Despite the availability of large number of empirical and semi-empirical models, the problem of penetration depth prediction for concrete targets has remained inconclusive partly due to the complexity of the phenomenon involved and partly because of the limitations of the statistical regression employed. Conventional…
Engineered yarns are used to provide better clothing comfort for summer garments because of their high levels of moisture and water vapor management. The aim of this study was to investigate the characteristics of knitted structures that were produced using different types of polyester yarns in order to achieve better…

A phosphor-free near-white-light-emitting diode (LED) is demonstrated by using a conducting polymer, poly(3, 4-ethylenedioxythiophene):poly(styrenesulphonic acid) (PEDOT:PSS) and a CdSe quantum dot (QD) composite layer that was fabricated by using a simple and inexpensive solution-based process. The PEDOT:PSS is depos…
The properties of carbon nanomaterials, produced with the help of the method for the high-frequency electrodischarge processing of hydrocarbon gases, based on the creation of non-equilibrium plasma under variation of frequency and treated gas, have been studied. It is shown that the synthesis of onion-like structures…
To extend the working life of molds in continuous-casting machines, diffusional aluminum layers (thickness around 1.5 mm) are sprayed on their narrow walls, made of M1 copper and MN2.5KoKrKh copper alloy, with subsequent diffusional annealing at t = 800°C for 10 h in an oxidative atmosphere. At the surface of M1 coppe…
Abstract In the paper, the passive surface layers of AISI 304L after standard (EP50) and very-high-current density electropolishing (EP1000) in a mixture of orthophosphoric and sulfuric acids in a 1:4 ratio, are presented. The main finding of the presented studies is enrichment of the steel surface film in chromium: t…
Despite the significant progress in molecular imaging technologies that has been made in recent years, the specific detection of neural cells still remains challenging. Here, we suggest the use of gold nanoclusters (AuNCs) modified with a brain-targeting peptide as a potential imaging candidate for detecting neural ce…
TiO2 films were prepared by sol–gel methods with butyltitanate as main raw materials. Structural and electrochromic properties were investigated by XRD, SEM, electrochemical workstation and Ultraviolet visible spectroscopy. The results indicate that the TiO2 films have better electrochromic properties when the films a…
In nature, cells respond to complex mechanical and biological stimuli whose understanding is required for tissue construction in regenerative medicine. However, the full replication of such bimodal effector networks is far to be reached. Engineering substrate roughness and architecture allows regulating cell adhesion,…
Biodistribution of nanoparticle-based intracellular delivery systems is mediated primarily by particle size and physicochemical properties. As such, overcoming the rapid removal of these by the reticuloendothelial system remains a significant challenge. To date, a number of copolymer nanoparticle systems based on 2-me…
Structural-dynamic analysis based on combined thermophysical and molecular mobility measurements via spin-probe ESR spectroscopy has been applied to films and fibrous matrixes based on poly(3-hydroxybutyrate). The dynamic behaviors of partially crystalline samples during deformation under conditions of electrospinning…
Biodegradable polymeric film composites consisting of chitosan ( Cht ) and poly(3-hydroxybutyrate) ( PHB ) have been produced and used to encapsulate colloidal magnetite nanoparticles ( MNPs ) and a drug (dipyridamole). The magnetic organization of the MNPs induced by the exposure of the films to external magnetic fie…
An experiment has been performed on the collapse of a thick steel cylindrical shell into a continuous cylinder under the action of a sliding detonation wave. The process of the collapse has been recorded via X-ray photography, and it has been found that the time of collapse in one section is equal to 30 μs. The averag…
The target audience for this Special Section comprises parties related to the food and feed sectors, e.g., field samplers, academic and industrial scientists, laboratory personnel, companies, organizations, regulatory bodies, and agencies who are responsible for sampling, as well as project leaders, project managers,…
Chain extension was an effective method for increasing the molecular weight, the melt strength and the foaming property of linear polymer. In this paper, pyromellitic dianhydride (PMDA) was used as chain extender to improve these properties of linear poly (ethylene terephthalate) (PET). The intrinsic viscosity, rheolo…
In this paper we demonstrate the validity of a mathematical chamber model to describe the absorption, distribution, and bioaccumulation of nonmetabolizable nanoparticles (NPs) using the example of silver NPs in the organism of laboratory rat. The model is constructed using experimental data on the bioaccumulation and…
In this study, irregular cubic phase NiO nanosheets (30.0-100.0 nm in width, 10.0-13.0 nm in thickness) with large specific surface area (120.5 m2g-1) have been synthesized for both Li-ion batteries and supercapacitors. The superior electrochemical performance including large reversible capacities, high specific capac…
Copper Oxide (CuO) nanoparticles were synthesized by the wet chemical method. The crystal structure and grain size of the particles were determined, using X-ray diffraction (XRD). The particle size and morphology were studied using the scanning electron microscope (SEM). The dielectric properties of CuO nanoparticles…
Polysaccharides are attracting the vigil eye of researchers in order to design the green synthesis of silver nanoparticles (Ag NPs) of diverse size, shape, and application. We report an environmentally friendly method to synthesize Ag NPs where no physical reaction conditions were employed. Hydroxypropylcellulose (HPC…
