Atoms confined by very thin layers
(American Institute of Physics, 2014)
The Hamiltonian of an atom with N electrons and a fixed nucleus of infinite mass between two parallel planes is considered in the limit when the distance a between the planes tends to zero. We show that this Hamiltonian ...
DEVELOPMENT OF A CUTTING TOOL FOR COMPOSITES WITH THERMOPLASTIC MATRIX
(MM Publishing, 2013)
Fibre reinforced thermoplastic composites (FRTC) are becoming an increasingly important material for a wide range of applications. Thus, the demand for high performance tools for machining of this material is increasing. ...
Hydrological and thermal regime of a thin green roof system evaluated by physically-based model
(Elsevier, 2020)
Green roofs, as an element of the green infrastructure, contribute to the urban heat island effect mitigation and the urban drainage outflow reduction. To achieve the desired functions, it is essential to understand the ...

Utilization of recycled plastic for plastic-based concrete
(IOP Publishing Ltd, 2019)
The environmental aspects of sustainable development in the construction industry consist in the utilization of secondary raw materials in design and construction of new structures. Recycling of waste plastics reduces ...
Gold film over SiO2 nanospheres-new thermally resistant substrates for surface-enhanced Raman scattering (SERS) spectroscopy
(MDPI AG, 2019)
Surface-enhanced Raman scattering (SERS) sensors are constructed from metallic plasmonic nanostructures providing high sensitivity and spectral reproducibility. In many cases, irradiation of the SERS substrate by the laser ...
ИСПЫТАНИЯ НОВОЙ АЛЬТЕРНАТИВНОЙ ЭЛЕКТРИЧЕСКОЙ ПЕЧИ ДЛЯ ОБЖИГА ВЕРМИКУЛИТОВЫХ КОНЦЕНТРАТОВ
(Tomsk Politechnic University, 2018)
Одним из представителей георесурсов, нашедших широкое применение в различных сферах промышленности, является вермикулит. После обжига концентратов обогащенных вермикулитовых руд в пламенных печах получают вспученный ...
Micro Hydro Power for Off Grid Electrification: A Case Study of Hhaynu River - Mbulu,Tanzania
(Czech Section of the IEEE VUT, 2018)
Designing of Hydro Power Plant needs reliable water throughout the year. Determining amount of water in the stream/river is important step before implementing HEP project due to recent demand in irrigation. Two methods of ...
Single photon detector package with sub-picosecond limiting precision and stability
(Elsevier Science, 2018)
We are presenting the results of research and development of a new active quenching and gating electronics for single photon avalanche detector. The goal of this work was to improve a detector package for laser time transfer ...
Material Properties of Thin UHPC Slabs Used for Timber-Concrete Composite Bridge
(Canadian Society for Civil Engineering, 2019)
This paper deals with the material properties of Ultra High Performance Fiber Reinforced Concrete (UHPFRC or UHPC) and especially focuses on bending tests executed for the development of bridge deck segments for an innovative ...
