Extinction, scattering, and absorption cross sections and efficiencies were experimentally measured for chemically clean silver nanoparticles in water for 16 different sizes ranging from 29 to 136 nm. The measured efficiencies indicate that particles interact with light 4-10 times stronger than the geometric cross sec…
Multiwalled carbon nanotubes (MWNTs)/nylon-6 (PA6) nanocomposites with different MWNTs loadings have been prepared by the simple melt-compounding approach. A fine and homogeneous dispersion of MWNTs throughout PA6 matrix is observed by transmission electron microscopy. Scanning electron microscopy observation on the f…
Polylactide polymers have gained enormous attention as a replacement for conventional synthetic packaging materials in the last decade. By being truly biodegradable, derived from renewable resources and by providing consumers with extra end-use benefits such as avoiding paying the "green tax" in Germany or meeting env…
Abstract Magnetostriction was measured in 3% Si‐Fe grain‐oriented electrical steel under a nonuniform temperature distribution with a 5 to 10 °C difference in a single sheet measuring 100 × 500 mm. A temperature difference of 0.2 °C/mm in the sheet increased magnetostriction four times as much as in the case of a unif…

In this article we describe a field study of biofouling and microbiologically influenced corrosion (MIC) of admiralty brass heat exchanger tubes in contact with running fresh water on the river Tagus close to Almaraz nuclear power plant in Spain. Dezincification originated by biofouling and MIC was studied using imped…
The highly flexible plasma system allows the independent flow control of plasma gas, carbonaceous feedstock and metal catalyst. Further important control parameters include current intensity and product quenching rate yielding in an excellent control of the thermal history of the carbon products. Temperature profiles…
We present a simulation tool to study fluid mixtures that are simultaneously chemically reacting and adsorbing in a porous material. The method is a combination of the reaction ensemble Monte Carlo method and the dual control volume grand canonical molecular dynamics technique. The method, termed the dual control cell…
This study investigates the different nanocapsules (NCs) made of poly-epsilon-caprolactone (PCL) containing the lipophilic sunscreen Escalol 557 [octyl methoxycinnamate (OMC)] and analyzes the influence of nanoparticle-based systems on light-induced decomposition of the sunscreen agent. The NCs were designed and prepa…
Within the lattice constants ranging from 3.5 to 4.28 \AA{}, we predict that manganese carbide (MnC) will possess a coexistent phase of periodic magnetic moments contributed by the semiconducting majority spin states and itinerant electrons in the minority spin channel. We analyze the effects of hybridization between…
We present Monte Carlo simulations of diskotic molecules using the Gay-Berne potential in a slab geometry. The disk-wall interaction is described by two different functions according to whether or not the equilibrium distance is dependent on the relative orientation of the disk to the wall. Furthermore, by changing th…
Photoluminescence (PL) from singlet oxygen generated by energy transfer from porous $\mathrm{Si}$ is observed at room temperature in an organic solvent. The evidence of the indirect excitation by energy transfer is obtained from PL excitation spectroscopy. The excitation spectrum indicates that by using porous $\mathr…
In the present research, we investigated the use of paramagnetic liposomes as contrast agents (CAs) for the detection of solid tumors. The liposomes were sterically stabilized by a polyethylene glycol (PEG) coating, and their size was constrained to approximately 100 nm. Dimyristoyl-sn-glycero-3-phosphoethanolamine-N-…
A new technique for detecting the presence and severity of inter-laminar short circuits as well as estimating the status of core compression (or looseness) in laminated magnetic cores of synchronous generators, with a single test equipment is demonstrated in this paper. The core loss measurement obtained from a flux i…
The observed macroscopic anisotropic properties such as the components of infrared (IR) absorbances of liquid crystals are expressed in terms of the order parameters of the long molecular axis, molecular, and phase biaxiality. The order parameters of the organo-siloxane tetrapode liquid crystal of zero dendritic order…
We present the electronic and vibrational spectra of quasi-one-dimensional $\frac{3}{4}$-filled ${(\mathrm{EDO}\text{\ensuremath{-}}\mathrm{TTF})}_{2}X$ ($\mathrm{EDO}\text{\ensuremath{-}}\mathrm{TTF}=\text{ethylenedioxy-tetrathiafulvalene}$, $X={\mathrm{PF}}_{6}$ and ${\mathrm{AsF}}_{6}$) above and below the metal-in…
We present a density functional theory study of colloidal interactions in a concentrated polymer solution. The colloids are modeled as hard spheres and polymers are modeled as freely jointed tangent hard sphere chains. Our theoretical results for the polymer-mediated mean force between two dilute colloids are compared…
Sonoluminescence is the light emission phenomenon from collapsing bubbles in liquid irradiated by an ultrasonic wave. In the present review, theoretical and experimental studies of the two types of sonoluminescence [single‐bubble sonoluminescence (SBSL) and multibubble sonoluminescence (MBSL)] are described. SBSL is a…
Abstract Between composite materials, shape memory alloy (SMA) composites are having a more and more relevant role. Typically, SMA wires are embedded in a metallic or a polymeric matrix to obtain materials with native multi‐functionality and adaptive properties. This work approaches the computational study of the mech…
An efficient algorithm is presented for numerically evaluating a self-consistent field theoretic (SCFT) model of an AB diblock copolymer that incorporates continuous polydispersity in one of the blocks. An interesting segregation effect is found in which chains of intermediate molecular weight are concentrated at doma…
