Abstract UNS S17400 steel is used in turbines for the aerospace and utility industries. While it is generally corrosion resistant, it is susceptible to pitting when exposed to aqueous chloride environments. Effects of pitting characteristics, such as depth, width, and local density on fatigue life, have been studied i…
In this study, electrochemical measurements, immersion tests, and slow strain rate tensile (SSRT) tests were applied to investigate the electrochemical and stress corrosion cracking (SCC) behavior of X70 steel in simulated seawater with the interference of different alternating current (AC) densities. The results indi…
Cubic boron arsenide (c-BAs) has been predicted to exhibit thermal conductivity values around 1400 W/m-K at room temperature by first-principles calculations and, thus, shows promise to be one of the solutions for the thermal management challenge faced by the semiconductor industry. However, the size of single crystal…
Strong in-plane anisotropy of atomic layer and thin-film black phosphorus (P) offers new device perspectives and stimulates increasing interest and explorations, where precisely determining the black P crystal orientation and anisotropic axes is a necessity. Here, we demonstrate that the crystal orientation and intrin…
Various phase diagrams of charge density wave (CDW) and superconductivity (SC) have been reported in layered transition-metal dichalcogenides. Some of the ordered phases in these diagrams are not universal because they rely on different critical factors, leading to the proliferation of contradictory arguments about CD…
Amphiphilic cyclodextrins (aCDs) are an intriguing class of carrier systems which, recently, have been proposed to deliver porphyrinoids and anticancer drugs or combined dose of both for dual therapeutic applications. The design of nanoassemblies based on aCD and photosensitizers (PSs) aims to preserve the photodynami…
Jute fabric samples were treated, with different formulations, using various proportions of bitumen emulsion and polyester (PE) resin in combined solutions. Styrene monomer was used as solvent, methyl ethyl ketone peroxide as cross-linking agent and cobalt naphtha as curing agent. The fabric specimens were immersed in…
A new class of mixed-charged zwitterionic copolymer poly(aminoethyl methacrylate)- co-poly(methacrylic acid)- co-poly( n-butyl methacrylate) (CPMA) was prepared as drug nanocarrier for efficient intracellular delivery of Doxorubicin (DOX). The mixed-charged CPMA copolymer could readily assemble to micelles in physiolo…
Effects of B site ions on the relaxor to normal ferroelectric crossover in Ba4Sm2Zr4(NbxTa1-x)6O30 (x = 0, 0.3, 0.5, 0.7, 0.9, and 1) tungsten bronze ceramics were investigated. The tetragonal tungsten bronze structure in space group P4/mbm was confirmed for compositions of x = 0, 0.3, and 0.5, while space group P4bm…
Abstract Harnessing the unique polarized light emission characteristic from semiconductor quantum rods (QRs) necessitates their large‐area unidirectional alignment. Herein, the aligned assembly of CdSe/CdS QRs is demonstrated by fabricating a functional film on a micrometer‐spaced interdigitated electrodes substrate o…
High Resolution Image Download MS PowerPoint Slide Silicone-containing biobased hyperbranched polyurethane thermoplastic elastomers at different compositions were reported for the first time. The structures of the polymers were evaluated from Fourier transform infrared spectroscopy, NMR, X-ray diffraction, and energy-…
Abstract A tripeptide containing an oligo‐methylene group was found to form hydrogels at the two pH extremes (in presence of an acid or a base); however, it does not form a hydrogel at neutral pH. We use this property to obtain a hydrogel of the peptide in the presence of an organic acid, citric acid. The redox potent…
It is known that specific oligomers of single-stranded DNA (ssDNA) can show remarkable selectivity when coating different structural species of single-wall carbon nanotubes (SWCNTs). We report that (ATT) 4 ssDNA coatings strongly distinguish between the two optical isomers of (7,5) SWCNTs. This causes resolvable shift…
In this study, we explore for the first time the capabilities of nanoporous anodic alumina gradient-index filters (NAA-GIFs) functionalized with titanium dioxide (TiO 2 ) photoactive layers to enhance photon-to-electron conversion rates and improve the efficiency of photocatalytic reactions by “slow photon” effect. A…
Abstract Despite the rapid rise in diversity and quantities of engineered nanomaterials produced, the impacts of these emerging contaminants on the structure and function of ecosystems have received little attention from ecologists. Moreover, little is known about how manufactured nanomaterials may interact with nutri…
Cationic polylysine promotes, under neutral conditions, the spontaneous aggregation of opposite charged ZnTPPS in water. Spectroscopic investigations evidence a different preorganization of ZnTPPS onto the polypeptide matrix depending on the chain length. Spinodal decomposition theory in confined geometry is used to m…
Abstract 2D van der Waals materials are promising for various electronic and optoelectronic devices because of their thickness‐dependent mobility and tunable bandgap. Recently, heterojunction structures based on 2D van der Waals materials have exhibited their potential for photovoltaic applications as ultrathin p–n di…
High Resolution Image Download MS PowerPoint Slide Polymers or small molecules with functional groups were always employed to synthesize two-dimensional (2D) silver nanostructures, but the polysaccharides and derivatives have rarely been used for their preparation, let alone of uniform quadrilateral shapes. Herein, am…
Abstract Magnetoelectric (ME) composite materials have a stronger ME coupling effect in resonant states than in non-resonant states. Typically, these resonant states appear at frequencies of several tens of kHz or even MHz. However, for DC and low-frequency applications of ME composites, obtaining a high ME response i…
The recently emerging laminar transition metal dichalcogenides provide an unprecedented platform for exploring fascinating layer-dependent properties. Determining the dependence of exciton-phonon coupling (EPC) on dimensionality would set a foundation for these exotic thickness-dependent phenomena. Here we report the…
