Article Abstract
Photochromic smart windows with efficient solar heat and sunlight modulation are highly sought after for energy efficiency in buildings. However, the preparation of organic-inorganic hybrid photochromic coating with high transparency and excellent dimming ability remains a challenge. Here, we achieve a high dispersion of inorganic nanoparticles in the polymer network based on the B─O─W coordination bond locking strategy, and effectively reduce the energy band gap of Phosphotungstic acid (PTA) by adjusting the local coordination and electronic environment of the metal centre (W) to design a novel conjugated organic-inorganic hybrid photochromic material with high transparency (96.4%), rapid photoresponse (colouring in10 s), and excellent dimming ability (reaching saturation state in 20 min, Visible light modulation range △T = 87.1%, △T = 94.0%). Selective heating and cooling of interiors in winter and summer shows excellent potential for improving indoor sunlight comfort and increasing energy efficiency in buildings.

Two diketopyrrolopyrrole (DPP)-based dichroic dyes were synthesized and investigated for application in dye-doped liquid crystal (LC) smart windows. These dyes exhibited strong absorption in the long-wavelength region, particularly DPP-2, addressing the limited absorption of benzothiadiazole (BT)-based dyes beyond 650 nm. Both DPP dyes demonstrated high dichroic ratios and excellent alignment within the LC host, enabling effective transmittance modulation under an electric field.

Polymer-stabilized liquid crystal (PSLC) dimming film has attracted widespread attention due to its normally transparent state, energy-saving capability, and excellent electro-optical performance, which has promising applications in smart cars and building windows. However, achieving good electro-optical performance and high peel strength simultaneously still remains challenging. In this study, a PSLC film based on monoepoxy and diepoxy monomers was prepared through rapid cationic polymerization, showing low driving voltages and high peel strength simultaneously.

The coronavirus-induced disease 19 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections, has had a devastating impact on millions of lives globally, with severe mortality rates and catastrophic social implications. Developing tools for effective vaccine strategies and platforms is essential for controlling and preventing the recurrence of such pandemics. Moreover, molecular virology tools that facilitate the study of viral pathogens, impact of viral mutations, and interactions with various host proteins are essential.

Background: Indoor lighting, exposure to outdoor daylight, physical activity and sleep interact to influence functioning, mood and cicadian rhythm. Older adults (≥ 65 years), who often spend more time at home, are less physically active and experience more sleep problems, could benefit from strategies to support behavioural change and self-managed modifications in the home. The study's primary objective was to assess the usability and feasibility of the 'Light, activity and sleep in my daily life' intervention, delivered as a web-based course.
