The hexagermane Pr(i)3Ge(GePh2)4GePr(i)3 has been synthesized and is not only the first such linear oligogermane to be structurally characterized but also is the first such compound to exhibit fluorescence and dichroic properties when observed under different orientations of plane polarized visible light.

A dynamic smart surface which was constructed by the self-assembly of an azobenzene-functionalised pillar[5]arene exhibits reversibly responsive morphologies towards UV and visible light as observed by TEM, SEM and AFM.

Fully reversible photoswitching of the coordination mode of the ligand MeN4Py (1,1-di(pyridin-2-yl)-N,N'-bis(pyridin-2-yl-methyl)-ethan-1-amine) in its ruthenium(II) complex with visible light is reported. Irradiation with visible light results in dissociation of a pyridyl moiety, which is reversed by irradiation at 355 nm.

Gold-coated diarylethene crystals exhibited photoreversible bending upon alternating irradiation with ultraviolet (UV) and visible light. The bending behavior can be well explained by the extended bimetal model, which we propose here. Moreover, we have demonstrated that it can be used as an actual electrical circuit photoswitch.

An optical procedure is presented to measure at the speckle size and with high accuracy, the polarization degree of patterns scattered by disordered media. Whole mappings of polarization ratio, polarimetric phase and polarization degree are pointed out. Scattered clouds are emphasized on the Poincaré sphere, and are completed by probability density functions of the polarization degree. A specia...

in  this  reaserch,  photocatalyst  titanium  dioxide  was  doped  with silver  and modified  by  polyethylene  glycol  by  sol  gel method  and the  samples  were  characterized  by  x-ray  diffraction  (xrd)  and scanning  electron  microscopy  (sem).  the  purpose  of  the  present study  was  to  evaluate  the  photocatalytic  bactericidal  effects  of prepared nanocomposite on human pathog...

The detection probability of visible light reconnaissance equipment is one of key indexes to assess the performance of the system. The detection probability is determined by many factors, such as atmospheric visibility, target-background contrast, target size and distance, solar elevation angle etc. Based on the detection probability model of the visible light reconnaissance equipment to gain t...

a novel zr,ce-tio2/sio2 nanocomposite thin film was successfully prepared with various amounts of zr4+ and ce4+ as codopant ions for self-cleaning applications. a thin film was coated on a tile substrate by dip-coating and porous zr,ce-tio2/sio2 was obtained after heat treatment for 2 hours at 500 °c. the sem images and xrd pattern showed that the optimum amount of doping ions in relation to ti...

AM-6 with high intensity visible light absorption at 400-800 nm was synthesized via a hydrothermal route in the presence of F(-) ions. Structure characterization and DFT calculations indicate that the unusual optical properties originate from the connection of octahedral VO(6) wires with distorted tetrahedral VO(4) units, which are stabilized in the framework of AM-6.
