ABSTRACTRapid sample preparation is a key step in the field of food safety. A mechanical high-pressure method using a laboratory-made meat press machine was first introduced in this study to process the incurred muscle samples of chicken and rabbit. By applying high pressure to animal muscle, the meat juice was obtained. After extraction and purification, veterinary drug residues in the juice were qualitatively and quantitatively analyzed by using high-performance liquid chromatography–tandem mass spectrometry. The sample press conditions and extraction solvents were optimized. Under the optimal conditions, all veterinary drug residues, including tetracycline, enrofloxacin, clenbuterol, ampicillin, lincomycin, erythromycin, and sulfadiazine, in the incurred samples were detected. The residual concentration of drugs in samples obtained by using the mechanical high-pressure method can reach up to 94.0% of that obtained by using the common homogenization method, suggesting that drug residues exist in the tissue juice, which justifies the use of the mechanical high-pressure method. Moreover, with the mechanical high-pressure method, the sample preparation time was shortened by five times, and the consumption of the extraction solvent was reduced by 50%, relative to the homogenization method.

Storage Properties

Hydrogenation / dehydrogenation properties of a series of ternary face centered cubic (FCC) hydrides “Mg7MHx” (M = Sc, Ti, V, Zr, Nb, Hf and Ta), which were prepared by a high-pressure technique, were investigated. Differential scanning calorimeter (DSC) measurements under hydrogen atmosphere revealed that these hydrides exhibited reversible hydrogen releasing and re-storing properties at around 600 and 560 K, respectively. These releasing temperatures are lower by 100 ~ 120 K than that of MgH2. Furthermore, pressure-composition isotherm at 523 K shows that these FCC hydrides release 3.8 - 5 wt. % hydrogens.
