Nonequilibrium molecular dynamics simulations are reported to investigate the influence of different atomistic water models on the predicted flow behavior in carbon nanotubes (CNTs) with diameters between 0.81 nm and 1.9 nm. The comparison was made using rigid three-site [simplified point charge (SPC), extended SPC (S…
A novel flexible transparent electrode (TE) having a trilayer-stacked geometry and high optoelectronic performance and operational stability was fabricated by the spin coating method. The trilayer was composed of an ultrathin graphene (Gr) film sandwiched between a transparent and colorless polyimide (TCPI) layer and…
The need for affordable systems that are capable of regulating the temperature of living or storage spaces has increased the interest in exploring phase change materials (PCMs) for latent heat thermal energy storage (LHTES). This study investigates n-nonadecane (C19H40) and n-eicosane (C20H42) as alkane hydrocarbons/p…
The current research was done to investigate the effect of wetting-drying cycles, time, and clay mineralogy on K fixation capacity of highly calcareous soils. In order to conduct the study, eight soil samples were collected. The samples were treated with different concentrations of K including 200 (K1), 400 (K2) and 8…
Abstract Amino‐functionalized Fe3O4@carbon microspheres (NH2−Fe3O4@C) were prepared and the electrochemical sensor was constructed using NH2−Fe3O4@C modified glassy carbon electrodes (GCE) to determine toxic heavy metals in aqueous solution. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X…
The main types of distresses in asphalt mixtures are rutting, fatigue, and thermal cracking at various performance temperatures. One of the beneficial approaches for improving their strength related to these failures is modifying the characteristics of bitumen by additives. The use of polymers in modifying bitumen pro…
Chirality transfer from self-assembly of achiral titanyl phthalocyanine (TiOPc) to its top-sitting TiOPc molecule has been successfully achieved. The TiOPc molecules first assemble into a porous network on Au(111) that contains periodic chiral voids, each being fenced by four axially rotating TiOPc molecules in upward…
Abstract In this study, magnetic iron oxide/graphene oxide (Fe 3 O 4 /GO) nanocomposites were developed for removal of cadmium ions (Cd 2+ ) from water, which could be effectively separated from the solution owing to its superparamagnetic property. The Fe 3 O 4 /GO nanocomposites were fabricated by co-precipitation me…
The spatiotemporal sensing of specific cationic and anionic species is crucial for understanding the processes occurring in living systems. Herein, we developed new fluorescence sensors derived from tetrapyrazinoporphyrazines (TPyzPzs) with a recognition moiety that consists of an aza-crown and supporting substituents…
A modular linear doubly salient machine with dual-PM in the primary yoke and slot openings is proposed in this paper. First, the machine topology is introduced, where the PMs are employed in both the primary yoke and slot openings. The magnetic fluxes excited by the PMs in the slot openings pass through the air gap an…
When conjugate molecules are self-assembled on the surface of semiconductors, emergent properties resulting from the electronic coupling between the conjugate moieties are of importance in the interfacial electron-transfer dynamics for photoelectrochemical and optoelectronics devices. In this work, we investigate the…
To analyze the effect of lithium and microstructure on the pitting corrosion behavior of aluminum alloys, three types of aluminum alloys were studied via scanning electron microscopy, transmission electron microscopy, electrochemical polarization, and by immersion tests coupled with in-situ observation of pitting and…
Novel materials with nanostructures are effective in controlling the physical properties needed for specific applications. The use of active and sensing materials is increasing in many applications, such as gas sensing. In the present work, we attempted to synthesize incorporated Cu2+ into the SnO2 matrix as CuxSn1−xO…
A new counter electrode which makes use of reduced graphene oxide (rGO), poly (3,4-ethylenedioxythiophene) (PEDOT) and aluminium oxide (Al 2 O 3 ) was developed to enhance the performance of dye-sensitized solar cell (DSSC) device in replacing platinum as a counter electrode. PEDOT/rGO-Al 2 O 3 was fabricated through…
Abstract The huge market demand for organic light‐emitting diodes (OLEDs) has attracted a significant number of researchers to explore robust and cheap luminescent materials for application in high‐performance and low‐cost OLEDs. This concept article presents a new class of organic luminescent materials which demonstr…
reserves. To fabricate high-performance NIC electrode material, a hydrothermal method was proposed to synthesize sulfur-doped reduced graphene oxide (SG), which exhibited unique layered structures and showed excellent electrochemical properties with 116 F/g capacitance at 1 A/g as the cathode of NICs from 1.6 V to 4.2…
Abstract This paper addresses the resistive switching behavior in yttrium oxide based resistive random access memory (RRAM) (TiN/yttrium oxide/Pt) devices. We report the coexistence of bipolar and unipolar resistive switching within a single device stack. For bipolar DC operation, the devices show gradual set and rese…
Nanostructured materials producing structural colors have great potential in replacing toxic metals or organic pigments. Electrophoretic deposition (EPD) is a promising method for producing these materials on a large scale, but it requires improvements in brightness, saturation, and mechanical stability. Herein, we us…
The scope of the environmentally benign direct C–H arylation polymerization (DARP) process is validated and significantly extended in the synthesis of a high-performance benzodithiophene-based copolymer series, PBDT(Ar)-FTTE, with previously untested and systematically varied heteroaryl (Ar) substituents. Bulk-heteroj…
Currently available scaffolds for tissue repair have shown very limited success, so many efforts have being put in the development of novel functional materials capable of regulating cell behavior and enhance the tissue healing rate. Piezoelectric materials, as zinc oxide (ZnO), can be a very interesting solution for…
