you must not throw sundry, especially those serious pollution of garbage, waste batteries, for example, because the section waste batteries contain heavy metals, if flow to clean the water, it is very much pollution, then try to save trees made items such...
And there are also concerns around the safety and sustainability(可持续性) of ithium batteries.Mining the metals needed for them comes with a high social and environmental cost.This has urged scientists around the world to try and develop new types of battery that can overcome theseproblems. ...
Thousands of objects were discovered in the bay, including bottles, metals, plastics, etc. “Bergen is a place where different industries come together, and the city is quite old, so there’s a huge amount of rubbish,” said Trygve Olav Fossum, one of the researchers. “We think the ...

Semiconductors are in everything from your cell phone to rockets. But what exactly are they, and what makes them so special? 先来一个小实验帮助我们理解。我们有一个断开的带有电池和灯泡的电路,如图1所示:I have a circuit with a battery, a light bulb, and gap, as shown in Figure 1: 图...
In essence, every battery consists of a cathode, an anode and an electrolyte. Inconventional lithium-ion batteries, the anode is made of graphite, and the cathode material is a mixed oxide oflithiumand other metals, such as lithium cobalt(III) oxide. The electrolytes are used as transmitters...
How to light up a light bulb without electricity. In power plants, generators convert mechanical energy into what? What are particles of radiant energy called? What unit is used to measure electricity? Which metals exhibit the photoelectric effect?
Building an investment portfolio may require personalization and finesse, but it can also be ultra-simple.
As you might suspect, lithium-sulfur batteries use lithium and a sulfur to produce their electrical charge. Lithium-sulfur batteries are relatively new, and differ in many ways from the more common lithium ion batteries. Because they use no heavy metals in their construction, these batteries have...
