Article
The vast majority of light-emitting diode and liquid-crystal displays, solar panels, and windows in residential and industrial buildings use glass panels owing to their high mechanical stability, chemical resistance, and optical properties. Glass surfaces reflect about 4-5% of incident light if no antireflective coating is applied. In addition to e...

We studied NE-4C neural cells differentiation on 2D polycaprolactone (PCL) nanofibrous scaffolds with systematically varied mechanical characteristics of nanofibers while retaining an unchanged fiber alignment, diameter, and chemical composition. Our experiments demonstrated that the nanofibers with enhanced mechanical properties are beneficial for...
Article
Robust, simple, and scalable touch- and brush-spinning methods for drawing of nanofibers, core-shell nanofibers, and their aligned 2D and 3D meshes using polymer solutions and melts are discussed.

Magnetic field assisted assembly is used to fabricate aligned single nanowire mesh-like nanostructured films. Inhomogeneous magnetic field is applied to translocate high aspect ratio silver nanowires from suspensions to the surface of solid supports. The tangential component of the magnetic field vector is rotated in two consecutive steps to arrang...
Article
Novel composite membranes based on polyolefins for intermediate and high temperature (120–160 °C) phosphoric acid fuel cells with polymer matrices have been synthesized and their properties have been studied, including testing in operating fuel cells. In contrast to polybenzimidazoles uniformly swelling with H3PO4, which are typically used as membr...

FIELD: process engineering. SUBSTANCE: invention relates to proton-conducting membranes to be used in electrochemical current sources, for example, in medium-temperature solid-polymer fuel cells. Proposed method consists in treatment of porous polymer film from polyethylene or propylene containing 20-45 wt % of silicon dioxide in its pores by ortho...

FIELD: chemistry. SUBSTANCE: membrane of a membrane electrode unit of a fuel cell additionally contains an additive in form of oligomeric perfluorosulphonic acid. This additive dissolves in dopant acid and is introduced into the membrane during doping thereof. The membrane can be made from polybenzimidazole. EFFECT: improved discharge characteristi...
