Environmental Impacts and Cost Analysis of Perovskite Nanocrystals for Light‐Emitting Diode Applications

Advanced Sustainable Systems, Volume 9, Issue 9, September 2025.
CsPbBr₃ colloidal nanocrystals synthesized via hot‐injection (HI) and microwave‐assisted (MW) methods exhibit excellent optoelectronic properties for LEDs. Although the MW route is more energy‐efficient and eco‐friendly in the lab, industrially, its environmental impacts are similar, but with lower costs.

The Use of Ornamental Stone Waste (OSW) as Raw Material for Porcelain Ceramic Tiles Production

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
ABSTRACT Despite the relevant contribution of the ornamental stone industry to the international economy, the large volume of waste generated during the production process is one of the main problems faced by the sector. Currently, the ceramic industry has shown to be a powerful alternative for the use of these wastes.

It is cool to be clear: Transparency induces a thermal cost in clearwing butterflies

Functional Ecology, Volume 39, Issue 9, Page 2452-2464, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In butterflies, wing transparency raises the question of potential costs for vital functions, such as thermoregulation. The thermal melanism hypothesis posits that darker colorations enable higher absorption of solar radiation, leading to the prediction that such ...

Above‐ground competition by Nephrolepis brownii inhibits tree seedling recruitment in a tropical restoration experiment

Journal of Applied Ecology, Volume 62, Issue 8, Page 1968-1979, August 2025.
As Nephrolepis brownii primarily interferes through above‐ground competition, management of above‐ground tissues may mitigate its impact. However, additional research on the efficacy of this management strategy and potential allelopathic traits is needed.
