Electrolysis in reduced gravitational environments: current research perspectives and future applications.

Electrochemical energy conversion technologies play a crucial role in space missions, for example, in the Environmental Control and Life Support System (ECLSS) on the International Space Station (ISS). They are also vitally important for future long-term space travel for oxygen, fuel and chemical production, where a re-supply of resources from Earth is not possible. Here, we provide an overview of currently existing electrolytic energy conversion technologies for space applications such as proton exchange membrane (PEM) and alkaline electrolyzer systems.

Azido-functionalized gelatin via direct conversion of lysine amino groups by diazo transfer as a building block for biofunctional hydrogels.

Gelatin is one of the most prominent biopolymers in biomedical material research and development. It is frequently used in hybrid hydrogels, which combine the advantageous properties of bio-based and synthetic polymers. To prevent the biological component from leaching out of the hydrogel, the biomolecules can be equipped with azides.

How Cleveland Clinic used TDABC to improve value.

Cleveland Clinic partnered with Harvard Business School to conduct a pilot project to explore the differences between time-driven activity-based costing (TDABC) and relative value unit costing. The goal was to determine whether TDABC could improve the accuracy of cost information and identify value-improvement opportunities for two types of heart-value procedures. Using TDABC, leaders gained a detailed look into process steps that could be consolidated, reduced, or performed with a lower cost mix of personnel.
