Mechanical displacement in commonly used piezoelectric materials is typically restricted to linear or biaxial in nature and to a few percent of the material dimensions. Here, we show that free-standing BaTiO$_3$ membranes exhibit non-conventional electromechanical coupling. Under an external electric field, these supe…
Within the RCo$_2$ family of compounds, a structural distortion linked with the onset of magnetic ordering around the critical temperature can be observed. One of the less explored RCo$_2$ compounds is TmCo$_2$ probably due to its low Curie temperature. Exceptionally this compound, given its position at the end of the…
Nanotechnology empowered localized cancer chemotherapy has indicated a promising performance for targeting and controlled release of anticancer agents over a period of time to eliminate local-regional recurrence of cancers and also to improve the tissue regeneration during/after treatment. Electrospun nanofiber-based…
Chitin is a kind of natural macromolecule material which was first discovered in mushrooms and was widely found in the shells of crustaceans and arthropods, the cell walls of fungi (yeast and mold) and algae, and the mollusks. The original chitin in nature usually has an antiparallel molecular chain alignment forming…
Recently, green-prepared oxidized graphenes have attracted huge interest in water purification and wastewater treatment. Herein, reduced graphene oxide (rGO) was prepared by a scalable and eco-friendly method, and its potential use for the removal of methylene blue (MB) from water systems, was explored. The present wo…
Electrochemical energy storage devices (EESs) play a crucial role for the construction of sustainable energy storage system from the point of generation to the end user due to the intermittent nature of renewable sources. Additionally, to meet the demand for next-generation electronic applications, optimizing the ener…
The specific features of the crystallization kinetics of the ternary Al-Ni-Fe system due to the order of the introduction of the alloying elements are explained in terms of the cluster structure of the melts of binary metal systems Al-Ni and Al-Fe.
A series of experiments was conducted in order to investigate the influence of the elastic characteristics of the reinforced composite material on the strength of the detachable rope threaded joint. Since the finite element simulation model of the detachable rope threaded joint was confirmed by an experimental study,…
The paper presents a process of industrial fabrication of 227 mm calibre frames made of 15HGMVŻ grade lowcarbon steel. Influence of production technology parameters such as the state of material before forming and the degree of deformation during the forming on mechanical properties of frames was established. Optimal…
O objetivo deste estudo foi avaliar a distribuição do teor de umidade das tábuas de pinus em câmaras de secagem. Foram analisadas a carga de madeira de pinus de duas estufas com capacidade de 100 m³ com espessuras das tábuas de 27 e 42 mm. O teor de umidade final (TUF) das tábuas após a secagem foi avaliado em diferen…
Досліджено вплив міді як модифікуючої добавки на властивості in vitro біокераміки на основі біогенного гідроксіапатиту та натрійборосилікатного скла та встановлено, що введення міді у кількості 0,5–2,0 мас. % знижує рівень рН фізіологічного розчину, а також швидкість розчинення матеріалу у модельному середовищі, що да…
The present work involves the development of chitosan-pomegranate peel extract and silver nanoparticles (Cs-PPE-AgNPs) using electrochemical process followed by UV irradiation reduction. Formation of silver nanoparticles characterize by UV–vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffrac…
This work presents the main parameters of the current state of the world market of additive manufacturing equipment. For research, the most common type of additive technology was chosen, namely FDM (Fused Deposition Modeling) or 3D printing using thermoplastic polymer material. This technology is the most common and i…
A model of the transport container intended for transportation of spent nuclear fuel (SFN) is studied. The passage of γ-quanta from the major long-lived isotopes is examined. The radiation shields made of iron, lead and depleted uranium, which are equivalent in mass to the thickness of iron of 15 to 35 cm is considere…
The paper provides a comparative calculation of the radiation protective efficiency of various composite materials based on titanium hydride using multi-group modeling methods using the ANISN program. The calculations showed the high efficiency of titanium hydride composites with respect to neutron and gamma radiation…
In this study, the effect of recycled ceramic waste particles on the curing reaction and thermal degradation of unsaturated polyester resin has been studied kinetically. Methyl ethyl ketone peroxide and cobalt octoate were used as initiator and promotor, respectively. The porcelain powder obtained from ceramic waste w…

Simulasi mikromagnetik dilakukan pada material Co…
Abstract The surface passivation on MoS 2 and other transition metal dichalcogenides (TMDs) has been widely studied and utilized to prevent contamination and oxygen/water vapor penetration. Such approaches are mostly applied on the back-gate transistors after the formation of source/drain electrodes, while the compati…
Aims: This study aimed to eliminate metallic contaminants from drinking water by using electrospun bi-layered microfiber membranes. Background: Fast industrialization triggers environmental pollution. Heavy metals like silver, lead and aluminum are the major contaminants that are extremely toxic and accumulate in biol…
