Carbon Allotropes-Based Paints and Their Composite Coatings for Electromagnetic Shielding Applications.

The present manuscript reports on optimized formulations of alcohol-based conductive paints for electromagnetic interference shielding (EMI), which can ensure compatibility and reduce the visibility of electronic equipment, as a continuation of our previous work in this field, which examined water-based formulations for other applications. Graphite, carbon black, graphene, FeO, Fe ore, and PEDOT:PSS in various ratios and combinations were employed in an alcohol base for developing homogeneous paint-like fluid mixtures that could be easily applied to surfaces with a paintbrush, leading to homogeneous, uniform, opaque layers, drying fast in the air at room temperature; these layers had a reasonably good electrical conductivity and, subsequently, an efficient EMI-shielding performance. Uniform, homogeneous and conductive layers with a thickness of over 1 mm without exfoliations and cracking were prepared with the developed paints, offering an attenuation of up to 50 dB of incoming GHz electromagnetic radiation.

Novel Water-Based Paints for Composite Materials Used in Electromagnetic Shielding Applications.

The development of materials offering electromagnetic interference (EMI) shielding is of significant consideration, since this can help in expanding the lifetime of devices, electromagnetic compatibility, as well as the protection of biological systems. Conductive paints used widely today in electromagnetic interference (EMI) shielding applications are often based on organic solvents that can create safety issues due to the subsequent environment problems. This paper concerned the development of eco-friendly conductive water-based paints for use in EMI-shielding applications.

Possibilities of correction rheological blood svoytv at chipped and cut wounds of the breast .

The purpose: research objective: to study influence of electromagnetic oscillations of millimetric range on rheological properties of blood at patients with chipped and cut wounds of a breast for the purpose of their correction. Methods. For the solution of a research objective we have carried out studying of changes of rheological properties of blood at the 22nd patient with the getting chipped and cut wounds of a breast without internal injury during the next postoperative period.

[Changes in the immune status of patients operated for splenic lesions in the late postoperative period and their relation to the development of complications].

This analysis of changes in the immune status of patients operated for splenic lesions is based on the observations of 126 subjects. Fifty of them underwent autolientransplantation and 26 conservative surgery. The main parameters of humoral and cellular immunity were measured along with changes in the microflora.
