Abstract This present study describes a pencil graphite electrode surface covered with Cu(II) and Fe(III) complexes based on Salophen derivative Schiff bases in acetonitrile solution containing LiClO4 as a supporting electrolyte. Cyclic voltammetry method was used for the surface modification procedure with 25 cycle a…
Abstract The avoidance of failures during the fabrication or operation of petrochemical reactors made of creep-resistant, low-alloy steels as 13CrMoV9-10 requires still research despite over 60 years of international investigations in the field of stress relief cracking. The quality of modern base materials and filler…
The Ni-metal-organic frameworks microspheres (Ni-BTC) were prepared and used directly to construct non-enzymatic glucose sensors. The Ni-BTC sensors displayed much higher glucose sensing performance than that of Ni-MOFs derived NiO, which showed wide detection regions of 5–3000[Formula: see text][Formula: see text]M a…
Abstract There is still a growing interest in CO2 conversion into useful compounds. Plasma technology is a highly promising alternative due to its non-equilibrium nature, crucial for CO2 dissociation processes. In this study we present, the non-thermal plasma-assisted catalytic CO2 reduction to CO on 2D Zn-containing…
The effect of cobalt substitution with nickel was investigated for the Fischer–Tropsch synthesis reaction. Catalysts having different Ni/Co ratios were prepared by aqueous incipient wetness co-impregnation, characterized, and tested using a continuously stirred tank reactor (CSTR) for more than 200 h. The addition of…
Organometallic compounds embedded in thin films are widely used for Organic Light-Emitting Diodes (OLED), but their functionalities are strongly correlated with the intrinsic properties of those films. Controlling the concentration of the organometallics in the active layers influences the OLED performances through th…
To prepare surfaces with stable anti‐icing properties, square‐column micro/nanocomposite structures were fabricated using wire‐cut electrical discharge machining. Smooth and hydrophobic/superhydrophobic surfaces were tested for wettability and were subjected to mechanistic analysis. Droplets were found to produce an ‘…
We present a predictive model for line-to-line dielectric reliability that takes variability into account. The lifetime distribution is obtained by performing series-parallel reliability computations, starting from the failure distributions of single dielectric unit cells, assumed to be Weibull. The electric field in…
Solvent polarization around a polar solute molecule plays an essential role in determining the electronic and thermodynamic properties of solutions. In this study, a solvent-polarizable model in response to solute polarization is proposed, which is coupled with a three-dimensional reference interaction-site model theo…
Bimodal nanostructured (NS) metals realize the superior strength due to the strengthening of nanograined (NG) matrix, whereas their high ductility arises from the toughening of coarse‐grained (CG) inclusions. Their overall strength and ductility can be influenced by 1) the fracture properties of CG and NG phases, 2) t…
Many high-strength composite materials have been developed for aircraft structures. GLAss fiber REinforced aluminum (GLARE) is one of the high-performance composites. The review of articles, however, yielded no study on the impact damage of heated GLARE laminates. This study, therefore, aimed at developing a numerical…
Abstract The sucrose isomerase SmuA from Serratia plymuthica efficiently catalyses the isomerisation of sucrose into isomaltulose, an artificial sweetener used in the food industry. However, the formation of a hygroscopic by‐product, trehalulose, necessitates additional separation to obtain a crystalline product. Ther…
An ionization sensor based on suspended carbon nanotubes (CNTs) was presented. A suspended CNT beam was fabricated by a low-temperature surface micromachining process using SU8 photoresist as the sacrificial layer. Application of a bias to the CNT beam generated very high non-linear electric fields near the tips of in…
Abstract Specific molecular recognition of γ‐cyclodextrin (γ‐CD) by the cationic hexanuclear niobium [Nb6Cl12(H2O)6]2+ cluster complex in aqueous solutions results in a 1:1 supramolecular assembly {[Nb6Cl12(H2O)6]@γ‐CD}2+. NMR spectroscopy, isothermal titration calorimetry (ITC), and ESI‐MS were used to study the inte…
Zero-mode waveguide (ZMW) nano-apertures milled in metal films were proposed to improve the Förster resonance energy transfer (FRET) efficiency and enable single-molecule FRET detection beyond the 10 nm barrier, overcoming the restrictions of diffraction-limited detection in a homogeneous medium. However, the earlier…
The gastrointestinal disease of ruminants is clinically known as Johne’s disease (JD) and is caused by Mycobacterium avium subspecies paratuberculosis (MAP). An accumulative effect by insensitive diagnostic tools, a long subclinical stage of infection, and lack of effective vaccines has made the control of JD is diffi…
The formation of amyloid structures has traditionally been related to human neurodegenerative pathologies and, in recent years, the interest in these highly stable nanostructures was extended to biomaterial sciences. A common method to monitor amyloid growth is the analysis of Thioflavin T fluorescence. The use of thi…
Abstract The THz and sub-THz polarized Raman response was measured in tetragonal and cubic phases of single domain BaTiO 3 crystal. A large peak was detected at very low wavenumber, within a scattering geometry in which all phonon lines are Raman inactive. It lies below 700 GHz in the whole temperature range of the te…
2-Keto-L-gulonic acid (2-KLG) is the direct precursor for the production of L-ascorbic acid (L-Asc) on industrial scale. Currently, the production of L-Asc in the industry is a two-step fermentation process. Owing to many unstable factors in the fermentation process, the conversion rate of L-sorbose to 2-KLG has remai…
Analytical models are widely employed in the design of electromagnetic devices. This study presents a flux‐tube model for axial‐flux eddy‐current couplers with surface magnets. Thanks to the developed three‐dimensional magnetic equivalent circuit, the proposed model is able to handle complex geometries and take into a…
