Nettle as a distinct Bronze Age textile plant
(Peer reviewed; Journal article, 2012-09-28)It is generally assumed that the production of plant fibre textiles in ancient Europe, especially woven textiles for clothing, was closely linked to the development of agriculture through the use of cultivated textile ... -
Network analysis of geomagnetic substorms using the SuperMAG database of ground-based magnetometer stations
(Peer reviewed; Journal article, 2015-09-26)The overall morphology and dynamics of magnetospheric substorms is well established in terms of the observed qualitative auroral features seen in ground-based magnetometers. This paper focuses on the quantitative ... -
Neutral atom and molecule focusing using a Fresnel zone plate
(Peer reviewed; Journal article, 2008)Focusing of neutral atoms and molecules has several potential applications. The very first microscopy images using helium as an imaging probe were published earlier this year. Another possible application is to study the ... -
A neutral matter-wave microscope (NEMI): Design and setup
