Compositional grading of colloidal quantum dots enables electrically driven amplification of light, bringing electrically driven lasers from these materials very close.

There is a new battery type being hyped, with terms such as “Quantum Glass” battery or even “The Jesus Battery” and a claim that “It Will Ignite the Global $3 Trillion Electric Car Revolution.” Go and see it for yourself at investorplace.com (video transcript available from me), Forbes, and other financial information services.
This touted breakthrough in battery technology is the latest in a slew of innovative ideas that include “batteries made with sand,” “stretchable batteries,” “foam batteries,” “pee powered batteries,” “laser-made micro-super-capacitors” and more (13 Amazing Battery Innovations That Could Change The World).
TOKYO — Toyota is ramping up electric vehicle deployment plans, pulling forward its goal of selling 5.5 million electrified vehicles by five years and aiming to develop a solid-state battery by next summer as it races to meet a “sudden surge” of EV popularization.
Toyota now aims to sell some 5.5 million traditional gasoline-electric hybrids, plug-in hybrids, EVs and hydrogen fuel cell vehicles by 2025. Nearly 1 million of them could be pure EVs.
Executive Vice President Shigeki Terashi, Toyota’s r&d chief, outlined the new roadmap in a June 7 briefing about the company’s EV plans. In December 2017, the company had said it wanted to sell that many electrified vehicles by 2030, five years later than the revised outlook.
Michelin and General Motors have teamed up to literally reinvent the wheel with a new generation of high-tech airless tires.
The automotive companies’ Uptis (Unique Puncture-proof Tire System) prototype grabbed headlines after it was presented at the Movin’On Summit on sustainable mobility in Montreal this week.
It doesn’t have a traditional sidewall and carries a load by the top via a resin-embedded fiberglass material that Michelin already has 50 patents for, according to Car and Driver.
Researchers have found a way to accelerate antimatter in a 1000x smaller space than current accelerators, boosting the science of exotic particles.
The new method could be used to probe more mysteries of physics, like the properties of the Higgs boson and the nature of dark matter and dark energy, and provide more sensitive testing of aircraft and computer chips.
The method has been modelled using the properties of existing lasers, with experiments planned soon. If proven, the technology could allow many more labs around the world to conduct antimatter acceleration experiments.
Tesla has just launched pricing and ordering for the Tesla Model 3 that will be made in the Shanghai Gigafactory. The 328,000 RMB ($47,475) price for the Standard Range Plus is before local incentives, and crushes fossil rivals in the same class and without somewhat similar specs, the BMW 3 Series and Mercedes C-Class (also both locally made in China).
