Near-field imaging of an engineered double layer structure in transmission mode has shown enhancement of light intensity through the structure. An array created by an optically thick double layer structure of a total thickness of 165 nm containing twin 50 nm Au layers was imaged using a near-field scanning optical microscope in illumination mode. The resulting transmission image shows an increa...

To investigate the energy absorption characteristics and crush behavior of layered aluminum honeycomb, the experiments of layered aluminum honeycomb structure under quasi-static load had been carried out, mainly includes single, double, triple, four layer combinations. The results showed that: the peak force and the mean plateau force of single-layer aluminum honeycomb structure are proportiona...

In this paper, piezoresistive properties of resonant tunneling structure made of undoped InGaAs/AlAs double-barrier quantum layers have been experimentally investigated, and the resonant tunneling structure was grown by molecular beam epitaxy (MBE) on semi-insulation (001)-oriented GaAs substrate. We found that the piezoresistivity of such quantum layers is about one order higher than that of t...

In the title salt, C6H9ClN3 (+)·C6H3O4S(-), the cations and anions are linked via O-H⋯O and N-H⋯O hydrogen bonds, forming R 6 (6)(37) ring motifs that are inter-connected with each other, producing sheets. Separate parallel inversion-related sheets are linked through N-H⋯N and π-π stacking inter-actions [centroid-centroid distance = 3.5414 (13) Å], forming double layers parallel to (101). Weak ...

The PANDA collaboration intends to build a state-of-the-art detector to study the physics of antiproton annihilation in the charm mass region at the future FAIR facility at GSI, Darmstadt. One major part of the PANDA detector is the straw tube tracker. It will consist of about 6000 individual straws grouped in 11 double layers and filled with an Ar+10% CO2 gas mixture. The required radial spati...

X-ray scattering by multiferroic LuFe2O4 is reported. Below 320 K, superstructure reflections indicate an incommensurate charge order with propagation close to (1/3 1/3 3/2). The corresponding charge configuration, also found by electronic structure calculations as most stable, contains polar Fe/O double layers with antiferroelectric stacking. Diffuse scattering at 360 K, with (1/3 1/3 0) propa...

In the anion of the title compound, (C7H11N2)[CoCl3(C7H10N2)], the Co(II) ion is coordinated by one N atom from a 4-(di-methyl-amino)-pyridine (DMAP) ligand and three Cl atoms, forming a CoNCl3 polyhedron with a distorted tetra-hedral geometry. In the crystal, cations and anions are linked via weak N-H⋯Cl and C-H⋯Cl hydrogen bonds. Double layers of complex anions stack along the b- axis directi...

In the title compound, [Cu(C(7)H(5)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)]·H(2)O, the Cu(II) atom is in a distorted square-pyramidal environment. The mol-ecules are assembled into double chains extending along [010] by N-H⋯O hydrogen bonds. These double chains are linked by O-H⋯O hydrogen bonds, forming layers parallel to (02); the layers are linked into a three-dimensional network by van der Waals i...

Three homologous saturated phosphatidylcholines were studied by electron microscopy after tricomplex fixation. The results are compared with those obtained by x-ray diffraction analysis of the same and some other homologous compounds, in the dry crystalline state and after tricomplex fixation. By electron microscopy alternating dark and light bands are observed which are likely to correspond to...
