It seems like everything we own is now rechargeable: phones, lights, watches, and internet connected dildos. To facilitate our sexy, cordless existence, all of these devices need a battery. The problem is that the batteries used for our strangulation-proof-life become degraded by frequent recharging. The sort of frequent recharging required during an all-night, swipe right binge on tinder so you can confidently look your mum in the eye and say that you are trying to find someone.
The vascular structures created by the scientists are similar to those you’d find on the back of leaves, in circulatory systems and, even though the scientists don’t explicitly mention it in their paper, on the top of willies so big they have their own soul.
In a first of its kind demonstration, the superficial-dorsal-vein-loving-scientists use what is known as Murray’s Law to inspire material design. Murry’s Law is basically a formula to explain how natural systems minimise resistance in vessels. It all starts with a big vessel which has “daughter” branches that are smaller in diameter.
In the case of a willy, the superficial dorsal vein is the main pathway which then branches off into smaller and smaller veins. This hierarchal structure ensures the hard working willy gets all of the nutrients it needs in a super efficient way.
The blue-vein-imitating-scientists created their Murry material by allowing zinc-oxide nanoparticles to self-arrange through a simple layer by layer evaporation process. By changing the solvent and temperature used for the evaporation of different layers, the “rear of the year” scientists were able to change the size of the pores created by the nanoparticles.
Prof Bao-Lian Su, who holds a number of positions: as a life member of Clare Hall, University of Cambridge, Wuhan University of Technology in China and at the University of Namur in Belgium because he hates spending time with his family said,
“sometimes all the inspiration you need is right under your nose…or between your knees and nipples to be exact”
When used in a battery, the zinc oxide Murray material had a reversible capacity 25 times higher than that of a state-of-art graphite Li-ion battery electrode. The bio-inspired ZnO Murray network, with its vascular network of pores, delivered ultra-high capacities and rate capabilities, along with long-life cycling stability.
The branching nature of the pores also reduces the stresses in these electrodes during the charge/discharge processes, improving their structural stability and resulting in a longer lifetime for energy storage devices.
The team envisions that the same willy inspired structures could be used effectively in material designs for energy and environmental applications and promise that their next paper will mention where they really got the inspiration from.
I will never run adverts so I’d love for you to buy me a coffee:
- Bio-inspired Murray materials for mass transfer and activity
- Leaf vein structure could hold key to extending battery life
