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 ...

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 ...

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 ...

In a series of tests, oil modified with crumpled graphene balls outperformed some commercial lubricants by 15 percent, both in terms of reducing friction and the degree of wear on steel surfaces.

OrganamiCrumpled 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 ...

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 ...

Self-dispersed crumpled graphene balls in oil for friction and wear reduction. Proceedings of the National Academy of Sciences, 2016; 201520994 DOI: 10.1073/pnas.1520994113 ...
