Policy Makers’ Influence On The Emergence Of A New Scientific Discipline: The Case Of Nanotechnology In Ireland, Nicolas Battard
Policy Makers’ Influence On The Emergence Of A New Scientific Discipline: The Case Of Nanotechnology In Ireland, Nicolas Battard
Doctoral
Science has undergone tremendous changes since World War II with the blurring of boundaries between science, government, and industry, as well as the so-called convergence of scientific disciplines. Nanotechnology is an illustrative example of this phenomenon. Boundaries between all these spheres are challenged, renegotiated, and reshaped under the influence of the multiple actors involved. I question here the extent to which nanoscience and nanotechnology (N&N) are emerging as a new scientific discipline under the influence of science and technology policies. With the study of N&N in Ireland from the late 1990s onwards, a focus is placed on both the macro-meso …

Selective Solubilisation Of Single Walled Carbon Nanotubes Using Polycyclic Aromatic Hydrocarbons, Sourabhi Debnath

Single-walled carbon nanotubes (SWCNTS) are proposed to be one of the most promising nanomaterials, with unique electronic and mechanical properties which lend themselves to a variety of applications. In all cases the quality of the SWCNT material is important, and for some applications it is paramount. Despite sustained efforts, all currently known SWCNT synthetic techniques generate significant quantities of impurities. They also grow in bundles or ropes and are largely insoluble in common organic solvents. SWCNTS can have a range of structures and their electronic properties (metallic or semiconducting) depend on their structure and as well on their diameters. Currently …
Physiochemical Indicators Of Single Walled Carbon Nanotube Toxicity, Alan Casey
Physiochemical Indicators Of Single Walled Carbon Nanotube Toxicity, Alan Casey
Doctoral
Numerous toxicity studies have been conducted to date both in vivo and in vitro on refined and raw Single Walled Carbon Nanotubes (SWCNT). Differences in SWCNT toxicity and biocompatibility have been observed between these studies, and whilst these discrepancies have been attributed to factors such as varying percentages of remnant catalytic particles, differences in dispersion methods etc. the mechanisms underlying these inconsistencies have not been investigated. This study used standard spectroscopic and cellular techniques to elucidate the origins of these inconsistencies and also to estimate the validity of toxicological data evaluated form standard cytotoxic endpoints. Spectroscopic studies were conducted in …
