BRAIN POTENTIALS OF ONLINE CONTENT EMOTIONALITY ON SOCIAL MEDIA
Yujing Huang,Jia Jin,Hao Ding,Yizhou Shao,Bonai Fan,Qingguo Ma 글로벌지식마케팅경영학회 2018 Global Marketing Conference Vol.2018 No.07
Introduction Current research investigated whether emotionality of content would facilitate the possibility to share information on social media by using event-related potentials. Theoretical development Emotionality is an excitatory state which evokes autonomic nervous system. Previous studies suggested that stimuli with high emotionality elicited increased P100/P200 amplitudes relative to stimuli with low emotionality (Huang & Luo, 2006). Research design We tested the purpose in an affective priming paradigm in which participants were exposed to online content (i.e. the prime stimulus) followed by a stimulus (i.e. the target stimuli) from International Affective Picture System. Participants were required to judge whether the target was neutral white picture. Next, a nine-point Likert scale was followed to assess the level of emotionality for online content. Result and conclusion We observed a congruency effect in the priming effect. More importantly, early brain potentials P100/P200 were higher when participants were exposed to online content with more possibility to share than online content with less possibility to share. This finding could be explained by the response level account theory (Fazio, 2001). This study provides an insight to neural mechanism underlying emotionality of online content.
Solvent extraction of Fe3+ from the hydrochloric acid route phosphoric acid by D2EHPA in kerosene

It is necessary to remove Fe3+ from the hydrochloric acid route phosphoric acid before it is purified by trin-butyl phosphate (TBP), otherwise the final product will fail because of the excessive iron content. Di-(2-ethylhexyl) phosphoric acid (D2EHPA, HA) is effective for Fe3+ extraction. Therefore, the solvent extraction of Fe3+ from the HCl-route phosphoric acid by D2EHPA in kerosene is investigated. The effects of the extraction time, temperature and concentrations of phosphoric acid, D2EHPA, calcium chloride and Fe3+ on the extraction process are studied. The mechanism of the extraction is explained and the extracted species is demonstrated to be FeClA2 4HA. D2EHPA has a high efficiency for Fe3+ extraction from the synthesis and actual HCl-route phosphoric acid with extraction percent of 98.61% and 96.50%, respectively via a cross-current 3-stage extraction. The loaded organic phase is effectively stripped (99.9%) using 6 mol/L hydrochloric acid. The extractant also has a high stability under a closed operation condition. D2EHPA can serve as an adequate extractant for the extraction of Fe3+ from the HCl-route phosphoric acid.
Self-Organized Synthesis and Mechanism of SnO<sub>2</sub>@Carbon Tube-Core Nanowire
Luo, Minting,Ma, Yong-Jun,Pei, Chonghua,Xing, Yujing,Wen, Lixia,Zhang, Li Korean Chemical Society 2012 Bulletin of the Korean Chemical Society Vol.33 No.8
$SnO_2@carbon$ tube-core nanowire was synthesized via a facile self-organized method, which was in situ by one step via Chemical Vapor Deposition. The resulting composite was characterized by scanning electron microscopy, X-ray diffraction and transmission electron microscope. The diameter of the single nanowire is between 5 nm and 60 nm, while the length would be several tens to hundreds of micrometers. Then X-ray diffraction pattern shows that the composition is amorphous carbon and tin dioxide. Transmission electron microscope images indicate that the nanowire consists of two parts, the outer carbon tube and the inner tin dioxide core. Meanwhile, the possible growth mechanism of $SnO_2@carbon$ tube-core nanowire is also discussed.
