Template-free CuO nanorods were synthesized through a three-step chemical method with no water-insoluble materials. The first step included the preparation of a Cu-complex, which was obtained from dipicolinic acid, L-lysine, and copper nitrate. Then, as the second step, the obtained solution was allowed to be relaxed for a week to and formation of some blue single-crystals single crystals, whic...

A series of lanthanide complexes [Ln(dpxCy)3](3-) have been synthesised. The ligands are composed of a coordinating dipicolinic acid backbone decorated with a polyoxyethylene arm fitted with a coumarin moiety at its extremity. The nature of the coumarin as well as the length of the linker have been varied. Upon excitation at 320 nm, the coumarin exclusively acts as an antenna while the dipicoli...

Heat shock of dormant spores of Bacillus stearothermophilus ATCC 7953 at 100 or 80 degrees C for short times, the so-called activation or breaking of dormancy, was investigated by separating the resulting spores by buoyant density centrifugation into a band at 1.240 g/ml that was distinct from another band at 1.340 g/ml, the same density as the original spores. The proportion of spores at 1.240...

Micro-Raman spectroscopy combined with optical tweezers is a powerful method to analyze how the biochemical composition and molecular structures of individual biological objects change time. In this work we investigate laser induced effects in trapped object. Bacillus thuringiensis spores, which are robust organisms known for their resilience light, heat, chemicals used study. We trap spores mo...
