Using DNA Templates to Harness the Sun's Energy

Double-stranded DNA as a template to guide self-assembly of cyanine dye forming strongly-coupled dye aggregates. These DNA-templated dye aggregates serve as "exciton wires" to facilitate directional, efficient energy transfer over distances up to 32 nm.

As the world struggles to meet the increasing demand for energy, coupled with the rising levels of CO2 in the atmosphere from deforestation and the use of fossil fuels, photosynthesis in nature simply cannot keep up with the carbon cycle. But what if we could help the natural carbon cycle by learning from photosyn

Modified 'White Graphene' for Eco-Friendly Energy

This is a catalyst with functionalized hexagonal boron nitride and nickel nanoparticles.

Scientists from TPU, Germany, and the United States have found a new way to functionalize a dielectric, otherwise known as 'white graphene', i.e. hexagonal boron nitride (hBN), without destroying it or changing its properties. Thanks to the new method, the researchers synthesized a 'polymer nano carpet' with strong

Paving the Way for Clean Hydrogen Energy

Fast and accurate sensors will be crucial in a sustainable society where hydrogen is an energy carrier. Hydrogen gas is produced by water that is split with the help of electricity from wind power or solar energy. The sensors are needed both when the hydrogen is produced and when it is used, for example in cars powered by a fuel cell. In order to avoid the formation of flammable and explosive gas when hydrogen is mixed with air, the hydrogen sensors need to be able to quickly detect leaks

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Chalmers University of Technology, Sweden, present the first hy

Carbon-Negative Power Generation for China
If we're going to limit global temperature increases to 2 degrees above pre-industrial levels, as laid out in the Paris Climate Agreement, it's going to take a lot more than a transition to carbon-neutral energy sources such as wind and solar. It's going to require carbon-negative technologies, including energy sourc
