Linear low‐density polyethylene (LLDPE)‐based composites were prepared through melt compounding and hot pressing using both untreated and treated halloysite nanotubes (HNT) up to filler contents of 8 wt% to assess the role of the filler exfoliation and surface treatment on the thermal, mechanical, and rheological prop…
Abstract The enzymeless glucose oxidation process readily occurs on nano‐gold electrocatalyst at pH 7, but it is highly susceptible to poisoning (competitive binding), for example from protein or chloride. Is it shown here that gold nanoparticle catalyst can be protected against poisoning by a polymer of intrinsic mic…
We present the design, fabrication, and characterization of guided-mode resonance (GMR) linear polarizers that operate in the optical communications C-band near a wavelength of 1550 nm. We provide theoretical and experimental spectra using resonant elements fashioned in three material systems. In particular, we invest…
The purpose of this work is to determine the chemical composition of the previously reported faradaurates, which is a large 76.3 kDa thiolated gold nanomolecule. Electrospray ionization quadrupole-time-of-flight (ESI Q-TOF) mass spectrometry of the title compound using three different thiols yield the 329:84 gold to t…
Titanium dioxide (TiO2) nanoparticles (NPs) are commonly used materials present in many consumables for which most people are exposed to. The biological hazards of the NPs on human health have been demonstrated previously. In this study, we aimed to assess the cytotoxicity potency of TiO2 NPs on the primary human amni…
Inspired by recent successful synthesis of room-temperature ferroelectric supramolecular charge-transfer complexes, i.e., tetrathiafulvalene (TTF)- and pyromellitic diimide (PMDI)-based crystals (Tayi et al. Nature 2012, 488, 485-489), three new ferroelectric two-component organic molecular crystals are designed based…
Various stacking patterns have been predicted in few-layer MoS 2, strongly influencing its electronic properties. Bilayer MoS 2 nanosheets have been synthesized by vapor phase growth. It is found that both A-B and A-A′ stacking configurations are present in bilayer MoS 2 nanosheets through optical images, and the diff…
Sensing is to date one of the most successful applications of surface plasmons thanks to the exceptional field amplification and sensitivity of these modes in metallic nanostructures. Here we introduce a promising detection scheme based on the propagation of strongly confined antibonding plasmons supported by graphene…
For many applications of the nitrogen-vacancy (NV) center in diamond, the understanding and active control of its charge state is highly desired. In this work, we demonstrate the reversible manipulation of the charge state of a single NV center from NV(-) across NV(0) to a nonfluorescent, dark state by using an all-di…
Using a novel two-step fabrication scheme, we create highly semiconducting-enriched single-walled carbon nanotube (sSWNT) bulk heterojunctions (BHJs) by first creating highly porous interconnected sSWNT aerogels (sSWNT-AEROs), followed by back-filling the pores with [6,6]-phenyl-C(71)-butyric acid methyl ester (PC(71)…
We present a miniature collector for the adsorption and collection of oil spill. The collector composed of a superhydrophobic copper mesh miniature box embedded with a superoelophilic polyurethane sponge. The superhydrophobic Cu mesh was fabricated by a simple immersing method, and the PU sponge is a commercial availa…
Numerous recent investigations have been devoted to the determination of the equilibrium phase behavior and packing characteristics of hard nonspherical particles, including ellipsoids, superballs, and polyhedra, to name but just a few shapes. Systems of hard nonspherical particles exhibit a variety of stable phases w…
The formation, growth, and phase transition of colloidal monodisperse spherical copper sulfide nanocrystals synthesized in dodecanethiol have been followed by in situ synchrotron powder X-ray diffraction (PXRD). The formation of nanocrystals involves a thermal decomposition of the crystalline precursor [CuSC12H25], wh…
A new technique, electro-hydrodynamic nanowire (e-NW) lithography , is demonstrated for the rapid, inexpensive, and efficient fabrication of graphene nanorib bons (GNRs) on a large scale while simultaneously controlling the location and alignment of the GNRs. A series of interesting GNR architectures, including parall…
Atomistic molecular dynamics simulations are performed on oligomeric polyamide-6,6 chains, composed of 10 chemical repeat units, at a carbon nanotube (CNT) interface. The effect of surface curvature on the structure and dynamics of polymer is studied by simulating systems containing CNTs of various diameters. It is sh…
The oxidation of CO is the archetypal heterogeneous catalytic reaction and plays a central role in the advancement of fundamental studies, the control of automobile emissions, and industrial oxidation reactions. Copper-based catalysts were the first catalysts that were reported to enable the oxidation of CO at room te…
A trinuclear complex [(CuL) 2 Tb(H 2 O)(NO 3 ) 3 ]·MeOH·H 2 O ( 1 ) is synthesized by using a metalloligand [CuL] (H 2 L = N, N ′-bis(salicylidene)-1,3-propanediamine or salpn). This complex is used as a new 3d-4f metallatecton for stepwise supramolecular oligomerization along with a simple diimine linker, 4,4′-bipyri…
Adsorptive removal of cationic brilliant green (BG) dye by dodecyl-benzene-sulfonic-acid doped polyaniline/multiwalled carbon nanotubes composite has been investigated as a function of contact time, solution pH, initial dye concentration, and temperature. Raman spectroscopy, Fourier transforms infrared spectroscopy, s…
Graphene is a wonder material with the ultimate smallest thickness that is readily accessible to various approaches for engineering its excellent properties. Graphene doping is an efficient way to tailor its electric properties and expand its applications. This topic covers wide research fields and has been developing…
A weak aspect of the in vitro studies devoted to get information on the toxic, genotoxic and carcinogenic properties of nanomaterials is that they are usually conducted under acute-exposure and high-dose conditions. This makes difficult to extrapolate the results to human beings. To overcome this point, we have evalua…
