Sentence examples for framework positions from inspiring English sources
The active centers where selective oxidations with H2O2 proceed are identified in isolated TiIV substituting SiIV in framework positions: these react with H2O2 and form titanium peroxocompounds.
ZrSBA-15 support with Si/Zr = 20 containing majority of Zr in framework positions is synthesized by direct addition of Zr to the synthetic mixture.
Niobium species in the extra framework positions of MCM-41 catalysts are not active in the dibutyl sulphide oxidation with H2O2 unless they are leached to the solution.
We describe here their affinity maturation by error-prone PCR and ribosome display yielding clones with zero to seven (average 2.5) amino acid substitutions in framework positions.
When Ti ions are introduced in framework positions, reactive metal-oxo species are formed on contact with H2O2 or O2, which influence the mode of OO cleavage (heterolytic/homolytic) and product selectivity.
The DARPin with highest affinity (90 pM) carried four mutations at framework positions, leading to a 3000-fold affincreasecomparedompared to the consensus framework variant, mainly coming from a 500-fold increase of the on-rate.
A two-step post-synthesis method is used to prepare the V SiBEA reference system, with vanadium in framework position.
The charge transfer transition bands appear at 250 and 340 nm are attributed to the [VVO]3+ species in the tetrahedral framework position and in the surface wall, respectively.
UV vis results revealed that most of the Fe atoms in FeKIT-5 are in tetrahedral coordination and occupy framework position.
We observed an unexpected effect of a conserved mouse human framework position (L37) that hinders the binding of the humanized scFv to antigen.
We have determined the crystal structure of this DARPin at 1.7 Å, and found that a His to Tyr mutation at the framework position 52 alters the inter-repeat H-bonding pattern and causes a significant conformational change in the relative disposition of the repeat subdomains.
