This slide follows the traditional slide design, which Professor Schreiber used until learning the sentence-assertion design. The reference [Kesler, 1994] gives credit to the illustration on that slide. For a discussion, see the reference below.

Comparative Analysis of Pb2+,Cr3+, and Cd2+ Content and Inference of the Sources of Such Ions in the Pasig River During Rainy and Dry seasonsMention what happens not what you will do in your methodology.A list bores the audience! No need to mention amounts, unless crucial.18From Schubert, U., et.al, Materials Syntheses: A Practical Guide. New York: Springer Wien 18AuCl4NaBH4AuAuAuAu++++++Au+++++++AuNPs are synthesized from AuCl4- and are stabilized by CTAB19CTABSo we start with the seed crystal. A solution of 0.0005M AuCl4. 0.01M NaBH4 was added to reduce AuCl4 to metallic Au. There are Cl- in the soln too but let us just focus on one AuNP. 0.2M CTAB (cetrytrimethylammonium bromide) was added to prevent aggregation (lest, lose its quantum properties). This was done by providing a charged core shell so individual NP repel from each other.19Keep explanations brief.Use pictures rather than long stretches of sentencesTables instead of listing dataPRACTICE your spiel! (avoid unnecessary words and/or repetitions)Varying the aspect ratio varies the max of the spectra.

Guide the audience when you explain complicated pictures/graphs.Thats why youre given a laser pointerOrganize the way you introduce the picture/graph

Soc., 2006, 128 (6), 2115-2120.The diagram shows a light-field image under an optical microscope. The circle signifies the laser spots in the sample. The sample was stained with Trypan Blue, an organic dye which detects dead cells by giving off a blue color. Therefore, we can see that for the malignant cells, the cell dies even with a laser power of 80mW. This is compared agains the nonmalignant cells which starts getting injured at 120mW. This, then, proves that photothermal therapy can be selective to cancer cells.2330:70 (v/v) EtOH/H2O50:50 (v/v) EtOH/H2O70:30 (v/v) EtOH/H2O280nm2.02.93.1475nm1.42.02.4520nm0.30.60.6800nm0.50.80.9Absorbances at various wavelengths were obtained after immersing the complex in different solvent systems.Use pictures for enumerating examplesA list is okay but a list of pictures is better. Different types of interaction allows for bioconjugation

26Avoid text-heavy slides. If inevitable, do not flash them at once.7x7 rule(for the body): 7 words, 7 lines per slide ONLY. Use SIMPLE animations. My personal favorite is appear and wipe.SUMMARYParticles exhibit quantum-size effects when reduced to nanosize which is not present in bulk molecules.Using AuNRs with appropriate aspect ratios, one can couple cancer detection with selective killing of cancer cellsEven labels in the pictures are distracting when they are too many.

Your body posture and gestures can affect the way you deliver a talk.Dont be a distraction to your own talk!Voice projectionBe conscious of your uhmms and aaahs and like.Keep within the time allowed. Practice and time yourself!Estimate the length of your talk. Time management is 5 points of the talk. Most profs give you 0 if you go beyond the time.TECH STUFF: Include an outline at the start of your talk.It gives the audience a sense of the big picture.

BeforeThe Core of This TalkScientists are on the move from programming complied languages (Fortran, C/C++) to environments like MatlabWhy? Matlab is easier to use and feels more productiveWe can extend Matlab way of working far beyond Matlab.35Traditional mapping slide. No assertion exists of this slide to put the contents of the presentation into perspective. Also, no images exist on the slide to help make the contents memorable.

TECH STUFF: Include slide page #. Begin and end with the title slide.Teachers need to know who you are! (and sometimes they come in late. :P)Slide page # is for reference (for questions/notes)

TECH STUFF: Always put references. DO NOT PLAGIARIZE.Font size: ~18Pictures, graphs, tables must have references when they appear in the slide.Summarize all references at the end.TEM image of AuNR shows uniform aspect ratios.39Daniel, M.; Astruc, D.
