Imagine You Are An Aluminum Atom : Discussions With Mr. Aluminum
Join "Mr. Aluminum," a scientist who has made the study of aluminum his life's work, on a journey of discovery, reflection, and the science of aluminum. Professor Christopher Exley is a firm believer that science is only useful when it is properly communicated.Scientific papers are difficult vehicles for the wider communication of science and thus he has always endeavored to tell the story of his scientific research as widely as possible through myriad blogs, presentations, and interviews.Through a series of easy-reading entries written for non-scientists, Exley will educate readers about his lifelong scientific passion: aluminum.In scientific circles, aluminum—in relation to human health specifically—has gone the way of the dinosaurs (though, unlike dinosaurs, there has not yet been a popular revival!).Yet aluminum is also the greatest untold story of science. But why do we all need to know a little bit more about aluminum?Do we need a self-help guide for living in what Exley has coined "The Aluminum Age"?What is it about aluminum that makes it different? What about iron, copper, or any of the so-called "heavy metals," like mercury, cadmium, or lead?Why must we pay particular attention to aluminum? Because its bio-geochemistry, its natural history, raises two red flags immediately and simultaneously. These two danger signals are easily missed by all of us and easily dismissed by those whose interests are conflicted by aluminum’s omnipresence in human life and consequently, are purposely blind to its danger signals.First, aluminum, in all of its myriad forms, is super abundant; it is the third most abundant element (after oxygen and silicon) of the Earth’s crust.Second, aluminum is super reactive; it is both chemically and biologically reactive.However, these two red flags identify a paradox, as the abundant and biologically reactive aluminum has no biological function either in any organism today nor in any extinct biota from the evolutionary past.This means in practical terms that when we encounter aluminum in our everyday lives, our bodies only see aluminum as an impostor, something foreign, and something for which we have not been prepared through biochemical evolution.This in turn means that all of our encounters with aluminium are adventitious, random, and chaotic. And potentially dangerous. Imagine You Are An Aluminum Atom: Discussions With "Mr. Aluminum" examines the science of aluminum and human health and makes them understandable to all.Within the science you will find personal recollections of events, as well as opinions and reflections upon how the politics of aluminum have influenced and interfered with doing and reporting the science.It is at once both a personal recollection of Exley's life in aluminum research and a guide on the dangers of the constant exposure to aluminum we as humans face during this "Aluminum Age." It will inform, it will provide the means to question the science, and it will, if the reader is prepared to participate, answer those frequently asked questions on aluminum and human health.

Which kitchen appliances have a long lifespan, such as mixers, etc.?
Kitchen appliances that typically have a long lifespan include mixers, food processors, and high-quality blenders. These appliances are built to withstand frequent use and are often made with durable materials that can last for many years. Investing in well-known brands and models known for their longevity can also help ensure that these appliances have a longer lifespan. Regular maintenance and proper care, such as cleaning and storage, can also contribute to extending the lifespan of these kitchen appliances.

Why doesn't an aluminum cooking pot burn?
Aluminum has a high melting point of 660.3°C (1220.5°F), which is much higher than the typical cooking temperatures used on a stovetop. This means that the aluminum pot can withstand the heat without burning or melting. Additionally, aluminum has a strong oxide layer on its surface that forms naturally when exposed to air, which further protects it from burning or reacting with the food being cooked. This oxide layer also prevents the aluminum from leaching into the food, making it a safe and durable material for cooking pots.

Which kitchen appliances also have a long lifespan, such as mixers, etc.?
Kitchen appliances such as mixers, blenders, and food processors are known for their long lifespan. These appliances are designed to withstand heavy use and are built with durable materials, making them reliable for many years. Additionally, high-quality brands and models of these appliances are often built to last, making them a worthwhile investment for any kitchen. Regular maintenance and proper care can also help extend the lifespan of these appliances.

Are kitchen utensils made of aluminum harmful to health?
Kitchen utensils made of aluminum are generally safe to use. However, prolonged exposure to acidic foods or high heat can cause small amounts of aluminum to leach into the food. While the amount of aluminum that leaches into food is typically minimal and considered safe for most people, individuals with certain health conditions, such as kidney disease, may want to limit their exposure to aluminum. To minimize any potential risk, it is recommended to avoid cooking highly acidic foods for long periods in aluminum cookware and to opt for stainless steel or cast iron utensils for those dishes.

Is aluminum the same as aluminum hydroxide?
No, aluminum and aluminum hydroxide are not the same. Aluminum is a chemical element with the symbol Al and atomic number 13, while aluminum hydroxide is a compound containing aluminum, hydrogen, and oxygen. Aluminum hydroxide is commonly used as an antacid to treat heartburn, indigestion, and upset stomach, while aluminum is widely used in various industries for its lightweight and corrosion-resistant properties.

How is aluminum extracted from aluminum oxide?
Aluminum is extracted from aluminum oxide through a process called electrolysis. In this process, aluminum oxide is dissolved in molten cryolite, which lowers its melting point and allows it to conduct electricity. Then, a direct current is passed through the molten aluminum oxide, causing the aluminum ions to migrate to the cathode, where they are reduced to form aluminum metal. The oxygen ions migrate to the anode, where they combine to form oxygen gas. This process is energy-intensive but allows for the extraction of pure aluminum from aluminum oxide.
-
How can one extract aluminum from aluminum oxide?
Aluminum can be extracted from aluminum oxide through a process called electrolysis. In this process, aluminum oxide is dissolved in molten cryolite, which lowers the melting point of the mixture. Then, an electric current is passed through the molten mixture, causing the aluminum oxide to break down into its elements. The aluminum ions are attracted to the negative electrode (cathode) and are reduced to form aluminum metal, while the oxygen ions are attracted to the positive electrode (anode) and are oxidized to form oxygen gas. This process allows for the extraction of pure aluminum from aluminum oxide.

How do you calculate aluminum atoms and aluminum oxide?
To calculate the number of aluminum atoms in a sample of aluminum, you would first determine the mass of the sample in grams. Then, you would convert this mass to moles using the molar mass of aluminum. Finally, you would use Avogadro's number (6.022 x 10^23) to convert moles of aluminum to atoms. To calculate the number of aluminum oxide molecules, you would follow a similar process. First, determine the mass of the sample in grams and convert it to moles using the molar mass of aluminum oxide. Then, use Avogadro's number to convert moles of aluminum oxide to molecules. Remember that aluminum oxide has the chemical formula Al2O3, so you would need to account for the number of aluminum and oxygen atoms in each molecule.
