55 years ago, the ‘Mother of All Demos’ foresaw modern computing

Posted by in categories: computing, engineering, food, sustainability

Engelbart grew up on a small farm in Southeast Portland where his father operated a radio store.

He graduated from Franklin High School in 1942 and enrolled at Oregon State College, now called Oregon State University, to study electrical engineering.

When World War II interrupted his studies, he spent two years working as a Navy radio and radar technician in the Philippines.

These Superconductors Are Acting “Strange,” and Scientists Finally Know Why

Posted by in categories: quantum physics, sustainability

Recent research has unlocked key aspects of high-critical-temperature superconductors, identifying their unique ‘strange metal’ state and a crucial quantum critical point. This discovery, resulting from collaborative efforts and extensive experiments, paves the way for advanced superconducting technologies.

Taking a significant step forward in superconductivity research, the discovery could pave the way for sustainable technologies and contribute to a more environmentally friendly future.

The study just published in Nature Communications by researchers from Politecnico di Milano, Chalmers University of Technology in Göteborg, and Sapienza University of Rome sheds light on one of the many mysteries of high-critical-temperature copper-based superconductors: even at temperatures above the critical temperature, they are special, behaving like “strange” metals. This means that their electrical resistance changes with temperature differently than that of normal metals.

Newly created ultra-hard material rivals diamond

Posted by in categories: solar power, space travel, sustainability

Potentially very useful discovery.

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond as the hardest material on Earth. The research is published in the journal Advanced Materials.

Researchers found that when carbon and nitrogen precursors were subjected to and pressure, the resulting materials—known as carbon nitrides—were tougher than cubic boron nitride, the second hardest material after diamond.

The Emergence Of Smart Cities In The Digital Era

Posted by in categories: internet, nanotechnology, robotics/AI, security, sustainability, wearables

By Chuck Brooks

Realizing the potential of Smart Cities will require public-private cooperation and security by design.

The idea of smart cities is starting to take shape as the digital era develops. A city that has developed a public-private infrastructure to support waste management, energy, transportation, water resources, smart building technology, sustainability, security operations and citizen services is referred to as a “smart city”. Realizing the potential of Smart Cities will require public-private cooperation and security by design.

What To Know About Where ChatGPT Is Going In 2024

Posted by in categories: business, education, ethics, robotics/AI, sustainability

It’s hard to believe, but generative AI — the seemingly ubiquitous technology behind ChatGPT — was launched just one year ago, in late November 2022.

Still, as technologists discover more and more use cases for saving time and money in the enterprise, schools, and businesses the world over are struggling to find the technology’s rightful balance in the “real world.”

As the year has progressed, the rapid onset and proliferation has led to not only rapid innovation and competitive leapfrogging, but a continued wave of moral and ethical debates and has even led to early regulation and executive orders on the implementation of AI around the world as well as global alliances — like the recent Meta + IBM AI Alliance — to try and develop open frameworks and greater standards in the implementation of safe and economically sustainable AI.

Power Play: How Electrochemistry Is Winning the Green Game

Posted by in categories: chemistry, economics, energy, sustainability

New research on electrochemical reactions highlights the critical role of electrolyte ions, aiding in the advancement of sustainable energy technologies.

Electrochemical reactions are central to the green transition. These reactions use the electric current and potential difference to carry out chemical reactions, which enables binding and realizing electric energy from chemical bonds. This chemistry is the basis for several applications, such as hydrogen technology, batteries, and various aspects of circular economy.

Developments and improvement in these technologies require detailed insight into the electrochemical reactions and different factors impacting them. Recent studies have shown that besides the electrode material also the used solvent, its acidity, and the used electrolyte ions crucially impact the efficiency of electrochemical reactions. Therefore, recent focus has shifted to studying how the electrochemical interfaces, i.e. the reaction environment at the electrode and the electrolyte interface shown in Figure 1, impact the outcome of electrochemical reactions.

Researchers Use Molecular Engineering To Improve Organic Solar Cell Efficiency

Posted by in categories: engineering, health, solar power, sustainability, wearables

Polymer solar cells, known for their light weight and flexibility, are ideal for wearable devices. Yet, their broader use is hindered by the toxic halogenated solvents required in their production. These solvents pose environmental and health risks, limiting the appeal of these solar cells. Alternative solvents, which are less toxic, unfortunately, lack the same solubility, necessitating higher temperatures and prolonged processing times.

This inefficiency further impedes the adoption of polymer solar cells. Developing a method to eliminate the need for halogenated solvents could significantly enhance the efficiency of organic solar cells, making them more suitable for wearable technology.

In a recently published paper, researchers outline how improving molecular interactions between the polymer donors and the small molecule acceptors using side-chain engineering can reduce the need for halogenated processing solvents.
