Yellow-colored methylnitrocatechols (MNC) contribute to the total organic aerosol mass and significantly alter absorption properties of atmosphere. To date, their formation mechanisms are still not understood. In this work, intriguing role HNO2 (catalytic oxidative) in dark transformation 3-methylcatechol (3MC) under atmospherically relevant aqueous-phase conditions is emphasized. Three possible pathways 3-methyl-5-nitrocatechol 3-methyl-4-nitrocatechol formation, markedly dependent on...
At present, there are still numerous unresolved questions concerning the mechanisms of light-absorbing organic aerosol (brown carbon, BrC) formation in atmosphere. Moreover, is growing evidence that chemical processes atmospheric aqueous phase can be important. In this work, we investigate aqueous-phase BrC from 3-methylcatechol (3MC) under simulated sunlight conditions. The influence different HNO2/NO2− concentrations on kinetics 3MC degradation and was investigated. Under illumination,...
The development of sensitive, selective, and reliable glucose biosensors remains a persistent challenge in clinical diagnostics. In this study, we exploited the advantageous (electro)catalytic properties bismuth ruthenate (Bi2Ru2O7) pyrochlore clusters, known for their high surface activity metallic-like conductivity, favorable physicochemical multi-walled carbon nanotubes (MWCNTs) by combining them with oxidase (GOD) sensitive selective disposable biosensor. integration Bi2Ru2O7 enabled an...
Abstract. There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures coefficient at 532 1064 nm. Here we describe its design, calibration mode operation evaluate applicability, limits uncertainties. The nm channel was calibrated ∼ 1 µmol mol−1 NO2, whereas using measured size distribution spectra nigrosin particles Mie calculation. Since...
The characterization of organic matter (OM) and trace elements (TEs) was conducted in bulk precipitation samples collected an urban area Croatia (Zagreb center), from January 2009 to October 2011 (N = 31). Characterization OM performed by measurement dissolved (DOC) particulate forms carbon (POC), as well surface-active substances, copper complexing capacity reduced sulfur species which were determined electrochemically. Concentrations TEs (Al, Fe, Zn, Cr, Ba, Mn, Cu, Sr, Ti, Pb, V, Ni, Rb,...
The persistent nature of the SARS-CoV-2 virus, characterized by its large-scale periodical recurrence and high infectivity, has imposed an increasing demand for rapid frequent tests. This paper presents a simple, disposable, sensitive, selective label-free sensor impedimetric detection virus Spike S1 protein. We modified screen-printed carbon electrode with gelatin as biocompatible support to deposit protein A layer, acting structure-directing agent subsequent site-induced binding...
The ultimate goal in the understanding of complex chemical processes is a complete description underlying reaction mechanism. In present study and for this purpose, novel experimental platform introduced that builds upon electrochemistry capable generating reactive intermediate species at electrode surface. atmospherically relevant nitration catechols taken as case example. First, we confirm recently proposed mechanism, advancing atmospheric brown carbon formation dark. We are able to...
New particle formation (NPF) is considered a major source of aerosol particles and cloud condensation nuclei (CCN); however, our understanding NPF the subsequent growth mechanisms in coastal areas remains limited. This study provides evidence frequent events followed by middle Adriatic Sea during summer months at station Rogoznica Croatia. To knowledge, this first to report such region. Our research aims improve investigating through detailed physicochemical characterization event...
(Jacq.) Swartz is a perennial herbaceous climbing plant with tendrils and tuberous roots belonging to the Cucurbitaceae family. Its fruits ("chayote"), stems, roots, leaves are edible commonly ingested by humans. It has shown medicinal properties attributed its bioactive compounds (vitamins, phenolic acids, flavonoids, carotenoids, triterpenoids, polyphenolic compounds, phytosterols, cucurbitacins), which together have been associated control prevention of chronic infectious diseases,...

Quantifying the anthropogenic metals concentrations in black crust (BCs) developing on surface of historic buildings, gives a general overview environmental pollution.In this study, trace elements were determined by ICP-MS samples BCs from monuments two urban cities: Zagreb (Croatia) and Jajce (B&H).Higher concentration sample than those Zagreb, can be associated to age monument different pollution sources.
