Three iso-specific organometallic catalysts for ethylene and propylene copolymerization with varying r1r2 parameters, i.e., the products of ethylene and propylene reactivity ratios, were utilized to synthesize equal-molecular-weight propylene-based elastomers (PBEs) of alternating, random, and blocky backbone sequences.
Xylanases catalyze the random hydrolysis of xylan backbone from plant biomass and thus, they have application in the production of biofuels, Kraft pulps biobleaching and feed industry.
The lower critical solution temperature (LCST) of brush copolymers in solution was adjusted as 35, 37 and 38 °C through random, gradient and block backbone structure respectively.
Except for random coil sections, all backbone dihedral angles resided in the well-defined, acceptable regions of the Ramachandran plot.
And then the nucleus gradually grew up and became increasing TiO2 nanorods along the backbones of the TiO2 tubes, along with a small quantity of free-grown rods random adhered to the backbones of the tubes.
In essence, we developed a novel method to increase recombinant protein production based on the random mutagenesis of vector backbones (epMEGAWHOP).
Varied grafting densities of the brushes were obtained through adjusting backbone structure as random, gradient and block respectively.
Three iso-specific organometallic catalysts for ethylene and propylene copolymerization with varying products of ethylene and propylene reactivity ratios were utilized to synthesize equal-molecular-weight propylene-based elastomers (PBEs) of alternating (aPBE), random (rPBE), and blocky (bPBE) backbone sequences.
Heat-induced fragmentation of RNA introduces mostly random breaks into the phosphodiester backbone.
With a given Rd.HMM most of the sequences emitted by the HMMER emit-module gave energy scores as poor as random sequences, when forced back into the original 3D backbone with ROSETTA design (not shown).
These ligands have the following properties: chitosan is a linear polysaccharide with a backbone characterized by a random distribution of β- 1-4 -linked d-glucosamine and N-acetyl-d-glucosamine units.
