Background Opicapone is a high binding affinity and long‐acting third generation nitrocatechol COMT inhibitor under development for use as adjunctive therapy in levodopa‐treated Parkinson's disease (PD) patients. Objectives The aim of this study was to evaluate the effects of opicapone, as adjunctive therapy to levodo…
Gln3 is the major transcription activator mediating nitrogen‐responsive gene expression in Saccharomyces cerevisiae . When cells are cultured in nitrogen‐replete environments (excess glutamine, asparagine or ammonia media), Gln3 is sequestered in the cytoplasm thereby minimizing nitrogen catabolite repression‐ (NCR‐)…
This study aimed to explore the properties of the complex hydrides which seem to be the promising candidates for hydrogen storage materials. The geometrical structure, vibrational spectra and thermodynamic characteristics of the gaseous complex hydrides, MXH3 and M2XH4 (M = Li, Na; X = Be, Mg) and the subunits LiH, Na…
It was hypothesised that agronomically suitable controlled release fertilizers (CRFs) can be prepared using synthetic and/or natural biopolymers and polymer-clay nanocomposite excipients. Literature has focused almost exclusively on the urea-CRFs basing on intercalations and/or encapsulations leaving behind a question…
PCDA (Pentacosadiynoic Acid) monomers were successfully embedded in PCL (Poly ?-Caprolactone) polymer matrix by electrospinning process for the first time. The resultant EFM (Electrospun Fibers Mat) was photo-polymerized under 254 nm UV light that enables colorimetric detection of fake gasoline. Results revealed that…
We consider a boundary regime problem for 1D wave propagation in a metamaterial medium with simultaneously negative dielectric permittivity and magnetic permeability. We apply a projecting operator method to the Maxwell system in the time domain that allows the space of the linear propagation problem to be split into…
The article set the task of improving the ultrasonic inspection of wheelset axles of railway rolling stock by increasing the reliability of the inspection results. Taken into account the specificity of the wheelset axles production defects, which may occur in it due to failures in technological processes of production…
Abstract This case study reviews the considerations in applying plasma spray thermal barrier coatings on augmenters used in military aircraft turbine engines to extend their service life.
Abstract The Materials Genome Initiative aims to enable discovery, manufacture, and deployment of advanced materials twice as fast as using traditional development methodologies, at a fraction of the cost. This article explores how semantic technologies address three of the key challenges outlined in the MGI Strategic…
Abstract This new article series explores the indispensable role of characterization in the development of cold spray coatings and illustrates some of the common processes used during coatings development. This article provides a list of techniques to be covered in subsequent articles.
Abstract This article describes work being done at the University of Limoges to develop thermal spray coatings for use in new nuclear power plant designs.

The details of making technology of porous permeable material with use of wire are allowed to carry out the analytical research of structure and structural characteristics of wire winding body. Its permit for prognostication the final proper-ties of material, that is produced by the following deformation treatment (di…
The possibility of increasing the hardness (strength) nonburning-on coatings based on distensilimonita and lingosulfanata as binding by the addition of sodium aluminate and polyethylene glycol (PEG-200) was usearched. It was found that addition of these substances enhances strength for the first one temperature ranges…
Imitation modeling of direct hot extrusion of bushes made from high-strength cast iron is performed using finite-element method. The evolution of stress and strain fields during processing and the probability of crack formation are evaluated. The specific feature of the work is that during hot forming a special techni…
Poly(MA-\\textit{alt}-MVE)-$g$-PLA/ODA-MMT nanocomposite was prepared by self-catalytic interlamellar graft copolymerization of L-lactic acid (LA) onto poly(maleic anhydride-\\textit{alt}-methyl vinyl ether) copolymer in the presence of octadecyl amine-montmorillonite (ODA-MMT) organoclay. FTIR, $^{1}$H ($^{13}$C) NMR…
In this research, electrochemical exfoliation process of the graphite as electrode immersed in a sulfuric acid, nitric acid and water (H2SO4/HNO3/H2O) was used to produce high-quality graphene. The structural and chemical properties, of the prepared graphene were studied. XRD shows that the structure of grapheneis pol…
Recently, has been studied the electro-optical properties of the polymer dispersed liquid crystal (PDLC) systems because it has unique properties use in smart windows technology. The selection of material is important for performance and application of polymer dispersed liquid crystal devices. The choosing of the mate…
Traditional chemotherapy in the form of cytotoxic drugs is one of the standards in cancer treatment, but it is hindered by various barriers to drug delivery throughout the cancer microenvironment. Recently, nanoparticles have been of great interest as drug delivery vectors because they can be tailored for specific fun…
Zinc Oxide (ZnO) is an important semiconductor material due to its broad applications, such as in the fields of electronics, optoelectronics, photocatalysts, and solar cells. The main purpose of this work was to investigate the effect of pressure in post-hydrothermal treatment on crystallinity enhancement, crystallite…
