A soil microbial fuel cell where microbes in dirt could power applications which are literally “in the field”.

When you are buying a new TV, you'll still see these resolutions. Which is better: 1080i, 1080p or 4K? Let's explore.

Backscatter imaging is primarily a compositional imaging mode, although it can be used on samples which exhibit excessive charging or on samples which provide poor SE images. The BSE detector can ...
