Transparent Anti-Icing Moiré-Film Enhancing Photovoltaic Stability in Extreme Cold Climates.

Accelerated degradation and power loss of solar cells in cold climates remain major challenges to renewable energy deployment. The photothermal film offers a promising solution by converting sunlight into heat to remove ice and snow from solar panels. However, enhancing photothermal performance often entails reduced visible (VIS) light transmittance of films, thereby compromising solar cell efficiency.

Synthesis optimization of AAR antagonists: shortening the route to accelerate discovery.

Adenosine A receptor (AAR) antagonists have emerged as promising candidates for cancer immunotherapy. In our previous work, we developed benzo[4, 5]imidazo[1, 2‑a]pyrazin-1-amine-3-amide derivatives, including compound 12o, which demonstrated promising pharmacodynamic properties but suffered from poor metabolic stability, with a microsomal half-life of approximately 30 min. To enable structural optimization of 12o and improve lead compound identification, we sought to streamline its lengthy 10-step synthetic route, which had hindered further analog development.

Thermochromic Ni(II) Organometallics With High Optical Transparency and Low Phase-Transition Temperature for Energy-Saving Smart Windows.

Thermochromic smart windows with rational modulation in indoor temperature and brightness draw considerable interest in reducing building energy consumption, which remains a huge challenge to meet the comfortable responsive temperature and the wide transmittance modulation range from visible to near-infrared (NIR) light for their practical application. Herein, a novel thermochromic Ni(II) organometallic of [(C H ) NH ] NiCl for smart windows is rationally designed and synthesized via an inexpensive mechanochemistry method, which processes a low phase-transition temperature of 46.3 °C for the reversible color evolution from transparent to blue with a tunable visible transmittance from 90.

High Near-Infrared Reflective ZnAWO Pigments with Various Hues Facilely Fabricated by Tuning Doped Transition Metal Ions (A = Co, Mn, and Fe).

A series of novel transition metal ion-substituted ZnAWO (A = Co, Mn, and Fe, 0 < ≤ 0.1) inorganic pigments with blue, yellow, brown, and pale green colors have been prepared by a solution combustion method and exhibit extremely high near-infrared reflectance ( > 85%). X-ray energy-dispersive spectroscopy analysis makes it clear that transition metal ions have already been incorporated into the host ZnWO lattice and do not change the lattice's initial wolframite structure.
