Fast-Charging, Noncombustible Batteries

AUSTIN, Texas — A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge.

“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted.

The researchers demonstrated that their new battery cells have at least three times as much energy density as today’s lithium-ion batteries.

The use of an alkali-metal anode (lithium, sodium or potassium) — which isn’t possible with conventional batteries — increases the energy density of a cathode and delivers a long cycle life.

Braga said that Goodenough brought an understanding of the composition and properties of the solid-glass electrolytes that resulted in a new version of the electrolytes that is now patented through the UT Austin Office of Technology Commercialization.

The engineers’ glass electrolytes allow them to plate and strip alkali metals on both the cathode and the anode side without dendrites, which simplifies battery cell fabrication.

Technologies present high risk in 2017

(Summary from: www.zdnet.com: Which technologies present the most risk in 2017?)

A lot of exciting new technologies are emerging or maturing that will likely play an increasingly important role in our lives and help transform businesses and industries in the coming months and years.

Jobs at high risk by automation

But many of these present potential risks from an information security and safety standpoint.

“Emerging technologies may have differing cyber security concerns than traditional IT systems, especially if they have components that impact the physical world, such as autonomous vehicles and smart medical devices,” said Dan Klinedinst, senior vulnerability analyst in the CERT Division of the Software Engineering Institute at Carnegie Mellon University.

Here are the technologies that CERT, a group that researches a variety of issues with cyber security implications, will be keeping a close watch on this year:

  • Autonomous cars
  • Commercial autonomous aerial vehicles
  • Autonomous Commercial Transportation
  • Smart robots
  • Robotic surgery
  • Augmented reality
  • Personal assistants
  • Machine learning/Big Data
  • Artificial intelligence
  • Building automation
  • Software Defined Anything
  • Internet of Things (IoT) Mesh Networks

Companies like Microsoft and Google are searching for better solutions for the geometrical increase in the volume of data transmissions demanded by their consumers. They are using more hardwares, and more energy to maintain their services. The by-product of it is the excessive heat to be removed.

Microsoft, now tries to solve that unwanted heat created by the data centers with a different strategy. Instead of using a cooling system running with liquid nitrogene, they are dipping their data centers into the ocean in steel tubes.

They are also planning to produce the required energy by the data centers using some off-shore power generators.

They hope that it will help somewhat for the global warming problems.

Maybe there are some cool solutions for our future under the depths of the oceans. Who knows?

Super-fast 5G Internet by Solar Powered Drones

In an article by BEC Crew in ScienceAlert.com it is said that Google is working on a secret project codenamed Skybender.

Super-fast 5G Internet

In the project a data transmission 40 times faster than the fastest wireless services is aimed.

The new data transmission will be made in a new spectrum with millimetric waves which covers a frequency range from 30 GHz to 300GHz.

Test are being maintained already in New Mexico.

“According to Engadget, Google has permission from the Federal Communications Commission (FCC) to continue testing their drones in US airspace till July this year, at which point we’ll probably hear more about the success or failure of Skybender. Regardless of what happens though, we get the feeling that those millimetre waves aren’t going to be left vacant for much longer.”

In 2015 there were some interesting scientific discoveries that possible will affect our future.

Here is a small derivation from some of these discoveries:

  • Supermassive black hole: It has a mass whic is 12 million times larger than our own sun.
  • Two more unknown planets estimated to to be existing farther than Pluto.
  • Human skeletal muscles raised in the laboratories that can respond like native tissue to external stimuli.
  • A high quality graphene produced at a cost of 1000 times cheaper than the average cost at Delt University.
  • The first human epigenome map is completed.
  • Researchers from North Carolina University discovered a new phase of carbon which gives the ability to produce diamond at room temperatures and normal athospheric pressures.
  • NASA finds possible evidence of flowing water on Mars
  • EM Drive becomes a reality according to scientists
  • New Horizons space probe reached Pluto
  • Scientist discovered the first warm-blooded fish
  • New species found in the Himalayas

I wish the best for everybody in 2016.

Talking walls from Kadikoy

The following murals are not new paintings. But I couldn’t find an appropriate time to fix them into my timeline.

Yes, at the end, even the atmospheric conditions were not ideal to photograph, I got a few shots from two murals today. Both of the murals are from the crossing of Talimhane and Reşit Efendi streets.

Now, I want to share them with you.
