Molecular Transistors will make breakthrough in electronics

Nobody can doubt scientists’ effort when it comes to transistors and their importance in modern technological advancements. Over time, transistors have been in the market, designed from singular molecules. Electron flow in these transistors has been facilitated by the modulation of energy produced by molecular orbits or orbital. This behavior has greatly influenced the genesis of current and future molecular transistors and other devices. Since transistors (integration of circuit elements) work with the electric current flowing within the electrodes (drain and source electrodes), trying to improve voltage put to the 3rd electrode, normally referred to as gate electrode, the manufacture of these transistors takes time, money and energy. Determination by scientists and researchers so far have a fruit; they have made a breakthrough with the first molecular transistors being made. This transistor brand is made from one molecule, has its benzene molecule bonded to the vibrant gold contacts, and works or performs like the silicon transistors. The presence of varying energy degrees in the molecule can easily be manipulated by varying states of energy. Through this, you can be able to assert yourself in controlling the passage of current via it.

Nuclear Reactor Types – Are they really safe?

The nuclear power industry and reactor technology have constantly been developing for more than five decades now. Nuclear reactors can be classified based on their nuclear reaction, the moderator material used, generation of the reactor, fuel phase, fuel type, coolant used, etc. The fusion nuclear reactors are mainly dealt with because the fusion reactors are still in the developing stages, and the fission reactors are already being used for the past six decades. Based on nuclear reaction This type refers to the thermal (slow) reactors and the fast reactors based on neutrons’ speed. Thermal reactors are the most affordable and ordinary as they use natural and raw uranium. The neutrons are decelerated from their natural rate when emitted from the broken atomic nuclei and moderated material in the process. Fast reactors are costly that require more enriched fuel.

Full Body Scanners – How do they work?

The new full-body security scanners might become a popular alternative to body searches with the increased alleged terror threats worldwide. The full-body scanning system has taken the world by surprise in the past recent months. The most advanced method of whole-body imaging technology involves scanning the whole body through clothing, revealing both metallic and non-metallic hidden objects, including weapons or plastic explosives. The U.S. Transportation Security Agency (TSA) had already tried this concept of whole-body imaging at six airports in mid-2009 to look for threats that typical metal detectors could not find. The process to install these scanners at more airports in several U.S. cities is already heading rapidly, with the recent alleged unsuccessful terrorist attempt on a Christmas Day flight to Detroit. To combat this threatening problem and for the people’s security, the TSA has worked with two essential technologies to upgrade its passenger screening systems- the Millimeter-wave and the Backscatter X-ray.

Evolution of Solar Cells

With the non-renewable sources of nature diminishing and the global warming effect increasing, Solar energy is vital in the present times because the power demand in the world is a never-ending process. And the emergence of solar cells in the 19th century has signified the importance of solar energy today, in our lives. A solar cell is a device converting sunlight energy directly into electricity using the photovoltaic effect. The term “photovoltaic” is used since 1849, derived from Greek ‘phos’ meaning “light” and ‘voltaic’ meaning “electric” from the name of the Italian physicist Volta. Today, these solar cells or the photovoltaic cells are used to make solar panels, solar modules, or photovoltaic arrays.

Technologies used in “Avatar” Movie

Writer-director James Cameron is making another cinema history with the breathtaking new 3D technology in his latest sensation, “Avatar,” which has swept the world with more surprises giving a new dimension to the world of cinema. Cameron developed this new technology that could finally revolutionize film making by getting the 3D and the CGI to new heights while mixing the real footage and the motion-captured CGI in an immersive 3D technology. A brief review of the technologies used by the director that powered some of the most stunning effects of the movie is given below:

Machine vision faster than human eye

Machine vision is more compact when compared with the other equipment. These equipment types are extensively utilized to develop more organized manufacturing operations carried out at the shop floor without any confusion. The machine vision system is a combination of imaging and controlling hardware that can influence the more complicated equipment utilized in manufacturing like robot-arms. The robot arms are to be calibrated concerning the positional deviation allowed in a particular workstation. Hence precise monitoring of the working of such equipment is necessary. The inspection process greatly relies on utilizing the machine vision system to mobilize better results in the overall production process. Inspection is considered to the shop floor’s life and can greatly decide the operation’s outcome in many ways. Inspecting relatively tiny and but the machine vision systems carry out active components like IC chips. They are supplied with imaging equipment like the camera to focus the change in the position of the component that is to be measured. This setup is employed to monitor the assembly lines carrying the supply of the raw material or finished goods traveling at a constant speed towards the successive workstations.

How does 3D scanning work?

Scanning is considered to be one of the most challenging jobs to be performed by equipment. It creates natural coordinates compared to the general coordinates as specified by the component’s general topography. These use specifically implicate the concept of triangulation. This concept depicts the usefulness of defining the object based on the input signals obtained by the three sensors placed at a specific angle and positional difference. The designers and professionals work 24×7, and their business is to deliver relevant data to the consumer environment. The marketing tool for the 3D scanner is a website where the professional enhance the power and image of consumer and make it easy. Graphics, contents, and colors are incorporated into a functional website for easy direction-finding. The information collected will not be revealed, disclosed, and shared with other hardware systems available with the 3D scanner. All identifiable personal data are ordered depending on the utilization of the service of the scanner. It might sound astonishing, but it is confirmed that many big software companies don’t rely on investment in new technology. For attaining adequate profit, they depend on third-person share and software.

What artificial intelligence can do these days?

Artificial Intelligence is part of a computer science program that deals in making machines behave and perform operations that a human being can commit. People have been trying to make devices behave like humans for a very long time, and today, with the help of advanced computing, people can achieve it. Artificial Intelligence, in short, is termed AI. There are various departments where Artificial Intelligence can be extensively used. Out of all departments, the defense is one area where the artificial department has been widely used. Gaming is another department where artificial intelligence is getting used. Gaming is prevalent among youngsters, and when these machines start responding to human beings’ requests, people get more excited. There is both advantage and disadvantage in Artificial Intelligence. One of the significant benefits is that by using artificial intelligence technology, we can make machines perform human activities, thus minimizing human labor. You can use devices to perform work that human beings found difficult. Nowadays, human beings can sit in their office and control their house computer. Not one researcher can invent an artificial intelligence system, and it takes years to build a proper and advanced artificial intelligence system.

What Is An Atomic Clock?

The atomic clock is a kind of clock that utilizes atomic resonance frequency as its timekeeping feature. These clocks show the exact time and frequency standards and are identified as the primary standards for international time and manage and organize the frequency of the television broadcasts and GPS satellite services. The atomic clock uses the resonance frequency of atoms as its resonator. A resonator is operated by the frequency of the microwave electromagnetic radiation absorbed or emitted by the molecule or atom’s energy change. Thus an atomic clock generates standard frequencies. These are installed at various sites to show time signals. Alpha navigation transmitters and LORAN C. Atomic clocks are very useful in long wave and short wave broadcasting stations to deliver an exact frequency that can act as the standard frequency. Also, atomic clocks have been used in a long-baseline interferometer in radio-astronomy.

Technologies That Fight Global Warming

Global warming is a significant threat to people and the earth. It is an increase in the earth’s surface air and the oceans. Earth now finds it difficult to breathe because of the concentration of greenhouse gases. Greenhouse gases are essential to the earth’s environment. It effectively traps heat in the lower atmosphere and radiates the heat the planet needs. Without greenhouse gases, our earth’s temperature would be 0o F or -18oC instead of 57°F or 14°C. Are we aiding in the enhancement of the greenhouse gases or going against it and making it worse? Man has caused the most damage to greenhouse gases. Through the combustion of oil, coal, and gas, human activities have increased the concentration of greenhouse gases in the atmosphere. Pollution is the biggest human-made problem. Another main problem the cause of global warming is population. To fight global warming, scientists have found different ways to solve the problem. The use of technology in fighting global warming is one of the means to reduce global warming.
