Scanning electron microscopy (SEM) showed that the diameters of the obtained composite fibers were about 30–200 nm at different Fc concentrations. Thermogravimetric analysis (TGA) results confirmed the presence of ferrocene within the

• PVP nanofibers. X-ray diffraction (XRD) results showed that the crystalline structure of Fc in the fibers was amorphous after the electrospinning process. A biological evaluation of the antimicrobial activity of Fc/PVP nanofibers was carried out by using Gram-negative Escherichia coli (E. coli) as

Nanofibrous polymer materials produced by electrospinning have gained immense research interest because of their unique properties, such as high surface-area-to-volume and aspect ratios [3], and

The methodology is the following: (i) VA-CNTs are grown on a quartz substrate by catalytic pyrolysis, (ii) the film is immersed in an aniline/HCl solution (0 °C, 12 h), (iii) polymerization on the CNTs surfaces.

• ]. Cellulose fibers used for papermaking are hygroscopic in nature [9][10] and this property was used to our advantage when developing the antimicrobial paper. The adsorbed moisture can be utilized for the production of hydroxyl radicals (·OH) and/or hydrogen peroxide (H2O2) through photocatalysis. Both ·OH

• . As a result, the ZnO nanoparticles that are used for nucleating the nanorods get attached to the surface without the need for any further surface treatments, such as, for example, the surface treatment of polyethylene fibers with dodecane thiol for attachment of ZnO seed nanoparticles prior to

Since microcrystals usually only provide the structures of the basic aggregation units, different arrangements of these units into the protofilaments and then fibers may be probed in computer simulations. However, when no initial 3-D structural data is available, the

Due to the hybrid nature of 1', two opposing intermolecular interactions could dominate the self-assembly process, namely H-bonding and π–π stacking. Thus, a solvent-guided strategy was employed in order to gain control over the self-assembly process
