E demand on our traditional energy resources makes harnessing underutilized alternative energy sources all the more necessary and desirable to the scientific community. Colloidal copper(I) sulfide nanocrystals (NCs) are an attractive photovoltaic device component due to their solar absorption characteristics; Cu2S is a p-type semiconductor with a bandgap reported from 1.1 to 1.4 eV, and an abso...

Introduction. During the past decade, nanocrystal research has been focused on two major properties of finite size materials, namely, quantum size effects and surface/interface effects.1 A new trend, however, has emerged in the past few years to arrange the nanocrystals into two or three-dimensional superlattices.2 The ability to synthesize nanocrystal superlattice (NCS) structures will provide...

The α-helix – a common building block of the protein secondary structure – plays an important role in determining protein structure and function. The biological function of the α-helix is mainly attributed to its large macrodipole originating from the alignment of individual dipole moments of peptide bonds. Preparation of directionally aligned α-helical peptide layers on substrates has attracte...

It is well established that supercritical fluids such as supercritical CO2 are dense fluids that do not demonstrate the often detrimental surface tensions and interfacial phenomena exhibited by other liquids. Supercritical CO2 has hence become widely used in the microelectromechanical systems (MEMS) industry to dry release devices while avoiding the liquid-vapor interface that can cause the cap...
