The aggregation and/or adhesion of bacterial cells is a serious disadvantage electrophoretic separations. In this study, physicochemical surface characteristics bacteria were measured to establish their role in and on the basis behavior different clinical strains Gram-positive Staphylococcus aureus Gram-negative Escherichia coli bacteria. number shape peaks obtained electropherograms connected with zeta potential measurements in-line microscope observation using specially designed CE...
The specific adsorption of citric acid ions at hydroxyapatite interface was investigated by the means radioisotope method (14C) as a function concentration, NaCl concentration and pH. Application has become wide in biomaterial field Ca10(OH)2(PO4)6 possess biocompatibility with human hard tissue. Hydroxyapatite synthesized using three different methods. physical properties resulting powder were characterized DTA/TG, XRD, AFM SEM microscopy. Physicochemical qualities characterizing electrical...
A series of composites based on nanohydroxyapatite (nHAp) and natural polysaccharides (PS) (nHAp/agar, nHAp/chitosan, nHAp/pectin FB300, APA103, nHAp/sodium alginate) was synthesized by liquid-phase two-step method characterized using nitrogen adsorption-desorption, DSC, TG, FTIR spectroscopy, SEM. The analysis adsorption-desorption data shows that with a nHAp: PS ratio 4:1 exhibit sufficiently high specific surface area from 49 to 82 m2/g. incremental pore size distributions indicate mainly...
Adsorption of 90Sr on hydroxyapatite is important in many fields life. The aim the paper was to discuss changes double electrical layer at hydroxyapatite/electrolyte solution interface during Sr ions adsorption and establish relations between time this material. Hydroxyapatite prepared by wet method, characterized X-ray diffraction accelerated surface area porosimetry methods. Studies were carried out using isotopes ionic solutions containing ion depending concentration pH solution....
Electrostatic stabilization is reduced in its efficiency an electrolyte-containing environment. The effect of electrolyte concentration mostly described as negative factor for dispersion stabilization. Usually, zeta potential and physical stability decrease at increasing concentration. purpose the present study was to measure surface properties nanotubes aqueous solution monovalent electrolytes different Characteristics such size distribution, chemistry, charge, dispersability phase have...
The study of the Cd(II) ions adsorption at hydroxyapatite/electrolyte solution interface and changes electrical double layer (EDL) structure in this system are presented. was calculated from loss their concentration using radioisotope method. studied range initial 0.000001 to 0.001mol/dm3 as function pH. results measurements kinetics on hydroxyapatite were fitted pseudo-first, pseudo-second, multiexponential modes check which model describes process best way. In addition, main properties...
Hydroxyapatite is a compound that belongs to the group of apatite minerals. It very interesting adsorbent and main inorganic component bones teeth. was obtained using three different methods. The samples were designated as HAP1, HAP2 HAP3. synthesized adsorbents characterized by following methods: thermal analysis, EDAX, XRD, FTIR, adsorption desorption nitrogen. electrochemical properties studied titration zeta potential. protein used bovine serum albumin; its concentration 5 mg/ml....
A series of TiO2–ZrO2/SiO2 nanocomposites were synthesized using a liquid-phase method and characterized by various techniques, namely, nitrogen adsorption–desorption, X-ray diffraction (XRD), photoelectron spectroscopy (XPS), Raman spectroscopy, high-resolution transmission electron microscopy, photon correlation (PCS). It was revealed that the component ratio calcination temperature affect phase composition nanocomposites. Composites TiZrSi1 (TiO2:ZrO2:SiO2 = 3:10:87) TiZrSi2 (10:10:80)...
Pristine fumed silica and powders with dried residuals of centrifuged aqueous suspensions silica, silica/PVP, or silica/protein were studied using nitrogen adsorption IR spectroscopy methods. The added polymers, surfactant, ethanol investigated by means photon correlation spectroscopy, 1H NMR, impact polymers on the suspension powder characteristics depends mechanism conformation polymer molecules (globular unfolded) due to strong weak intramolecular interactions. Globular proteins...
Although silica is one of the most common adsorbents, position its isoelectric point (IEP) on pH scale remains an open question. Different values from 1 to 4 have been published, and there even a controversy about very existence IEP. The discrepancies in literature are at least partially due application different instruments. zetameters produce zeta potentials acidic range
