#zrodlo

In today's 'internet of things,' devices connect primarily over short ranges at high speeds, an environment in which surface acoustic wave devices have shown promise for years. To obtain faster speeds, however, SAW devices need to operate at higher frequencies, limiting output power and overall performance. Researchers have demonstrated a new device that can achieve frequencies six times higher than most current devices. Their results are published this week in Applied Physics Letters.

A water-based, rechargeable battery

Added: 09.01.2018 12:53 | 0 views | 0 comments

#zrodlo

In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves a question: Why not simply use water as an electrolyte? Water is cheap, in abundant supply, doesn’t burn and can conduct ions. But it has one major drawback: It is only chemically stable up to a voltage of 1.23 volts. In other words, a water cell provides three times less voltage than a customary lithium ion cell with 3.7 volts, which makes it poorly suited for applications in an electric car. A cost-effective, water-based battery, however, could be extremely interesting for stationary electricity storage applications.
