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…

proves to be living beyond the technology of today. The device is in the interstellar space and is out to make history. Travelling at a speed of 38, 000 miles per hour, the device is set to be the first man-made feature to ever exit the currently known solar system and explore the far galaxies (Cowen, 2013). This success can be attributed to the robust design of the probe, the powerful boost the device was given by its rocket and the propulsion it gained as it traversed Jupiter and Saturn.…

convieneces to solar power, but of course nothing is perfect. It is more convienet for the consumer because they will not have to purchase things to run their house or car, they could just have the solar pannels themselves and be independent. The one and major inconveience of solar power is what do you do on a cloudy day? Or if one place does not get a lot of sun how can it run? Advantages: Solar energy is a renewable resource that is environmentally friendly. Unlike fossil fuels, solar…

Solar Energy Energy is considered as the most important issue of the 21st century. About 85% of today’s modern world use of energy comes from fossil fuels (Blah Blah). These particular resources, fossil fuels, are finite in quantity, and has been a major cause of air pollution and global warming. Scientists are finding alternative sources of energy to solve the century’s puzzle, a resource which is renewable, natural and efficient such as solar energy. Over 2700 years ago, people have been…

When I was a child, I 've always dreamt about going to outer space and explore the universe. Out of curiosity, I became obsessed with space because there were many creative science fiction movies where it shows how space should be like, but I have found myself asking the same question over and over again. Is it really possible to live on another planet? Few years later, I’ve did research through many space expeditions where NASA sent humans onto the moon. When the mission succeeded it was one…

Renewable Energy * Wind * Solar * Geothermal * Biomass * Hydroelectric Wind Energy Wind Energy is an effect of the sun 's uneven heating of the atmosphere. Wind energy is commonly harnessed by turbines. Wind is formed when warm air expands and rises up, while cold air condenses and sinks. Wind energy can be used to power boats or even charge a battery. Although, it 's almost a perfect choice, it has its setbacks. The generators need a lot of land in order to function properly and if…

The Earth’s climate has changed over the centuries, and is expected to continue to rise due to human activites. The burning of fossil fuels releases greenhouse gases that trap heat in the atmosphere, which creates a greenhouse effect and warms the climate. Since human population is increasing, more food is needed to sustain the large population. In return, agriculture adds to this effect because farms release methane. Trees and other plants are needed because they yet they take carbon dioxide in…

to greenhouse gasses, not all of the terrestrial radiation makes it directly back to space. Greenhouse gasses are unique in that they are transparent to solar radiation, but absorb terrestrial radiation. This in return heats up the troposphere, thus the term “Global Warming” is…

The lack of solar power stems from solar panels containing qualities that make them incompatible with the energy grid. The first quality solar panels posses that make them incompatible with the energy grid is the type of electricity produced by solar panels does not match up with the type of electricity the grid runs on. The second property that solar panels possess that makes them unsuitable for the energy grid is the variability of the energy generation from solar panels. A research team…

In this class, Core 1, we have touched on many different subjects. First, we discussed about the origins of the universe in module number one. Afterwards, we touched upon the origins of life in module number two. Currently, we talked over the origins of societies and culture in module number three. Even though the three different modules all seem to be broad and different, I believe they have an important similarity, and that is classification. As humans, we have the tendency to classify…
