Much work has been happening on the boundary of statistical mechanics and combinatorics in recent years, and, in particular, in the area of lattice models and exactly solvable models. In this talk, we focus on the six-vertex model on the square lattice with domain-wall boundary conditions. Configurations of this model on the n-by-n square lattice are known to be counted by a very nice formula; this long-standing combinatorial conjecture was proved using tools from physics. Moreover, these configurations are in bijection with alternating sign matrices, which are simply-described matrices with entries in {0,1,-1}. Alternating sign matrices exhibit many intriguing combinatorial properties and surprising relationships with other physics models, such as loop percolation. We give a survey of the various connections between alternating sign matrices and statistical physics, along with some very recent work and several open problems.

Nanocrystals exhibit a wide range of unique properties (e.g., electrical, optical, and optoelectronic) that depend sensitively on their size and shape, and are of both fundamental and practical interest. Breakthrough strategies that will facilitate the design and synthesis of a large diversity of nanocrystals with different properties and controllable size and shape in a simple and convenient manner are of key importance in revolutionarily advancing the use of nanocrystals for a myriad of applications in lightweight structural materials, optics, electronics, photonics, optoelctronics, magnetic technologies, sensory materials and devices, catalysis, drug delivery, biotechnology, and among other emerging fields. In this talk, I will elaborate a general and robust strategy for crafting a large variety of functional nanocrystals with precisely controlled dimensions (i.e., plain, core/shell, and hollow nanoparticles) by capitalizing on a new class of unimolecular star-like block copolymers as nanoreactors. This strategy is effective and able to produce organic solvent-soluble and water-soluble monodisperse nanoparticles, including metallic, ferroelectric, magnetic, luminescent, semiconductor, and their core/shell nanoparticles, which represent a few examples of the kind of nanoparticles that can be produced using this technique. The applications of these functional nanocrystals in energy-related applications (i.e., solar cells and photocatalysis) will also be discussed.
