Howlers of the week 2007/8
These are all genuine sentences and paragraphs that were written by students in their write-ups for the 2nd year practicals, or library projects, or in
exams. Remember that spelling mistakes, grammatical errors, and errors of logic are all entirely theirs, and have been reproduced exactly as they
appeared on the student's script.
2nd year Teaching Lab experiment on Colloids (formal write-up)
- The rate for this run is unusual slow, this is presumed to be an error in the results, probably because the switch that starts the recording of the
data was not switched.
- A colloid is a mixture of two different phases, a dispersed phase made of particles of larger particles.
- For the Na2SO4 there is no correlation in the data, this is what you would expect because of the poor data collected in the first part of the experiment.
- Proteins are also polymers but they are just natural occurring polymers.
- The tea contains tannis in it.
- A cup of black tea was made, ensuring that the tea did not turn into stew.
- Due to undefinable errors their experiment didn't succeed.
- The two solutions were added to a vial, shuck, and left to stand for 5 mins. In the next experiment, egg white was added, shock, and left to stand.
- KFAST is the rate of the reaction above the c.c.c., so the rate of the highest concentration has been used, as this should defiantly be above that.
- This is the point of the plot at which the curve flatteners off.
- This is a PVC is a stabiliser of the colloid, is does this by coating the colloid particles.
- This same solution was then spilt into two...
- The IPA denatures the protein, and stops it being a big particle.
- These results confirm agree with the theory and are what I expected to receive.
- The short-range repulsive forces and the long-range Van der Waals’ forces can be bought together and expressed by the Leonard Jones potential.
- Unfortunately the results could not be analysed due to all the data being incorrect.
- The colloids was Fe(OH)3 particles suspended in solution.
- The attractive forces the colloid particles are van der waals attractive forces and between particles.
- Half of this solution was heated to 60°C and left.
- Egg white contains protein which when mixed with alcohol or the tannins found in tea causes them to shrivel up away from the colloids making them unstable.
- In order to investigate the c.c.c value more then more kinetic rums could have been made
- When water is added, the colloidal particles sink and don't really do very much. When PVA is used, the colloid particles just hang there throughout the solution.
- When you depress the plunger, the colloid solution shoots through the system.
- I found that in my data there were significant errors and anomalies which include the second graph which should be the inverse parabola that it is.
- Adding PVA works by the addition of strands to the colloid surfaces that form a kind of net.
Water is shown below. In isopropyl alcohol.
- Emission spectra is the spectra of energies that atoms "spit out" to regain stability.
- Diamond is a cauliflower, but sometimes it has a smoothness.
- C2 swans were the dominant feature of the spectrums.
- I wish him the best of luck in his fourth coming thesis.
- The radicalised carbon that is left after a H abstaction reaction is called a 'dangle site'.
- The optical microscope analysis of the film is observed to be of a "scratchy nature".
- These results can be seen in my appendix.
- A diamond surface can be modified by attaching a molecule to it via an ironical bond.
- XRF is when a high energy electron beam is fried at a surface.
- XRF and AES are similar but different.
- The molecule can firstly adsorb to the surface, and then worry about breaking its bond.
- In physisorption the energy is not enough to brake a bond.
- In AFM, the tip is dragged across the surface and bumbles over particles.
- At 0 K, the disorder that remains in a crystal is called 'frozen entropy'.
- This furan synthesis is called the 'Foust-Biriani' reaction. [Ed: Should be Feist-Benary]
