FINAL YEAR PROJECT PRESENTATION

Overview

Lessons Learnt

The Precursor To It All

Sequence of Events

Pluronic F127 instead of BSA

Chemistry is not just mix-mix-swirl-swirl

Some... Technical Details

Learn the synthesis procedure

Nanoparticles CAN be synthesised with small radii

Learning Outcomes

Spectral Analysis - Trend and Calibration Curves

Successful experiment: the cumulation of engineering foundations

Time management, planning, strategising

Success or Not?

Project Introduction

Time Taken: One Run

Caculation of amounts to react: 5 minutes

... and WHICH papers to review

The need for literature reviews

Preparation of reagents for desolvation: 30 minutes

The objective of the project is to...

???

Desolvation: 20 minutes per sample

But first, laboratory safety and synthesis procedure

Cleaning up + storing samples: 20 minutes

Spectral Analysis: 5 minutes per sample per analyser

Plotting of Curves + Data Analysis: 30 minutes+++

Total for 5 samples: 235 minutes = 4 hours

To Make It Better...

Further minimise the nanoparticle size

... How?

That's A Wrap

Experiment Design: What most affects particle size?

Is it feasible? How can I justify?

Questions?

Will it... work?

The Improvement: Round 3

Pictures

Revisiting the Lab

Many difficulties in carrying out the experiment

Finally, things are working out!

Time is short, not able to carry out all experiments

Haywire results because of...

Particle Size Analyzer shows smaller sized NPs. Success!

The Stock Solutions: A Story of Massive, Massive Error

Assumptions undermined, recheck again and again

The Improvement: Round 2

Lessons Learnt II

Literature Review: What other researchers did

Error minimisation in ALL experiments

Recalculated, remade, rechecked, reconfirmed

Problem: Lab does not have equipment. So, improvise

Research: Learning from unknowns, finding answers to unknowns, encountering new unknowns

Delays, more improvisation, more errors

Time is never on my side

The mindset to independently carry out experiments, to learn from failure, and to be creative and innovative

Success in learning something new
