Droplet epitaxy is a flexible nanomaterial growth technique and is a potential method to fabricate advanced electronic and optoelectronic devices. Here, we report strain-free GaAs/Al0.33Ga0.67As quantum ring solar cells fabricated by droplet epitaxy technique. Photoluminescence is used to study the electronic structur…
Density functional theory (DFT) calculations are performed to investigate the effect of functionalized linkers on CO 2 binding in zeolitic imidazolate frameworks (ZIFs). Three typical ZIFs with different functionalized linkers are considered: ZIF-68 with bIM linker (C 6 H 6 group), ZIF-69 with cbIM linker (chlorine gr…
Silicon nanowires (SiNW) were formed on large grained, electron-beam crystallized silicon (Si) thin films of only ∼6 μm thickness on glass using nanosphere lithography (NSL) in combination with reactive ion etching (RIE). Electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) studies reveal…
Complex plasmas and colloidal dispersions represent different states of soft matter. They are complementary in many ways, with the most important being that complex plasmas are virtually undamped at the particle timescales, whereas colloidal dispersions are overdamped and therefore can be brought into equilibrium in a…
In this work, a GO/aptamer system was constructed to create multiplex logic operations and enable sensing of multiplex targets. 6-Carboxyfluorescein (FAM)-labeled adenosine triphosphate binding aptamer (ABA) and FAM-labeled thrombin binding aptamer (TBA) were first adsorbed onto graphene oxide (GO) to form a GO/aptame…

The present paper describes the successful one-pot synthesis of self-stabilized particles composed of amphiphilic block copolymers based on poly(methacrylic acid) (PMAA) obtained by polymerization-induced self-assembly. First, controlled radical polymerization of MAA is performed in water using the RAFT process by tak…
Over the past three decades, revolutionary research in nanotechnology by the scientific, medical, and engineering communities has yielded a treasure trove of discoveries with diverse applications that promise to benefit humanity. With their unique electronic and mechanical properties, carbon nanomaterials (CNMs) repre…
A mixed ionic–electronic conductor (MIEC) of polypyrrole (PPy) synthesized with poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAAMPSA), which is water-dispersible and is in the form of nanoparticles intertwined by the PAAMPSA, is explored as an additive in sulfur cathodes for rechargeable lithium–sulfur (Li–S) b…
Three enzymes, triosephosphate isomerase (orange in picture), aldolase (cyan), and fructose 1,6-bisphosphatase (purple), which contained dockerins (red), self-assembled into a static trifunctional enzyme complex through interaction with a mini-scaffoldin protein consisting of three different cohesins (green). The synt…
OBJECTIVE: The purpose of this review is to describe trends in microbubble application in molecular imaging. CONCLUSION: Microbubbles are used for contrast ultrasound imaging as blood-pool agents in cardiology and radiology. Their promise as targeted agents for molecular imaging is now being recognized. Microbubbles c…
Anatase TiO2 sheets with exposed high-energy (001) facets are grown on carbon fibers (CFs) by a facile hydrothermal synthetic route. The percentage of reactive facets in the TiO2 nanosheets (NSs) is calculated to vary between about 40% and 92%, depending on the synthesis conditions. In comparison with TiO2 NSs grown o…
Abstract Recently, a large number of experimental and theoretical works have revealed a variety of plasmonic nanostructures with the capabilities of Fano resonance (FR) generation. Among these structures, plasmonic oligomers consisting of packed metallic nanoelements with certain configurations have been of significan…
A simple method for preparing 5-fluorouracil surface-functionalized selenium nanoparticles (5FU-SeNPs) with enhanced anticancer activity has been demonstrated in the present study. Spherical SeNPs were capped with 5FU through formation of Se-O and Se-N bonds and physical adsorption, leading to the stable structure of…
BACKGROUND: Today, recognition and classification of sequence motifs and protein folds is a mature field, thanks to the availability of numerous comprehensive and easy to use software packages and web-based services. Recognition of structural motifs, by comparison, is less well developed and much less frequently used,…
We report on homodyne dynamic light scattering measurements of orientational fluctuation modes in both calamitic and bent-core nematic liquid crystals, carried out in the new split-helix resistive magnet at the National High Magnetic Field Laboratory. The relaxation rate and inverse scattered intensity of director flu…
In the present paper, the possibility of using thermoelectric power generator modules (TEGs) to convert the heat generated by the photovoltaic/thermal (PVT) collector into electricity is investigated. A comprehensive heat transfer model for the combined PVT-TEG system is developed via MATLAB and simulated under differ…
Undoped, Cu-doped, Se-enriched, and Cu2Se-doped ZnSe films have been grown on fused quartz substrates by pulsed laser deposition. While the other films are highly resistive, Cu2Se-doped ZnSe films are p-type conducting with hole concentrations of ∼1.1 × 1019 cm−3 and resistivities of ∼0.098 Ω cm (compared with previou…
We demonstrate sub-wavelength grating couplers patterned on glass surfaces which are designed to convert incident free-space radiation into guided modes along the glass material. The devices are fabricated by nanoimprint lithography and the measured optical performance is compared to a simple model based on diffractio…
We propose a study of a generalized Airy-like formula of the transmittance through planar resonators. A complete and analytical analysis of total transmission conditions is given according to physical parameters. The homogeneous problem related to free oscillations of resonators, which leads to complex resonance frequ…
