Scientists Take Big Step Towards Using Light instead of Wires in Computers

Compared with electricity which can transmit data via wires, light should be more efficient in this regard. However, there is still some problem in the way to make it reliably work in a computer. Recently a group of engineers headed by Jelena Vuckovic of StanfordUniversity has announced a brand-new “optical […]

Hybrid Material May Smash the Ceiling of Solar Cell Efficiency

In the process of photosynthesis, only 10% of the light plants receive from the sun is turned into usable hydrogen to help the reaction. Last summer, some scientists succeeded in reaching world-record 44.7% with a new cell in regard to laboratory efficiency, and their final goal would be 50%. However such record […]

Using Beach Sand to Make Li-Ion Batteries That Last Longer

Charge your phone with that white stuff from the beach. According to the latest study released in the journal of Scientific Reports, beach sand can be used to make lithium-ion batteries that last three times longer compared with the present models. Talking of this new invention, Zachary Favors, a graduate student at […]

Using Soluble Circuits to Reduce End E-Waste

It takes 1,000 years for a typical silicon wafer to dissolve in a bucket of water. Now the world population is up to seven billion. For each of us living on the earth, 43 pounds of electronic waste is generated every year. As predicted by the United Nations, this figure […]

A Lithium-Ion Battery Can Be Stretched by 600%

According to the study published in the Journal of Materials Chemistry, a group of scientists from Fudan University, China, has developed kind of lithium-ion battery with the superb stretch up to 600%, but at the same time, it is still capable of maintaining its amazing electrochemical properties. At present, stretchy electronic […]
