Investigation of biological and photochemical treatment of municipal landfill leachates
PublikacjaW pracy przedstawiono rezultaty badań charakterystyki oraz efektywności foto- oraz biodegradacji odcieków z dwóch składowisk komunalnych w północnej Polsce. Celem pracy było zbadanie efektywności oczyszczania w systemie UV, UV/H2O2 oraz możliwości biologicznego oczyszczania odcieków metodą osadu czynnego. Stosowanie metody kombinowanej (UV/H2O2/osad czynny) pozwoliło na uzyskanie lepszej efektywności oczyszczania (98% spadek wartości...

Photochemical degradation of xylene.
PublikacjaBadano degradację ksylenu w układzie UV/H2O2 z wykorzystaniem 500ppm emulsji ksylen-woda oraz 100ppm roztworu ksylenu. Zbadano wpływ ilości H2O2 na efektywność degradacji. Najkorzystniejsza dawka wynosiła 0,01%v/v powodując 66%degradację ksylenu w emulsji oraz 100% degradację ksylenu w roztworze wodnym po 30 min. naświetlania.

Photochemical degradation of pollutants in aqueous phase
PublikacjaTlenek tytanu (IV) wykorzystywany jest jako fotokatalizator służący oczyszczaniu wody i powietrza z wykorzystaniem tzw. powierzchni samoczyszczających się. Zastosowanie fotodegradacji w obecności TiO2 uzasadnione jest przede wszystkim do usuwania substancji toksycznych i/lub trwałych i jednocześnie występujących w małych stężeniach oraz jeżeli w procesie fotodegradacji można wykorzystać promieniowanie słoneczne. Wyniki badań wskazują,...

Optimization of Hydrogen - Evolving Photochemical Molecular Devices
PublikacjaA molecular photocatalyst consisting of a RuII photocenter, a tetrapyridophenazine bridging ligand, and a PtX2 (X=Cl or I) moiety as the catalytic center functions as a stable system for light-driven hydrogen production. The catalytic activity of this photochemical molecular device (PMD) is significantly enhanced by exchanging the terminal chlorides at the Pt center for iodide ligands. Ultrafast transient absorption spectroscopy...

Photochemical Rearrangement of a 19-Membered Azoxybenzocrown: Products and their Properties
PublikacjaThe preparation and characterization of products of the chemical and photochemical rearrangements of a 19-membered o,o'-azoxybenzocrown were presented. In photochemical rearrangement, besides expected product i.e. 19-membered o-hydroxy-o,o'-azobenzocrown (19-o-OH), obtained under defined conditions with 75% yield, also other macrocyclic products were isolated and identified, namely: 19-membered p-hydroxy-o,o'-azobenzocrown (19-p-OH),...

Photochemical and thermal reaction of intermediates in the phenylnitrene rearangment inside a hemicarcerand
PublikacjaBroadband irradiation (λ > 320 nm) of hemicarceplex H1 between −74 °C and −84 °C, produces encapsulated didehydroazepine (2), triplet phenylnitrene (3PN), 2-azabicyclo[3.2.0]hepta-1,3,6-triene (6), and 4-azaspiro[2.4]hepta-1,4,6-triene (7). The highly strained anti-Bredt imine 6 is formed from 2 via a photochemical four-electron electrocyclization. Under the irradiation conditions, 6 rearranges further to azaspirene 7. In addition,...

Synthesis and hydrogen evolving catalysis of a panchromatic photochemical molecular device
PublikacjaA dinuclear hydrogen evolution photocatalyst [(tbbpy)2Os(tpphz)PtI2](PF6)2 (tbbpy = 4,4′-tert-butyl-2,2′-bipyridine; tpphz = tetrapyrido[3,2-a:2′,3′-c:2′′,3′′-h:2′′′,3′′′-j]phenazine) is synthesized in order to make use of the broader range of visible light absorption mitigated by the osmium center. In a first step, the activity of the complex for hydrogen evolution is investigated by evaluating the role of different electron donors...

The influence of food phytochemicals on cyclic phosphodiesterase 4 (PDE4) activity
PublikacjaCyclic phosphodiesterase 4 (PDE4) belongs to family of cyclic phosphodiesterases, which are expressed predominantly in inflammatory cells, airway smooth muscles, cardiovascular tissues and brain. Inhibitors of this family of enzymes found medicinal applications as antidepressants, antiinflamatory drugs (mainly in airway diseases) or antiasthmatics (Ibudilast). PDE4 inhibitors are also being tested for preventing the development...

Phytochemical screening and biological evaluation of Greek sage (Salvia fruticosa Mill.) extracts
PublikacjaThis study explores the influence of extraction solvents on the composition and bioactivity of Salvia fruticosa extracts. Ultrasound-assisted extraction with water, ethanol and their mixtures in variable proportions was used to produce four different extracts. An untargeted UPLC/MS‑based metabolomics was performed to discover metabolites profile variation between the extracts. In the analyzed samples, 2704 features had been detected,...

The influence of plant protection by effective microorganisms on the content of bioactive phytochemicals in apples
PublikacjaThe phytochemicals of two apple cultivars (Yellow Transparent and Early Geneva) protected in two ways, conventionally with chemical pesticides or by effective microorganisms (EM), were compared. Two types of components were determined: lipids synthesised constitutively and generated via inducible pathways polyphenols along with antioxidant activity and profiles. The antioxidant activities assessed with ABTS, DPPH and Folin–Ciocalteu...
