Nanoscience personal statement example

Why do you want to study this course or subject?

What draws me to nanoscience is that a material's behaviour can be changed without changing what it is made of. In Chemistry we learned that gold is unreactive and yellow, yet a suspension of gold nanoparticles can be deep red and can catalyse reactions on its surface. The explanation involves surface area to volume ratio, quantum confinement and how electrons in small particles interact with light, and I found that the more carefully I read about it, the more the standard categories I had been taught began to blur. Structure at the nanometre scale sits between the molecular chemistry I enjoy and the bulk properties I meet in Physics, and I want to study the subject where those two descriptions have to be reconciled rather than kept in separate exercise books. I am also interested in how much of the field depends on measurement. Reading about scanning tunnelling and atomic force microscopy made me realise that an image of a surface is a reconstruction built from a signal, not a photograph, and that understanding the instrument is part of understanding the result. That appeals to me because I like knowing why a number can be trusted. Beyond the science, I am curious about the practical questions: whether nanostructured coatings and catalysts can reduce the amount of scarce metal a device needs, and how the toxicity of engineered particles is assessed before they reach consumer products. A degree covering synthesis, characterisation and the physics of small systems, with laboratory work throughout, is what I want. In the longer term I would like to work in materials development, probably in industry, and I expect a nanoscience course to give me both the theory and the instrument literacy that requires.

How have your qualifications and studies helped you to prepare?

My A levels in Chemistry, Physics and Mathematics have given me most of the foundations I expect to build on. In Chemistry I have enjoyed physical topics most, particularly kinetics and the way surface catalysis reduces activation energy, and I am comfortable with practical work including titrations, calorimetry and preparing and recrystallising an organic solid. Physics has been useful for a different reason: electric fields, potentials and the beginnings of quantum behaviour, including the photoelectric effect and wave-particle duality, give me the vocabulary for reading about confinement effects rather than just accepting the phrase. Mathematics supports both, and I have found differentiation and exponential functions turning up constantly in rate equations and decay processes, which has made the algebra feel less abstract. For my EPQ I investigated colloidal silver, looking at how it is prepared, why particle size affects its antibacterial action and how far claims made for it in health products are supported. Researching it taught me to read primary literature slowly and to distinguish a review article from a manufacturer's summary. I also learned to be honest about the limits of my own sources; some of what I found online about nanoparticle safety was not traceable to anything I could check, so I left it out and said why. I write up practicals with attention to uncertainty, which my Chemistry teacher encouraged after I initially quoted results to more figures than my balance justified. Outside the specification I have been reading about nanomaterials in energy storage and following news coverage of battery electrode research, which has shown me how far apart a laboratory result and a manufacturable product can be.

What else have you done to prepare outside of education, and why are these experiences useful?

At home I grow crystals, which began as a way of using up chemistry from a school kit and became a sustained interest. I have grown copper sulfate and alum crystals and kept a notebook recording cooling rate, seed preparation and the clarity of the result, and I can now reliably produce single crystals rather than a mass of small ones by cooling a saturated solution slowly in an insulated box. I have also tried making a simple gelatin-based colloid and observing the Tyndall effect with a laser pointer, which is a modest experiment but gave me a feel for how scattering depends on particle size. Working alone like this has taught me patience and the value of changing one variable at a time. At college I volunteered with three others to run a hands-on station at a science morning for visiting Year 7 pupils. My part was the non-Newtonian fluid demonstration, and I was responsible for preparing the mixtures, explaining what was happening and keeping the table usable between groups. The challenge was pitching the explanation: my first attempt involved the word viscosity and lost everyone, so I switched to asking the pupils to compare pushing slowly and hitting quickly, then named the idea afterwards. Coordinating timings with the other stations taught me to be flexible when a group ran over. On Saturdays I work at a garden centre, mostly on the tills and restocking, which has made me quicker at dealing with customers who want advice I am not sure of; I have learned to check rather than guess. I also play badminton in a local league, which gets me away from a desk and has taught me to keep going through a run of losses.
