In this study, the effect of benzenethiol ligand on CdSe/ZnS core/shell quantum dots was investigated. Conventional long-chain oleic acid (OA) and trioctylphosphine (TOP) capping ligands were partially replaced by short benzenethiol ligands, and the improvement in the luminescence performance was observed in quantum dot light emitting diodes (QD-LED). Approximately 1.8 fold improvement was achieved for both the maximum luminance and maximum current efficiency for the QD-LEDs fabricated with…

problem is? Your answer to that is a Automotive Mechanic! the career of Auto Mechanics is an interesting career because of the things you are able to learn and do. The research will describe the career of Mechanics and the impact it has on society and topics dealing with this career. Before cars were made people traveled by horses. when vehicles were made and were available just before the beginning of the 1900s car owners went to bicycle mechanics or blacksmiths to repair or fabricate parts …

Plato once said, “Astronomy compels the soul to look upwards and leads us from this world into another.” Obviously, astronomy has always been an interest to mankind. We look up into the night sky and feel an urge, something pulling us towards the stars. Many people have been influential in discoveries involving the stars and the planets beyond. From Galileo Galilei to Stephen Hawking, we have learned and discovered amazing things about the universe, and in recent discoveries we have wondered if…

Introduction Molecular orbital theory allows for the relation between the nature of chemical bonds and the properties of molecules.1 Many times, the frontier molecular orbitals, named HOMO and LUMO, are analyzed in order to predict these properties. In this lab, each double bond corresponds to a molecular orbital. The HOMO, or highest occupied molecular orbital is the most energetic (highest n-value) orbital that contains an electron. The n-value is equal to the number of double bonds present.…

the world, most of the things happening everyday would stop. Most people know what computers are and how they work, but there is a special kind of computer that not many people in the world are aware of, that is Quantum Computers. So, you may ask “What is a Quantum Computer?”, well a quantum computer is not an ordinary computer because of many reasons, the…

Moving Target Defense The current cybersecurity environment is based around a static defense that has been employed for the past few years to protect information systems (See Figure 6). Unfortunately, this cybersecurity paradigm is not effective against current and future cyber threats. According to Zheng (2014), the weakness of this cybersecurity approach is its passive and reactive nature towards safeguarding information systems. Additionally, this method also allows threat actors the time…

commuting from and to work in cities or metropolitans. Because of the speed of human consumption in this market, the inevitable wear and tear of machine parts necessitates a need for automotive mechanic shops. These automotive mechanic or repair…

A bow is basically a two-armed spring that stores mechanical “potential energy” once the string is drawn and pulls back the limbs. After you recoil the cord, you utilize your muscles to exert a force on the string that bends the limbs backward. The quantity of force that your fingers exert on the string once you’ve to force it all the means back is named the “draw weight.” The elastic or spring energy is currently “potential energy” that may be reborn into launching associate arrow after you…

Intuitively we know that the size of an object can have a significant impact on its dynamics. We have seen athletes or animals creating moves beyond our imagination, as shown in Fig. 4.1. This is because their ability in manipulating different parts of their bodies in creating dynamic complexities shown in the images. Certainly we would not be able to ignore the role played by each part of the body if we were to analyze the dynamics of an extended object. However, there is one point, associated…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…
