Achieving a supercapacitor through the ‘molecular coating’ approach

Posted by in categories: materials, mobile phones

Researchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. The research is published in the journal ACS Applied Materials & Interfaces.

A capacitor is a device used as part of a circuit that can store and release energy, just like a battery. What makes a capacitor different from a battery is that it takes much less time to charge. For example, your cellphone battery will power your phone instantly, but charging that back up to 100% when it dies is far from instantaneous.

While this makes capacitors sound like the superior choice, they have some big drawbacks that need to be overcome. First, their is much smaller than batteries, so they cannot store large amounts of energy at once. Second, they can be quite expensive.

T-Mobile Customers Will Get Starlink Satellite Internet Directly On Their Mobiles First And Others Only Later, Says SpaceX CEO Elon Musk

Posted by in categories: Elon Musk, mobile phones, satellites

SpaceX CEO Elon Musk said on Saturday that T-Mobile US Inc. TMUS subscribers in the U.S. will get direct to mobile phone internet with the help of Starlink satellites first and other telecom service providers later.

What Happened: “Starlink direct to mobile phone Internet is exclusively with Tmobile in the US for the first year, then other carriers thereafter,” Musk wrote on X. “We are starting off working with one carrier in each country, but ultimately hope to serve all carriers.”

Musk’s comment comes on the heels of SpaceX launching 26 Starlink satellites with direct-to-cell capabilities to low-Earth orbit on Saturday.

Verizon to bring satellite connectivity to Android phones this fall

Posted by in categories: mobile phones, satellites

TAMPA, Fla. — Verizon is launching satellite-enabled emergency text and location services this fall for compatible Android smartphones in the United States at no extra cost for customers.

The telecoms giant announced a partnership Aug. 28 to deliver the service with Skylo, which has developed ground infrastructure enabling L-band geostationary satellites to reach devices using the latest standards-based chipsets.

Google’s family of Pixel Pro devices and the Samsung Galaxy S25 are set to be among the first to get access to Skylo’s partner satellites, enabling emergency narrowband connectivity when cell towers are out of reach.

Engineers develop new two-dimensional, low-power-consumption field-effect transistor

Posted by in categories: mobile phones, robotics/AI

A team of electrical and computer engineers at Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, working with one colleague from City University of Hong Kong and another with Fudan University, has developed a new two-dimensional, low-power-consumption field-effect transistor (FET) that could allow smartphones to need recharging less often.

In their paper published in the journal Nature, the group describes how they overcame problems with high gate leakage and low dielectric strength that have stymied other researchers looking to create smaller and thinner computer chips. Two of the team members (Ziao Tian and Zengfeng Di) have published a Research Briefing, summarizing their work in the same journal issue.

Over the past several years, have been searching for new materials that will allow further miniaturization of silicon field-effect transistors. This will enable the addition of more features in phones and other devices without making them bigger. It is also a necessity for the development of 5G devices that will come with AI applications that are still in development.

Study of disordered rock salts leads to battery breakthrough

Posted by in categories: engineering, mobile phones, nuclear energy, sustainability, transportation

For the past decade, disordered rock salt has been studied as a potential breakthrough cathode material for use in lithium-ion batteries and a key to creating low-cost, high-energy storage for everything from cell phones to electric vehicles to renewable energy storage.

A new MIT study is making sure the material fulfills that promise.

Led by Ju Li, the Tokyo Electric Power Company Professor in Nuclear Engineering and professor of materials science and engineering, a team of researchers describe a new class of partially disordered rock salt cathode, integrated with polyanions—dubbed disordered rock salt-polyanionic spinel, or DRXPS—that delivers at high voltages with significantly improved cycling stability.

Humans with Intelligence Amplification IA and Artificial Intelligence AI

Posted by in categories: mobile phones, robotics/AI

Everybody is talking about Artificial Intelligence (AI). It is in our computers, services and even our mobile phones. The AI composes our messages, predicts our moves and even takes photos for us. Are we – humans – going to become “obsolete” in a matter of years?! Maybe there is a last chance – Intelligence Amplification (IA).

While an AI needs to be developed from scratch, we humans, already have great intelligence thanks to countless years of evolution. A modern human’s brain is an awesome tool!

Among us, there are some geniuses, but imagine if everybody can become one. And not just a genius, but a super-genius. Smarter than every person who has ever lived before! This is the idea behind Intelligence Amplification. To use our intelligence as a base and to add computers to make us smarter beyond our imagination. A hybrid, a work of art!

India will assemble iPhone 16 Pro for the first time

Posted by in category: mobile phones

Apple is continuing to expand manufacturing in India, and the country will reportedly produce the iPhone 16 Pro and iPhone 16 Pro Max as well as the regular models.

Originally, India only manufactured older iPhones, and then chiefly because it avoided import tax. More recently in its expansion of production in the country, India has taken on manufacturing current models of the iPhone 15.

According to Bloomberg, Apple intends to expand still further. For the first time, India will manufacture the iPhone 16 Pro and iPhone 16 Pro Max.

Molecular wires with a twist

Posted by in categories: computing, mobile phones, particle physics, quantum physics

From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists have been working on advanced materials based on carbon-based oligomer chains that can also conduct electricity. These include the organic light-emitting devices found in some modern smartphones and computers.

In quantum mechanics, electrons are not just point particles with definite positions, but rather can become ‘delocalized’ over a region. A molecule with a long stretch of alternating single-and double-bonds is said to have pi-conjugation, and conductive polymers operate by allowing delocalized electrons to hop between pi-conjugated regions – somewhat like a frog hopping between nearby puddles. However, the efficiency of this process is limited by differences in the energy levels of adjacent regions.

Fabricating oligomers and polymers with more uniform energy levels can lead to higher electrical conductivity, which is necessary for the development of new practical organic electronics, or even single-molecule wires.
