polymer-clay nanocomposite coatings have attracted much attention because of impressive enhancements of coating properties. in this research, both commercially available and isophoronediamine-modified montmorillonite clays were used to obtain epoxy-clay nanocomposite coatings. these nanocomposite materials with different clay loadings in the form of coatings were applied to cold-rolled steel (c...

Using scanning and transmission electron microscopy, the analysis of structure, phase elemental composition contact zone system coating (high-entropy FeCrCoNiMn alloy)-substrate (5083 alloy) after electron-beam processing was performed. The formation a multiphase, multielement submicro- nanocrystalline structure has been established. high-speed cellular crystallization in layers adjacent to sub...

Lithium iron borate (LiFeBO3) is a promising cathode material due to its high theoretical specific capacity, inexpensive components and small volume change during operation. Yet, challenges related to severe air- and moisture-induced degradation have prompted the utilization of a protective coating on the electrode which also improves the electronic conductivity. However, not much is known abou...

This paper seeks to establish a correlation between surface topographical defects and Water Vapour Transmission Rate (WVTR) measured under laboratory conditions for aluminium-oxide (Al2O3) barrier film employed in flexible photovoltaic (PV) modules. Defects in the barrier layers of PV modules causing high WVTR are not well characterised and understood. A WVTR of ~10 g/m/day is sufficient for th...

Polymer bulk hetero-junction solar cells of poly(3-hexylthiophene) (P3HT) donor and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) acceptor are fabricated by blade coating in toluene solution. Desired donor–acceptor self-organization is achieved without the slow drying process and high boiling point solvent. Power conversion efficiency is 3.8%, much higher than the 2.6% obtained by spin coat...

Anxiety is feeling of danger in a person who is threatening with something. Nowadays, anxiety is increased in different populations and, thus it is became an important problem in many countries. Melissa officinalis (Melissa) and Valeriana officinalis (Valerian) are two medicinal plants. These two plants are traditionally used as sedative herbal drugs and new studies on their pharmacological act...

Overhead transmission line is the main method of power transmission. Conductors, insulators, and towers are primary electrical equipment overhead lines. Due to lines work in natural environment, problems such as icing, corona discharge, contamination deposition, corrosion will arise. As a result, some accidents may occur, which cause enormous economic losses. The above can be solved by coating ...
