Alibaba’s Ele.me head to step down amid shift to younger leadership

a very solid browser by most standards.

ESA’s JUICE mission will insert itself into Jupiter’s orbit to explore the gas giant and its icy moons EuropaHow perovskite thin films enhance X-Ray detector sensitivityCurrent X-Ray detectors operate at either hard or soft energy levels.

while also possessing excellent electrical properties to result in X-ray detectors with high sensitivity factors that exceed 5 × 103 µ◂…▸ and 6 × 104 µC Gy−1 cm−2 within soft and hard X-ray regimes.This breakthrough in perovskite-based X-Ray detectors holds significant promise for a wide range of imaging applications.Study Abstract:Multi energy X-ray detection is critical to effectively differentiate materials in a variety of diagnostic radiology and nondestructive testing applications.

an X-ray detector based on solution-processed thin-film metal halide perovskite that overcomes these challenges is introduced.these present poor energy discrimination across the broad X-ray spectrum and exhibit limited spatial resolution due to the high thicknesses required for radiation attenuation.

said: “This work showcases that there’s a natural extension of perovskites into printed X-Ray detectors.

existing multi-energy X-Ray detectors made from silicon and selenium are limited in their energy sensitivity and spatial resolution.Chinese e-commerce giant Alibaba is joining forces with a rocket maker startup Space Epoch to test rocket-powered parcel delivery.

A lot of great things seem like a joke at first.according to a post on Space Epochs official WeChat account.

but that it still hopes to bring opportunities for both the traditional logistics industry and Chinas commercial space field through the experiments.expected to reach shoppers worldwide within an hour.
