Preparation, characterization, and stability evaluation of gold nanoparticles stabilized by ω-sulfonylated alkylsulfanylaniline have been described. The particle solution was obtained by the spontaneous reaction of HAuCl4 and ω-sulfonylated alkylsulfanylaniline in boiling water. It showed a deep red color, owing to su…
Chitin, the second most abundant biomolecule on earth after cellulose, was used to prepare 25-40 nm diameter chitin nanofibers (CNFs) in wet acidic condition from crab shells. Using CNFs suspension, neat CNFs and gold nanoparticles (Au NPs) embedded 70 m thin printable films were prepared. Electrical and optical prope…
The insulation deterioration of mining dry‐type transformer is always accompanied with partial discharge (PD). The assessment accuracy of transformer insulation performance is directly affected by the authenticity of the PD signal. Based on the ensemble empirical mode decomposition (EEMD) and combining the principle o…
A p-type oxide is a key element for transparent thin-film transistor applications. Among the various p-type oxides currently available, SnO x deposited by sputtering is the subject of interest in this study for high-performance and reliable thin films. A tin target or a tin oxide target is typically used to fabricate…
Generally, torsion deformation has been recognized as a method of severe plastic deformation (SPD) to obtain a higher shear strain. The effect of strain reversal on the microstructure and mechanical properties was investigated using commercially Ti-6Al-4V alloy by twisting the rods with different effective strain ampl…
The electrochemical corrosion of the FV520B stainless steel for natural gas compressor impeller is studied by means of the uniform experimental method. The electrochemical corrosion potential, current density and Tafel slope of the material are measured, and the polarization resistance is solved. The experimental resu…
Nanomaterials-based diagnostics have tremendous advantages over other conventional diagnostic systems in terms of sensitivity, specificity, and portability owing to the unique intrinsic properties of nanomaterials. Thus, there is a substantial need to develop and employ a broad spectrum of nanomaterials for biological…
The microstructure of two centrifugally cast ductile iron pipes with a diameter of DN100 and wall thickness of 6 mm was studied. After casting, the pipes undergo annealing and finishing with anticorrosion coatings. Tensile tests were performed using longitudinal samples, cut in an appropriate manner from the pipe wall…
Relationships between Ligand Structure and Complex PropertiesGd III -based contrast agents for MRI are used in approximately 30% of MRI exams. 1 Although the FDA-approved contrast agents are among the safest drugs on the market, their core, the Gd III ion, has a 50% lethal dose, (LD 50 ) around 0.1-0.2mmol kg À1 . 2 T…
The development of modern industry is aimed at reducing the consumption of materials, improving the technological properties of products. The products made of expensive metals and scarce alloys should be produced as combined, with the base consisting of the cheapest materials, and on the working surface of fusing allo…
The article presents issues related to the joining of hard-to-join metals such as aluminium, magnesium and titanium alloys as well as discusses problems accompanying the joining of the above-named materials and indicates the possible use of adhesive bonding when joining them. The article pays particular attention to a…
Engineered nanoparticles (ENPs) are being incorporated into many fields, from paints, automobile, consumer products to biology and medicine. Although there is an increase in the prevalence of ENPs, there is a dearth of knowledge of the impacts of ENPs on human and environmental health. The potential toxicity of ENPs h…
Environmental protection and sustainable agricultural production require the use of inexpensive and environmentally acceptable soil supplements. Objectives of this study were to investigate the influence of the addition of the natural zeolite ? clinoptilolite (NZ) and its iron(III)-modified form (FeZ) on the potassium…
at 0 V vs. RHE, which is 58.3 and 2.3 times as large as that of the planar wafer and the NPs reported by our group in our previous work respectively) and a lower onset potential (-0.58 V vs. RHE, shifting negatively nearly 300 mV compared with its counterparts in the previous work). Besides the excellent light-trappin…
F NMR and X-ray crystallography, but did not perturb function. This data unequivocally demonstrates that the concentration of the metal fluoride complexes is equivalent to the concentration of enzyme and ligand in the TSA complex in aqueous solution.
Code validation against experimental data is vital in building confidence for the use of simulation software in modeling and system design. Temperature data is of particular interest in the study of hypervelocity impact, however the experimental measurement of temperature in such a regime is difficult. Novel developme…

Calcium carbonate crystallisation on surfaces has been studied extensively due to its prominence in biomineralisation, but the role of surface charge in nucleation and growth is not well understood. We have employed potential-controlled Highly Oriented Pyrolytic Graphite (HOPG) surfaces to demonstrate the significant…

In this paper, we develop and assess a numerical model for simulating hypervelocity impacts (HVI) with a Discrete Element Method (DEM). The model consists of discrete spheres interacting via simple potentials. We determine the material parameters empirically by comparing them to recent HVI experiments. Using this mode…
