1,3,5-Trichloro-2,4,6-trifluorobenzene and 1-bromo-3,5-dichloro-2,4,6-trifluorobenzene undergo selective defluorination on heating in dimethylsulfoxide with sodium azide to form 1,3,5-triazido-2,4,6-trichlorobenzene and 1,3,5-triazido-2-bromo-4,6-dichlorobenzene in high yields. The azidation of ...

Copper (II) acetylacetonate was immobilised directly onto two clays, laponite (Lap) and K10-montmorillonite (K10), and after their amine functionalisation with (3-aminopropyl)triethoxysilane (APTES). All the materials were characterised by nitrogen adsorption isotherms at −196 °C, elemental ana...

Metal acetylacetonates are often used as precursors for the deposition of oxides in CVD or ALE experiments. The thermal stability and the vapour/sublimation pressures of such compounds are of fundamental importance for reproducible depositions. We have started a program to study the long term th...

Gas-quenching has been demonstrated to be a robust and reliable method for fabricating perovskite solar cell (PSCs) and is a technique for large area and large-scale production. Although additive engineering has been used to improve various perovskite fabrication methods, it is yet to be utilise...

The mixed ligand complexes [K2(acac)2(H2O)]∞ (I), [K2(acac)2(phen)(H2O)]∞ (II), [Na(acac)(H2O)]∞ (III), [Na3(acac)3(iPrOH)]∞ (IV), [Na3(acac)3(Py)]∞ (V) and [Na2(acac)2(phen)]∞ (VI) (Hacac = pentane-2,4-dione; phen = 1,10-phenanthroline; iPrOH = iso-propanol; Py = pyridine) were synthesize...

Glyphosate (GLY) is considered the most used herbicide in the world and has been associated with several environmental contamination risks. Despite being partially degraded by soil microorganisms, its residues can negatively affect the growth of valuable non-target plants. Thus, there is a need ...

Salt stress disturbs redox homeostasis by perturbing equilibrium between generation and removal of reactive oxygen species (ROS), which alters the normal metabolism of plants through membrane damage, lipid peroxidation and denaturation of proteins. Salicylic acid (SA) seed priming and arbuscular...

Soil salinity is one of the most important problems of crop production in estuarine and coastal zones. Improvement in salt tolerance of major food crops is an important way for the economic utilization of coastal zones. This study proved that the application of salicylic acid (SA) improved the g...

BackgroundCatheter-related bloodstream infection (CR-BSI) is one of various complications related to hemodialysis (HD). As a result of the high rate of infection, the use of lock solutions for the prevention of CR-BSI has been studied. However, adverse effects of lock solution, such as increased...

SummaryBackground & aimsCentral venous access device (CVAD)-related complications, such as central-line associated bloodstream infections (CLABSIs), CVAD-related venous thromboses (CRVTs) and –occlusions frequently occur in home parenteral nutrition (HPN) patients. A preventive strategy to decr...

The main objective of this study was to assess the photoactive properties of iron-doped silica xerogels under solar radiation. For this purpose, silica xerogels (XGS) were doped with different doses of Fe(III) by the sol-gel method. Tinidazole (TNZ) was considered as model compound for the degra...

The in vitro and in vivo antihelmintic activity of cobalt(II), copper(II) and zinc(II) coordination compounds of tinidazole (tnz) were investigated in cultivated spotted rose snapper, infested with dactylogyrid monogeneans. The tinidazole coordination compounds [Co(tnz)2Cl2], [Co(tnz)2Br2], [Cu(...

ObjectiveThe purpose of this study was to compare the efficacy of 2 different doses of tinidazole with metronidazole for the treatment of bacterial vaginosis and to compare the side effects of the drugs.

Three new 1,2-dihydro-1-oxabenz[a]azulen-2-one derivatives, 1a (R1=H, R2=Me), 1b (R1=H, R2=Ph), and 1c (R1=COOEt, R2=Me), have been synthesized by the reaction of 2-hydroxyazulene (2a) and its 1-ethoxycarbonyl derivative 2b with ethyl acetoacetate (3a) or ethyl benzoylacetate (3b) in the presenc...

A simple new method for methoxylation of 7-membered ring of 1,2,3-trisubstituted azulenes via electrooxidation is reported. It could be useful in preparing 2,4- and 2,6-azuloquinone analogs.

It was found that intrifluroacetic acid, 2-methyl 8H-3-oxaheptalen-8-one was transformed into 2-hydroxy-3-methyl-7H-benzocyclohepten-7-one and 1-formyl-6-hydoxy-2-methylazulene, whereas 2,4-dimethyl-8H-3-oxaheptalen-8-one was under the same conditions into 1-acetyl-2-methyl-6-hydroxyazulene. 2-P...

The reaction products of ozone with pyrene and benz[a]anthracene absorbed on azelaic acid particles under the pseudo-first-order reaction conditions have been investigated with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer (VUV-ATOFMS). The pyrene and benz[a]anthr...

The pathway for the ozonolysis of benz[a]anthracene (BaA) (ACS standard named), a polycyclic aromatic hydrocarbon (PAH), has been described in this paper. BaA was dissolved in a 90% acetonitrile:water (v/v) mixture to achieve an initial concentration of 1 mM. The ozonolysis of BaA was evaluated ...

Benz(a)anthracene (BA) is an ubiquitous environmental pollutant of polycyclic aromatic hydrocarbon’s (PAHs) family. We showed superoxide (O2−) catalyzed BA photo modification and apoptosis in HaCaT keratinocytes under sunlight exposure. O2− generation was confirmed by quenching through superoxi...
