SMV-2023-61: Measuring systems for lithographers
Mikel, Břetislav
2023 - Czech
The contract research was focused on the development of multi-axis measuring systems using the most accurate method of measurement based on the principle of laser radiation interference. The basic reference is a laser source with a wavelength of 633 nm. Measuring systems are intended for devices requiring measurement accuracy in the order of nanometers. Smluvní výzkum byl zaměřen na vývoj víceosých odměřovacích systémů využívajících nejpřesnější způsob měření na principu interference laserového záření. Základní referencí je laserový zdroj o vlnové délce 633 nm. Odměřovací systémy jsou určeny do zařízení vyžadující přesnost měření v řádech nanometrů.

Design analysis of the heat exchanger between the primary and the intermediate circuits of the small modular reactor DAVID
Kobylka, D.; Hrubý, Jan; Kordík, Jozef; Gabriel, Dušan; Marek, René; Isoz, Martin
2023 - Czech
The report summarizes the joint results of the Department of Nuclear Reactors FNSPE, CTU and IT CAS, in the area of thermal and hydraulic calculations of the heat exchanger between the primary and intermediate circuits of the developed small modular reactor (SMR) DAVID. The assignment parameters were further specified during control days and with updated documentation. During the analysis of the initial system parameters, it was found that the original geometric configuration of the exchanger had a completely insufficient surface for heat transfer. A decision was made, several parameters were modified and based on a series of calculations using two independent simplified models, a reasonable configuration with a significantly smaller diameter of the tubes in a significantly larger number was chosen. The pressure losses on both sides of the heat exchanger are within normal ranges and will not cause problems with the construction of these circuits. Although there are differences between the results from both used models, their comparison shows that the chosen different calculation methods lead to approximately the same results and the models do not show fundamental errors.

SMV-2023-54: EM Nematodes II 2023
Hrubanová, Kamila
2023 - Czech
The aim of the contract research was the expert analysis of biological samples with the intention of describing morphological features for species classification. As part of the collaboration, chemical preparation of the samples was carried out, followed by observation of the bodies of the nematodes themselves in different positions so that individual morphological characters could be distinguished using an electron microscope. Cílem smluvního výzkumu byla odborná analýza biologických vzorků se záměrem popsat morfologické znaky pro druhovou klasifikaci. Součástí spolupráce byla provedena chemická příprava vzorků, následovalo pozorování těl samotných hlístic v různých pozicích tak, aby bylo možné rozlišit jednotlivé morfologické znaky pomocí elektronového mikroskopu.

SMV-2023-57: EM analysis of microorganisms II
Hrubanová, Kamila
2023 - Czech
The aim of the contract research was the expert analysis of microbiological samples with biotechnological significance with the intention of describing the ultrastructure of the cells, which depends on the cultivation conditions of the industrial process. The collaboration included cryogenic preparation of samples, followed by microbial microscopy using low-temperature electron microscopy (cryo-SEM), and selected samples were processed for transmission electron microscopy (TEM). Furthermore, spectroscopic measurements were performed using Raman spectroscopy. Cílem smluvního výzkumu byla odborná analýza mikrobiologických vzorků s biotechnologickým významem se záměrem popsat ultrastrukturu buněk, která se odvíjí od kultivačních podmínek průmyslového procesu. Součástí spolupráce byla provedena kryogenní příprava vzorků, následovalo mikrobů pomocí elektronového mikroskopu za nízkých teplot (cryo-SEM), vybrané vzorky byly zpracovány i pro transmisní elektronovou mikroskopii (TEM). Dále byla provedena spektroskopická měření pomocí Ramanovy spektroskopie.
