      Dielectric Constant

      A dielectric constant measures the extent that a material concentrates electrostatic flux and is also known as the relative static permittivity, static dielectric constant, and relative dielectric constant. It is essential when determining if a substance can be used in a capacitor or various chemistry and physics applications. A material’s dielectric constant value must be

    • Acrylic Adhesives

      Acrylic Adhesives

      An acrylic adhesive is a resin-based adhesive that is comprised of acrylic or methylacrylic polymers. It is rather complicated to produce acrylic adhesives as they must be formed into a polymer, suspended in a catalyst, and cured. Acrylic adhesives are very strong and efficient at bonding multiple objects together. They are resistant to sunlight, not

    • Why is Geography Important?

      Why is Geography Important?

      While many of us labored to learn geography in school, we always wondered why it mattered. Here are some reasons why a sound understanding of geography is more important today than ever before. Politics We live in a world that is shaped by the political climate in various locations around the globe. In order to

    • What is Phosphorescence?

      What is Phosphorescence?

      Phosphorescence is an effect in which some chemicals re-emit light that they absorb. It is similar to fluorescence, except that the chemical reactions within phosphorescent materials happen less often, thus they take longer to emit light. Phosphorescent materials can be recharged by being exposed to light and may store light for several hours before it

    • How Blizzards Form

      How Blizzards Form

      Blizzards are severe storms which are marked by extremely low temperatures, high-speed winds and substantial snowfall. They are formed when a region of high atmospheric pressure, termed as a ridge, interacts with a region of low atmospheric pressure. As a result of this, a phenomenon known as advection takes place, in which there is a

    • How Do Nuclear Power Plants Work?

      How Do Nuclear Power Plants Work?

      A nuclear power plant works in the same way that a coal power plant works. Heat is generated which causes water to turn into steam. This steam turns a turbine which causes a generator to spin which generates electricity. However, a nuclear power plant does not use coal. Instead, the fuel of choice is uranium

    • What Causes Radioactivity?

      What Causes Radioactivity?

      Radioactivity is caused when an atom, for whatever reason, wants to give away some of its energy. It does this because it wants to shift from an unstable configuration to a more stable configuration. The energy that is released when the atom makes this shift is known as radioactivity. In other words, radioactivity is the

    • What is Acesulfame Potassium?

      What is Acesulfame Potassium?

      Acesulfame potassium (Acesulfame K or Ace K, where “K” is the elemental symbol for potassium) is commonly used as an artificial sweetener or flavor enhancer. It is used in low calorie food products as it replaces sugar and other natural sweeteners that commonly add large amounts of calories. Acesulfame potassium’s trade names include “Sunett” and

    • Vulcanized Rubber

      Vulcanized Rubber

      Vulcanized rubber is a material that undergoes a chemical process known as vulcanization. This process involves mixing natural rubber with additives such as sulfur and other curatives. Vulcanization makes rubber much stronger, more flexible, and more resistant to heat and other environmental conditions. Vulcanized rubber makes both soft and hard objects, ranging from rubber bands

    • What Are Ferrofluids?

      What Are Ferrofluids?

      A ferrofluid is a metallic liquid that becomes magnetized when placed in a magnetic field. Ferrofluids are made up of clumps of iron nanoparticles that are evenly placed throughout a carrier fluid such as water or organic solvent. These clumps all work together to create a response to a magnetic field, consequently creating a very
