Why Tempered Glass is Used for Cooking Lids

“What type of glass is used for cooking lids?”
Cooking food is one of the most intricate parts of human life, whether it be meal-prepping for the week or dining with friends. And if one is using a pot then one of the most useful things is to see what is going on underneath. That way, we can monitor what processes are occurring and what to do if something goes wrong. Usually, translucent covers are made of glass. However, since cooking involves high changes in temperature and pressure, the glass needs to be extremely strong and sturdy. As a result, tempered glass with its thermal strength is used. This is why Tempered Glass is Used for Cooking Lids.

“What is the highest level of nuclear waste?”

During nuclear power generation, the energy in the fuel rods will become used up. Although it will no longer be effective in creating electricity, it will still be extremely radioactive. The most dangerous form of this is known as High-level Nuclear Waste. High-level nuclear waste must be carefully isolated in strong containers such as water entrapment systems to prevent any form of leakage.

“Why are quantum dots for solar panels so useful?”

 

Quantum dots are bringing a revolution into the world of semiconductors. And since semiconductors are the backbones of solar panels, things will be greatly changed for them as well. The extra emissivity offered by quantum dots means that two and possibly three electrons can be generated for every photon received, vastly increasing its potential! Quantum dot solar panels can achieve as much as 65% efficiency, nearly double of the theoretical limit of normal panels. This is why Quantum Dots for Solar Panels are so exciting.

“What is the next big revolution in semiconductors?”

 

Semiconductors technology is going through a revolution. Nanosize semiconductor materials known as Quantum Dots which can give off light when illuminated are starting to be developed. Their small size allows them to be much more efficient than typical semiconductors and can give off a broader range of lights.

“What is the byproduct of nuclear energy?”

 

Nuclear energy is one of the promising power sources for the decarbonized future. However, like everything in this world it comes with serious consequences. The spent Uranium fuel rods will still give off enough radiation to kill a person for a quarter of a million years, meaning that this High-level Radioactive Waste must be contained somewhere.

“What is Clay?”

 

Many children around the world play with clay when they are young. But what exactly are they? Well, when natural rock or soil material is highly grounded, it can combine with a large amount of other elements overtime to make Clay. Clay’s flexibility and strength when hardened have made it useful in building materials and early writing utensils.
