Advantage And Disadvantage Of Smartphones

As a powerful and flexible membrane, graphene offers basic INFI infinite possibilities of the carbon chain modifi cation or function. Graphite oxide (GO) provides a potential CMG ton scale production. First, nearly 150 years ago, has become the potential [GO precursor provides a graphene based material mass production and cost-effective.

It is currently used to manufacturer sporting goods and electronic components. Scientists tout graphene as the next silicon. The material is one million times thinner than paper and harder than diamonds, while conducting 200 times more electricity than silicon – a tremendous implication for the electronics industry. These advances come at a hefty price, but researchers at Caltech have discovered an improved manufacturing process for the material. Once researchers refine this process, manufacturers may also use the material for goods such as solar power and surface

Graphene is a form of carbon which has recently been receiving a great deal of attention. Some have come to call it “the wonder material” due to its many extraordinary properties. Although isolated in 2004, graphene's properties had been calculated decades earlier. It consists of a single layer of carbon atoms arranged in a hexagonal lattice. A single sheet of graphene is stronger than steel and yet remains very flexible, retaining all of its properties despite being bent and unbent multiple times. It is able to sustain extremely high electric current densities, is impermeable to all gasses, has a thermal conductivity double that of diamond and a very high electron mobility at room temperature. It is also easily chemically functionalized,

Throughout modern times we have witnessed many advancements in technology. These advancements are results of research and data collected about our world and society, helping us to better understand the most efficient ways we can work. With this increased knowledge, we have become more aware of the footprint humans leave on the environment. In an effort to better our environment, with this knowledge we have become a more environmentally conscious world. One major advancement we have seen in environmentally friendly technology includes the electric vehicle. Electric and hybrid electric vehicles have brought about many advantages and impacts including: decreased emissions, minimal gas usage, and increased safety.

The possibilities offered by this new type of battery would indeed be considerable. From the smartphone to the tablet, via laptop, GPS or car, all energy consuming mobile power products and requiring regular refills could benefit from the advantages of this new combination. Moreover, these batteries could also be used at much larger scale than the charging alone phones or computers and storing electricity produced by renewable sources such as wind turbines or solar and tidal power.

To achieve higher energy density and a longer lifetime for batteries, my future research focus on the next generation of batteries-solid-state batteries, such as, Metal-Air and Metal-Sulphur batteries. Comparing with lithium-ion batteries, the solid-state batteries have solid electrolyte instead of liquid electrolyte which provides high

When people hear the words “electric vehicles” they often focus on the drawbacks instead of the benefits to owning an electric vehicle. It is stated in the article “A Brighter Future for Electric Cars and the Planet,” that car companies like Tesla and Volvo are developing electric vehicles that will be more affordable and

In today’s technological world people are often tethered to the walls by their jumbles of charging cords, but those days may soon be coming to an end. Advances in recent technology have made it possible to construct a longer lasting power source. In the article “Better Batteries charge forward”, Susan Gaidos explains how building a better battery could have the power to “jolt people to the future”.

In today’s era smartphone plays vital role and affect our lives enormously. Mobile phones were invented to answer long distance calls and at the same time its portability doesn’t bound the user to one place. The basic functions of any smartphone and a mobile phone is to answer calls and it can be used to send text messages. However, what makes smartphones different from a regular mobile phone is its capability of providing interface between extra functions or apps for its users. For example; todays smartphones can help user find directions that is by using GPS, it also helps users to operate their bank accounts without having them to go to bank and many more.

From Tesla’s gigafactory for batteries to new battery technologies every day, this field is ever expanding with inventions and opportunities. Batteries seem like one of the most important paths to the future and I would love to be on the cutting edge of energy

The studies have shown that electric vehicles can reduce greenhouse gas emissions to “6.12 billion tons annually” (Westbrook, 2001). Even though they need mainly coal as a supply of electricity, they produce less harmful emissions than oil, which is the main source of energy for transport modes, driven by gasoline (Westbrook, 2001). With the development of renewable energy technologies that use the power of wind or solar energy, people can get a clean source of electricity, which will make the electric car more friendly to nature. In addition, the introduction of “regenerative braking system” will allow cars to convert the force of inertia into electricity, thus, adding, extra batteries, which, in return, increase its

Fully electric cars are the future of ground transportation. The use of electricity in cars will also have a massive impact on future transportation.

More efficient and durable batteries are needed to satisfy the requirements of new technology developments.

Electric cars are becoming very popular in today’s world and are becoming more main stream. One reason for this is the need for automobiles that have a lower or a zero carbon footprint. For the majority of the history of the automobile, the propulsion system was a gas or a diesel engine that would run off of fossil fuels. The burning of fossil fuels is very hazardous to our world and also creates much toxic pollution. However, electric cars run off of electricity, which is a very clean and pollution free resource, depending on how the electricity was produced of course. In this paper we are going to examine the history of electric cars, look into modern electric car technology, and peer into the future of electric car technology to see if EVs might be the answer to dramatically reducing our global pollution.

Lithium-ion batteries are becoming more common in portable electronic devices due to their high-energy density, lack of memory effect, and high charge and discharge rate capabilities. Research and development work is ongoing to improve safety and increase capacity, charge/discharge rate, and lifetime. Demand for electric vehicle batteries is currently small, but it is expected to grow very quickly. China, Japan, South Korea, France, and the United States are the major lithium-ion battery manufacturers for hybrid and electric vehicle applications.
