Researchers from China create graphene aerogel that converts sunlight into heat to produce water vapor at room temperature

Graphene aerogel assists water treatment image

Researchers at the Chinese Hubei University have designed a graphene aerogel film capable of producing water vapor at room temperature using only sunlight. The aerogel floats on the surface, where it heats up only a small part of the water … Continue reading

Physicists have found a metal that conducts electricity but not heat

Share to TwitterShare to FlipboardShare to Copy LinkResearchers have identified a metal that conducts electricity without conducting heat – an incredibly useful property that defies our current understanding of how conductors work. The metal contradicts something called the Wiedemann-Franz Law, … Continue reading

Scientists create first 2-D electride

Researchers have brought electrides into the nanoregime by synthesizing the first 2D electride material. Electrides are ionic compounds, which are made of negative and positive ions. But in electrides, the negative “ions” are simply electrons, with no nucleus. The electrons … Continue reading

A material that’s better than graphene?

What could be better than a material that’s super flexible, only one atom thick, and is 200 times stronger than steel? A material that’s equally strong and flexible, also only one atom thick, and inexpensive. Scientists are asserting that this new discovery could potentially upstage the world’s … Continue reading

THE IDEA OF pH VALUE

Today Alan Mason helps us understand pH. Ideas of acidity, alkalinity and neutrality have been known about for centuries, hence the common language terms, but it was only in the early twentieth century that the concept was fully understood scientifically, … Continue reading
