Graphene is a two-dimensional carbon allotrope. It is composed of carbon atoms positioned in a hexagonal design, which can be said to resemble a chicken wire. A single layer of carbon atoms arranged in such a honeycomb structure forms a … Continue reading →

Lithium cobalt oxide is the most common lithium battery type as it is found in our electronic devices. What is the main ingredient in lithium batteries? The role of the electrolyte inside of a lithium-ion battery is to help transport … Continue reading →

Nanoparticles can be used for drug delivery purposes, either as the drug itself or as the drug carrier. The product can be administered orally, applied onto the skin, or injected. Is it safe to inject nanoparticles? For example, binding of … Continue reading →

Nuclear pasta. Summary: A team of scientists has calculated the strength of the material deep inside the crust of neutron stars and found it to be the strongest known material in the universe. Which is the most powerful thing in … Continue reading →

Graphene is the thinnest compound known, the best conductor of heat at room temperature, the best conductor of electricity ever known, and is 100-300 times stronger than stainless steel, among other amazing properties. Is graphene a better conductor than silver? … Continue reading →

Sapphires of fine quality are in fact very rare. Diamonds, for example, are in almost every type of jewelry, in every jewelry store, and on websites around the world. The world production and use of diamonds proves that diamonds are … Continue reading →

Most studies agree gold is overall the more rare of the two metals; however, above ground silver is actually more rare than gold. Estimates report gold is 5-7x more abundant above ground than silver. Beneath the surface, silver is approximately … Continue reading →

100 years. How long will a neodymium magnet last? Neodymium magnets are permanent magnets, and lose a fraction of their performance every 100 years if maintained within their optimum working conditions. Do neodymium magnets wear out? Very little. Neodymium magnets … Continue reading →

The average concentration of gold in Earth’s crust is ‘very, very low,’ at 4 parts per billion. In its elemental form, gold is significantly rarer than diamonds. Is diamond worth more than gold? Diamonds are much more expensive than gold. … Continue reading →

Normally a NIJ Level IIIA bullet proof vest in combination with Level IV hard armor panels can stop AK-47 rounds including armor piercing. Level IV hard armor panels can be purchased by officers and are not restricted to military personel. … Continue reading →

A report from February 2012 says an iPhone sufficiently slowed a bullet to stop it reaching the owner’s heart. Although it does seem the bullet had already smashed through a car’s windshield first, which likely helped stop it. Can a … Continue reading →

You may know that diamond, with a hardness of 10, is the hardest material in the gem world. Which stone is most powerful in astrology? Blue SapphireThe strongest and most fast acting gemstone, Blue Sapphire or the Neelam is one … Continue reading →

For about a decade, scientists and engineers have been developing sodium batteries, which replace both lithium and cobalt used in current lithium-ion batteries with cheaper, more environmentally friendly sodium. What can replace lithium? Are there any lithium battery alternatives? Salt. … Continue reading →

Graphene is a two-dimensional material, basically a single layer of graphite, with carbon atoms arranged in a hexagonal, honeycomb lattice. Carbon nanotubes are hollow, cylindrical structures, essentially a sheet of graphene rolled into a cylinder. Is graphene a CNT? CNT … Continue reading →

While the positive aspects of titanium would tend to make it better as a sword than steel, titanium deforms quicker than steel. So a titanium sword would be easier to handle and lighter, it would dull and bend on the … Continue reading →
