The axial position of a magnetic field gradient has been varied for capacitive discharges in the linear plasma device VINETA. For low magnetic fields (B ≤ O(10 mT)), double layers have been observed to form predominantly at the interface between the source and the plasma chamber. In particular, double layer position is independent of the position of the magnetic field gradient. However, shiftin...

A facile enzyme-free hydrogenperoxide electrochemical sensorwas fabricated based onmultilayer ultrathin film containing Naphthol green B anions (NGB) and exfoliated nanosheets of Co–Al layered double hydroxide (LDH) via layer-by-layer self-assembly technique. The X-ray diffraction pattern indicates the superlattice structure of the filmwith repeating distance of 4.15nm; SEM and AFM images show ...

Layered double hydroxide (LDH) single-layer nanosheets were traditionally prepared through a multi-step exfoliation process which is very time-consuming and of low efficiency. Herein we report the preparation of LDH single-layer nanosheets through a facile direct synthesis method. By introducing a layer growth inhibitor, one can directly synthesize LDH single-layer nanosheets instead of LDH lay...

We report the preparation of monometallic Co(2+)/Co(3+) layered double hydroxide, intercalated with lactate anions (LCoH-Lactate), and its spontaneous delamination in water to form cobalt hydroxide nanosheets. These hydroxide nanosheets formed stable aqueous dispersions. The thickness of a nanosheet was estimated to be approximately 1 nm by atomic force microscopy and small angle X-ray scatteri...

A double discontinuity is a compound structure composed of a slow shock layer and an adjoining rotational discontinuity layer on the postshock side. We use highresolution data from Geotail and Wind spacecraft to examine the interior structure within the finite thickness of the discontinuity at the plasma sheet-lobe boundary and found that recognizable MHD structures at the boundary can be stand...

Iron oxide nanoparticles are suitable for biomedical applications owing to their ability anchor various active agents and drugs, unique magnetic properties, nontoxicity, biocompatibility. In this work, the physico-chemical as well cytotoxicity, of Fe3O4 coated with a polymeric carrier loaded 5-fluorouracil (5-FU) anti-cancer drug discussed. The synthesized were polyvinyl alcohol Zn/Al-layered d...

the nonlocal nonlinear buckling of a double layer graphene sheet (dlgs) covered by zinc oxide (zno) piezoelectric layers is investigated in this study. the surrounding circumstances of the system are considered as a pasternak foundation including spring constants and a shear layer. graphene sheets are subjected to longitudinal magnetic field and biaxial forces. on the other hand, the zno piezoe...

The reaction of Nevada opal with calcium hydroxide, potassium and lithium hydroxide solutions was investigated. In addition opal was exposed to a combined solution of these three hydroxides. The progress of the three reactions was followed using X-ray Diffraction (XRD), 29 Si Nuclear Magnetic Resonance (NMR) and Scanning Electron Microscopy (SEM). The XRD results indicated the presence of a low...

The magnetic properties response of the layered hybrid material copper hydroxide acetate Cu2(OH)3CH3COO·H2O is studied as a function of the applied pressure within first-principles molecular dynamics. We are able to elucidate the interplay between the structural properties of this material and its magnetic character, both at the local (atomic) level and at the bulk level. We performed a detaile...
