Nonlinear electromagnetic stabilization by suprathermal pressure gradients found in specific regimes is shown to be a key factor in reducing tokamak microturbulence, augmenting significantly the thermal pressure electromagnetic stabilization. Based on nonlinear gyrokinetic simulations investigating a set of ion heat t…
Nanostructured magnetic systems have many applications, including potential use in cancer therapy deriving from their ability to heat in alternating magnetic fields. In this work we explore the influence of particle chain formation on the normalized heating properties, or specific loss power (SLP) of both low- (spheri…
Exciton generation, migration, and dissociation are key processes that play a central role in the design and operation of many organic optoelectronic devices. In organic photovoltaic cells, charge generation often occurs only at an interface, forcing the exciton to migrate from the point of photogeneration in order to…
Power up: The photoelectrochemical performance of hematite in a water-splitting device was improved significantly through surface modification with amorphous NiFeOx (see graph showing the large cathodic shift observed; FTO=fluorine-doped tin oxide). The measured photovoltage increased from 0.24 to 0.61 V, which yielde…
Electrical wave mechanics: A newly designed triboelectric nanogenerator is based on the contact electrification between a patterned polydimethylsiloxane pyramid array and water. Cost-effective and simple, the prototype triboelectric nanogenerator shows the potential to harvest energy from liquid waves and serve as che…
In the past few years the automotive industry has shown an increasing concern on safety issues and predicting the right behavior of vehicle structures under crash situations has been a great preoccupation. CAE has a major role in crash validations, especially when predicting the rupture of fuel tanks, since avoiding a…
Piezochromism describes a tendency of certain materials changing colors when they are subjected to various pressure levels. It occurs particularly in some polymers or inorganic materials, such as in palladium complexes. However, piezochromism is generally believed to work at high pressure range of 0.1-10 GPa. This res…
In the middle of the global competition, inside the automotive sector, the perceived quality of costumers, related to the beauty and harmony of the outer skin surfaces of motor vehicles, has become one of the main determinant factors in the purchase process decision. In general, the initial perceived quality of a car…
In this work, we study the photoluminescence and the Raman scattering behavior of Si rich silicon oxynitride films obtained by plasma enhanced chemical vapor deposition as a result of thermal anneals during 1 hour in the temperature range from 400O to 1100OC and discuss the ways of the transformation of structure in t…
A novel chemical approach was established to produce carbon nanotube/Nylon‐6,6 hybrid materials from readily available substrates, that is, Nylon‐6,6 salt and oxidized multiwall carbon nanotubes (O‐MWCNTs). The key synthetic precursor hexane‐1,6‐diaminium adipate and “carbon nanotubate”—“Binary nanotube salt”—was obta…
Using density functional theory, magnetoelectric (ME) effect for [001]-oriented Co2MnSi/PbTiO3 ultrathin bilayer is demonstrated by changing interface configuration. Within paraelectric state, the interfacial stability is argued by phase diagram. With the reversal of electric polarization, the favorable change in loca…
In order to comply with the introduction of new emission limits, motorcycles have been equipped with electronic injection systems and three-way catalytic converters for emissions abatement. However, these converters produce unwanted reactions, such as the formation of ammonia. This paper was focused on ammonia emissio…
The most anti-aromatic 16π porphyrin, an octaethylporphyrin (OEP) zinc(II) complex with no substituents at the meso-positions was generated as a highly unstable species from the reaction of the corresponding 18π porphyrin using strong oxidants such as AgSbF 6/ I 2 or SbF 5. The porphyrin showed a significant blue-shif…
Single-bubble sonoluminescence (SBSL) spectra from aqueous sulfuric acid solutions containing dissolved neon show widely varying emission despite being similar in chemical composition. From a 65 wt % solution, emission from hydroxyl radicals is observed, with the rovibronic progression being well-described by a single…
The wet strength of handsheets subjected to dipping treatment by solutions such as glyoxal with Zn(NO 3 ) 2 as a catalyst, chitosan, and the crosslinking system of glyoxal and chitosan is studied in this paper. The crosslinking system achieved better wet strength performance than glyoxal or chitosan alone and slightly…
Poly(lactic acid) (PLA)/palygorskite (PA) nanocomposites were fabricated through melt blending. The significant finding by Fourier transformed infrared spectra and X‐ray photoelectron spectroscopy was that the hydrogen bonding interaction between PA surface and PLA matrix. Due to the hydrogen bonding interaction, the…
As at nano/micro-scale van der Waals forces often dominate various other types of forces, the accurate adhesion characterization of graphene (Gr) is essential to its processing, manipulation, and possible integration into integrated circuits and other nano/micro-scale devices. Since 2010, the reported (experimental) a…
Absorption zeigt Absorption an: Die Oberflächenplasmonenresonanzbande von tetrahexaedrischen, oktaedrischen und kubischen Au/Pd-Kern/Schale-Nanokristallen wird bei Absorption von Wasserstoff in die Pd-Schale stark rotverschoben. Diese reversible Spektralverschiebung könnte für die Entwicklung von Sensoren für Wasserst…
Abstract We fabricated flexible n ‐type carbon nanotube thin‐film transistors on a plastic film by a simple transfer process and a solution‐based chemical doping technique with polyethyleneimine (PEI). There exists an optimal PEI concentration, which is determined by doping level and charge accumulation in the PEI lay…
The structure differences of magnetoelectric (ME) laminates for passive and active mode sensors are discussed. The Fourier coefficient A1 calculated from the data of αME-Hdc indicates that N = 1 (where N is the number of Metglas layers) should be the optimum structure for the active mode. Experimental investigations o…
