Proč už nepodporujeme prohlížeč Internet Explorer

Prohlížeč Internet Explorer již nepodporujeme a také důrazně nedoporučujeme, protože dlouhodobě funguje bez zásadních aktualizací, vylepšení a podpory. Obsahuje řadu závažných bezpečnostních rizik, které mohou způsobit únik citlivých informací a vašich osobních dat. Nehledě k tomu, že prohlížení a práce s webovými stránkami je v něm pomalejší až o 50 % v porovnání s ostatními prohlížeči.

Které prohlížeče tedy používat a kde si je můžete stáhnout?

Změna prohlížeče je jednoduchá, nezabere vám moc času a my vám s ní pomůžeme. Nachystali jsme pro vás seznam doporučených prohlížečů.

Vyberte si prohlížeč a klikněte na jeho název. Otevře se vám stránka, na které si prohlížeč můžete bezpečně nainstalovat.

TIP: Klidně si můžete nainstalovat všechny a vyzkoušet si, jak se vám s nimi pracuje.

A nebojte se, že změnou přijdete o všechny záložky, historii a uložená hesla. Můžete si je totiž jednoduše přenést. Postup pro dva nejpoužívanější prohlížeče přidáváme.

Doporučené prohlížeče:

Mozilla Firefox je výkonný, stabilní a bezpečný prohlížeč. Záložky a další data si můžete přenést podle návodu zde.
https://www.mozilla.org/cs/firefox/
https://support.mozilla.org/cs/kb/import-zalozek-dalsich-dat-z-internet-exploreru-ne

Google Chrome je rychlý, jednoduchý a bezpečný prohlížeč. Podívejte se na návod, jak přenést záložky a ostatní informace do Google Chrome.

Jak na výrobu čistých optických izomerů?

19. 3. 2025 Jan Kříž

Pro opticky aktivní látky je charakteristické, že pouze jeden z optických izomerů vykazuje požadované vlastnosti a účinky, zejména pak účinek terapeutický, zatímco druhý izomer takové vlastnosti nevykazuje vůbec nebo jenom ve velmi omezené míře, či dokonce vykazuje účinky negativní. Výrobní postupy těchto látek často poskytují jako výsledný produkt směs obou optických izomerů. Vzniká tak naléhavá potřeba mít k dispozici alternativní technologie produkující pouze jeden (čistý) optický izomer produkované látky. Skupina autorů z Fakulty chemicko-inženýrské VŠCHT Praha a Ústavu chemických procesů AV ČR vedená prof. Michalem Přibylem k tomuto tématu publikovala na základě pozvání prestižního časopisu Catalysis Reviews (IF 2020: 20,217) přehledový článek „Microreaction and membrane technologies for continuous single-enantiomer production: A review“. Publikace shrnuje současný stav poznání a technologií v oblasti produkce čistých enantiomerů, které jsou založeny na využití mikro-reaktorů, především pak enzymových, kombinovaných s membránovými separačními technikami. Mikro-reaktory umožňují zejména snadnou a efektivní kontrolu reakčních podmínek a kontinuální provoz. Článek dále uvádí, shrnuje a hodnotí i další jejich vlastnosti přinášející technologické či ekonomické výhody z hlediska produkce čistých enantiomerů. Publikace zároveň shrnuje nejvýznamnější parametry a provozní charakteristiky membránových separačních technik vhodných pro izolaci čistých optických izomerů a navrhuje a analyzuje možnosti jejich integrace s produkčními mikro-reaktory do jedné mikro-fluidní platformy, uvádí ale i výčet problémů, které ještě musí být vyřešeny, než tato nadějná reakčně-separační technika bude moci být převedena do produkčního měřítka.
