Multicomponent photonic glasses and fibers
Shifeng Zhou, South China University of Technology, Guangzhou, Guangdong, China
Multicomponent glasses and fibers are considered to be the fundamental building blocks of the next-generation fiber photonics. In this talk, the recent progress in designs, fabrications and applications of selected materials for multicomponent optical glasses and fibers is introduced. In the first part of the talk, the typical microstructures represented by topological features, heterogeneities and locally crystallized domains are discussed. The preliminary results about the relation between the glass microstructure and its optical properties are introduced. In the second part, glasses and glass-ceramics with various optical functions, including photons generation, manipulation and detection are highlighted.

Toward intrinsic damage resistance and ductility in oxide glasses
Morten M. Smedskjaer, Aalborg University, Aalborg, Denmark
Oxide glasses are among the most important engineering and functional material families owing to their unique features, such as tailorable physical properties. However, at the same time their brittleness has been their main drawback, which severely restricts many applications. Despite much progress, a breakthrough in developing oxide glasses with intrinsic damage resistance and ductility still needs to be made. In this talk, we discuss recent advances and challenges in designing new damage resistant, and potentially tough, oxide glass compositions.

Metal-organic framework liquids, glasses and blends
Thomas Bennett, Cambridge University, Cambridge, UK
Crystalline solids dominate the field of metal−organic frameworks (MOFs), which are highly porous materials formed from the linking of metal nodes with organic linkers. In this family, which number of 70,000 structures, access to the liquid and glass states of matter are usually prohibited by relatively low temperatures of thermal decomposition. Recently, the group has demonstrated the melting three dimensional MOFs belonging to the zeolitic imidazolate framework (ZIF) family, of chemical composition Zn(Im)2 (Im – C3H3N2]. Cooling of these ZIF liquids yields glasses, which are chemically and structurally distinct from existing categories of melt-quenched glasses, and retain the basic metal–ligand connectivity of their parent crystalline frameworks. They possess continuous random networks, and may be thought of, using the data currently available to us, as hybrid equivalents of silica glass.
These new families of metal-organic framework materials, called MOF-glasses and MOF-liquids, provide new opportunities to combine glass science with MOF chemistry. Examples of this, including the mixing together to MOF liquids to form MOF-blends, crystal-glass MOF composites and flux melted glasses are presented here.
Michael Cable Memorial Lecture
You ought to go away and think again!
Richard Hulme, Guardian Industries Corp, USA
Glass making is not a complicated affair but the science underlying the processes involved can be extremely complex. Michael Cable has written extensively about the history and development of glassmaking and throughput his career he pioneered research into some of the fundamental principles which are currently taken for granted, have been forgotten or are ignored at our peril. This presentation will cover some of the things I learned from one of the most eminent glass technologists and why we should continue to reflect on and acknowledge his contributions to our field of work.
