Preparation of Porous Carbon by Pyrolysis of Silylated Graphite Oxide
Starting from the graphite oxide silylated by 3-aminopropylmethyldiethoxysilane, porous carbons containing silica with layered structure were obtained. They possessed both microporosities and mesoporosities existing most likely between the carbon layers and the BET surface area reached 226 m/g. These types of carbons were obtained only when the silicon content in the initial silylated graphite ...
متن کاملNew Stellar Sources for High-density, Presolar Graphite Grains
We present C, N, O, Si, Al-Mg, K, Ca, and Ti isotopic analyses of seven high-density (ORG1f, 2:02 2:04 g cm ) graphite grains from Orgueil with C/C ratios smaller than 20. The presence of 44Ti in three of these grains indicates an origin in Type II supernovae (SNe). The C excesses in these SNe grains, however, remain enigmatic. The remaining grains have extremely large Ca and Ti isotopic anomal...
متن کاملProkaryotic RNA preparation methods useful for high density array analysis: comparison of two approaches.
High density oligonucleotide arrays have been used extensively for expression studies of eukaryotic organisms. We have designed a prokaryotic high density oligonucleotide array using the complete Escherichia coli genome sequence to monitor expression levels of all genes and intergenic regions in the genome. Because previously described methods for preparing labeled target nucleic acids are not ...
متن کاملEffect of Different CNT’s Oxidation Methods on Thiocoline Detection by Surfactant Modified Graphite Electrodes
Carbon nanotubes are regarded as promising building blocks for the construction of novel biosensors due to their unique properties like fast electron transfer, high electrocatalytic effect and good biocompatibility. In the present study, the effect of different chemical oxidation’s methods of multi-walled carbon nanotubes (MWCNTs) on the electrochemical behavior of modified graphite electrodes ...
متن کاملPreparation of supported gold nanoparticles by a modified incipient wetness impregnation method.
In this work, we show that if the mere procedure of impregnation of oxide supports with chloroauric acid, which is well-known to lead to large gold particles, is followed by a step of washing with ammonia, small gold particles (3-4 nm) can be obtained after a treatment of calcination at 300 degrees C on any type of oxide supports (alumina, titania, silica). Moreover, gold leaching is very limit...
