最后三句The two-dimensional ribbons have a number of remarkable properties. Their unbelievable width allows their properties, such as whether and how they conduct electricity, to be controllable. They are also very flexible, which means that they can follow any surfaces they're put on perfectly,...
More than 100 scientific papers predicted the transformative potential of these ribbons, should it be possible to create them, across a range of technologies — some as many as five years before the publishing of our discovery in Nature. Perhaps the most important of these is in the area of ...
The authors link water and electricity system models to evaluate how the electric grid can both adapt to climate change impacts and decarbonize, while also accounting for dependencies and climate vulnerabilities of the closely coupled water sector. ...
Fleming is a delightful record of the research, discovery, and development which has lain behind the infusion of electricity into the life of civilised lands over the last fifty years. It is written with the intimate knowledge and enthusiasm of one who has himself been a worker and a keen ...
We achieved a more compact footprint using a single turbo-pump with six-stage pumping, which allowed for fewer moving parts, lower electricity consumption, less noise and weight. Ion path and key components...
The discovery made him bold enough to imagine that if the current intensity changes, the sound waves will be simulated, Then the current transfer of voice can be achieved. So Baer consulted Henry, an electrical expert, and learned the knowledge of electricity himself and continued his research....
