Chemical investigation of the Al2O3 ultra-thin films
Open Research DataUltra-thin layers of oluminum oxide (Al2O3) were deposited by ALD method. Atomic layer deposition provides precise thickness control down to a single atomic layer. The precursors used were trimethylaluminum (Sigma-Aldrich) and purified water. The deposition of the atomic layer was carried out at 200 °C. Samples with a thickness of 2 and 8 nm of alumina...

Chemical pollution and toxicity of water samples from stream receiving leachate from controlled municipal solid waste (MSW) landfill
PublicationThe present study was aimed to determine the impact of municipal waste landfill on the pollution level of surface waters, and to investigate whether the choice and number of physical and chemical parameters monitored are sufficient for determining the actual risk related to bioavailability and mobility of contaminants. In 2007–2012, water samples were collected from the stream flowing through the site at two sampling locations,...

From ashes to porous hierarchical nanocarbon electrode: Upcycling secondary waste materials through self-catalytic chemical vapour deposition
PublicationMetal and metal oxide particles are abundant in various ash-based wastes. Utilizing these as catalyst sources for the fabrication of carbon nanomaterials could present a valuable approach to reduce our reliance on non-renewable and costly catalyst sources, thereby facilitating large-scale nanomaterial production. In this context, secondary waste materials (SWMs) are by-products resulting from the (complete or partial) combustion...

Porównanie przebiegu enzymatycznej hydrolizy oleju rzepakowego i strukturyzowanych lipidów zawierających kwas behenowy. The comparision on the course of enzymatic hydrolysis of rapeseed oil and structured lipids containing behenoic acid.
PublicationPorównywano przebieg enzymatycznej hydrolizy oleju rzepakowego i strukturyzowanych lipidów zawierających kwas behenowy (C22:0). Hydroliza prowadzona była w obecności lipazy trzustkowej, w warunkach stymulujących proces trawienia. Stwierdzono, że olej rzepakowy hydrolizowany jest znacznie szybciej niż strukturyzowane lipidy z kwasem behenowym.
