Scientists create ‘liquid crystal’ that gets THICKER when stretched

Posted by in categories: 3D printing, engineering

The discovery by researchers at the University of Leeds marks a major breakthrough which has eluded material scientists for more than 30 years.

The ‘auxetic’ stretching property, which is found in human tendons and cat skin, had only been recreated using conventional materials.

Henri Becquerel and the Serendipitous Discovery of Radioactivity

Posted by in categories: education, engineering, particle physics, transportation

Antoine Henri Becquerel (born December 15, 1852 in Paris, France), known as Henri Becquerel, was a French physicist who discovered radioactivity, a process in which an atomic nucleus emits particles because it is unstable. He won the 1903 Nobel Prize in Physics with Pierre and Marie Curie, the latter of whom was Becquerel’s graduate student. The SI unit for radioactivity called the becquerel (or Bq), which measures the amount of ionizing radiation that is released when an atom experiences radioactive decay, is also named after Becquerel.

Becquerel was born December 15, 1852 in Paris, France, to Alexandre-Edmond Becquerel and Aurelie Quenard. At an early age, Becquerel attended the preparatory school Lycée Louis-le-Grand, located in Paris. In 1872, Becquerel began attending the École Polytechnique and in 1874 the École des Ponts et Chaussées (Bridges and Highways School), where he studied civil engineering.

Harvard Scientists to Release Sun-Dimming Sky Chemical in 2019

Posted by in categories: climatology, engineering, military, sustainability

Critics say that geoengineering efforts are Band-Aid solutions that treat the symptoms of climate change instead of the cause: global carbon emissions. Jim Thomas, the co-executive director of an environmental advocacy organization called the ETC Group, told Nature that he fears the Harvard project could push the concept of geoengineering into the mainstream.

But advocates say that anything that could buy some extra time in the face of looming climate catastrophe is worth exploring.

“I’m studying a chemical substance,” Harvard researcher Zhen Dai told Nature. “It’s not like it’s a nuclear bomb.”

Supersonic air travel is finally coming back

Posted by in categories: engineering, ethics, policy, transportation

Supersonic air travel is back. 15 years after the Concorde was grounded, everyone from aerospace companies to NASA to small startups is working to bring back ultrafast civilian aircraft. We take a look at the engineering challenges that make supersonic flight so difficult, and try to figure out what’s different about this new generation of planes.

Hydrogel-based electrodes for brain implants developed

Posted by in categories: biological, engineering, neuroscience

Hydrogels are physical and chemical polymer networks capable of retaining large quantities of liquid in aqueous conditions without losing their dimensional stability. They are used in a whole host of applications, and in combination with other components and they acquire specific properties such as electrical conductivity. The Materials + Technology research group in the Department of Chemical Engineering and Environment of the UPV/EHU’s Faculty of Engineering selected a biopolymer that had not previously been used for applications of this type: starch. “One of our lines of research focuses on starch, and we regard it as having biological, physical and chemical properties suitable for producing hydrogels,” said Kizkitza Gonzalez-Munduate, a member of the group.

New catalyst material produces abundant cheap hydrogen

Posted by in categories: chemistry, energy, engineering, government, sustainability

QUT chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.

Professor Anthony O’Mullane said the potential for the chemical storage of renewable energy in the form of hydrogen was being investigated around the world.

Elon Musk says there’s a 70% chance he’s going to move to Mars

Posted by in categories: climatology, Elon Musk, engineering, habitats, space travel

Elon Musk wants humans to make it to Mars. With his company SpaceX at his back, he’s pushed forward with some incredibly bold claims about what is possible for mankind on the Red Planet. He’s shown off concepts for Mars settlements and even called out scientists who say climate engineering on the planet is impossible.

Now, in an interview with HBO’s Axios, Musk doubles down on one of the more off-the-wall claims he’s made during his years in the spotlight. Mars, he says, will be his eventual home, and he estimates his odds of moving to the planet at a generous 70%.

AI heralds new frontiers for predicting enzyme activity

Posted by in categories: biological, chemistry, engineering, robotics/AI

Researchers from the Departments of Chemistry and Engineering Science at the University of Oxford have found a general way of predicting enzyme activity. Enzymes are the protein catalysts that perform most of the key functions in Biology. Published in Nature Chemical Biology, the researchers’ novel AI approach is based on the enzyme’s sequence, together with the screening of a defined ‘training set’ of substrates and the right chemical parameters to define them.
