Microelectromechanical Systems (MEMS) are systems that are designed on a micro metre scale and have

Whenever a monolayer is attached to a metal surface, the wetting properties and behavior can be significantly affected (Yuan & Lee, 15). In practice, densely-packed self-assembled monolayers (SAMs) can be used to modify the macroscopic properties of a solid surface (Dilimon et al. 202). Changes in wetting properties occur due to changes in the angle made by a liquid droplet whenever it is in contact with the surface. This phenomenon is significant in several contexts for example, in industrial contexts: this property is used to evaluate the cleanliness of semiconductor wafers. In such contexts, contact angles measurements are widely used. Control of this property is also useful during penetration of insecticides or pesticides into plants, and waterproofing of materials (Yuan & Lee, 25). While the former focuses on maximization of wetting, the latter case seeks to minimize liquid-induced wetting (Yuan & Lee, 28).

Diamonds are very unique. Their hardness and beauty have enticed people for many years. Now some of the same attributes that make them appealing also make them useful. To understand these attributes the chemistry of carbon is very important. This unique chemistry is what makes them so hard to make. Much research has gone into the making of diamonds and this has led to many successes in the field. These discoveries have led to machines and processes that make diamond making more efficient and reliable. Of course, all of this research and discoveries would not be sought after if it was not for the many applications of diamonds. This is true for cosmetic, industrial and

The use of nano-materials and extreme precision micro-engineering has the potential for great improvement in the world of electronics and information technology by providing smaller, faster, and more powerful computers and this has been at the forefront of the nanotechnology commercialization . Great examples of how nanotechnology is currently being used in these fields are products such as processors, data storage, and memory components made with nano-materials, TVs, monitors and even smartphone screens that use organic light-emitting diodes (OLED), and waterproof electronics such as smartphones due to the application of nano-coatings

Johnson (2006) eloquently talks about healthcare systems as “cumbersome, unwieldy, unfriendly and opaque to its users” (Johnson, 2006, p. i10). It is the challenge of this post to take the clinical microsystem where I practice, the HIV Health Service Center clinic, and discuss the interrelationships of this microsystem to the microsystems of other primary care clinics in the county system. The main role of the mesosystem is to support the microsystems. According to Bronfenbrenner’s ecological system’s theory, the mesosystem contains the relationship between two systems, or between the primary care clinics in the county system and the macrosystem which contains both the microsystem and the mesosystem. Moreover, the Multnomah County Health Department could be identified as the macrosystem here or we could identify the larger state system as the macrosystem. Communication between systems is an area that could be enhanced to improve overall functioning of the clinics.

Diamonds are essentially made out of carbon atoms. They are solids that can go through the process of high temperature and high pressure. (Pilgrim, 2011) It is known to man that diamonds are the hardest material on the earth. (Sean, 2008) With a melting point of 3550 ℃and a boiling point of 4827 C. As you can see above that diamonds have an extremely high melting point (m.p) and a high boiling point (b.p.) The pressure to produce diamonds are also in extreme conditions, diamonds are produced with a temperature range of 900 and 1300 degrees Celsius. Then put under pressure of 725,000 pounds per square inch. (World of Carbon, n.d.) Diamonds have these properties

Consequently, Bernoulli took Newton’s three truisms of solid behavior to explain the wafers pushing each other through the tube and mixed it with Leibniz’s calculation to “add up infinitude of wafer to wafer interactions” (Guillen 101). As a result, Bernoulli was able to apply the Vis Viva formula, which his father had told him only applied to solids, to a liquid. The main difference was that instead of altitude, it is measured in

Thesis: The extremely strong chemical structure of diamonds contributes to its unique chemical and physical properties, which allow diamonds to be used for a variety of practical applications.

According to Gibilisco, piezoelectricity is an ability to generate a current when it undergoes to stress or vibration. Feitscher said that piezoelectricity is the appearance of positive electric charge on one side of certain nonconducting crystals and negative charge on the opposite side when the crystals are subjected to mechanical pressure. Piezoelectricity was used on devices such as microphones, phonograph pickups, and wave filters in telephone-communications systems

= −2.088 GPa (compressive) [43, 44]. Diamond has a face-centered cubic lattice with space group Fd3m. It has two carbon atoms in the primitive unit cell, and thus a single triply degenerate firstorder phonon with symmetry F2g [45–47]. The single sharp Raman peak at ~1332 cm−1 is assigning to these F2g modes at the center of the Brillouin zone of the cubic diamond. The importance of the ~1332 cm−1 characteristic in the Raman spectra of polycrystalline diamond films is as a valued indicator of the relative sp3 carbon content.

Diamond is the hardest material known to man, in this day and age. Typically, diamonds have been known to demonstrate hardness values up to 12000 HV (Vickers Hardness) or approximately 100HRC. Diamond-coated Tungsten Carbide tools have demonstrated improved machining characteristics over coated tool steels commonly used today. With the increased use of composites, ceramics, and other ultra-hard / lightweight materials in numerous industries, diamond-coated machine tools are becoming more common since their performance improvements generally out weigh their increased cost.

Ferro-electrics are an important class of materials which posses excellent electro-mechanical coupling behavior \cite{jayendiran2012modeling}. These materials have been used in sensors, actuators, biomedical and naval applications for several years. These materials behave linearly under low electric fields and mechanical stresses, but show nonlinearity at higher electric fields and mechanical stresses; see the review articles \cite{kamlah2001ferroelectric,landis2004non,huber2005micromechanical}.

Diamond has a Face centered cubic structure. This arrangement makes the diamond toughest, high thermal conductor & gives optical diversion properties. The substitution of carbon with boron in diamond lattice improves the electron m0obility in the structure. Nanodiamonds are smoother than microcrystalline diamond which ranges between 10-100nm. Nanodiamonds are often termed as ‘cauliflower’ or ‘ballas’ diamond. They contain large number of grain boundaries with impurities of graphite. Even ultra naocrystalline diamonds have a grain size of 2-1nm [4].

The memristor (pron.: /ˈmɛmrɨstər/; a portmanteau of "memory resistor") was originally envisioned in 1971 by circuit theorist Leon Chua as a missing non-linear passive two-terminal electrical component relating electric charge and magnetic flux linkage. Leon Chua has more recently said that the memristor definition could be generalized to cover all forms of 2-terminal non-volatile memory devices based on resistance switching effects and Chua has said that the memristor is the oldest known circuit element with its effects predating the resistor, capacitor and inductor.
