Development of High-Pressure Calorimetry Techniques and Calorimetry Study of the Heavy-Fermion Superconductor CeSb2
… these measurements. This is especially true for calorimetry studies, for which the ambient pressure technique is predicated on the sample being in quasi-adiabatic conditions. We pioneer a new capability to perform calorimetry studies on samples that are embedded in a thermally conductive medium. …

Calorimetry at a Future Linear Collider
… is built around high-granularity Particle Flow Calorimetry that, in contrast to traditional calorimetry, uses the energy measurements for charged particles from the tracking detectors. This can only be realised if calorimetric energy deposits from charged particles can be separated from those of …

MAPS calorimetry for a future linear collider
The International Linear Collider (ILC) is intended to be a new high precision electron-positron collider operating at the TeV scale. The studies detailed within this thesis deal primarily with the development of Monolithic Active Pixel Sensors (MAPS) which could be used as the sensitive component …

Room Calorimetry as a Method of Measuring Metabolic Flexibility
… a hyperinsulinemic-euglycemic clamp and hood calorimetry. A study was performed to evaluate if room calorimetry alone could provide the same results and to examine how diet composition and exercise affect metabolic flexibility. Sixteen healthy males and females stayed overnight in a room …

Electromagnetic radiation calorimetry of thermoplastics, elastomers and composites systems
… recorded, leading to the concept of "microwave calorimetry." Low frequency dynamic mechanical and dielectric frequency-temperature spectra were obtained on the materials and combined to conveniently extrapolate structure-property relationships into the GHz region. A correlation was found between …

Isothermal Titration Calorimetry Uncovers Substrate Promiscuity of Bicupin Oxalate Oxidase
… data interpretation. Isothermal titration calorimetry (ITC) measures heat changes that occur during a reaction. Therefore, ITC can measure reaction rates where both the substrates and products are spectrophotometrically silent and when the reaction products are unknown. In this work, we …

Thermal and electrical characterization of a micro-hotplate for calorimetry
… This hotplate will be integrated into a calorimetry system that measures the heat released or absorbed by a reaction. An analytical thermal model is developed to quantify the heat transfer mechanisms between the hotplate and the environment. The analytical model is verified through …

Calorimetry and Structure-Reactivity Relationships in Hypervalent Compounds of Phosphorus and Sulfur
Phosphoranoxide 1, or its conjugate acid (10), TBP 10-P-5 species, hydrolyze to diol phosphinate 11 in boiling ethanolic KOH (72 hours); this reaction is reversed by treating 11 with aqueous HCl. Under these conditions, hydrolysis of isoelectronic-isostructural 10-S-5 sulfurane oxide 2b gave n

Development of a Hybrid Alanine-calorimetry Absorbed-dose Standard for Linac Electron Beams
The NRC primary standard water calorimeter is well-established for measuring dose to water in cobalt-60, linac photon beams and high-energy linac electron beams. However, for lower-energy electron beams, given the short range of electrons and the physical dimensions of the calorimeter, it is …

An isoperibol calorimeter for the investigation of biochemical kinetics and isothermal titration calorimetry
Isothermal titration calorimetry is a technique used to measure the enthalpy change associated with a molecular binding interaction. From these data, the binding constant for the reaction can be determined. In the scope of a larger project to design a high sensitivity instrument for collecting such …

Calcium vapour deposition on semiconducting polymers studied by adsorption calorimetry and visible light absorption
A novel UHV microcalorimeter has been used to study the interaction between calcium and three polymers: MEH-PPV, MEH-PPP and P3HT. All three polymers behave differently in their reaction kinetics with calcium. On MEH-PPV we measure 45 μJ/cm² of heat generated in excess of the heat of bulk metal …

A liquid-in-glass thermometer with sub-microKelvin resolution, and its application for calorimetry
… most direct and universal non-labeling method is calorimetry, but current calorimetric techniques are limited in resolution and throughput for pharmaceutical applications. In this thesis, a novel single-reaction microcalorimeter with optical readout, based on liquid expansion, was designed and …
