An ultrasonic nebulizer is a small, portable device that uses ultrasonic sound waves to break liquid particles down into a fog so that they can be inhaled easily. Patients who have asthma, COPD, pneumonia, chronic bronchitis, emphysema, or other chronic conditions, most often use them for medicinal purposes. While other devices can deliver the medicine …
A bucky ball is a fullerene molecule which is any molecule that is made up entirely of carbon. Specifically, a bucky ball is a spherical fullerene while the cylindrical fullerene is called a carbon nanotube. They were discovered in 1985 and are referred to, chemically, as C60. When they were discovered, it expanded the number …
Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field …
Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in …
There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and …
