We report a reversible structural phase transition in a metal–organic framework (MOF) triggered by the exchange of coordinative guest molecules. This MOF consists of rigid 1D Pb–O rods as building units, forming a 3D framework with 1D pores. Guest exchange induces pronounced changes in both the Pb–O rod structure and the dimensionality of the framework.

Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Revisiting the synthesis of dimethyl carbonate from methanol and carbon dioxide
Abstract The process for producing dimethyl carbonate (DMC) from carbon dioxide (CO2) and methanol is explored in this article. It provides an overview of the thermodynamics involved in DMC synthesis, discussing the challenges and potential solutions. The article highlights the reported use of catalysts and dehydrating agents to improve DMC yield and ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.
