zinc oxide particles. The clients has also asked for advice on the use of bag filters as a standalone system, or in conjunction with a cyclone separator system. The filtration system must have a collection efficiency of 95% of the zinc oxide particle from a gas flow at 1000°C and with a flow rate of 3820 (Nm^3)/hr. One of the most common particle filtration devices used amongst many industries is a cyclone separator. These simple devices use centrifugal force to separate larger particles from a…

the net counts of the beta- emitting radionuclide, 137Cs as a function of pulse height voltage. Within Figure 5.8, the majority of the counts reside in the low voltage region, below 25 mV. It is possible to discriminate the between the different particle types by virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that eliminates pulses from background and noise.…

Introduction Quantum dots (Q-Dots) is very small semiconductor particles that means it can be either conductors or resist electricity depending on the temperature and purity of the semiconductor. Q-dots range in size from 2-10 nm, so because of their small size, quantum mechanics governs the physics of the particles. The synthesis Q-Dots were first studied in 1982 by Efros and Ekimov, and then many developments have reported the synthesis of semiconductor nanoparticles.1 Q-Dots have unique…

wavelength, in the relationship: λ = h / p Where h is the Planck's constant This wavelength λ is called the de Broglie wavelength. The de Broglie hypothesis states that particles of matter also have wavelengths and can behave as waves, like photons .According to String ,both types of particles demonstrated the vibrating strings, but 50 years before. Here was de Broglie’s line of…

The moving particles in transverse waves travel at right angles to the direction of transverse. Some examples of transverse waves are light waves and radio waves. A longitudinal wave is also known as a compression wave. The moving particles move back and forth in the same direction as the wave. An example of this is a wave moving through a stretched out slinky. Image 1: There are two areas in a longitudinal wave, a compression, and a rarefaction. A compression is created when particles are…

and beta rays would bounce off off different atoms. Ernest was responsible for a remarkable series of discoveries in the fields of radioactivity and nuclear physics. Alpha and Beta rays set forth the laws of radioactive decay and identified alpha particles (helium nuclei). This would change science forever. Ernest conducted research that…

section will discuss capillary bridges in more detail. Capillary bridges are formed under the influence of capillary action, which will be discussed first. Also the forces caused by capillarity are briefly discussed. Next, the characteristics of the particles and their effect on the shape of the bridge are discussed. This is followed by the mechanism of capillary bridge breakup. Finally the process of capillary bridge formation by condensation is discussed. 2.1.1. CAPILLARY ACTION Liquids are…

Frequency The number of full waves that past a given point in a given time or time frame. Amplitude The distance between a wave’s equilibrium and peak- crest or trough. Transverse wave A wave where the vibrations of particles travel 90° to the direction of energy transfer Compression waves (also known as a ‘longitudinal wave’) A wave in which the direction of the vibration is the same to the of the energy transfer Medium (plural form: media) Matter in which a wave travels…

Nevertheless, the existence of dark matter has been widely accepted henceforth, and research into it is ongoing. Astronomers have recently discovered a galaxy without the existence of dark matter(Shelton). Dark matter cannot actually be seen or detected itself, but, as Zwicky found, it causes immense levels of gravity. This newly discovered galaxy has only the normal amount of gravity you would expect to find due to its stars, planets, and general cosmic junk, unlike every other galaxy we’ve…

wrong because the heat made the particles expand which lead to making the brass ball bigger. My second hypothesis was correct; I had thought the water would make the ball smaller and therefore fit through the hoop easier. The water cooled down the ball making the particles contract. When we tried to fit the ball through it went through with ease. b). I saw that the ball fit through the ring before we tried our experiment. Once we had put it over the fire the particles expanded, so then there…
