Hybrid sol-gel coatings based on different acrylate derivatives for protection of aluminium alloy and steel against corrosion and biofouling
The subject of the doctoral dissertation is the development of coatings with improved protection of metals against corrosion and antifouling protection on structural steel S355 and aluminum alloy AA7075. S355 is a widely used metal in the construction, while AA7075 is mostly used in the transportation industry. Although they exhibit …
Crystal structure and phase transformations in 1D nanostructures
Metal oxide and sulfide nanostructures are a versatile family of materials with wide-ranging applications, and their development remains ongoing. In nanoscience, attention is being directed towards their synthesis and further advancement, including the creating of new complex structures and morphologies. In this regard, ion-exchange reactions have emerged as a cutting-edge …
Characterization of Spirulina microalgae as a new alternative food source
A reduction in agricultural productivity associated with water scarcity and land degradation, combined with the growing world population and malnutrition highlights the need for new alternative food sources. In this challenging field, Spirulina microalgae emerges as a promising candidate thanks to its high nutritional value and beneficial effect on human …
Development and employment of untargeted and targeted tools for virus detection in the frame of water-based epidemiology
Traditional methods of studying viruses are limited in their ability to detect novel pathogens, but recent advances in high-throughput sequencing (HTS) are changing that. HTS allows researchers to probe deeply into the virome of various hosts and environments, identifying known and unknown viral species. However, a targeted approach, like quantitative …
Use of information and communication technologies, data and knowledge to increase the impact of digital environments on food choice
Food and eating environments play a crucial role in shaping consumers' food choices. As food decision-making shifts more into the digital environment, it is essential to understand the impact of this setting on consumer's dietary behaviours. Online platforms and mobile apps provide great opportunities for the promotion of healthier food …
Surface modifications of cellulose nanomaterials: mechanisms, kinetics and their applications
Synthesized in green plants, cellulose is the most abundant natural biopolymer on the planet and is thus widely available, cheap and renewable. Furthermore, its hierarchical structure allows extraction of nanosized particles in the form of cellulose nanocrystals (CNCs), obtained with hydrolysis or cellulose nanofibrils (CNFs), isolated through chemical, biological pretreatment …
Identification of indoor radio environment properties based on channel state information using machine learning approaches
Characterization of the indoor radio environment (RE) is a prerequisite for advances in the design and optimization of next-generation indoor wireless networks and for the construction of a digital twin of the building. The need for comprehensive and accurate indoor characterization will be evident in the future hyper-connected mixed real-virtual …
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 …
Interactions of azole molecules with copper ions and copper surfaces covered with chemisorbed H, O, Oh or Cl
In real environments, copper and other metal surfaces are never clean. Even during active dissolution in corrosion, they are likely to be covered with adsorbed corrosion-relevant species such as O, OH, H, and Cl. To explore the impact of such species on the bonding of imidazole, used herein as an …
Use of hydrated glass for synthesis of waste-based foamed glass
Thermal insulation materials have a strong impact on energy efficiency of buildings which are one of the main energy consumers in the EU. Thermal insulation materials are widely used and improving their properties or improving their production can therefore have a rapid impact on the efficient use of energy in …
