Using the laser ablation method, AgI stoichiometric compound films, (GeSe2)30(Sb2Se3)30(AgI)40 glass films, and films comprised of alternating layers of AgI and the glass were obtained. Individual layer thickness amounts to 10 nm, and the total number of layers is about 100. Film conductivity measurements were carried out during several cycles of heating up to 200 °C and cooling to room temperature. It was established that after three cycles of thermal processing specific lateral conductivity of the film is equal to 0.3 S cm−1 and conductivity activation energy is equal to 0.07 eV at room temperature.

This paper presents data on fabrication of “nickel-graphene-graphite” bulk composites using powder metallurgy methods combined with the high energy ball milling. The composites were then processed by high pressure torsion (HPT) at temperatures of 23 and 200 °C. This treatment gives rise to the formation of new “nanostructured nickel-graphene” composites. The phase composition of the new composite specimens was examined by X-ray diffraction. Raman spectroscopy proved graphite-to-graphene conversion under mechanical treatments. The microstructure of the new composite specimens was investigated by scanning electron and transmission electron microscopy methods. Composite specimens after HPT at temperature of 200 °C demonstrate the optimal combination of strength (σ02= 923 MPa; σb= 992 MPa) and ductility (δ = 99%). Composite specimens with 2 wt.% graphene content after HPT at room temperature exhibits superior microhardness Hv = 6.45 GPa.

1,5-bis(R)-3,7-bis[2-(pyridine-2′-yl)ethyl)-1,5-diaza-3,7-diphosphacyclooctanes 1 and 2 and their copper(I) complexes 3 and 4 were developed. The butterfly-shaped copper-iodide core and unusual P,N-chelate and P,P-bridged coordination mode of the heterocyclic ligand in the dinuclear complexes 3 and 4 were revealed. Complexes 3 and 4 display emission in green range of spectra, with lifetimes in a microsecond domain and quantum yields of luminescence in solid-state up to 38 %. Thermochromic effects found for the phosphorescence of 4 in solutions are ascribed to rigidochromism.

The real controlled photothermal therapies demand designing multifunction systems capable of simultaneous heating and local thermal sensing. In this work, we report on neodymium doped yttrium vanadate nanoparticles acting as nanoheaters and nanothermometers at the same time under 808 nm single beam excitation. Heating is produced due to the nonradiative processes, whereas thermal sensing is obtained by luminescence intensity ratio between Stark sublevels lying in the second biological window. The influence of Nd3+ content on both heating and sensing abilities was studied. The potential application of YVO4:Nd3+ nanoparticles for deep tissue fluorescence bioimaging and controlled photothermal therapies is demonstrated.
