Reporting period:01.03.2023. - 31.05.2023 01.06.2023 The kinetics of leaching of noble metals and non-ferrous metals in a hydrochloric acid electrolyte solution (CHCl=6M) at an alternating current density i=0.8 A/cm2 from a raw material fraction with d <90 μm and a non-conductive part content of ⁓60% obtained in a disintegrator during the double grinding process was studied. Preparation of the report "Effect of the degree of dispersion of raw materials and the volume ratio of the electrolyte on the extraction process". The influence of the PCB powder insertion method (in the form of a dispersed phase and in contact with graphite electrodes) on the efficiency of metal leaching from the raw material mass with a particle size of 355-710 µm and a non-conductive fraction content of ⁓ 15 wt% in an electrolyte solution (CHCl=6 M) was investigated.

of these functional nanostructures will be examined from the fundamental point of view; however, adapted for practical applications including needs for specific high-tech products required by Latvian industry. As an example, proposed structures might be employed as solid-state laser amplifiers, as well as for imaging agents, cancer detection and drug delivery. The implementation of this project will be significant not only for scientific research, but also for major society due to diverse potential in physical, biomedical and pharmaceutical applications, and various technical solutions. Project progress (05.07.2020.-04.10.2020.) During this postdoc project period popular scientific article –‘’Optical nanothermometry as technique for pinpoint temperature sensing’’ have been made for publishing, with main focus on LIR technique. This area of optics provides pinpoint temperature detection in submicron scale, particularly important for bio-applications. The one big societal benefit of the non-contact
