We uncovered how the ligand length of the spacer molecules and the metal-halide chemistry influence the in-plane elastic properties of 2D perovskites. We also demonstrated that, unlike conventional inorganic 2D materials, 2D perovskites show a weak mechanical anisotropy in-plane vs. out-of-plane, that can be tuned over a wide range through the composition chemistry.

We propose an efficient and clean avenue for ammonia synthesis, via electroreduction of nitrate which could be obtained from industrial wastewater, domestic sewage, sodium nitrate ore, and nitrification of bacteria and electrochemical oxidation of nitrogen, which addresses the water pollution issues and simultaneously upgrades the nitrate to high-value ammonia. The ammonia formation rate achieved by the copper nanosheets here is more than two orders of magnitude higher than electrochemical nitrogen reduction reaction to ammonia.

We developed multiscale and structured silicon (Si) materials as nongenetic optical transducers capable of modulating the activities of both single bacterial cells and biofilms at high spatiotemporal resolution. We captured a new form of rapid, photothermal dependent, intercellular calcium signaling within the biofilm. We also found an unexpected coupling between calcium dynamics and biofilm mechanics, which could be of importance for biofilm resistance.

Kanatzidis*, Ethylenediammonium Based “Hollow” Pb/Sn Perovskites with Ideal Bandgap Yield Solar Cells with Higher Efficiency and Stability”, Journal of the American Chemical Society, 2019, 141(21), 8627 – 8637. Here we demonstrate the application of a mixed Pb/Sn-based perovskite with oversized ethylenediammonium dications for stable, high performance and environmentally friendly solar cell application. The resulted Pb/Sn film features massive Pb/Sn vacancies, reducing the amount of toxic Pb used in the film and lowering band gap than pure Pb-based perovskites (thus wider absorption range of the solar spectra). The solar cell operation stability is also significantly improved.

A comprehensive characterization of the structure and physical properties of homologous crystals of these new 2D RP perovskites is reported, which are compared to the results from butylamine analogs.

This paper reports that uniaxial strain could induce enlarge the band gap of high n-number 2D HOIPs (n>3), but not low in low n number cases. The strain-induced band gap change is reversible and mainly due to the bond strength and bond angle change in the inorganic Pb-I framework in the 2D HOIPs.
