Turning the 'hydrogen economy' concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels.
Researchers have spent the past several years researching ways to harness plants' natural abilities to filter toxins out of the air into an application that could be used in indoor spaces like office buildings.
The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Ambitious mitigation efforts, however, could decrease the pollution by 50 percent. The analysis is the very first to quantify this.
In a new radiation receiver developed for solar tower power plants, ceramic particles of around one millimetre in size are heated to 1000 degrees Celsius. The particles are held in a drum inside the rotating receiver by centrifugal force, until they become hot enough to drive the steam turbine in a power plant, for example.
How can you ensure that people do not only spend time thinking about important global issues like climate change or world food supplies, but also roll up their sleeves and do something about them? Four researchers think that the education sector holds the key.
A multi-university team has addressed challenges of introducing advanced biofuels in the transportation pool through the concerted development of technology designed to transform lignocellulosic biomass into a jet fuel surrogate via catalytic chemistry. This promising approach highlights the versatility of lignocellulose as a feedstock.
Many harmful substances in waste water stubbornly resist being broken down by biological waste water treatment plants. Researchers have developed a photochemical reaction system in which water can be reliably treated at high flow rates by UV light without having to add chemical catalysts.
