Tetrahedral Nitrogen Atoms Arrangement in A‐Site Cations: A New Approach for Regulating Sensitivity and Energy of Perovskite Energetic Materials

open access: yesAdvanced Science, EarlyView.
The urotropine is selected as the A‐site cation in PEMs, and four urotropine‐based PEMs ([C6H14N4][M(ClO4)3]) are successfully prepared. Compared with the cubic PEMs, the crystal structure of the urotropine‐based PEMs has an expansion along the c‐axis.

Can soil biology tests improve phosphorus and potassium corn fertilizer recommendations?

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3457-3472, November/December 2022., 2022
Abstract Integrating soil health (SH) biological properties with soil fertility (SF) evaluations offers a unique opportunity to potentially refine fertilizer recommendations. The objectives of this research included: (a) evaluating current University of Missouri P and K fertilizer recommendations for corn (Zea mays L.) and (b) assess whether SH ...
