2011-06-06 标题:Skin treatments containing pyrroloquinoline quinone (PQQ) esters and methods of preparation and use thereof 发明人:LEWIS II JOSEPH ABERNATHY; DINARDO JOSEPH C 权利人:LEWIS II JOSEPH ABERNATHY; DINARDO JOSEPH C; PCR TECH HOLDINGS LC 摘要:The present invention relates to cosmetic or dermatological compositions containing PQQ or its esters, methods of treating or promoting skin changes by topical application of these compositions, and methods of synthesis of PQQ esters. The PQQ ester-containing compositions of the present invention are unexpectedly effective in treating skin, particularly with respect to skin tolerance. When included in a topical composition, the PQQ esters of the present invention have an antioxidant effect that is useful in treating a skin change.
