Cathode ray

In recent years, modern Li-ion batteries (LIBs) have become ubiquitous power source for a variety of applications such as laptops, mobile phone, and digital camera to electric vehicles, owing to their high power density, high energy density, and long cycle life.1–3 However, there are still many critical challenge to increasing the energy, power density, and improved cycling stability.4–6 In particular, selecting noble electrode materials is the hottest topics in the LIB field. Among them, bulk…

Thesis for Research Paper Throughout life, there are certain technological advancements everybody experiences which affect their lives in either positive or negative ways. To be more specific, the field of photography is a field which has had some major technological advancements with imaging, resulting in the discovery of radiographs, computed tomography and magnetic resonance imaging. The chain reaction of advancements from photography to medicine has helped the world in increasing life…

viewing. The development of the electron microscope in the 1930s revolutionized biology, allowing for organelles, such as mitochondria, to be seen in detail for the first time. Unlike light microscopy, TEM uses a beam of electrons, denoted as a cathode ray, to scan samples. While the traditional optical microscope is restricted in resolution by the wavelength of…

Labradorite has such a mystical appearance, it can seem like such an ordinary looking rock but with just a slight tilt of your head, the most beautiful flashes of colourful light appear. It is no wonder that this mystical appearance has inspired legends and was used in healing potions by the Inuit people of Labrador. As a fashion accessory it’s grey/iridescent color makes it a great item to go with just about any attire. Labradorite Physical Properties What is Labradorite? Labradorite is…

X-Rays Development of the X-Ray In 1895, a mechanical engineer and physicist named Wilhelm Roentgen created the X-ray. He was born on March 27, 1845 in Germany. So in 1895, Roentgen was playing around with a cathode ray tube and evacuated all the air inside of it and replaced it with another special gas. Then, he covered the tube so nothing escapes it, passed a current through it, and then the tube produced a fluorescent glow. After further investigations, Roentgen wanted to see how strong this…

The X-ray, also called the Röntgen ray, was invented by German scientist Wilhelm Conrad Röntgen in 1985. The x-ray is undisputedly important and is used todays at airports and sporting events to check for weapons and dangerous substances and at hospitals in order to check for fractured or broken bones, internal damage, or items lodged in the digestive system. Despite the x-ray’s numerous and various uses, it’s discovery was unintentional. Wilhelm Röntgen discovered the x-ray while…

X-rays is one type of electromagnetic radiation that can send waves through the body which makes us see through the body tissue but it doesn’t go through the bone. Therefore it is used in hospitals to see if a person has a broken bone or any diseases. Because it can go through clothes and the human skin it is also used in airports to see if anybody has a knife or anything dangerous with them. X-rays were first discovered by German scientist Wilhelm Conrad Roentgen in 1985. Roentgen found x-rays…
