Photoswitches are widely investigated molecules because upon exposure to selected light irradiation, they are able to undergo structural, and hence optical, changes. To fully exploit their responsiveness to irradiation, the quantum efficiency of the forward and back reactions is a fundamental parameter, whose accurate determination is critical. In this work, the spectral evolution of a biomimetic switch, which undergoes / photoinduced isomerization, is spectrophotometrically examined.

Article Synopsis
  • Cerate nanoceramics are gaining attention for their potential in improving heat management and solar reflectance.
  • This study uses advanced calculations to show that LaCeO and AlCeO materials have excellent temperature stability, UV-vis/near-infrared reflectance, and customizable mid-infrared emissivity.
  • It also explores how defects and aluminum impurities in the materials can create unique environments for better infrared emission, which is useful for passive cooling technologies.

Oleogels containing silica-silver-based nanomaterials were prepared to be used as potential antimicrobial treatment for preventing and curing skin infections. Fumed silica was used as a bifunctional excipient able to offer support to silver-based nanoparticle growth and act as a gelling agent for oleogel formulation. First, silica-silver composites were prepared following a sustainable method by contact of fumed silica and silver nitrate in the presence of ethanol and successive UV irradiation.

Article Synopsis
  • Recent advancements in electrocatalytic oxygen evolution reaction (OER) show that earth-abundant catalysts still lack optimal efficiency due to complexities in the catalytic system.
  • The study focuses on the impact of the tunable 3D configuration of metal centers, specifically in one-dimensional coordination polymers made of metals like Fe, Co, and Ni, which helps clarify their catalytic performance.
  • Findings reveal that electronic structure, including metal spin and oxidation state, significantly affect ligand binding and can potentially reduce overpotential in OER, aiding in the design of more effective catalysts.

In the framework of intense research about high-entropy materials and their applications in energy-oriented technologies, in the present work, we discuss the potential applicability of selected oxides and of the alloys they form at different concentrations for daytime radiative cooling implementation. In particular, by combining density functional theory and the finite difference method, we provide an unbiased, scattering-free description of structural, electronic, and dynamic features of the best candidates, showing the required strong radiative properties for passive cooling while offering the benefits of affordability and compatibility with commercial coating fabrication processes.
