ABSTRACT

Vďaka platforme IMPULZ CORONA STU, ktorá vznikla s cieľom sieťovania výskumníkov na STU počas pandémie, sa podarilo v máji 2020 prepojiť dizajnérsku iniciatívu COVID COLAB Michaly Lipkovej a Vlasty Kubušovej s technológiami výskumnej skupiny Slovak Diamond Group Ustavu elektroniky a fotoniky FEI STU pod vedením Mariána Vojsa. Základom technológie je špeciálne povrchovo upravená penová keramika s aktívnou fotokatalytickou vrstvou, ktorá pomocou ožiarenia UV svetlom degraduje škodlivé látky z ovzdušia (cigaretový dym, rozpúšťadlá, NOx a pod.). Softvérová časť modulu č. 2 vznikla ako súčasť bakalárskej práce Adama Ru- žičku pod vedením Richarda Balogha z Ustavu automobilovej mechatroniky FEI STU.

ABSTRACT

First he examined the interactions between the lingering effects of the COVID-19 pandemic and current economic and social transformations. In light of the session in his honour, Dr George Harlow (American Museum of Natural History, New York, USA) chronicled the history of his career, in which he built collections, organised exhibitions and performed geological fieldwork around the world while researching jade, ruby, etc. Pamir rubies formed at unusually low pressures (minimum of 1–1.2 kbar) and a temperature of approximately 760°C. Wim Vertriest (Gemological Institute of America [GIA], Bangkok, Thailand) and co-authors reviewed the identification of low-temperature heat treatment of gem corundum (i.e. up to about 1200°C, which starts causing damage to rutile ‘silk’ inclusions). In another presentation, Dr Dutrow and co-authors investigated the origin determination of Cu-bearing tourmaline using statistical analyses of LIBS and electron microprobe data.
