Predicting the slow death of lithium-ion batteries

Energy-daily.com 

Stanford CA (SPX) Sep 15, 2020 - Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it's next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to manage charge levels wisely and to estimate driving range in electric cars are nearly blind to changes in the battery's internal workings.

Instead, they operate more like... Читать дальше...

Energy harvesting goes organic, gets more flexible

Energy-daily.com 

Washington DC (SPX) Sep 16, 2020 - Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural biocompatible piezoelectric materials for energy harvesting, electronic sensing, and stimulating nerves and muscles.

University College Dublin and University of Texas at Dallas researchers decided to explore peptide-based nanotubes, because... Читать дальше...

Jets obliterated by 49ers in another embarrassing loss

New York Post (sports) 

The Jets’ “brilliant offensive mind” and their “dominant” defense have a lot work to do. The injury-depleted 49ers blew away Gang Green in the Jets’ home debut, treating Adam Gase’s team like an ill-equipped sparring partner that didn’t belong in the same ring. From the game-opening 80-yard touchdown run by Raheem Mostert to Jerick McKinnon...

Govt pushes through farm bills amid opposition charges of foul play

Timesofindia.indiatimes.com (sports) 

Amid unruly and aggressive protests by opposition members, the Rajya Sabha on Sunday passed by voice vote two contentious farm bills that were earlier approved by the Lower House. The two bills will now be sent to the President for his assent. The bill was opposed by BJP's estranged ally, the Shiromani Akali Dal, TRS and BJD which, in a rare instance, decided to vote "no".

49ers blast Jets 31-13, but lose Garoppolo, Bosa, Mostert

Washingtontimes.com (sports) 

EAST RUTHERFORD, N.J. (AP) - Raheem Mostert ran for an 80-yard touchdown on San Francisco's first play from scrimmage and Jimmy Garoppolo threw two TD passes - before both players sat out the second half with injuries - and the banged-up 49ers rolled past the inept New York Jets 31-13 ...

Single photons from a silicon chip

Spacedaily.com 

Dresden (SPX) Sep 16, 2020 - Quantum technology holds great promise: Just a few years from now, quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee absolutely secure data transfer, albeit with limitations.

The greatest possible compatibility with our current silicon-based electronics will be a key advantage. And that is precisely where physicists from the Helmholtz-Zentrum Dresden-Rossendorf... Читать дальше...

Neutron stars contribute little, but something's making gold

Spacedaily.com 

Spotswood, Australia (SPX) Sep 16, 2020 - Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds. The research also reveals that current models can't explain the amount of gold in the cosmos - creating an astronomical mystery.

The work has produced a new-look periodic table, showing the stellar origins of naturally occurring elements from carbon to uranium.
