In this video, I demonstrate how to make an oxygen generator using manganese dioxide (MnO2) and hydrogen peroxide (H2O2) ...

This repository contains the Python version of Reaction Mechanism Generator (RMG), a tool for automatically generating chemical reaction mechanisms for modeling reaction systems including pyrolysis, ...

Food allergy symptoms can start quickly after eating and may last from minutes to a couple of days. Seasonal allergy symptoms can last for weeks or even months if exposure to the allergen continues.

Transfusion reactions are medical complications that arise after a blood transfusion. They may occur during the transfusion (known as acute) or weeks after it (delayed). They're further classified ...

Since iOS 17 and iPadOS 17, Apple has included Messages-like reactions in FaceTime that lighten up your video with visual effects. But rather than triggering them with words, you can trigger them ...

Abstract: The present paper illustrates a morphological evolution of Manganese dioxide (MnO 2) nanostructures by varying the reaction time of hydrothermal process. To establish the morphological ...

Bee, wasp, yellow jacket, hornet, and fire ant are the insect stings that most often trigger allergic reactions. But most people aren't allergic to insect stings and may mistake a normal sting ...

开发高性价比的质子交换膜(PEM)电解析氧反应(OER)电催化剂是实现大规模电解制氢的关键。在这里，我们提出利用化合物Er2O3来提高MnO2在酸性OER中的催化性能。原位拉曼和DFT计算表明，Er2O3不仅抑制了MnO2的相变，而且在界面处进行溶解，从而优化了活性催化层的 ...

Baked bread, roasted coffee, and grilled steak owe their enticing smell to a sequence of chemical reactions that was first reported 100 years ago by the French chemist Louis-Camille Maillard. Although ...

On March 11th, 2021, Fox News broadcasted United States President Joe Biden's speech in which he spoke about the passage of his $1.9 trillion COVID-19 stimulus package. The speech coincided with the ...
