The phenomenon of solid dissolution into a solution constitutes fundamental aspect in both natural and industrial contexts. Nevertheless, its intricate nature at the microscale poses significant challenge for precise quantitative characterization foundational level. In this work, influence across three specific cleavage planes, namely (100), (111), (110) on kinetics fluorite aqueous environments was examined from experimental theoretical standpoints. For very first time, surface potential...
Plastic contamination has become one of the most pressing environmental issues due to rapidly increasing production disposable plastic products, their fragmentation into smaller pieces, and long persistence in environment, which affects all living organisms, including plants. In this study, Allium cepa roots were exposed 0.01, 0.1, 1 g L−1 commercial polystyrene (PS-MPs) polymethyl methacrylate microparticles (PMMA-MPs) for 72 h. Dynamic light scattering (DLS) analyses showed high stability...
Calcite is the most stable polymorph of calcium carbonate (CaCO3) under ambient conditions and ubiquitous in natural systems. It plays a major role controlling pH environmental settings. Electrostatic phenomena at calcite–water interface surface reactivity calcite general have important implications. They may strongly impact nutrient contaminant mobility soils other subsurface environments, they control oil recovery from limestone reservoirs, safety nuclear waste disposal sites. Besides...
BPA is a plasticizer for the production of polycarbonate plastics and epoxy resins widely used in household goods, including food packaging. Free known to migrate from packaging food, its uptake has been associated with adverse health effect, particularly disruption endocrine activity. The presence migration plastic consumer products are subject strict regulation EU. aim this study analyse different items sold on Croatian market. To simulate real life exposure, we treated samples simulant....
We studied the charging of inert surfaces (polytetrafluoroethylene, i.e., PTFE; graphite; graphene; and hydrophobic silica) using classical colloid chemistry approaches. Potentiometric titrations showed that these acquired less charge from proton-related reactions than oxide minerals. The data batch-type for PTFE powder did not show an effect ionic strength, which was also in contrast with results colloids. In agreement colloids, electrokinetic typical salt level dependence. some cases,...
The adsorption of cetyltrimethylammonium bromide (CTA+Br-) on sapphire-c surfaces was studied at pH 10 below the surfactants' critical micelle concentration. evolution interfacial potentials as a function CTAB concentration characterized by surface and zeta potential measurements complemented molecular dynamic (MD) simulations well second-harmonic (SHG) vibrational sum-frequency generation (SFG) spectroscopy. changes in suggest that negative charge due to deprotonated aluminols groups is...
In this study, the surface properties of Ti/TiO2 substrate before and after adsorption polyelectrolytes were investigated. As model polyelectrolytes, strongly charged polycation poly(diallyldimethylammonium) (PDADMA) polyanion poly(4-styrenesulfonate) (PSS) used. Initially, bare titanium was characterized by means ellipsometry, atomic force microscopy (AFM), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) measurements inner potential using crystal electrode (CrE). It...
Environmental contextSolubility and dissolution rates of mineral surfaces depend on both the surface properties composition aqueous solution. We investigated link between interfacial reactions a fluorite crystal. The study provides detailed microscopic picture phenomena at surface, results have wider application to general processes taking place in environment. AbstractDissolutions (111) crystallographic plane (CaF2) colloidal particles were studied as function pH. process was examined by...
Organic matter (OM) interactions with minerals are essential in OM preservation against decomposition the environment. Here, by combining potentiometric and electrophoretic measurements, we probed mode of coordination role pH-dependent electrostatic between organic acids an iron oxide surface. Specifically, show that malonate ions adsorbed to a hematite surface wide pH window 3 8.7 (point zero charge). The varied this range depended on acid acidity constants. In acidic environment, potential...
In this study, the surface properties and corrosion behavior of a titanium sample modified with an electrochemically formed oxide layer (Ti|TiO 2 ) Ti|TiO coated poly( N -ethyl-4-vinylpyridinium) cations (PE4VP) were studied.
The Data in Brief contains data on the electrokinetic mobility of PTFE and silica particles aqueous suspensions as a function pH temperature. Furthermore, concomitant conductivities values are reported both for systems absence presence temperature compatible with associated research paper "The influence charging Polytetrafluoroethylene surfaces electrolyte solutions" (Barisic et al.). trend can be inferred from this kinds particles. evolution measured valuable input future models that...
Abstract Adsorption of polyions, strongly charged poly(N-ethyl-4-vinylpyridinium) cation (P4VP) weakly poly(allylammonium) (PAH) and poly(acrylate) anion (PAA) on TiO 2 surface was investigated. The selected polyions have different functional groups degree polyion ionization, which affects the interactions with surface. effect adsorption inner potential electrokinetic were measured analyzed. by means single crystal (SCr) electrodes two orientation (001) (100). titania particles obtained from...
