High‐Q Cavity Coupled to a High Permittivity Dielectric Resonator for Sensing Applications

open access: yesAnnalen der Physik, EarlyView.
Electromagnetic simulations and microwave measurements at temperatures as low as 160 mK are used to investigate a hybrid system of a SrTiO3${\rm SrTiO}_3$ resonator and a high‐Q elliptical cavity. By using the STO puck as an active element sensitive to external quantities, and using high‐precision measurements on the high‐Q cavity, the potential for ...

Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

open access: yesChemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...

Design of a Solar Energy Storage Emergency Rescue Backpack Integrated With Global Positioning System, Light Emitting Diode, and a Heating Module

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Mountain climbing often involves sudden weather changes, group separation, and mobile device battery depletion, which can lead to life‐threatening emergencies. Enhancing survival and extending rescue time in such situations are crucial, making power supply and emergency equipment essential considerations.
