Properties of aprotic electrolytes for lithium-ion accumulators
Staněk, Vladimír ; Máca, Josef (referee) ; Frk, Martin (advisor)
The present work deals with the properties of suitable electrolytes for lithium-ion batteries. The first part described in the current issue of electrolytes for lithium-ion batteries, types of solvents and their properties and methods of measurement properties. The second part is devoted to the measurement of the properties of solvents and electrolytes such as relative permittivity, density and viscosity. Measurement of relative permittivity was focused on the measurement of the solvent mixture with varying the percentage of the solvent. Viscosity and density were measured on a solvent with a lithium salt added (final electrolyte).
Studium dynamiky živých lidských buněk v odezvě na běžné kontaminanty vod s cílem vývoje citlivého specifického analytického postupu
KOŠEK, Jan
The bachelor thesis is devoted to testing the toxicity of chemical substances. In the current chemical and pharmaceutical industry, thousands of new substances are produced annually, which brings about the need to ensure sufficient consumer safety and environmental protection. In vitro testing is becoming an increasingly important research tool in this issue. This work verifies the theoretical foundations and proposes an algorithm developed by Lonhus et al. from the Laboratory of experimental complex systems in Nové Hrady and its possible future applications in in vitro testing. This new approach uses the principles of microrheology and tracks Speed-Up Robust Features (SURF) in a digital image and converts them into vectors of trajectories of intracellular mass particles. Microrheology is a relatively new field of research in life sciences and deals with the study of flow and deformation of materials at the microscopic level. The algorithm separates two main components of the movements inside the cells: direct movement of organelles as larger particles and random Brownian motion. The advantage of this method is its potential of easy use and sensitivity. The method makes it possible to obtain important primary information about the effect of chemical substances on cell cultures.
