This study developed heterogeneous catalysts composed of ZnO and CeO supported on H-ZSM-5 for the direct conversion of methane (CH) and carbon dioxide (CO) into acetic acid. The acid-base and electronic properties were modulated through oxide impregnation and reduction, aiming to create active sites capable of simultaneously activating both reactants. The samples were characterized by XRD, N physisorption, HRTEM/EDS, NH-TPD, CO-TPD, TPR, FTIR, XPS, CO-DRIFTS, and TGA, and tested in a batch reactor at 300 °C and 10 bar.

Reliably defining the risk of adverse in-flight events in aeromedical trauma patients could enable more informed pre-departure treatment and guide central asset allocation to achieve better system-level outcomes. Unfortunately, the current literature base specifically examining the in-flight period is sparse. Flight duration is often considered a proxy for the risk of in-flight deterioration; however, there is limited data to support this commonly held assumption.

Nucleic acid aptamers are artificial recognition elements with great potential in biotechnology. For their effective integration into nanodevices, rational strategies for optimizing aptamer affinity and regulating activity are essential. Artificial nucleotide analogs offer versatile tools for both fundamental and applied research in the aptamer field.

Aim: To understand communication about sexuality for adolescents with cerebral palsy (CP) and complex communication needs.
Method: We systematically searched primary research on adolescents aged 10 to 24 years with CP and/or complex communication needs. We coded the primary evidence against themes derived from a theoretical framework analysis.
