Summary: Structural color is a non-fading pigment that is obtained from materials with periodic variation of refractive index. It has low environmental impact and toxicity and can cover the full visible spectrum by tuning the size and arrangement of nanoparticles. The optical properties of these pigments are directly related to the arrangement of nanoparticles within the pigment.

Summary: We demonstrate the ability to control both the optical stopband wavelength and effective bandwidth of gel-immobilized loosely packed colloidal photonic crystals. By photopolymerizing the gelation reagent of charge-stabilized colloidal crystals under different upper- and bottom-light intensities, we obtain a gel-immobilized film with broadened Bragg reflection peak. Furthermore, by varying the swelling solvent concentration, we can vary the Bragg wavelength over a wide range while maintaining the same broadened effective bandwidth.

Summary: A two-step spraying process followed by thermal curing has been developed to prepare waterproof PC coatings with bright, uniform, and angular-dependent structural colors. The coatings present colors with high saturation, including red/yellow/green/blue colors achieved by tuning the particle size, and many spectral/non-spectral colors via the mixing of base colors. The coatings offer a new choice for personalized automotive coatings with shiny colors changing with the viewing angles or the surface curvatures.

Summary: This study investigates the phase behaviors of aqueous suspensions using depletion interactions. The concentration of depletant and salt in the suspension is adjusted to produce fluid, crystal, and glass phases. The phase boundary between fluid and crystal is determined by the depth of the energy well, while the onset of glass formation is characterized by the assembly rate. Crystals are formed when enthalpy gain outweighs entropy loss, while glasses are kinetically produced due to fast jamming.

Summary: Organic co-solvents can control crystal morphology and create single–crystal nanocomposites. In this study, different volume ratios of acetonitrile/H2O binary solvent mixtures were used to investigate the phase transformation of calcium carbonate. It was found that calcium carbonate underwent a dissolution recrystallization pathway, or Ostwald ripening process, which was largely dependent on the content of water and dielectric constant. These findings provide an effective strategy for the synthesis of biominerals using organic solvents alone.

Summary: This study reports the use of silk fibroin (SF) as a flexible OLED substrate to improve device performance by enhancing light extraction efficiency (LEE). SF-based flexible OLED outperforms the reference device in terms of turn-on voltage, peak brightness, and LEE. The improved performance can be attributed to the low refractive index of SF, its lower surface roughness, and more matched energy levels compared to other substrates. Additionally, a molecular dipole layer formed between the interface of indium tin oxide (ITO) and SF effectively changes the ITO work function, reducing the potential barrier height for hole transfer.
