In our first lab, we made a ferrofluid. In this lab, we combined chemicals such as iron (II) chloride, iron (III) chloride, and ammonium hydroxide in order to create a black precipitate. The resulting solid is magnetite. The rest of the lab dealt with the manipulation of this solid using a magnet. If done correctly, the precipitate can be forced into “spiked” shapes. I have always

img_0381img_0402enjoyed doing labs and was happy to be able to do one today. For me, learning becomes so much more interesting when it is interactive. Making a ferrofluid is ten times more effective than a simple lecture.

Our second lab concerned photolithography. First, we each drew a design on transparent photomasks. Then, we placed them atop a square consisting of a photoresist, copper, and a circuit board. Afterwards, we placed them under UV lamps for twelve minutes. We dipped the circuit boards into developer solution, rinsed it with water, placed it in etchant solution, and proceeded to rinse it again. My design was a stick figure of a girl saying “Hello!” and had my name on the bottom-right.weeee-blog-six

The lecture today showed us how to “imagine the impossible.” We saw ideas for futuristic cars, virtual medicine, and new cell phones. This lecture was one of the best in that it helped us visualize how to push the limits of our current knowledge and to dream of things that may potentially better our lives in the future.

When I went to Wired NextFest last year, I played a mind game called “Brain Ball.” The objective of this two-player game is to try to get a ball to pass through your opponents’ goal on the other side. Sounds simple enough, right? The problem is that you must do this only by using your brain activity. A strap around the forehead that contains electrodes measures each player’s electrical activity. This information is displayed on a graph for everyone to see. It was so fun! I look forward to owning this game in the future.

Just two days after learning about the SEM (scanning electron microscope), I actually got to see it in action today. The first object placed under the lense was the hair from one of my group-mates. As I learned from before, the SEM can only produce black and white images, but even so, the details were amazing. I could even see the outlines of the strands of protein that made up the hair.

The next lab I visited was focused on solar power. So far, scientists have discovered a new contraption capable of producing solar power. The only

red tide

red tide

problem with this invention is that within a few hours out in the sun, it will melt. Therefore, scientists are now studying the Red Tide to try to understand how red algae is capable of producing blue light on their own. One key component that causes the algae to produce blue light is luciferase, which is activated whenever the tide comes in contact and agitates the algae. If scientists are able to make a breakthrough in research and discover how to incorporate luciferase into our daily use of energy, then just imagine how much energy we can save.

Luciferase isn’t only founded in red algae. This enzyme is also present in fireflies which causes the insects to light up. Also in the science fields, luciferase is noted to be a very handy chemical. Scientists implant luciferase into quantum dots in order to label cell parts or detect different types of cells.

Day Six-7/14/09

The concept products and inventions that were showed to us during the morning presentation were amazing. The Nokia Morph phone img_132382_nokia_morphwas really cool because it completely revolved around nanotechnology and it gave me an idea for a possible product maybe something that I’ll just throw out there. I think it would be really cool if families in developing countries could be supplied with some sort of durable computer with “sense technology” such as this, that would thermoelectric converter of human warmth have many applications, such as detecting bad chemicals in the water because I know that is a major issue; for example I read in National Geographic a couple months ago about how, following the use of chemical fertilizers in Punjab, the chemicals contaminated the waterugandan-children-fetch-contaminated-drinking-water-photo

and people are developing cancer linked to this. It would also come with downloadable virtual textbooks to promote education, interactive apps, rather like the iphone, for kids, such as a virtual keyboard that they could use to learn to play and read music where they might not otherwise get the opportunity. They could also be used to communicate with tutors from around the globe, so perhaps they could learn English and other languages, and they could also be used as medical tools for diagnosis and treatment. It would come with two portable, wearable (as a wristband), electronic devices that could communicate with the main computer, that could be used for kids to communicate with their parents and for parents to track their kids in unsafe areas. A camera in it could learn to recognize the area. It would be solar powered, or perhaps, at night and in areas without ample sunlight, by some sort of thermoelectric converter of human warmth . Many of these ideas are already possible, but expensive. There is a mission called One Laptop per Child that wants to provide an affordable laptop to every school age child in developing countries to connect them to the rest of the world. I think technology is very important to connect people and create progress. Anyways, we had a long discussion about the implications of this massive explosion of technology. Though I think it will dramatically change our world, in a greater way than even like guns because there’s so much more technology and more powerful technology being developed now, I think that humans are essentially good. I think in general technology is developed and used for want to change the world for the better. There are a lot of science fiction movies that scare us with depictions of a future where humanity is lost and everything is computer-like, and of a future where we war with the machines we created, but hopefully such things will never happen.

Spider silk

07.14.09

“They stole our idea!!!” I whispered vehemently to Amy, who was sitting next to me in the auditorium that morning. A second later, the two of us burst into giggles, seeing as Nokia’s concept had been developed a year earlier that we had even met each other.

In the first days of the Art|Sci Nanolab program, we had been sharing several random ideas for possible final presentation topics. The first among many discussed was nearly chosen, until I mentioned my longtime aspirations to be able to record dreams. That caught the group’s creative desires, so we completely dropped the first idea that had been born during a random conversation on the “Harry Potter” stairs of the C(n)SI building.

However, after watching that Nokia advertisement, I realized how lucky we were to have dropped that original idea, as it would’ve seemed to be taken straight from Nokia’s conceptual invention!

Okay, now to clarify our original ideas. I always heard that a strand of spider silk is stronger than steel of the same size. Thus, I thought that using nanoscience, one could manufacture spider silk in great quantities, using it as a resource on its own. Furthermore, spider silk is extremely durable and ductile, meaning possible condensing of the creation.

So our original idea was to create portable houses out of spider silk material, and this idea is used quite similarly in the wearable Nokia phone. As a whole, the nanoscience, spider silk structure, and pliant material are all ideas we thought we coined, but ended up previously in existence.

It’s hard to be original these days.

Ferrofluids

ferrofluids31 It was so cute.  Black in color and extremely smooth to the touch, we gazed in the adoration as it playfully traveled around the little blue plate.  Our precious ferrofluid.   We were proud.

 

 

            Today was essentially the very first time we got to “get our hands dirty”, this expression in our case being far from metaphorical.  Creating nanotechnology is very different fom listening about nanotechnology eing created, and we all enojoyed the opportunity to do so.  It turns out that nanotechnology does not necessarily have to be this impossibly expensive and inaccessible type of mechanism; to the contrary, it is something that anyone can make using some chemicalsferrofluid.

 

            As I mentioned the particular type of nanotechnology that we created was a ferrofluid- or a colloidal suspension of magnetic nanoparticles.    It was pretty baffling to see a fluid respond to a magnet- moving instantly after it and spiking up periodically as if it were a living thing.

 

            Of course it was fun to watch, but there are so many directins that this simple fluid can take people.  Maybe thisferrofluids2 seems completely ridiculous but maybe we can easily construct cars and other technology using ferrfluids.  Imagine a room full of strategically arranged magnets and little faucets on the walls.  As the faucets spew ferrofluid the magnets manipulate its flow in a way that self-assembles an entire vehicle in minutes.  That could increase production efficiency because the need for humans in the process would be mostly eliminated.  Likewise this technology could be applied on a smaller scale to build such useful things as toasters.

 

            Doubtless there are more practical things to be done with ferrofluids such as localized medicine delivery that could potentially be used to treat and cure many diseases.  However this is so practical that it is already being done and hopefully we may see the benefits in our lifetimes.

Day 6

Today during our lecture we got to see a lot of different types of concepts for new inventions. This eventually led to our long discussion on the ethics of new technologies. There was a lot of talk about new inventions eventually leading to dangerous weapons or the destruction of the human race, but I also thought it would be important to think about the smaller side effects of new inventions. While it would be kind of ridiculous to think that any small new item could lead to the death of all humans, it would not so out there to consider the smaller effects on human behavior. For example, the use of cell phones have lead to a both an increase and a break down in human communication. Although now we can talk to any of our friends at any time or location, we tend to talk less to the people around us. If I was on a long bus ride, I would probably use my cell phone to call a friend to pass the time. However if they didn’t exist, I would have probably tried to strike up a conversation with the person seated next to me. The invention of a cell phone might have cost the loss of new acquaintances and friends. Futhermore, the invention of texting has probably led to less talking too. People now result to just sending short, simplified messages rather than holding an actual conversation.

Nevertheless, I beleve that these inventions are very beneficial. I personally think the pros usually outweigh the cons, yet I think that we should still be aware of the negative consequences on society, no matter how small or subtle. The cell phone has probably saved lives in emergency situations or just made everyday life easier, but it has affected social behaivor in what can be considered negative ways.

I think that our fears shouldn’t get in the way of new ideas and creations, but that we should always consider the possibilities and risks before inventing anything new. It’s hard to define the line between what is ethical or not, and while I don’t have any answers, I think that it is a topic of discusson that should never end as we get imput from all people of different experiences, careers, and generations.

Today in the lecture, a video was shown that presented a new idea to us.  The idea of the double split, particle motion, and probability of patterns matter makes is easy to understand and predict at the meter level. But when minimized to quantum level, the physics change.  The electrons travel through the slit in random ways, and somehow still make a highly dispersed wave pattern.  This is confusing in itself, but then once a device that watches the slit is installed, the electrons behave as expected, not as usual.  This proves that just a watcher can affect the action at the quantum level.  This amazed me.  I still can barely fathom these hypotheses and conclusions about quantum physics.  But I am intrigued and am hoping to take a class in quantum physics in order to enhance my trivial knowledge of quantum mechanics.double-slit-electrons

Another idea that intrigued me was the table that when touched projected out particles, and could be manipulated and create waves and patterns.  Before camp I had an idea to build a LED table with my friend.  This table would react to objects touching the table, or even shadows passing by.  LED’s would light up and flicker out like a wave when a pebble is dropped in a pond.  They slowly flash and ripple until they die out.  Another cool aspect of the table we were trying to build is that it could flash different colors to music playing in the room.  Now I am intrigued to use multitouch from the design shown to us today to improve my idea.data_item_1_imgtable

Today, I witnessed one of the coolest things ever. No, I’m not talking about Harry Potter- that’s tomorrow-, but what I did see was ferrofluids in action.

spikes Ferrofluid is a liquid that becomes polarized in the presence of a magnet or a magnetic field. When it is magnetized, it will usually become cone-like prongs that shoot up from the surface of the liquid. Since a person can magnetize ferrofluid and make it stick up, it is known as a “liquid metal”. You can make ferrofluid by mixing iron dichloride, iron trichloride, and ammonium hydroxide. After that, we had to drain the water from the solution three times. From there, we used the magnet to make the spikesspikes propel from the liquid surface. However, there is a large problem with ferrofluids, which is making the actual liquid. Making ferrofluid is like baking a cake or something; it takes patience and precision. If one screws up with measurements or mixes the chemicals together slowly, then the fluid will not stick up, which occurred to my group today, unfortunately. But it doesn’t matter because I got to see everyone’s ferrofluid. The ferrofluid lab today reminded me of what a counselor told us earlier this week. The counselor told us that nanoparticles have certain properties that are unexplainable and incomprehensible. Some would say that these properties seem to break the laws of physics.

This lab not only showed us science but also revealed a artistic aspect. Many museums and art exhibits use ferrofluids to entertain the audience. Also, some artists, like Sachiko Kodama, utilize ferrofluids for their art forms. kodama

Day Five- 7/13/09

The lecture given by Rita and Gao this morning was centered around shape, in nature, in engineering, and in art. One random thing that I thought was cool during the lecture was learning that opals are clusters of nanospheres that reflect light and that their colors are resultant from shape differences, because I was always fascinated by opals when I was younger. I also thought that the video on the fabric of space-time was interesting, but a hard concept to truly grasp. Einstein said that space-time does have a shape, which curves and warps, and this curvature causes gravity. I looked it up to try to understand it and gravity better, and this article is easy to comprehend but I still have questions about how black holes fit into this model and about what it is composed of-although, so do scientists much more brilliant than me. The relation of structure to function, as it relates to living things from cells to entire organisms, was a theme I had been made very aware of last year in AP biology, but it can also be applied to manmade structures, and we can get inspiration from nature.

The Aboriginal art in the “Icons of the Desert” exhibit at the Fowler Museum was really beautiful; I especially liked the more abstract pieces. I thought it was interesting how the elders, upon realizing that their sacred works revealed too much, changed their style to be more abstract.

art of the desert

It was sad to hear that the indigenous peoples of Australia were treated in much the same, terrible way that the indigenous peoples of the Americas were treated. I wonder why almost all the paintings are composed of a great number of dots; I wonder what the significance of that is and what tool was used to paint. It made me think of when pointilism (images composed of dots) was part of a lecture. Dots are used in print and screen, and it different art movements from different cultures, such as neo-impressionism, and that artist Yayoi Kusamo who is obsessed with dots.

Visiting the  UCLA Plasma Research Center was a really cool opportunity; the machines were huge! dscn1764I was amazed at how people could hand construct all that; it seems so complicated. I was glad to clear up what exactly plasma, the fourth state of matter, is (how it becomes plasma when the electrons separate and atoms can no longer form at such intense heat), and what is is used for (which is a lot of things: electronics, as a semiconductor, possibly for energy through fusion in the future). I was kind of surprised to hear that our sun has a very cool temperature for plasma, and that it’s massive energy is only resultant from it’s size-a small amount couldn’t power anything.

The special collections was neat too; I thought it was really cool to see all the old books and other publications that we’ve learned about the impact of and read excerpts from in school, such as Copernicus’s De revolutionibus orbium coelestium from 1543, a first edition of Darwin’s On the Origin of Species, the letter from Florence Nightingale, and to see  how old medical journals and ways of drawing anatomy-it’s funny how in medical drawings the body was depicted in classical poses with a background. Obviously things have changed but I think it’s cool that doctors and scientists still today can research from the rich collection and vast sources of knowledge spanning hundreds of years to support scientist progress today through rediscovery.

The Ferrofluid lab today was very interesting. The process of making the ferrofluid took a lot of patience, but was worth it once it was complete and we got to see how it moved and changed due to the magnet. My group’s ferrofluid did not turn out quite like the other groups; it moved with the magnet but did not form spikes.

Thinking back on it I think we might have rushed the step where it sits on the magnet until the water goes to the top and begins to become clear. dscn0154I think that if we let it separate longer we might have had better results. Observing the ferrofluid made me wonder what kind of things this technology is used for today and what it could lead to in the future. Because of its relation to magnetic one day it might be a common material or used in equipment.

 

 

I also enjoyed the lithography lab today. Lithography is a method of printing something in stone or other material, for example today we used copper. After lab I decided to find out more of how it works. It uses a fat or oil to divide the surface of the material into hydrophobic areas. I remembered the word hydrophobic from the visit to the Dunn lab where we saw and learned how about hydrophobic and hydrophilic materials. Things that are hydrophobic repel water. The hydrophobic areas of the copper keep the ink in while the hydrophilic areas reject it making the background. dscn0168
