Today, we’re excited to introduce Alexa+, our next-generation assistant powered by generative AI. ...

Aluminum coordination in the framework of USY and ZSM-5 zeolites containing charge-compensating cations (NH 4+, H +, or Cu +) was investigated by Al K-edge EXAFS and XANES. This work was performed using a newly developed in-situ cell designed especially for acquiring soft X-ray absorption data.

Alexa remembers your preferences to make the experience feel tailored to you. Find the name of that song you love, discover new favorite shows or recipes, have Alexa create unique bedtime stories, 2 view recaps of your team, and quickly reorder food from your go-to spots with Grubhub.

Get help and learn about all things Alexa, from device set-up, to using features and skills, to privacy settings and more. Let us help you personalize your Alexa experience and get more out of your Amazon Echo device, works with Alexa or Alexa built in devices.

The new Alexa is our next-generation AI assistant that gets thing done – Alexa+ solves daily problems, keeps you entertained, helps you learn, keeps you organized, summarizes complex topics, and can converse about virtually anything. Customers who own or purchase an Echo Show 8, 10, 15, or 21 are eligible for free early access.

Aluminium K-edge X-ray absorption near edge spectra (XANES) of a suite of silicate and oxides minerals consist of electronic excitations occurring in the edge region, and multiple scattering resonances at higher energies. The main XANES feature for four-fold Al is at around 2 eV lower energy than the main XANES feature for six-fold Al.

2018年7月31日 · With more than 500,000 K-edge X-ray absorption near edge (XANES) spectra for more than 40,000 unique materials, this database constitutes the largest existing collection of computed XAS spectra...

2025年3月2日 · The upgraded Alexa service will cost $19.99 a month or be free if you're an Amazon Prime member. It will officially roll out over the next few weeks and "subsequently in waves in the coming months ...

2018年3月20日 · In this work, we report the development of XASdb, a large database of computed reference XAS, and an Ensemble-Learned Spectra IdEntification (ELSIE) algorithm for the matching of spectra.

2025年2月26日 · Rumors about an AI enhancement to Alexa have been swirling around for a couple of years, but the rollout faced a severe setback in 2024. Beta testing at the time revealed that the new version of ...
