Reduction of CO2 emissions at firing of binders type Portland cement Marcela Fridrichová1,a, Jan Gemrich2,b, Jana Stachová1,c and Radek Magrla1,d 1Brno University of Technology, Faculty of Civil Engineering, 602 00 Brno, Veveří 95, Czech Republic 2Výzkumný ústav maltovin Praha s.r.o., Praha 5-Radotín 153 00, Na Cikánce 20, Czech Republic afridrichova.m@fce.vutbr.cz, b gemrich@vumo.cz, cstachova.j@fce.vutbr.cz, dmagrla.r@fce.vutbr.cz Key words: Portland clinker, Portland cement, clinker minerals, hydration process, fluidized bed ash, fluidized fly ash, emission CO2 Abstract: Presented article deals with burn of raw admixtures with low content of carbon component for Portland cement burn.
Because the firing of Portland clinker is realized at higher temperatures, the constitution of raw mixture samples was designed by calculation from chemical composition of entrance materials to chosen values of single modules, resp. levels of carbonation by lime: Sample S1: triple-component from bed ash, limestone and Fe-correction; pbw of components: bed ash: gypsum: Fe-correction= 1:1,65:0,0005; phase composition according to Bogue: 64 % C3S, 18 % C2S, 8 % C3A and 7 % C4AF.
From done adjustments it has resulted that for sufficient kinetics of creation all clinker materials including the most important mineral alite, 3CaO.SiO2, it is necessary to add at least that amount of thermal energy, which meets modes 1400oC /5 hours, resp. 1450oC /3 hours with optimum 1450oC/ 5 hours in conditions of laboratory firing in superkanthal furnace.
Initiate differences in literature documented and confirmed mentioned fact about selective grinding of clinker materials.

Synthesis of nanostructured absorber materials is of great technological interest because photovoltaic devices employing nanostructures display higher values of energy conversion efficiency compared to conventional thin-film devices.
In both approaches, in order to obtain CZTSe nanostructures, a sacrificial template was necessary, implying material and time consumption.
We have found that not only current waveform controls morphology of nanostructures, but a key role has also supporting electrolyte.

Effects of Radio-Frequency Power and Deposition Pressure on Structures and Properties of Silicon-Rich Silicon Nitride Thin Films Sun Jiaxina, Zhou Bingqingb*, Gu Xinc Key Laboratory of Physics and Chemistry for Functional Material, College of Physics and Electron Information, Inner Mongolia Normal University, Huhhot 010022, China a2637255253@qq.com, bzhoubq@imnu.edu.cn, c1558910050@qq.com Keywords: plasma enhanced chemical vapor deposition, silicon-rich silicon nitride film, RF power, deposition pressure, microstructure.
The substrate material was N-type silicon wafer (double-polished) and Corning 7059 glass wafer.
It can be seen from the diagram that the optical band gap width of the two sample groups were both between 2.0-2.5eV, which indicated that the deposited samples were silicon-rich silicon nitride thin film materials.
