Purpose: The main objective of this study was to investigate the effect of stimulus rate and gender on the latency and amplitude of the auditory middle latency response (AMLR) in Korean young females and males. Methods: A total of thirty young subjects consisting of fifteen males and fifteen females participated in the study. The stimulus repetition rate was changed in five steps: 0.5, 1, 2, 4, and 8/s. Results: The results showed significant differences of the stimulus rates on the Na latency,...

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is...

Energy storage devices and renewable energy sources are some of the most interesting alternatives being developed to solve the energy crisis [1,2]. At the same time, energy harvesting and storage devices are among the technologies with the highest potential to efficiently satisfy the energy requirements of compact electronic devices [3]. Among various energy storage devices, supercapacitors are the among the most intensely researched because of their high power density, long cycle retention, and...

Carbon materials with at least one dimension of 1?100 nm are called carbon nanomaterials. A significant body of previous research in physics, chemistry and biology has demonstrated that the properties of nano-composites are significantly different than those of the bulk materials [1]. Some unique phenomena, such as the quantum tunneling effect, and surface effects, have also been observed, and attributed to the large surface area and small size of the carbon nanomaterials. It has been reported...

This paper introduces a nitrogen-doped ordered mesoporous carbon (NOMC) derived from glucosamine with hybrid capacitive behaviors, achieved by successfully combining electrical double-layer capacitance with pseudo-capacitance behaviors. The nitrogen doping content of the fabricated NOMC reached 7.4 at% while its specific surface area (SBET) and total pore volume reached 778 m2 g?1 and 1.17 cm3 g?1, respectively. A dual mesoporous structure with small mesopores centered at 3.6 nm and large...

at a medium carbonization temperature. Therefore, it was possible to control the crystalline structure, SSA, and pore structure of AC by changing the pre-carbonization temperature. Because the electrode density increased with increasing of the pre-carbonization temperature, the highest volumetric capacitance of 28.4 F/cc was obtained from the PP pre-carbonized at 700°C, exhibiting a value over 150% of that of a commercial AC (MSP-20) for EDLC. Electrochemical activation was observed from the...
