The house of the future could never let your smartphone battery die


A die the most mundane mistakes I make can derail my day: I go to bed, I brush my teeth and I forget to charge my smartphone. I wake up to a phone with 20% battery, no time to charge it before I have to rush out the door and take a long subway ride where I answer my emails as I go. measure. By the time I’m in the office, my phone is almost dead – and I forgot my charging cable.

Surely there is a better way. And luckily, scientists from Kookmin University and the Kumoh National Institute of Technology in South Korea agree. In a recent study published in ACS Nanoa team of researchers lays out their vision of a future where households can charge their electronic devices simply by leaving them lying around the kitchen.

What’s new – Specifically, the researchers developed a way to exploit the granite and marble countertops found in some (well-appointed) kitchens to serve as extremely convenient charging stations for smartphones, watches, and other devices. .

They’ve designed tiny supercapacitors that coat even slightly porous stone surfaces, like those found in kitchens. They then superimposed their innovation on marble and fired a laser at it to charge the device. Not only did it do a good job of conserving power, but it maintained performance even after 4,000 charge-recharge cycles. By stacking these devices on a kitchen counter and introducing a power supply, one could build a full-scale charging area in their home, or perhaps a charging wall, or even a stone bench.

The researchers say their innovation “represents a class of ubiquitous, low-cost, environmentally friendly and recyclable energy storage interface for sustainable development and easily accessible. [energy storage solutions].”

It should be noted that the researchers conducted a rather amusing test of their system: “The proposed energy system also underwent a series of rigorous mechanical reliability tests, including being stepped on with shoes, intensive crushing on the floor and repetitive hammer blows.”

There’s no telling if it stands up to the inevitable kitchen nightmare: spills.

On the horizon: new physics at the LHC

The Large Hadron Collider is essentially a long, very high-tech tunnel buried under the Franco-Swiss border. With 27 kilometers in circumference, the LHC is the largest particle collider in the world. And after a years-long hiatus for maintenance, it’s back online and discovering new particles left, right and center.

Want to get to know each other better? Read our story about the LHC and what is perhaps its most famous discovery to date, the Higgs boson. Discovered ten years ago on July 4, 2012, we revisit this defining moment in the world of fundamental physics.

Giulia Zanderighi is head of a particle physics group at the Max Planck Institute for Physics and co-author of a perspective published this week in Nature on the occasion of Higgs’ birthday. She said Reverse that CERN’s research on the Higgs boson is always at the forefront of scientific knowledge.

“Each time a measurement becomes more precise, we can refine the allowed models of new physics,” says Zanderighi. “So we are getting closer to determining possible physics beyond the Standard Model.”

Beyond the horizon…

Michael Pollan, a popular health and wellness author, presents a new documentary on Netflix about psychedelics, titled How to change your mind. The show premieres Tuesday, July 12.

Covering LSD and mescaline, among other psychoactive substances, Pollan promises an in-depth look at the science behind how these drugs might affect the brain and how they might be harnessed for medical treatments.
