A common problem with sunglasses is called back-glare. This is light that hits the back of the lenses and bounces into the eyes. The purpose of an anti-reflective (AR) coating is to reduce these reflections off the lenses. Similar to a scratch-resistant coating, AR is made of a very ...
They tend to only occur in the shallows, and the species that occur there tend to be both abundant and common. So while small patches of dead animals that result from them, overall they very likely play a minor if any role in the population size of those animals." Fortunately, they're...
These hand-picked National Geographic stories show how the world is bracing for—and embracing—its future.
under one scenario, and supply is not going to be sufficient by 2030 to meet that demand. If you look at lithium, for example, demand could be as much as 40 percent higher by 2030 than the current line of sight on expected supply. ...
Between episodes, patients with bipolar disorder exhibit depressive moodiness and sometimes high-energy activity; disruption in developmental and social functioning is more common than in unipolar disorder. When the sufferer is in the depressive episode they may suffer loss of interest, reduced energy, ...
What is lithium in the periodic table? What do atoms do in a chemical reaction? Explain the bond between lithium and nitrogen. What do a see-saw and a chemical balance have in common? How reactive are alkaline earth metals? Chlorine trifluoride usually reacts with metals to form t...
There are limitations to defining this as a single perspective, given a plurality in global values that should be acknowledged (IPBES 2022, 2024), though a common thread is seeing humanity as much more deeply interconnected and embedded in the web of life. We refer to these as relational ...
The cost of electricity is an input common to all the technology options considered and is taken from the SSP2 scenarios of the REMIND Integrated Assessment Model v.2.183. In 2030, it is assumed to be 0.064 and 0.074 €/kWh in the 3.5° and 2 °C scenarios, respectively. In 2050, ...
As demand accelerates and prices react, the industry is able to bring in new supply (for example, lithium) relatively quickly. In such cases, the technological transition follows the “expected” growth, where the commodity does no...
to produce materials for new batteries from recycled lithium batteries. It’s financed by more than half a billion dollars of recent private investment that builds on $480 million in Department of Energy grants, and the work is based on fundamental research that was supported by the National Sci...
