Advances in the research of nanoparticles (NPs) with controlled charge and size are driven by their potential application development novel technologies innovative therapeutics. This work reports synthesis, characterization, comprehensive biological evaluation AgNPs functionalized N,N,N-trimethyl-(11-mercaptoundecyl) ammonium chloride (TMA) trisodium citrate (TSC). The prepared were well characterized terms morphological, spectroscopic functional properties activities. implementation several...
Designing supramolecular gelators with targeted properties is very difficult and mainly relies on structural modifications of known gelator molecules. However, often, even minor can result in the complete loss gelation capabilities. In present work, we have studied influence role silver nanoparticles (AgNPs) trisodium citrate (TSC) additives self-assembly process alanine derivative (C12Ala) intermolecular interactions resulting hydrogel systems enhanced stability sustainability. The effect...
A new type of silver nanoparticles (AgNPs) was prepared and comprehensively studied. Scanning electron microscopy (SEM) dynamic light scattering (DLS) analyses indicated that 24 nm AgNPs with narrow size distribution were obtained while Z-potential confirms their good stability. The composites the nontoxic-nature-inspired hydrogel formed upon cooling aqueous solution C12Ala. thermal gravimetric analysis (TGA) differential scanning calorimetry (DSC) do not show significant shifts in...
Surfactants with amino-acid heads (AASs), namely N-lauroyl-l-alanine (C12-ALA), N-lauroyl-l-leucine (C12-LEU), and N-lauroyl-l phenylalanine (C12-PHE) were mixed n-octanol (C8OH) thoroughly investigated via surface tension foamability experiments. Significant differences between the selected AAS observed. Moreover, results obtained under equilibrium dynamic conditions remarkably different in terms of activity. The measurements (equilibrium conditions) indicated that C12-ALA/C8OH mixture...
The adsorption characteristics of amino acid surfactants, synthesized as substances with different volumes and hydrophilic head properties, have been previously described experimentally, without robust theoretical explanation. A model enabling the characterization behavior physicochemical properties this type biodegradable based on molecular structure, would be beneficial for assessment their usefulness in colloids interface science comparison typical surface-active substances. In paper,...
Data in the literature on influence of water temperature terminal velocity a single rising bubble are highly contradictory. Different variations with reported even for potentially pure systems. This paper presents systematic study between 5 °C and 45 motion practically constant size (equivalent radius 0.74 ± 0.01 mm) clean n-pentanol solution different concentrations. The was measured by camera, an ultrasonic sensor reproduced numerical simulations. Results obtained image analysis (camera)...
Polymer stamping is a reliable and cost-effective method for producing charged patterned surfaces. However, charge stability limited, they discharge steadily while immersed in polar solvents. Here, we applied polyelectrolytes as the medium to increase this stability. Charged line patterns were fabricated by pressing polydimethylsiloxane (PDMS) stamp covered with polyethylenimine (PEI) solution against silicon, glass, or polystyrene. Then, substrate was of oppositely silver nanoparticles....
A significant interest in the versatile and controlled fabrication of surface coatings is present nowadays materials science. Here we a repeatable efficient method obtaining polystyrene (PS) layers based on use deposition nanoparticles (PS-NPs) strictly defined amount forming smooth (RMS below 1 nm) coating by melting them. Due to dependence between concentration applied thickness obtained homogeneous layer, it possible control PS straightforwardly. Moreover, this technique, initial solvent...
This work explores the behavior of chiral compound mixtures enriched in one enantiomers whilst a typical chromatography on achiral stationary phase is employed. The influence several factors, such as eluent composition, ratio to phase, and initial enatiomeric purity used distribution collected chromatographic fraction, was studied. obtained results indicate that phenomenon Self Disproportionation Enantiomer (SDE) occurred all cases, some fractions got higher optical purities than one. Thus,...
This study investigates the self-assembly of magnetic nanoparticles into a flat nanocomposite surface with concealed patterns. The application multilayer stamping medium and presence field gradient would enable attraction organization superparamagnetic iron oxide (SPIONs) onto predefined areas, corresponding to pre-fabricated layer. experimental approach involved preparing patterned surfaces by applying poly(ethyleneimine) (PEI) poly(styrene sulfonate) (PSS) as medium. SPIONs selectively...
