Currently, many inorganic materials are investigated for modifying asphalts, but biomass ash is rarely applied to the modification of asphalt. In this present work, rice-husk-ash, as a representative of the biomass ashes, was added as a modifier to evaluate the related performance. The result showed that the basic per…
Abstract A new class of C3‐symmetrical fullerene building blocks with a well‐defined spatial arrangement of addends has been developed. They comprise compounds with a e,e,e‐trisaddition pattern and a mixed octahedral hexakisaddition pattern. Fullerenophosphates with a e,e,e‐addition pattern were used for the spatial p…
Phase transitions in hexagonal lattices with three and four rows of dipoles arising as a result of the reorientation of different sets of dipoles by the external field have been studied. The conditions of the implementation of two types of symmetric phase transitions and the asymmetric transitions, when the configurat…
In this article, the Multiple Scales Method is used to analyze the chaotic behavior and different types of fixed points in ferroresonance of voltage transformers considering core loss. This phenomenon has nonlinear chaotic dynamics and includes subharmonic, quasi‐periodic, and also chaotic oscillations. In this articl…
In this paper, we expounded the superconductive nature for fullerenes, which are being explored for the molecular electronics applications. The fullerene we picked for our research work is the C24 which was then doped with popular dopants- Boron, Nitrogen and Phosphorus and the self-consistent calculations were perfor…
The article specifically deals with the compression molding technology and new possibilities to bring the whole technology to higher level in innovation. Identifies the methods and describe the best possible method to increase the productivity. Article introduces the compression molding technology, and how the preheat…
Electrogenicity of Shewanella oneidensis MR-1 mutants FRS1 and FRB1 with reducing activity 30–40% higher than in the original strain was studied in various microbial fuel cells (MFC) developed in the course of the work. The voltage and current density developed by the mutants were 1.7 times higher than in the case of…
Abstract In many occupational settings, clothing must be worn to protect individuals from hazards in their work environment. However, personal protective clothing (PPC) restricts heat exchange with the environment due to high thermal resistance and low water vapor permeability. As a consequence, individuals who wear P…
We investigate the effects of ultraviolet (UV) irradiation treatment with varying irradiation intensities for different treatment times of poly(3, 4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) film on the performance and stability of polymer solar cells (PSCs) based on regioregular poly(3-hexylthiophene…
When reinforced concrete structures exposed to marine environments have both water-saturated and aerated parts, for instance, submerged tunnels or parking areas, a macrocell can develop. The electrochemical potential and the corrosion rate of reinforcing steel in the saturated part may increase because of this phenome…
The peculiarities of polyester-resin synthesis processes and their advantages, disadvantages, and basic properties are considered. Technological processes of production of goods made of polymeric composite materials based on polyester resin by pressing technique are studied.
This paper discusses recent modifications to the Serpent Monte Carlo code methodology and related to the calculation of few-group diffusion coefficients and reflector discontinuity factors The new methods were assessed in the following manner. First, few-group homogenized cross sections calculated by Serpent for a ref…
Here, we report on the study of cationic amidoammonium calix[4]resorcinarenes 1–5 of various lipophilicity capable of binding acid–base indicator methyl orange (MO). We identified the contributions of macrocycle aggregation and conformational mobility in the binding of MO. The effective pKa values of bound MO systemat…
Fatigue characterization is an important concern for structural materials. The fatigue behaviour of aluminium (Al) composite reinforced with carbon nanotubes (CNT) is of interest besides its improved strength. In this study, tension-tension fatigue tests were conducted on monolithic Al and Al reinforced with 0.5, 1 an…
In the present study, the investigation of weldability of new ultra-high strength - Weldox 1300 steel has been presented. The thermal simulated samples were used to investigate the effect of welding cooling time t8/5on the microstructure and mechanical properties of the heat affected zone (HAZ). In the frame of these…
Abstract. Vehicles burning fossil fuel emit a number of substances that change the composition and chemistry of the atmosphere, and contribute to global air and water pollution and climate change. For example, nitrogen oxides and volatile organic compounds (VOCs) emitted as byproducts of fossil fuel combustion are key…
Summary The formation of poly(etheylene glycol) (PEG) model network hydrogels via an A2 + B3 inverse‐electron‐demand tetrazine‐olefin Diels‐Alder cycloaddition is reported. This method provides an efficient, additive‐free, colorimetric gelation reaction that will complement other “click chemistry” approaches to model…
Resonant and leaky-wave THz reconfigurable antennas based on the propagation of transverse magnetic surface plasmons on graphene sheets are proposed. Reconfiguration is achieved via electric field gating, which allows the dynamical control of graphene complex conductivity. The first presented antenna is a miniaturized…
CNTs-Al matrix composites are considered to be promising heat dissipating materials because thermal conductivity can potentially be improved whilst their density is reduced. Although casting has many advantages in the fabrication of large, complex components, this process cannot be easily employed when manufacturing C…
Ag 2 O/Ag 3 PO 4 heterostructures photocatalysis was prepared for the first time. Photocatalytic tests displayed that the Ag 2 O/Ag 3 PO 4 heterostructures possessed a much higher degradation rate of methyl orange and phenol than pure Ag 3 PO 4 under visible light. The enhanced photocatalytic activity could be attribu…
