Magnetophotoluminescence reveals that the annealing increases the QD size, with a larger effect occurring along the growth axis, and decreases the carrier effective masses. The main contribution to the blueshift is deduced to be an increase in the average

Ga composition of the QDs. The inadvertent annealing which occurs during the growth of the upper AlGaAs cladding layer in laser structures is also studied.”
“One new precursor of tetraterpenoids, Sarglaucol (1), along with eight known compounds have been isolated from the soft coral Sarcophyton glaucum collected from the Sanya Bay, Hainan Island, China. Their structures were elucidated through spectroscopic techniques including 1D- and 2D-NMR, and their relative configurations were also assigned by NMR and NOESY analysis. Compounds 1 showed SB273005 clinical trial weak antitumour activities.”
“The study of modulated electron beams is important because they can be used to produce coherent radiation, but the modulations can cause unwanted instabilities in some devices. Specifically, in a free electron laser, proper prebunching at the desired emission frequency can learn more enhance performance, while bunching resulting from instabilities and bunch compression schemes can degrade performance.

In a photoinjector accelerator, tailoring the shape of the drive laser pulse could be used as a technique to either enhance or mitigate the effect of these modulations. This work explores the possibility of creating deeply modulated electron beams at the photocathode URMC-099 mouse by using a modified drive laser designed to produce multiple subpicosecond pulses repeated at terahertz frequencies. Longitudinal space charge forces can strongly influence the evolution of

modulations by converting density modulations to energy modulations. Experiments at the Source Development Laboratory electron accelerator at Brookhaven National Laboratory and PARMELA simulations are employed to explore the dynamics of electron beams with varying charge and with varying initial modulation. Finally, terahertz light generated by a transition radiator is used to confirm the structure of the electron beam.”
“The content of total polyphenols, chlorogenic, caffeic (CaA) and ferulic acids, and rutin, was investigated in plant organs of three introgression lines (IL7-3, IL10-1 and IL12-4) of Solanum pennellii in Solanum lycopersicum cv M82 and compared with that of cropped parental. Such study aims to evidence factors associated to the introgressions that can affect polyphenol distribution in plant. Among genotypes few differences in polyphenols were recorded on fresh weight basis. IL7-3 showed higher total polyphenols in fruits and lower rutin in leaves than the other genotypes. IL12-4 showed an increasing trend of total polyphenol concentration in fresh vegetative organs; however, this seems to depend on the lower water content rather than on a higher polyphenol biosynthesis in the genotype. IL10-1 sowed higher CaA and lignin contents in leaves.
