Water-Soluble Copper Ink for the Inkjet Fabrication of Flexible Electronic Components

The aim of this work is preparation and investigation of copper conductive paths by printing with a different type of functional ink. The solutions based on copper-containing complex compounds were used as inks instead of dispersions of metal nanoparticles. Thermal characteristics of synthesized precursors were studied by thermogravimetry in an argon atmosphere. Based on the comparison of decomposition temperature, the dimethylamine complex of copper formate was found to be more suitable precursor for the formation of copper layers. Structure and performance of this compound was studied in detail by X-ray diffraction, test of wettability, printing on flexible substrate, and electrical measurements.     

Serum concentrations of trace elements and microcirculation during laser therapy for pneumonia

The impact of laser therapy in the multimodality treatment for pneumonia on the serum levels of trace elements and microcirculation was studied. A total of 105 patients with pneumonia were examined. The patients were divided into 2 groups: 1) 68 patients received laser therapy and 2) 37 patients took drug therapy alone. There was a more substantial reduction in the permeability of cellular membranes, a significant increase in the serum levels of iron and chromium, better circulation at the expense of a vascular component. The above changes highly correlated with laboratory data and external respiratory function parameters.

Endemic and biogeochemical characteristics of the territory of Chuvash Republic

The study of endemic and biogeochemical features of the territory of Chuvash Republic showed that dietary patterns of the local population reflect specific environmental factors including selenium, manganese, and iron deficiency. Calcium deficit is mainly due to poorly balanced nutrition.
