Using field effect devices with side gates, we modulate the 2-dimensional electron gas hosted at the ${\mathrm{LaAlO}}_{3}/{\mathrm{SrTiO}}_{3}$ interface to study the temperature and doping evolution of the magnetotransport. The analysis of the data reveals different transport regimes depending on the interplay betwe…
Abstract Since the discovery of metal chalcogenide complexes (MCCs) as capping ligands for colloidal nanocrystals (NCs) in 2009, the chemistry of inorganic ligands for NCs has provided a new paradigm for surface design of nanomaterials. Various inorganic anions including MCCs, metal-free chalcogenides, oxoanions/oxome…
Various metal hydroxides/oxides grown on conductive substrates such as nickel foam have been reported and studied as supercapacitor electrode materials. However, the capacitances of these electrodes are extremely limited because of the low content of active materials grown on the limited surface of nickel foam. To ach…
Impedance spectroscopy (IS) is used to compare defects and charge transport in (001) oriented K 0.5 Na 0.5 NbO 3 (KNN) single crystals and its polycrystalline counterpart. KNN single crystals show lower conductivity than polycrystalline counterpart from room temperature up to 200 °C, but above this temperature polycry…
An as-cast Ni-Al bronze (NAB) was subjected to friction-stir processing (FSP). The friction-stir processed NAB (FSPed NAB) exhibited better corrosion resistance in a 3.5 wt% sodium chloride solution. The corrosion product films formed on the as-cast and FSPed NAB were characterized by scanning electron microscopy (SEM…
Polylactide (PLA) is one of the most mature biobased and biocompostable plastics currently in the market. Despite its mechanical properties comparable to the ones of some mainstream petroleum-based thermoplastics (PS, for instance), PLA inherent brittleness and heat sensitivity are issues for its full industrial devel…
High Resolution Image Download MS PowerPoint Slide The oxidation and reduction of CuZn nanoparticles was studied using X-ray photoelectron spectroscopy (XPS) and in situ transmission electron microscopy (TEM). CuZn nanoparticles with a narrow size distribution were produced with a gas-aggregation cluster source in con…
Controversial reports regarding Stöber silica's microporosity and specific surface area remain in the literature despite decades of widespread applications. In this work, Stöber silica samples prepared under controlled reaction time and postsynthesis washing/drying conditions were characterized by nitrogen adsorption…
In this work, a two-step chemical-potential-gradient model based on nonequilibrium thermodynamic principles was developed to investigate the dissolution mechanism of crystalline active pharmaceutical ingredients (APIs). The perturbed-chain statistical associating fluid theory was used to calculate the required solubil…
We investigate the response of passive lossless Huygens metasurfaces (HMS), designed to implement a prescribed refraction, to arbitrary plane-wave excitations. Applying a rigorous Floquet-Bloch (FB) analysis of the cotangent electric and magnetic surface reactance modulations, we discover that the scattered FB modes f…
A new one-step method for the preparation of graphene oxide (GO) nanostructures has been developed by pulsed laser ablation in GO solution. The formation of different shapes of GO nanostructures, such as ribbons, nanoflakes (including nano-squares, nano-rectangles, nano-triangles, nano-hexagons, and nano-disks) and qu…
Stabilized fullerene and tubular forms can be produced in boron clusters Bn in small sizes from n∼ 14 to 20 upon doping by transition metal atoms. B14Fe and B16Fe are stable tubes whereas B18Fe and B20Fe are stable fullerenes. Their formation and stability suggest the use of dopants to induce different growth paths le…
We investigated the AC conductivity in 60V2O5–(40 − x)P2O5–xB2O3 (x = 5, 10, 20, 30 and 35 mol%) glasses as a function of temperature. The measurements were carried out in the frequency range from 20 Hz to 1 MHz with varying temperatures (303–473 K). The samples were characterized by using X-ray diffraction (XRD) and…
We report giant temperature dependent negative magnetization (magnetization reversal) along with a large exchange bias and large coercivity in SmCrO3. The static magnetization measurements show the negative magnetization below ~192 K, due to competition between the external field, thermal activation energy and antipar…
High internal phase emulsion (HIPE) xerogels based on charge-driven assembled polymer HIPE organogels were prepared by freeze-drying and examined as oil absorbents for oil spill recovery.
A needleless electrospinning setup named 'Needleless Twisted Wire Electrospinning' was developed. The polymer solution is electrospun from the surface of a twisted wire set to a high voltage and collected on a cylindrical collector around the wire. Multiple Taylor cones are simultaneously self-formed on the downward f…
Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they are likely to come in contact with microbial communities like periphyton, which plays a key role as a primary producer in stream ecosystems. At present, however, very little i…
Sandwich-type N-doped graphene based carbon materials with a wrinkled sheet-like morphology were prepared, and they demonstrated remarkable performances as supercapacitor electrodes.
Molecular dynamics simulations have been investigated to study the interactions between single-wall carbon nanotubes and an anticancer agent Pt complex (Cisplatin). The optimized diameter of the vector system has been determined to encapsulate in the best conditions the drug molecules. The simulation results show also…
Achieving 180° magnetization reversal with an electric field rather than a current or magnetic field is a fundamental challenge and represents a technological breakthrough towards new memory cell designs. Here we propose a mesoscale morphological engineering approach to accomplishing full 180° magnetization reversals…
