Oxygen Transfer from Trimethylamine N-oxide to CuI Complexes Supported by Pentanitrogen Ligands

2020

[N,N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine] ( L 1 ) and [N,N-bis(2-quinolylmethyl)-N-bis(2-pyridyl)methylamine] ( L 2 ) were employed to prepare Cu II  and Cu I  complexes for spectroscopic and structural characterization. [ L 1 Cu II (H 2 O)](NO 3 ) 2 and [ L 2 Cu II (NO 3 )]NO 3 have Jahn-Teller distorted octahedral geometries, and give rise to isotropic EPR spectra in frozen solution. [ L 1 Cu I (CH 3 CN)]OTf and [ L 2 Cu I (CH 3 CN)]OTf have distorted trigonal bipyramidal and tetrahedral solid-state structures, respectively. The N-donors display labile behavior in solution, based on variable-temperature 1 H NMR studies. Addition of trimethylamine N-oxide (Me …

Environmental Organic Photochemistry: Advances and Perspectives

2013

This review is a survey of recent advances in environment related aspects of organic photochemistry. Besides presenting gen- eral concepts, the manuscript is mainly focused on the photoreactivity of natural organic matter, and on the photochemistry of anthropo- genic substances under natural light irradiation.

PHOTOOXIDATION BEHAVIOR OF POLYPROPYLENE NANOCOMPOSITES WITH MODIFIED HALLOYSITE

2017

The photooxidation behaviour of polymer nanocomposites depends on the photooxidation of the matrix, but also on the possible interactions with the nanoparticles. In this work, the effect of halloysite modified nanoparticles on the photooxidation of a polypropylene matrix has been investigated.

Fotoutlenianie siarki w obecności wybranych diftalocyjanin lantanowców

2016

Zagadnienie odsiarczania jest problemem zarówno w przemyśle jak i w ochronie środowiska naturalnego, gdyż związki siarki stanowią zagrożenie dla organizmów żywych. Podjęto więc badania nad możliwością wykorzystania fotoaktywnych kompleksów ftalocyjaniny jako potencjalnych aktywatorów w procesie utleniania związków siarki. W pracy badano proces fotoutleniania siarki elementarnej w obecności NdPc2 oraz YbPc2 w roztworze DMF. Otrzymane wyniki wskazują, że jedynie kompleks z Yb efektywnie katalizował badaną reakcję, przy mniejszym natężeniu promieniowania UV. Okazało się, że największy wpływ na przebieg i wydajność procesu fotoutleniania ma intensywność naświetlania układu. Rodzaj użytego fotoa…

Biocompatibility and Antibacterial Properties of ZnO-Incorporated Anodic Oxide Coatings on TiZrNb Alloy

2020

In a present paper, we demonstrate novel approach to form ceramic coatings with incorporated ZnO nanoparticles (NPs) on low modulus TiZrNb alloy with enhanced biocompatibility and antibacterial parameters. Plasma Electrolytic Oxidation (PEO) was used to integrate ZnO nanoparticles (average size 12&ndash
