20120122669 | METHOD OF ARRAYING FERRITIN - A method of selectively arraying ferritin and inorganic particles on a silicon oxide substrate having a chromium, niobium or tungsten portion. An aspect of the method includes steps of: preparing a solution which contains ferritin modified at an N-terminal part of a subunit with a peptide set out in SEQ ID NO: 1, and a nonionic surfactant; and a binding step of bringing the solution in contact with the silicon oxide substrate to selectively array peptide-modified ferritin to the chromium, niobium or, tungsten portion. Another aspect of the method includes selectively arraying ferritin modified with the peptide set out in SEQ ID NO: 1, and the inorganic particles contained in ferritin at the chromium, niobium, or tungsten portion by removing the solution. | 05-17-2012 |
20140302982 | CATALYTIC CONVERSION OF CARBOHYDRATES INTO 5-HYDROXYMETHYLFURFURAL - The present invention relates to catalysts and methods for efficient conversion of carbohydrates into 5-hydroxymethylfurfural (HMF), which shows good activity and high selectivity for HMF preparation from saccharides. The catalyst is stable in aqueous system which makes it as an ideal catalyst for HMF production. High HMF yield was obtained even in mild condition. The catalysts of the invention are advantageous in that they are environment-friendly, easy separation and recovery, can be re-used in subsequent reactions, do not corrode reaction reactors. These features make the catalyst as a suitable catalyst for HMF preparation and have strong industrial application significance. | 10-09-2014 |

20120258855 | PROCESS FOR MANUFACTURING A CATALYST SUPPORT AND A CATALYST - The invention relates to a process for manufacturing a catalyst support, in which one or more fibres are fed into a mould, said fibre having a diameter in the range of 5-300 microns, and a length over diameter ratio greater than 500. The body in the mould is compressed and then contacted with a mixture comprising a liquid and a carrier material. The liquid is removed from the wetted body to provide a catalyst support comprising an entangled fibre and carrier material. A catalyst can be made using the same process and additionally adding a catalytically active metal with the mixture comprising a liquid and a carrier material. Alternatively a catalyst can be made using the process for manufacturing a catalyst support followed by impregnation with a catalytically active metal. | 10-11-2012 |
