- Our article on the Co nanoparticle-embedded carbon nanofiber for Li oxygen battery was selected as a Wiley-VCH Hot Topic. http://www.wiley-vch.de/util/hottopics/batteries/
- Our article on the Co nanoparticle-embedded carbon nanofiber for Li oxygen battery was selected as a frontcover of ChemSusChem (2015. 7. 31)
Invited for this month’s cover is the group of Jung-Ki Park and Hee-Tak Kim at Korea Advanced Institute of Science and
Technology. The image shows cobalt nanoparticles embedded in carbon nanofibers for use in lithium oxygen (Li–O2) battery:
the fibers attract oxygen molecules and lithium ions due to a charge transfer from cobalt nanoparticles to carbon, inducing
the formation of amorphous lithium peroxide.

- Our article on the interfacial interlocking interface structure of PEMFC was selected as a backcover of Advanced Materials (2015. 5. 20)
A new solution for enhancing interfacial adhesion between the hydrocarbon (HC) membrane and a perfluorinated catalyst layer (CL) in polymer electrolyte fuel cells (PEMFCs) is successfully demonstrated by J.-K. Park, H.-T. Kim, and co-workers on page 2974. This is realized by the intrusion of micrometer-sized pillars fabricated on the HC membrane into the perfluorinated CL, forming an interlocking interface, like Lego blocks. Owing to a higher expansion with hydration for the HC membrane than for the perfluorinated CL, a strong normal force occurs at the interface of the pillars and the holes, resulting in an eight-fold increase of the interfacial bonding strength.
