Matter and antimatter II.

Let us also see some other examples. 1 A starving grizzly bear is able to kill a buffalo by itself, but wolves can do that only in a cooperating group (pack). Is it possible that there is something similar here? That it is either the collision of a pair with the same amount of energy…

Graphene dimensions

In my previous article, titled ”Brave new world” I wrote about the molecules that form while cutting graphene layers. Although I have defined a new group, namely minimal nano graphene ribbon in the group of minimal graphene ribbons, I had not gone further. Now, however I am going to define the full range of graphenes.…

“Brave new world”

Although the title refers to the famous novel of Aldous Huxley, but this really is a brave new world. In his lecture Tashiaki Enoki (“The Role of Edge Geometry and Chemical Structure in the Electronic Structure of Nanographene”, Nano Today 2013) described the physical and chemical effects of bisecting on graphene. He also told the…

Matter and antimatter

To our knowledge, every matter particle has its own pair of antimatter. When a  particle collides with its pair, they both get destroyed and change into photon, a neutral particle without mass. What is the explanation for there being much more matter than antimatter in the universe known by us, which may or may not…

Comparison of carbon dioxide reduction methods

1. THE CARBON DIOXIDE PROBLEM The concentration of carbon dioxide in Earth’s atmosphere is approximately 400 ppm in this year and rose by 2.0 ppm/yr during 2000-2009. This current concentration is substantially higher than the 280 ppm concentration present in pre-industrial times, with the increase largely attributed to anthropogenic sources. Carbon dioxide is a prominent…

PIN code protection

Since PIN code is a four digit number that many people can not memorize, therefore they write it down on a note. And because it is important that it is at hand, they place the note the to same place as they place their credit cards. That is why anybody who steals the credit card,…
