“Is oil used to insulate transformers?”
Transformers are an inseparable part of Critical Grid Infrastructure. And part of their day-to-day functioning requires insulation material. However, such material will have to be able to withstand high temperatures and sudden electric discharges. This is commonly solved using Transformer Oil, a substance employed all around the world.
“Can a thermodynamic process be so slow that it’s almost static?”
Thermodynamic processes can happen over any period of time. Sometimes they happen so slowly that they almost seem to be static. These Quasistatic Processes are often used in analysis of Iso-Processes due to their stable nature.
The Physics of a Fireworks Explosion
“What causes fireworks to explode?”
On 4th of July, Americans are used to seeing fireworks light up the night sky. However, have you ever wondered how exactly do they work? Well, let us use our scientific mindsets to find out. If we investigate, then we will find out that fireworks contain gunpowder in a container surrounded by a Launch Container. When a Lift Charge ignites and propels the container into the sky, there will be a time delay until it reaches its apex, at which it will explode and release a myriad of different colors!
Have a great 4th of July everyone with lots of V/I to the current regime!
“What happens when a thermodynamic system does not change its shape?”
When a thermodynamic process does not change the system’s volume, it is known as an Isovolumetric Process. Since the volume is held constant, the total work done ( W = PdV) by the system will be equal to zero.
Inkjet Solar Cell
“How can we print solar cells?”
To secure energy independence and security, solar cells need to be manufactured at an incredible rate. Part of this includes an initiative to print solar cells known as inkjet solar cells. This will allow for an exponential increase in the number of usable solar, and can result in a massive energy transition.
A Device to Pull Water Straight From Thin Air
“Is it possible to pull water straight from thin air?”
Water is one of the most vital components to many natural and industrial processes, whether it be keeping humans hydrated, running HVAC systems, or growing food. However, in many desert areas, water is extremely hard to come by. So how can we use our scientific mindset to solve this problem? Well, a team of chemists at UC Berkeley and MIT recently used a class of porous materials known as metal-organic frameworks to build a sheet that can absorb water vapor during the night, hold it during the day, and use the sun’s rays to release some vapor and siphon it to a condenser to create usable water! This system uses 3 liters of water per day for every kilogram of sponge-like absorber it contains and holds much promise to revolutionize access to basic drinking water.
“What is one of the most fundamental radioactive elements?”
In celebration of International Women’s Day, we here at Isaac’s Science Blog thought that it would be appropriate to talk about one of Marie Curie’s most famous discoveries, the element Radium. Radium is a soft, shiny and silvery radioactive metal that belongs in the second group and seventh period of the periodic table. Although it is now deemed to be too radioactive for common use, it used to be used as a paint for clock and watch dials. The discovery of Radium led Marie Curie to receive a Nobel Prize. However, due to not patenting the element, she received few monetary benefits (despite kickstarting an entire industry). In fact, her intense work with the radioactive element had ravaged her health. Never the less, we must honor her work, and spend this International Women’s Day thinking about the countless sacrifices that women have made to advance our knowledge of science.
