Community involvement provides a setting where we develop the skills and attain the knowledge that will help us make a difference in our vast shifting society. It endeavors to provide us opportunities to make choices and stimulus to content our academic needs conscientiously and successfully. Being involved in the Charity Club at my school has enabled me to do my share regarding community service. In the Charity Club we organize meetings where we come up with different projects , and then we find
as a separation and purification technique and in the production of pharmaceutical solid forms3,4. Knowledge of the crystal structure allows the crystal engineer to know and manipulate the chemistry of the crystal in order to optimize exact characteristics performance 3. Furthermore chemical and physical properties of a material are dictated by crystallization process. The crystal properties such as: particle size, shape, surface characteristics, purity and defect structure, as well as thermodynamic
If you trace back the steps of the origins of chocolate, it has been around for more than about 2000 years when chocolate was used as a bitter beverage for the Aztecs. Further more you will be reading about the origins of chocolate, the types of crystals that form while trying to temper chocolate, problems while tempering chocolate, and the process of tempering chocolate. This is everything
Chapter 3 Agile Methodology 3.1. Overview Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change. Agile development is chosen when the requirements are not clear. This is

therap: to use/to care for and chroma: color. Color therapy, also known as chromotherapy, is a way of curing diseases with the use of color and light. This method has been used centuries ago and is still being used today. There are many methods of color therapy and there are many items used in it. These items are gemstones, candies, lamps, crystal pyramids and wands,... ... middle of paper ... ...rks buy using colored light and acupuncture points on the skin to energize our physical and energy

This frequency is generally used to keep track of time (as in quartz wristwatches), to provide a stable clock
the appearances because both have same basic physical and chemical properties. There’s only a way to differentiate between natural and synthetic diamonds which is by studying their impurities both microscopic and atomic level. There are several methods used to produce synthetic diamond which
1) Achievement of supersaturation or supercooling 2) Formation of crystal nuclei 3) Successive growth of crystals to get distinct faces Ostwald’s Diagram Ostwald was appeared to be the first to explain the relationship between supersaturation and spontaneous crystallization. The relationship between the concentration and temperature is schematically shown in Figure 1. Extensive research has been carried out to explain the relationship between supersaturation and spontaneous crystallization
the crystallization it doesn't turn to ice, no matter how cold it is. Although, in everyday life there are seed to trigger crystallization. The answer to why this works can be found in the physics of crystallization. To form a crystal you need something that the crystals can grow around a, nucleus of regularly arranged atoms (Science in school). Crystallization occurs most often when a liquid touches a solid surface or when the liquid contains crystalline impurities. It is kind of like the liquid
Fashion trends change from time to time and so do nail art trends! The most fascinating nail art design that is currently in-vogue around the globe is quartz nails. And you guessed it right, it is inspired by the mesmerizing quartz crystals. This nail art design has been doing rounds of Instagram and other such social media platforms since mid 2017. Even though 2018 has arrived with a lot of other new nail art trends, we are pretty sure that the quartz nail art trend is not going anywhere anytime
acrylic glass material. With this creation they were able to prove that PBG materials are capable of propagating electromagnetic waves. What are Photonic Band Gap materials (PBG)? Photonic band gap materials (PBG), also known as photonic crystals (PC), were formerly introduced as a way to manage the optical properties of certain materials. PBG materials are artificial, dielectrics that have a periodic composition of permittivity. It was discovered that we could not only obtain frequency
hydrate of CuSO4 by heating the crystal to dryness. The success of the lab will be determined by how accurate the experimental formula is compared to the actual formula. Theory If heat is applied to Copper (Ⅱ) sulfate pentahydrate, then the experimental form will be equivalent to the theoretical formula. Important key data that will be needed to achieve the goal of the lab experiments includes the initial mass of hydrated crystal, the final mass of anhydrous crystal, the
electronics will have crystals in their construction somewhere. From microchips with super-storage or photon-processing crystals, crystals will be everywhere. And they already are. Crystals are used in color changing paint and even in the touch screen of smartphones. Many famous scientists are researching crystals and how they could be used. Crystals are natural wonders of nature that are built in complicating and amazing structures that have the potential to be used everywhere. “[Crystals are a] homogeneous
heating. This information is used to find x in the formula: CuSO4.xH2O. Note that x must be an integer (a whole number). Diagram Method Safety: Wear eye protection Find the mass of your crucible. Place 2–3 spatulas of blue copper(II) sulfate crystals in the crucible and weigh. before Heat until the crystals have gone completely white, but do not heat so strongly that they start to blacken. Allow to cool then reweigh. after Once you have made all
hydroxide and crystal violet using spectroscopy. Graphical methods will be used to determine the kinetic rate law, rate constant and activation energy for the reaction. General Discussion: The order of hydroxide was determined by the varying the initial concentration of hydroxide in runs 1 and 2. We used the isolation method, which calls for having much higher concentrations of one reactant then the other, in this case the concentration of NaOH being much higher than the concentration of Crystal Violet
Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite exhibits birefringence
Testing the Suitability of Using Alum Synthesis as a Method of Recycling Aluminum Introduction: According to The Aluminum Association, “Americans throw away nearly $1 billion worth of aluminum cans every year” (The Aluminum Association,2014). With the increasing number of aluminum cans being disposed of in landfills annually, it is important to investigate ways to cut back on waste and how these products can be recycled in the most efficient way possible. The purpose of the lab was to further
velocity field, stream line, Peclet numbers and Reynolds numbers in Si melt are performed for directional solidification crystal growth processes. One of the greatest technological and scientific challenges of multi-crystalline silicon growth is to achieve homogeneity of the material properties in the grown crystal. It affected by fluctuations of the growth rate of the crystal. One of the possible causes for fluctuations of the growth rate is the instationary convection in the melt. The aim is to
