Bionic self-cleaning surfaces with well-ordered polymer nano-fibers are firstly fabricated by disturbing crystallization during one-step coating-curing process. Orderly thin (100 nm) and long (5-10 μm) polymer nano-fibers with a certain direction are fabricated by external macroscopic force (F blow) interference introduced by H2 gas flow, leading to superior superhydrophobicity with a water con...

A variety of nano-carriers, nano-particles, nano-fibers, nano-tubes etc. have displayed greater competence to mimic nanoscale environment for the enzyme as compared to microand macro-environments provided by traditional support carriers that have been commonly employed for enzyme immobilization. The porous structured beads (silica, alginate etc.), membranes and fibers (>100 μm) have some inhere...

The surface concentration of CBD-FITC conjugates, adsorbed on cellulose fibers, was determined by image analysis. The program consists of two scripts, the first dedicated to the elaboration of the calibration curve. The emission of fluorescent light, detected by image analysis, is correlated with the concentration of CBD solutions. This calibration is then used (second script) to determine the ...

Wood-derived cellulosic fibers prepared in different ways were successfully employed to absorb simulated crude oil, demonstrating their possible use as absorbents in the case of oil spills. When dry fibers were used, the highest sorption capacity (six parts of oil per unit mass of fiber) was shown by bleached softwood kraft fibers, compared to hardwood bleached kraft and softwood chemithermomec...

Many bacteria are harmless and even highly helpful but a lot of them can cause hundreds of illnesses [1]. Therefore, there exists a need to develop antibacterial supports which exhibit satisfactory antibacterial properties allowing the protection of the human body. Cellulose is one of the most abundant biopolymers in the nature. It is a renewable material which exhibited hygroscopicity, non-tox...

PLLA fibrous tissue scaffolds with controlled fiber nanoscale surface roughness are fabricated with a novel centrifugal jet spinning process. The centrifugal jet spinning technique is a highly efficient synthesis method for micron- to nano-sized fibers with a production rate up to 0.5 g min(-1). During the centrifugal jet spinning process, a polymer solution jet is stretched by the centrifugal ...

A novel route to fabricate nano-fiber anode material for solid oxide fuel cells (SOFCs) is presented. Firstly, uniform nano-fibers of 8 mol % Yttria Stabilized Zirconia (8YSZ) were formed in an electrospinning process; then, these electrospun fibers were calcined at temperatures up to 1300 °C; and finally the ceramic 8YSZ nano-fibers were coated with nickel in an electroless plating process. Th...
