The Airbus A380 is the world's largest passenger airliner. Manufactured by the European Aeronautic Defence And Space Company (EADS), the double-deck, four-engine plane first flew in 2005 and entered commercial service in 2007. The superjumbo A380 offers 50 percent more cabin area than its nearest competitor, the Boeing 747. In a single-class configuration, the A380 seats up to 853 passengers. As of July 2011, 51 Airbus A380s had been delivered to six airlines. Seventeen airlines currently have A380s on order.
Flight simulators have always fascinated those who wanted to see how it would feel to sit in an airliner cockpit. The initial games were very limited, as many of them only detailed the cabin and left the rest for the imagination of the players. However, there are now 3D Airbus games focusing on the aircraft that give players a detailed simulation of flying an airliner.
Within 24 hours, a human cell can divide into two daughter cells that are identical to the original. This cell cycle includes growth of the cell, duplication of the DNA and division of the chromosomes and cell contents. The stages of the cycle -- which occur in both plants and animals -- are called interphase, mitosis and cytokinesis. Kinetochore and nonkinetochore -- also known as interpolar -- microtubules play an important role in the separation of chromosomes and the formation of daughter cells. These microscopic structures are both made from subunits called tubulin, but they have different functions during cell…
Silver oxide batteries uses silver oxide as the positive electrode and zinc as the negative electrode. In general, sodium hydroxide or potassium hydroxide serves as the alkaline electrolyte. The significance of this alkaline electrolyte is that it enables these batteries to remain functionally efficient under high-drain circumstances.
Battery terminal corrosion can be as a result of several things: overcharging, poor electrical connections, leakage or simply not storing your battery correctly contribute to corrosion. The earlier you see signs of corrosion on your battery terminals, the more likely you are to halt the corrosion, before it gets to an irreparable stage.
Dinitrogen oxide, also known as nitrous oxide or dinitrogen monoxide, is a naturally occurring atmospheric gas. It's used in medicine for its analgesic and anesthetic effects; dinitrogen oxide is also responsible for contributing to the greenhouse effect and destruction of the ozone layer. The Science Daily website says that human activity such as releasing effluent from wastewater treatment plants and agricultural fields artificially increases the amount of dinitrogen oxide in the atmosphere.
Leaking batteries can cause damage to electrical equipment and may also present dangers to you as they contain chemical compounds and sometimes acids. Batteries are generally very safe, if used and stored correctly, and improvements in battery construction has reduced the incidents of battery leakage. It wise to understand the main cause for batteries to leak so you can try and avoid it happening.
As implied by the name, a fast battery charger charges your battery much quicker than a regular charger. However, there are a multitude of chargers available on the market, often using confusion terminology to describe their function.
Batteries can burst and corrode the terminals in electronic items and toys when they haven't been in use for long periods of time. The caustic material inside the batteries can interfere with the ability to operate the toys, but with the right method, you can remove corrosion from the battery terminals and restore the toy's function. Remove the batteries from toys that won't be in use for long periods of time to prevent battery corrosion.
Regular alkaline batteries are not designed for recharging --- although there are rechargeable alkaline manganese (RAM) batteries on the market, but reports about them are poor and it's understood they can only be recharged about 20 to 30 times. There are a few things that can happen if you decide to put a regular alkaline battery into a charger, so caution needs to be exercised.
Sony batteries, like most batteries, have a "+" and "-" sign on them. These signs mean positive and negative, respectively, and show you which way you need to put your battery in your electronic device. These signs, however, are more than just symbols to tell you how to arrange your battery; rather, they have more to do with the nature of the battery and electricity itself.
The element aluminum forms a number of different chemical compounds. Two of these are aluminum chloride (AlCl3) and aluminum fluoride (AlF3). These two chemicals are similar in several ways; they both, of course, contain aluminum and they have similar molecular structures. As well, both chlorine (Cl) and fluorine (F) are in the category of elements known as halogens. However, there are also many important differences between these two compounds.
Silver oxide batteries are typically small and rather specialized. They were invented during World War II to meet the military's need for compact power supplies with longer life than the zinc-carbon batteries then available. The silver oxide battery has a long shelf life and can withstand a high discharge rate while still delivering a steady voltage. While not recyclable, it is an environmentally safe battery to dispose of once it is exhausted.
The Airbus A330 series, consisting of the Airbus A330-200, A330-300 and the A330-200F Freighter, are Airbus' largest twin-engine commercial airliners. These are wide-body planes with capacity ranging from 256 to 335 seats, designed for use on medium-range routes. Development of the series began in 1987 and first flight of the A330-300 occurred on November 2, 1992. The A330 was developed in concert with the four-engine Airbus A340 and shares many systems with the bigger plane such as airframe, flight deck and wings. Airliners of the A330 series also share many specifications among themselves, but there are several significant differences.
Mixing batteries is not something battery manufacturers recommend as each manufacturer, understandably, would prefer you to use only its own batteries. However, as long as the batteries are the same type and chemically the same (for example, don't mix alkaline with nickel batteries), you won't damage your electrical device by mixing them.
Alkaline Batteries are one of several types of "dry cell" designs which use a solid electrode surrounded by a chemical paste to generate electricity. These typically come in 1.5-volt, 6-volt, and 9-volt designs. Alkaline cells were introduced into the marketplace in the 1960s. Alkaline batteries are clearly superior to the older zinc-carbon type, but are not on par with some newer battery designs.
Batteries power much of our world. Although the term "battery" is generic, each type of battery is actually very different from other types. Some come in extremely small packages, while others are large and heavy. The capacity and composition of individual batteries varies as well. Whether powering your remote, or your vehicle, learning the ins and outs of batteries might prove useful someday.
Batteries used to power portable devices are lithium-, nickel- or alkaline-based. Lithium and nickel batteries are rechargeable, but alkaline batteries are not. It's important to know the chemical composition of your battery, because attempting to charge an alkaline battery can damage your charger and may be dangerous. Fortunately, an alkaline battery can be easily identified by reading the battery label.
A battery harnesses a type of chemical reaction called a redox reaction, where electrons are lost by one species and gained by another, to generate electricity. Although all batteries rely on the same principle, they vary widely in terms of their materials and chemistry. These differences ensure that some batteries are better suited for certain applications than for others.
Alkaline batteries are one of the most common types of batteries used by consumers to power personal electronic devices like toys, cameras, clocks and handheld appliances. They generally provide power for a long time and perform well in a variety of temperatures. Alkaline batteries can be stored at room temperature for two years and still perform at 90 percent of their original capacity. However, they can be bad for the earth because of the potassium hydroxide and mercury that may leak out of them and into the soil long after they are discarded. Powering devices with other forms of energy…
Duracell manufactures a wide range of rechargeable and non-rechargeable batteries. Some Duracell batteries have a power meter on the side, making it easy to tell how much charge your battery has. Put your thumb and forefinger on the marks on each end of the battery and the meter displays the amount of charge. However, if your Duracell battery doesn't have a power meter, you can tell when it's fully charged by using a multimeter.
Batteries provide electrical power to a device without having to use a wall outlet. With many portable devices, you can choose to install non-rechargeable alkaline batteries, or you may opt to install rechargeable batteries -- either nickel-cadmium or nickel-metal-hydride -- instead. It is important to understand the differences between each type of battery before making that choice.
Batteries used in portable electrical devices use one of three distinct chemical bases: alkaline, nickel and lithium. Alkaline batteries are usually nonrechargeable, while nickel and lithium batteries are rechargeable. All batteries are clearly labeled, showing their chemical composition, voltage and milliamps hours so you can easily see if your battery is alkaline.
Alkaline batteries are similar to, and replacing, older zinc-carbon batteries. This is because alkaline batteries last longer and are more powerful. Alkaline batteries can be used in all types of products, such as flashlights, clocks and cameras. The alkaline battery comes in variable sizes from AAA to 9 Volt. The many advantages of alkaline batteries including cost-effectiveness, more energy, being able to be purchase them in rechargeable varieties and increased safety.
Though you may forget about them until you need to change them, batteries power many of the things you use every day, from your television remote and your children's toys to your computer and your cell phone. Several factors affect the life of a battery, including the ambient climate and the materials used to make it. You can test these factors to ascertain how to keep your batteries running as long as possible.
When you're right in the middle of making your best shot in Tiger Wood's PGA Tour Nintendo Wii game and your hand-held controller battery dies, no doubt your teeth could grind glass. Avoid this next time by finding the longest-lasting alkaline batteries to power your Wii's controller, which requires two "AA" batteries. Alkaline batteries are one of the options available to you when it comes to powering the Wii controller that puts you in the middle of the action. All batteries reviewed have a cut-off voltage of 0.8 watts and tested at a rate of 10 ohms.
Discarding batteries along with the rest of your trash poses several environmental concerns. Depending on the type, batteries can contain several dangerous heavy metals including mercury and lead which will eventually leak into the soil and groundwater. Incinerating batteries only releases some toxins into the air and concentrates the others in ash. Though the need for a better disposal system is clear, the federal government has set few standards. Though not always required by law, there is an ideal disposal method for each battery type.
Batteries are not a new invention. The website All About Batteries reports that in 1936, a battery was found dating back to the Parthian Empire. Testing replicas of this ancient battery revealed that it was capable of generating up to two volts. By the 1800s, battery development began to be more successful, but it wasn't until 1949 that the alkaline battery, so ubiquitous today, was developed. When using an alkaline battery, there is a risk that when it's overcharged, it may leak. Fortunately, this is something that you can clean safely.
The chemical reactions in a battery produce electrical voltage and current. Its nominal voltage is based on the metals and chemicals it uses. The maximum voltage the battery produces depends on factors including charge and temperature.
Wii wireless remotes use rechargeable batteries to operate. These batteries are charged on an induction charger and Energizer makes battery packs that are compatible with these chargers. When necessary, simply add the battery pack to the Nintendo Wii remote.
The Environmental Protection Agency (EPA) estimates that Americans purchase almost 3 billion dry-cell batteries per year. The most familiar types of these batteries are the household 1.5 volt batteries, which come in sizes AAA, AA, C and D.
Batteries turn chemical energy into electricity. Many you can buy use alkaline chemicals, though some use lithium. You can substitute a lithium battery for an alkaline one, but its size and voltage must match.
There are five common household batteries, plus a sixth type used in some types of camping gear. In voltage, the four round battery types carry a similar charge with widely differing current capacities. The two "square" battery types are made for specific voltage and current capacities, and are generally single-use cells without the recharging capabilities available in the round types.
The familiar D battery is a cylindrical low-voltage battery. It delivers 1.2 to 1.5 volts, depending upon the chemical composition of the battery. The rechargeable version has a slightly lower voltage than the alkaline version. Many portable appliances, such as flashlights and children's toys, combine two or more D batteries to create a higher voltage. To do the same thing, you need only basic electrical knowledge and access to simple tools.
From its beginnings as the Mallory Battery Company to 1964 when the Duracell name was introduced and on to the present, the company has focused on producing batteries to meet the needs of consumers. Batteries must be manufactured according to strict specifications, some of which are determined by outside entities and others by Duracell itself.
Batteries function by converting stored chemical energy into electrical energy. There are two types of batteries: primary and secondary. Primary batteries are used once and then thrown away. Secondary batteries can be used and then recharged several times. Batteries also range in size. The smallest are used in items such as hearing aids and the largest units are used for standby power for telephone exchanges or large computer data organizations.
Alkaline chemicals and bases are the same thing. They are the opposites of acids, and have a pH greater than 7. Water is a neutral compound with a pH around 7. Alkaline chemicals taste bitter and feel slippery, but be careful: strong bases cause damage such as burns, and OSHA labels them as corrosives. OSHA defines corrosives (in 29 CFR 1910.1200 App A) as a "chemical that causes visible destruction of, or irreversible alterations in, living tissue by chemical action at the site of contact." However, weak bases constitute a main ingredient in soaps.
Before you reach into the drawer and pull out an old pair of alkaline batteries for your remote control, you should test them first. This simple test will help prevent damage to your electronic equipment and save you the grief of discovering the batteries have no charge. However, in order to properly test alkaline batteries, you need to follow specific instructions.
Alkaline batteries store electrical power for later use in small electrical devices. They commonly come in one-and-a-half volt sizes. They can sit in storage for long periods of time before use. Therefore it is a good idea to check their voltage level before putting them into use. You do not have to buy a special battery tester to test your alkaline batteries; a simple multimeter will do the trick.
Alkaline batteries are used frequently in modern life in everything from remote controls to toys. Alkaline batteries contain various chemicals, including zinc, manganese dioxide, potassium hydroxide and graphite. If an alkaline battery is not used for long periods of time, chemicals may leak out of the ends of the battery, causing a white powder to form. This white powder is potassium hydroxide, which you can easily clean with a vinegar and water solution.
Duracell, one of the best-known manufacturers of batteries, offers many types of consumer-grade batteries, which it classifies by size and power (e.g., AA, AAA, C, and D). These batteries are ideal for household devices like remote controls, flashlights, clocks and toys. In addition, Duracell manufactures Procell AA batteries, which are appropriate for a variety of more demanding professional applications, from wireless microphones to blood pressure monitors.
The Nintendo SP took the gaming world by storm by offering a hinge across the back edge of the unit, which allows the user to close the upper portion and protect the screen from harm. However, the Nintendo SP features a notoriously poor rechargeable battery that will abruptly loose juice without warning, and occasionally smokes or leaks battery acid. Replace faulty rechargeable batteries with easily replaceable AA alkaline batteries, a modification that also brightens the game screen.
All batteries work by converting chemical energy into electrical energy. The purpose of a battery is to store energy until it is needed to power a device. Only when the device is turned on, creating a closed electric circuit, do the chemicals react and produce energy in the form of electric current. Disassembling a battery can help you understand how it works. However, be careful not to expose your battery to heat, and do not short-circuit it by connecting both terminals to metal; a buildup of internal heat and pressure could explode your battery.
A simple-yet-elegant device, the modern alkaline battery has only a few main components. The difference in electron affinity between zinc (Zn) and manganese dioxide (MnO2) drives its basic reaction. Because the manganese dioxide has a greater attracting power for electrons, it creates a potential for electrical current.
Potassium hydroxide is a strong base that can leak from alkaline batteries. You can clean up after a leaky alkaline battery by using acid to counter the alkalinity. You'll also want to clean the electrical contacts of any equipment the battery was in. Alkaline battery leaks tend to happen in flashlights after the batteries have run down, but they can also happen in expensive lab equipment left shelved for an extended period--which can be a more delicate and more consequential cleanup.
The term alkaline is commonly used as a synonym for for soluble bases. Although the terms, alkali and base (basic), are used interchangeably, their meanings are not the same. All alkaline solutions are basic, yet not all bases are alkaline. A common mistake is referring to the alkalinity of a substance, such as soil, when pH (a base) is the property of measurement.
Leaving a battery attached to a terminal for long periods of time can result in corrosion around the terminals. Batteries contain an alkaline, potassium hydroxide, that can leak onto the terminals and cause a rust-like material to develop on the metal, which can prevent the item from working properly. Cleaning the terminals is relatively simple and can return the item to working order.
First designed by Lew Urry of the Eveready Battery division of Union Carbide in 1959, the alkaline manganese dioxide--or alkaline--battery of today can supply power some 40 times longer than the originals, thanks to refinements to meet the needs of modern personal electronics. The familiar positive and negative posts are merely bookends for the components that make alkaline batteries both powerful and safe.
The feel-good commercials for Duracell and the often-humorous ones with the Energizer bunny on U.S. TV reveal the dominance of the alkaline battery in battery-powered devices today, ranging from smoke detectors to remote-control vehicles.
Batteries are composed of positive and negative terminals and electrolytes. An electrolyte is a solution that conducts electricity. Household batteries such as AA, C and D share the same voltage but have different current capacities. Batteries have different voltages based on their electrochemical compositions.
The most common battery type is AA. AA batteries are typically dry cells, which are made with an electrolyte that is inside a paste. An electrolyte is a solution that conducts electricity. When under a load, a thin rod inside of the battery reacts with the paste to produce a voltage.
The choice to use a silver oxide or an alkaline battery won't be available in many cases. The cost of large silver oxide batteries, if they could be found, would be so expensive that they would not be practical, especially when there are so many types of rechargeable batteries available. So the comparison should only be made for smaller and nonrechargeable applications.
The alkalinity of a liquid is indicated by its pH level. The scale generally ranges from 0, a very strong acid, to 14, a very strong base. A neutral solution such as pure water has a pH of 7. Testers are used in a variety of applications such as electroplating, gardening and winemaking. A pH tester normally becomes inaccurate over time and will need to be calibrated.
While the alkaline battery's cathode is on the battery's outside, it is actually produced first. The material used to make the cathode is primarily a mixture of manganese dioxide and an electrolyte called potassium hydroxide--as opposed to ammonium chloride or zinc chloride in other batteries--along with graphite. These materials ground up into granules, mixed together, aged and compacted into a circular hollow tablet. A single battery usually uses three of these tablets, which are inserted into a steel can. The can and tablets combine to make the cathode. Sealant is placed near the top of the can to prevent the…
There are many different types of batteries on the market. Depending on the type of battery and the materials used in manufacturing, different batteries need to be handled differently. Some batteries contain materials that are hazardous; these materials can seep into the groundwater. Before you throw a battery in the garbage, determine which type it is and make sure that you are not threatening the environment with chemicals that can be dangerous.
Alkaline and lithium batteries are the two most common types of batteries used as personal power sources. Both have different chemical compositions and voltage ranges; these differences become more significant as lithium batteries cross over into the AA and AAA market that alkaline batteries once dominated.
The alkaline battery can take the square or cylindrical form that we all know so well. The contents are contained safely within a steel casing. The cathode, which is the negative part of the battery, is a compressed mixture of manganese dioxide paste and carbon powder. The center of the cathode is hollow and lines with a conductive separator to prevent the cathode and anode materials from mixing, but allowing their varying electrical potentials to pass from one to the other. The anode is the positive part of the battery and contained within the center of the cathode. It's a…
