    Abstract: The present invention provides a neutron generating device for generating a high neutron flux by forming plasma in the vicinity of a target and by accelerating electrons and charged particles in the plasma toward the target. Magnetic field is formed in the vicinity of the target and a microwave generator irradiates microwaves into the space where the magnetic field is generated to thereby generate plasma in the space. The accelerated electrons and charged particles collide with the target to generate neutron flux. Also, to prevent the target surface from being excessively heated, the plasma is generated in a pulsed mode and target voltage is applied in a pulsed mode. To secure a continuous process, the level of target bias voltage for the target is adjusted so that the target re-adsorbs elements when the elements adsorbed on the target are depleted.

    Abstract: A method for preparing hydrophobic gold nanoparticles includes adding 1,2-dichlorobenzene as a solvent to gold precursor and using oleylamine and oleic acid with volume ratio of 7.5:2.5 to 5:5 as surfactants. The size of the prepared gold nanoparticles can be controlled over a broad range and may be utilized in various fields such as bio-imaging, photonic crystallization, sensors, organic catalysts, surface enhanced raman spectrum, electronic devices, etc. Further, a method for colorimetric detection of a strong acid uses hydrophilic nanoparticles that are phase transited from the prepared hydrophobic gold nanoparticles. Up to 5 ppm of low content hydrochloric acid can be detected utilizing phase transited hydrophilic nanoparticles in the colorimetric detection method, and the gold nanoparticles that were used in the detection of strong acid can be reused without loss of activity through neutralization with bases.
