Trapping Xe in Nanocages Using a Plasma
Silicate nanocages supported on metal powders trap xenon (Xe) atoms when exposed to a Xe plasma. Three major advances are achieved in this work including trapping Xe in (1) high‐surface‐area powder materials, using (2) a nonprecious metal support, and (3) a simple ionization method.

The Temperature of Meteorites [PDF]
DURING the early part of the year 1901, when I was on the staff of the Elswick Works, it occurred to me that it would be useful and interesting if a connection could be made between the conditions of the flight of artillery shells and of meteorites. Later in the same year I made a preliminary mathematical investigation into the matter, and as a result ...

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems
Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Abstract We examine the number of sites with silver objects in China over a period of 3500 years to suggest that technologies that stimulated the indigenous exploitation of silver‐bearing ores were innovated during the Spring and Autumn period (c. 770–476 BCE), and that increased centralisation and bureaucratisation from the Warring States period (475 ...

Crater lakes in core regions of former ice sheets have the potential to preserve long‐term sedimentary archives that are otherwise rare in glaciated landscapes due to pervasive glacial erosion. Lake Wiyâshâkimî, an impact crater lake located in the inner core of the Québec‐Labrador Dome of the Laurentide Ice Sheet, provides a rare example of such a ...
