WHAT INFLUENCE WOULD a CLOUD BASED SEMANTIC LABORATORY NOTEBOOK HAVE on the DIGITISATION and MANAGEMENT of SCIENTIFIC RESEARCH? by Samantha Kanza
UNIVERSITY OF SOUTHAMPTON Faculty of Physical Sciences and Engineering School of Electronics and Computer Science What Influence would a Cloud Based Semantic Laboratory Notebook have on the Digitisation and Management of Scientific Research? by Samantha Kanza Thesis for the degree of Doctor of Philosophy 25th April 2018 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF PHYSICAL SCIENCES AND ENGINEERING SCHOOL OF ELECTRONICS AND COMPUTER SCIENCE Doctor of Philosophy WHAT INFLUENCE WOULD A CLOUD BASED SEMANTIC LABORATORY NOTEBOOK HAVE ON THE DIGITISATION AND MANAGEMENT OF SCIENTIFIC RESEARCH? by Samantha Kanza Electronic laboratory notebooks (ELNs) have been studied by the chemistry research community over the last two decades as a step towards a paper-free laboratory; sim- ilar work has also taken place in other laboratory science domains. However, despite the many available ELN platforms, their uptake in both the academic and commercial worlds remains limited. This thesis describes an investigation into the current ELN landscape, and its relationship with the requirements of laboratory scientists. Market and literature research was conducted around available ELN offerings to characterise their commonly incorporated features. Previous studies of laboratory scientists examined note-taking and record-keeping behaviours in laboratory environments; to complement and extend this, a series of user studies were conducted as part of this thesis, drawing upon the techniques of user-centred design, ethnography, and collaboration with domain experts. These user studies, combined with the characterisation of existing ELN features, in- formed the requirements and design of a proposed ELN environment which aims to bridge the gap between scientists' current practice using paper lab notebooks, and the necessity of publishing their results electronically, at any stage of the experiment life cycle. -
Hafnium Alkylamides and Alkoxide Adsorption And
HAFNIUM ALKYLAMIDES AND ALKOXIDE ADSORPTION AND REACTION ON HYDROGEN TERMINATED SILICON SURFACES IN A FLOW REACTOR by KEJING LI A DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Chemical and Biological Engineering in the Graduate School of The University of Alabama TUSCALOOSA, ALABAMA 2010 Copyright Kejing Li 2010 ALL RIGHTS RESERVED ABSTRACT This work is a study of the gas phase and surface chemistry of three metalorganic Hf (IVB) precursors – tetrakis(dimethylamido) hafnium (TDMAH), tetrakis(ethylmethylamido) hafnium (TEMAH), and hafnium tert-butoxide (HTB) adsorption and reaction onto hydrogen terminated Si(100), Si(111) and Ge surfaces during low pressure chemical vapor deposition (CVD) in a temperature range of 25 ºC to 300 ºC in a flow reactor. The main methods used include in-situ attenuated total reflectance Fourier transforms infrared spectroscopy (ATR-FTIR), transmission IR, quadrupole mass spectrometer (Q-MS), ab inito density functional theory (DFT), photoelectron spectroscopy (XPS), finite element analysis (FEA), computational fluid dynamics (CFD), and atomic force microscopy (AFM). Possible gas phase decomposition and surface adsorption reactions were surveyed. Reaction energies, vibrational spectra and transition states were calculated for the three precursors and especially the two alkylamido hafnium precursors to support experimental observations. Interfacial bonding and surface catalyzed reaction processes initiated by the adsorption of precursors were detected. For TDMAH and TEMAH, β-hydride elimination and insertion reactions were calculated to be not favorable thermodynamically at these low experimental temperatures. Interfacial bonding during adsorption between the Si was through N-Si and/or C-Si. Decomposition products containing Hf-H species were observed on the surface at room temperature and 100 ºC and the peak assignment was confirmed by deuterated water experiments. -

Pharmacy is a subject that is running on it’s two feet: chemistry and biology. The footsteps of the both are lying side by side. Lack of one of these two subjects the balance will be disrupted. Chemistry of a drug molecule is superimposed by the biological activity of the same. Recent technology is flourishing day by day according to the progress of basic pharmaceutical science to combat with diseases caused by microorganisms and anomalies in the normal feedback system in living beings. Advanced technology is spreading rapidly to manufacture the new molecules, which could be helpful for diagnosis, treatment and cure of diseases to accept the challenge for making milestone for the new millennium. -

Automated Generation of Chemical Kinetic Mechanisms of Fischer-Tropsch (F-T) Gas-To-Liquid Fuel Surrogates
AUTOMATED GENERATION OF CHEMICAL KINETIC MECHANISMS OF FISCHER-TROPSCH (F-T) GAS-TO-LIQUID FUEL SURROGATES A Thesis Presented By Chikpezili Ebubechukwu Ajulu to The Department of Mechanical & Industrial Engineering in partial fulfillment of the requirements for the degree of Master of Science in the field of Mechanical Engineering with a concentration in Thermofluids Northeastern University Boston, Massachusetts May 2020 i ABSTRACT Environmental pollution as a result of continued fossil fuel usage has long been a bone of con- tention especially in the energy industry, particularly around transportation fuels. Transportation fuels, precisely jet fuels have long been studied to curb the production of harmful byproducts from the combustion of these fuels by proposing new jet fuel synthesis. Researchers have invested re- sources to the synthesis of alternative jet fuels that promise lower emissions of harmful gases such as NOx, SOx and particulates. Studies and research have yielded in the fruition of a catalytic process that involves the conversion of already existing gas-to-liquid fuels via the Fischer-Tropsch (F-T) synthesis for jet fuels that promise lower emissions. As a result of these strides, the oxidation of these alternative jet fuels is pertinent especially for new engine designs. Surrogate modeling of the F-T GTL fuels is proposed based on spectrometry analysis to determine the major components of the F-T GTL fuel. This study is done on the automated chemical kinetic mechanism generation and validated analy- sis of a three-component F-T GTL fuel surrogate chemical kinetic model, comprising of three primary reference fuels (PRFs); n-decane, iso-octane and n-propyl-cyclohexane. -

Curran 1Combustion Chemistry Centre, National University of Ireland, Galway, Ireland Abstract This paper discusses a brief history of chemical kinetic modeling, with some emphasis on the development of chemical kinetic mechanisms describing fuel oxidation. At high temperatures, the important reactions tend to be those associated with the H2/O2 and C1–C2 sub-mechanisms, particularly for non-aromatic fuels. At low temperatures, and for aromatic fuels, the reactions that dominate and control the reaction kinetics are those associated with the parent fuel and its daughter radicals. Strategies used to develop and optimize chemical kinetic mechanisms are discussed and some reference is made to lumped and reduced mechanisms. The importance of accurate thermodynamic parameters for the species involved is also highlighted, as is the little- studied importance of collider efficiencies of different third bodies involved in pressure- dependent reactions.
