Evaluation and analysis of the latest ten air fryers, multi-dimensional evaluation of heating/odor/materials!
I had long wanted to create an air fryer evaluation and analysis report. Previously, I wrote several popular science articles about air fryers, which led many users to ask how to choose an air fryer without stepping into the trap? Especially how to avoid the safety, irritating odor, and high temperature resistance issues that exist in air fryers? So today we will conduct a multi-dimensional evaluation and analysis of air fryers based on the popular models on the market! Avoid potential hazards caused by blind and random purchases by everyone!This issue of air fryer evaluation is presented by comparing scientific evaluation methods with completely authentic results,Overview of air fryer models participating in the evaluation:Air fryer evaluation dimension one: heating efficiencyThe heating efficiency of an air fryer can be said to be a key factor in determining the cooking speed! High heating efficiency means that the internal center temperature quickly rises to a stable working temperature, which is equivalent to giving a fryer an accelerator to quickly preheat and start frying delicious food...

Hard carbon negative electrode materials make energy storage a "rookie"?
Reporter Li He from our newspaperHard carbon is a type of carbon that does not undergo graphitization after high-temperature treatment. Its internal crystal arrangement is disordered and the interlayer spacing is large, which allows the hard carbon negative electrode to store more charges at the same volume, improving the energy density and endurance of sodium ion batteries...

Metal Magic: Creating Dream Materials with Semiconductor Quantum Dots
Science and Technology Daily, Beijing, May 30 (Reporter Zhang Jiaxin) According to the latest issue of Nature Communication, a team including researchers from Japan's RIKEN Emerging Materials Science Center has successfully created a "superlattice" composed of lead sulfide semiconductor colloidal quantum dots, in which researchers have realized the conductivity of similar metals, which is 1 million times higher than the current quantum dot displays, And it will not affect the quantum confinement effect. This progress may completely change quantum dot technology, enabling new applications in electroluminescent devices, lasers, thermoelectric devices, and sensors...
