The magnetic properties of anatase Ti1?xMnxO2 (0 < x < 0.06) films prepared by sol?gel spin coating annealed in air and vacuum have been investigated. Room temperature ferromagnetism was observed in all the films. Enhancement of ferromagnetism is revealed in the films annealed in vacuum. The magnetic moment of the fil…
In order to test for the true intrinsic properties of icosahedral $i\text{\ensuremath{-}}\mathrm{Al}\text{\ensuremath{-}}\mathrm{Cu}\text{\ensuremath{-}}\mathrm{Fe}$ quasicrystals, we performed investigations of magnetism, electrical resistivity, thermoelectric power, and thermal conductivity on a single-crystalline $…
In this paper we present the mechanical and microstructural characterization results of through-wafer electroplated copper interconnects. Copper was deposited in very high aspect ratio (∼15), narrow (15 µm) through-vias in silicon, which were earlier created by deep reactive ion etching. The two critical mechanical pr…
We write this article in honor of Professor Vitaly L. Ginzburg, truly the father of the field of ferroelectricity. This article serves as a review of the current state of research pertaining to multiferroic BiFeO 3 thin films. In this review we will delve into details of the growth of BiFeO 3 thin films and the use of…
Abstract Amino acid family crystals exhibit excellent nonlinear and electro‐optical properties. L‐alanine alaninium nitrate (LAAN) single crystal belonging to the amino acid group was grown by slow cooling solution growth technique. The High resolution X‐ray diffraction (HRXRD), Fourier transform infrared (FTIR) spect…
Branched and sub-branched SnO(2) hierarchical architectures in which numerous aligned nanowires grew on the surface of nanobelt substrates have been obtained by a multistep thermal vapor deposition route. Branch size and morphology can be controlled by adjusting the temperature and duration of growth. The same approac…
Water-soluble carbon-nanohorn-tetrathiafulvalene (CNH-TTF) nanoensembles were prepared by utilizing positively charged pyrene as an assembly medium and characterized by spectroscopy and electron microscopy. Electronic interactions within the nanoensemble were probed by optical spectroscopy, indicating electron transfe…
Abstract The tensile properties and fracture surfaces of N ‐methylmorpholine‐ N ‐oxide (NMMO) regenerated silk fibroin fibers produced with a range of draw ratios has been characterized and related to their microstructure with data obtained from Raman spectroscopy and birefringence measurements. The spinning process a…
A solid-state dynamic supramolecular structure consisting of (anilinium)([18]crown-6) was arranged as the cation in a salt of [Ni(dmit)2]- (dmit = 2-thioxo-1,3-dithiole-4,5-dithiolate). With the ammonium moiety of anilinium located within the cavity of [18]crown-6, a hydrogen-bonded supramolecular structure is formed,…
Gradient pore structure TiO 2 sheets were fabricated by a novel freeze–tape‐casting process. Aqueous TiO 2 ceramic slurries were prepared by the traditional tape‐casting processing and were then cast onto an aluminum foil carrier. The slurries were immediately frozen on the substrate, whose temperature was about −18°C…
There are several reports on the synthesis of fuel additives based on oleochemical esters, and physical data on some of these compounds is lacking. Herein, we report the surface tension of several epoxidized oleochemicals and their comparable fatty esters, at temperatures between 25 and 60 °C. Surface tensions of the…
Abstract The reinforcement and nonlinear viscoelastic behavior have been investigated for silica (SiO 2 ) filled solution‐polymerized styrene butadiene rubber (SSBR). Experimental results reveal that the nonlinear viscoelastic behavior of the filled rubber is similar to that of unfilled SSBR, which is inconsistent wit…
Highly crystalline CaMoO 4:Tb 3+ phosphor layers were grown on monodisperse SiO 2 particles through a simple sol−gel method, resulting in formation of core−shell structured SiO 2 @CaMoO 4:Tb 3+ submicrospheres. The resulting SiO 2 @CaMoO 4:Tb 3+ core−shell particles were fully characterized by powder X-ray diffraction…
Abstract Nanoplates, flower‐like nanostructure of ZnO were successfully synthesized by employing ZnSO 4 ·7H 2 O, NaOH as the starting materials at 120°C under hydrothermal condition. Keeping the same parameters, ZnO urchin shape was obtained by addition of vitamin C at 190°C. Characterizations were carried out by X‐ra…
Highly monodisperse submicrometer CdS colloidal spheres (CSCS) with a controllable and tunable size (between 80 and 500 nm) have been synthesized through a facile solvothermal technique. Owing to the controllability of the reaction process, the growth mechanism of the colloidal spheres has been elucidated in detail. T…
Abstract BACKGROUND: The physical properties of polyamides can be enhanced through incorporation of inorganic micro‐ and nanofillers such as silica nanoparticles. Transparent sol‐gel‐derived organic‐inorganic nanocomposites were successfully prepared by in situ incorporation of a silica network into poly(trimethylhexa…

We study the changes in the low-frequency vibrational dynamics of poly(isobutylene) under pressure up to 1.4 GPa, corresponding to a density change of 20%. Combining inelastic neutron, x-ray, and Brillouin light scattering, we analyze the variations in the boson peak, transverse and longitudinal sound velocities, and…
Abstract There is a need for highly sensitive, multi‐parallel protein sensors within diagnostics and proteomic research. Conjugated polymers (CPs) have been demonstrated as highly sensitive optical probes for protein biosensing. Compared to small molecules, the polymeric probe has the possibility of multiple interacti…
We present a robust and straightforward approach for fabricating a novel colloidosome system where colloidal particles are assembled to form colloidal shells on the surface of stimuli-responsive microgel scaffolds. We demonstrate that the structural properties of the colloidal shells can be controlled through the coll…
