Crumpled paper balls don’t just look like brains—they act like them too. Larger brains tend to be more wrinkly than smaller brains, and because of this scientists have long thought that the ...

The crumpled balls can move apart when lithium deposits and then readily assemble back together when the lithium is depleted. Because miniature paper balls are conductive and allow lithium ions to ...

The solution lies in a scaffold made from crumpled graphene balls, which can stack with ease to form a porous scaffold, due to their paper ball-like shape. They not only prevent dendrite growth ...

Indeed, crumpled paper ball-like graphene particles have scalable Li loading up to 10 mAh cm−2 within tolerable volume fluctuation. High Coulombic efficiency of 97.5% over 750 cycles (1,500 hr) was ...

About five years ago, Huang discovered crumpled graphene balls -- a novel type of ultrafine particles that resemble crumpled paper balls. The particles are made by drying tiny water droplets with ...

Crumpled Graphene Balls Stabilized Dendrite-free Lithium Metal Anodes. Joule, 2018; 2 (1): 184 DOI: 10.1016/j.joule.2017.11.004 ...

Building better batteries using crumpled graphene balls By Nick Lavars January 22, 2018 The engineers have filed a provisional patent for their crumpled graphene ball battery View 1 Images ...

Back in 2007, photographer Thomas Brown had an idea to make a paper ball look like a meteor. However, as he started showing his friends and colleagues his work, people were seeing everything but ...

About five years ago, Huang discovered crumpled graphene balls — a novel type of ultrafine particles that resemble crumpled paper balls. The particles are made by drying tiny water droplets with ...

He achieved as much with his 1995 creation, “Work No. 88,” a single piece of A4 paper crumpled into a ball. ... (A crumpled ball is a collection of d-cones connected by ridges.) ...

Making the connection between balls of crumpled paper and the balls of folded tissue in our skulls was completely accidental. The universal scaling law that governs the folding of paper has been ...
