In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 17057-04-4, name is 4-(2,5-Dioxo-2,5-dihydro-pyrrol-1-yl)-benzoicacid, introducing its new discovery. Computed Properties of C11H7NO4
Polybenzimidazole (PBI)-functionalized silica nanoparticles modified PBI nanocomposite membranes for proton exchange membranes fuel cells
Polybenzimidazole (PBI) has been chemically bonded to silica nanoparticles (SNPs) through an ozone-mediated process using N-(p-carboxyphenyl)maleimide (pCPM) functionalized SNPs (SNP-pCPM) as precursors, to enhance the interfacial compatibility between SNPs and PBI in PBI/SNP nanocomposites. The PBI-functionalized SNPs (SNP-PBI) have been well characterized and used as inorganic nanofillers for preparation of PBI/SNP-PBI membranes for fuel cells. Addition of PBI-SNP to PBI membranes enhances their thermal and mechanical properties as well as decreases their phosphoric acid uptakes. For the PBI/SNP-PBI membrane with 10wt% of SNP-PBI, it shows a proton conductivity of about 50mScm-1 at 160C, which is 25% higher compared to the pristine PBI membrane. Consequently, the PBI/SNP-PBI membrane demonstrates a maximum power density of 650mWcm-2 in a single cell test, compared to the value of 530mWcm-2 read from the test for pristine PBI membrane.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 17057-04-4, and how the biochemistry of the body works.Computed Properties of C11H7NO4
