Industrial spray coating processes are known to produce excellent coatings on large surfaces and thus often used for in-line production. However, they could be one of the most critical sources worker exposure ultrafine particles (UFPs). A monitoring campaign at Witek s.r.l. (Florence, Italy) was deployed characterize release TiO2 NPs doped with nitrogen (TiO2-N) Ag capped hydroxyethyl cellulose (AgHEC) during automatic industrial spray-coating polymethyl methacrylate (PMMA) polyester....
Room temperature phosphorescence is usually a prerogative of metal complexes. Molecules with hexakis(phenylthio)benzene core constitute rare example all-organic chromophores induced by environmental rigidification. Here we report covalent encapsulation functionalized persulfurated benzene into silica nanoparticles as method rigidification for induction phosphorescence. The developed display bright at ambient temperatures and possess high colloidal stability in water. permits incorporation...
Several parameters have a critical importance for the stabilization of either polyproline I (PPI) or II (PPII) helices in hydrophobic environment. Among them, it was found out that concentration is crucial as polyprolines at 3 mM stably fold PPII helices, are organized aggregates stable even after several days and detectable by dynamic light scattering analysis. In more diluted same molecules PPI no found. contrast, introduction (4S,5R)-4-carboxy-5-methyloxazolidin-2-one (l-Oxd) moiety...
The structure–properties relationship in a series of carbonyl rhenium(I) complexes based on substituted terpyridine ligands general formula [Re(κxN-Rtpy)(CO)yL]n+ is explored by both experimental and theoretical methods. In these compounds, the adopt bidentate (κ2N) terdentate (κ3N) coordination modes associated with three or two carbonyls, respectively. Conversion from κ2N to κ3N mode leads large changes absorption spectra oxidation potentials due destabilization HOMO level each complex....
An automatic lab-scaled spray-coating machine was used to deposit Ag nanoparticles (AgNPs) on textile create antibacterial fabric. The spray process monitored for the dual purpose of (1) optimizing by maximizing silver deposition and minimizing fluid waste, thereby reducing suspension consumption (2) assessing AgNPs release. Monitoring measurements were carried out at two locations: inside outside chamber (far field). We calculated efficiency (E), finding it be enhanced increasing pressure...
Stepwise self-assembly processes using new lanthanide metalloligands (Ln–MLs) and silver salts have been successfully applied to isolate 4f–4d heterometallic coordination networks of four different structural types. In particular, the tetrakis–chelate complexes NEt4[Ln(L1)4] [HL1 = 1,3-bis(4′-cyanophenyl)-1,3-propanedione; Ln Eu (1a), La (1b), Nd (1c), Tb (1d)] NEt4[Ln(L2)4] (HL2 1,3-bis(4′-pyridyl)-1,3-propanedione; (1e), (1f)] synthesized, characterized, reacted with salts. The use allowed...
Spray coatings' emissions impact to the environmental and occupational exposure were studied in a pilot-plant. Concentrations measured inside spray chamber at work room Near-Field (NF) Far-Field (FF) mass flows analyzed using mechanistic model. The coating was performed ventilated by spraying titanium dioxide doped with nitrogen (TiO
In this paper, we demonstrate the realization process of a pragmatic approach on developing template for capturing field monitoring data in nanomanufacturing processes. The serves fundamental principles which make scientifically Findable, Accessible, Interoperable and Reusable (FAIR principles), as well encouraging individuals to reuse it. our case, shepherds’ (the guider data) creation workflow consists following steps: (1) Identify relevant stakeholders, (2) Distribute questionnaires...
Cyclopeptides (CPs) have been recognized as excellent templates for the rational design of biologically active compounds. However, in absence constraining elements, even small cyclotetrapeptides (CTPs) and cyclopentapeptides (CPPs) may show conformational heterogeneity, with occurrence mixtures cis/trans ‐peptide bonds. In this paper, we discuss synthesis CTP CPP model compounds containing 5‐aminomethyloxazolidine‐2,4‐dione (Amo)‐dipeptide scaffolds, which combine a β/α‐hybrid dipeptide...
Antibiotic resistance is emerging as a growing worldwide problem and finding solutions to this issue becoming new challenge for scientists. As the development of drugs slowed down, advances in nanotechnology offer great opportunities, with possibility designing systems carrying, delivery administration already use. Engineered combinations synthetic, broad-spectrum antibiotic ofloxacin, rarely studied field, different types silver, mesoporous silica-based Pluronic/silica-based nanoparticles...
Metal nanoparticles are reported to be toxic due the generation of free radicals at their surface. Relatively inert thiol-capped gold (AuNPs) have been induce radical formation in presence hydroperoxides, which would conflict with potential use as scaffolds for design novel nano-antioxidants. With aim clarifying this aspect, we investigated pro-oxidant activity dodecanethiol-capped AuNPs (∼5 nm diameter), prepared through Brust-Schiffrin synthesis, by oxygen-uptake kinetic studies. The was...
The use of colloid supported lipid bilayers (CSLBs) for assembling colloidal structures has been recent interest. Here, we multi-component bilayer membranes formed around anisotropic colloids and show that the curvature anisotropy drives a sorting lipids in membrane along colloids. We then exploit this curvature-sensitive to create "shape-anisotropic patchy colloids" - specifically, with six rods sticking out central cubic core, "hexapods", purpose demonstrate patches self-assemble at tip...
Background: Photocatalytic air purifiers based on nano-titanium dioxide (TiO 2) visible light activation provide an efficient solution for removing and degrading contaminants in air. The potential detachment of TiO 2 particles from the purifier to indoor could cause a safety concern. A release was measured one commercially available photocatalytic "Gearbox Wivactive" ensure successful implementation purifying technology. Methods: In this study, studied under laboratory-simulated conditions...
Abstract Some hybrid foldamers of various length, all containing the (4 R ,5 S )‐4‐carboxy‐5‐methyloxazolidin‐2‐one ( d ‐Oxd) moiety alternating with an l ‐amino acid ‐Val, ‐Lys, or ‐Ala), were prepared in order to study their preferred conformations and evaluate biological activity. Surprisingly, only longer oligomers ‐Ala fold into well‐established helices, whereas other give partially unfolded turn structures. Nevertheless, they show good biocompatibility, no detrimental effects up 64 μ m...
