Radiation Exposure in Electronic Devices

Have you ever heard of a nuclear disaster? Some famous examples are the Three Mile Island accident, the Fukushima Daiichi nuclear disaster, and the most commonly known, the Chernobyl disaster in 1986. Nuclear disasters are classified as accidents in which radiation is huge doses is released into the Earth. They are extremely deadly and just a tiny bit can cause flu-like symptoms, cancer, or even death in some cases.

A ceramic insulator found in many electronic devices such as cell phones and fitness trackers glows under high heat, which reveals the amount of radiation exposure on it. This could allow doctors to estimate how much radiation a person has been exposed to in a matter of hours instead of days.

When nuclear radiation comes into contact with the ceramic in electric modules called surface mount resistors, the radiation causes the electrons in the ceramic’s structure to rearrange themselves. Once heated to a couple hundred degrees Celsius, the material glows, revealing the new distribution of the electrons. Scientists can then determine the amount of radiation exposed to based on the new layout of electrons. This test can determine whether someone needs immediate attention for radiation poisoning, and if the user has an increased risk of cancer.

In the long run, this new material could be modified to even determine other amounts of dangerous substances, such as cocaine, chlorine, and other gases. Although the price tag is very heavy, new materials could be found that would be more widely available to the public, as most people don’t have $150,000 to shell out on a daily basis.

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
