Design of an Advanced Headform for the Prediction of Eye and Facial Injuries( Book )

2 editions published in 2006 in English and held by 2 WorldCat member libraries worldwide

The Virginia Tech - Wake Forest, Center for Injury Biomechanics is in the second year of a multi-year research effort focused on predicting face and eye injury resulting from blunt impacts. The primary thrust of this effort is the development of physical headform capable of measuring face and eye impact loads. In order to assess the capability of protective equipment in reducing eye and facial injuries, the FOCUS headform is being developed with the capability of predicting fracture of facial bones, as well as eye injuries from impact loading. The headform will be used by the United States Army to test and evaluate various protective devices and other equipment to assess the likelihood of these devices to prevent, or possibly cause, an eye or facial injury. It is expected that this headform will be used by researchers and engineers in other disciplines as well; for instance, this headform can be used to evaluate the injury potential of sports equipment or the effectiveness of automotive safety systems
Conversion of Ozone-Depleting Substances (ODS) to Useful Products: Design of a Process for Conversion of Halons 1211 and 1301 to HFCS. Part A( Book )

2 editions published in 2003 in English and held by 2 WorldCat member libraries worldwide

The contractor will investigate two processes for the conversion of Cf3Br to Cf3I and perform a detailed analysis of the practical implementation of adapting these technologies to full scale production including reactor design (kinetic variables, heat and fluid flow characteristics and non-ideal flow, multiple step reactions, etc) and construction of the reactor itself
The use of LDI-TOF imaging mass spectroscopy to study heated coal with a temperature gradient incorporating the plastic layer and semi-coke( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: This work has used high range imaging mass spectrometry to study a coal sample that has undergone heating with a temperature gradient. A custom made hotplate was heated to 1000 °C and the coal was allowed to heat naturally through conduction to produce a large thermal gradient typical of conditions in a coke oven. The sample was quenched, sectioned and analysed using laser desorption time of flight imaging mass spectrometry (LDI-TOF-IMS) to study the molecular changes that occur within the plastic layer and in the semi-coke. The raw coal was observed to have a molecular weight range between 500 and 20, 000 Da with a peak occurring at 2000 Da. The plastic layer was observed to have a prevalence for increasing 500–1000 Da structures though this formed part of the larger molecular weight range. Resolidification of the plastic layer coincided with a rise in 4000 Da structures. The semi-coke spectrum had a series of repeating peaks separated by 24 Da extending from 1000 Da to 3000 Da. This was considered evidence of broad molecular ordering. A second phenomenon was observed in the semi-coke associated with low range molecular weights (50–300 Da). This appeared as high intensity signals in a molecular range typically considered as ion fragments (being too low in size to remain in the high vacuum environment). It was speculated that these low range structures may be associated with the coking of volatile tars exiting the hot-side of the plastic layer through high temperature semi-coke. Overall, this preliminary work provides a novel methodology to study the heating impacts during coking on a molecular level

Separation and analysis of high range extractable molecules formed during coal pyrolysis using coupled thin layer chromatography-imaging mass spectrometry (TLC-LDI-IMS)( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: A new coupled thin layer chromatography-imaging mass spectrometry method was developed to investigate solvent extracts from a coal. The technique was used to assess the separation of complex molecular structures in a tetrahydrofuran (THF) soluble extract taken from a semi-coke (the solid residue obtained after thermal pre-treatment of coal at 430 °C). Thin layer chromatography (TLC) was then used with acetone as a mobile phase and silica as a stationary phase. The component separation was determined by laser desorption/ionisation time-of-flight imaging mass spectrometry (i.e. TLC-LDI-IMS). This provided the molecular weight distributions and spatial concentrations of coal derived structures observed over the TLC plate. In general, acetone lifted and concentrated lighter molecular species in the range of 200–500 Da by up to 55% compared to the THF extract. Structures of 500–1000 Da in molecular weight were lifted, but to lesser extent, distributing these more evenly across the TLC plate. The structures observed in the acetone-concentrate repeated every 12–14 Da as in a homologous series, similar to previous studies. Residual material remaining in the sample (unascended by the mobile phase) showed repeating structures every 24 Da from 600–3000 Da, also similar to previous work. A novel methodology was also evaluated using the TLC plate as a heated substrate for inducing and studying cross-linking reactions. Acetone soluble material between 200–500 Da was loaded onto the TLC plate and heated to 250 °C. This was found to convert the low molecular weight compounds into more complex structures between 1500 and 4000 Da. Direct use of a MALDI-suitable TLC plate as a reaction surface provided a means of characterising the high molecular weight products without the need for a solvent to transfer material onto a second MALDI analysis plate. This avoided limitations in molecular weight with solvent solubility. Overall, the TLC-LDI-IMS method was shown to be a suitable method for tracking the separation and potential cross-linking mechanisms involved in coal derived extracts
