Ebola has been in the news a lot and has managed to make a deadly stand in Africa. This deadly virus manages to overwhelm the body's defense system quickly and effectively. Ebola has put the world in a type of hysteria but did you know that this isn't the first time that we have encountered this disease?
The secrets of the sun are hidden in how energy travels up through its layers and out into space. With the help of the NASA's Interface Region Imaging Spectrograph (IRIS) it is now possible to focus various things that have been puzzling scientists and researchers for the longest time at a level of detail that has never been done before.
Bionanotechnology is an emerging science where scientists and researchers learn from how biology works on various levels and apply it in the field of engineering. Mankind has started domesticating plants and animals since the past 10,000 years and now with the help of nanotechnology it is possible to domesticate molecules too.
Reduction is the process when a substance gains electrons whereas oxidation is the process by which a
substance loses electrons. The breaking down of sugar in cells, photosynthesis and fire are all examples
of redox reactions. While trying to understand redox reactions it is critical that you keep track of the
electrons and we will take a closer look at why this is important.
Science just like real life tries to achieve balance in all aspects. In science the word for balance is
equilibrium. When the balance of a natural system is out of balance we say that it is out of equilibrium.
Eco-innovation has evolved into shaping of ideas to create business value while simultaneously taking
care of the environment. Across many countries in Europe in 2011, 3.2 million tones of used tires had to
be disposed off. Recycling techniques have been developed to recover all the materials present in these
tyres which include fiber and metal apart from just the rubber.
The world is currently witnessing a double whammy with depleting fuel sources and the carbon that is released in the atmosphere because of it. Wouldn't it be great if you could put all this carbon released in the air back into your car and burn it for fuel? This puts the concept of recycling in the domain of sustainable fuel and not just materials like plastic or glass. The solution to eradicating our carbon footprint could be not in capturing carbon but in recycling it.
In Greek, stoikhein means element and metron means measure, so Stoichiometry literally translated means the measure of elements or atoms to be precise. Stoichiometry is the aspect of chemistry that deals with a fair bit of mathematics but it is one of the most important tools used by chemists to translate from the very small to the massive.
Do we run on batteries? Just think about all the important things in modern life like laptops, phones, cars and pacemakers, all of them run on batteries and if taken out could put the whole world in a kind of standstill. Further over looked is the fact that like most things in life, batteries have a function based largely in chemistry. The type of chemistry that goes on inside a battery is known as electrochemistry which mainly involves exchange and transfer of electrons. This transfer takes place from an atom donating an electron to an atom accepting an electron. The key in this situation is placing a device between these two halves of this reaction.
The first thing that we learn about an acid is that it is sour; remember the first time you bit into a lemon? The word acid itself comes from a Latin word which means sour and they are good at exsolving substances. The most common acid on earth is water. To add to your confusion water is also the most common base.
