Secondary Ion Mass Spectrometry

In light of vehicular pollutants contributing to decreasing air quality, governments across the globe are posing stricter emission regulations for automobiles. This calls for the development of more efficient exhaust gas after-treatment systems, which are systems to "clean" exhaust gas before it is released into the atmosphere).

Researchers at Heidelberg University are studying the formation of this characteristically blue-colored crystal in volcanic melts

Water makes up 71% of Earth's surface, but no one knows how or when such massive quantities of water arrived on Earth.

The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer and lower free troposphere. This leaves large gaps in predictions of anthropogenic changes in the atmospheric energy balance.

Researchers have used a common disinfectant and antiseptic to create a new antimicrobial coating material that effectively kills bacteria and viruses, including MRSA and COVID-19.

The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount of water has broad implications for understanding how Earth's lower crust forms, how magma erupts through the crust, and how economically important mineral ore deposits form, according to a new article.

Decommissioning and clean-up are ongoing at the Fukushima Daiichi Nuclear Power Plant (FDNPP); however, many difficult problems remain unaddressed. Chief amongst these problems is the retrieval and management of fuel debris.

The most ancient evidence of life on our planet dates back roughly 3.5 billion years ago.

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

A detailed analysis of the Winchcombe meteorite has found evidence that its parent asteroid was altered by water before being smashed apart multiple times.

Entropic repulsion caused by interfacial orientational fluctuations of cholesterol layers restricts protein adsorption and bacterial adhesion, providing a conceptually new physicochemical perspective on biointerfaces that may guide future material design in regulation of adhesion.

Planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since the Solar System's formation around 4.5 billion years ago.

Testing shows that a 46 million-year-old fossilized mosquito, found by amateur fossil hunters in Montana, contains the blood of an unknown ancient creature

A pilot study from North Carolina State University shows that nanoscopic 3D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation. The work appears in iScience.

A team of researchers at the University of Nottingham's School of Pharmacy has developed a new antimicrobial coating material that effectively kills bacteria and viruses, including MRSA and Covid-19. The material is made by coating acrylonitrile butadiene styrene (ABS), a commonly used plastic, with chlorhexidine, which is often used by...

Since the initial discovery of what has become a rapidly growing family of two-dimensional layered materials—called MXenes—in 2011, Drexel University researchers have made steady progress in understanding the complex chemical composition and structure, as well as the physical and electrochemical properties, of these exceptionally versatile materials. More than a decade later, advanced instruments and a new approach…

Geologists at the Woods Hole Oceanographic Institution (WHOI), MIT, and elsewhere find colliding continental plates may draw down more water than previously thought. This could help explain the explosiveness of some volcanic eruptions and the distribution of ore deposits such as copper, silver, and gold.

Extreme weather events can exert profound impacts on society, economy and environment. However, short instrumental data limits our understanding of their mechanism and the evaluation of climate models.
