How the operating window of LFP/Graphite cells affects their lifetime
Eniko Zsoldos. Eniko Zsoldos is a 5th year PhD candidate in chemistry at Dalhousie University in the Jeff Dahn research group. Her current research focuses on understanding degradation mechanisms in a variety of lithium-ion cell chemistries (NMC, LFP, LMO) using techniques such as isothermal microcalorimetry and electrolyte analysis.
Do atoms going through a double slit ‘know’ if they are being …
May 26, 2015 · Does a massive quantum particle – such as an atom – in a double-slit experiment behave differently depending on when it is observed? John Wheeler’s famous “delayed choice” Gedankenexperiment asked this question in 1978, and the answer has now been experimentally realized with massive particles for the first time. The result demonstrates that it does not make sense to decide whether a ...

Setting the scale: the life and work of Anders Celsius
Dec 4, 2024 · Object of precision The original Delisle thermometer that Celsius marked with his 100-degree scale. (Courtesy: Museum Gustavianum, photograph by Mikael Wallerstedt) On Christmas Day in 1741, when Swedish scientist Anders Celsius first noted down the temperature in his Uppsala observatory using his own 100-point – or “Centi-grade” – scale, he would have had no idea that this was to be ...
Return to Helgoland: celebrating 100 years of quantum mechanics
Dec 1, 2024 · A new dawn It was on the island of Helgoland off the coast of Germany in June 1925 that Werner Heisenberg created matrix mechanics. (Courtesy: iStock/Iurii Buriak) At 3 a.m. one morning in June 1925, an exhausted, allergy-ridden 23-year old climbed a rock at the edge of a small island off the coast of Germany in the North Sea.

Lithium-ion batteries break energy density record - Physics World
Apr 21, 2023 · Lithium-ion batteries recharge in the cold. The researchers, who report their work in Chinese Physics Letters, explain that a trade-off always exists between the energy density, cycle performance, rate capability and safety of lithium-ion batteries.Safety is a primary requirement, but elevated energy density will increase the risks during battery operation, they say.
