Numerical simulationFinal report: Comparison simulation data of Si4N3 dielectric material(doi: 10.17188/1197656)I. IntroductionSilicon nitride (Si3N4) is a non-metallic compound composed of silicon and nitrogen. This material is interesting because of its durability, electrical insulation, high thermal stability and high acid resistance that widely used in microelectronics and micro-surface machining technologies.The micro-bolometer devices were fabricated at nano and energy center (NEC) of Vietnam national university (VNU) used Si3N4 shut as a supporting layer for the suspending structure and in absorption infrared radiation (IR) packet. The fabrication method used plasma enhanced chemical vapour deposition (PECVD) system that require high vacuum. The optimization of IR absorption packet by experimental is extremely expensive. Thus, the properties of Si3N4 crystal structure need to investigate by simulation and compare to experiment data.

Please help me write a report focusing on “photocatalysis of TiO2 material”. Most of the papers regarding this topic can be found online.Requirement:- 8 to 10 pages long- Does not have to be strictly plagiarism free (you can pick certain ideas from certain paper and lightly paraphrase their idea. You can just copy paste their images if they have any)

Question 1: In the “Introduction” section (second paragraph), they claim that strong linear absorption in the OPA technique makes this only usable for 2D scanning and the absence of linear absorption in TPA technique and local non-linear absorption makes this technique applicable for 3D scanning. Please explain and elaborate this idea with graph and/or equation.Question 2: In the “Working principle of LOPA microscopy” section, they wrote: “The intensity increases nonlinearly and reaches a maximum value at the focal plane ” (line 2 and 3). Please explain and elaborate this idea with drawing and/or equation.Question 3: In the “Working principle of LOPA microscopy” section, from line 1 to 6 at page 4, they imply that the high absorption of OPA decreases the intensity of light and this is a disadvantage of OPA technique and it hinders the the OPA technique from achieving what the TPA technique can do (being able to give off light with high intensity and get photo induced effect). However, at line 8 to 11 they claimed that the strong linear absorption of OPA technique can also get photo induced effect ? Can you elaborate on this idea ? i think im misunderstanding somethingQuestion 4: In the “Working principle of LOPA microscopy” section, paragraph 2 (from line 12 page 4). They are explaining on how they get low absorption effect with OPA. I don’t understand this at all. Can you explain this with drawing and/or equation ? thank you.Question 5: In the “Working principle of LOPA microscopy” section, paragraph 2, line 7 to 9 they wrote ” Although the absorption is ultra weak, the effective photo induced effect in focusing region is therefore comparable to that obtained by a laser beam with a high absorption effect”. I do not understand this point at all because i thought the whole point of this is making OPA having low absorption like the TPA technique so this OPA technique can do what the TPA technique can too. Why are they speaking of the “high absorption effect” as an advantage now ? What am i misunderstanding

1. Using Equation 4.4, show that d represents the mean distance neutrons travel before being absorbed.25. If you were located 100 km from a 1 GW nuclear power plant, what would the neutrino flux be at your location? Assume that a 1 GW nuclear power plant releases 1021 neutrinos per second and you present a 1 m2 surface to the neutrino flu

1. Use the information in Section 6-1 and write a summary of the Nice model of how the solar system formed. Explain how the solar nebula collapsed, how the protosun formed, how the planetary disk formed, the role of temperature at different locations of the solar system (i.e the snow line & how it relates to what substances were found on either side of it), and the role of collision & accretion in forming the planetesimals. This question is worth up to 10 points.2. Use the information in Section 6-2 to summarize how each of these planets formed: Jupiter, Saturn, Uranus, and Neptune formed. Include information about what they are made of and why, the order in which they formed, and where they formed (5 points)3. Use the information in Section 6-3 to summarize how the inner planets formed. Include information on what they are made of as compared to the outer planets, and where their water came from. (5 points)4. Use the information in Section 6-11 and describe the general pattern of orbital size, planet size, and density across the solar system. Also describe the planetary debris (comets, asteroids, meteoroids) and dwarf planets in our solar system including where we would find them and what they are made of. (5 points)5. Use the information in Section 6-12 and compare/contrast the planets in our solar system to planets in other system in terms of their size/density, masses, orbits, age, etc (5 points)Make sure your answers are focused on what is being asked in each question and that the answers are in-depth with lots of relevant details.

Thinking about the idea of attention as a limited, valuable resource, provide an example of the issue that Dr. Wu brings up in the video that you have experienced in your life.
