Globular clusters (GCs), compact stellar systems orbiting in and around galaxies, are natural laboratories to study a diverse range of astrophysical processes. The current stellar population of the oldest GCs in our ...

Biochemical processes are conducted by interactions of individual molecules that comprise cells. It is the transient physical shape of proteins that dictates their specific functionality. However, imaging individual instances ...

The discovery of the Higgs boson in 2012 has opened up a new sector of particle physics to measurements of yet undiscovered couplings. Measurements of the numerous couplings of the Higgs boson - primarily through studies ...

In recent years, several measurement of the ratios R(D) = B(B ̄ → Dτ−ν ̄τ )/B(B ̄ → Dl−ν ̄l )andR(D∗)=B(B ̄→D∗τ−ν ̄τ )/B(B ̄→D∗l−ν ̄l ),whereldenotesanelectron or a muon, have obtained results in disagreement with the ...

This dissertation demonstrates the optical trapping and direct tracking of single nanoparticles using a plasmonic double nanohole aperture in a gold film and an all-silicon nanoantenna on a silicon substrate. For both ...

The field of genetics has grown rapidly since the isolation of the double helix complex, DNA, that provides the genetic code behind all known life. The development of methods that allow this code to be read, and more ...

The search for and characterisation of galaxies at high-redshift is a very active topic in Astrophysics. Thanks to advances in observations from space, the redshift frontier is approaching the epoch of formation of first ...

Erbium (Er) is a lanthanide element, mainly used in its trivalent ionic form (Er3+), as an active dopant in optical devices, for light amplification or generation. The luminescence of Er3+ lies within the conventional ...

This Ph.D thesis is concerned with the design, fabrication and mea- surement of silicon-on-insulator based nanowire devices that exhibit quantum effects in their operation. The devices were all formed us- ing top-down ...

The understanding of atomic structures and processes is continually improving with the great technological development in imaging techniques. Ultrafast electron and X-ray techniques are able to perform measurements at ...
