engineering school

according to my good friend Hannah, engineers become engineers to escape writing lots of papers.

apparently, this is not true in my program this quarter. I'm sitting here, in the Suzzallo library, staring down three intense reports that have to be done before the end of the quarter.

Thanks to the SPU/liberal arts/UScholars, I don't mind writing, but I'm not enjoying this paper. I am digging through literature that is older than my grandparents and reading 'reports' that really should be books. (I mean, when has anyone published a 86 page literature paper??!)

I did come across this gem in a footnote about the marcasite form of FeS2:

"I  was prepared  to  have  quantitative  analyses made,  but  our  best professional
analysts  (including  Miss  Mary  G.  Keyes  and  the  new laboratory  for  rock  ahalyses
in  charge  of  Dr.  Grout  of  the  University  of  Minnesota)  declined  to  make  them,
pleading  inadequate  equipment  for  sulfide  analyses. Where  can one obtain  reliable
sulfide analyses? My  own  experience with  the  routine  commercial  analyst  is that  he
cannot  be  relied  upon  for  scientific  work."

I'm also enjoying the fact that this paper is all about politely telling the world that the previous analysis of marcasite by Huggins is wrong and he just got lucky that his mis-labeled axes (is it bad that I had to look up the plural of 'axis'?) actually kind of worked.....

back to the paper.

(somedays I'm thankful we don't see sun everyday in Seattle. too bad today is not one of those days.)

I wish I was an Astronaut

just to see this:

what an incredible view. 

It's easy for me to forget the big picture when I've been in my windowless office for days, but then I find something like this video. wow. did you see the Aurora Borealis?? and the lighting storms?? Even though I live in a big city, one of millions of people, the night images of the Earth, with all the bright city spots, reminds me just how big the world actually is - almost 7 billion people! And then I  remember how small our little blue planet actually is in the grand scheme of the universe.

anyways. the likelihood of actually seeing the earth from space is slim, either on the ISS or on another space-bound mission. I'd be content to see the Aurora Borealis - it's going on my list of things to do when I spend a summer researching in Sweden!

oh. apparently NASA is opening Astronaut applications today......

watch the announcement.

(I met one of the astronauts up there! so good to see him still in the program!)

(and the woman speaking about the hiring process, Dr. Janet Kavandi, graduated from the UW!)

awkward

This morning, I almost had a super awkward experience with one the guy who sits in the desk next me. Instead it was only kind of awkward:

It was before 10am, and as usual, I was the only one in the office. I was really really really tired this morning. My cup of tea got me through the 7:30am bus ride, hour prep for my meeting with my advisor, and finally through said meeting, but I was fading fast post-meeting. So, I figured since I'd be the only one in the office for a bit, I curled up on my chair, which is decently wide, and closed my eyes for ~6 minutes.

unfortunately, my legs like to fall asleep quickly when curled up, and so I decided to move to nap under my desk for 10 minutes.

I only needed a 10 minute power nap.

So, here I was, crawling under my desk, which is decently spacious, and just settling into my nap when I hear the lock turning in my office door.

uh oh. apparently my office-mate decided to show up to school this morning.....
(this is guy who thus far has only ever said "Oh! I didn't know you were that tall!" to me a few weeks ago - he hasn't been in the office very frequently lately)

as quickly and gracefully as I could, I reached for my computer power cord and pretended that I had to be on my hands and knees, completely under my desk, to get it plugged in. Fortunately for me me, the plugins are inconveniently located under my desk in the far corner....but it was already plugged in.....so I pretended that I had just finished plugging it in....

second sentence he ever said to me: "Are you alright?"
"yep, yep" just plugging in my laptop"
third sentence: "there's a strip cord over here you can use if you want."
"it's okay, I've got it figured out, thanks!"
(besides - who knows when I might need that excuse again?)

I crawled out from under my desk and started working again. no nap today.

I'm 99% sure he bought my story.

-----------

tomorrow's a day 'off', but I find this quite appropriate:

you know I'm going to be in tomorrow by 8:30am. 

blessed.

I'm currently sitting in what is probably a multi-million dollar house in Queen Anne that has the most breathtaking view of Seattle I've ever seen. With a view similar to that of Kerry Park, the house is designed with 3 stories of windows that face out towards the water, so whenever you look outwards - there sits Seattle. I just can't get over how incredible the city looks at night.

{this is legitimately what the view looks like, only everything appears even closer and larger....}

tonight, I was supposed to edit NSF fellowship essays, but instead I've been sitting in a tastefully designed house drinking tea from an Olivia the Pig mug and enjoying being in the same room as my roommates. not gonna lie - this house is a beautiful combination of everything I've dreamed about in a house - open, spacious, lots of windows + natural lighting, decidedly minimalist, but still incorporating lots of floor-to-celling bookshelves full of english, art, design, and scientific literature.

we read love poems from a slim red volume, started a game of scrabble (but only got as far as 'daft', thanks Steph :) ), played with a soft hamster, and I finished editing some photos of my newest skirt.

all in all a good evening. so blessed to live in this city, to live with these women, to be pursuing a research degree in a field that I love, and as I was reminded last night while reading through Colossians 1, I'm so blessed to be a part of the Kingdom of Christ, forgiven and redeemed.

cômmuter

midterms = no posts for a while.
midterm over = posting again :)
(if you want to know, midterm did not go as well as I would have liked. 1/10 of the points were on a topic I've never studied before, there was no homework covering it and we only spent 10 minutes and one slide on in class on it. we covered 150+ slides.)

my roommate's feelings about my mysterious disappearance into homework/study mode this past week:

you'd think they'd remember being a student! It has only been 5 months!


*warning - this blog post gets a bit nerdier than the past ones*

mainly because I've been charting my average cycling speeds to and from school each day!

see?! my average is increasing! Okay, it's barely increasing, but it's something! Also I find it interesting that the slopes seem to parallel....that probably means that if I factored out the extra speed I get coming down the massive hill right outside my house, I would get roughly equal average speeds each way. hmm.

Buying my new bike was probably the best decision I made about bike commuting - it may still be tough to wake up and get out of the house before the sun rises every morning, but then I get on my bike and remember why I signed up for this :) The hill home is still not fun, but I make it up consistently now. And as pictured in the picture below - I'm getting better at tweaking my bike. I added the back rack all by myself! (Well, I also put on the waterbottle holders and bike lights, but those are easy. Taking apart the brake and pin from the wheel - a bit more tricky for me!)

Second best decision - getting a bike locker. No one knows my bike is locked in it and it stays dry! (well, the asphalt sometimes gets wet from creeping water, but my actual bike stays dry) So, I can bike to school, and if I am too tired, too sore or it gets too late, I can grab a bus home and not worry about my bike. Best ever.

And all the time I spent researching for an excellent pannier has paid off. (I spent close to 2 weeks searching the internet) Mainly, most of the waterproof backpacks and panniers are not very attractive. I don't know who decided that waterproof = poor color choice and only square shaped bags with strangely placed straps, but Knog did not listen to them.   I love love love my Knog Dry Dog pannier!!

(sorry if you don't care about my pannier, but I'm going to write a baby review here because I could only find one online and I think it deserves way more!)

Firstly - the 17" bag is HUGE. Like, super-duper large. I lose things all the time to the bottom of the bag and half the time I stick my head in the bag to find something. It's like a giant black hole. or Mary Poppin's carpet bag - but better, because it's absolutely WATERPROOF.

(it's about as big as my torso!)

The way the Dry Dog closes is one of the best techniques I found online. It may be similar to the Ortlib bag, but not really from what I can tell. Here you roll the top down and then bring the clips together in the middle, which really keeps the water out (and air in if you're not careful!) but then the over-the-top flap is shaped to get envelope the whole opening, doubling the waterproof-security. And it clips down, unlike the ortlib one I was looking at, which used velcro. I love velcro, but I have more faith in clips/snaps. I recently rode through a decent rainstorm and nothing got wet. I was soaking, but my books and computer were dry!

(twist-and-clip)

(even the front stripes are reflective!)

The pannier has a board on the backside and the Klickfix system attaches to it. It also supports your computer, which can hang out in your pannier in the built-in pocket. I still keep my computer in my sleeve when I'm not using it, just for extra protection. The built-in pocket is super padded, but conveniently keeps your laptop out of the way in your bag. And there is a mesh pocket with an elastic top halfway down the front of the computer pocket, which is a great place for keys, headphones, wallet, etc. Otherwise the little items will get lost in the bag!

(easy, yet secure, clip on and clip off)

And, this pannier easily converts to a messenger bag, courtesy of the wide, soft and comfortable strap attached. I use this as my only bag around campus, as it still keeps the rain out when I'm walking! :) It is really easy to adjust the strap length, but if you don't have it at the right height, sometimes the back rack attachements can get caught on your pants, jacket, shirt, etc....

(strap adjustment + reflective half circles on each side!)

Overall - awesome awesome bag and it's totally worth the price and shipping costs! They have a 13" option, but I'm not sure if it comes with the Klickfix system, as they call it a 'bag', not a 'pannier'.

Now all I have to do is figure out how best to dry my bike clothing out on rainy days....I hate wet socks :)



In the meantime, this is what's on my plate for the week - thesis proposal outline + filling it all in.....

{summer interruption}

I planned to video blog through the summer, completing my final internship at NASA Ames in CA...

Take a look how many blog posts happened from June - Aug... Zero. Whoops. Apparently, I was too busy to blog, but that doesn't mean I didn't keep taking pictures and videos!

So, after about 2 months of sitting in pieces on my computer, here are highlights from the entire summer in one video! (Covering 10 weeks of fun means it's kind of a longer video and has lots of titles...)

Done. Summer adventures blogged :)

Thanks friends for a fantastic summer!

....seminars....

One part of grad school I did not expect was the number seminars I have to attend. I'm just shy of three weeks in and I've already listened to 6 seminars and have one more to go this week. (this week is unusual, mainly because my sol-gel class has morphed into guest seminars for both classes this week, so I going to 4 seminars). and last week, I went to a seminar outside of school, as I finally made it one of Seattle's Science Cafes.

This summer, I could go to just one or roughly four different seminars a week, and they usually had cookies aft wards :) I enjoy going to seminars, and as uninteresting as the titles may sound, I've found that I usually find something intriguing in each one. That doesn't always mean that I actually understand much of what is being discussed, but I try to pay close attention...promise.

Anyways, one of our seminars was actually pretty pertinent to what I am planning on researching - solar cells! This professor from the University of Illinois (who is taking a sabbatical in Oregon??) researches something called CIGS - they are a specific type of solar material that is made of Copper, Indium, Gallium, and Selenide (I think) and are becoming more promising with increased efficiencies and lower manufacturing costs. However, I am not a super big fan of the device because it still uses both CdS for an absorber layer, which is toxic (though he did say that should a house burn these panels on the roof, the vapor was not concentrated enough to be toxic) and the cells rely on indium, an element which, to the best of my knowledge, is only available in China. And I heard that recently China's been increasing prices of certain metals, and though I'm not sure if indium is one of them, I wouldn't be surprised. I think every current solar cell uses it in some form. The only major point I disagreed with his assertion that we should only focus on efficiency of the cells and that going for a cheaper, but less efficient material was a good problem for 'academia' but not really commercially feasible. Maybe it's just because that's what my thesis focuses on, and I'm a bit biased, but I think that using a cheaper, less toxic, easier to manufacture material can be a good tradeoff with a decreased efficiency. But we'll see. Ask me again in 5 years how I feel about that :)

Today's substitute sol-gel seminar was barely related to sol-gel processing (actually, I can't really figure a connection) but really interesting. It focused on a new idea for storage of energy generated from solar cells - splitting water. Since solar cells only work during the daylight hours, what happens when you need electricity at night? You can produce more electricity during the day than you use, but if you can't store it, then you lose it. One of my favorite companies, A123 Systems in MI, has developed a more efficient battery that can possibly 'stabilize the grid', basically store excess power and meter it out when needed. But this prof was discussing how if we split water into it's respective H2 and O2 components, then later on we could recombine them and get energy out when they form H2O again. Yes, you'll lose some energy to splitting the original water, but not as much as if you lost all the excess energy by not trying to store it. They are even working on developing solar cells of sorts that can sit in a clear bucket of water and just by absorbing light can power reactions that split water. To cool! Here is a sweet video he showed us, the bubbles on the front are O2 and the ones on the back are H2. There are no wires, no membranes, no nothing besides this complicated, layered metal.

Isn't it pretty?!

The other seminars - not so interesting. I may have found a new technique that will be helpful in determining charge carrier mobility (basically, how far can an electron or electron hole move in my material) but it also looks like a complicated set up :/

One seminar had lots of cool pictures because they were causing supramolecular structures to self-assemble in monolayers - randomly dispersed pieces of a puzzle come together in an ordered/patterned fashion by themselves. And they make really cool SEM pictures:

(the green overlays are the molecule outlines)

All I could think about during the lecture was how they would look really incredible blown up really large or shrunk to a small pattern and used in a dress....like these atomic bomb images were used:

(Christopher Kane's 2010 Resort Collection)

I just calculated that I'm required to go at least 90 seminars so that I can finish my degree. Oh boy.
