An ordered mesoporous carbon, CMK-3, was synthesized using a mesoporous siliceous material, SBA-15, as the template. CMK-3 was characterized and used for the adsorption of fullerenes C60 and C70. It was found that the adsorption capacity of CMK-3 is 4 times higher than that of activated carbon. The adsorption equilibrium isotherms of C60 and C70 on CMK-3 were studied for both single and binary ...

The removal of formaldehyde at low concentrations is important in indoor air pollution research. In this study, mesoporous carbon with a large specific surface area was used for the adsorption of low-concentration indoor formaldehyde. A mesoporous carbon material, CMK-3, was synthesized using the nano-replication method. SBA-15 was used as a mesoporous template. The surface of CMK-3 was activat...

Synthetic caspase inhibitors and particularly broad-spectrum caspase inhibitors can prevent cells from death or at least slow down cell death process and abrogate some apoptotic hallmarks [Kitanaka, C., Kuchino, Y., 1999. Caspase-independent programmed cell death with necrotic morphology. Cell Death and Differentiation 6, 508-515]. However, not all synthetic caspase inhibitors diminish cell dea...

The crystal structure of Staphylococcus aureus cytidine monophosphate kinase (CMK) in complex with cytidine 5'-monophosphate (CMP) has been determined at 2.3 angstroms resolution. The active site reveals novel features when compared with two orthologues of known structure. Compared with the Streptococcus pneumoniae CMK solution structure of the enzyme alone, S. aureus CMK adopts a more closed c...

Human neutrophils are a likely source of elastase in the pathogenesis of human pulmonary emphysema. A study was undertaken to determine whether emphysema, induced in hamsters by intratracheal treatment with human neutrophil elastase (HNE), could be ameliorated by intratracheal instillation of succinyl-alanyl-alanyl-prolyl-valine-chloromethyl ketone (CMK). One mg of CMK was given to hamsters 1 h...

To utilize the high specific capacity of SnO2 as an anode material in lithium-ion batteries, one has to overcome its poor cycling performance and rate capability, which result from large volume expansion (∼300%) of SnO2 during charging-discharging cycles. Hence, to accommodate the volume change during cycling, SnO2 nanoparticles of 6 nm diameter were synthesized specifically only on the outer s...

Ordered mesoporous carbons with various structures, designated as CMK-1~5, have been synthesized by carbonization of sucrose, furfuryl alcohol or other suitable carbon sources inside silica or aluminosilicate mesopores that are interconnected into three-dimensional networks such as in MCM-48 (cubic Ia3d), SBA-1 (cubic Pm3n) and SBA-15 (hexagonal p6mm). The mesoporous carbon molecular sieves, ob...

A gene encoding a polypeptide of 25 kDa is located immediately upstream of the gene for ribosomal protein S1, rpsA. In high gene copy number, this gene, mssA, was previously found to suppress defects in smbA, which is now known to be identical to pyrH, encoding UMP kinase. We show here that the 25-kDa polypeptide comprises CMP kinase and propose that the gene be designated cmk. In a strain dele...
