The objective of this presentation is to provide an overview of the methodology employed in patent landscape analyses (PLA), with a particular focus on the patented processes used to produce hydrogen peroxide. Patents are an essential source of technical knowledge that may not be found anywhere ...
The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
That might sound weird, but it's just the way the chemistry plays out: dissolved CO2 molecules combine with water to form what's called carbonic acid, which in turn combines with carbonate to form hydrogen carbonate.可能有点危言耸听，但这是化学物质本身的特性所造成的，溶解的二氧化碳与水结合形成...
Will you be able to find a hydrogen fuelling station to refill your tank? And, perhaps most importantly, as a fuel, is hydrogen really as non-polluting as it seems? We'll look at those questions in the pages that follow, but we can give you one quick answer right now: Unless you ...
The reason that argonium can exist in the Crab Nebula is that electrically-charged cosmic rays passing through space strip argon atoms of an electron, allowing it to bond with hydrogen. Researchers also discovered that argonium is created from a different isotope of argon than the one in Earth...
Want to know more? Read on to find out more about how hydrogen is used as a fuel source. Hydrogen as a power plant fuel In the face of the intensifying climate crisis, hydrogen has emerged as a potential alternative to polluting fossil fuels like coal and oil. In theUnited States,...
1. Could you share insights into your role in blue hydrogen technology licensing? The blue hydrogen project demonstrates how Shell applies traditional technologies to find solutions for the energy transition. Since the 1950s, Shell developed valuable gasification technology ...
How to Find Oxidation NumberThe oxidation number of an atom in an ion or compound can be determined using the above rules. Let us look at a few examples [1-6].1. Sulfuric Acid (H2SO4)The oxidation number of hydrogen (H) and oxygen (O) are +1 and -2, respectively. Sulfuric acid...

evidence to tell us what the common physical characteristics for sub-Neptunes are,” said Hu. “Many of them may have massive hydrogen atmospheres, but quite a few could still be ‘ocean planets.’ I hope this paper will motivate...
