摘要:The subject of the invention is anatase nanoparticles and ways of the synthesis thereof by a gel- sol method from sodium titanate, which is produced from metatitanic acid in a reaction with NaOH. The molar ratio between NaOH and TiO 2 must be low for a synthesis of sodium titanate, if the goal is to synthetize anatase, i. e. is between 1 :3 to 1 : 1. If the goal is to synthetize rutile, the molar ratio must be higher, at least between 3: 1 to 4: 1. In the gel-sol reaction between sodium titanate and acid very small anatase particles are formed that are of spherical morphology, polycrystalline and present in the acidic suspension. The size of crystallites that constitute the anatase particles is approximately 5 nm, wherein the particles themselves are bigger, somewhere between 40 to 60 nm. The subject of the invention is also a manner of stabilising the acidic suspension of nanoparticles, which allows an increase in pH value without causing excessive agglomeration, which is achieved by the use of an suitable dispersant, citric acid. A further subject of the invention is a hydrothermal method, which allows re-crystallisation of polycrystalline anatase nanoparticles into a monocrystalline form under hydrothermal conditions in an autoclave at a temperature about 130 °C or more and at adequate pressure of the water vapour.

摘要:A method for synthesizing a deuterated acrylate of the Formula (1), the method comprising: (i) deuterating a propiolate compound of Formula (2) to a methyne-deuterated propiolate compound of Formula (3) in the presence of a base and D 2 O: and (ii) reductively deuterating the methyne-deuterated propiolate compound of Formula (3) in a reaction solvent in the presence of deuterium gas and a palladium-containing catalyst to afford the deuterated acrylate of the Formula (1). The resulting deuterated acrylate compounds, derivatives thereof, and polymers derived therefrom are also described.

摘要:Topical compositions containing creatine and its precursors and derivatives, are used to improve skin condition and to treat or prevent skin disorders, abnormal lipid peroxidation, reduced cell-cell communication, deficient intracellular DNA synthesis, DNA damage, deficient DNA repair, abnormal post-translational modification of connective tissue components and dandruff. Topical compositions comprising creatine and its precursors and derivatives and optionally electrolytes, polyols, urea and osmolytes are used: (1) to treat or prevent dry skin, to enhance the barrier function of the skin, for treatment, care and prophylaxis of sensitive skin and/or for treatment and prophylaxis of symptoms of a negative change in the physiological homeostasis of normal skin; (2) to treat or prevent inflammatory skin conditions, atopic eczema, polymorphic photodermatitis, psoriasis, vitiligo and sensitive, itching or irritated skin; (3) to treat or prevent abnormal lipid peroxidation; (4) to treat or prevent abnormal ceramide, lipid and energy metabolism of the skin, abnormal transepidermal water loss, reduced skin hydration and moisture content and altered Natural Moisturizing Factor content; (5) to treat or prevent reduced cell-cell communication, deficient intracellular DNA synthesis, DNA damage, reduced endogenous DNA repair, activation of metalloproteinases and/or other proteases or inhibition of corresponding DNA repair mechanisms and abnormal post-translational modification of connective tissue components; (6) to treat or prevent abnormal skin hyaluronic acid and glucosaminoglycan content; and (7) to treat or prevent dandruff of the hair and scalp and skin aging.
