The solubilities of different multicomponent lanthanide oxide (Ln<sub>2</sub>O<sub>3</sub>) solid solutions including binary (Ln<sub>1</sub> and Ln<sub>2</sub> = La, Nd, Eu, or Tm), ternary (Ln<sub>1</sub>, Ln<sub>2</sub>, and Ln<sub>3</sub> = La, Nd, Eu, or Tm), and higher systems (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) were studied after aging for four weeks at 60℃. Our recent study revealed that the phase transformations in binary ((La, Nd) and (La, Eu)) and ternary (La, Nd, Eu) systems are responsible for the formation of (La, Nd)(OH)<sub>3</sub>, (La, Eu)(OH)<sub>3</sub>, and (La, Nd, Eu)(OH)<sub>3</sub> solid solutions, respectively. The variations in the mole fractions of La<sup>3+</sup>, Nd<sup>3+</sup>, and Eu<sup>3+</sup> in the sample solutions of these hydroxide solid solutions indicated that a thermodynamic equilibrium might account for the apparent La, Nd, and Eu solubilities. Conversely, the binary and ternary systems containing Tm<sub>2</sub>O<sub>3</sub> as the heavy lanthanide oxide retained the oxide-based solid solutions, and their solubility behaviors were dominated by their congruent dissolutions. In the higher multicomponent system, the X-ray diffraction patterns of the solid phases, before and after contact with the aqueous phase indicated the formation of a stable oxide solid solution and their solubility behavior was explained by its congruent dissolution.

Little progress has been achieved relating to the preparation of shapespecific carbon quantum dots (CQDs) with a well-ordered edge structure and multi-color fluorescence from a single precursor by monitoring and controlling the reaction time. Selecting phloroglucinol as a precursor of CQDs is useful for monitoring the shape and structure of CQDs during dehydration mediated controlled growth, which assists to better focus on their formation and PL emission mechanism. We report the rapid synthesis of novel shape-specific CQDs with multicolor fluorescence emission by controlling the reaction time. Furthermore, the multi-color fluorescence CQDs are successfully used as propitious fluorescent probes for multi-color cell (HeLa) and zebra fish imaging owing to an effective intracellular distribution and good biocompatibility.

A feeding trial was conducted to evaluate the effects of two different sizes of extruded pellets (EP) (EP1 - 3 mm or EP2 - 5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared in semi-recirculation system. A total of 450 fish with an average initial weight of 5.0 ± 0.2 g (mean ± SD) were fed one of the three experimental diets in triplicate groups. At the end of a 6-week feeding trial, weight gain, specific growth rate, and feed efficiency of fish fed EP diets were significantly higher than those of fish fed MP (P < 0.05). Water quality parameters like turbidity, total ammonia nitrogen, and total phosphorous from tanks of fish fed EP1 and EP2 were significantly lower than those from tanks of fish fed MP. Blood plasma glutamic oxaloacetic transaminase and glucose concentration were significantly higher in fish fed MP diet compared to fish fed EP diets (P < 0.05). Whole body crude protein contents in fish fed EP diets were higher than those from the fish fed MP diet. Whole body amino acid content like threonine, aspartic acid, serine, tyrosine, and cystine were found to be significantly higher in fish fed EP diets than those in fish fed MP diet. In considering overall performance of olive flounder, EP2 diet could be recommended for the successful aquaculture of this important fish species.
