Crystal is a programming language with the following goals: Have a syntax similar to Ruby (but compatibility with it is not a goal) Statically type-checked but without having to specify the type of variables or method arguments. Be able to call C code by writing bindings to it in Crystal....
In NaCoD the moments are in the bc-plane, M(y) = 2.51(2) μ(B) and M(z) = 1.29(4) μ(B), with the major component along the cobalt chain and the resultant moment, 2.83(3) μ(B), making an angle of 27° with the b-axis. The sum of the moments within the cell is ...

Colloidal crystal engineering with nucleic acid-modified nanoparticles is a powerful way for preparing 3D superlattices, which may be useful in many areas, including catalysis, sensing, and photonics. To date, the building blocks studied have been primarily based upon metals, metal oxides, chalcogenide...
An ionic crystal K2[Cr3O(OOCC2H5)6(H2O)3]2[α-SiW12O40]·3H2O (1a) is synthesized by the complexation of a Keggin-type polyoxometalate of [α-SiW12O40]4- with K+ and a macrocation of [Cr3O(OOCC2H5)6(H2O)3]+. Compound 1a possesses both hydrophilic and hydrophobic channels in th...
The changes of thermodynamic properties for the formation of the title compound with the temperature ranging from 200 to 500 K have been obtained using the statistical thermodynamic method. At 298.15 K, the change of Gibbs free energy for the formation reaction of the title compound is -824.841 ...
With a field-emission scanning electron microscope (FESEM, ZEISS Gemin) with an accelerating voltage of 15 kV, the dried sample's morphologies were characterized. X-ray photoelectron spectroscopy (Thermo Fisher Scientific K-Alpha) was used to obtain XPS spectra. Fourier transform infrared spectroscopy...
