Do we already know how to convert carbon dioxide emissions into fuel?

A team of scientists from the University of Toronto suggests having found a way to convert all carbon dioxide emissions, responsible for the greenhouse effect, into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon . Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth's crust.
Why does toothpaste make everything we eat taste bad?
Why does toothpaste make everything we eat taste bad?
If you brush your teeth with a typical toothpaste, even if you then rinse your mouth thoroughly, it will be enough for you to drink a simple orange juice so that it tastes horrible. Why does toothpaste alter our sense of taste with this and other foods to such an extent? The secret lies in a single toothpaste ingredient: sodium lauryl ether sulfate (SLES).

This new type of calcium salt could replace lithium in batteries that store solar and wind energy
A recently synthesized chemical could pave the way for the manufacture of calcium-based batteries, which could be safer and cheaper than current lithium-based models. Lithium-ion batteries in mobile phones and other electronic devices have numerous drawbacks: sometimes they catch fire and depend on increasingly scarce and toxic substances such as lithium and cobalt.

The most stinky substance in the world is called Standard Bathroom Malodor, and was created by the United States Government. It is a transparent liquid composed of all the chemical substances that give the bad smell to the excrement. Its smell is so strong that it can be detected in concentrations as low as a part of Malodor by 999.
This is how mining, in ancient Rome, increased the rate of lead in the atmosphere by at least a factor of 10
This is how mining, in ancient Rome, increased the rate of lead in the atmosphere by at least a factor of 10
In the film "The Life of Brian", after a harsh criticism of the Romans, a question is asked to those present at a meeting of the popular front of Judea: "And in return what the Romans have given us?". The answer is the aqueduct, roads, sewerage, sanitation, education, wine, public toilets ... and mining should be added, which was so transcendent that it even polluted the skies of Europe.
The one that is considered the oldest periodic table in the world is restored
The one that is considered the oldest periodic table in the world is restored
Chemistry is the bricks that constitute all the things that surround us, including ourselves. That is why the Periodic Table of the Elements is so important. And now the oldest of all has been restored, from 1885, and it was discovered at the School of Chemistry at the University of Saint Andrews in 2014 by Dr. Alan Aitken during a cleaning.
It is discovered why whiskey tastes better if some water is added
It is discovered why whiskey tastes better if some water is added
Despite all the efforts that are taken to distill a good whiskey, abundant in nuances in both its flavor and aroma, it finally seems that adding a few drops of water improves the experience when tasting it. This idea was already taken for granted, but a group of Swedish scientists has found out the reason at the chemical level.
How much oxygen does all of humanity breathe?
How much oxygen does all of humanity breathe?
It is the chemical element of atomic number 8, atomic mass 15.99 and symbol O; It is a colorless and odorless gas that is found in the air, in water, in living beings and in most of the organic and inorganic compounds. It is also essential for human beings to live. But how much do we all consume?
Van Gogh's sunflowers are going to wilt, according to an X-ray study
Van Gogh's sunflowers are going to wilt, according to an X-ray study
A new analysis shows that half of the canvas held in Amsterdam is painted with pigments that darken with exposure to ultraviolet light. Vincent Van Gogh could hardly have predicted that, more than a century later, those bright yellow tones would begin to wilt in a brown confusion.
This periodic table allows us to know what we do with each element
This periodic table allows us to know what we do with each element
The periodic table is an important scientific tool but difficult to memorize, in addition to that, for the lay people, it hardly offers information about what we are reading. Keith Enevoldsen, a software engineer with a degree in physics has created a more useful version of the periodic table that makes it easy to see what all the elements can do.
All elements of the periodic table can be converted into a gas
All elements of the periodic table can be converted into a gas
Although we intuitively discover great differences between solid, liquid or gaseous objects, they are fundamentally the same thing: it only differs in the behavior of the molecules that make them up. Everything was gas For that reason, with enough heat, all the elements of the periodic table can theoretically become gas, no matter how solid they are before.
Alan Turing's latest article is inspiring a better way to desalinate water
Alan Turing's latest article is inspiring a better way to desalinate water
The ideas of Alan Turing's latest published document could offer a new solution to the problem of converting salt water into drinking water. Turing, best known for deciphering the German Enigma machine during World War II and for developing the foundations of modern computing, published a chemistry article two years before his death.

The gold that allows us to explore the universe is the same that constitutes the Oscar
Formerly, the statuettes of the Academy of Hollywood, the Oscars, were covered in a tin alloy and then had plated them in gold. They glowed, but the cape faded in a short time, dimming. The statuette shows a naked knight holding a sword on a five-spoke film roll, which represents the original branches of the Academy: actors, writers, directors, producers and technicians.
This is the oldest wine and is 8000 years old
This is the oldest wine and is 8000 years old
The wikipédica authority is limited to describe the wine like a drink obtained through the fermentation of the grape, and that the archaeological testimonies suggest that this broth was produced for the first time in the Neolithic, between 9000 and 4000 a. and. c., in the Zagros Mountains, between the north of present-day Iran and Armenia.
Wearing tattoos could have adverse health effects depending on the ink
Wearing tattoos could have adverse health effects depending on the ink
The impurities that contain the mixtures of color that are injected into the skin, the tattoos, when they seep into the body of the tattoo are still quite unknown. A recent study provides the first evidence that pigments, both organic and inorganic, are filtered inside the body in the form of micro and nanoparticles until they reach the lymph nodes, also dragging substances whose effects are ignored.

How it was discovered that oxygen was what it was
It was not until 1789 that the French chemist Antoine Lavoisier managed to demonstrate that the role of oxygen in combustion, and consequently left in evidence the phlogiston theory of Georg-Erns Stahl, who had dominated scientific thinking for half a century (and that until recently, it also dominated much of the literature).

This 'bionic leaf' forms fertilizer for your plant
A 'bionic' leaf that uses bacteria, sunlight, water and air to fertilize the same soil where crops are grown has been developed by Harvard researchers. The development has presented results at the 253 Meeting of the American Chemical Society (ACS). Bionic leaf This artificial leaf, of which we already knew previous developments, is actually used to make fertilizer. It is a device that, when exposed to sunlight, mimics a natural leaf by dissociating water into hydrogen and oxygen.
