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

Abstract: Popcorning is a well-known effect in plastic encapsulated microcircuits (PEM) and it occurs in chip tantalum capacitors. The sensitivity of components to the presence of moisture during ...

Abstract: In this article, the electrochemical monitoring of phenol (Ph) in water by using a nanostructured MnO2-modified screen-printed carbon electrode (MnO2-SPCE) is reported. MnO2 nanoparticles ...

In a recent article published in Coatings, researchers from China investigated the synthesis and photocatalytic properties of bamboo-like MnO₂/TiO₂ nanotube arrays (NTAs). The study highlighted the ...

Recently, the research team of Prof. Xiaohui Li at Shaanxi Normal University fabricated a section of γ-MnO 2 dual-core double-hole fiber by combining γ-MnO 2 with a special fiber, a dual-core ...

Increasing development of micro-scale electronics has stimulated demand of the corresponding micro-scale power sources, especially for micro-batteries (MBs). However, complex manufacturing process and ...

Scientists at Tokyo Tech have developed and analyzed a novel catalyst for the oxidation of 5-hydroxymethyl furfural, which is crucial for generating new raw materials that replace the classic ...

Catalysis of the decomposition of hydrogen peroxide is demonstrated in a foil-covered florence flask or fancy bottle. A packet of manganese dioxide catalyst is suspended by a thread inside the neck of ...
