Releasing the accumulating heat in graphene and carbon nanotube junctions can cause a series of problems. However, researchers at Rice University have come up with a solution to counter the problems the heat creates. They think that a cone-like chimney can be created between the two junctions so that the trapped heat can escape.

The graphene and nanotubes have to be tweaked to insert the cones that can create a vent for the heat. Heptagonal rings are formed when nanotubes are molded by graphene; these trap the heat inside. The cones may act as outlets to clear the path for the heat to race up to the chimney. This novel solution by Rice University research can help to eliminate harmful heat from modern nano-electronics.

The experiments were conducted at the lab of theoretical Rice University physicist Boris Yakobson. The research into these experiments can be found in the American Chemical Society's Journal of Physical Chemistry. It explains that spreading out the heptagons can allow photons to carry heat in a better way for faster transition.

While this phase of advancement is still under consideration, a research about energy applications (also by Rice University) has made the news. Their idea of fuel cells has become a recognized solution for powering vehicles. 

The 3D architecture model of their fuel cell solution shows that enough hydrogen can be stored in the cells that can practically work as a fuel for light-duty vehicles. It surpasses the mark of DoE, which states that at least 5.5 percent of a cell's weight should be composed of hydrogen to be termed acceptable. Rice team's model can store 12 percent of its weight in hydrogen, which can then even be scaled.
