Gips – die wundersame Vielfalt schlichten Calciumsulfats
Mit Gips assoziiiert man zunächst wahrscheinlich seine Anwendungen im Baubereich etwa als Gipskartonplatten oder in der Medizin als Gipsbinden bei Knochenbrüchen. Unser Beitrag zeigt eine andere, unerwartet vielfältige Seite des häufig vorkommenden Minerals.
Die riesigen Gips-Kristalle auf unserem Titelbild befinden sich in einer der Höhlen der Mine von Naica im Norden von Mexiko. Die Bedingungen in der erst im Jahr 2000 entdeckten Höhle sind extrem: Die Temperatur beträgt fast 50 °C und die Luftfeuchtigkeit rund 90–100 %.

石膏--简单硫酸钙的奇妙多样性人们可能首先想到的是石膏在建筑领域的应用，例如用作石膏板，或在医学领域用作治疗骨折的石膏绷带。我们的文章展示了这种常见矿物出人意料的另一面：封面图片上的巨大石膏晶体是在墨西哥北部纳伊卡（Naica）矿的一个洞穴中发现的。该洞穴于 2000 年才被发现，洞内条件极端恶劣：温度接近 50 °C，湿度约为 90%-100%。(图片：Alexander Van Driessche - CC BY 3.0, https://commons.wikimedia.org/w/index.php?curid=23231964)

Das Einstrom-Strahltriebwerk ist der Prototyp der Turbinentriebwerke. Wir verfolgen den Weg der Luft durch das Triebwerk und verdeutlichen die grundlegende Funktionsweise anhand von Zustandsberechnungen der Luft beim Durchströmen.

In Abbildung 2 wurden die beiden rechten Teilschemata zu Epoxydierung und Hydrolyse vertauscht. In der Legende zur Abbildung muss es Linolsäure statt Linolensäure heißen. Die korrigierte Abbildung finden Sie unten.

In this teaching unit, students use their own digital devices to determine the concentration of a dye in a sports drink. The method is gradually developed and carried out by learners, building their cognitive and practical foundations. A classic spectrophotometer is compared to a self-developed “smartphone photometer” setup. The teaching unit suggests that a deeper understanding is gained when students work out the necessary procedure and measurement principle themselves before becoming familiar with the actual device.

The history of spaceflight has been shorter than an average lifespan. Since 1961, around 600 humans have ever been in orbit. The extreme conditions of space add a new astronomical dimension to all the sciences known to us on Earth and require many protections and adaptations for a permanent space stay. It is foreseeable that the progress of manned space spaceflight, especially future new moon missions or even flight to Mars, will bring great impulses to the field of astropharmacy and astrotoxicology in the next decades.
