Floating charge

batteries, an even your home. "Energy Story" also talks about how all matter is made up of atoms, and that atoms are made of smaller particles. In the story "Conducting Solutions" it talks about how an electric current is a flow of electrical charge. The story also talks about electrons are subatomic particles with…

Most antimicrobial peptides contain well-defined cationic domains and display a net positive charge ranging from +2 to +9. Cationicity is important as it influences the degree of electrostatic attraction of antimicrobial peptides towards negatively charged phospholipid membranes of bacteria and other microorganisms. Consequently, the polycationic…

Observing the advance, General Hunt ordered his batteries into action. This time the artillery was employed with deadly precision and effect on target. Delivering multiple Confederate wounded or dead with each round of Grape Shot fired. The effects of accurate artillery fire combined with the terrain began to close the 400 yard gap between General Pickett and General Pettigrew. With the bunching up of troops in General Pickett’s and General Pettigrew’s Divisions, General Hunt’s artillery was all…

The Chemistry of H2O. Principles of the Octet Rule, Electronegativity, Polarity, Density, and their effect on H2O Aryeh L. Strauss Suny Rockland Atoms are made up of protons, neutrons and electrons. Protons have a positive charge and electrons have a negative charge (neutrons are neutral). The protons are in the nucleus of the atom and the electrons fill shells surrounding the nucleus. The shells closest to the nucleus have the lowest energy level and the shells furthest away have the…

pristine (C60)2 fullerene. In Fig.7 the transmission function curve of (C59N)2 molecule is indicated. It is seen that a high transmission peak is formed at the Fermi level. Because the LUMO level of each C60 molecule is partially filled due to the excess charge of N atom.One might expect that the current increase meaningfully with B:B doping as well as N:N doping.Because B atom has one less electron than C atom, therefore doping one B atom…

about electric chargers that do not move. Static electricity is one of the many things that are covered in electrostatics. An object that has accumulated electric charge has static electricity (“Electricity for kids”, 1). The charges are not on the move nor do they flow from one place to another. It is easy to remember that the charges don’t move in static electricity, because static can be tied to the word stationary. The word stationary means that an object does not change its position and…

opposite of an electron or antielectron is a positron it has a positive charge. Protons and neutrons help classify atoms and elements. Atomic number is the amount of protons, it also is the amount of electrons. Atomic mass is the amount of protons and neutrons. Leptons are half-integers spin that does not undergo many interactions. There are two types, ones with negative charges, like electrons, and ones with a neutral charge, like neutrons. These are a type of antimatter. Usually atoms are…

particles collide, they build up large electrical fields in the clouds. A “spark” occurs whenever these electric fields become large enough to produce static electricity. The static electricity reduces the charge separation. The spark made…

with positive and negative charges. JJ Thomson (1856-1940), taking and perfecting this knowledge with his experiment, is recognized with calculating the ratio of electron charge to mass and the first model of atomic structure to account for the positive and negative sub-particles. Thomson measured the amount of magnetic force needed to exactly counterbalance the deflection of a strong beam of electrons projected between charged plates. He used this to find the ratio of charge to mass of an…

One of my favorite philosophers in Sophie's World was Democritus. Democritus discovered atoms, tiny invisible blocks he thought that everything was made of; eternal and immutable. Democritus was also a materialist, someone who believes that nothing exists but physical matter. The philosopher, Alberto Knox, has asked Sophie “Why is Lego the most ingenious toy in the world?” The next day, he sends her a green packet talking about Democritus. Lego blocks are a great deal like atoms. Democritus…
