The removal of arsenic from water using a brown seaweed (Sargassum muticum), coated with iron hydroxide, has been tested in a recent study. Under optimal pH conditions, the method removed 100% of the arsenic, indicating the viability of this method for treating contaminated water.

Water pollution by toxic elements is a major economic and environmental concern, and mercury is one of the most poisonous of the elements to be released into the environment by industry. Mercury exposure can cause severe ill health. Efficient, simple and convenient methods to remove mercury from industrial and other waste streams and drinking water are essential. This study successfully trialled a new technique, using magnetised multi-walled carbon nanotubes (MWCNTs), to remove mercury from waste water.

Innovatively designed batteries offer a way for vehicles to move away from their dependence on fossil fuels. There has been little mass-market uptake of new battery design, however. In the last century, only four types of battery have been used: manganese oxide; lead acid; nickel; and lithium ion, which is a relative newcomer, introduced in 1991. To understand how innovation moves from research and development (R&D) to application and the mass market, scientists perform technology lifecycle (TLC) analyses, often focusing on R&D and basic research. This study adds an additional indicator — start-up companies — to explore the early phases of how batteries transition from science into industry.

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.
