Repairs of cement concrete pavements are among the most demanding technological operations in road construction and therefore require increased attention. Repairs of less damaged cement concrete pavements are usually made using plastic mortars, epoxy and polyester resins or special materials. The economics of the repair, or the strengthening of damaged cement concrete pavements, is tied to the technical and technological problems of interaction with asphalt layers. Thin reinforced cement concrete slab is a method ...

We studied polyimide and lavsan films after exposure to varying doses of electron irradiation, mechanical loading, and temperature. It was found that at the first stage of mechanical loading, up to 1 MPa. A similar sharp increase in the relative elongation of the films by 3% was observed. This is due to the rotation of globules and the straightening of macromolecular chains in the material along the direction of the applied load. The dependence of the absorption coefficient on the wavelength per unit path length i...

Oxidoreductase enzymes play a key role in modern biotechnology due to their high specificity and ability to catalyze redox processes under mild conditions. They are used in environmental monitoring, biosensor development, and fine organic synthesis. However, their practical use in their native form is limited by their low stability, sensitivity to environmental changes, and the inability to re-extract from the reaction mixture. Immobilizing enzymes on various carriers can solve these problems. Magnetic nanoparticl...

With the rapid growth of polymer consumption, the issue of efficient recycling and disposal of plastic waste is becoming increasingly pressing. One promising approach is thermal degradation (pyrolysis), which yields valuable hydrocarbon products [1]. Of particular interest is the recycling of polyethylene with increased thermal stability (PE-RT) with the addition of octylene-1. This material combines thermal stability, mechanical strength, flexibility, chemical resistance, and processability, making it a highly ef...

Amorphous aromatic polymers synthesized by the knitting method are promising supports in catalysis, since they have high porosity (up to about 1000 m2/g) and can be synthesized by the simple one-step procedure using a variety of available aromatic monomers [1-4]. In catalysis, the stability of active phase is typically discussed, while the stability of polymeric support remains outside the scope. At the same time, many reactions require high temperature or application of strong acids or bases. In this work, a seri...

The highest Fe and Cu were in biochar from p...

The foundry industry is a major producer of industrial waste, with used foundry sands (UFS) representing the largest share. While bentonite-bonded sands can be reused multiple times, sands with organic binders are typically single-use and are often landfilled due to limited regeneration capacity. Their valorization in construction materials represents an important pathway toward circular economy. This study evaluates the use of UFS from three different foundries, including bentonite- and furan-bonded systems, as p...

The COVID-19 pandemic significantly disrupted traditional higher education practices, particularly in GeoScience disciplines where fieldwork, site observation, and direct environmental interaction are essential components of learning. Travel restrictions, social distancing measures, and limited access to outdoor learning environments accelerated the adoption of digital teaching methods and created strong demand for alternative experiential learning models. Among these, Virtual Field Trips (VFTs) emerged as an inno...

This paper proposes the concept of the virtual perimeter as an innovative approach for determining the average velocity of ventilation flow in tunnels. Average velocity is a fundamental parameter that defines volumetric and mass flow rates, energy losses, and thermal regimes. Classical methods, based on multipoint measurements with anemometers, are difficult to apply in large tunnels and, in many cases, practically impossible. The virtual perimeter identifies the zone of the tunnel’s cross-section where the loca...
