Scientists develop fast method of detecting toxin from pesticides and chemical weapons
A group of Australian researchers has developed a new and fast method of detecting a dangerous toxin from pesticides and chemical weapons. The study, published in the journal ACS Nano, explains how perovskite nanocrystals, which were being used to develop new solar panels, can change color upon detecting methyl iodide. Methyl iodide, also known as iodomethane, is a colorless […]

DISCOVERY: Luminescent “windows” could transform light into power
Engineers from Rice University in Houston developed a novel method of generating power through the use of glowing “windows” that redirect light to the solar cells lining their edges. The windows, known as luminescent solar concentrates (LSCs), are composed of a conjugated polymer sandwiched between two acrylic panels. The polymer, a light-emitting compound dubbed PNV (poly[naphthalene-alt-vinylene]), is designed to absorb light from the […]

This fascinating off-grid lamp is powered by photosynthesis
Dutch designer Ermi van Oers has created an off-grid lamp that uses a living plant to produce light. The device, dubbed “Living Light,” uses microorganisms of plant origin to convert the chemical energy that a plant naturally produces during photosynthesis into an electric current. The lamp is fully self-sufficient, meaning it doesn’t have to be plugged […]

Scientists create sponge-like material to soak up phosphate from polluted waters
Researchers from Northwestern University in Illinois have created a sponge-like material capable of removing up to 99 percent of phosphate ions in polluted water. The “sponge,” technically known as the Phosphate Elimination and Recovery Lightweight (PEARL) membrane, is coated with nanostructures that bind to the phosphate ions. By fine-tuning the pH level of the sponge, the researchers can […]

This innovative skylight uses light from the sun to desalinate water for drinking
Designer Henry Glogau has developed a skylight that uses seawater to provide natural ambient light and clean drinking water. The device is charged by a mini solar panel during the day. The remaining sea salt is also funneled into a dozen zinc and copper batteries that power a strip of light-emitting diodes (LEDs). Glogau’s device, which he dubbed […]

Fuel for the future: Chemist develops ammonia fuel cells that “bottle” sunshine and wind
Ammonia may become the foundation of the future of sustainable energy. But until recently, the production of ammonia has been extremely energy-intensive. At the core of each ammonia factory are steel reactors that still use a century-old recipe for making ammonia: the Haber-Bosch process. The recipe entails generating up to 250 atmospheres of pressure to split the chemical bond […]

Scientists turn single-use plastics into jet fuel
Single-use plastics like plastic bags and plastic bottles could provide airplanes with the fuel they need to fly. In a recent breakthrough, a team of researchers from the University of Delaware found a way to break down single-use plastic waste into smaller carbon molecules, which can be used for jet fuel and diesel. Using an energy-efficient […]

New research shows plants grow just fine in solar cell greenhouses
Greenhouses fitted with semitransparent organic solar cells (ST-OSCs) can generate power for heating without affecting plant growth, according to new research from North Carolina State University (NCSU). Published in Cell Reports Physical Science, it demonstrated that ST-OSCs could turn greenhouses into energy-neutral structures by capturing energy from wavelengths of light not used by plants during photosynthesis. ST-OSCs don’t affect plant growth The […]

Good vibrations: Quiet, bladeless wind turbine can generate power without harming wildlife
Bladeless wind “turbines” that wobble like inflatable tube “guy” outside car dealerships could be the wind-harnessing tool of the future. The current design stands 10 feet tall and generates about 100–200 kilowatts (kW), according to a recent report from The Daily Mail. David Yanez invented these turbines, known as the Vortex Bladeless. His six-person startup, based just […]

Greener materials: Scientists use algae to make light carbon fibers that are as hard as steel
Algae is a diverse group of aquatic organisms capable of producing oxygen and absorbing carbon dioxide from the atmosphere. Scientists have been studying algae for their potential as a source of fuel, but many others are also starting to explore algae’s immense potential in biotechnology. In the algae technical facility at the Technical University of Munich […]
