Stáž: Stabilizace zlatých nanočástic s jádrově-obalovou architekturou

Job Description

Gold nanoparticles (GNPs) exhibit plasmonic properties that enable strong light-matter interactions, making them promising candidates for photothermal catalysis. However, their optical response is highly sensitive to particle shape and therein lies a key stability challenge: GNPs begin to reshape at temperatures around 200 ??C, which progressively alters their plasmonic characteristics and degrades their performance over time. In this project, you will investigate how coating GNPs with a protective shell (e.g. titania, TiO2) can improve their thermal stability. These core-shell nanoparticles will be studied using single-particle spectroscopy: because nanoparticle shape governs the plasmon resonance, spectral shifts measured before and after laser heating directly reveal morphological changes. Photothermal heating is achieved using a wavelength-tunable picosecond laser that excites each particle at its plasmon resonance. Depending on your interests, the project may also include nanoparticle synthesis, electron microscopy correlation, or optical and thermal simulations.

Qualifications

You are currently enrolled in a Master's program in physics, chemistry, materials science, or a related field. You have a nationality of an EU-member state and/or you are a student at a university in the Netherlands. The internship has to be a mandatory part of your curriculum. We expect you to be available for at least 5 months, although longer is preferable.

Work environment

AMOLF is a part of NWO-I and initiate and performs leading fundamental research on the physics of complex forms of matter, and to create new functional materials, in partnership with academia and industry. The institute is located at Amsterdam Science Park and currently employs about 140 researchers and 80 support employees.

In the Hybrid Nanosystems group, we investigate the interaction between different components in complex hybrid nanostructures and develop new architectures for such systems.

A powerful way of designing novel materials lies in combining unique properties of separate components in a hybrid system. Nanomaterials are especially interesting for this approach as they display unique properties compared to their bulk counterparts. An intelligent combination of several material classes in one nanostructure offers a promising approach towards improving existing properties and compensating for disadvantages of the separate components, as well as augmenting the system with novel functionalities.

Working conditions

At the start of the traineeship your trainee plan will be set out, in consultation with your AMOLF supervisor.

AMOLF offers a special program for research internships in sustainable energy science. It is composed of a research project in one of AMOLF's research groups, combined with a series of dedicated tutorials on fundamental aspects of the science behind sustainability technology. Admission to this Academy is only possible in combination with a research internship project at AMOLF.
