The composition/structure−function relationship is the underlying motive for discovering and designing novel nanomaterials with distinct properties and for special applications. In this paper, we for the first time investigated the structure and composition related properties of inorganic coordination complexes of nic…
The linewidth of the resonances in the single-electron tunneling spectra has been investigated for PbSe semiconductor nanocrystals (NCs) with scanning tunneling spectroscopy at low temperature. The linewidth of the resonances corresponding to tunneling through the first conduction and valence levels is found to increa…
Experimental methods for preparing long linear atomic chains from graphene and for using the chains to connect nanodevices are proposed based on classical and first-principles molecular dynamics simulations. We show that these methods are promising to pull out long monatomic chains, to dope other atoms, such as boron,…
Pyroshock can cause malfunctions of electric components of launch vehicles or satellites, resulting in a catastrophic flight failure. This study introduces a new compressed mesh washer pyroshock isolator using the pseudoelasticity of Ni-Ti alloy wire. The compressed mesh washer isolators were manufactured and tested t…
Abstract In this study, cationic surfactants having different alkyl chain lengths were prepared by amidation of lauric, myristic, palmitic, stearic, oleic acids with diethylene triamine. The products were quaternized using chloroacetic acid. The chemical structure of the prepared compounds was elucidated using differe…
Two novel octadentate ligands have been synthesized by attaching two terminal iminodiacetic groups to either 1,4-diazepane (BCAED) or piperazine (BCAEP) as central scaffold. The introduction of the seven- or six-membered ring into the ligand backbone is expected to modify their overall flexibility and then to affect t…
On the basis of combining the effect of digestive ripening and seeding growth, a generalized route for precisely controlling the size of noble monodisperse (MD) nanoparticles (NPs), the shell thickness of core−shell NPs, and composition of alloy NPs has been reported. First, small NPs are dispersed in high-boiling-poi…
The change in the local order of amorphous sputter deposited GeTe thin films irradiated with ${\text{Ge}}^{+}$ ion and its influence on the subsequent thermal induced crystallization has been investigated by means of micro-Raman spectroscopy and in situ time-resolved reflectivity. A reduction in the Ge-rich tetrahedra…
Gold nanoparticle arrays created with electroless gold plating provide a unique means of transforming nanocylinders usually formed in electron beam lithography to spherical nanoparticles. Alone, electroless gold plating is not selective to the substrate and results in the formation of a gold film on all exposed surfac…
Simultaneously enhanced reflectance and transmittance greater than 35 dB are demonstrated for the lasing spaser (or spasing) behavior in an active fishnet metamaterial. In mimicking a lasing cavity, an equivalent active slab with Lorentz dispersion for the index of refraction is established to model the spasing metama…
A supramolecular hybrid is prepared by the supramolecular surface modification of single-walled carbon nanotube (SWCNT) with cationic beta-cyclodextrin-tethered ruthenium complexes through a spacer molecule that contains both an adamantane and a pyrene moiety. By employing the supramolecular hybrid, spatially controll…
A copolyacrylate with semifluorinated and polydimethylsiloxane side chains (D5-3) was used as a surface modifier for a condensation-cured PDMS coating. The decyl fluorous group is represented by "D"; "5" is a 5 kDa silicone, and "3" is the mole ratio of fluorous to silicone side chains. Wetting behavior was assessed b…
We report here a unique, simple method for synthesizing polymer film gradients with nanometer thickness through diffusion controlled surface polymerization. Polar solvents, especially water, have previously been shown to increase the rate of atom transfer radical polymerization (ATRP) of numerous monomers. That result…
A UV absorber, 5,5′-methylenedisalicylic acid (MDSA), has been intercalated into a ZnAl−NO 3 layered double hydroxide (LDH) by an ion-exchange method. After intercalation of MDSA, the basal spacing in the LDH increased from 0.90 to 1.53 nm, suggesting that the MDSA anions were arranged in the interlayer galleries of Z…
Abstract Highly filled wood/poly(vinyl chloride) (WPVC) composites were manufactured in five different cross sections by using an industrial‐scale twin‐screw extruder. The flexural properties of such composites were evaluated, with the effects of sample direction, span length, and rate of loading also being taken into…
Naproxen was loaded in poly-caprolactone (PCL) nanoparticles as an implantable sustained release system to prolong its anti-inflammatory activity. Naproxen-loaded nanoparticles were produced with the following characteristics: Nanometric size (< 300 nm), negative zeta potential, low polydispersity index (< 0.1), satis…
The imaging properties of a phase conjugating lens operating in the far field zone of the imaged source and augmented with scatterers positioned in the source near field region are theoretically studied in this paper. The phase conjugating lens consists of a double sided 2D assembly of straight wire elements, individu…
Nanopharmacoeuticals based on nanomaterials and nanotechnology are medicinal products for drug delivery, nano drugs and nano therapies, in vivo imaging, in vitro diagnostics, biomaterials, and active implants. Nanoscience and nanotechnology in China become ever more consequential in our lives; all members of the scien…
It has been recognized that the cross-magnetizing phenomenon of saturated synchronous machines plays an important role in their analysis using the two-axis frame models. In this paper, the finite-element method (FEM) is applied to determine from 2-D static electromagnetic field solutions the parameters representing th…
Creating autologous tissues with on-demand and native-like biomechanical properties is the ultimate challenge in functional heart valve tissue engineering. A promising approach toward this goal is to induce development of native-like tissue structure in vitro by mimicking the diastolic loading phase in a bioreactor. H…
