Question 5 How would you compare a MEMS electrostatic actuator versus a thermal actuator in biomedical applications? Use appropriate physical, thermal and/or empirical models where necessary. As microelectromechanical systems (MEMS) become more prevalent, including in biomedical applications and more specifically in applications relating to movement of electrodes, it is important to examine some of the most common actuators used to accomplish this task, specifically electrostatic and thermal actuators

Welcome campers back to The Science of Superpowers! Before getting started, grab your mask, find your camera and hold on tight as we swing through New York City seeing what everyone knows about Spider-Man. How did he get his powers? What’s his real name? What abilities does he share with spiders? Add to the conversation by either reading directly from the Background Information or by ad-libbing in your own words and get everyone excited about web-swinging with their Friendly Neighborhood Spider-Man

John Dalton was born in September 5th, 1766 in Eaglesfield, England (Brooklyn.edu). John D. was born color blind and he’s the first person to study the color blindness. He is also credited with pioneering modern atomic theory. He has revealed the concept of Daltons law of partial pressure. He is the first scientist to discover about the behavior atom in a term of the measurement of weight. While in early career as scientists he researches about color blindness because he was born color blind. Since

How fuel cells work A fuel cell is a device that produces an electrical current through a chemical reaction. All fuel cells contain a cathode and an anode, which are positive and negative electrodes, respectively. The chemical reactions which produce electricity occur at the electrodes. Fuel cells also contain an electrolyte, which carries electrically charged particles between the electrodes. A catalyst also aids to speed up the chemical reaction at the electrodes. In fuel cells, an impurity must

and called it the “Saturnian” model because he thought that opposite charges are impenetrable. He then arranged the electrons to be surrounding the central positive charge. His model consist of a number of electrons of equal mass at the centre of the circle or in his case, the “planet”. He thought that atoms were electrically neutral and in order to maintain it, an atom must contain an equal amount of positive and negative charges. Nagaoka clearly rejected my model and I wasn’t happy about

atoms themselves are made up of charged particles: Protons which are positively charged, neutrons which have no charge, and electrons which are negatively charged. Even though atoms are neutral, charge can still be transferred through the fact that not all atoms or molecules hold on to their electrons with the same strength, and when two substances are in contact the transfer of charge can occur. In this experiment we will examine the way different objects interact and how under dry conditions some

1. What is hydrogen bond and the differences between covalent bond and ionic bond? Hydrogen bonds are weak bonds that form between the atoms of different molecules, serving to hold these molecules together on a somewhat transitory basis. A hydrogen bond is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. This is not a sharing of electrons, as in a covalent bond. Instead, this is an attraction between the positive and

Electrons in Atoms Electrons are the negatively charged particles that can be found in the atom. Electrons will be located around clouds that surround the nucleus of an atom. All Together the atom creates a negative charge that will make sure that it balances the positive charge of the protons in the atomic nucleus. These clouds are at a certain distance from the nucleus which is properly put into the shells. Due to the fact that electrons move so quickly it is impossible to see where they are

Early atomic model experiments Thomson’s discovery of the electron in 1897 and the atomic model, with his findings of the atom containing electrons, each with an individual unit of negative charge. Thomson also found that electrons were very light when compared to the mass of the atoms in which they came from. This is because atoms were known to be electrically neutral, the remainder of the atom had to be positively charged and form most of the weight in the atom. Thomson used his plum pudding model

Attending a laser light show can be beautiful, fun, and maybe even dizzying. The audience may be dazzled by the twisting and turning colors, but how much of the crowd actually knows how lasers operate? Light, color, vision, and the electromagnetic spectrum can explain how lasers and the captivating shows are possible. In order to understand laser shows, you need to understand lasers. The first working laser was created by Theodore Maiman, who placed a ruby rod, a fully reflective mirror on one end
