Researchers build a quantum dot energy harvester

Posted by in categories: nanotechnology, quantum physics, robotics/AI

Over the past few years, thermoelectric generators have become the focus of a growing number of studies, due to their ability to convert waste heat into electrical energy. Quantum dots, semiconductor crystals with distinctive conductive properties, could be good candidates for thermoelectric generation, as their discrete resonant levels provide excellent energy filters.

In a recent study, researchers at the University of Cambridge, in collaboration with colleagues in Madrid, Rochester, Duisburg and Sheffield, have experimentally demonstrated the potential of an autonomous nanoscale harvester based on resonant tunneling quantum dots. This harvester is based on previous research carried out by part of their team, who had proposed a three-terminal energy harvester based on two resonant-tunneling quantum dots with different energy levels.

The energy harvester device was realized at Cavendish Laboratory in Cambridge by a researcher called Gulzat Jaliel. The original theoretical proposal for the device, however, was introduced by Andrew Jordan in 2013, and the theoretical work behind the harvester was carried out by him in collaboration with renowned semiconductor physicist Markus Büttiker and a team of post-doctoral students in Geneva.

Can you wear that on Mars?

Posted by in category: space travel

If you can’t get to Mars, what’s the next best thing? Apparently Iceland. A team of renowned explorers and researchers recently journeyed to Iceland to test a Mars analog suit in a Martian-like environment.

The United sponsored expedition, led by The Explorers Club — an internationally recognized organization that promotes the scientific exploration of land, sea, air and space — and in partnership with Iceland Space Agency, involved the team venturing inside the Grímsvötn volcano and across the Vatnajökull ice cap. The group traveled to the remote location and lived for six days in the Grímsvötn Mountain Huts and endured harsh weather conditions and unstable terrain.

Lunar Polar Mining Technology

Posted by in category: space

≈2 km craters near the lunar poles provide landing sites on permafrost with permanent sunlight low enough to reach with solar arrays on deployable masts. Radiant Gas Dynamic (RGD) mining in small polar craters will allow human exploration of the Moon at vastly reduced cost. RGD mining combines radio frequency, microwave, infrared, and optical radiation with a surface-enclosing cryotrap and instrumentation to enable large scale (1,000s of tons/yr) ISRU without excavation equipment.

The future of food: what we’ll eat in 2028

Posted by in categories: food, robotics/AI

We’ve all heard that the future menu may involve less meat and dairy. But don’t worry, we could have customised diets, outlandish vegetables, robot chefs and guilt-free gorging to look forward to instead. And we reckon that makes up for missing out on the odd sausage.

We’re continuing to release talks from Ending Age-Related Diseases 2019, our highly successful two-day conference that featured talks from leading researchers and investors, bringing them together to discuss the future of aging and rejuvenation biotechnology.

Dr. Greg Fahy of Intervene Immune gave a presentation about his company’s Phase 1 human trials in which the thymus, a critical organ of the immune system, was regenerated through a combination of existing drugs, restoring immune function and causing epigenetic biomarkers to show rejuvenation.

Nanochains could increase battery runtime and speed charging

Posted by in categories: computing, mobile phones

Researchers at Purdue University have announced a breakthrough that could have a significant impact on batteries of the future. The team says that the runtime for the battery in a phone or computer depends on how many lithium-ions can be stored in the negative electrode material inside the battery. When those ions are depleted, the battery is unable to deliver an electrical current.
