Thermoradiationally Modified Polytetrafluoroethylene as a Basis for Membrane Fabrication: Resistance to Hydrogen Penetration, the Effect of Ion Treatment on the Chemical Structure and Surface Morphology, Evaluation of the Track Radius.

A study of the properties of thermoradiationally modified polytetrafluoroethylene and its importance for use as the basis of polymer membranes is presented. The hydrogen permeability of a TRM-PTFE film was studied in comparison with an original PTFE film, and showed a three-fold decrease in hydrogen permeability. Further, TRM-PTFE films were irradiated with accelerated Xe ions with an energy of 1 MeV with fluences from 1 × 10 to 1 × 10.

Structure of Polytetrafluoroethylene Modified by the Combined Action of γ-Radiation and High Temperatures.

By means of X-ray computed microtomography (XCMT), the existence of a developed porous structure with an average pore diameter of ~3.5 μm and pore content of ~1.1 vol.

The Emergence of Sequential Buckling in Reconfigurable Hexagonal Networks Embedded into Soft Matrix.

The extreme and unconventional properties of mechanical metamaterials originate in their sophisticated internal architectures. Traditionally, the architecture of mechanical metamaterials is decided on in the design stage and cannot be altered after fabrication. However, the phenomenon of elastic instability, usually accompanied by a reconfiguration in periodic lattices, can be harnessed to alter their mechanical properties.

[APPLICATION OF VACUUM-THERAPY IN COMPLEX OF TREATMENT OF THE LOWER EXTREMITIES CHRONIC WOUNDS].

Experience of treatment of chronic wounds in 11 patients in 2014 – 2016 yrs was analyzed. The impact of negative pressure, using domestically manufactured apparatus «АGАТ- Dnepr», in complex of treatment as a local therapy, was applied. Vacuum-therapy was conducted preoperatively and postoperatively together with autodermoplasty.

Blood transfusion trigger in burns: a four-year retrospective analysis of blood transfusions in eleven burn centers in Ukraine.

One focus of improvement of burn care in Ukraine was the management of blood loss and blood transfusions in burn patients. The aim of this project was to analyze blood transfusion triggers in burn patients and outcomes at eleven major burn centers in Ukraine. This multicenter retrospective study reviewed four years of data on blood-transfused burn patients admitted to eleven major burn centers in Ukraine.
