Abstract:
The primary objective of this study was to synthesize and characterize novel silicon-based silyl organic compounds in order to gain a deeper understanding of their potential applications and interactions with other compounds. Four new artificial silyl organic compounds were successfully synthesized: 1-O-(Trimethylsilyl)-2,3,4,6-tetra-O-acetyl-β-d-glucopyranose (compound 1), 1-[(1,1-dimethylehtyl)diphenylsilyl]-1H-indole (compound 2), O-tert-butyldiphenylsilyl-(3-hydroxypropyl)oleate (compound 3), and 1-O-tert-Butyldiphenylsilyl-myo-inositol (compound 4). To thoroughly characterize these synthesized compounds, a combination of advanced mass spectrometric techniques was employed, including nanoparticle-assisted laser desorption/ionization mass spectrometry (NALDI-MS), Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS), and triple quadrupole electrospray tandem mass spectrometry (QqQ ESI-MS/MS). These analytical methods enabled the accurate identification and characterization of the synthesized silyl organic compounds, providing valuable insights into their properties and potential applications. Furthermore, the electrospray ionization–Fourier transform ion cyclotron resonance–tandem mass spectrometry (ESI-FT-ICR-MS/MS) technique facilitated the proposal of fragmentation pathways for the ionized silyl organic compounds, contributing to a more comprehensive understanding of their behavior during mass spectrometric analysis. These findings suggest that mass spectrometric techniques offer a highly effective means of investigating and characterizing naturally occurring silicon-based silyl organic compounds, with potential implications for advancing research in various fields and applications in different industries.

Abstract:
Abstract This thesis is focused on the hydrolysis of aluminium, the polymerisation of the hydrolysis products, and how these can be monitored by mass spectrometric methods. The main aim of this research is to figure out how the aqueous speciation of aluminium changes as a function of pH (3.2–10), concentration (1–100 mM), reaction time (1s–14d), and counter anion (Cl-, SO42-, HCOO-). The method used was electrospray mass spectrometry. The results showed more variable speciation than those suggested earlier. The main species were Al2, Al3, and Al13, which were found in all of the conditions under scrutiny. The effect of pH was the most remarkable of all the parameters researched. The formation of large highly charged complexes was strongly dependent on it. Also the Al-concentration in the bulk solution had a clear effect on speciation: in dilute solutions there were more protonated ligands and less attached counter anions. This could mean that the species in more diluted bulk solutions had fewer different states of charge. Reaction time caused only minor changes to speciation in the initial pH: there was slightly more variation of a certain sized species in the aged solution. In elevated pH, the birth of important Al13 oligomers was time dependent. The effect of the counter anion was tremendous. In a chloride environment the speciation was rich and diversified. With sulphate the speciation was limited to solid- like compounds, and the variation of single-sized species was almost lacking. The formate as a counter anion caused most surprising results; the charge of aluminium in some studied complexes was lowered from the common 3+ to 1+. If this reaction also occurs in natural circumstances, the uses of aluminium formate would be wide. The results can be utilised in following the progress of dissolution, the mobilization and toxicity of aluminium in natural waters, as well as in water purification, and in reaching minimal chemical contamination levels in sludge as well as in aqueous waste.

Abstract:
Measurements of the signals proportional to the radiation intensities or the number densities of the charged particles in argon ICP plasma are between the most popular methods of analysis of low concentrations of elements. But the relationships between the signals and the quantity of element in the sample are very complicated, depend on many physical phenomena and chemical reactions and must be calibrated by application of the reference materials. The accuracy of analysis depends on the level of agreement between the compositions of the RM matrices and the sample. As the exact matching is not possible the signal formation in the argon plasma and the effects of matrices on the analytical results should be studied. A method of calibration of the dependence of the sensitivity of the mass spectrometer on the ion masses and methods to determine the electron density and temperature from the mass spectrometric measurement data were proposed. Those aid estimation of the ion signals for analysis and assessment of the measurement uncertainty. The largest matrix effects usually are due to easy to ionize elements. The results show that those elements in argon plasma, depending on the ionization potentials and the structure of the atomic energy levels, differ in possibilities to increase the temperature, the temperature and density gradients, deviation from the local thermodynamic equilibrium, take part in charge transfer reaction between doubly ionized ions and argon atoms. The phenomena... [to full text]
Mažos elementų koncentracijos šiuo metu dažniausiai yra nustatomos fizikiniais metodais. Dažnai matuojamas spinduliuotės stipris arba elektringų dalelių skaičius. Tačiau ryšys tarp signalo dydžio ir elemento atomų kiekio yra labai sudėtingas daugelio fizikinių (garavimo ar dulkėjimo, disociacijos, atomų sužadinimo bei jonizacijos, srautų ir kt.) reiškinių bei cheminių reakcijų rezultatas. Jų išeiga kol kas pakankamu tikslumu negali būti numatyta. Todėl tokie matavimai yra tik santykiniai, t.y. jie kalibruojami etaloninėmis medžiagomis. Kalibravimo tikslumas priklauso nuo to kiek bendroji etaloninės medžiagos sudėtis artima tiriamajai medžiagai. Tai įmanoma padaryti tik tam tikru artutinumu. Todėl darbe tiriamos signalo formavimosi sąlygos indukcinėje argono plazmoje ir paskirų paveikiųjų elementų bei bendros bandinio sudėties įtaka bandinių analizinių masių spektrometrinių matavimų rezultatams. Pasiūlytas būdas masių spektrometro jautrio priklausomybei nuo jono masės kalibruoti bei būdai elektronų temperatūrai ir koncentracijai nustatyti iš jonų spektrometrinių matavimų. Tai leidžia įvertinti jonų signalus santykinei pusiaukiekybinei analizei, padeda nustatant matavimų neapibrėžtis. Nustatyta, kad labiausiai analizinį signalą argono plazmos šaltiniuose įtakojantys lengvai jonizuojami elementai, priklausomai nuo jų jonizacijos potencialų ir atominių energijos lygmenų išsidėstymo, gali padidinti plazmos temperatūrą ir gradientus bei nukrypimus nuo dalinės termodinaminės...

Abstract:
The detection, identification, and analysis of biological materials in "real time" is of significant current interest in a number of fields. As with chemical materials, mass spectrometry holds great promise for such applications. We are presently engaged in a study of approaches to mass spectrometric analysis of biological materials, utilizing laser desorption/vaporization/ionization in conjunction with Fourier transform mass spectrometry. In this presentation, we focus on laser desorption/ionization applied to peptides. Although laser desorption can generate mass spectra with reasonably abundant molecular ion for relatively small peptides in the pure state, use of matrix-enhanced desorption techniques facilitates greatly the generation of molecular ion, We demonstrate this using examples of 248 nm laser desorption mass spectra of polypeptides. The nature of the substrate from which ions are desorbed is found also to be an important factor in the desorption/fragmentation processes through a study of a range of metallic supports. Thermal conductivity of the substrate appears to be the key parameter.

Abstract:
A major new research facility consisting of a low-pressure burner apparatus has been constructed at the Ballistic Research Laboratory to study the detailed flame chemistry relevant to the gaseous flames of burning propellants. Experimental results provide temperature and species profiles that are necessary to validate flame models being developed to simulate propellant combustion. This facility is an integrated apparatus that consists of various diagnostic tools which include laser spectroscopy, Fourier transform infrared spectroscopy, and molecular beam triple quadrupole mass spectrometry. In this paper, we report on spatially resolved temperature and species profiles obtained in premixed H2/N2O/Ar and H2/NO2/Ar low-pressure flames (20 Torr). The temperature measurements were obtained by laser-induced fluorescence (LIF) of OH radical employing its (A2Σ+–X2Π) (1,0) band near 281 nm. Temperatures were abstracted from a Boltzmann energy simulation and compared with those obtained with Pt/Pt-Rh(10%) thermocouples coated with noncatalytic beryllium/yttrium oxide. Species profiles include H, H2, O, OH, N2O, NO, NO2, O2, H2O and NO2. Profiles for radical species such as OH and NO are compared with those obtained with LIF and/or resonant-enhanced multiphoton ionization to ensure that there are no systematic errors in a given technique.

Abstract:
A case study of the ion-assisted etching of silicon by chlorine is presented as a prototype of a class of ion-assisted etching processes. In contrast to the more well studied Si-F system, and other F atom etching reactions, Cl etching processes are much more dependent on energetic ion impact of the surface. We will examine aspects of chlorine adsorption to silicon, sputtering of adsorbed chlorine atoms, incorporation fo chlorine into the silicon crystal lattice, and formation and removal of SiClx etch products. In-situ SIMS, ISS, and modulated beam mass spectrometric measurements, and post etch RBS and XPS analysis of the altered surface are used to examine the dynamics of the etching process and the state of the altered surface layer produced by ion bombardment.

Abstract:
Carbon is a versatile building element of many interesting materials that have already find practical applications in the form of thin films (diamond, DLC) or potential applications in the form of nanostructures (fullerenes, carbon nanotubes, graphene). For electronics or sensors, it is important to provide a very good contact to the functional structures. Gold is the best choice taking into account its inertness, i. e. oxidation resistance. From this point of view the investigation of the growth of carbon materials on gold is important. The carbon-gold interaction plays an important role in different fields of electronics such as atomic force microscope lithography, bioelectronics or semiconductor industry. Research in this field is developing rapidly e. g. the modification of interface structure and contact resistance between a CNT and gold electrode was recently modified by Joule melting and amorphous C-Au nanocomposite thin films were deposited by dc magnetron co-sputtering. Herein we report on the preparation and characterization of the carbon nanocomposites which were synthesized on gold substrate from methane precursor using low pressure thermal chemical vapor deposition technique and two different plasma-enhanced chemical vapor deposition (PECVD) methods. The former one PECVD proceeded in microwave reactor at low pressure and the latter one was carried out using non-thermal atmospheric pressure plasma jet (ntAPPJ). Presented approach is based on the deposition of carbon material on gold instead of the deposition of gold on carbon material which is more common. Surprisingly, we didnt find similar studies dealing with the synthesis of carbon nanocomposites using direct deposition from hydrocarbon precursor on the gold thin _lm. The surface morphology was studied by high resolution scanning electron microscopy (HRSEM). Depth-structure profile including the film thickness was observed using the focused ion beam ablation. Energy-dispersive X-ray spectroscopy (EDX), infrared reflection absorption spectroscopy (IRRAS) and laser desorption-ionization time of flight mass spectrometry (LDI-TOF MS) were used to study the chemical properties. Gold and carbon related clusters were observed by means of mass spectrometric study.

Abstract:
A comprehensive study of Mississippi Valley-type base-metal deposits across the Canadian Cordillera was done to compare and contrast their features. Extensive dissolution of host rocks is followed by multiple generations of dolomite cements from early, low-temperature, fine-grained to coarser, higher temperature types that overlap with Zn-Pb sulfide minerals; late-stage calcite occludes residual porosity. Dolomite is generally chemically stoichiometric, but ore-stage types are often rich in Fe (&amp;lt;1.3 weight per cent FeO) with small sphalerite inclusions. Sphalerite-hosted fluid inclusions record ranges for homogenization temperatures (77-214°C) and fluid salinity (1-28 weight per cent equiv. NaCl±CaCl2). These data suggest fluid mixing with no single fluid type related to all sulfide mineralization. In situ secondary ion mass spectrometry (SIMS) generated delta-18OVSMOW values for carbonate minerals (13-33 permille) reflect dolomite and calcite formation involving several fluids (seawater, basinal, meteoric) over a large temperature range at varying fluid-rock ratios. Sphalerite and pyrite SIMS delta-34SVCDT values vary (8-33 permille) but in single settings have small ranges (&amp;lt;2-3 permille) that suggest sulfur was reduced via thermochemical sulfate reduction from homogeneous sulfur reservoirs. Collectively, the data implicate several fluids in the mineralizing process and suggest mixing of a sulfur-poor, metal-bearing fluid with a metal-poor, sulfide-bearing fluid.
