摘要:A process is incorporated herein for the synthesis of bio-1,2-alkanediols, comprising: providing a bio-alkene having a carbon chain of about 5 to about 20 carbon atoms and a bio-1-alkene regioselectivity of at least about 80%, at least about 92% and/or at least about 95%; and converting the bio-alkene to a bio-1,2-alkanediol having a carbon chain length of about 5 to about 20 carbon atoms. Methods for treating catalysts which may be incorporated in the process for the synthesis of bio-1,2-alkanediols are also included herein. Such bio-1,2-alkanediols are used in compositions and products alone as antimicrobial materials, or with existing bio-compounds and/or antimicrobials, preservatives, alternative preservation systems and/or hurdle technology components. The bio-1,2-alkanediols incorporate a natural and bio-based pathway for antimicrobial effects in various compositions such as cosmetic, pharmaceutical, industrial and household products.

标题:Method for preparing carbon nanotube fibers with improved spinning properties using surfactant

摘要:The present invention provides a method for preparing carbon nanotube fibers with improved spinning properties using a surfactant and carbon nanotube fibers prepared by the method. According to the method for preparing carbon nanotube fibers of the present invention, the addition of a surfactant during the preparation of carbon nanotubes interrupts and delays the agglomeration of catalyst particles, which reduces the size of the catalyst particles and uniformly disperses the catalyst particles that play a key role in the formation of carbon nanotube fibers, thus increasing the strength and conductivity of carbon nanotube fibers and improving the spinning properties. While convention methods prepare carbon nanotube fibers by injecting a catalytic material for the synthesis of carbon nanotubes in a high-pressure supercritical state to be uniformly dispersed, the present invention uses a dispersant and thus does not require the injection in a high-pressure supercritical state.

摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.

标 题:Magnetic porous silica microparticles and synthesis method
发明人：GIORDANO RAQUEL DE LIMA CAMARGO; MOREIRA FERNANDO MANUEL ARAUJO; KOPP WILLIAN
权利人:FUNDAÇ O UNIVERSIDADE FED DE S O CARLOS
摘要:The present invention relates to magnetic porous silica microparticles with a surface area between 30 and 500 m 2 /g, a pore diameter between 2 and 200 nm, saturation magnetisation at room temperature between 20 and 75 emu/g and particle size between 1 and 300 μm, useful for the purification of biological products, chemicals, enzyme immobilisation and effluent treatment. The method for synthetizing such particles consists in the addition of an emulsion of ammonium sulphate, apolar solvent and surfactant to an emulsion of superparamagnetic nanoparticles, sodium silicate, apolar solvent and surfactant.
