摘要:
Verfahren zur Rückgewinnung wenigstens eines SE-Metalls aus einem das wenigstens eine SE-Metall aufweisenden Substrat, wobei das Verfahren bevorzugterweise wenigstens die folgenden Schritte umfasst: (a) Bereitstellen des Substrats in einer beheizbaren Ladezone L1 bei einer Temperatur T 1 und einem Druck P 1 , (b) Bereitstellen wenigstens einer Abscheidungsvorrichtung in einer beheizbaren Abscheidezone L2 bei einer Temperatur T 2 und einem Druck P 2 , (c) Chemisches Transportieren des SE-Metalls und/oder einer das SE-Metall enthaltenden Verbindung, in einem Temperatur- und/oder Druckgradienten von der Ladezone L1 zur Abscheidezone L2, wobei T 2 > T 1 ist.
摘要:
The invention provides novel compositions comprising semifluorinated alkanes and at least one compound sensitive or prone to oxidation. The compositions can be used as medicines that are topically administered to an eye or ophthalmic tissue. The invention further provides kits comprising such compositions.
摘要:
The invention provides novel compositions of bioactive polypeptides and proteins with improved stability and shelf-life. The compositions are based on liquid vehicles selected from semifluorinated alkanes. These vehicles are remarkably effective in protecting polypeptides and proteins from degradation and/or aggregation. The compositions are useful for topical administration, e.g. into an eye, or by parenteral injection, e.g. via the subcutaneous or intramuscular route.
摘要:
A liquid eye wash composition for removing foreign agents from an eye or ophthalmic tissue is provided. The composition comprises one or more semifluorinated alkanes, and optionally further constituents. Further provided are methods of using the composition, either alone or in combination with other means of removing contaminants from an affected eye.
摘要:
The invention provides liquid compositions in the form of physically stable emulsions comprising a semifluorinated alkane. The semifluorinated alkane is comprised in the dispersed phase, which may also include an active pharmaceutical ingredient. One of the preferred active ingredients is propofol. The compositions are optionally heat sterilisable and can be used for pharmaceutical or cosmetic product applications, and administered topically, intravenously, or via other routes.
摘要:
A clean-in-place launching station with cleaning chamber (2) for cleaning a pipeline pig (16) is disclosed. The cleaning chamber (2) is equipped and configured to enable the pig to be completely surrounded by turbulently flowing cleaning fluid during the cleaning process. A plunger (3) capable of axially moving the pig (16) is completely encased within the cleaning chamber. The plunger (3) has at least one internal fluid channel (10) which connects the space in front of the front end (6) of the plunger facing the pig (16) with the space behind the back end (8) of the plunger.
摘要:
The present invention relates to novel pharmaceutical compositions in powder or granule form which comprise a low-dose drug attached to a water-soluble carrier, such as by adhesion or adsorption. The compositions further comprise an oily liquid which facilitates the attachment of the active ingredient to the carrier particles. Moreover, the invention provides methods for preparing such powders or granules, and compressed tablets incorporating them.
摘要:
The invention provides novel pharmaceutical compositions based on semifluorinated alkanes which are useful as carriers for a broad range of active ingredients. Preferred active ingredients include poorly water-soluble and/or hydrolytically sensitive drug substances. The compositions are designed as suspensions and have superior physical properties which make them highly useful as pharmaceutical delivery systems. The compositions may be administered topically into the eye, or injected via the subcutaneous or intramuscular route. The invention further provides kits comprising such compositions.
