Nanochemistry: Beautiful Nano-Flowers
Who knew the beauty of nature could be chemically created? Intricate nanostructures bloom from a chemical reaction created at Harvard. As said in the article Beautiful Nano-Flowers, “By simply manipulating chemical gradients in a beaker of fluid, Wim L. Noorduin, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS), has found that he can control the growth behavior of these crystals to create precisely tailored structures.” With Nanochemistry, the most delicate flower structures are created, “though not to the scales of inches, but microns.” Though they are made from crystals, the tiny sculptures are curved and delicate, so they do not look like the sharp or cubic forms generally associated with crystals. As Noorduin says in the article, “For at least 200 years, people have been intrigued by how complex shapes could have evolved in nature. This work helps to demonstrate what's possible just through environmental, chemical changes.” Nanochemistry, which is “the scientific branch that examines the synthesis, analysis, and structure of chemical compounds at the nanoscale,” helps create these complex, beautiful structures, but can be used for so much more.
Depending on the reaction of compounds spreading through the liquid solution, the precipitation of crystals varies. As the article reads, “The crystals grow toward or away from certain chemical gradients as the pH of the reaction shifts back and forth. The conditions of the reaction dictate whether the structure resembles broad, radiating leave...

...ields of coral and sponges. Sometimes I forget to take images because it’s so nice to explore.” Although the science of Nanochemistry can be used to create beautiful works of art, the applications of Nanochemisty are not as exciting, but very important. For instance, “The folds of these 3-D microstructures pack a large amount of surface area into a tiny space—an important consideration for the production of chemicals that depend on catalysts, substances that speed up chemical reactions. The more surface area available, the more catalysts you can add—and the more efficient the reaction.” The applications for this would even help the environment by using “Nanomaterials” to create sensors that will detect specific molecules and these detectors can be used in the applications of detecting and “monitoring pollutants in water.”
What chemistry can create is fascinating.
Amandi Hiyare: Before forming my research question, I had a discussion with my research project coordinator “Lisa Pope” who told me that the Flinders nanotechnology research team has been developing microbial catheters. Then on Monday I had an interview with Professor Joe Shapter who told me that your team was leading this project. So I was wondering whether you would be able to provide me with some detailed information about this innovation?

Miodownik describes in detail how natural elements were manipulated by man to create man-made materials at the same minuscule scale that take place naturally. Materials science has provided the knowledge required for
A precipitation reaction can occur when two ionic compounds react and produce an insoluble solid. A precipitate is the result of this reaction. This experiment demonstrates how different compounds, react with each other; specifically relating to the solubility of the compounds involved. The independent variable, will be the changing of the various chemical solutions that were mixed in order to produce different results. Conversely the dependent variable will be the result of the independent variable, these include the precipitates formed, and the changes that can be observed after the experiment has been conducted. The controlled variable will be the measurement of ten droplets per test tube.
8. Continue stirring. Record the temperature at which crystals begin to appear in the solution.
Water (125 ml) was added to the solution then cooled in an ice bath for 10 minutes. The brown crystals (2) were collected by vacuum filtration and dried (2.407 g, 5.37 mmol, 90.3%
It is clear that nanotechnology has the potential to revolutionize health care and even transport
The story commences with Myop skipping outside her house enjoying the beautiful weather and summer air “the air held a keenness that made her nose twitch (Walker)”. For a while Myop continues to play and sing on the farm, just like a young girl would; with absolutely no worries “Nothing exist for her but her song (Walker)”. The causative incident occurs when Myop decides to explore the woods behind her house and ends up discovering “various common but pretty ferns and leaves, an armful of strange blue flowers with velvety ridges and a sweet suds bush (Walker)”. The rising action begins to arise around noon. Here, she has an arm full of her findings and realizes she is far from home when she senses an eerie change in the atmosphere. The climax emerges when she decides to find her way home. Myop suddenly gets her foot caught in something and she bravely pulls her it free, before looking at the demolished face below her. The falling action is revealed when Myop realizes what she stepped on. She detects the rest of the body and finds evidence that suggest the man was lynched to death. At this point she lays her flowers down and Walker introduces the readers to the main theme by concluding the short story with “And summer was over (Walker)”.

In our experiment we utilized the hydrate cobaltous chloride. Hydrates are crystalline compounds in which one or more molecules of water are combined with each unit of a salt. Cobalt (II) chloride hexahydrate is an inorganic compound which is a deep rose color in its hydrated form. As an inducer of
In the novel, Prey, written by Michael Crichton it pertains to the subject of nanotechnology throughout the whole entire book. The main characters of this novel are the
The main purpose of green nanotechnology has been to develop clean technologies that would minimize potential human and environmental health risk. Also, to encourage replacement of existing products with the clean technologies that is more environmentally friendly. There are many benefits of using green nanotechnologies as the new solution for energy in both their current availability and their current development. Over the new few decades, the highest growth opportunities will come from application of nanomaterials for making better use of existing resources. Nanotechnologies will help reduce weight of carbon emission in transportation utilizing nanocomposite materials that quickly diffuses across the automotive and aerospace industries. Applications of nanotechnologies will result in a global annual savings of 8000 tons of carbon dioxide, which will rise even further to over millions tons by 2020. But, let’s focus on the positive effects of Green Nanotechnology in Solar.
I have chosen nanotechnology as my topic area of choice from the food innovation module.
The most interesting part of this career is developing nanotechnology. They may cure diseases or slow the aging progress. Most nano-devices are as small as 100 nanometers across so, they are built on the atomic scale. If put into the human body and designed pro...
