Will we ever understand how life got started on Earth? We’ve learned much about Earth’s long, multi-billion-year history, but a detailed understanding of how the planet’s atmospheric chemistry evolved still eludes us. At one time, Earth was atmospherically hostile, and its transition from that state to a planet teeming with life followed a complex path. …

A plug-flow fixed-bed cell for synchrotron powder X-ray diffraction (PXRD) and X-ray absorption fine structure (XAFS) idoneous for the study of heterogeneous catalysts at high temperature, pressure and under gas flow is designed, constructed and demonstrated. The operating conditions up to 1000°C and 50 bar are ensured by a set of mass flow controllers, pressure regulators and two infra-red lamps that constitute a robust and ultra-fast heating and cooling method. The performance of the system and cell for carbon dioxide hydrogenation reactions under specified temperatures, gas flows and pressures is demonstrated both for PXRD and XAFS at the P02.1 (PXRD) and the P64 (XAFS) beamlines of the Deutsches Elektronen-Synchrotron (DESY).

A furnace that covers the temperature range from room temperature up to 2000 K has been designed, built and implemented on the D2AM beamline at the ESRF. The QMAX furnace is devoted to the full exploration of the reciprocal hemispace located above the sample surface. It is well suited for symmetric and asymmetric 3D reciprocal space mapping. Owing to the hemispherical design of the furnace, 3D grazing-incidence small- and wide-angle scattering and diffraction measurements are possible. Inert and reactive experiments can be performed at atmospheric pressure under controlled gas flux. It is demonstrated that the QMAX furnace allows monitoring of structural phase transitions as well as microstructural evolution at the nanoscale, such as self-organization processes, crystal growth and strain relaxation. A time-resolved in situ oxidation experiment illustrates the capability to probe the high-temperature reactivity of materials.

A scanning soft X-ray spectromicroscope was recently developed based mainly on the photon-in/photon-out measurement scheme for the investigation of local electronic structures on the surfaces and interfaces of advanced materials under conditions ranging from low vacuum to helium atmosphere. The apparatus was installed at the soft X-ray beamline (BL17SU) at SPring-8. The characteristic features of the apparatus are described in detail. The feasibility of this spectromicroscope was demonstrated using soft X-ray undulator radiation. Here, based on these results, element-specific two-dimensional mapping and micro-XAFS (X-ray absorption fine structure) measurements are reported, as well as the observation of magnetic domain structures from using a reference sample of permalloy micro-dot patterns fabricated on a silicon substrate, with modest spatial resolution (e.g. ∼500 nm). Then, the X-ray radiation dose for Nafion® near the fluorine K-edge is discussed as a typical example of material that is not radiation hardened against a focused X-ray beam, for near future experiments.

This article presents the capability of the QMAX furnace, devoted to reciprocal space mapping through X-ray scattering at high temperature up to 2000 K.

Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small.

Although there have been significant advances in the understanding and monitoring of atmospheric processes in the last decade, a recent study suggests that uncertainties in their assessment continue to grow and more complex studies are required to understand the precise relationship between atmospheric chemicals, such as air pollutants, and climate change.

Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.

Four ozone-depleting gases, previously undetected in the atmosphere, have been found by new research. The work suggests that more than 74 000 tonnes of these human-made substances have been released since 1978, and that two are continuing to accumulate in the atmosphere. However, it is not yet known where they come from.

Nitrous oxide (N₂O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N₂O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N₂O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N₂O emissions.

Combinations of atmosphere control members are used to control the atmosphere within a sealed container which contains a respiring biological material. The combination makes use of a first ACM having a first R ratio (the ratio of carbon dioxide permeability to oxygen permeability) and a second ACM having a second R ratio, the first R ratio being substantially greater than 1.0, and the second R ratio being less than the first R ratio. This combination (31, 321, 322, 331, 332) can form part of the sealed container (1) itself, or can be part of an assembly (31, 32, 34) through which the packaging atmosphere within the sealed container (1) is circulated.

Sean “Slug” Daley of Atmosphere is a proud son of Minneapolis whose devotion to that city shines through not only in his music, but also in the label he co-founded in large part to help bring shine to his city’s scene, Rhymesayers.

Atmosphere started when Daley was in high school (see above), but the group really started making waves in the early 2000s, with the release of music that would be collected on the album Lucy Ford: The Atmosphere EPs.

The introspective, personal songs on Lucy Ford and follow-up projects like God Loves Ugly and Seven’s Travels struck a chord with a huge audience, and Atmosphere’s constant touring, of a kind much more akin to rock bands than rap acts, helped the group’s following grow to a point where they received airplay on MTV2, performed at large festivals, and received serious attention from big record labels. Rhymesayers, meanwhile, released well-regarded projects from the likes of Brother Ali, Eyedea and Abilities, Blueprint, MF DOOM, and many others.

Atmosphere’s latest album, released this past August, is Fishing Blues.
