Abstract:
Previous analyses of organic peroxide explosives have focussed on identification of the explosive itself, and were performed using explosive samples synthesized from laboratory-grade precursors. In this work, analytical studies of precursors obtained from retail outlets identified compounds that could be carried over into the explosives as impurities during synthesis. Forensic and intelligence information may be gained by the identification of possible precursor impurities in explosive samples. This hypothesis was tested using triacetone triperoxide and hexamethylene triperoxide diamine prepared from domestically available off-the-shelf precursors. Gas chromatography–mass spectrometry analysis showed that compounds originating from such precursors could be detected in the organic peroxide samples at different stages in their purification. Furthermore, some compounds could also be detected in the residues of samples that had been subjected to thermal initiation.

Abstract:
When hydrogen peroxide is mixed with caustic soda, an auto-accelerating reaction can lead to generation of significant amounts of heat and oxygen. On the basis of experiments using typical pulp mill process concentration and temperatures, a relatively simple kinetic model has been developed. Evaluation of these model results reveals that hydrogen peroxide-caustic soda systems are extremely sensitive to hydrogen peroxide:caustic soda ratio, transition metal contamination, and temperature. Small changes in initial conditions can result in a closed system becoming explosive. Analysis of model results was used to develop guidelines for safer application of hydrogen peroxide in a mill setting.

Abstract:
Abstract. This paper presents an explosion-proof two-channel Raman photometer designed for chemical process monitoring in hazardous explosive atmospheres. Due to its design, alignment of components is simplified and economic in comparison to spectrometer systems. Raman spectrometers have the potential of becoming an increasingly important tool in process analysis technologies as part of molecular-specific concentration monitoring. However, in addition to the required laser power, which restricts use in potentially explosive atmospheres, the financial hurdle is also high. Within the scope of a proof of concept, it is shown that photometric measurements of Raman scattering are possible. The use of highly sensitive detectors allows the required excitation power to be reduced to levels compliant for operation in potentially explosive atmospheres. The addition of an embedded platform enables stable use as a self-sufficient sensor, since it carries out all calculations internally. Multi-pixel photon counters (MPPCs) with large detection areas of 1350 µm2 are implemented as detectors. As a result, the sensitivity of the sensor is strongly increased. This gain in sensitivity is primarily achieved through two characteristics: first, the operating principle “avalanche breakdown” to detect single photons is used; second, the size of the image projected onto the MPPC is much bigger than the pixel area in competing Raman-Spectrometers resulting in higher photon flux. This combination enables reduction of the required excitation power to levels compliant for operation in potentially explosive atmospheres. All presented experiments are performed with strongly attenuated laser power of 35 mW. These include the monitoring of the analytes ethanol and hydrogen peroxide as well as the reversible binding of CO2 to amine. Accordingly, the described embedded sensor is ideally suited as a process analytical technology (PAT) tool for applications in environments with limitations on power input.

Abstract:
Triacetone triperoxide has been synthesised for a range of experimental studies towards the reactivity, stability and gas phase metal complexation of the explosive. Reaction with transition metals was performed and a series of molten TATP experiments conducted at 120 °C. The effect of a molten state on the degradation, conformation and reactivity of TATP has been studied with the formation of diacetone diperoxide, acetone and acetic acid degradation products observed. The complexation of TATP with a range of metals has been studied by electrospray ionisation-mass spectrometry, yielding [M+Cat]+ ions for all of the alkali metals. The first observations of a [TATP+Ag]+ adduct have been made. The formation of [2TATP+Li+LiX]+ (X = Br, Cl) and [2TATP+Ag]+ sandwich complexes was also observed. Collision cross sections (CCS) for the lithium-containing complexes of TATP were measured by travelling wave ion mobility-mass spectrometry, comparing well to computationally determined structures.

Les investigations menées après attentat par les services de police technique et scientifique ont pour but d’identifier la composition de la charge explosive employée, mais la tâche peut se révéler particulièrement difficile d’un point de vue analytique. En effet, les résidus de charge explosive sont le plus souvent présents à l’état de traces dans des matrices variées et complexes, d’où la nécessité de disposer de protocoles analytiques performants et rapides. Ces travaux ont donc tout d’abord consisté à développer trois méthodes par électrophorèse capillaire pour l’analyse (i) d’anions inorganiques, puis (ii) de cations inorganiques et enfin (iii) d’anions et de cations inorganiques simultanément.

Un électrolyte de séparation très alcalin, à base de soude, a permis de séparer, mais aussi de détecter les carbohydrates via une réaction photochimique se déroulant lors du passage des analytes dans la fenêtre du détecteur. Une séparation en moins de 20 min de neuf carbohydrates a été finalement optimisée à l’aide d’une approche multivariée et d’une analyse de désirabilité. Enfin, le développement d’une méthode d’analyse de l’eau oxygénée, grâce à sa complexation avec les ions borate, a été réalisé.

Abstract:
The purpose of this thesis is to evaluate the performance and cost effectiveness of a Peroxone Groundwater Treatment Plant (PGTP) designed and operated by Montgomery Watson, in support of the Defense Evaluation Support Agency's independent analysis for the United States Army Environmental Center (USAEC). Many Department of Defense installations have sites that contain groundwater contaminated with explosive materials. Primary methods for the removal of explosive materials involve the use of Granular Activated Carbon (GAC). This process, however, requires additional waste disposal and treatment of explosive laden GAC, thereby incurring additional costs. An alternate method for the treatment of contaminated groundwater involves the use of hydrogen peroxide (H2O2) in conjunction with ozone (03). This method is referred to as the Peroxone oxidation process. A demonstration of the PGTP was conducted from 19 August to 8 November, 1996, at Cornhusker Army Ammunition Plant (CAAP), Grand Island, Nebraska using a small scale version with a maximum flow rate of 25 gallons per minute. The explosive contaminants analyzed during the demonstration include 2,4,6-Trinitrotoluene (TNT), 1,3,5-Trinitrobenzene (TNB), 1,3,5-Triazine (RDX), and Total Nitrobodies. Peroxone cost effectiveness was evaluated using a 30 year life cycle cost comparison to GAC and Ultraviolet/Ozone processes

Abstract:
Existing instrumental techniques must be adaptable to the analysis of novel explosives if science is to keep up with the practices of terrorists and criminals. The focus of this work has been the development of analytical techniques for the analysis of two types of novel explosives: ascorbic acid-based propellants, and improvised mixtures of concentrated hydrogen peroxide/fuel. In recent years, the use of these explosives in improvised explosive devices (IEDs) has increased. It is therefore important to develop methods which permit the identification of the nature of the original explosive from post-blast residues. Ascorbic acid-based propellants are low explosives which employ an ascorbic acid fuel source with a nitrate/perchlorate oxidizer. A method which utilized ion chromatography with indirect photometric detection was optimized for the analysis of intact propellants. Post-burn and post-blast residues if these propellants were analyzed. It was determined that the ascorbic acid fuel and nitrate oxidizer could be detected in intact propellants, as well as in the post-burn and post-blast residues. Degradation products of the nitrate and perchlorate oxidizers were also detected. With a quadrupole time-of-flight mass spectrometer (QToFMS), exact mass measurements are possible. When an HPLC instrument is coupled to a QToFMS, the combination of retention time with accurate mass measurements, mass spectral fragmentation information, and isotopic abundance patterns allows for the unequivocal identification of a target analyte. An optimized HPLC-ESI-QToFMS method was applied to the analysis of ascorbic acid-based propellants. Exact mass measurements were collected for the fuel and oxidizer anions, and their degradation products. Ascorbic acid was detected in the intact samples and half of the propellants subjected to open burning; the intact fuel molecule was not detected in any of the post-blast residue. Two methods were optimized for the analysis of trace levels of hydrogen peroxide: HPLC with fluorescence detection (HPLC-FD), and HPLC with electrochemical detection (HPLC-ED). Both techniques were extremely selective for hydrogen peroxide. Both methods were applied to the analysis of post-blast debris from improvised mixtures of concentrated hydrogen peroxide/fuel; hydrogen peroxide was detected on variety of substrates. Hydrogen peroxide was detected in the post-blast residues of the improvised explosives TATP and HMTD.

Abstract:
Detection canines represent the fastest and most versatile means of illicit material detection. This research endeavor in its most simplistic form is the improvement of detection canines through training, training aids, and calibration. This study focuses on developing a universal calibration compound for which all detection canines, regardless of detection substance, can be tested daily to ensure that they are working with acceptable parameters. Surrogate continuation aids (SCAs) were developed for peroxide based explosives along with the validation of the SCAs already developed within the International Forensic Research Institute (IFRI) prototype surrogate explosives kit. Storage parameters of the SCAs were evaluated to give recommendations to the detection canine community on the best possible training aid storage solution that minimizes the likelihood of contamination. Two commonly used and accepted detection canine imprinting methods were also evaluated for the speed in which the canine is trained and their reliability. As a result of the completion of this study, SCAs have been developed for explosive detection canine use covering: peroxide based explosives, TNT based explosives, nitroglycerin based explosives, tagged explosives, plasticized explosives, and smokeless powders. Through the use of these surrogate continuation aids a more uniform and reliable system of training can be implemented in the field than is currently used today. By examining the storage parameters of the SCAs, an ideal storage system has been developed using three levels of containment for the reduction of possible contamination. The developed calibration compound will ease the growing concerns over the legality and reliability of detection canine use by detailing the daily working parameters of the canine, allowing for Daubert rules of evidence admissibility to be applied. Through canine field testing, it has been shown that the IFRI SCAs outperform other commercially available training aids on the market. Additionally, of the imprinting methods tested, no difference was found in the speed in which the canines are trained or their reliability to detect illicit materials. Therefore, if the recommendations discovered in this study are followed, the detection canine community will greatly benefit through the use of scientifically validated training techniques and training aids.

Abstract:
Die vorliegende Arbeit beschreibt die Herstellung und Charakterisierung der ersten Antikörper gegen Triacetontriperoxid (TATP), einem hoch empfindlichen und unkonventionellen (nicht-kommerziellen) Initialsprengstoff. Entscheidend dafür war die Synthese eines TATP-imitierenden Haptens, welches die typische nonagonale Struktur des TATP mit seinen drei Peroxid- und sechs Methylgruppen nahezu perfekt nachbildet, aber den Vorzug einer zusätzlichen Carboxygruppe zur kovalenten Kopplung an Proteine aufweist. Dadurch konnte das TATP-Hapten an Rinderserumalbumin (BSA) gebunden werden, um ein immunogenes Konjugat zu erzeugen, welches die erfolgreiche Immunisierung zweier Säugetierarten, Maus und Kaninchen, ermöglichte. Der Verlauf der In vivo-Immunisierungen wurde durch die Analyse der Tierseren in regelmäßigen Abständen mittels enzymgekoppeltem Immunoassay (ELISA) verfolgt. Die polyklonalen Antikörper beider Spezies waren ungewöhnlich selektiv gegenüber TATP. Jedoch unterschied sich die Affinität der Antikörper der zwei Spezies um das 5000-fache, wobei die Kaninchenseren den Mausseren überlegen waren. Entsprechend war auch die mit Kaninchenserum erreichbare TATP-Nachweisgrenze von 0.01 µg/L deutlich besser im Vergleich zu 50 µg/L, die mit Mausserum erzielt wurden. Der Messbereich des TATP-ELISA mit Kaninchenserum deckte zudem mehr als vier Zehnerpotenzen ab, wie mittels Präzisionsprofil bestimmt wurde. Die erhaltenen TATP-Antikörper aus Kaninchen stehen damit Anwendungen in Nachweissystemen für die sehr empfindliche Detektion von TATP zur Verfügung, die u. a. in sicherheitsrelevanten Bereichen zum Einsatz kommen könnten. Als erste Anwendung wurde ein TATP-ELISA realisiert, der im Rahmen dieser Arbeit ausführlich optimiert wurde. Außerdem wurden erste Schritte zur Entwicklung eines TATP-Schnelltests (LFA) unternommen. Weitere Biosensoren auf Grundlage der neu entwickelten TATP-Antikörper sind denkbar.
The present work decribes the production and characterization of the first antibodies against triacetone triperoxide (TATP), a highly sensitive and improvised (non-commercial) primary explosive. Crucial to this work was the synthesis of a TATP-related hapten that mimics almost perfectly the typical nonagonal structure of TATP with its three peroxide and six methyl groups. Advantageously, it has an additional carboxylic acid group, which provides a conjugation site for covalent attachment to proteins. Thus, the TATP hapten could be linked to bovine serum albumin (BSA) to produce an immunogenic conjugate, allowing the successful immunization of two different mammalian species, mouse and rabbit. The in vivo immunization progress was followed by periodically analyzing the animals’ sera using enzyme-linked immunosorbent assay (ELISA). The polyclonal antibodies of both species were remarkably selective to TATP. The affinity of these TATP-antibodies was, however, different between the two species, with the rabbit sera showing an affinity about 5000-fold superior than the murine one. Consequently, the TATP detection limit of 0.01 µg/L was considerably better using the sera from rabbit in contrast to 50 µg/L when mouse serum was used. The working range of the TATP-ELISA with rabbit sera covers more than four decades, calculated from a precision profile. The obtained TATP antibodies from rabbit are now available for applications in highly sensitive detection systems for TATP, which could be employed, among others, in security-relevant areas. The first application was the realization of a TATP-ELISA, which was extensively optimized within the course of this work. Furthermore, the first steps towards the development of a lateral flow assay (LFA) targeting TATP were taken, making conceivable further biosensor platforms based on the newly developed TATP antibodies.

Abstract:
Entre 2014 e 2019 a União Europeia (UE) foi atingida por vários atentados terroristas, muitos de matriz islamita (Estado Islâmico), causando efeitos extremamente devastadores (e.g. Segundo a Europol no ano de 2017 ocorreram 33 ataques, nos quais registaram-se 62 mortos). Em 2018 e 2019, apesar de existir uma diminuição do número de ataques e de mortos, o terrorismo continuou a representar uma ameaça importante para os países da UE. As bombas/explosões têm sido o modus operandi na Europa que causa maior número de vítimas. Os terroristas têm recorrido sobretudo ao uso dos designados explosivos caseiros (e.g. Para a Europol, entre 2014 e 2017, as bombas/explosões, representaram mais de 80% dos incidentes terroristas jihadistas), nomeadamente, TATP (mais de 70%), sólido que resulta da junção de peróxido de hidrogénio e acetona num meio ácido. Para fabricar estes explosivos caseiros, os terroristas têm, assim, recorrido a precursores de explosivos, principalmente o peróxido de hidrogénio, e, por esta razão, este será um dos temas da nossa investigação. Deste modo, a prevenção desta prática constitui uma das prioridades da UE, através do desenvolvimento de várias medidas na ótica da política de segurança, e, consequentemente será o objetivo desta investigação identificar o tipo de medidas que têm sido adotadas pela UE na prevenção dos ataques terroristas, nomeadamente, através do incremento do controlo dos precursores de explosivos. Pretende-se, também, verificar se estas medidas têm respaldo teórico na criminologia ambiental através da aplicação de técnicas de prevenção situacional. Finalmente, o panorama português será também objeto de análise.
Between 2014 and 2019 the European Union (EU) has been hit by several terrorist attacks, many by Islamist groups (Islamic State), having a devasting impact (e.g. According to Europol in the year 2017 there were 33 attacks, in which 62 people were killed). In 2018 and 2019, has been a decrease in the number of attacks and deaths, but terrorism continued to represent a major threat in EU countries. Bombs/explosions have been the modus operandi in Europe that causes the highest number of victims. Terrorists have mainly use of so-called homemade explosives (e.g. For Europol, between 2014 and 2017, bombs/explosions accounted for more than 80% of jihadist terrorist incidents), mostly, TATP (more than 70%), solid that results from the combination of hydrogen peroxide and acetone in the presence of an acid. To manufacture these homemade explosives, terrorists use explosive precursors, mainly hydrogen peroxide, and for this reason, this will be one of the topics of our investigation. Thus, the prevention of this practice is one of the EU's priorities, by the development of various measures from the perspective of security policy, and, consequently, the aim of this investigation will be to identify the type of measures that have been adopted by the EU in preventing attacks terrorists, namely by increase the control of explosive precursors. It is also intended to verify whether these measures have theoretical support in environmental criminology by the application of situational prevention techniques. Finally, the portuguese panorama will also be the object of analysis.

Many thermal runaway incidents have been caused by organic peroxides due to the peroxy group, –O–O–, which is essentially unstable and active. LPO was first produced commercially in about 1941. LPO is also sensitive to thermal sources and is incompatible with many materials, such as acids, bases, metals and ions. When in contact with acid or combustible materials it will produce fire hazard. When heated to decomposition, it emits acrid smoke and fumes. In this study, thermal analysis instrument were employed to determine the fundamental thermokinetic parameters that involved exothermic onset temperature (T0), heat of decomposition (ΔHd), and other safety parameters for loss prevention of runaway reactions and thermal explosions. The thermal decomposition and runaway behaviors of LPO with incompatibilities such as H2SO4, HNO3 analyzed by Differential scanning calorimetry (DSC), Vent sizing package 2 (VSP2), Thermogravimetric analyzer (TGA) - Fourier transform infrared (FTIR), Thermal activity monitor III (TAM III), Gas chromatography/mass spectrometry (GC/MS) was used to obtain the thermokinetic data and analyzed the hazardous phenomena. From the thermal decomposition reaction of various concentrations of HNO3 (from lower to higher concentrations) with LPO, it emitted large energy from exploded product and NaOH decreased the onset temperature. Solid thermal explosion (STE) by thermal safety software (TSS) was employed to simulate the thermal explosion development for various types of storage tank. In view of loss prevention, thermal analysis instrument applications and model analysis to integrate thermal hazard development were necessary and useful for inherently safer design and storage and to prevent potential hazard.

Abstract:
We built three successive versions of a thermal decomposition cavity ring-down spectrometer and tested their response to explosives. These explosive compound analyzers successfully detected nitroglycerine, 2,4,6-trinitrotoluene (TNT), pentaerythryl tetranitrate, hexahydro-1,3,5-trinitro-s-triazine and triacetone triperoxide (TATP). We determined the pathlength and limits of detection for each, with the best limit of detection being 13 parts per trillion (ppt) of TNT. For most of the explosive tests, the peak height was higher than the expected value, meaning that peroxy radical chain propagation was occurring with each of the explosives and not just the peroxide TATP.
