Abstract: The invention relates to an aqueous suspension formulation for aerosol formation, said suspension formulation comprising lipid or lipidoid nanoparticles which are suspended in an aqueous vehicle solution, wherein the lipid or lipidoid nanoparticles comprise the following components (a) and (b): (a) a nucleic acid and (b) an ionizable lipid or an ionizable lipidoid; and wherein the aqueous vehicle solution comprises a triblock copolymer which contains one poly(propylene oxide) block and two poly(ethylene oxide) blocks. Moreover, the invention relates to an aerosol obtained from the formulation for aerosol formation.

Abstract: Provided is a composition comprising (i) a nano- or microparticle formulation of a therapeutically active agent which is suspended in a liquid phase, and (ii) at least one cryoprotective additive selected from C3-C5 alkanes substituted by one or two hydroxy groups which stabilizes the particle formulation. Further aspects relate to a solid composition which can be obtained by freezing the stabilized composition, and to processes for the preparation of the compositions in accordance with the invention.

Abstract: A system and method for inspecting a part to be monitored that is arranged inside a mechanical member, said part to be monitored including a plane wall and a curved wall presenting an angle between them. The system comprises a probe endoscope (20) carrying a head (30), said head (30) presenting a plane face (31) that is suitable for being pressed against said plane wall, said head (30) having an ultrasound probe (35) and at least one magnet (36) flush with said plane face (31), said head (30) having a curved face (32) that is perpendicular to the plane face (31) and that matches the shape of the curved wall of the part to be monitored, the plane face (31) and the curved face (32) forming an L-shaped structure that is suitable for being held against the part to be monitored via each magnet (36), while allowing said part to be monitored to rotate relative to said head (30).

Abstract: Silicate catalysts which can be employed for selective oxidation reactions of organic substances, a process for the preparation of these catalysts and their use are described.The catalyst is distinguished by high long-term activity, by the reaction temperature required for the reaction being lower in comparison with catalysts composed of pure silver and by higher conversions and selectivities in the oxidative dehydrogenation of alkanols in comparison with pure silver or silver on supports.

Abstract: A process for the preparation of carbonyl compounds by the oxydehydrogenation of (C.sub.1 -C.sub.4)-alcohols is carried out at a temperature from 400.degree. to 700.degree. C. in the presence of a silicate catalyst which has been doped with silver and silver ions. By means of the process carried out at relatively low temperatures, for example, are that high yields are achieved, the content of carbon monoxide is low and the product gas contains, apart from carbon dioxide, no further determinable by-products and has a low water/formaldehyde ratio.

Abstract: The process dehydrogenates methanol in the presence of a catalyst based on aluminum oxide, alkali metal aluminate and/or alkaline earth metal aluminate with the exclusion of oxygen at a temperature of 650.degree. to 1050.degree. C. in a reactor whose inner wall is composed entirely or partly of aluminum oxide. The process gives anhydrous formaldehyde which contains only very minor impurities.
