Fluorine-Free Ion-Selective Membrane with Enhanced Mg Transport for Mg-Organic Batteries.

Magnesium batteries offer a safer alternative for next-generation battery technology due to their insusceptibility to dendrite deposition. Selective membranes tailored for magnesium-ion conduction will unlock further technological advancement. Herein, we demonstrate fluorine-free magnesiated sulfonated poly(ether ether ketone) (Mg-SPEEK) selective membranes capable of facilitating magnesium-ion conduction while effectively rejecting soluble organic species.

[Physiological and pathophysiological changes of the ageing lung].

Background: Due to age-related changes the lung function decreases. At the same time there is an increase in pulmonary diseases that lead to restrictions in mobility and autonomy.

Research Question: What are the underlying changes in lung ageing? To what extent do they affect lung function and are there factors that can be influenced?

Method: Literature search.

Effect of Surface Finishing and Nitriding on the Wetting Properties of Hot Forging Tools.

Lubrication is a critical aspect of the metal forming process and it is strongly influenced by the surface texture of the tool-forming surfaces. This study is focused on determining the effect of surface finish and heat treatment on wettability involving commonly used lubrication agents. Three different finishing states are evaluated (as-ground, as-polished and as-nitrided).

[Platelet Concentrates - Indication, Informed Consent, Transfusion and Adverse Events].

Transfusion of platelet concentrates (PC) can be a life-saving measure in case of severe thrombocytopenia or thrombocytopathy, particularly in bleeding patients. Although acaryote, platelets are involved in several important functions including immunomodulation, but their most important function is in primary and secondary haemostasis. In this German review, apheresis and whole blood derived PC are compared and indications as well as transfusion triggers and dosage of PC are discussed.
