Abstract:
To prevent materials from mould damage nanostructured metallic coatings were used. Silver, copper and titanium coatings were deposited on different materials. Deposition of metal from plasma flow, generated by vacuum-arc discharge, forms coating with highly dispersed polycrystalline structure. Average size of metal grains in copper or titanium coatings is ~10-15 nm, in silver coatings it reaches ~ 20-25 nm. Both paper and plastic materials with nanostructured metallic coatings showed high fungitoxicity unlike the same metal plates. The reason of that phenomenon may be that during oxygen chemisorption oxides of metals occur. Metals and their oxides formed coating with a highly polycrystalline structure and their fungi toxicity can vary.

Abstract:
1. The increased urinary excretion of porphyrins as well as of their precursors was studied in a patient with hereditary coproporphyria during two acute attacks in which symptoms differed markedly in character and severity. 2. The increase in urinary coproporphyrin was similar in the ‘mild’ and in the ‘severe’ attack, indicating a lack of correlation between coproporphyrin level and clinical symptoms. 3. Aminolaevulinic acid, porphobilinogen and uroporphyrin exhibited significantly higher values during the ‘severe’ attack than during the ‘mild’ attack. During the severe attack these three compounds were increased 18-, 14- and 46-fold, respectively, compared with increases of 3-, 3- and 8-fold, respectively, during the mild attack. 4. The striking rise in the formation of uroporphyrin was reflected in the plasma porphyrin profile, which revealed predominance of uroporphyrin. In accordance with this finding, an increase in erythrocyte porphobilinogen deaminase of 130% was recorded. 5. The fluorescence emission spectra of saline-diluted plasma (excitation of 405 nm) showed a distinct peak at 618 nm during the ‘severe’ episode and a small peak during the ‘mild’ attack, pointing to the possibility of diagnosing an attack simply by following the fluorometric screen of plasma. 6. The ‘severe’ attack of coproporphyria was treated with daily infusions of haem arginate, 3 mg/kg, every day for 4 days, at the end of which period a dramatic clinical response was observed. The relief of symptoms was found to be clearly related to the moderate decrease in uroporphyrin excretion observed rather than to the steep decline in the precursors.

Abstract:
AbstractHigh-resolution characterizations of intergranular attack in alloy 600 (Ni-17Cr-9Fe) exposed to 325°C simulated pressurized water reactor primary water have been conducted using a combination of scanning electron microscopy, NanoSIMS, analytical transmission electron microscopy, and atom probe tomography. The intergranular attack exhibited a two-stage microstructure that consisted of continuous corrosion/oxidation to a depth of ~200 nm from the surface followed by discrete Cr-rich sulfides to a further depth of ~500 nm. The continuous oxidation region contained primarily nanocrystalline MO-structure oxide particles and ended at Ni-rich, Cr-depleted grain boundaries with spaced CrS precipitates. Three-dimensional characterization of the sulfidized region using site-specific atom probe tomography revealed extraordinary grain boundary composition changes, including total depletion of Cr across a several nm wide dealloyed zone as a result of grain boundary migration.

Abstract:
AbstractIntroduction: The objective of this study was to investigate with the help of a computerized simulation model whether the treatment of an acute asthma attack can be individualized based on the severity of the attack and the characteristics of the patient. Material and Method: A stochastic lung model was used to simulate the deposition of 1 nm - 10 μm particles during a mild and a moderate asthma attack. Breathing parameters were varied to maximize deposition, and simulation results were compared with those obtained in the case of a severe asthma attack. In order to investigate the effect of height on the deposition of inhaled particles, another series of simulations was carried out with identical breathing parameters, comparing patient heights of 155 cm, 175 cm and 195 cm. Results: The optimization process yielded an increase in the maximum deposition values of around 6-7% for each type of investigated asthma attack, and the difference between attacks of different degree of severity was around 5% for both the initial and the optimized values, a higher degree of obstruction increasing the amount of deposited particles. Conclusions: Our results suggest that the individualization of asthma attack treatment cannot be based on particles of different size, as the highest deposited fraction in all three types of attacks can be obtained using 0.01 μm particles. The use of a specific set of breathing parameters yields a difference between a mild and a moderate, as well as a moderate and a severe asthma attack of around 5%.

Abstract:
The relationship between the microstructure of silicon nitride and its sensitivity to moisture was studied. The effectiveness of Si-H rich and N-H rich silicon nitride layers was measured under attack from water in vapor and liquid states. For water vapor attack, samples are exposed to vapor at 85 °C with a relative humidity of 85% during 1600 hours; for liquid water attack, samples are dipped in water at 60, 85 and 100 °C for 200 hours. The water resistance of the Si-H rich and N-H rich silicon nitride layers was evaluated by measuring: (i) the thickness of the silicon dioxide formed after their oxidation with water vapor, (ii) the rate of dissolution of the silicon nitride in liquid water and (iii) the corresponding activation of energy. This evaluation was performed by coupling spectroscopic ellipsometry, infra-red and X-ray photoelectron spectrometry analyses. The results revealed that for Si-H rich layer, 10 nm of silicon dioxide was formed during the water vapor attack; for liquid water attack, a high activation energy (0.88 eV) and a low dissolution rate were observed regardless of the water temperature. For N-H rich layers, approximatively 6–8 nm of silicon dioxide was formed and a low activation energy (0.64 eV) with a high dissolution rate were observed. All of these observations lead to the conclusion that the N-H rich layers could be less resistant to moisture because the isoelectronic relationship between Si2N-H and −H2O+ facilitated their deterioration in water. Moreover, a higher rate of nanoporosity for N-H rich layers than Si-H rich layer could complete this hypothesis.

Abstract:
Part Five of this book is devoted to silicates for several important reasons. First, silicates represent critical components of our planet and our lives. Silicon is the second most abundant element in Earth’s crust after oxygen, representing about 28% of the atoms present. As such, transformations of silicate minerals dominate much of the aqueous geochemistry of Earth. Every day, each of us encounters materials and objects the primary constituents of which are silicon oxides and related phases such as aluminosilicates. Granite facings on buildings, bricks, glass, pottery, ceramics, engineered materials used in water purification, catalysis, electronics, and even the optical fibers used in our most advanced communication systems are all silica based. Aluminosilicate minerals are even used as food additives. A key attribute of silicates that distinguishes them from most of the oxides highlighted in Parts One through Four of this book is that the Si(IV) cation is almost always present in a tetrahedral rather than in an octahedral coordination geometry. Exceptions include a few high-pressure phases such as stishovite (see Chapter 2) and a limited number of chelated Si(IV) complexes (see Section 14.3). The authors know of no stable compounds where Si(IV) is coordinated to only three oxygen atoms. The pathways for both forming and destroying silicate bonds are substantially different than for octahedral metal ions. Ligand-exchange pathways for silicate ions are via nucleophilic attack, where the coordination number increases in a transition state from four to five or even six (see Section 14.3 and Chapters 4 and 5). These contrast with pathways for octahedral metal ions, such as Al(III), where it is easier to decrease the coordination number from six to five or four in dissociative ligand exchange reactions. Of course, Si(IV) is not the only common element capable of forming tetrahedral oxide species. As outlined in Chapters 2 and 4, any cation with an ionic radius between roughly 0.03 nm and 0.055 nm can fit within the tetrahedral void between four close-packed oxygen anions, as expressed by Linus Pauling’s First Rule of coordination chemistry (see Chapter 2).

Abstract:
Esters are emitted directly into the atmosphere from both natural and anthropogenic sources and are produced during the atmospheric oxidation of ethers. Methyl acetate and ethyl acetate have found widespread use as solvents. Vegetable oils and animal fats are esters. Transesterification of vegetable oils and animal fats with methanol gives fatty acid methyl esters (FAMEs) which are used in biodiesel. Many esters have pleasant odors and are present in essential oils, fruits, and pheromones, and are often added to fragrances and consumer products to provide a pleasant odor. Table VII-A-1 provides a list of common esters and their odors. It is surprising to note that despite their ubiquitous nature, volatility, and fragrance, it is only very recently that quantitative measurements of esters in ambient air have been reported (Niedojadlo et al., 2007; Legreid et al., 2007). The atmospheric oxidation of saturated esters is largely initiated by OH radical attack. Reaction with O3 and NO3 radicals contributes to the atmospheric oxidation of unsaturated esters. As discussed in chapter IX, UV absorption by esters is only important for wavelengths below approximately 240 nm and, hence, photolysis is not a significant tropospheric loss mechanism. When compared to the ethers from which they can be derived, the esters are substantially less reactive towards OH radicals. The ester functionality —C(O)O— in R1C(O)OR2 deactivates the alkyl groups to which it is attached with the deactivation being most pronounced for the R1 group attached to the carbonyl group. The atmospheric oxidation mechanisms of the esters are reviewed in the present chapter. The reaction of OH with methyl formate has been studied by Wallington et al. (1988b) and Le Calvé et al. (1997a) over the temperature range 233–372 K. Data are summarized in table VII-B-1 and are plotted in figure VII-B-1. The room temperature determination of k(OH + CH3OCHO) by Wallington et al. is in agreement with that by Le Calvé et al. (1997) within the experimental uncertainties. Significant curvature is evident in the Arrhenius plot in figure VII-B-1.

Abstract:
Cummins recognized a sales growth opportunity in the gas compression market place in 2001. Natural Gas Engine Engineering then started developing the smallest displacement engines in the product line first. These are engines in the 37 to 225 kilowatt range and were introduced successfully into the market place over the last four years. Two years ago, the next step up in horsepower, the 19 liter, inline six cylinder KTA 19GC engine at 313 kilowatt was released for production. Marketing then determined that the 450 to 670 kilowatt market was underserved and decided to develop the V12 version of the KTA 19GC, the KTA38GC, to fill this need. It was recognized early in the program that the engine needed to be simple and robust because engine uptime is at a premium in the higher horsepower segments of this market. Thus, simple, robust and proven components were chosen for the engine. The project team started with the KTA38 diesel engine. The team then added the KTA19GC power cylinder components. Next, an ignition system, air/ratio control system and an electronic integrated throttle/governor system were added. These were all “off the shelf” components. When adding these components, an emphasis was placed on simplicity, user friendliness, and self diagnostics with or without a laptop computer. The engine development team was located in Columbus, IN and Clovis, NM, the design team was located in Daventry, England (the final manufacturing location) and Columbus, IN and the analysis team in Pune, India. In addition, our lead customer and distributor, both located in Texas, were closely involved in the project and added considerably to its success. The efforts of these five locations were coordinated in Columbus, IN.

Abstract:
Abstract With increasing complexity involved in advance node semiconductor process development, dependability on parametric test structures has also increased significantly. Test structures play a predominant role throughout the entire development cycle of a product. They are used to understand the process windows and also help to monitor the health of a line. This work provides a process flow sheet for root cause identification on chain opens on advanced 20 nm and sub-20 nm technologies setting a standard guideline for a specific category fail type. It provides a consistent way of attack in a much more streamlined fashion. Further, dependability on TEM rather than convention FIB cross-sections provides shortest time to root cause identification. Three typical cases encountered are discussed to demonstrate the idea: embedded chain opens by electron beam absorbed current (EBAC) isolation, chains opens at level by EBAC isolation, and chains opens at level by passive voltage contrast isolation.

Abstract:
Abstract The authors use electron spectroscopy for chemical analysis and Auger electron analysis to study the interaction of Cl and F with Al thin-films deposited as thin-films on Si wafers and as Al bondpads. The motivation behind the study is F contamination being the putative source of poor throughput at wafer probe. F species stemming from NH4F and XeF2 exposure behave quite differently from HF on the Al surface. Whereas HF tends to attack the Al metal and leave an extended oxygenated-fluorinated surface, NH4F and XeF2 promote the formation of a stable, non-deliquescent fluoride salt of aluminum. HCl is far less corrosive to Al than HF, leaving a thin chlorinated-oxygenated surface. Immersion of Al thin-films in tetra-methyl-ammonium hydroxide (TMAH) and NH4OH provided non-halogenated surfaces for comparison. With exposure to air, the surface coated with the fluorinated Al salt (NH4F) adsorbs oxygen from the air to form a segregated AlF3/Al2O3 bilayer that remains stable with a total thickness on the order of 5 nm to 10 nm. Furthermore, wafers treated with NH4F display stellar throughput performance at wafer test despite having surface F contamination. A mechanical rather than chemical model is proposed to explain the improved performance at wafer probe with the immersion of wafers in a bath containing fluoride salts before wafer probe.
