Yunnan Normal University is located in Kunming, the capital city of Yunnan Province. Established in 1938 as the National Normal College of Southwestern Union University based on Beijing University, Tsinghua University, and Nankai University, it was named as National Kunming Normal College in 1946 when the faculties returned to the north. Yunnan Normal University is a key university of Yunnan Province, with a long history and a great tradition. It is a higher institution co-funded by the Ministry of Education and the Provincial Government of Yunnan and one of the one hundred universities funded by the National Key Project for the Quality Enhancement of the Higher Institutions in Central and West China.After the Anti-Japanese War broke out in 1937, Peking University, Tsinghua University and Nankai University moved to Kunming and merged into the National Southwest Associated University, which consisted of School of Humanities, School of Science, School of Engineering, School of Business and Law, and the Teachers College. Following the end of the War, the three component universities moved back to their original sites in the north, but the Teachers College, renamed National Kunming Teachers College, stayed behind to become an independent institution. In 1950, the word “National” was dropped from its name. A few decades later, in 1984, it acquired its present name, Yunnan Normal University. In the past 75 years, YNNU has graduated more than 200,000 students for the country and is thus known as the “Cradle of Teachers on the Red-soil Plateau”.YNNU covers a total area of thirty-three hundred and thirty mu . It consists of twenty-six schools and more than forty research centers and institutes.

Hydrogen sulfide (H2S) has long been considered as a phytotoxin but, nowadays, as a novel signaling molecule at low concentration in plants, which is involved in plant growth, development, and the acquisition of tolerance to abiotic and biotic stresses. H2S is commonly found only in very small amounts in most biological systems. To further understand H2S functions, accurate measurement of H2S concentration in plants is very important. In this chapter, quantificational methods of H2S in plant tissues, namely, methylene blue (MB) and 5,5′-dithiobis(2-nitrobenzoic acid) (DTNB) methods, are introduced; the former has higher sensitivity than that of the latter, and the determination limits of MB and DTNB methods are 1.5 × 10- 7 M (0.005 μg/ml) and 3.7 × 10- 6 M (0.13 μg/ml), respectively, hoping to stimulate more research into H2S signal molecule in plants. © 2015 Elsevier Inc.

Knowledge about the importance of fluoride ions in biological and medical processes has grown in recent years. It is now known that this anion plays a role in dental health and has potential use for the treatment of osteoporosis. Fluoride is easily absorbed by the body but is excreted slowly. Fluoride also plays an important role in a number of military applications. For example, the refinement of uranium in nuclear weapons manufacturing utilizes fluoride. GB, more commonly known as sarin (isopropyl methylphosphonofluoridate), is a nerve agent employed by the Aum Shinrikyu cult in terrorist attacks in Tokyo in 1995. Over the past two decades, a large number of optical sensors have been developed for detecting fluoride. For the most part, the methods employed in these sensors rely on strong interactions taking place between Lewis-acidic boron and fluoride, as well as hydrogen bonding and other types of interactions involving fluoride as a participant or a disrupter. In addition, reaction-based chemodosimeters have been devised for the selective detection of fluorides.

The utilization of paraffin in the latent thermal energy storage (LTES) system for solar energy storage is hampered by its low thermal conductivity. Paraffin/nickel foam and paraffin/copper foam composite phase change materials (PCMs) were prepared using a vacuum impregnation method in the present study. The impregnation ratios which reflect the actual mass fraction of pure paraffin impregnated were studied comparatively for the impregnations with and without vacuum assistance. The surface porosity was obtained by employing the image processing approach. The thermal conductivities of the composite PCMs were measured by the transient plane heat source technique (TPS) as well as the steady state method, and the thermal behaviors were analyzed with a differential scanning calorimeter (DSC). It is found that the surface porosity obtained from image analysis was in the range of 90-94%, whereas the bulk porosity predicted by the mass fraction was about 97%. Compared with pure paraffin, the thermal conductivities of the composite PCMs were drastically enhanced, e.g., the thermal conductivity of the paraffin/nickel foam composite was nearly three times larger than that of pure paraffin. The presence of porous metal foam made the phase change temperatures shift slightly, e.g., the deviations of the peak melting temperatures of the paraffin/nickel foam composite and paraffin/copper foam composite with the pore size of 25PPI from those of pure paraffin were 0.55. °C and 0.40. °C, respectively. © 2013 Elsevier Ltd.
