and the emergency vehicles are still there. they also have the whole building cordoned off. great! there goes my productive work for the day. sigh. i have a seminar to attend in an hour and then it’s home. i have to finish reading the first two chapters of Molecular Symmetry and Group Theory which talks about the symmetry elements in point group theory. If you couldn’t figure out already, this is a part of advanced inorganic chemistry. And of course, I also have to do GRE prep.

Well, my mentor and I were almost to the point that we could start the laser ablation (PLD) and then we smelt something nasty. And we looked around to locate the origin of the odor and then we hear sirens. We then got out of the lab to see lights flashing and the people getting out. And as we went down the stairs, we noticed that the first floor was full of smoke. And then within 2 mins, the ORNL fire department and emergency vehicles pulled up. That was quick response! After we got out, we asked around to see anyone knew what the smoke was from. Once the firemen got out with a black burnt hunk of metal, we realize that it was a smoking tube furnace. I’m told that we might not be able to operate any tube furnaces for a while. That’s a kink in our productivity because I still need to anneal substrates and don’t want any setbacks. My mentor told me that Los Alamos had a bad laser accident and they shut down all the lasers in the lab for two months. That must have really slowed their scientific research down because a lot of science research is done by lasers. They are trying to figure out if the smoke was toxic or not. I guess we will be told soon enough. I’ve been told that safety is a serious issue at ORNL and it should be. Our division now has a ton of paper work to fill out about this and has deal with possible repercussions..

Lets see what happens now. We need to get back into the lab to finish my thin film growth.

i was threatened with bodily harm for logging onto someone’s computer. i don’t think i did anything wrong except for etiquette. i shouldn’t have used his computer but it was right there and i was getting bored while substrates were being cut. he said that if i ever did it again, he would break my fingers. geez, that’s one abrasive guy. he is a huge hulk looking piece of meat. i know ORNL has strict rules against physical harm but I don’t know if this is worth reporting. i know i’m never logging onto his computer anymore. but if i did, which i won’t, i would log on and then remove my user id upon restart. i think putting in his user id and then putting a wrong password resets the user id field back to his. my mentor apologized to me for his rudeness. oh well, that’s some excitement for today.

i’m in a weird productive mood today. i have to cut more substrates and then clean them. i also need to etch and anneal them. i have a lot to do this week.

i had a lot of fun at the balloon festival on friday evening. and the country concert was decent too. i am going to put up pictures soon.

i got caught up with everything going on at school because i got to talk to britta, kelly and goms. i chatted with andi for a bit and i’m going to call her tonight and talk to her. i haven’t talked to andi for a week now because i’ve been soo busy.. sounds like she had a cracker of a weekend. i’m jealous.

I think someone actually is reading my blog. I am amused because I know where the reader is from. Oh well, another spectator for the ride. I wonder how long they are going to be with us.. They must have tagged my blogs to check for updates. This is cool! I wonder if I will get any comments.

And I did an AFM run of LaAlO3 and didn’t realize that it was supposed to be rough and thereby I wouldn’t get any fine features. I sat there for 30 mins trying to figure out why I couldn’t see the terrace features. And then I looked at the sample and thought that the surface was pretty rough as I could see features with my eyes. So essentially after talking to my mentor, I found out that I got exactly what I needed. I just have to increase the z scale to see more macroscopic features. And that also explained the reduced amplitude setpoint. There is so much to learn about the AFM and I have just stratched the surface. I have quite a few samples to do Monday morning.

Lab Notes: Research from the Berkeley College of Engineering

This is a short article on Berkeley’s new optical microscope that has a resolution of 60 nm which is amazing. Yeah, the AFM has a resolution of a few nano meter but this is an actual image. This is very promising!

I’ve been thinking about my exprerience here so far. I am amazed to see how quickly time is flying by. Getting up for work around 6.45-7 am everyday, then 8 hours of research at the lab except when I have the tuesday thursday Advanced Inorganic Chemistry for an hour and a half in the morning, and the mandatory Wednesday afternoon seminar on various scientific topics. So usually have long days and then workout in the evening for an hour. I can’t really do much here except for running and pushups and crunches and stuff. I get pretty tired after running for 20 mins. Must be the altitude and the speed I try to sustain. I guess I’m spoilt running on the treadmill at Coe which keeps me in check.

About the progress in research so far. I guess I have made a few Bi based oxide thin films using PLD. Apart from that I’ve learnt how to use the tapping mode in the AFM. The AFM i’m using is very similar to the one we have at Coe Physics except, Coe’s is newer. And the images I’ve scanned have had a 50-50 clarity consistency. Must be the tip. I keep thinking that I’ve broken the tip by getting it too close to the surface. Ho Nyung, my mentor thinks that after scanning a hundred samples, I’ll become an expert. Probably true. I think he is moulding my project differently that what he had planned earlier. He says that he plans for me to use the AFM a lot. I haven’t done any X-ray diffraction yet.

And I talked to Andi at the perfect time on Sunday. I wanted to talk to someone about something I had learned about myself from Jenn. Andi just listened and it made it feel better. It was about how I can be demanding sometimes especially when it came to food. Jenn and James cook every time and I can’t really help because I have nothing constructive to help with the process except cutting veggies and dishes. And our kitchen is soo small, it can barely hold two people in it. And the way, I phrase my requests that sounds like commands and not requests to people here. I guess that is true because we have not known each other for long enough to get comfortable enough to rid formalities. I went into the mode that I am with friends from school like Britta and Andi and such. So, I just have to careful how I say things now. I guess it will be little hard to pay attention to everything but it will work out. I like the fact that Jenn told me because I would have been oblivious to this and would have continued my lack of courteousness in my interactions. It not like I am not courteous, I just don’t say please all the time.. Just one thing, people here don’t really communicate as to how they feel to the person they need to talk to the most. Except for Jenn. I’m glad for her honesty with me. People are having serious room mate issues and are bitching about it to other people but when suggested to talk to their roomie, they shrug and say they don’t want to confront the situation. I know that people aren’t very observant of change in behavior, and they will never know unless they are told. I hope the girls figure out and solve their issues. On the other hand, so far James and I are doing great. He is a good friend and room mate.

I got wonderful news from Britta. She is going to be around for my final semester because she is not doing her study abroad in Sweden. It makes me soo happy. I miss her a lot. One of the very few people I had to see everyday. She will be there for my graduation.

Bonjourno from Italia! We got here 4 days back and it’s been a blast since then. Fantastic food, magnificient sights and sounds and Venice! I don’t have much time now but I’ll write in detail when i get more time on the computer.. hopefully that’s soon! i have a ton of pics to put up when i get back. Borate Conference 2005 in Trento, Italy starts today with the reception tonight.. time for the work to begin..

it’s good to be connected to the web again! damn, i’m addicted. my one addiction!

I spent the last month and a half writing up this article that needs to get published and a poster presentation for Trento. This is the final product after lots and lots of editing!

My article titled “A solution approach to high alkali content borate glasses” and my poster presentation with the same title which is a summary of the paper with prettier graphs..
