In the processes of protein synthesis and folding, newly synthesized polypeptides are tightly connected to the macromolecules, such as ribosomes, lipid bilayers, or cotranslationally folded domains in multidomain proteins, representing a hallmark of de novo protein folding environments in vivo. Such linkage effects on the aggregation of endogenous polypeptides have been largely neglected, altho...

Recent developments in water-soluble hydrophobically associating polymers are examined with particular emphasis on their use for oilfield applications. These polymers have potential for use in EOR, acidizing, drilling fluids, completion fluids and profile modification. They have also been reported to selectively reduce water permeability in sandstones, and have been used as drag-reducing agents...

This paper describes the effects of graft architecture of poly(N-isopropylacrylamide) (PIPAAm) brush surfaces on thermoresponsive aqueous wettability changes and the temperature-dependent hydrophobic interaction of steroids in silica capillaries (I.D.: 50 μm). PIPAAm brushes were grafted onto glass substrates by surface-initiated atom transfer radical polymerization (ATRP) that is one of the li...

This study examines the removal of p-CBA via application heterogeneous catalytic ozonation in presence 13 minerals. The solids were used as raw materials or after hydrophilic/hydrophobic modification. optimal minerals zeolite, calcite, dolomite, and thermally treated talc. kinetic showed that decomposition ozone followed a first-order model for all systems, whereas depended on applied. degradat...

Kinetic resolution of racemates with lipases is the preferred method for producing bioactive compounds. One strategy obtaining highly enantioselective that are stable in organic media often used these reactions to improve existing by protein engineering. In this work, we engineered lipase LipC12, which has good stability media, but only moderate enantioselectivity. Molecular docking LipC12 iden...

Abstract Hydrophobic metakaolin-based flat sheet membrane was developed via phase inversion and sintering technique modified through 1H,1H,2H,2H-perfluorooctyltriethoxysilane grafting agents. The prepared characterized by different techniques such as XRD, FTIR, SEM, contact angle, porosity, mechanical strength. Their results indicated that the wettability, structural, properties of confirm suit...

Commercial purity titanium (CP-Ti) and a Ti-6Al-4V alloy (Ti64) were processed by high-pressure torsion (HPT) for 10 20 turns. The HPT processing produced nanostructured microstructure significant strength enhancement in the CP-Ti Ti64 samples. After turns, samples of HPT-processed subjected to laser surface treatments an air atmosphere using different scanning speeds powers. roughness laser-mo...

Unspecific adhesion of bacteria is usually the first step in the formation of biofilms on abiotic surfaces, yet it is unclear up to now which forces are governing this process. Alongside long-ranged van der Waals and electrostatic forces, short-ranged hydrophobic interaction plays an important role. To characterize the forces involved during approach and retraction of an individual bacterium to...
