    and shot a stream of electrons across the glass tube. When the particles stuck to the other end of the tube, it created a patch of light that indicated where the particles landed. Thompson discovered that by using a magnetic field, he could move and deflect particles. He found that particles would always move towards the positively charged side. By using a Cathode Ray Tube, Thompson was able to conclude that some particles are negatively charged; therefore, discovering electrons. Thompson 's…

    As people decided to sending human into deep space to explore unknown feature of the universe, the environment outside the earth is a big uncertainty with factors that we can’t fully understand yet. Besides the cost and the time we spend during long space travel, stay in the cold, vacuum universe would let astronauts experience different kind of radiation. These radiation may be some ionized particles as electromagnetic waves traveling with high speed and energy. They could come from nearby…

    – equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…

    Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

    and also it was an astronomical discovery 2. Statement 3 “Phosphorus = Hesperus” is a trivial statement that can be understood without any logic work at all. The two statements are particularly interesting because although statement one is referring to one object and statement two is referring two objects but in fact they are referring to the same identical object. What Frege was able to take away from this argument is that each singular term can have multiple understandings. Ferge proposed two…

    This means, in this scenario the electron motion is diffusive and green functions are nearly isotropic. Usadel’s approach not only deals to ‘strongly dirty’ samples but also ‘moderately dirty’ samples. The theory of upper critical field for MgB2 was developed separately by Alex Gurevich…

    temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal atoms act as charge carriers reservoir supply the complex with the free electrons and the metal ion can act as a bridge to facilitate the flow of current. To illustrate the effect of the metal type on the electrical resistivity of the ligand, isothermal…

    1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…

    Fig.7, shows that, the insulator behavior of the PVA for pure PVA. But, with increasing the time of reaction there is an improvement in the electrical conductivity of the PVA-Ag nanocomposite films. Fig.7 shows that, the (I–V) characteristic of the samples, and the inset of Fig. 7 shows the relation between the conductivity and time of reaction. Then, the dc conductivity was calculated at the (voltage = 10 V) using the relation. (S/cm) Where (d) is the sample thickness, (A) is the area of…
