In the paper, FePO4 was studied in through neutron powder diffraction across a wide range of temperatures, and was found to have 2 states in general, the α (alpha) phase and β ( beta ) phase. The alpha phase exhibits a tetrahedral structure, which is similar to alpha quartz, and this occurs during generally low temperatures. In the case of this paper, the temperatures experimented on were between 294K and 1073K. The beta phase, however, is denser and exhibits a octahedral structure. The…

the figure (7c) the superior electrochemical performance is due to the synergetic effect between conductive GO or BGN and NCA-L-NF when compared with pure NCA-L-NF. 9 It may be attributed to GN/BGN in the electrode convey a conductive network for electron transportation during redox reaction.because of the presence of numerous nanochannels, also the unique morphology of BGN–LTH acts as a perfect reservoir to facilitates enhanced contact, diffusion as well as penetration of OH-ions for highest…

The FTIR spectrum of PVA/CS nanofiber was shown in Fig. 1(a). The band at 3255.32 cm−1 was corresponded to -OH stretching and the peaks at 1025.6 and 1450.04 cm−1 for the -C-O band. The peaks at 3445.32 cm-1, 2965 cm-1, 1640.01cm-1, 1598.7 cm-1, and 1361 cm-1 are due to amine NH symmetric vibration, C-H vibration, deformation vibration of the absorbed water molecules, stretching vibration of amino group of chitosan and vibration of C-H, respectively. The peaks at 890.1 and 1100 cm-1 was…

I argue that many different branches of science are reducible to one fundamental one- physics. In this essay, I will use Pasteur’s work to demonstrate that biology and chemistry are reducible to physics - the study of interactions between matter and energy. By reducible, I mean that these sciences (and other hard sciences) can be simplified to the point where they deal with the same fundamental matters as physics. During the 1700s, chemists engaged in a long-standing debate over what caused…

has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. What happens is the solution of the water and the salt is transformed…

is 40.078 u. Family. The periodic table is classified into groups and every group(row) has its own properties. Calcium is in group 2 ,and this is the second most reactive group of the periodic table. Each of the elements in group 2 has two electrons in their outer shell. “This group is called Alkaline Earth metals, they are called this because when they are mixed in solutions, they are likely to form solutions with a Ph greater than 7.” Metal, nonmetal or metalloid?…

occur, known as plastic deformation. The hardening of materials through the use of deformation in a material stems from the atomic structure of a metallic material. Metals are held together by metallic bonding where electrons are shared amongst atoms so that a "sea" of electrons is created. This type of bonding is not only strong enough to keep the atom together, but because of a lack of bond directionality, dislocations are able to be created and moved without the entire molecule falling…

Chromium Chromium was discovered in France in 1797. A man named Louis-Nicholas Vauquelin discovered chromium while experimenting with a material known as Siberian red lead. The name Chromium comes from the Greek word "chroma" meaning "color." Chromium got this name because of the many different colors in the element. This element is hard, metallic and shiny. Chromium doesn't tarnish. Chromium is a metal element. Chromium's symbol is "Cr" and has an atomic number of 24. This metal is the…

The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be…

Albert Einstein's influence on astronomy. Albert had a big influence on Astronomy. He started to study mathematics, he was lured toward calculus around 1891. Albert originally wanted to be a electrical engineer. But he failed to do pass an examination which would have allowed him to study for a diploma at the Eidgenössische Technische Hochschule in Zurich. He made a plan of graduating as a teacher in mathematics and physics. He got his PHD in 1905. He also created the theory of relativity. A…
