The combination of cryo-microscopy and electron tomographic reconstruction has allowed us to determine the structure of one of the more complex viruses, intracellular mature vaccinia virus, at a resolution of 4-6 nm. The tomographic reconstruction allows us to dissect the different structural components of the viral particle, avoiding projection artifacts derived from previous microscopic obser...

ZnO thin films with preferred orientation along the (002) plane were prepared onto the glass substrates by the sol-gel spin coating method for different post- annealing temperatures. The XRD study confirms that the thin films grown by this method have good crystalline hexagonal wurtzite structure. The optical band gap of the samples was determined from UV-visible spectra. It is found that the s...

A new hexagonal bipyramidal Ni8 cluster is reported and its magnetic behaviour is analyzed. The molecular structure consists of a hexagonal wheel capped by two additional apical Ni(2+) ions. This structure supports ferromagnetic superexchange interactions between adjacent Ni(2+) ions in the wheel and an antiferromagnetic superexchange interaction between the wheel and apical Ni(2+) ions.

TEM analysis of mesoporous materials is generally undertaken to give qualitative results. Accurate quantitative analysis is demonstrated in this study. A systematic image analysis of a powder form of a hexagonal mesoporous material known as KIT-6 is conducted using a transmission electron microscope (TEM). Three types of image contrast typically appear in this material (a hexagonal honeycomb st...

Microstrip patch antennas is one of the most used for wireless communication. Its key features include a limited bandwidth, low cost, and ease manufacture. This paper describes about design microstrip antenna over frequency range 3.1 GHz to 10.6 UWB applications. The substrate material chosen FR4, having loss tangent 0.02, dielectric constant 4.4, thickness 1.59 mm. work presents with hexagonal...

A neutron diffraction method applicable to nonlamellar phases of substrate-supported lipid membranes is described and validated. When prepared on a flat substrate, the resulting nonlamellar phases have layered symmetry which provides some advantages over powder diffraction for detailed structure determination. This approach recently led to the detection of a rhombohedral phase and a distorted h...

The internal structure of DNA-CTAB and DNA-DDAB is investigated by a Small Angel X- ray Scattering(SAXS) instrument. Hexagonal packing of DNA was observed for DNA complex with CTAB, and for DDABcomplex is observed lamellar structure. Variations in the internal spacing and degree of long-range ordering aredependent on both surfactant type and concentrations of added salt. When we increased the a...

A compact semi-hexagonal-shaped MIMO antenna loaded with a planar SRR (split-ring resonator) structure is presented for Terahertz applications. The single radiating element consists of semi-hexagonal shape metallic patch SRR-CC (Split ring Resonator-Connected C shape) metamaterial unit cell to enhance the impedance bandwidth as well gain proposed antenna. can be easily extended into two-port an...
