Assessment of dimethyl sulphide odorous emissions released during the underground coal extraction in coal mine Velenje
Underground coal extraction at Coal Mine Velenje occasionally gives rise to odour complaints from local residents and irritates and disturbs the miners at work in the mine. This work describes a robust quantification of odorous emissions of mine sources and a model-based analysis aimed to establish a better understanding of …
Spatial and energy distributions of sputtered atoms in thin film deposition techniques
The sputtering yield, the spatial distribution of the sputtered atoms, the energy distribution and the average energy of the sputtered atoms are important for numerous deposition techniques, as they determine the microstructure and the physical properties of the thin films. Using SRIM (Stopping and Range of Ions in Matter) simulations, …
Temperature fractionation of mercury in the cement production process
Cement production is one of the main contributors to mercury emissions in to the atmosphere. Many national and international legal i nstruments aim to control and reduce Hg emissions. Hg enters the cement production process as an impurity in fuels and raw materials, with the latter being the main source …
Hidrothermal topochemical conversion of Bi4Ti3O12 nanoplatelets for formation of functional heterostructural perovskite titanates
In the view of designing new nanostructured materials and tailoring their functional properties, understanding the nucleation and crystal growth mechanisms is becoming increasingly important. Nowadays, one of the most addressed scientific and social problems are those facing energy shortage and global warming. People started to realize the value and importance …
Investigation of the environmental acceptability of geotechnical composites, made from different recycled materials investigation of the environmental acceptability of geotechnical composites, made from different recycled materials
Current and especially past industrial and mining activities, including underground and open pit mining, have often resulted in soil pollution that has become a global and alarming environmental problem. Among contaminants, heavy metals and metalloids are under environmental scrutiny due to their potential toxicity, persistence, and because they can be …
New methods for the determination of elemental composition and simple phenolic compounds in atmospheric particulate matter
Air pollution is an inevitable problem that modern society has to face today, with particulate matter (PM) being the most dangerous part of it, threatening human health and the environment. Not all PM particles, however, are equally harmful, since the dangerous potential depends on their size and chemical composition, which …
Optimization and application of MeV time-of-flight secondary ion mass spectrometry in the standard and low primary ion beam energy mode
Time-of-flight secondary ion mass spectrometry using MeV ions (MeV ToF SIMS) has been around for a few decades as a reliable, surface-sensitive method for the detection of molecular ions having masses up to 1000 Da. It provides excellent lateral resolution of a few μm for imaging of organic samples, making …
Time-efficient method for monitoring electrochemical energy conversion systems
According to the EU’s Green Deal plan, one of the main objectives for the EU is to become a net-zero greenhouse emission society by 2050. Achieving this goal requires advancements across many areas ranging from energy production, conversion, distribution and energy storage where the key role is taken by the …
Optical emission spectroscopy as a tool for monitoring cold atmospheric pressure plasma processes
Non-equilibrium atmospheric pressure plasmas are used in many areas, such as food and agriculture, plasma medicine, plasma surface modification, material synthesis and deposition. Because of their versatility, many plasma setups have been developed. Of greater interest are those that operate at atmospheric pressure, like atmospheric pressure plasma jets (APPJs). Regarding …
Characteristics of gaseous plasma in a large low-pressure reactor
The scientific backgrounds of technologies involved in the production of headlamps for the automotive industry are elaborated in this thesis. The experimental work was performed using an industrial plasma reactor with a volume of approximately 5 m3. The reactor enables three different operations, i.e., plasma pretreatment of workpieces made from …
