We propose that domain inversion can be directly induced by femtosecond laser both theoretically and experimentally, which opens a path to achieve three-dimensional (3D) nonlinear crystal with a period in sub-micron-scale. A simulation of domain inversion is modeled by considering the temporal distribution of femtosecond pulses. The calculation results clarify that the domain inversions can hap...

The asymmetric unit of the title compound, [Ag(C(5)H(6)N(2))(2)]NO(3), consists of one and a half each of both cations and anions, the other halves being generated by crystallographic inversion centres. One of the Ag(I) atoms lies on an inversion center and one of the nitrate ions is disordered across an inversion center. Each Ag(I) atom is bicoordinated in a linear geometry by two N atoms from...

We combine traction force data with Bayesian inversion to obtain an absolute estimate of the internal stress field of a cell monolayer. The method, Bayesian inversion stress microscopy, is validated using numerical simulations performed in a wide range of conditions. It is robust to changes in each ingredient of the underlying statistical model. Importantly, its accuracy does not depend on the ...

The title compound, [NH3(CH2)4NH3](2+)·SiF6 (2-), is a hybrid built from an organic butane-1,4-di-ammonium dication linked to a hexa-fluoro-silicate mineral anion. Both ions posses inversion symmetry. In the anion the Si atom is located on an inversion center, while in the cation the center of inversion is situated at the mid-point of the central -CH2-CH2- bond. The Si atom is surrounded by six...
