The purpose of this review is to present an overview of the patent landscape for catalysts used in hydrogenation reactions. Based on patent data extracted from PatBase®, we use predefined patent classifications as well as a keyword‐based search for our analyses. The results indicate that the number of patent families that protect heterogeneous catalysts grows twice as fast as that for their homogeneous counterparts. Furthermore, the data show a shift towards abundant and non‐toxic elements in heterogeneous catalysis, while the noble metals continue to dominate the patent landscape of homogeneous catalysis. A subsequent geographical analysis reveals that the high growth rates in heterogeneous catalysis, especially for nickel and iron, are driven by China. Conversely, patenting activities with regard to homogeneous catalysts mainly take place in the USA, the EU, and Japan. The subsequent keyword‐based search illustrates the continuous industrial relevance of enantioselective hydrogenation and transfer hydrogenation, as well as the rapidly increasing body of patents in hydrodeoxygenation. Setting these finding into context, we present and apply two concepts that are commonly used in patent analyses, namely the technology life cycle and the S‐curve. We conclude that hydrogenation catalysis has not reached its peak economic relevance yet and will continue to spark valuable patents and innovations in the future.
Information technology (IT) has been acknowledged as a driver of innovation performance and scholars agree that the impact of IT is mediated by additional organisational factors. Among those mediators between IT and innovation performance, a firm’s absorptive capacity and developmental culture received considerable attention. Empirical evidence suggests that both fully mediate the impact of IT on innovation performance; however, research that jointly considers both dimensions is scarce. Thus, we follow the resource-based view to operationalise IT assets, absorptive capacity, and developmental culture in one research model and apply SEM to test it with a sample of 58 firms from the water industry in Germany. We find simultaneous full mediation effects for both mediators. The fact that both mediation effects are significant in the presence of each other indicates that absorptive capacity and developmental culture explain complementary portions of the variance in innovation performance — a finding we relate to sociomateriality theory.
The first combination of electrochemistry (EC), NACE, and ESI-MS to mimic the metabolic fate of drugs is described. While the combination of EC, HPLC, and ESI-MS has been used for this purpose before, NACE is able to deliver valuable additional information about possible metabolites of harmane when compared to HPLC. In this paper, NACE is used as a comprehensive separation technique in metabolism studies of harmane, a naturally occurring monoaminooxidase inhibitor, since it exhibits beneficial properties for the separation of polar compounds. Harmane is known to be metabolized via the oxidative metabolism catalyzed by cytochrome P450 enzymes, which are the most important metabolizing superfamily of enzymes in the human liver. The application of HPLC and NACE enabled the detection of 37 products in total, with 14 different mass-to-charge ratios. A total of 31 products could be detected in HPLC-MS and 26 in NACE-MS analysis. The combination of both NACE and RP-HPLC allows the identification of significantly more potential metabolites than any of the separation techniques alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
