Superhydrophobic surfaces are attractive because of their special wettability properties. In recent years, artificial superhydrophobic surfaces have been studied extensively because of the demand for self-cleaning materials.1-6 The contact angle of water on a clean surface is a measure of its hydrophobicity. A water c…
This paper reports our works on the preparation of the silver-nanoparticle-incorporated ultrafine polyimide (PI) ultrafine fibers via a direct ion exchange self-metallization technique using silver ammonia complex cation ([Ag(NH(3))(2)](+)) as the silver precursor and pyromellitic dianhydride (PMDA)/4,4'-oxidianiline…
The Bcl-2 family of proteins includes the major regulators and effectors of the intrinsic apoptosis pathway. Cancers are frequently formed when activation of the apoptosis mechanism is compromised either by misregulated expression of prosurvival family members or, more frequently, by damage to the regulatory pathways…
We studied various Heusler alloy compositions for the ferromagnetic layers of current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) spin-valves (SVs) to obtain large MR outputs for the read sensor applications. The exchange biased SV with Co2Fe(Al0.5Si0.5) alloy showed a resistance change-area product (ΔRA)…
This study successfully isolates a fraction of intra-crystalline proteins from shells of the marine gastropod Patella vulgata and assesses the suitability of these proteins for IcPD (Intra-crystalline Protein Diagenesis) geochronology. We discuss the mineralogical composition of this gastropod, investigated for the fi…
The electronic structure and optical properties of very recently synthesized chevron-type graphene nanoribbon (CGNR) are investigated within many-body Green’s function and Bethe–Salpeter equation formalism. The CGNR can effectively confine both electrons and holes, leading to its exciton binding energy larger than tha…
Building functional cages: The first lanthanide-containing organodiphosphonate-functionalized polyoxomolybdate cages have been prepared. They exhibit interesting photocatalytic properties in the decomposition of organic dyes (see figure).
Adsorption of phenanthrene on carbon nanotubes (CNTs) was examined in the presence of pulmonary surfactant (Curosurf) and its main components, dipalmitoyl phosphatidylcholine (DPPC) and bovine serum albumin (BSA). A passive-dosing method based on equilibrium partitioning from a preloaded polymer was successfully emplo…
In this work, the feasibility of producing microcellular foam by using homopolymer linear polypropylene with an melt flow index of 18 g/10 min, a high melt flow index coupling agent (G3003, melt flow index of 380 g/min), and different nanoclay (Cloisite 20A) content was investigated. A twin-screw extruder was used to…
The nanoscale protrusions of different morphologies on wing surfaces of four cicada species were examined under an environmental scanning electron microscope (ESEM). The water contact angles (CAs) of the wing surfaces were measured along with droplet adhesion values using a high-sensitivity microelectromechanical bala…
Gold nanoparticles (AuNPs) with core sizes below 2 nm and compact ligand shells constitute versatile platforms for the development of novel reagents in nanomedicine. Due to their ultrasmall size, these AuNPs are especially attractive in applications requiring delivery to crowded intracellular spaces in the cytosol and…
INTRODUCTION: Many amphiphilic copolymers have recently been synthesized as novel promising micellar carriers for the delivery of poorly water-soluble anticancer drugs. Studies on the formulation and oral delivery of such micelles have demonstrated their efficacy in enhancing drug uptake and absorption, and exhibit pr…
Abstract Biosynthesis of silver nanoparticles (NPs) using D. carota extract was investigated for various concentrations of D. carota extract. The aqueous silver ions were reduced into silver NPs when they interacted with D. carota extract. The silver NPs were characterized by UV-visible spectroscopy, Fourier transform…
A new β-diketone, 2-(2,2,2-trifluoroethyl)-1-indone (TFI), which contains a trifluorinated alkyl group and a rigid indone group, has been designed and employed for the synthesis of two series of new TFI lanthanide complexes with a general formula [Ln(TFI)(3)L] [Ln = Eu, L = (H(2)O)(2) (1), bpy (2), and phen (3); Ln =…
The Wool ComfortMeter provides an objective measurement of the fabric-evoked prickle discomfort rating provided by wearers. This work aimed to quantify the sensitivity of the Wool ComfortMeter over a range of different temperature and humidity conditions to determine the recommended test conditions for its operation.…
We analyze the appropriate form for the generalized Stokes-Einstein relation (GSER) for viscoelastic solids and fluids when bead inertia and medium inertia are taken into account, which we call the inertial GSER. It was previously shown for Maxwell fluids that the Basset (or Boussinesq) force arising from medium inert…
An efficient and controllable approach to prepare cross-linked films from a conjugated polymer precursor by electrochemical deposition (ED) is reported for the first time. A novel polymer precursor with high solubility, high electroactivity, and electron-transport ability has been designed. The electrochemically depos…
This study investigates the effect of temperature on CdSe/ZnS quantum dots (QDs) in GaN-based light-emitting diodes (LEDs) using the phosphor conversion efficiency (PCE) and LED junction temperature. In our simulation, the blue chip and CdSe/ZnS QDs temperature are similar because of their minimal thickness. Furthermo…
The first 3d-4f-5d heterotrimetallic complexes using [W(V)(bipy)(CN)(6)](-) as a metalloligand were synthesized (bipy = 2,2'-bipyridine). The structural and magnetic properties of three [Cu(II)Ln(III)W(V)] complexes (Ln = Gd, Ho, Tb) are discussed.
Inelastic neutron scattering is employed to study the reciprocal-space structure and dispersion of magnetic excitations in the normal and superconducting states of single-crystalline Rb${}_{0.8}$Fe${}_{1.6}$Se${}_{2}$. We show that the recently discovered magnetic resonant mode in this compound has a quasi-two-dimensi…
