Unlocking the secrets of chemical bonding with machine learning

Posted by in categories: chemistry, robotics/AI

A new machine learning approach offers important insights into catalysis, a fundamental process that makes it possible to reduce the emission of toxic exhaust gases or produce essential materials like fabric.

In a report published in Nature Communications, Hongliang Xin, associate professor of chemical engineering at Virginia Tech, and his team of researchers developed a Bayesian learning model of chemisorption, or Bayeschem for short, aiming to use to unlock the nature of chemical bonding at surfaces.

“It all comes down to how catalysts bind with molecules,” said Xin. “The interaction has to be strong enough to break some at reasonably low temperatures, but not too strong that catalysts would be poisoned by reaction intermediates. This rule is known as the Sabatier principle in catalysis.”

“It was a beautiful fireball”: Japan space capsule carrying astroid samples lands in Australia

Posted by in categories: materials, space

It’s only the second time pristine astroid material has been brought back to Earth.


A Japanese space capsule carrying asteroid samples landed in a remote area of Australia as planned Saturday, Japan’s space agency, JAXA, said.

Why it matters via Axios’ Miriam Kramer: It’s only the second time pristine asteroid material has been brought back to Earth. Sample return missions like this one are incredibly valuable to scientists.

Control the Mouse with your Head Pose using Deep Learning with Google Teachable Machine

Posted by in category: robotics/AI

This article was published as a part of the Data Science Blogathon.

Introduction

Hi, In this article, let us go over how you can create a Python program using Convolutional Neural Networks (Deep Learning) and a mouse/keyboard automation library called pyautogui to move your mouse/cursor with your head pose. We will be using pyautogui as it is the simplest available Python library to programmatically control the various components of your computer. More details on how to use this library mentioned below.
