This study focuses on improvement of mechanical and physical properties of polypropylene (PP) composite using filler, modifier and jute fiber as reinforcement. Rice husk ash (RHA), low-density polyethylene (LDPE) and jute fiber were used as filler, modifier, and reinforcement in the PP matrix, respectively. A series o…
The present work compares the tensile properties of polyester and epoxy matrix composites reinforced with hemp fibers. Polyester and epoxy reinforced with different volume fractions of hemp fibers up to 30% were prepared according to ASTM D-638-14 and tensile tested. The epoxy matrix composites reinforced with 30% of…
Molecular dynamics simulations on the indentation process of freestanding and Pt(111)-supported black phosphorus (BP) monolayer were conducted to study the fracture mechanism of the membrane. For the freestanding BP monolayer, crack grows firstly along armchair direction and then zigzag direction during the indentatio…
In the published article, incorrect data for the AM 1.5 reference solar spectrum were used, leading to an incorrect value being quoted for the EQE and overvalued J sc and PCE.
A novel organic single crystal of p -toluidinium salicylate (PTSA) was grown by slow evaporation solution growth technique. The structure of grown crystal was determined from the single crystal X-ray diffraction analysis. The functional groups existing in PTSA crystal were accomplished by using Fourier transform infra…
The pollution flashover accidents of insulator strings do harm to the safe operation of transmission lines. The paper aims to investigate the flashover characteristics of a 2-unit glass suspension string under 0.5/5μs short-tail impulses. Firstly, in order to represent the pre-heating effect of operation voltage, a co…
The mass distribution along a flow of microparticles is measured by methods of synchrotron radiation generated by the VEPP-3 collider. The use of the soft spectrum of radiation allows microparticle flows to be measured with a record-beating (minimum) specific density (1 mg/cm 3 ). Simultaneous recording of micropartic…
Lightning has been known as one of major factors that cause power line failure in Malaysia. Presence of contaminants on polymer insulator surface will reduce voltage withstand capabilities in the event of lightning and could lead to insulator failure or worst power line disruptions. This paper presents a study on effe…
Objective(s): Application of eco-friendly materials like poly lactic acid (PLA) is increasing, to reduce environmental pollutions. In this research, the effect of silicon dioxide 1%, 3% and 5% nanoparticles on morphological, mechanical and chemicals interaction (FTIR) of PLA film was studied. Materials and Methods: Sc…
Is vanadium dioxide (VO2) an all-around champion? In article number 1802025, Ming Li, Yi Long, and co-workers from Nanyang Technological University Singapore summarized the diverse applications of VO2 by different input and output stimuli-responses. VO2 is a textbook example of a phase-transition material that can swi…
The study is relevant due to necessity of improvement of thermal and physical features of composite materials for ensuring the size stability of composite structures. Therefore, this Article is aimed at developing an automatized system for determining the thermal conductivity of thermosetting polymers by modified nano…
To examine the possibility of disposal of irradiated graphite in ground near-surface repositories, the concentration and spatial distribution of radionuclides in the volume of irradiated graphite sleeves of industrial uranium–graphite reactors was studied, and the efficiency of decontamination using liquid reagent tre…
The correlation of the chemical composition, the structure, and the microwave characteristic of solid solutions of the BaFe 12 – x D x O 19 (0.1 ≤ x ≤ 1.2) barium hexaferrite substituted with diamagnetic Al 3+ and In 3+ ions has been studied. The precise data on the crystal structure have been obtained by powder neutr…
The evolution of a structural–temporal integral criterion of yielding is reported for the description of the dynamic deformation of metals. The values of characteristic relaxation times, considered as the constants of the material, are shown to be suitable for the description of dynamic effects upon the nanomaterial d…
Inspired by experimental work on colloidal cuboid-polymer dispersions (Rossi et al., Soft Matter, 7, 4139 (2011)) we have theoretically studied the phase behaviour of such mixtures. To that end, free volume theory (FVT) was applied to predict the phase behaviour of mixtures of superballs and non-adsorbing polymer chai…
This article studies the free and forced vibrations of the carbon nanotubes CNTs embedded in an elastic medium including thermal and dynamic load effects based on nonlocal Euler- Bernoulli beam. A Winkler type elastic foundation is employed to model the interaction of carbon nanotube and the surrounding elastic medium…
Bird pecking is one of the causes for deterioration of composite insulators. It concerns the removal of parts of the polymeric housing due to the attack by large birds. Such damages on the insulator housing rise questions concerning the efficiency and reliability of the bird-pecked insulators. This study evaluates the…
Papers dealing with chemical modification of the surface of noble metal nanoparticles and their use in analytical and bioanalytical chemistry, pharmacology, etc., are analyzed. Grafting of a layer of preset chemical composition on the nanoparticle surface allows preparation of functional materials combining the proper…
In this work, the composition of formed products and the dynamics of decomposition related to thermal explosion and at temperatures that are stepwise increased have been experimentally studied for graphite oxide. The gaseous products formed in the explosive and stepwise thermal reduction of graphite oxide within a ran…
