Synthetic Control of Water‐Stable Hybrid Perovskitoid Semiconductors

open access: yesAdvanced Materials, EarlyView.
Hybrid metal‐halide perovskites are promising semiconductors for optoelectronics, yet their water stability is problematic. A new synthesis method is developed using lead iodide and cysteamine under various pH conditions, forming stable perovskitoid structures.

Ferrocene and Ferrocenium Modified Clays and Their Styrene and EVA Composites [PDF]

open access: yes, 2007
In this work, ferrocene- and ferrocenium-containing salts were employed to modify montmorillonite. X-ray measurements show an increase in the interlayer spacing upon clay modification, which means that the larger and more organophilic cations were ...
