Last edit and changes in Femtochemistry presentation

17/1/05

Final edit put together of powerpoint, re-animating Dave's Na-I slide that was looking odd to how I know he wanted it.

Changed the wording in certain places (to help Will and Eleanor with their parts). Tried to bridge the gap, and emphasise why it was so important that Zewail won his prize.

Email explaining edit of powerpoint presentation:

sent 4/1/05

"Hey Guys,

As you can see its very late (or very early depending how you see it). Anyway I just got back to Uni today, moved in, and this evening have been working on this sodding presentation.

The amount of stuff everyone has produced is amazing, and the very rough cut came to 42 rammed slides long! A somewhat long 15 minute presentation!

I’ve been working for hours to prune it down, into what I feel may be closer to its final edited form – and working towards our remit of “WHY was Zewail awarded the nobel prize”. (I’ve done this, since no one else has got all the material and time is more than pressing on all of us and we’ve got to give this a good shot, so I hope I’ve done everyone and everything justice!)

Much has been edited down making them proper slides, instead of individual essays (had to edit a lot of my own this way too!) Obviously we’ll be reading more than what’s just on the slide – as we all will have prepared some notes beforehand, but cant really do anything until we know what slides we’ve got.

Since we have 1 working day (Wendesday) before our doomsday before Mackenzie on Thursday I suggest the following (which can be refined at a later date):

We all perform the part of the presentation we actually put together and researched, no-one will know it better! (And at such short notice that is very true).

Slides 1–5 Lucinda
Slides 6–9 Eleanor
Slides 10–17 Dave and Alice – please split up who does which bit
Slides 18–22 Tom
Slides 23- 27 Will

Also what follows is a summary of some of the more complex slides:

Slide 11 –
This is the reaction profile of a 3-step mechanism, going from products to reactants

The positions indicated in red show transition states, that are a non-isolatable species – these are at local energy maxima

The positions indicated in blue show reaction intermediates, these are isolatable species- these are at a local energy minima

The barrier with the highest energy is the activation energy

In order for a reaction to proceed the activation energy must be over come

This is some of the information gained from kinetic studies and
is one of the areas probed through the use of femtosecond lasers

Slide 12 –
First initiating probing pulse laser – excites sample and starts reaction

At a selected time interval the probing laser (that does not affect the sample, just monitors it) probes the sample – this is then detected

The secondary pulses continue giving information at pre-selected intervals (10x-15 s)

Slide 15 –
Potential energy curves showing ground state and excited state for NaI. The upper curve shows the molecule vibrations in excited NaI. When the distance between the sodium nucleus and the iodine nucleus is short the covalent bond dominates, while the ion bond dominates at a greater distance. The vibrations may be compared to those of a marble rolling back and forth in a dish. As the 6.9 Å point is passed there is a chance that the marble will roll down to the lower curve. There it may end up in the pit to the left (return to ground state) or fly out to the right (decay into sodium and iodine atoms respectively). (From Lucinda’s research – just an alternative to what you already have Dave – also replacement picture).

If for timing we have to loose slides I suggest the following be edited out:
Slides 4, 14, And a few from the further development section if necessary

We could meet after our pre-lab talk on Wednesday, (but I have to give tour guides at 12) and have a quick run through.

I really do hope this is ok – it has taken ages, please be honest in your appraisals.

Please find attached the full length, and the “Tom edit” of the presentations

Cheers

Tom

Email sent to group, regarding key skills work

"Hi Guys,

Hope you are all well and enjoying the Christmas break.

Was wondering how everyone is getting along with the Key Skills project, and how we should collate the finished sections together before we have to do our draft group presentation next week in front of Mackenzie and Hannon.

I am willing to help collate and edit the presentation together. If someone else wants to do this please say so!... Also when the editing and collating is done as a group we need to get together early next week, assign who does which sections and also have a run through to see how it fits together.

Take care

Tom"

Since then I have collated Will's work onto the end of my part of the presentation.

Meeting 2

26/11/04

General discussion, not all members present at the same time, but following points were decided upon

• Blogging essential to keeping track of resources and project
• Draft Powerpoint Presentation (of all various parts) to be ready for a meeting next Thursday at 11am, for group discussion
• Alice and Dave working together on Introduction to Femtochemistry
• Tom and Will working together on further developments of Femtochemistry
• Eleanor and Lucinda working together on the history of Zewail and the Nobel Prize
• Alternative layout of powerpoint produced and to be emailed to everyone, containing very brief draft of Tom and Will's work

Key Skills Group Work Minutes of Meeting One

18/11/04

• Blogs to be used for logging team work, so markers can see progress of work. This also means that minutes are to be taken at every meeting.


• Key to Presentation is femtochemistry and why Zwail won the prize, not the history of the nobel prize or his history – these sections should be brief but informative.


• Narrator idea to link the different sections together, could add humourous element to a "straight-laced" presenation.


• Oral parts to be re-assigned later on, since not equal in proportion in research terms.

The research and presentation was split into the following people and areas:

1. The nobel Prize – Lucinda
2. Background to Zewail and further projects of Zewail – Eleanor
3. Introduction to femtochemistry and reasons for development – Alice
4. Reasons for awarding the prize and speach – Dave
5. Further Developments in Femtochemistry – Tom
6. Research spurred by femtochemistry into cells – Will
7. Summary and Conclusion – ?

Next meeting date with research found and blogged – Friday 26th Novemeber at 12pm
