Hydrolysis of regenerated cellulose from ionic liquids and deep eutectic solvent over sulfonated carbon catalysts
Autor: Han Ung Kim, Jong Wha Kim, Sumin Seo, Jungho Jae
Publikováno v: RSC Advances. 13:8153-8162
The pretreatment of cellulose using the dissolution/regeneration process in ionic liquid and deep eutectic solvents leads to substantially higher hydrolysis efficiency than the conventional ball-milling pretreatment.

Hydrolysis of Regenerated Cellulose from Ionic Liquids and Deep Eutectic Solvent over Sulfonated Carbon Catalysts
Autor: Han Ung Kim, Jong Wha Kim, Sumin Seo, Young-Kwon Park, Jungho Jae
The efficient hydrolysis of cellulose into its monomer unit such as glucose or valuable cello-oligosaccharides is the critical step for the cost-effective production of biofuels and biochemicals. However, the current cellulose hydrolysis process invo

Adsorption equilibrium and kinetics of H2O on zeolite 13x
Autor: Seung-Ju Lee, Chang-Ha Leef, Jong Wha Kim, Young Ki Ryu
Publikováno v: Korean Journal of Chemical Engineering. 18:525-530
The adsorption characteristics of H2O on zeolite 13X were measured by a gravimetric method. The adsorption isotherm showed type II isotherm and was fitted by using both the excess surface work (ESW) model and Langmuir-Freundlich model. The results pr

Effect of rapid thermal annealing on the structural and electrical properties of TiO2 thin films prepared by plasma enhanced CVD
Autor: Jong-Wha Kim, Yoon-Bong Hahn, Do-Oh Kim
Publikováno v: Korean Journal of Chemical Engineering. 15:217-222
Titanium oxide thin films were deposited on p-type Si(100), SiO2/Si, and Pt/Si substrates by plasma enhanced chemical vapor deposition using high purity Ti(O-i-C3H7)4 and oxygen. As-deposited amorphous TiO2 thin films were treated by rapid thermal an

Preparation of PbTiO3 thin films by plasma enhanced MOCVD and the effect of rapid thermal annealing
Autor: C. J. Youn, Jong-Wha Kim, Yoon-Bong Hahn, In-Sun Lee
Publikováno v: Journal of Electronic Materials. 26:1394-1400
Dielectric PbTiO3-thin films were prepared on p-Si(100) substrate by plasma enhanced metalorganic chemical vapor deposition using high purity Ti(O-i-C3H7)4, Pb(tmhd)2, and oxygen. As-deposited films were post-treated by rapid thermal annealing method

Preparation and characterization of TiO2 thin films by PECVD on Si substrate
Autor: C. J. Youn, In-Sun Lee, Yoon-Bong Hahn, Jong-Wha Kim, Sangkyu Park
Publikováno v: Korean Journal of Chemical Engineering. 13:473-477
Titanium oxide thin films were prepared on p-Si(l00) substrate by plasma enhanced chemical vapor deposition using high purity titanium isopropoxide and oxygen. The deposition rate was little affected by oxygen flow rate, but significantly affected by
