摘要： The present invention relates to novel alkylhalosilylaminoboranes, in particular alkylchlorosilylaminoboranes, which make it possible to adjust the viscosity of polyborosilazane compounds by varying the number of reactive centers, to novel borosilazane compounds, to novel oligoborosilazane or polyborosilazane compounds which have the structural feature R1—Si—NH—B—R2, where R1 or R2 or both is/are a hydrocarbon radical having from 1 to 20 carbon atoms, in particular an alkyl, phenyl or vinyl group, to silicon borocarbonitride ceramic powder, to ceramic material based on SiC, SiN and BN and to processes for producing each of these and to the use of the polyborosilazanes and the ceramic materials.

摘要： The invention relates to a method for controlling the alertness of a human subject and a light source for use in this method and use of a light source for this method. The method comprises exposure of a human subject during an exposure period to suitable light radiation without substantially influencing the phase of a melatonin cycle. Melatonin is a sleep-hormone that can be used to control the alertness of a human subject The suitable light radiation being specified by an output fraction of melatonin suppressive radiation (Melatonin Watt/Watt) and light output (lumen/Watt), the output fraction and light output being adjusted to obtain the desired effect on the phase of said cycle.

摘要： The present invention pertains to a method for producing a polysilane-polycarbosilane copolymer solution, which comprises the preparation of a polysilane, obtained by the disproportionation of a methylchlorodisilane or a mixture of methylchlorodisilanes of the formula Si2MenCl6-n with a Lewis base as the catalyst, a subsequent thermal crosslinking of the polysilane to form an infusible polysilane-polycarbosilane copolymer that is soluble in inert solvents, as well as the production of said solution by the dissolution of the polysilane-polycarbosilane copolymer in an inert solvent. In addition, the present invention also pertains to a method for producing oxygen-depleted ceramic fibers and other molded bodies having a composition similar to that of SiC. The method for producing the fibers comprises the preparation of a polysilane-polycarbosilane copolymer solution, the spinning of this solution to obtain green fibers according to the dry spinning method, as well as the pyrolysis of the dried green fibers under an inert gas atmosphere or a reducing atmosphere.
