      Elineema, Gideon; Kim, Jong Kil; Hilonga, Askwar; Shao, Godlisten Namwel; Kim, You-Na; Quang, Dang Viet; Sarawade, Pradip B.; Kim, Hee Taik (Elsevier, 2013-01-25)
      This study reports on the quantitative recovery of high purity nanoporous silica from wastes material (H2SiF6) of the phosphate fertilizer industry and Na2O·SiO2. The silica recovered from the wastes was compared with ...
    • Synthesis and characterization of micrometer-sized silica aerogel nanoporous beads 

      Sarawade, Pradip B.; Quang, Dang Viet; Hilonga, Askwar; Jeon, Sun Jeong; Kim, Hee Taik (Elsevier, 2012-08-15)
      Here we report the preparation of micrometer-sized highly nanoporous, relatively trasperant silica aerogel beads with high surface area as well as large pore volume with sizes ranging from 165 to 395 μm. The wet micrometer-sized ...
    • Synthesis of mesoporous silica with superior properties suitable for green tire 

      Hilonga, Askwar; Kim, Jong-Kil; Sarawade, Pradip B.; Quang, Dang Viet; Shao, Godlisten N.; Elineema, Gideon; Kim, Hee Taik (Elsevier, 2012-09-25)
      In this article we report synthesis of mesoporous silica with superior properties for application in green tire (environmentally friendly tire) as filler. The synthesis was done using a newly innovated apparatus which ...
