Nanotechnology is the engineering of functional systems at the molecular scale. The study and building of matter and molecules is involved. This happens at the scale of 0.1 to 100 nanometers. A nanometer is a type of measure and an idea of is its equivalence would be a strand of hair which is 50 000 nanometers in terms of diameter and a nylon fibre which 30 000 nanometers. This should give a clear picture of how small a nanometer is. Particles of a few to or hundreds of nanometers in terms of diameter have some distinctive physiochemical and surface properties and that allows them to offer themselves to innovative uses like water treatment, medicine, energy, agriculture and many more.
Water purification using nanotechnology is a very complex

To add to that, using nanofilters is also more efficient and they have extremely large surface areas and can be easily cleaned when compared with conventional methods.
Carbon nanotubes have been shown to have an equal or faster flow rate in comparison to larger pores. This could be because of the smooth interior of the nanotubes. Nanofibrous alumina filters and other nanofibre materials remove negatively charged contaminants at a faster rate in comparison to conventional filters. The negative contaminants include the likes of viruses, bacteria, organic and inorganic colloids. In both examples the advantage of using nanotechnology was of course the faster flow rate.
Risks that are associated with the use of nanotechnology procedures to purify water include; this procedure being quite costly. Since this form of technology is still new and not so many companies are manufacturing the membranes this could possibly be an expensive endeavour. On top of that the membrane filters are going to have to be changed regularly depending of course on the level of contaminants water.
For different nanotechnology procedures there are disadvantages and these will be listed

The reliability of this is not that high however everybody needs to start somewhere in order to achieve something great. I feel like the reliability of this is quite average because prior knowledge as well as extensive research was used to try find solutions to a long term problem. This was enough to get us to the answer of nanotechnology and with more testing and research then the methods that led to the arrival of this solution will be classified as appropriate and
The process of filtration can be used seeing as the copper particles will be caught by the filter because they are too large to pass through it, while the aluminum chloride particles are small enough to pass through the filter. In order to filter the products, one needs to obtain a funnel, filter paper, and a clean
All matter is made of particles called atoms. An atom is smallest unit of matter. A matter can be solid, liquid or gas. When a group of atoms bond together this makes a molecule. The molecule is the base of chemical compounds that is involved in chemical reactions.
Filtering, evaporating, centrifuging, and decanting something will only physically change it. Chromatography is used to separate different parts of a solution so that it can be identified. It can work because different substances have different attractions to things. Distillation can separate substances, such as salt water, as long as it has different boiling points. It can even be used to purify salt water but it is not cost efficient or energy efficient so it is not suitable for everyday use.
How likely is the procedure or guidelines of the innovation very clear? 4. How likely is the innovation very compatible with the existing work procedure? 5. How likely will the results of using the innovation be very observable for healthcare workers?
28 Oct. 2015.) Luckily, now people have done great researches with advanced technology that answer some doubts we have of the world now and years
Atoms DBQ Atoms make up every object , substance, and material we know of(O.I). An atom is the smallest particle an element can be divided into. An atom has a complex structure, and the knowledge we have of it has changed many times throughout history. This tiny maze of parts has helped us learn important ideas about the structure and study of microscopic particles(O.I).
Reliability: I decided to pick this Journal article manly, because
This average reliability has been shown in the first miranda test, being quite different from its other tests. Secondly, we had two different people shaking the cans, this is not reliable since different people have different strengths. If a boney and weak man shook a can compared to a body builder, the body builder is often going to be able to keep shaking the can hard at a constant rate compared to the weak man which may result differences in result. The tools we have used has also effect our reliability. The measuring tape we have used is better than a ruler, stretching up to 3 meters, therefore making it reliable, its only weaknesses is that we have to determine where it ends on the tape and it is not always straight.
However, are the results of a polygraph accurate? Depending on our perspective and research, we support the results of a polygraph are not reliable enough to be evidence of criminal investigation. The use of a polygraph has been widely accepted in the world and people use polygraphs to detect
The advancement in science and technology has helped to improve the healthcare services tremendously; beyond what even doctors thought was impossible years ago. Technology has also improved the understanding of illnesses and the development of new treatments. Up to date, healthcare scientists and doctors are still working hand in hand in trying to develop new technologies in order to improve the healthcare services as well as offer the best and most appropriate treatment to patients in the future. Advancement in healthcare has been observed fields such as pharmacology, oncology, neurology, psychology, however, for the purpose of this assignment, part one will focus on advances in medical diagnostics, bioinformatics and reproductive health.
I love the idea of the new water. I think this is a viable option that can be applied to daily life. The water is clean and drinkable. From my own life, when I lived in India and we needed to get water we would use similar methods using rocks so the water was filtered and clean. The only hard point of this initiative would be to try and sell it to the general public.
This essay will look more on the advantages and disadvantages of genetic engineering. Genetic engineering has some advantages. Firstly it allows for faster growth rate .Genetic engineering allows of plants or animals to be modified so their maturity can occur at a quicker pace outside of the normal growth conditions that are favourable without genetic changes as well .Secondly, it may also provide a cure for disease to improve health (apecsecadmin, 2014). Genetic engineering can be used to eradicate a number of incurable and deadly disease which could be done by identifying the genes that cause these disease, and manipulate them to prevent people from contracting these potentially deadly diseases.
Even if it might provide us incorrect data or if there was a problem in the process of application, this can later be opted out and people will know what is not right and hence could search for alternative methods. Moreover, the field of Natural sciences has been based on paradigm shifts. Our knowledge of what was previously regarded as the absolute truth has been turned out to be false several times and has been replaced by relatively “more perfect” knowledge. Therefore, even if the results obtained through application could lead to results that is not in accordance with people’s expectation, this, in the long term, can possibly lead to progression of knowledge that is much closer to the absolute truth and hence the extrinsic value of knowledge will increase through
When reaction conditions are changed, you may shine light on new possibilities, which can lead to disproving of a hypothesis or the conception of a new one. Sonnenburg et al. claim that reproducibility of experimental results is a cornerstone of science. 3 They state: “In many areas of science it is only when an experiment has been corroborated independently by another group of researchers that it is generally accepted by the scientific community”.
