标题 :Direct synthesis of alkenylhalosilanes
发明人：LEWIS KENRICK MARTIN; ZHU YANJUN; BYRNE CHRISTOPHER M
权利人:MOMENTIVE PERFORMANCE MAT INC
摘要:A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

权利人:BAYER IP GMBH; BAYER SOUTH EAST ASIA PTE LTD
摘要:The present invention relates to a method for the synthesis of semiconductor nanoparticles comprising elements of the groups IB, IIB, IIIA, IVA, VA or VIA of the periodic classification wherein the composition of the core nanoparticle is selected from the group consisting of IB-VIA, IIB-VIA, IIIA-VIA, IB-IIIA-VIA or IB-IIB-TVA-VIA, IIB-IIIA-VIA, IIB-TVA-VA or mixtures thereof, and at least one shell comprises elements of the groups IIB and VIA,, wherein in case the core composition is IIB-VIA the shell comprises at least a further element selected from the groups IB, IIIA, IVA or VA, using metal precursors comprising non- or weakly coordinating anions. It further relates to the consecutive process for the synthesis that includes first the preparation of a binary nanoparticle system then modified to make a ternary system which again can be further modified to make a quaternary system.

权利人:DAL FARRA CLAUDE; DOMLOGE NOUHA; BOTTO JEAN-MARIE; ISP INVESTMENTS INC
摘要:The present invention concerns a peptide of the general formula (I): n R 1 -(AA) n -X 1 —X 2 —X 3 -Pro-X 4 —X 5 —X 7 -(AA) p -R 2 , capable of activating the synthesis of proteins of the family of aquaporins. n The present invention also concerns a cosmetic, nutraceutical or pharmaceutical composition, comprising a peptide of general formula (I) as active principle. The invention also relates to the use of this new active principle in a cosmetic or nutraceutical composition, intended to improve the moisturizing and the barrier function of the epidermis and intended to stimulate cutaneous regeneration. The invention also relates to the use of this new active principle to realize a pharmaceutical composition, and in particular a dermatological composition, intended to regulate and/or stimulate the activity of the aquaporins and to thus treat the pathological dryness of the skin or mucosa. The invention also relates to a method of cosmetic treatment intended to prevent or combat against dryness of the skin and mucosa, and the manifestations of cutaneous ageing.
