Brownish platelet crystals of My(VO)9 + x(PO4)4x(HPO4)12 - 4x (M = Cs+, NH4+ and Rb+) were prepared hydrothermally. The structure of Cs approximately 5(VO)10(PO4)4(HPO4)8 was solved from single-crystal X-ray diffraction data in the centrosymmetric monoclinic space group C2/c (No....

Spaceborne estimate of atmospheric CO2 column by use of the differential absorption method: error analysis.

Appl Opt. 2003 Jun 20;42(18):3595-609. doi: 10.1364/ao.42.003595.

For better knowledge of the carbon cycle, there is a need for spaceborne measurements of atmospheric CO2 concentration. Because the gradients are relatively small, the accuracy requirements are better than 1%. We analyze the feasibility of a CO2-weighted-column estimate,...

Acta Crystallogr C. 2009 Jul;65:i36-8. doi: 10.1107/S0108270109021325. Epub 2009 Jun 13.

The title synthesized hypophosphite has the formula V(H(2)PO(2))(3). Its structure is based on VO(6) octahedra and (H(2)PO(2))(-) pseudo-tetrahedra. The asymmetric unit contains two crystallographically distinct V atoms and six independent (H(2)PO(2))(-) groups. The connection of the polyhedra generates [VPO(6)H(2)](6-)...
