Expanding the use of silicon in batteries, by preventing electrodes from expanding

ScienceDaily.com: Nanotechnology News - 21 февраля, 2019 - 21:03
Silicon anodes are generally viewed as the next development in lithium-ion battery technology. Silicon's ability to absorb more charge translates to longer battery life and smaller batteries, if researchers can check the physical expansion of the silicon that comes with charging. Research suggests that adding MXene ink to the silicon electrode-making process would do just that.

Applications of carbon materials derived from metal-organic frameworks (MOFs)

Nanowerk.com - 20 февраля, 2019 - 18:10
Directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons, widely used as electrode materials, due to its flexibility and simplicity. These materials present certain drawbacks, though, such as low surface areas, disordered structures, and non-uniform sizes, which will greatly limit their applications. However, researchers found that carbon materials derived from metal-organic frameworks (MOFs) could overcome these limitations. A review summarizes the applications of MOF-derived carbon materials.

Powering a pacemaker with a patient's heartbeat

ScienceDaily.com: Nanotechnology News - 20 февраля, 2019 - 16:26
Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they have to be replaced surgically. Now, researchers have surmounted this issue by designing a pacemaker powered by the energy of heartbeats. The device was successfully tested in pigs, which have a similar physiology to humans.
