Ho3+ codoping of Lu3Al5O12 activated with Pr3+ (LuAG:Pr) induces an acceleration of Pr3+ decay kinetics. This is caused by nonradiative energy transfer from Pr3+ to Ho3+ driven by a multipolar electromagnetic interaction. Luminescence and scintillati

Fabrics with metal threads were discovered in mediaeval well during excavations in the Mecova 2 Street in Brno. These are thin braids woven of metal threads using a small loom and sewed together into a broader strip. The textile materials are in a re

This investigation focuses in detail on the analysis of discoveries in South Moravia – important sites from the Roman period in Pasohlavky and Musov. Using X-ray fluorescence analysis and micro-analysis we help identify the techniques of enamel pai

A long-term application of various mulch materials may lead to changes in certain soil properties, which mostly remain unreviewed. Therefore, our study focused on the mulch effect on a larger group of Haplic Fluvisol properties. The experiment was pe
