      Ni Ni Than; Fotso, Serge; Sevvana, Madhumati; Sheldrick, George M. (2005)
      The whole plant of Elephantopus scaber afforded the known deoxyelephantopin and isodeoxy-elephantopin, and a new germacranolide sesquiterpene lactone named scabertopin, whose structure and stereo-chemistry were determined ...
    • Some Applications of Alumina Nanoparticles from Coal Fly Ash 

      Myat Myat Thaw; Khine Thin Thin Aye (The Myanmar Academy of Arts and Science, 2016)
      In the present research, coal fly ash samples were collected in Tigypt coal-fired Power Plant from Southwest Shan State in Myanmar. Alumina nanoparticles was synthesized from coal fly ash by using alkali lime sintering ...

      In this research, some physicochemical properties and lead (Pb), mercury (Hg) and cadmium (Cd) concentrations of the thirty-two sea water samples from Tanintharyi coastal zone in Myanmar were determined and compared with ...
    • Structural and electrical characterization of La0.72Ca0.28MnO3 ceramic and thin films 

      Ma, Ji; Mya Theingi; Zhang, Hui; Ding, Xuan; Chen, Qingming (2012)
      La1−xCaxMnO3 bulk ceramic with Ca content of 0.28 was sintered from nano-powders synthesized by sol–gel method. Epitaxial thin films of La0.72Ca0.28MnO3 have been prepared on both untilted and 15° vicinal cut LaAlO3 (0 0 ...
    • Studies on an Unknown Compound from Argyreia barbigera Choisy 

      Htay Htay Win (Universities Research Journal (URJ), 2008)
      Argyrelil barblgera Choisy (Min-go-ga in Myanmar) is widely distributed in Myanmar. The rhizome of Min-go-ga is used as amernorrhoea, diuretic, elephantiasis, paralysis, laxative, arthritis, pneumonia and gonorrhoea. An ...
    • Study of Structural and Electrical Transport Properties of Polycrystalline La1-xCaxMnO3 (x=0.33, 0.5 and 0.9) Prepared by a Co- precipitation Method 

      Mya Theingi; Ma, Ji; Zhang, Hui; Xiang, Gao; Yi, Jianhong; Chen, Qingming (2013)
      Manganite perovskite La1-xCaxMnO3 (x=0.33, 0.5 and 0.9) have been prepared by chemical co-precipitation method. Ammonium carbonate was used to coprecipitate lanthanum, calcium and manganese ions as carbonates under basic ...
