One of problems in terrain surveys in geology and archeology is sample obtaining. Among all possible complications are limits in sample volumes and masses, including possible toxicity or radioactivity and also the legal status of the samples. In his contribution, these problems are addressed by application of microsampling by surface exfoliation of geological objects and archaeologic artifacts using various tapes and subsequent analyses of the resulting samples. Among method used were both optical and electron mic...

The magnesium oxychloride cement (MOC) as an alternative to commonly used Portland cement (PC) has been intensively studied in the past decade. Compared to PC it is more environmentally sustainable and it can be considered as CO2-neutral due to the low calcination temperature of the raw materials and its ability to absorb CO2 from the atmosphere. The objective of this paper was to develop a composite material based on MOC, containing partially oxidized multi-walled carbon nanotubes (partially oxidized MWCNTs) in o...

The research of 2D carbon-based nanomaterials has become very intensive since the discovery of graphene. Many different preparation procedures of graphene and graphene derivatives have been reported. The aim of this paper was to prepare and characterize partially oxidized graphite oxides, which were prepared from nanographite by adding different amounts of potassium permanganate as an oxidizing agent. The C/O ratio was evaluated from X-ray photoelectron spectroscopy, energy dispersive spectroscopy, and elemental a...
