TU Graz Explores Cultural Heritage Preservation in the Himalayas

Using 3D technology and interdisciplinary expertise, a research team has explored Buddhist temples in the remote Dolpo region of Nepal and digitized them for posterity In the high-altitude and extremely remote region of Dolpo in north-west Nepal, there are numerous Buddhist temples whose history dates back to the 11th century. The structures are threatened by earthquakes, landslides and planned infrastructure projects such as the Chinese Belt and Road Initiative. There is also a lack of financial resources for long-term maintenance….

Materials chemistry: When additives are good

Soft magnetic materials can be easily magnetized and demagnetized. They are widely used in microwave devices, such as absorption of electromagnetic radiations.Developers tend to use thin films of soft magnetic materials, as opposed to their bulk form, in mobile applications, such as cell phones and laptops, as well as military applications, such as stealth aircrafts. However, the conventional approach to making soft magnetic films requires a high vacuum environment, which is expensive and time-consuming. Moreover, the usual fabrication system is not suitable for the preparation of large sheet films, thereby limiting its application in manufacturing the soft magnetic materials for microwave absorption….
