• high efficacy in the treatment of cognitive/memory disorder [32]: nootropic, neurotrophic, neuroprotective and anti-inflammatory effects, a high affinity for copper(II) ions, and a protective ability against metal-induced cell toxicity have been observed [33][34][35][36]. Hence, the role of Semax in

• particles prepared by addition of copper(II) ions exhibit for this ratio a pronounced two-dimensional and disk-like morphology with a diameter of a single silica fiber of about 30 nm (Figure 7). Usage of calcium(II) ions alters the morphology to spherical structures (Figure 8). Calcination of the metal

• sorption measurements. The overall morphology is more or less preserved for the immobilization of these modified aggregates on the carbon fiber surface. Addition of copper(II) ions leads to two-dimensional, fan like structures located on the fiber surface, whereas calcium(II) ions redirect the morphology

• towards a pronounced three-dimensional structure (Figure 9). The diameter of the composite fiber reaches 12 µm in the case of copper(II) ions and up to 100 µm for the incorporation of calcium(II) ions accompanied with a less smooth coating. Thus metal ions can be incorporated in the silica shell

• molecular structure of the surfaces. It was demonstrated that the introduction of short hydrophobic (methyl) groups improves the kinetic characteristics of the samples during the sorption of copper(II) ions and promotes fixation of aminopropyl groups on the surface of silica microspheres. The introduction

• curves for the samples fit the pseudo-second-order model (Figure 4). The fastest is the reaction on amino/methyl bifunctional samples, where the equilibrium is reached within 30 min. Thus, based on the kinetic curves, specific times for the adsorption of copper(II) ions were chosen for each sample. The

• because this species is highly unstable. With a predicted reduction potential between −1.98 and −1.10 V versus NHE [46] CO2−• is very likely to reduce adjacent copper(II) ions by decaying to more CO2. This must yield copper(I) ions. The reduction step required for the formation of metallic copper then
