Recycling of solar photovoltaic panels
Šperlich, Antonín
2023 - Czech Long-term trends show an increasing installed capacity of solar photovoltaic power plants. However, this is also associated with a large production of discarded panels. It is estimated that by 2050 there will be between 60 and 80 million tonnes of waste panels worldwide. Such large amounts of waste can be an \ninteresting source of valuable materials, but also need to be recycled for environmental reasons. The aim of this paper is to describe the possibilities of recycling panels and using them to build a real recycling line. Dlouhodobé trendy ukazují zvyšující se instalovanou kapacitu solárních fotovoltaických elektráren. S tím je však také spojena velká produkce vyřazených panelů. Odhadované množství odpadních panelů se předpokládá mezi 60 a 80 miliony tun celosvětově okolo roku 2050. Takto velké objemy odpadů mohou tvořit zajímavý zdroj cenných látek, ale také nutnost recyklace kvůli životnímu prostředí. Příspěvek má za cíl popsat možnosti recyklace panelů a jejich využití ke stavbě reálné recyklační linky. Keywords: recycling; solar photovoltaic panels; technology design Available in a digital repository NRGL Recycling of solar photovoltaic panels

Analytical Derivatization for Identification of Electrochemical Oxidation Products of Fentanyls
Barták, P.; Skopalová, J.; Jerga, R.; Štolbová, D.; Navrátil, Tomáš; Langmaier, Jan
2023 - Czech Analytical derivatization and GC-MS analysis were employed for the identification of main\nproducts from the electrochemical oxidation of fentanyl derivatives. Chemical derivatization\nprovides proof of the chemical reactivity of functional groups in oxidation products and serves\nfor the chemical conversion of target compounds into the second series of derivatives to confirm\nthe identification of particular products. Using the direct GC-MS analysis of oxidation products,\nderivatization of aldehydes with cysteamine and derivatization of amides by acidic hydrolysis\nand subsequent reaction with ethylchloroformiate, phenylacetaldehyde, and Nphenylpropanamide\nwere unambigously identified as oxidation products from fentanyl,\nthiophen-2-ylacetaldehyde, and N-phenylpropanamide from sufentanil, and\nphenylacetaldehyde and 2-furanilid from furanylfentanyl. Analytická derivatizace a plynová chromatografie s hmotnostní spektrometrií se osvědčily jako\nvhodné nástroje pro identifikaci oxidačních produktů a řešení reakčního mechanismu\nelektrochemické oxidace fentanylů a dalších opioidů. Provedené experimenty potvrdily\npřítomnost fenylacetaldehydu a N-fenylpropanamidu v roztoku po elektrochemické oxidaci\nfentanylu. V případě sufentanilu byl jako odpovídající aldehydický produkt prokázán thiofen-\n2-ylacetaldehyd a v případě furanylfentanylu byl jako amidický produkt prokázán zcela\nanalogicky 2-furanilid.

Methodology for co-cryostorage of virus isolates in their host plants and relevant data

2023 - English Currently, the nursery production of plant material emphasizes the production of healthy, virus-free material. For this reason, it is necessary to have reference plant materials in which the virus is present. Some types of viruses are difficult to maintain outside the plant host. Because of the potential transmission to outdoor plantings, it is necessary to keep infected plants in special cultivation areas, and net-houses, which brings considerable financial and labour costs. Therefore, a methodology was developed in which the virus status in plant material is analysed, the infected material can be stored using cryopreservation in liquid nitrogen and then regenerated in vitro, and relevant data in GeneEver cryobox can be stored.
