The synthesized chiral ( R )- and ( S )-2-(1-hydroxyethyl)pyridine ligands ( R / S -mpm) were introduced to self-assembled Co II -[W V (CN) 8 ] and Ni II -[W V (CN) 8 ] magnetic systems giving a remarkable series of four enantiopure cyanido-bridged clusters, {M II [M II ( R / S -mpm)(MeOH)] 8 [W V (CN) 8 ] 6 }·14MeOH…
A thorough study of the structural, electronic, and hydrogen-desorption properties of β- and γ-MgH2 phases substituted by selected transition metals (TMs) is performed through first-principles calculations based on density functional theory (DFT). The TMs considered herein include Sc, V, Fe, Co, Ni, Cu, Y, Zr, and Nb,…
Abstract The occurrence and spread of halophilic diatom taxa in freshwater lotic ecosystems are influenced both by natural processes and anthropogenic pollution. Diatom assemblages were regularly monitored in lowland lotic systems in Hungary (Central Europe) during the unusually dry year of 2012. Highly pronounced cha…
Urea precipitation method has been developed as an important approach for the preparation of inorganic particles with defined morphology and composition. In present work, we provide survey of the technological developments and achievements mainly on the application of the urea precipitation method in preparation of ad…
Because of persistent economic pressure on cost reduction, inorganic fillers such as precipitated calcium carbonate (PCC) have become increasingly economically attractive in the papermaking process. The increase of filler level in paper can be achieved by adding it to pulp prior to the headbox, either as individual fi…
The design of energy-efficient electrical machines requires the accurate estimation of iron loss. There are minor hysteresis loops in the case in which a flux density waveform includes higher harmonics, and it is possible that the conventional iron loss calculation methods do not accurately estimate minor-loop loss. T…
With the aim of understanding recent experimental data concerning molecular doping in WS 2 -based FET gas sensors, we have investigated the interaction of NH 3 and H 2 O molecules with monolayer WS 2 , by means of first-principles calculations. The structural relaxations and total energy calculations are performed to…
Water absorption and mechanical performance of the injection‐molded hybrid composites prepared from different ratios of two polymer blends (57 wt%), two compatibilizers (3 wt%), and two wood species (40 wt%) were investigated. The ratio of polypropylene and high‐impact polystyrene (HIPS) gradually increased in the ble…
In this work, an innovative experimental platform to study the nucleation behavior of an active pharmaceutical ingredient (API) using a gas-segmented flow produced by a microfluidic T-junction device with fine perfluoroalkoxy alkane (PFA) tubing is presented. In the experiments, a continuous airflow was used to segmen…
Sol–gel chemistry is a powerful tool for the synthesis of porous or nanocrystalline structures of a wide range of materials. The morphology and composition of the final product can be strongly dependent on the mechanism that operates during the heating step, as has been demonstrated in many investigations of binary, t…
High coercivity MnBi alloy is a promising candidate as earth abundant permanent magnet for energy-critical technologies. We report here a new metal-redox method to synthesize colloidal MnBi nanoparticles, exhibiting a saturation magnetization of 49 emu/g and coercivity of 15 kOe. It is shown that the magnetic properti…
The use of hexagonal boron nitride (h-BN) in microfluidic and nanofluidic applications requires a fundamental understanding of the interaction between water and the h-BN surface. A crucial component of the interaction is the binding energy, which is sensitive to the treatment of electron correlation. In this work, we…
Synthetic materials are known to initiate clinical complications such as inflammation, stenosis, and infections when implanted as vascular substitutes. Collagen has been extensively used for a wide range of biomedical applications and is considered a valid alternative to synthetic materials due to its inherent biocomp…
Using first-principles studies, we investigated the width-dependent magnetic properties of armchair black phosphorene nanoribbons (APNRs) by controlling the electron charge doping. In the unrelaxed APNRs the antiferromagnetic coupling between two phosphorus atoms in the same edge was found. However, the edge magnetic…
In this paper, we have investigated the static metrics and switching attributes of graphene nanoribbon field-effect transistors (GNR FETs) for scaling the channel length from 15 nm down to 2.5 nm and GNR width by approaching the ultimate vertical scaling of oxide thickness. We have simulated the double-gate GNR FET by…
In this study, carvacrol-loaded human serum albumin (HSA) nanoparticles were developed and characterised. Nanoparticles were prepared by desolvation and emulsion/desolvation methods. Encapsulation efficiency (EE%) and loading capacity (LC%) of nanoparticles prepared by desolvation method were 48.4 and 45.1%, respectiv…
The increasing use of Nanoparticles (NPs) in a wide range of applications has led to a rising concern on the possible toxicological effects that this use may have on human health and the environment. Since experimental toxicity evaluation for the different types of NPs already available, is often expensive and time co…
Encapsulation and full retention of small molecular weight active ingredients is a challenging task that remains unsolved by current technologies used in industry and academia. In particular, certain everyday product formulations provide difficult environments in which preventing active leakage through capsule walls i…
Porous calcium carbonate particles were synthesized by adding solutions of Ca 2+ to solutions of CO 3 2– containing polymeric additives. Under optimized conditions well-defined aggregates of the anhydrous polymorph vaterite formed. A typical sample of these micrometer-sized aggregates had a pore volume of 0.1 cm 3 /g,…
Few layer graphene systems such as Bernal stacked bilayer and rhombohedral (ABC-) stacked trilayer offer the unique possibility to open an electric field tunable energy gap. To date, this energy gap has been experimentally confirmed in optical spectroscopy. Here we report the first direct observation of the electric f…
