The probabilistic aspects of multiscale modeling of the fracture of heterogeneous structures are considered. An approach combining homogenization methods with phenomenological and numerical models of fracture mechanics is proposed to solve the problems of assessing the probabilities of destruction of structurally hete…
Single crystals of SmAl3(BO3)4 were synthesized by the group growth on seeds method. The crystal structure was solved using a single-crystal experiment and the purity of the bulk material was proved by the Rietveld method. This borate crystallizes in the monoclinic C2/c space group with unit-cell parameters a = 7.2386…
Li2FeMn3O8 (LFMO) nanocomposite material for Li-ion battery is synthesized using chemical combustion method. To fabricate a hybrid nanostructure electrode, LFMO is coated on tin oxide (SnO2) nanorods (NR), which is grown using a vapor-liquid solid (VLS) technique on a steel substrate. The surface morphology of the hyb…
Pathogenic bacteria are those bacteria that produce illness. These bacteria can cause diseases and infections when they get in the body of a healthy host and begin to reproduce very fast in the host body. For these bacterial diseases, researchers have developed antibacterial agents to aid infectious diseases, which ar…
The Bauschinger effect is one of the fundamental properties of most metal alloys exposed to plastic deformation under non-monotonic loading. Development of the methods for quantifying this effect is one the important issues of the theory of plasticity. Calculation of the parameter characterizing the aforementioned eff…
Air pollution is a growing problem worldwide, reason for seeking more efficient methods to prevent exposure to contaminated air.Air filters must have the ability to effectively remove extremely small quantities of hazardous materials from the air, without causing excessive pressure drops, all at acceptable price condi…
Purpose of the study: Microalgae with better carbon sequestration potential, higher biomass, and lipid productivity in comparison to terrestrial counterparts is emerging as a viable sustainable alternative to fossil fuels. Diatoms, a subgroup of a broader category of microalgae are well-known for their role as a bio-i…
Abstract The cavitation bubbles that collapse in the hydraulic machinery can cause damage to the structure and the internal wall. In order to find feasible preventive measures, the mechanism of cavitation bubble collapse needs to be thoroughly studied. However, the influence of the initial radius or the interaction be…
Background: Aedes mosquitoes are the most important group of vectors having ability of transmitting pathogens including arboviruses that can cause serious diseases like Chikungunya fever, Dengue fever and Zika virus in human. Biosynthesis and the use of green silver nanoparticles (AgNPs) is an important step in the se…
A comparative analysis of current methods for determination of aromatic hydrocarbons in the components of diesel fuel revealed that IR spectrometry appeared to be the most optimal method for operational control of the content of aromatic hydrocarbons in medium distillate products of the hydrogenation process. We devel…
Adsorption of gemfibrozil (GF) from aqueous solution by highly/lowly graphitized carbon black (GCB-H/GCB-L) was investigated by batch and fixed-bed experiments. Results showed that the adsorption of GF onto GCB greatly depended on solution pH and graphitization of carbon. The pseudo-second-order kinetic model was foun…
Double compression tests are carried out to investigate the microstructural evolution and precipitation behavior of Nb–Ti microalloyed carbide‐free bainitic steel under different finish rolling conditions. With decreasing finish rolling temperature and increasing finish rolling deformation, the area fraction of lath b…
The unique structure of two-dimensional molybdenum disulfide (MoS2) with rich active sites makes it a promising catalyst, whereas it also brings structural instability. Surfactant-assisted synthesis of MoS2 can be regarded as a simple way to regulate the microstructure. In this work, the surfactant additives were adop…
Cellulose acetate blend membranes in this study synthesized from cellulose acetate (CA) of rice husk and NaA zeolites (Z) with N,N’-Methylene bis acrylamide (MBA) as cross-linker agent and gamma-rays from cobalt-60 source as a reaction initiator. Application of the membrane was carried out to increase the concentratio…
This study takes the Nanfei River as an example, using a hydrodynamic and water quality model based on MIKE11 to predict the effect of graphene photocatalysis on urban rivers. The effect of water quality improvement in the Nanfei River was simulated under three different scenarios (treatment plant upgrade, use of grap…
Spectroscopic and photovoltaic properties of composites of purified and subsequently fluorinated single‐walled carbon nanotubes (F‐SWCNTs) with conjugated polymer poly(3‐hexylthiophene) (P3HT) are tested. Adding cyclohexanone into o‐dichlorobenzene solution of P3HT and F‐SWCNTs significantly affects the composite morp…
A series of 5 wt% NiO-xP-Al2O3 with different phosphorus loading contents (x = 0, 5, 15 and 20 wt%) were prepared by a modified sol-gel method. A significant promotional effect of phosphorus on NiO-Al2O3 in CO2 hydrogenation is observed. All the catalysts reach the highest conversion at 600 °C with 61.54 %, 62.89 %, 6…
The plastic working of metallic materials is one of the most efficient and important manufacturing technologies used in industry today [...]
Cancer is one of the killers endangering human health and its treatment has always been a focus of the medical community. For anticancer drugs, water‐soluble porphyrin and Schiff bases have always been of interest. We report here three Cu(II)‐based complexes functionalized by water‐soluble cationic porphyrin and hydra…
Summary Antimicrobial essential oil nanoemulsions have been wildly applied in plant sterilisation. Here, a turmeric oil (TO) oil‐in‐water (O/W) nanoemulsion was developed to understand the antifungal mechanism between TO and Podosphaera xanthii ( P. xanthii ), simulating a moisture evaporation after spraying TO nanoem…
