New findings pave the way to environmentally friendly supercapacitors — ScienceDaily

Limited safety, sustainability and recyclability are key drawbacks of today’s lithium-ion battery technology, along with restricted availability of starting materials (e.g. cobalt). In the search for alternative electrochemical energy storage systems for use in e-mobility and for storing energy from renewable sources, a combination of battery and capacitor is very promising: the “hybrid supercapacitor.” It can be charged and discharged as quickly as a capacitor and can store almost as much energy as conventional batteries. In comparison to the latter, it can be charged and discharged much faster and much more frequently: while a lithium-ion battery achieves a service life of a few thousand cycles, a supercapacitor manages around one million charging cycles.

System made of carbon and salt water

A particularly sustainable, but so far quite unexplored variant of such a hybrid supercapacitor consists of carbon and aqueous sodium iodide (NaI) electrolyte, with a positive battery electrode and a

The Hologram AR Function Developed by Microsoft, Google, Apple, and WIMI Pave the way for Smart Wearable Device – Press Release

HONG KONG, Sept. 28, 2020 (GLOBE NEWSWIRE) — Many big tech companies are now developing smart glasses and AR helmets, hoping that they can replace smartphones one day. Microsoft, Google, and Apple all have their own products. If smart glasses can really replace phones and computers, it will certainly be a huge market.

Google

When Google Glass came out, it was said to have attracted lots of attention. The global attention of science and technology was focused on Google Glass; however, the first battle of Google Glass should be regarded as a failure. Google has launched a new version of business Google Glass, adding a lot of AR programs. The map part of the glass is more user-friendly, since it shows the specific route of the map in the glasses, and the parameters of other behaviors can also be seen.

Apple

Instead of glasses, Apple introduced a helmet. Apple plans

Ring Always Home Cam and Echo Show 10 may pave way for Amazon robot

  • Amazon launched two new smart home products that can move within the home: the Echo Show 10 and Ring Always Home Cam.
  • The Echo Show 10 can reorient its display, camera, and speakers to face the user’s direction, while the Ring Always Home Cam is a mini security drone that can fly around the home.
  • Both product could serve as a step toward Amazon’s broader ambitions to build an Alexa-enabled home robot, as reports from Business Insider and Bloomberg have indicated.
  • But the company will have to overcome serious privacy concerns along the way. 
  • Visit Business Insider’s homepage for more stories.

Amazon’s presence in the home took a big leap forward this week, and not just because the online retail giant announced a completely redesigned Echo lineup and big updates to Alexa.

Amazon’s smart home devices, whether it be an Echo speaker, Eero mesh router, or Ring security camera, have

Targeting RNA with small molecules could pave the way for new antivirals — ScienceDaily

A study appearing next week in the journal Nature Communications offers some good news in the search for antiviral drugs for hard-to-treat diseases. Researchers have identified a potential new drug candidate against enterovirus 71, a common cause of hand, foot and mouth disease in infants and young children.

The compound of interest is a small molecule that binds to RNA, the virus’s genetic material, and changes its 3-D shape in a way that stops the virus from multiplying without harming its human host.

There are currently no FDA-approved drugs or vaccines for enterovirus 71, which affects hundreds of thousands of children each year, particularly in Southeast Asia. While most people get better within 7 to 10 days after suffering little more than a fever and rash, severe cases can cause brain inflammation, paralysis and even death.

The work could pave the way for new treatments for other viral infections as
