Fall leaves? Quilt? Not quite...

Cornell researchers have turned science into art as they explore the shape and size of atoms along grain boundaries in graphene,  a University press release said this week. David Muller, Professor of Applied and Engineering Physics and co-Director of the Kavli Institute at Cornell for Nanoscale Science, lead a group of researchers that examined the microstructural properties of the two-dimensional form of carbon known as graphene in order to better understand its electrical and magnetic capabilities.

They found that the graphene grows in imperfect sheeets, where the hexagonal lattices do not align in perfect order. The scientists then observed the intersection of these lattices by bouncing electrons off the atoms and color-coding the different diffraction angles. What resulted was a pretty collage of colors resembling a patchwork quilt, seen to the right. The method used to display the varying orientation of the grain boundaries could potentially be used for many other one-atom thick layers of materials.

“You don’t want to look at the whole quilt by counting each thread. You want to stand back and see what it looks like on the bed. And so we developed a method that filters out the crystal information in a way that you don’t have to count every atom,” said Muller in the press release.

While conventional materials science supposes that a high number of grain boundaries would inhibit electrical conductivity, which occurs via the movement of electrons within the material, Muller’s team found that larger grain sizes and fewer boundaries didn’t necessarily mean higher conductivity. Instead, poorer conductivity is believed to be more a result of non-unifom atoms or particles that reside in the material due to manufacturing processes. With impurities as the culprit, scientists can now focus on ways to improve the graphene-forming process.

Graphene is a very commonly used one-atom thick layer of carbon, implemented in the design of solar cells, cell phone screens, and other devices. Mike Ramsey of The Wall Street Journal explored the future of energy-efficient cars yesterday, discussing the possibility of ultracapacitors replacing batteries as power sources. Ultracapacitors quickly absorb and discharge electrical energy by use of two carbon-coated conducting plates suspended in an electrolyte solution. The carbon-coating he speaks of? Graphene.

Here is a list of interesting facets of the Engineering School / lifestyle that neophyte freshman will find useful.  My close friends may identify me as not being the ideal student to provide engineering insight, but here i would beg to differ (I never said anything about facts regarding being a good engineer).

It’s OK to suck: You’ll hear it over and over again your freshman year, but that doesn’t mean it’s cliche.  In fact, the required engineering 1050 seminars are basically all about this; A+ students in high school and overachievers are going to at one point or another get their buttocks handed to them in a tightly bound, light blue, test booklet.  How you handle this is entirely up to you.  As you ascend into higher level courses, increasingly more weight will be added to the final exam score – until then, nearly all classes have multiple tests and projects to keep your grade afloat.  Professors have become very accommodating to try and deflate the image of an overly grueling curriculum.

Students are cool with cheating: OK, maybe not exactly cheating.  But I remember as a senior high school I heard rumors of how engineers would refuse to share their homework or provide extra assistance to a classmate in need.  While certainly there are students here and there who won’t be inclined to work as a team on an assignment, these usually aren’t the people you choose to pair up with.  The competition is certainly present but you’ll never be hard-pressed to find engineers fervently copying each other’s homework before a deadline.  While cheating doesn’t run rampant by any means, you’ll occasionally hear of someone trying to submit false re-grades.

Duffield = Disneyland: You’ll never have to leave Cornell’s engineering hub.  The biggest building on the engineering quad is a smorgasbord of food, computers, lounging, all the people you know (and compete against), and temporary overnight beds (chairs).  As an engineer, you’ll spend most of your time and around Duffield Hall.  A few highlights: 1) open 24-7, good luck on Saturday, 2) coffee dispenser downstairs in Upson, connected to Duff; it’ll come in handy, 3) tables upstairs overlooking Tower Rd. provide some of the best people-watching on campus, and 4) all Collegetown restaurants know The Duff and love to deliver there.

Professors / TAs: You’re likely to read about self-absorbed professors and incompetent TAs before coming to Cornell.  However, in my two years here, I have found that this problem is largely overstated.  While some classes are taught by professors consumed in their own research, and everyone has a TA horror story, my experience has been quite contrary to this.  Even if your TA is one of the less qualified ones (and some are undoubtedly better than others), there are numerous study sessions and separate office hours that are all accessible by anyone.

Study Corner: Most of an engineer’s time is spent studying – seriously.  Here’s some of the lesser-known places to look out for: 1) Phillips Hall, accessible 24-7 through Duffield.  There are numerous, huge open rooms with projectors and chalkboards.  2) Random Lounges – there are comfortable and homey rooms scattered all over the engineering buildings.  There’s an MSE lounge overlooking Cascadilla creek, a reading room in Snee Hall, and lounges in 3rd floor Thurston, for starters.  3) Carpenter basements.  It’s impossible to NOT get work done when you’re buried deep within the bowels (ew?) of Carpenter Library’s stacks.  You don’t even have to crack a book open, it’s almost like you just absorb information.  It’s very isolated, somewhat dark, and there’s even a huge empty room with desks on the bottom floor in the corner.

Always keeping you abreast of the technology advancements in the Cayuga Community, engineering correspondent Renick is here to bring you some fascinating news.  The latest developments by Cornell geeks have been profiled in an article here.  On a budget of $75, Cornell students created at least three microcontroller projects, including an airship and an automated guitar hero player.  Sweet.
