Miniaturization of polymeric robots leads to difficulties in actuation inside viscous media due the increased surface drag on diminutive robot bodies. Herein, agile underwater swimming microrobots is presented with investigation correlation between magnetic propulsion and robot. The swim pivoting tumbling motions during rotation by in-plane two permanent magnets underneath plane, which results ...

Main agent orange-red coloured pigment of henna is a molecule called Lawson which is responsible for anti-microbial, anti-tumor, anti-inflammatory and analgesic activity. Chitosan is a biopolymer with high strength, biocom-patibility and biodegradability, non-toxicity and antimicrobial properties. Electrospinning is a method of producing su-bmicron polymeric fibers with high porosity and high s...

Functionalized polymeric microspheres based on a modifed polyether ether keetone (PEEK-WC) using immersion precipitation techniques were successfully prepared by doping initial polymeric solutions with DEHPA. The viscosity of the doping solution was measured for determining the optimal value for obtaining reproducible capsules. The modifed microspheres were characterize...

Flexible thermoresponsive polymeric microjets are formed by the self-folding of polymeric layers containing a thin Pt film used as catalyst for self-propulsion in solutions containing hydrogen peroxide. The flexible microjets can reversibly fold and unfold in an accurate manner by applying changes in temperature to the solution in which they are immersed. This effect allows microjets to rapidly...

Run-and-tumble motility is widely used by swimming microorganisms including numerous prokaryotic and eukaryotic organisms. Here, we experimentally investigate the run-and-tumble dynamics of the bacterium E. coli in polymeric solutions. We find that even small amounts of polymer in solution can drastically change E. coli dynamics: cells tumble less and their velocity increases, leading to an enh...

In this paper we follow the lines of recent works to investigate systems of two coupled real scalar fields defined by potentials that describe periodic interactions between the scalar fields. We work with polymeric chains containing periodic interactions between the coupled fields, and we investigate the topological sectors to obtain explicit soliton solutions and their corresponding energy. In...
