Homoleptic mono-, di-, and tetra-iron complexes featuring phosphido ligands: a synthetic, structural, and spectroscopic study
PublicationWe report the first series of homoleptic phosphido iron complexes synthesized by treating either the β-diketiminato complex [(Dippnacnac)FeCl2Li(dme)2] (Dippnacnac = HC[(CMe)N(C6H3-2,6-iPr2)]2) or [FeBr2(thf )2] with an excess of phosphides R2PLi (R = tBu, tBuPh, Cy, iPr). Reaction outcomes depend strongly on the bulkiness of the phosphido ligands. The use of tBu2PLi precursor led to an anionic diiron complex 1 encompassing a planar...

Application of deep eutectic solvents in analytical sample pretreatment (update 2017–2022). Part A: Liquid phase microextraction
PublicationSustainable development in all branches of human activity has become an unequivocal necessity in the last two decades, and green chemistry goes hand in hand with it. Various ways have been proposed in analytical chemistry to meet the current requirements of green chemistry. One such approach is the research of new reagents and solvents for analytical purposes. Deep eutectic solvents (DESs) began being investigated and used in analytical...

Synthetic, Structural, and Spectroscopic Characterization of a Novel Family of High-Spin Iron(II) [(β-Diketiminate)(phosphanylphosphido)] Complexes
PublicationThis work describes a series of iron(II) phosphanylphosphido complexes. These compounds were obtained by reacting lithiated diphosphanes R2PP(SiMe3)Li (R = t-Bu, i-Pr) with an iron(II) β-diketiminate complex, [LFe(μ2-Cl)2Li(DME)2] (1), where DME = 1,2-dimethoxyethane and L = Dippnacnac (β-diketiminate). While the reaction of 1 with t-Bu2PP(SiMe3)Li yields [LFe(η1-Me3SiPPt- Bu2)] (2), that of 1 with equimolar amounts of i-Pr2PP(SiMe3)Li,...

Rapana venosa consumption improves the lipid profiles and antioxidant capacities in serum of rats fed an atherogenic diet
PublicationIn the recent years, the consumption of seafood has increased. There are no results on the studies of Rapana venosa (Rv) as a supplementation to the diets. We hypothesized that Rv would increase antioxidant capacity and reduce blood lipids, based on the composition of bioactive compounds and fatty acids. Therefore, the aim of this investigation was to evaluate in vitro and in vivo actions of Rv from contaminated (C) and non-C (NC)...

Hypericum alpestre extract exhibits in vitro and in vivo anticancer properties by regulating the cellular antioxidant system and metabolic pathway of L‐arginine
PublicationConventional treatment methods are not effective enough to fight the rapid increase in cancer cases. The interest is increasing in the investigation of herbal sources for the development of new anticancer therapeutics. This study aims to investigate the antitumor capacity of Hypericum alpestre (H. alpestre) extract in vitro and in vivo, either alone or in combination with the inhibitors of the L‐arginine/polyamine/nitric oxide...

Application of H2O2 to optimize ammonium removal from domestic wastewater
PublicationThe paper presents the results of application of hydrogen peroxide (H2O2) for the optimization of the effects of ammonia nitrogen removal from domestic wastewater. The investigations were carried out at a model wastewater treatment plant consisting of a preliminary sedimentation tank and a sand filter with a horizontal flow of wastewater at a constant hydraulic load of 1.44 L/day. The efficiency of ammonia nitrogen removal was...

In Vitro Studies on the Relationship Between the Antioxidant Activities of Some Berry Extracts and Their Binding Properties to Serum Albumin
PublicationThe aim of this study was to investigate the possibility to use the bioactive components from cape gooseberry (Physalis peruviana), blueberry (Vaccinium corymbosum), and cranberry (Vaccinium macrocarpon) extracts as a novel source against oxidation in food supplementation. The quantitative analysis of bioactive compounds (polyphenols, flavonoids, flavanols, carotenoids, and chlorophyll) was based on radical scavenging spectrophometric assays...

Antioxidant activities and bioactive components in some berries
PublicationThe objective of this study was to evaluate the antioxidant and binding effects of gooseberry, a less-stud-ied berry, and to compare with blueberry and cranberry in the model of interaction with human serum albumin (HSA). The relationship between the scavenging properties of dietary polyphenols of the selected berries and their affinities for HSA were investigated by fluorescence anal- ysis. In order to perform the extraction and...

Antimicrobial and Antiproliferative Coatings for Stents in Veterinary Medicine—State of the Art and Perspectives
PublicationMicrobial colonization in veterinary stents poses a significant and concerning issue in veterinary medicine. Over time, these pathogens, particularly bacteria, can colonize the stent surfaces, leading to various complications. Two weeks following the stent insertion procedure, the colonization becomes observable, with the aggressiveness of bacterial growth directly correlating with the duration of stent placement. Such microbial...

Strumieniowy generator wirów wzdłużnych - mechanizm działania i zastosowanie do sterowania przepływem
PublicationPraca dotyczy analizy wirów wzdłużnych generowanych przy pomocy strumienia (strugi) wydmuchiwanego do warstwy przyściennej przez otwór w ścianie. Interakcja wypływającego strumienia z przepływem wzdłuż ściany prowadzi do tworzenia się ukierunkowanego wiru, który może być wykorzystany do oddziaływania na strukturę przepływu oraz rozkład naprężeń wzdłuż przepływu za generatorem. Strumieniowe generatory wirów wzdłużnych są alternatywnym...

istota zamieszkiwania: relacje [nie]codzienne Biomorfizm w poszukiwaniach formuły domu. Między formą a bezformiem schronienia. wystawa indywidualna cykl rzeźbiarski: 10 zestawów obiektów | glina suszona
PublicationDom formę posiadać może, nie musi. Czasem dom jest tworem abstrakcyjnym. Lokuje się w wyobraźni, we wspomnieniach, regułach, opisie, obrazie. Paradoksalnie zatem, dom formy nie potrzebuje dla istnienia. Zazwyczaj jednak to o jego fizyczność chodzi. Potrzebny jest dom namacalny. Dom chroniący. Tak podpowiada ludzka fizyczność. Nasza egzystencja wymaga obudowy, schronienia, miejsca przechowywania, stref wydzielonych dla wykonywania...
