The superior catalytic performance of ZrO₂ in catalytic propane dehydrogenation is attributed to be the unsaturated coordination zirconium (Zr_cus) near the oxygen vacancy. However, the calculations revealed the double-edged role of oxygen vacancy in reaction, which significantly reduced C-H bond activation barrier but hinder the facile desorption of products due to strong binding. Moreover, the localized electron within oxygen vacancy is identified as the driving force for the C-H bond activation. The complete two different mechanisms are also noted for pristine and defective surfaces which also resulted from the double-edges effects of oxygen vacancy.

A new study has revealed the existence of bifunctional diterpene cyclases/synthases (DCSs) in bacteria, offering compelling evidence that the plant terpene synthase gene family, termed TPS, originated from bacterial genes. 

Next-generation high-brightness laser lighting confronts a key challenge in developing static luminescent materials with remarkable optical-thermal performances and low cost. Herein, a unique composite architecture of Y₃Al₅O₁₂:Ce³⁺ (YAG) phosphor-in-glass film coated on different heat-conducting substrates (PiGF@HCSs), i.e., PiGF@sapphire, PiGF@Al₂O₃, PiGF@AlN, and PiGF@BN-AlN composites, was designed and prepared by a simple film printing and low-temperature sintering technology. The heat-conducting substrates significantly affect the luminescence saturation and phosphor conversion of PiGF@HCSs, making the substrates with higher thermal conductivity (TC) can bear higher laser power density (LPD) and higher reflectivity can enable higher luminous efficacy (LE). These findings will provide the guiding idea for the commercial applications of PiGF@HCS converters in high-brightness laser lighting and display.
