There have been many, many discoveries that promise longer battery life, but one of the latest is rare in taking its inspiration from one of the most common structures in nature: the leaf vein. Scientists have crafted a porous material that mimics the highly optimized flow of nutrients in plant leaves. The team used an evaporation-based process to arrange zinc oxide nanoparticles into networks with pores of various sizes that behave like you’d expect in a leaf, maximizing the transfer of material while minimizing the necessary energy.
