Our paper on graphenes entitled "Hierarchical Spatial Heterogeneity in Liquid Crystals Composed of Graphene Oxides" just got published in Physical Chemistry Chemical Physics (PCCP) journal (Impact factor: 4.449). The paper is a collaborative work with Prof. Keiji Tanaka of Kyushu University, Japan and Prof. Sang Ouk Kim of KAIST, South Korea. - 07-20-2016 -
Abstract. Graphene oxide (GO) is a class of two-dimensional materials with a thickness of about 1 nm and a broad distribution of lateral dimension commonly approaching several micrometers. A dispersion of GOs in water often forms a liquid crystal, which is expected to be a promising precursor for the fabrication of carbon-based materials with well-ordered structures. To accelerate the application of GO-based liquid crystals, their structures and physical properties at various sizes must be well understood. To that end, we examined the local rheological properties of GO-based liquid crystals in the nematic phase by a particle tracking technique, where local properties can be accessed by observing the thermal motion of embedded probe particles. Particle diffusion was spatially heterogeneous, and depended on the size of the particles. Such size-dependent heterogeneity can be associated with a hierarchical local environment, which is time-dependent for this system. The anisotropic diffusion of particles originated from particles trapped in between the GO layers and in isotropic-like regions. The aggregation states of the GO dispersion composed of nematic and isotropic-like regions were observed by confocal laser scanning microscopy.
DPenaloza and his PhD Advisor, University of Connecticut (UCONN) Prof. Thomas AP Seery, shared their expertise on a short course on polymeric and colloidal materials held last June 16, 2016 at DE LA SALLE UNIVERSITY, Manila. This was attended by 120+ participants from the industry, government research agencies and the academe. The short course was co-organized by the DLSU Chemistry Department and the D&L Industries, Inc.
