Abstract While hyperuniform‐disordered patterns have been researched from a theoretical perspective for two decades, large scale experimental realizations remain scarce. In this work, as a potential route to overcome this issue, 2D patterns are eva

Shape-stabilized phase change materials (ss-PCMs) based on silica and butyl stearate were thermally enhanced via the addition of different hexagonal boron nitride particles (BN) to the in situ sol-gel synthesis. The dataset is used in conjunction wit

A review of recent progress in the field of strained silicon photonics is presented. The application of strain to waveguide and photonic crystal structures can be used to alter the linear and nonlinear optical properties of these devices. Here, metho

We review several examples of how spectrally-selective photonic structures may be used to improve solar cell systems. Firstly, we introduce different spectrally-selective structures that are based on interference effects. Examples shown include Rugat

A major loss mechanism in organic light emitting diodes (OLEDs) is the coupling of the emitter molecule light field to waveguide modes in the OLED thin film stack. In this work, a disordered 2D array of TiO$_{2}$ nanodisk scatterers is integrated int

Glass foams (GF) are materials with a porous framework characterized by pore sizes spanning different orders of magnitude. In this study, we report for the first time the synthesis and characterization of GF with cavities ranging from macro- to mesop
