    THE AIMS OF THE RESEARCH Carbogenic nanoparticles or as loosely named in literature C-dots ,CDs, CQDs is a new rising star in the class of photo luminescent materials that were reported to be non- toxic and biocompatible. In terms of shape and internal structure they are largely considered to be quasi-spherical Nano- entities with diameter ranging from 3-30 nm. Their elemental content, C-dots characteristically contains a large amount of carbon (at least 44.50%), along with Hydrogen and Oxygen

    The Nothing that is about Everything The Nothing That Is A Natural History of Zero by Robert Kaplan is a book literally a book about the number zero and how it was formed. He takes the reader on a journey through time and shows the transformation of not just zero but numbers in general from multiple countries and empires. Kaplan starts off his book by describing zero and what its possibilities are in the world. Then he jumps into the Sumerians who were one of the first to create a number system

    I agree with this because water can turn into gas during the water cycle (Evaporation) while Oxygen and Hydrogen are already gasses. Compounds have the same properties as the materials which make them up. The properties that make up compounds are atoms of carbon, hydrogen/oxygen, etc. Compounds have properties that may be different from the properties of the elements in the compound. Compound is chemically joined and elements includes gases, liquid, ect. What is the difference between an element

    To quantify the electric field spread and penetration, Table I shows the percentage of volume of each brain tissue where the amplitude of E is greater than 50% of the peak of E in the cortex for each coil configuration. Due to the fact that different field distributions occur in the right and the left hemisphere of the brain tissues, percentage of volume of each brain tissue was calculated for both sides of the brain for HFA and HDA coils (double-cone and Halo coils are symmetric coils). HFA_R and

    Atoms in Electrons “Energy levels in Atoms exist all over the world. Some atoms consist of protons and neutrons making up a nucleus; they are surrounded by electrons. Rutherford made designs and conclusions to develop his nuclear atomic model. Although Rutherford’s model couldn’t explain other properties of elements, such as why metals or compounds of metals give off colors when the flame is heated” (Wilbraham et al 136). John Dalton. (Early nineteenth century) He combined an idea of elements with

    The element I chose to research is the element Titanium. Titanium’s symbol is Ti and is located Period and Group number four. Also, Titanium is considered a metal but does not have a group name. This element is usually found in the minerals rutile, ilmenite, and sphene. It also makes up 0.57% of Earth’s crust. When you look at Titanium’s physical data there are many components you have to look at. For instance, you have to look at it’s boiling and melting points. The boiling point is 3,287 degrees

    is a malleable, ductile, soft metal. It's located in period four and group two of the periodic table. Calcium atoms have 20 electrons and 20 protons, there are two valence electrons in the outer shells. Its mass number is approximately 40.08. Calcium has four stable isotopes including 40Ca, 42Ca, 43Ca, and 44Ca; 97% of naturally occurring calcium is in the isotope 40Ca. Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons. In nature, calcium does

    molecular geometries, and using the VSEPR model on a computer. The VSEPR Theory states that molecular geometries of molecules can be predicted through their number of electron pairs on the central atom because these electrons will repulse each other as much as they can while still being bound to the central atom. The Lewis Dot Structures and the molecular geometries that we were asked to draw were in order for us to have background knowledge of how each molecule was shaped before we had to make them on

    number for they will be the same. Because osmium has an atomic number of 76, it also has 76 protons. Unless an ion, the number of protons and electrons are the same. In other words, osmium has 76 positive charges atoms (protons), 76 negatively charged atoms (electrons) and 114 neutral charged atom (neutrons). This element can be found in period 6, meaning it has 6 orbitals for its electrons. In addition, this element lies with group 8, causing it to have the same number of valence electrons,electrons in
