A flexible fiber acoustic transducer is created by designing a parallel configuration of a Rubidium iron boron (NdFeB) magnet fiber and an aluminum fiber. The former provides a stable magnet field, while the latter vibrates to phonate upon applying alternating current or generates alternating voltage in the sound field. This single device exhibits dual functions as a loudspeaker or a microphone. As...
A sensitive and accurate liquid chromatographic method for the determination of AR-42 enantiomeric purity has been developed and validated. Baseline separation with a resolution higher than 1.9 was accomplished within 10 min using a CHIRALPAK AD column (250 mm × 4.6 mm; particle size 5 μm) and n-hexane/2-propanol/diethylamine (75:25:0.1 v/v/v) as mobile phase at a flow rate of 1 mL min−1. Eluted analytes...
Systematic researched have been made of the grain growth and density of sintered ZnO-based systems containing one or more additive oxides of the type Bi2O3, MnO2, and CoO. These samples were characterized using such techniques as scanning electron microscopy. The influence of the nature and amount of additive oxides and sintering temperature at 950 to 1350 °C is discussed in relation to microstructure,...

This paper begins with the elaboration of the legal content and the distinction between “Marine Natural Reserves” (MNRs) and “Marine Special Protected Areas” (MSPAs). Through analyzing the location of National MNR of Xiamen's Rare Marine Species and the Xiamen Island, this paper intends to prove the existence of serious space conflict between the establishment of protected area and the economic development...
In the 12th National Five-year Plan period, China will enhance its industrial competitiveness by leaps and bounds. With the perfection of national policies in Energy Management Contract, the energy-saving industry is offering new opportunities for China to enhance its industrial competitiveness. Based on the Porter Diamond Model, this paper explored the mechanism of Energy Management Contract combined...
