    ABSTRACT: In this paper, indium doped SnO2 nanorods and nanowires have been prepared by the molten salt method, and the effects of indium doping concentration on the morphology and electrical properties of one-dimensional (1D) SnO2 nanostructures have been studied. It is found that indium doping concentration can affect the epitaxial growth, morphology and the electrical conductance of 1D SnO2 nanostructures. It is also found that the element made by using 6 mol% indium doped SnO2 nanorods responds to nitrogen gas.

    ABSTRACT: ZnO nanorod array coating is a novel kind of solid-phase microextraction (SPME) fiber coating which shows good extraction capability due to the nanostructure. To prepare the composite coating is a good way to improve the extraction capability. In this paper, the ZnO nanorod array polydimethylsiloxane (PDMS) composite SPME fiber coating has been prepared and its extraction capability for volatile organic compounds (VOCs) has been studied by headspace sampling the typical volatile mixed standard solution of benzene, toluene, ethylbenzene and xylene (BTEX). Improved detection limit and good linear ranges have been achieved for this composite SPME fiber coating. Also, it is found that the composite SPME fiber coating shows good extraction selectivity to the VOCs with alkane radicals.

    ABSTRACT: The magnetic properties of the LaFeO3 nanospheres and nanotubes prepared by using the molten salt method have been investigated by magnetization measurements. The zero-field-cooled (ZFC) curve for the LaFeO3 nanospheres exhibits a maximum at 44 K while the ZFC curve for the LaFeO3 nanotubes exhibits two maxima: one, at 48 K, and the other, at 5 K. The maximums at 44 K and 48 K are ascribed to the average blocking temperature of the core moment. The maximum at 5 K in the ZFC curves for the LaFeO3 nanotubes and the rapid increase of magnetization below 10 K in the field-cooled (FC) curves for the LaFeO3 nanotubes are attributed to the surface spin freezing and the tube morphology. Hysteresis loops for the LaFeO3 nanospheres and nanotubes are measured. Loop shift for the LaFeO3 nanospheres is observed and discussed.

    ABSTRACT: In this paper, a ZnO nanorod array has been introduced as a coating to the headspace solid phase micro-extraction (HSSPME) field. The coating shows good extraction capability for volatile organic compounds (VOCs) by use of BTEX as a standard and can be considered suitable for sampling trace and small molecular VOC targets. In comparison with the randomly oriented ZnO nanorod HSSPME coating, ZnO nanorod array HSSPME fiber coating shows better extraction capability, which is attributed to the nanorod array structure of the coating. Also, this novel nanorod array coating shows good extraction selectivity to 1-propanethiol.

    ABSTRACT: In this work, a combination sampling method, including headspace solid-phase microextraction (HSSPME) and steam distillation (SD), was used to study the oyster volatiles during storage followed by GC–MS detection. Twenty and twenty seven volatile compounds of fresh and deteriorated oysters were identified respectively by HSSPME, and 16 oyster volatiles were isolated by SD. HSSPME and SD were suitable for low-boiling-point and high-boiling-point volatiles, respectively. Therefore, the combination of HSSPME and SD could obtain more species of oyster volatiles during storage than any single method. Different volatile profile characteristics during oyster storage obtained by HSSPME were specified by principal component analysis. The top ten volatiles contributing most to the difference of oyster volatile profile characteristics during storage were distilled by common model analysis. The results tentatively suggested that the difference of entire volatile profile characteristics during oyster storage would provide more precise alarming information for oyster deterioration during storage than individual volatiles.
