Abstract To prepare a thin film, the block copolymer poly(TMCM‐MOE3OM)‐b‐PTMC was prepared with different segment ratios of hydrophilic moiety. The glass transition temperature of poly(TMCM‐MOE3OM)‐b‐PTMC decreased as the content of TMCM‐MOE3OM increased as expected, and it was confirmed that the graft oligo(ethylene…
Abstract Magnetic nanostructures (MNS) in their superparamagnetic form are promising materials systems for contrast enhancement in magnetic resonance imaging (MRI) and thermal‐activation therapeutics via RF heating. These biomedical applications and associated properties are very much dependent on the structure, compo…
Abstract Plasma treatment of polymers has many perspective applications in biomedical area. Carbon or carbon‐like coatings of elastic polymers are of interest. However, deformation of the polymeric substrates easily damages the modified surface. Such flaws cancel all the benefits of the treatment and should be avoided…
The determination of the most stable structures of metal clusters supported at solid surfaces by computer simulations represents a formidable challenge due to the complexity of the potential-energy surface. Here, we combine a high-dimensional neural network potential, which allows us to predict the energies and forces…
Calcium carbonate (CaCO3) is an inorganic material which has been introduced in polymeric insulation to improve the thermal and electrical properties of insulation. In this research, a comparative study was performed between unfilled polypropylene (PP) and PP nanocomposites containing 5 wt% of CaCO3 nanofiller. The el…
Porous nanoparticles are very popular because of their high surface/volume ratio; moreover, they have stronger plasmonic properties than their solid counterparts. Due to these properties, these are potential candidates in optical, or even in ophthalmological applications. We prepared porous gold nanoparticles on SiO2/…
Summary Realistic modeling of mechanical behavior of soft tissue has been recognized as an essential part for medical Internet of thing for minimal invasive surgery (MIS) training simulator. Therefore, the blockchain‐based constitutive model is crucial for mechanical response of soft tissue modeling. In this article,…
Herein, we detail an approach to accelerate the computational screening of materials for properties dictated by the kinetics of solid-state diffusion through reliably and rapidly identifying upper and lower bounds to the transition state (TS) energy through our proposed modified single iteration synchronous-transit (M…

The impact of viral infections on the central nervous system is widely known. Virus-related neuropsychiatric and neurobehavioral syndromes are caused by the distortion of cognitive, affective, behavioral, and perceptual domains. Although it is a commonly known phenomenon, the mechanism behind it is not well-understood…
Surface integrity refers to a set of characteristics of the surface and subsurface layer that have great influence on the functional performance of mechanical components under conditions of wear, corrosion and fatigue, and is determined by the manufacturing processes employed. Thus, surface treatments are used to gene…
Abstract Legacy radioactive tank waste is slated to undergo vitrification at the Waste Treatment and Immobilization Plate (WTP) using Joule-heated, ceramic-lined melters. A high-fidelity, computational fluid dynamics (CFD) model of the pilot-scale DM1200 melter has been developed to provide an understanding of the hea…
By utilizing an equivalent single conductor model, the performance of MWCNT bundle and MLGNR interconnects at global lengths is compared in terms of propagation delay and frequency stability. Results show that MLGNR interconnects can outperform MWCNT bundle counterpart (i.e. have shorter propagation delay) if properly…
We are reporting the characteristics of a glucose sensor fabricated by the use of the bio-compatible gold nanoparticles (GNPs). After synthesizing the GNPs, we have characterized them, by a UV/VIS spectrophotometer and TEM. To monitor the levels of the glucose at range of 2.8-27 mM (50-500 mg dL-1), we have used a flu…
Post-transition metal-doped quaternary chalcopyrite CZTS film has been proposed as a novel approach to improve solar energy capturing and conversion strategy. In this paper, lattice structural and optical properties of CZTS (Cu2ZnSnS4) in pure and Bi-doped conditions are theoretically investigated by employing first-p…
The complex ionic-electronic conduction in rutile has been considered for the fabrication of memristive devices with different structures. The memristive features of the device is believed to originate from the motion of the ionized oxygen vacancies within the oxide crystal. Here, we investigate the conduction mechani…
In this paper, a polarization converter (PC) in the mid-infrared frequency range is presented. The considered structure consists of a polymer of substrate backed by a gold layer and a graphene layer which laid on top of it. The designed PC works in the bandwidth of 33.67THz to 35.98THz. Furthermore, the operation freq…
A stacked patch antenna is proposed which is loaded with mushroom metamaterials. The metamaterials enable the antenna to resonate at a very low frequency while the stacked patches broaden the impedance bandwidth. A particular metamaterial antenna is demonstrated in full wave calculations. A broad bandwidth of 24.6% is…
