Bio-polymerization processes like transcription and translation are central to proper function of a cell. The speed at which the bio-polymer grows is affected both by the number of pauses of elongation machinery, as well the number of bio-polymers due to crowding effects. In order to quantify these effects in fast transcribing ribosome genes, we rigorously show that a classical traffic flow mod...

The influence of temperature on the resistance to rapid crack propagation a semi-crystalline bio-based polymer was studied. experimental results described in this study allow initiate first discussion role viscosity and its link with fracture behaviour heterogeneous microstructure such as semi-crysalline polymer. Dynamic tests pipes were carried out. It would appear that decrease approximately ...

Plasma-based approaches have gained considerable popularity for the creation of surfaces designed to be in contact with biological environments (‘bio-interfaces’). Many studies have been reported using various approaches and process gases. Initially a number of studies explored the potential of plasma-produced surfaces or coatings to control bio-interfacial interactions. More recently, the majo...

An important challenge for scientific research is the production of artificial systems able to mimic the recognition mechanisms occurring at the molecular level in living systems. A valid contribution in this direction resulted from the development of molecular imprinting. By means of this technology, selective molecular recognition sites are introduced in a polymer, thus conferring it bio-mime...

A novel actuating material, which is lightweight, soft, and capable of generating large flapping motion under electrical stimuli, is highly desirable to build energy-efficient and maneuverable bio-inspired underwater robots. Ionic polymer-metal composites are important category of electroactive polymers, since they can generate large bending motions under low actuation voltages. IPMCs are ideal...

A synthetic polymeric lens was designed and fabricated based on a bio-inspired, "Age=5" human eye lens design by utilizing a nanolayered polymer film-based technique. The internal refractive index distribution of an anterior and posterior GRIN lens were characterized and confirmed against design by µATR-FTIR. 3D surface topography of the fabricated aspheric anterior and posterior lenses was mea...

The use of cost effective solvents may be necessary to store wood pyrolysis bio-oil in order to stabilize and control its viscosity, but this part of the production system has not been explored. Conversely, any rise in viscosity during storage, that would occur without a solvent, will add variance to the production system and render it cost ineffective. The purpose of this study was to modify b...

We report a facile approach to the construction of patterns of biomolecules based on polymeric self-assembled monolayers (pSAMs) that possess dual functions: "bio-reactive (post-functionalizable)" and "bio-inert (anti-biofouling)" properties. To prepare pSAMs on Si/SiO2 wafers were synthesized new random copolymers by radical polymerization of poly(ethylene glycol) methyl ether methacrylate (PE...
