Abstract:	The Co-Ni-P nanorods were fabricated by electrodeposition method by using the porous polycarbonate template. The investigation by mean of X-ray diffraction and high-resolution transmission electron microscopy indicated that samples were nanocrystalline clusters embedded in the amorphous base. The samples exhibited a room temperature ferromagnetism with the high magnetic anisotropy along the rod. The applied magnetic fields during the fabrication of the Co-Ni-P nanorods was strongly influenced by the magnetic properties. The MR/MS ratio and coercivity rapidly increased when the magnetic applied field changed from 0 to 0.21 T.

Abstract:	This paper proposes a method based on linguistic word-formation rules and dictionaries for determining reduplicative words in Vietnamese. The key idea for identifying whether adjacent syllables in a text can form a reduplicative word based on its formation rules. For 2-syllable reduplicative words, this paper uses rules that describe the repeating and the opposing between pairs of initial consonants, rhymes and tones. Then the method is expanded to identify reduplicative words that have 3 or 4 syllables from 2-syllable ones for the Vietnamese word segmentation task. Experimental results showed that the F1-score was improved to 98.61% and that word segmentation errors were reduced significantly, 1.26%

Abstract:	In this study, we attempted to enrich neutrophilic iron bacteria in a microbial fuel cell (MFC)-type reactor in order to develop a lithotrophic MFC system that can utilize ferrous iron as an inorganic electron donor and operate at neutral pHs. Electrical currents were steadily generated at an average level of 0.6mA (or 0.024mA cm-2 of membrane area) in reactors initially inoculated with microbial sources and operated with 20mM Fe2+ as the sole electron donor and 10ohm external resistance; whereas in an uninoculated reactor (the control), the average current level only reached 0.2mA (or 0.008mAcm-2 of membrane area). In an inoculated MFC, the generation of electrical currents was correlated with increases in cell density of bacteria in the anode suspension and coupled with the oxidation of ferrous iron. Cultivation-based and denaturing gradient gel electrophoresis analyses both show the dominance of some Pseudomonas species in the anode communities of the MFCs. Fluorescent in-situ hybridization results revealed significant increases of neutrophilic iron-oxidizing bacteria in the anode community of an inoculated MFC. The results, altogether, prove the successful development of a lithotrophic MFC system with iron bacteria enriched at its anode and suggest a chemolithotrophic anode reaction involving some Pseudomonas species as key players in such a system. The system potentially offers unique applications, such as accelerated bioremediation or on-site biodetection of iron and/or manganese in water samples.
