The first vapor-phase deposition of poly(vinyl cinnamate) (PVCin) is reported. Initiated chemical vapor deposition (iCVD) is used to synthesize PVCin thin films with an average thickness of 100 nm. Free radical polymerization and cyclization reactions compete during the deposition process, with approximately 45% of th…
The present review focuses on the properties and developing applications of carboxylated styrene butadiene rubber (XSBR) as a modified grade of styrene butadiene rubber (SBR). Carboxylated polymers, and particularly carboxylated rubbers, are regarded as a new class of polymers with superior physical and mechanical pro…
A highly stable and uniform dispersion of multiwall carbon nanotubes in aqueous solution was achieved to prepare multiwall carbon nanotubes/gelatin–polyvinyl alcohol nanocomposites with varying multiwall carbon nanotubes content using solution casting. Optical microscopic images confirmed the homogenous dispersion and…
In this work, we report the formation and growth mechanisms of gold nanoparticles (AuNPs) in eco-friendly deep eutectic solvents (DES; choline chloride and urea). AuNPs are synthesized on the DES surface via a low-energy sputter deposition method. Detailed small angle X-ray scattering (SAXS), UV-Vis, and cryogenic tra…
The stability of a single-walled carbon nanotube placed on top of a catalytic nickel nanoparticle is investigated by means of molecular dynamics simulations. As a case study, we consider the $(12,0)$ nanotube consisting of 720 carbon atoms and the icosahedral Ni$_{309}$ cluster. An explicit set of constant-temperature…
Semiconductor-sensitized solar cells (SSCs) are emerging as promising devices for achieving efficient and low-cost solar-energy conversion. The recent progress in the development of ZnO-nanostructure-based SSCs is reviewed here, and the key issues for their efficiency improvement, such as enhancing light harvesting an…
A series of semiconducting polymer dots (Pdots) composed of phosphorescent Ir(III) complexes and polyfluorene units in the main polymer chains are designed, synthesized, and applied in ratiometric oxygen sensing and photodynamic cancer therapy. The ultrasmall Pdots with particle size less than 10 nm are fabricated in…
Radiosensitizers can increase local treatment efficacy under a relatively low and safe radiation dose, thereby facilitating tumor eradication and minimizing side effects. Here, a new class of radiosensitizers is reported, which contain several gold (Au) atoms embedded inside a peptide shell (e.g., Au10-12 (SG)10-12 )…
Large-area freestanding graphene papers (GPs) are fabricated by electrospray deposition integrated with a continuous roll-to-roll process. Upon mechanical compaction and thermal annealing, GPs can achieve a thermal conductivity of as high as 1238.3-1434 W m(-1) K(-1) . The super-thermally conductive GPs display an out…
Two series of samples are prepared to investigate the viscoelastic properties of Gel Polymer Electrolytes. Samples were prepared by gelation technique with different oxygen to sodium ratio. For the present work, we take Poly(vinylidenfluoride) as polymer, sodium perchlorate as salt and of ethylene carbonate and propyl…
The current work deals with numerical and experimental analysis of thermal conductivity of epoxy matrix composites filled with coconut coir dust. The numerical analysis proceeds with designing of 3-dimensional spheres-in-cube models with filler concentration ranging from 0-20% volume (approximately) and its thermal an…
The authors propose a method for testing plastics endurance under plane transverse bending with a given cyclic deformation. The paper describes the relations for the calculation of the amount of deflection, rotation angles of the end parts of a sample and the technological gap d between the pins in movable supports an…
The article discusses the possibility of local and deep wastewater treatment of an automobile plant when painting automobile bodies. Experimental studies were carried out using coagulants extracted from waste (M); sorption methods (filtration through hydroanthracite and portlandite).
The article considers the method and algorithm of the computer analysis of viscoelastic deformation of a beam in a non-stationary temperature field. The data of program realization of the offered method of calculation are presented. The example of calculation of process of unsteady creep of a beam is adduced at thermo…
