Miniaturized microreactors enable photochemistry with laser irradiation in flow mode to convert azidobiphenyl into carbazole with high efficiency.
The influence of endophyte fungus piriformospora indica on characteristics of the growth, water status, photosynthetic pigments concentration, gas exchange, and chlorophyll fluorescence of tomato plants under salt stress (0, 50, 100 and 150 mM) was studied in the greenhouse. Under salt stress, mycorrhizal tomato plants had higher dry weight of shoot and root, higher height, higher carotenoid an...
Astaxanthin (AXT) is a natural carotenoid which provides colorations to numerous living species such as salmon. Owing to its chelate function deprotonated astaxanthin (axt−) should be easily attached to metal ions. The complex Rh(phpy)2(axt) with phpy− = deprotonated 2-phenylpyridine was prepared, and its electronic spectra and photochemistry were examined and compared to that of free AXT. Alth...

Deposition of metals on TiO2 semiconductor particles (M-TiO2 ) results in hybrid Janus objects combining the properties of both materials. One of the techniques proposed to generate Janus particles is bipolar electrochemistry (BPE). The concept can be applied in a straightforward way for the site-selective modification of conducting particles, but is much less obvious to use for semiconductors....
Two new cyclic trisilanes containing a SiMePh moiety in the central position have been synthesized, and their photochemistries studied by steady-state and laser flash photolysis methods. The yield of the transient silylene SiMePh increases at the expense of that of the corresponding cyclic silene derivative (formed by photochemical 1,3-silyl migration into the phenyl ring) as the ring size is d...
