The lack of an artificial system that mimics elemental sulfur (S8) oxidation by microorganisms inhibits a deep mechanistic understanding the cycle in biosphere and metabolism sulfur-oxidising microorganisms. In this article, we present biphasic biochemical under ambient conditions using liquid|liquid (L|L) electrochemical cell gold nanoparticles (AuNPs) as interfacial catalyst. interface betwee...

Two topologically different metallamacrocycles--S8 symmetric octanuclear gallium(III) metalladiazamacrocycle and pseudo-D4 symmetric octanuclear gallium(III) metalladiazamacrocycle--could be prepared using two similar heteroditopic bridging ligands having asymmetrical tridentate-bidentate binding residues.

The number of rich galaxy clusters per unit volume is a strong function of V, the cosmological density parameter, and s8, the linear extrapolation to z 5 0 of the density contrast in 8 h Mpc spheres. The Canadian Network for Observational Cosmology (CNOC) cluster redshift survey provides a sample of clusters, the average mass profiles of which are accurately known, which enables a secure associ...

The highly conserved nature of rRNA sequences throughout evolution allows these molecules to be used to build philogenic trees of different species. It is unknown whether the stability of specific interactions and structural features of rRNA reflects an optimal adaptation to a functional task or an evolutionary trap. In the work reported here, we have applied an in vivo selection strategy to de...

E. coli ribosomal proteins are retained by nitrocellulose filters. In contrast, 16S RNA passes through nitrocellulose filters. We have found that specific protein-RNA complexes involving single proteins also pass through nitrocellulose filters. Thus, by utilizing radioactively labeled r-proteins, nitrocellulose filtration can be used to study directly and sensitively the stoichiometry of r-prot...

The Evolved Packet Core (EPC), IP based, as defined by 3GPP, is the core network for the 4th generation networks. Within the EPC there are two mobility protocols defined to use on the S5/S8 interface between the Serving Gateway (SGW) and the Packet Data Network Gateway (PGW). The architecture and functionalities of the two involved gateways are different either of GPRS Tunnelling Protocol (GTP)...
