Abstract Modulating the n- and p-type interfacial charge transport properties of the metal–semiconductor interface is vital to realizing high performance two-dimensional material nanodevices and is still a significant challenge. Here, a boron nitride (BN)-graphene lateral heterostructure (LH) was used as the interfaci…
Abstract Smart chromic elastomers exhibiting multistimuli responsiveness are of interest with regard to the development of sensors, optical data storage, and smart wearable devices. We report a new design of Cu nanoclusters (Cu NCs) containing polymeric elastomer film, showing reversible fluorescence ON/OFF when subje…
In this study, the effects of Na doped on the structure, morphology, and optical properties of the ZnO films deposited on glass substrate were investigated. The films were synthesized on glass substrates via a simple chemical method. Undoped and Na-doped ZnO films were obtained from an aqueous solution of the Zinc nit…
Shock Wave / Boundary Layer Interaction is an important issue that should be taken into account when studying inlet design. Bleed holes have traditionally been used to remove the lower momentum part of the boundary layer to avoid separation from adverse Shock Wave / Boundary Layer Interaction. In this study, modeling…
In this article, we demonstrated the fabrication of micro-supercapacitors by photolithography technology and liquid-air interface self-assembly method. A large-area uniform film with a thickness of 18 nm was fabricated by the modified liquid-air interface self-assembly, and a narrow finger gap, which was 30 μm, was ma…
Lyotropic chromonic liquid crystals (LCLCs) combine a very high packing density (intramolecular separation is about 3.4 Å within aggregates) with an ability to form ordered structures that are transferable from a water solution to a dry film. We show that the electric current in a dry film of LCLC aggregates is sensit…
Abstract This study evaluates the potential offsite radiological hazards by calculating total effective dose equivalent (TEDE) and excess cancer risk if onsite soil contamination occurs at the proposed Rooppur Nuclear Power Plant (RNPP) site, Bangladesh. The assessment has been performed assuming a hypothetical soil c…
Experiments were performed on the atomization of Carbopol-water gels of compositions in the range 0.10--0.30 gellant wt.% on a like-on-like jet impingement configuration. Analysis indicates two primary modes of sheet breakup: perforation-driven and wave-driven. While perforation-driven breakup is not seen for the lowe…
The effects of the chemical nature of an interface are one of the key parameters which can affect self-assembly and rheological behavior. To date, several studies have reported self-assembled structures and rheological behaviors in the development of various functional materials. In this study, we investigated the sel…
With the development of high-power light-emitting diodes (LEDs), the heat flux density of devices has continued to increase, which, in turn, requires the development of increasingly effective methods of heat dissipation to control the working temperature of LEDs. Due to their impressive performance in solid refrigerat…
Abstract We study the problem of a thin liquid film falling down an inclined slope. We use a simplified model to study the evolution and morphology of the solitary waves on a thin film with a periodic forcing at the inlet. In recent work by Denner et al (2016 Phys. Rev. E 93, 033121), the regime for high Re was studie…
Infiltration effect is an important factor for the preparation of ideal CF/Al composites by liquid infiltration method, so it is necessary to study the infiltration law of aluminum alloy in carbon fiber preform to obtain composite with sufficient and uniform infiltration effect. Through theoretical analysis and calcul…
Montmorillonite K-10 clay (MMT) was surface-modified by sodium dodecyl sulfate (SDS) and grafted with KH-550 coupling agent to construct "Hy-MMT" organic modified structure in one step with hydrothermal-assist. Different sustained release systems were prepared through changing the temperature during the hydrothermal p…
Abstract Compositionally graded alloys can realize multiple conflicting properties in the same part, but the formation of secondary phases can often lead to cracks or deleterious properties. In prior work, a computational methodology was presented that can design compositional gradients to avoid these phases at any te…
Used cooking oil is generated as a byproduct during frying process. It cannot be reused for cooking process due to health issues such as cancer and other digestive disorders. Alternative strategy is utilization of this waste cooking oil for production of poly-3-hydroxybutyrate (PHB) a biopolymer which can be used as a…
The thermal welding process of Ag nanoparticles was studied by molecular dynamics using embedded atoms method (EAM), and the melting point of Ag nanoparticles was analyzed by radial distribution function (RDF) and root mean square displacement (RMSD). The results show that for Ag nanoparticles with diameter less than…
It is shown that angular stiffness in the hexagonal lattice model plays a significant role in the geometrical nonlinear terms in the equations of the continuum limit. A geometrically nonlinear discrete model is formulated for the hexagonal lattice by considering the interaction of two sublattices. An asymptotic proced…

Abstract The widespread growth of additive manufacturing, a field with a complex informatic “digital thread”, has helped fuel the creation of design repositories, where multiple users can upload distribute, and download a variety of candidate designs for a variety of situations. Additionally, advancements in additive…
