Models of red sprites and blue jets based on the concept of the streamer‐leader mechanism of the air breakdown are presented. Red sprites are interpreted as the downward streamers of varying cross sections launched from plasma patches in the lower ionosphere, which are caused by the electric field generated by the lig…

In this report, we have investigated the correlations between structure and light-induced electron transfer of one known and three new axially coordinated cobaloxime-based supramolecular photocatalysts for the reduction of protons to hydrogen. Solution-phase X-ray scattering and ultrafast transient optical spectroscop…
In this paper, a Y-Δ hybrid connection for a high-voltage induction motor is described. Low winding harmonic content is achieved by careful consideration of the interaction between the Y- and Δ-connected three-phase winding sets so that the magnetomotive force (MMF) in the air gap is close to sinusoid. Essentially, th…
Silver nanorod (AgNR) array substrates are investigated to detect pure melamine dissolved in 50% methanol using surface-enhanced Raman spectroscopy (SERS). We find that sample preparation conditions have a great influence on melamine detection. When the samples are prepared under a nitrogen glove box, the SERS charact…
The non-equilibrium structural and dynamical properties of a semiflexible polymer confined in a cylindrical microchannel and exposed to a Poiseuille flow is studied by mesoscale hydrodynamic simulations. For a polymer with a length half of its persistence length, large variations in orientation and conformations are f…
Recently we found epitaxial Fe-deficient yttrium iron garnet Y3Fe5−tO12−3t/2 (YIG) films pulsed laser deposited onto the (111) and (001) face of Gd3Ga5O12 single crystal experience, respectively, strong rhombohedral and tetragonal distortions and possess unusual magnetic anisotropy. Using the crystal field theory, we…
Abstract Cationic (arene)ruthenium‐based tetranuclear complexes of the general formula [Ru4(η6‐p‐cymene)4(μ‐N∩N)2(μ‐OO∩OO)2]4+ were obtained from the dinuclear (arene)ruthenium complexes [Ru2(η6‐p‐cymene)2(μ‐OO∩OO)2Cl2] (p‐cymene=1‐methyl‐4‐(1‐methylethyl)benzene, OO∩OO=5,8‐dihydroxy‐1,4‐naphthoquinonato(2−), 9,10‐dih…
Abstract Objectives Lipid-based liquid crystals formed from phytantriol (PHY) and glyceryl monooleate (GMO) retain their cubic-phase structure on dilution in physiologically relevant simulated gastrointestinal media, suggesting their potential application as sustained-release drug-delivery systems for poorly water-sol…
AIM: The purpose of this study was to formulate praziquantel (PZQ)-loaded hydrogenated castor oil (HCO) solid lipid nanoparticles (SLN) to enhance the bioavailability and prolong the systemic circulation of the drug. MATERIALS & METHODS: PZQ was encapsulated into HCO nanoparticles by a hot homogenization and ultrasoni…
The use of silver in the past demonstrated the certain antimicrobial activity, though this has been replaced by other treatments. However, nanotechnology has provided a way of producing pure silver nanoparticles, and it shows cytoprotective activities and possible pro-healing properties. But, the mechanism of silver n…
In scanning thermal microscopy (SThM) techniques, the thermal exchange radius between tip and sample is a crucial parameter. Indeed, it limits the lateral spatial resolution but, in addition, an accurate value of this parameter is necessary for a precise identification of thermal properties. But until now, the thermal…
A 3-V, 6-bit DAC is designed using complementary organic thin-film transistors on a glass substrate. The p-channel and n-channel transistors utilize dinaphthothienothiophene (DNTT) and hexadecafluorocopperphthalocyanine (F16CuPc) as the organic semiconductors, respectively. A low-temperature process compatible with fl…
DOI: 10.2514/1.46182 The combustion of Si- and Al-based systems using polytetrafluoroethylene (PTFE) as the oxidizer and Fluorel FC 2175 (a copolymer of hexafluoropropylene and vinylidene fluoride) as a binder has been studied. Experimental data were obtained using two methods: 1) instrumented tube burns and 2) presse…
The first 24 and 30 GHz band thin-film bulk acoustic resonator (FBAR) filters are reported in this paper. The filters were configured with air-gap-type FBARs on a flat silicon substrate. They were designed using a Butterworth–Van-Dyke (BVD) equivalent circuit considering the linear relationship between resonant freque…
Gold recovery from dilute solutions has always been a subject of great interest due to ever increasing demand of this precious metal. In the present study, an attempt had been made to recover this noble metal in ionic, nanocrystalline, and metallic form using a combination of biosorption, biocrystallization, and pyro-…
Recently,$\hbox{SiO}_{2}$grown at low temperatures has been highlighted for a range of applications. In this letter,$\hbox{SiO}_{2}$films were deposited at 280$^{\circ}\hbox{C}$by plasma-enhanced atomic layer deposition (ALD) using bis-diethylamino-silane and$\hbox{O}_{2}$plasma. The electrical conduction mechanisms o…
We carried out the temperature (22–350 K) and magnetic field (0.05 and 1.4 T) dependent Hall mobility and carrier density measurements on Al0.22Ga0.78N/GaN heterostructures with AlN interlayer grown by metal-organic chemical-vapor deposition. Hall data is analyzed with a simple parallel conduction extraction method an…
Metal-based glyconanoparticles (GNPs) are biofunctional nanomaterials that combine the unique physical, chemical and optical properties of the metallic nucleus with the characteristics of the carbohydrate coating. The latter characteristics comprise a series of advantages that range from ensuring water solubility, bio…
The role of band bending on the efficiency of charge transfer across the TiO 2 (110) single crystal surface has been measured in ultrahigh vacuum, in the absence of a wide range of surface site inhomogeneities, surface impurities and solvent effects, and particle size effects. The adsorption of the Cl 2 (electron acce…
