Self-assembly of the sodium molybdate
copper chloride and glycine in
aqueous solution results in a novel
compound

(6)(Gly)(8)(H(2)O)(2)}{
Mo(8)O(26)(GlyH)(2))center dot 16H(2)O (1).
Compound 1 contains a new unit of
{[NaCu(6)(Gly)(8)(H(2)O)(2)][Mo(8)O(26)Cu(Gly)(2)I(2))
in
which the
[Mo(8)O(26)Cu(Gly)(2)] polyoxometalate units are connected by the
[NaCu(6)(Gly)(8)(H(2)O)(2)] hexanuclear
copper cluster. The magnetic
measurement of 1 shows that ferromagnetic coupling exists between the
magnetic centers of the hexanuclear copper cluster. (C) 2011 Elsevier BV

To realize the functions of infrared transparent as well as radar double- pass Band
A Y loop and Y slot compound element Frequency Selective Surface (FSS) structure is proposed
which takes an infrared transparent inductive mesh as a substrate. The proposed structure is analyzed based on Galerkin spectral method. The transitivity of infrared (3um-5um) as well as the radar double passed band with two resonance frequencies (31GHz and 54GHz) is discussed. The result reveals that this structure has function of infrared transparent as well as stable radar double-band filter with effective shielding effect on S-band and C-band radar electromagnetic waves. The design with multiple passband is suitable for radar/IR composite guidance and it also offers a kind of new thinking way of design for multi-mode compound guidance systems. 2011 Trans Tech Publications.

A new design of compound Fresnel-R concentrator is presented which is composed of two lenses: a primary lens (Fresnel lens) that works by total internal reflection at outer facets but refraction at inner facets
and a secondary lens that works by refraction. In contrast to previous Fresnel lens concentrator
this design increases the acceptance angle
improves the irradiance uniformity on the solar cell
and reduces the aspect ratio significantly. Another outstanding advantage of this concentrator is the fact that it mainly works by performing total internal reflection
reducing chromatic dependence as well as Fresnel losses. An optical efficiency more than 80% can be achieved. Moreover
in order to reduce the influence of manufacture accuracy and to increase the optical efficiency further
the central part of the bottom of the secondary lens which directly adhered to the solar cell is designed as a cone-shaped prism to collect the sunlight that doesn't reach the solar cell. 2010 SPIE.

Compound telescope is a new type of space optical system. It uses the concept of compound eyes and the property of diffractive lens. With the help of diffractive lens
the diffractive optical system could become lighter weight
lower cost
and looser tolerance. And with the help of compound-eye configuration
the field of view is expanded. A design example of compound diffractive optical system is given. It is composed of many diffractive telescope of F/4
200mm aperture
0.1 degrees field of view. It is shown that the whole system can approximately attain the diffraction limit over wide field of view.
