The impact of fs and ns pulses on indium and sulfur doped gallium selenide crystals with four and five different doping concentrations, respectively, has been studied in comparison with that of undoped GaSe. The inconsistence of the visual criterion of the damage threshold determination has been demonstrated. The multiphoton absorption and thermal effect have been identified as key factors limiting fs and ns pulse pump intensities, respectively. High advantages in the limit pump intensity as up to 50% for optimally indium-doped crystal and up to 4.5 times for optimally sulfur-doped crystal have been demonstrated under fs pulses expose.

In the title compound, [Ni(C8H5Cl2N3OS)(C12H8N2)(CH3OH)], the NiII atom is octahedrally coordinated by one N, one O and one S atom from a 3,5-dichloro-2-oxidobenzaldehyde thiosemicarbazonate ligand, another O atom from methanol and another two N atoms from 1,10-phenanthroline. The crystal structure is constructed by N—H...Cl, N—H...N, C—H...S and O—H...S hydrogen bonds.

Tumor vaccines are a novel approach to the treatment of malignancy, and are attracting the attention of the medical profession. Nanomaterials have significant advantages in the preparation of a tumor vaccine, including their ability to penetrate and target cancer tissue and their antigenic properties. In this review, we focus on several nanomaterials, ie, carbon nanotubes, nanoemulsions, nanosized aluminum, and nanochitosan. Applications for these nanomaterials in nanovaccines and their biological characteristics, as well as their potential toxicity, are discussed. [ABSTRACT FROM AUTHOR]

Modified carbon black (MCB) was obtained by oxidization and hydroxymethylation reactions with conductive carbon black (CB); in the MCB, some hydroxyl groups were introduced on the surface of the CB particles. CB, MCB, and a kind of organic ultraviolet absorber (UA) were used as UV antidotes, and binary composites and ternary composites were prepared by solvent casting with polystyrene, styrene–butadiene–styrene triblock copolymer, and poly(methyl methacrylate) as the matrix, respectively. In the binary composites, only one kind of UV antidote was used, whereas in the ternary composites, the organic and inorganic UAs were combined. The ultraviolet–visible absorption spectra of the composites were investigated extensively, and it was found that no synergism occurred when CB was combined with the organic absorber; on the other hand, an obvious synergism effect emerged when MCB was combined with the organic absorber in the same matrix, which was attributed to the formation of hydrogen bonds between MCB and UA. The interaction between MCB and UA was studied by Fourier transform infrared spectroscopy, differential scanning calorimetry, and transmission electron microscopy. © 2010 Wiley Periodicals, Inc.

Riemerella anatipestifer (RA) is the causative agent of septicemic and exudative disease for a variety of bird species. Although RA had been isolated from chickens, whether can bring damages to them is not unrevealed yet. In this study, we report a flock of SanHuang chickens infected by RA with 15% morbidity and less than 8% mortality. The infection is further substantiated by case duplicate. The tested chickens demonstrate typical signs of pericarditis, air sacculitis and perihepatitis that are completely consistent with the field outbreak. The results suggest that RA is pathogenic to SanHuang chickens, which can then be theoretically and practicably incorporated into its infection spectrum.
