If renewable power sources such as solar and wind could be used to produce chemical precursors and/or fuels, it would provide an alternative to mankind’s currently unsustainable use of fossil fuels and slow the rate of CO2 emission into the atmosphere [1,2]. Solar to chemical energy conversion by electrochemical and photoelectrochemical processes is a potentially promising approach to address this fundamental and important challenge.

Transition-metal dichalcogenide (TMD) monolayers represent an important family of two-dimensional (2D) materials that have drawn tremendous research attention in recent years. They possess many interesting properties and hold potentials of future device applications. Currently, the majority of research works on TMDs are based on exfoliated or chemical vapor deposited samples. In this talk, I shall describe our efforts and progress in growing TMDs by molecular beam epitaxy (MBE) [1].

We discuss new and ongoing work that provides a unified theoretical description for mixtures of charged and polar fluids as well as apolar Lennard-Jones (LJ) mixtures. Our initial focus is on the special case of a two component WA solution where the solute component (A) may be charged or hydrophobic and is very dilute and the solvent W is water as described by the classical SPC/E water model. There can be very interesting behavior of the AA pair correlation function from solvent (W) induced effective interactions that presents difficult problems for both simulations and theory.

Hot gas plays a vital role in shaping galaxy formation and evolution. However, even though we live in a disk galaxy, we know very little about the distribution of this hot gas, and how it impacts the disk galaxy evolution via the so-called “circumgalactic medium”. In this talk, I will discuss several outstanding questions in this field, including problems such as the “missing galactic baryons” and “missing stellar feedback”.
