Summary: Hybrid electrochromic devices combine the advantages of solid-state and liquid-based devices to optimize their performances. In this study, a new redox shuttle, thiolate/disulphide, was combined with a transparent thermally curable vinyl-acetate polymer to create a solid-state electrochromic (EC) device. Compared to a device based on I-/I3-, the EC device based on T-/T2 showed higher transparency and coloration efficiency in the visible region of the solar spectrum. Additionally, it displayed a slower self-bleaching process and only lost 30% of its coloration after 1 hour at open circuit, making it highly suitable for smart windows applications that require energy-saving.

Summary: In this study, strong light-matter interaction enhancement and large exciton-polariton nonlinearities at room temperature were demonstrated by combining a tungsten disulfide monolayer and a topologically protected bound state in the continuum formed by a one-dimensional photonic crystal. By optimizing for the electric-field strength at the monolayer position through Bloch surface wave confinement, a 100 meV photonic bandgap with the bound state in the continuum and a Rabi splitting of 70 meV were achieved in a fully open architecture. This architecture opens up possibilities for polariton devices based on topologically protected and highly interacting bound states in the continuum.

Summary: The construction industry demand has significantly increased, leading to higher energy consumption, especially in areas with severe climate conditions. Designers are using software tools to find optimal solutions in the early stages of design to minimize time and cost losses. Smart technologies like electrochromic (EC) glazing can reduce energy consumption while maintaining comfort conditions. However, careful management is required to avoid adverse effects or poor performance. A parametric simulation using Rhinoceros and Grasshopper was conducted to evaluate the energy-saving benefits of using EC glazing in residential buildings in Biskra, Algeria, considering facade orientation and window-to-wall ratio. The research results showed significant energy savings across all orientations.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
