We investigate experimentally metal-insulator-silicon-insulator-metal (MISIM) waveguides that are fabricated by using fully standard CMOS technology. They are hybrid plasmonic waveguides, and they have a feature that their insulator is replaceable with functional material. We explain a fabrication process for them and discuss fabrication results based on 8-inch silicon-on-insulator wafers. We m...

In metallurgy the quality of the liquid metal has the biggest influence on the quality of the final products. The amount of metallic and non-metallic impurities has great impact on the consecutive stages of technological processes such as: casting, plastic working, heat treatment, etc. That is why the refining process is considered to be one of the most important parts of the basic technologica...

Due to the alarming spread of resistance to classic antimicrobial agents, innovative therapeutic methods to combat antibiotic-resistant bacterial pathogens are urgently required. This minireview examines the enhancement of antibiotic efficacy by their combination with new antimicrobials, such as plant-derived compounds, metal ions and nanoparticles and bacteriophage lytic enzymes. The mechanism...

The paper presents the results of theoretical and practical research dealing with the determination of the effects of noise on workers in an industrial environment. The ergonomic coefficient Ker, modified by the novel method presented in this paper, has been used as a measure for the effect of noise on workers. The new method has been tested on various workplaces in metal working industry. A co...
