Feature of our PRL on smectic shells in Soft Matter World

Our article on the nematic-smectic phase transition in microfluidics-produced liquid crystal shells, published recently in Physical Review Letters, Nematic-smectic transition under confinement in liquid crystalline colloidal shells [Hsin-Ling Liang, Stefan Schymura, Per Rudquist and Jan Lagerwall Phys. Rev. Lett., 106, 24, 247801 (2011)], was highlighted in the December 2011 newsletter of Soft Matter World.

New article on liquid crystal shells and electrospun fibers

Web-flash-bild
Our new paper on liquid crystalline shells stabilized by the polymeric surfactant F127 undergoing a nematic-smectic phase transition, and on SEM characterization of electrospun liquid crystal-containing microfibers is finally published as part of the proceedings of last year’s Italian Liquid Crystal conference proceedings. The article follows on Jan’s invited talk at the conference. It is a collaboration with the LC Nano lab at the GSCST.

Bilateral collaboration with Stockholm University on Nanocellulose

SU+SNU_collaboration
Based on a bilateral collaboration grant from NRF (Korea) and STINT (Sweden), the SNM lab will engage in a joint project together with the group of Prof. Lennart Bergström, Stockholm University, Sweden, entitled “New Functional Materials Formed by Self-Assembly of Nano-Cellulose”. The prime aim of the project, starting in the end of 2011, is to develop new and technologically attractive methods of using cellulose, the most abundant material on earth, as a low-cost renewable resource for novel nanostructured functional composite materials.
