Probes in gaseous plasmas
From the time of Langmuir measurements of the current-potential characteristic of a small electrode probe immersed in a partially ionised gas have been used for the quantitative study of plasmas. The plasma parameters of interest are electron and ion temperature, electron and ion concentration, and …

Fiber inspired neural probes
… in the currently available technology for neural probes impede our progress towards a comprehensive brain activity map. The lack of understanding the brain function leads to limited options for the treatment of neurological disorders. In this thesis, I employed a two-step thermal drawing process …

Development of Endoplasmic Reticulum Targeted Probes and Red Fluorescent Probes for Detecting Zinc
<p>Zinc (Zn<sup>2+</sup>) is the second most abundant transition metal in the body and is important in various biological functions. Fluorescent sensors based on circularly permuted fluorescent proteins (cpFPs) have been previously made to detect labile, or unbound, Zn<sup>2+</sup> within the …

Cosmological Probes of Light Relics
One of the primary targets of current and future cosmological observations are light thermal relics of the hot big bang. Within the Standard Model of particle physics, an important thermal relic are cosmic neutrinos, while interesting extensions predict new light particles which are even more …

Carbon nanotube based electromechanical probes
… techniques, such as MEMS based cantilever probes have their shortcomings in terms of the lowest pitch that can be achieved, cost and yield. Given their promising mechanical and electrical properties, carbon nanotubes (CNTs) are strong candidates for future probing applications. A new class …

Probes of strong-field gravity
… inspirals (EMRIs) can be very sensitive probes of strong-field physics. Predicting observables from EMRIs must be done numerically, so accurate numerical methods are required to ensure that any comparison with measurement is not spoiled by numerical artefacts. The first investigation of …

Probes of strongly interacting plasma
… a concept of an "anomalous wind" felt by probes at rest. This phenomenon modifies previous results on the medium/probe interaction. We demonstrate that by deriving the anomalous correction to the screening length of the heavy quarkonium color potential. Finally, we discuss the strong …

High speed plasma flow about probes
A method for evaluation of the interaction between a uniform magnetic field and a compressible inviscid, electrically conducting ideal gas flow past a blunt body is presented. An experiment using a double diaphragm shock tube to produce a slug of gas with high electrical conductivity is performed …

Using Chemical Probes to Examine Cellular Activities
<p>Chemical probes are valuable tools for investigating rapid cellular processes, such as anaphase in cell division, by allowing for the modulation of protein activity over the course of minutes. In addition, resistance to chemical probes by mutation can provide insight into inhibitor binding …

MODIFIED BODIPY PROBES TO EXPLORE PEROXISOME FUNCTION
This research aims to use fluorescent BODIPY probes to measure biological function within a plant cell. In particular developing BODIPY fluors with emission at near-infrared and long wavelength that provides considerable benefit for specific organelle monitoring will be explored. The work described …

Fast photoemissive probes for shock compression spectroscopy
Fast photoemissive probes of two different varieties were designed and their behavior under shock compression was explored. The first probe was dye-doped silica microspheres, which were found to have 3.5× improved emission intensity under steady-state irradiation than the same dye in solution. When …
