The acid-base properties of two bifunctional 3-hydroxy-4-pyridinone ligands and their chelating capacity towards Zn2+, an essential bio-metal cation, were investigated in NaCl aqueous solutions by potentiometric, UV-Vis spectrophotometric, 1H NMR spectroscopic titrations, carried out at 0.15 ≤ I/mol -1 1.00 288.15 T/K 310.15. A study I = mol L-1 T 298.15 K was also performed for other three Zn2+/Lz- systems, with belonging to the same family compounds. processing experimental data allowed...
In this study, hydrogels were produced using a Schiff base reaction between two hyaluronic acid derivatives: one containing aldehyde groups (HA-Ald) and the other holding diethylenetriamine with terminal amino (HA-DETA). The DETA portion promotes in situ growth, complexation, stabilization of silver nanoparticles (AgNPs), eliminating need for external reducing agents. HA-DETA HA-Ald leads to formation imine bonds, which results dynamically pH-responsive cross-linking. While capping ability...
In this paper, new information on physical and chemical properties of the widely used nanostructured Halloysite mineral are reported. Given that has a tubular structure formed by variable number wrapped layers containing Si–OH Al–OH groups, their proton binding affinity was measured at different ionic strengths media means potentiometric measurements in heterogeneous phase. One protonation constant for groups two were determined. The values increase with increasing strength all media. This...
Halloysite nanotubes were functionalized with bis-vinyl imidazolium salts and PdNPs to obtain an efficient catalyst for fine chemical synthesis.
Abstract Water is essential for humans, animals, and plants; pollutants, usually derived from anthropogenic activities, can have a serious effect on its quality. Heavy metals are significant pollutants often highly toxic to living organisms, even at very low concentrations. Among the numerous removal techniques proposed, adsorption onto suitable adsorbent materials considered be one of most promising. The objective current study was determine effectiveness halloysite nanotubes (HNT)...
Abstract In the growing Industry 4.0 market, there is strong need to implement automatic inspection methods support manufacturing processes. Tool wear in turning one of biggest concerns that most expert operators are able indirectly infer through analysis removed chips. Automatising this operation would enable developing more efficient cutting processes turns easier process planning management toward Zero Defect Manufacturing paradigm. This paper presents a deep learning approach, based on...
Mineral extraction from seawater brines has emerged as a viable solution to reduce Europe's reliance on imported Critical Raw Materials (CRM). However, the economic viability of this approach hinges local demand for sodium chloride, primary product such processes. This study investigates potential residual brines, commonly known "bitterns," generated during solar sea-salt in traditional saltworks, an alternative source minerals. The Mediterranean region, encompassing South-European,...
A kinetic and thermodynamic study on the sorption ability of calcium alginate gel beads towards Pd(II) ion was made in aqueous solution at different pH chloride concentrations. The experimental conditions adopted experiments were established basis a speciation Pd2+-AA system which all side reactions, such as hydrolysis Pd(II), protonation interactions ligand metal with ions ionic medium taken into account. In range 2–5 concentration 0 ⩽ CCl-/mmol L−1 10 showed good confirmed by data...
Trace metal concentrations were measured in different tissues of Sabella spallanzanii, Styela plicata, and Mytilus galloprovincialis collected the Termini Imerese Harbor (Sicily, Italy) to evaluate potential use these species as bioindicators. Higher bioaccumulation factors (BAFs) calculated tube S. except for As, which had a higher BAF branchial crown same species. Regarding other analyzed, BAFs found digestive gland M. galloprovincialis. An exception was Pb, significantly more concentrated...
The acid-base properties of pectin and its ability to complex with copper(II) or cadmium(II) were quantitatively determined in order define the this natural polyelectrolyte sequester metal ions. Potentiometric measurements carried out at different ionic strengths (0.1 - 0.7 mol L-1, Na+ medium) allowed us together dependence protonation constants on strength calculate constant infinite dilution. formation species between was investigated potentiometrically (using H+, Cu2+ Cd2+ Ion Selective...
Complex shaped stainless steel tubes are often required for special purpose biomedical equipment. Nevertheless, traditional manufacturing technologies, such as extrusion, lack the ability to compete in a market of customized complex components because associated expenses towards tooling and extrusion presses. To rapid manufacture few with low cost high precision, new Extrusion based Additive Manufacturing (EAM) process, is proposed this paper, an example, short 316L sectioned were prepared...
