Abstract Fast, simple, cost‐efficient, eco‐friendly, and design‐flexible patterning of high‐quality graphene from abundant natural resources is of immense interest for the mass production of next‐generation graphene‐based green electronics. Most electronic components have been manufactured by repetitive photolithograp…
Charge-storage mechanism of free-standing MoS 2 /r-GO (r-GO = reduced graphene oxide) hybrid nanoflakes on molybdenum (Mo) foil in Na 2 SO 4 solution is elucidated for realizing a high-performance asymmetric supercapacitor (ASC). Thiourea that acts primarily as sulfur source also helps intercalating ammonium ions, whi…
The authors review the recent advances in the development of high‐strength titanium alloys. First, they summarize conventional strengthening approaches and their mechanisms, thecorresponding microstructures, and the optimized mechanical properties. Subsequently, various strengthening strategies for high‐strength titan…
Polypyrrole (PPy) nanorods (NRs) and nanoparticles (NPs) are synthesized via electrochemical and chemical methods, respectively, and tested upon ammonia exposure using Raman and X-ray photoelectron spectroscopy (XPS). Characterization of both nanomaterials via Raman spectroscopy demonstrates the formation of PPy, disp…
This chapter presents a concise treatment of diesel engine exhaust emissions and its mitigations. The working principle of the diesel engine is first given to establish the background and further to describe the influence of various parameters that affect the formation of engine exhaust emissions. The factors that inf…
Through a series of x-ray diffraction experiments, combined with first-principles calculations, we show that the nobility of platinum can be overcome, reacting with lithium under compression at room temperature. Pressures as low as 2.3 GPa lead to the synthesis of ${\mathrm{Li}}_{11}{\mathrm{Pt}}_{2}$, exhibiting the…
Abstract The goals of our study were to calculate the subcritical crack growth (SCG) parameters of two veneering ceramics stored in water or Streptococcus mutans ( S. mutans ) biofilm and remineralizing medium, with indentation flaws. Feldspar (VM7) and leucite‐reinforced (VM13) glass ceramic disks (Vita Zahnfabrik, B…
Abstract One of the important issues of molecular spintronics is the control and manipulation of charge transport and, in particular, its spin polarization through single-molecule junctions. Using ab initio calculations, we explore spin-polarized electron transport across single benzene derivatives attached with six d…
The development of natural-based corrosion inhibitors has increasingly become an important research objective. Herein, we report the potential use of two natural furocoumarins namely, Bergamottin (FCC) and Isopimpinellin (FC-M) for the corrosion protection of mild steel (MS) in 1.0 M HCl. Corrosion inhibitory activiti…
Diamond crystals from the Istok (25 crystals) and Mayat (49 crystals) placers were studied using the EPR-, IR-, and luminescence methods. The total content of impurity nitrogen in forms of A-, B-, and C (P1)-centers ranges from 50 to 1200 ppm. According to the EPR-spectroscopy, the presence of nitrogen C(P1), N3V nitr…
Purpose This study aims to investigate rheological and extrusion behavior of thermosetting epoxy resins, which to find the universal property and printing parameters for extrusion-based rapid prototyping applications. Design/methodology/approach The thickener proportion greatly influences its viscosity and rheological…
This study aimed to investigate the effects of Cu addition on the properties of the 10CrNi3MoV steel weld metals prepared in the laboratory according to the flux-cored arc welding (FCAW) method. Specifically, the 10CrNi3MoV steel FCAW joints had been fabricated based on the as-prepared flux- cored wires after adding v…

Abstract In the present study, electron beam welding bead-on-plate of electrolytic pitched copper (ETP-Cu) plate was carried out to study the behavior of different defects formed in the weld by varying the beam oscillation amplitudes. The defects like spattering, spiking and porosity were considered in this study. Spa…
Purpose The purpose of this study is to demonstrate that using appropriate values for fictitious parameters is very important in dynamic relation methods. It will be shown that a better scheme can be made by modifying these terms. Design/methodology/approach Former research studies have proposed diverse values for fic…
Abstract The possibility of using induction sensors for fixing hypersonic particles in time in the simulation of collisions of high-velocity metal particles with targets is considered. A design of the induction sensor for starting the recording equipment in the air atmosphere is presented. Experimental results on the…
In this work, one kind of biocompatible and all-in-one dual-modal nanoprobe, based on Au nanoparticles and NIR emissive semiconducting fluorescence polymers, was developed by the one-step solvent-mediated self-assembly method for in vivo X-ray computed tomography (CT) and fluorescence bioimaging for the first time. Af…
Abstract An extremely simple noncontact method for measuring the resistivity of metals at high temperatures is proposed. The essence of this method is to measure the electromotive force induced by a high-frequency electromagnetic field in two circular circuits of different diameters, which are placed coaxially in the…
The purpose of the study was to synthesize MgO nanomaterials using sol-gel method with ethanol as solvent and to perform structural analysis of the products. Mg-oxalate was initially prepared prior magnesium acetate. Magnesium acetate dissolved in ethanol, and the oxalic acid added to adjust pH until gel phase formed.…
