Nano-sized tetragonal BaTiO₃ (BT) particles that are well dispersed in solution are essential for the dielectric layer in multilayer ceramic capacitor technology. A hydrothermal process using TiCl₄ and BaCl₂, as source of Ti and Ba, respectively, or the precursor TiO₂ as seed for the formation of BT, and poly(vinylpyr…
Abstract Controllable and repeatable crystal imperfection modulation engineering (CIME) is important for the development of semiconductor science and technology. However, for wide band gap semiconductors (WBGSs), there still lacks universal and reliable CIME. Here, based on the general idea of chemical composition com…
The effect of electro‐slag refining (ESR) processing with niobium inoculation and increased carbon content of high strength low alloy steel was examined using electrochemical corrosion and nanomechanical test methods. The results indicate that ESR processing with niobium inoculation effectively improves the corrosion…
Abstract In this study, a direct sulfidation reaction of ammonium perrhenate (NH 4 ReO 4 ) leading to a synthesis of rhenium disulfide (ReS 2 ) is demonstrated. These findings reveal the first example of a simplistic bottom-up approach to the chemical synthesis of crystalline ReS 2 . The reaction presented here takes…
Thin films of antiperovskite Mn3GaN1-x were grown on MgO (001) substrates by reactive magnetron sputtering, and their structural, magnetic, and magneto-optical properties were systematically investigated. It was found that the combination of the deposition rate and the N2 gas partial pressure could produce epitaxial f…
The monochromatic photoemission from diamondoid monolayers provides a new strategy to create electron sources with low energy dispersion and enables compact electron guns with high brightness and low beam emittance for aberration-free imaging, lithography, and accelerators. However, these potential applications are hi…
Abstract Thioether‐based acrylate block polymers are conveniently prepared via reversible addition–fragmentation chain‐transfer polymerization, and further combined with the merit of reversible metal–thioether coordination to fabricate a new type of “smart” thermoplastic materials. This metal/polymer hybrid architectu…
In this work, we point out that the width and the nature of the magnetic phase transition, TC value, and as well as magnetocaloric effect in La0.7-xSmxCa0.3MnO3 compounds can be easily modified through Sm-doped into La-site. With an increasing Sm concentration, a systematic decrease in the magnetization, TC, and magne…
Atmospheric corrosion near the coastal areas of Karachi is a subject of great interest where seasonal variation of north Arabian Sea, high onshore activities, high levels of atmospheric pollutants, high humidity, and low temperature range affects the service life of structural materials. Mild steel test coupons were e…
ABSTRACT The synthesis of negatively charged magnetite nanoclusters grafted with poly(acrylic acid) (PAA) and their application as reusable nanosupports for adsorption with antibodies and antigens are presented in this article. They were facilely prepared via the free‐radical polymerization of PAA in the presence of f…
Microsynchrotron radiation X-ray fluorescence spectrometry (μ-SR-XRF) is an X-ray procedure that utilizes synchrotron radiation as an excitation source. μ-SR-XRF is a rapid, nondestructive technique that allows mapping and quantification of metals and biologically important elements in cell or tissue samples. Generall…
The focus of the present work is to investigate the bonding characteristics of vanadium oxide species to different oxygen functional groups on multiwalled carbon nanotubes (MWCNT). Atomic layer deposition (ALD) was used to deposit atomically dispersed vanadium oxide species on MWCNT. To generate atomically dispersed v…
A main difficult task in batch crystallization is to control the size distribution of crystal products. Complexity and highly nonlinear dynamic behavior directly affect to model-based control strategies which heavily depend on the rigorous knowledge of crystallization. In this work, neural network-based model predicti…
Abstract Herein a complete characterization of single TiO 2 nanotube resonator was reported for the first time. The modal vibration response analysis allows a non-invasive indirect evaluation of the mechanical properties of the TiO 2 nanotube. The effect of post-grown thermal treatments on nanotube mechanical properti…
The irreversible transformation from an icosahedral quasicrystal (i-QC) CaAu 4.39 Al 1.61 to its cubic 2/1 crystalline approximant (CA) Ca 13 Au 56.31(3) Al 21.69 (CaAu 4.33(1) Al 1.67, Pa 3̅ (No. 205); Pearson symbol: cP 728; a = 23.8934(4)), starting at ∼570 °C and complete by ∼650 °C, is discovered from in situ, hi…
Monolithic Microwave Integrated Circuit (MMIC) have major impact on the development of microwave communication technology. Transition metal based ferromagnetic nano-wired (FMNWs) substrate are of special interest in order to fabricate these MMIC devices. Their saturation magnetization is comparatively higher than ferr…
In this work we recover the Oseen–Frank theory of nematic liquid crystals as a [Formula: see text]-limit of a particular mean-field free energy as the sample size becomes infinitely large. The Frank constants are not necessarily all equal. Our analysis takes place in a broader framework however, also providing results…
The search for and study of exotic quantum states in novel low-dimensional quantum materials have triggered extensive research in recent years. Here, we systematically study the electronic and magnetic structures in the newly discovered two-dimensional quantum material C 3 N within the framework of density functional…
A study of the mechanical behavior of isotactic 1,2-poly( E -3-methyl-1,3-pentadiene) (iP3MPD) and of the structural and morphological transformations that take place upon stretching is presented. Amorphous samples do not show viscous flow but show high ductility, strain hardening, and elastomeric behavior. An unusual…
Complicated magnetic phase transitions and Large magnetocaloric effects (MCEs) in RCoGe (R=Tb, Dy) compounds have been reported in this paper. Results show that the TbCoGe compounds have a magnetic phase transition from antiferromagnetic to paramagnetic (AFM-PM) at TN∼16 K, which is close to the value reported by neut…
