Vanillin (4-hydroxy-3-methoxybenzaldehyde) is the main component of natural vanilla and a relevant substance in the flavoring and aromatic industries. This study presents a kinetic model to explain both vanillin and vanillic acid concentrations achieved in the alkaline oxidation of pine kraft lignin. Considering that they come from the same precursors, this approach allows an understanding of vanillin production with reaction conditions that minimize the vanillic acid pathway directly from the lignin oligomers, thus maximizing vanillin production.

Abstract:
In this study, CuO nanostructured films conjunction with metal doping have been deposited onto soda lime glass (SLG) substrate by method of spin coating at different doping concentration in solution (0%, 2% and 4%). X-ray diffraction (XRD) patterns for copper oxide films conjunction with Al doping demonstrated that the films have polycrystalline structure and have preferential growth in (-111) and (200) directions. Calculated dislocation density value of (-111) plane is changed between 3.7 x 1014 and 5.83 x 1014 m-2 and 83.7 x 1014 and 50.6 x 1014 m-2 for (200) owing to the expansion of structural parameters with Al dopant content in solution. In order to investigate surface morphology, we used an atomic force microscopy (AFM). The obtained results from AFM revealed that samples are comparatively smooth in the valley area while many crystals-like structures are seen in the hill area. In order to examine absorbance, energy band gap and transmittance value of Al doped CuO films, we used a UV-Vis measurements system in the range of 1100-300 nm at temperature of 273 K. The obtained samples have high absorption in the region of UV-Vis and have a high affinity for UV light. It can be said that the change in the absorption value is a result of the different crystal nature of the samples. Energy band gap value of Al:CuO thin films changed between 1.98 and 2.07 eV.

Abstract:
It is well known that alkali metal binary GICs adsorb gaseous species (H2, N2, Ar, CH4, etc.) physisorptively at low temperatures, where physisorbed gaseous molecules are accommodated in the interstitials of the alkali metal lattice within the graphitic galleries (Lagrange and Hérold, 1975; Lagrange et al., 1972, 1976; Watanabe et al., 1971, 1972, 1973). The capacity for hydrogen adsorption, which is estimated at 144 cm3/g in KC24, for example, is large and comparable to the capacity in other adsorbers such as zeolite or activated charcoal. Interestingly, the physisorption phenomenon in alkali metal GICs has different features from that in conventional adsorbents such as zeolite or activated charcoal; that is, guest molecules in alkali metal GICs are not simply bonded to the adsorbents through weak van der Waals forces without any change in the electronic structures. Here we discuss the gas physisorption phenomenon in alkali metal GICs from general aspects, in relation to their specific features. Then in subsequent sections, we will give details of actual cases. Hydrogen is a typical gaseous molecule adsorbed in alkali metal GICs. Hydrogen physisorption takes place at low temperatures below about 200 K, where hydrogen molecules are accommodated in the graphitic galleries and are not dissociated into atomic hydrogen species. When the temperature is increased to over 200 K, the alkali metal GICs work as catalysts to hydrogen, resulting in the occurrence of hydrogen chemisorption. Hydrogen physisorption will be discussed in Section 8.1.2, hydrogen chemisorption and related issues have been discussed partly in Sections 2.2.1 and 5.4.1 from the viewpoints of structure and electronic properties, and will be discussed again in Section 8.1.2. Figure 8.1 represents the composition dependence of the amount of physisorption of hydrogen molecules in KCm at 77 K (Lagrange and Hérold, 1975). The composition of 1/m = 1/8 corresponds to the stage-1 compound and the composition 1/m = 1/24 to the stage-2 compound; intermediate compositions between 1/8 and 1/24 are considered to have a mixed structure of stage-1 and stage-2 compounds. The stage-1 compound does not adsorb hydrogen at all.

Abstract:
Energy storage devices are essential because of ever-worsening fossil fuel depletion, increasing energy demand, and increasing environmental pollution. Maxwell Technologies, NessCap, Ashai Glass, and Panasonic commercialize carbon-based conventional supercapacitor devices. Carbon materials like graphene, carbon nanotubes, and activated carbon, are considered favourable materials for bendable and wearable electronic devices. The graphene, because of its high conductivity (thermal ~5 × 103 W m-1 K-1, electrical ~102 to 108 S m-1), extraordinary surface area (theoretically ~2630 m2 g-1), outstanding electrochemical performance (100 to 200 F g -1), less weight compared to transition metal oxides (because of less molecular weight of the carbon), outperform every other carbon material [1, 2]. The fiber-shaped supercapacitors are considered a potential future candidate for electrochemical energy storage systems and have gained considerable attention from the energy storage research community. This chapter discusses the importance of fiber-shaped supercapacitors, their evolution, various forms of their device structures, and electrolytes used for fiber-shaped supercapacitors. Further, the wet-spinning technique for synthesizing graphene fibers and their composites with pseudo-capacitive materials are also discussed.

Full text
Abstract:
Abstract The Mulatos district is a volcanic-hosted, advanced argillic, gold enargite system of late Oligocene age, located in the northern Sierra Madre Occidental volcanic province of Sonora, Mexico. Hypogene mineralization is associated with rhyodacite domes and major faults. Gold is associated with pyrite ± enargite in distinct pods of vuggy silica-pyrophyllite-diaspore-dickite in altered dacite-rhyodacite volcanic rock. Past production of more than 300,000 oz Au and reserves of more than 2.3 Moz make the district one of the largest gold systems in northern Mexico and one of the larger advanced argillic gold systems in the world. To the west of Mulatos, five other similarly altered systems are present, and these systems provide additional insight into the genesis and possible variations in mineralization, level of exposure, and physio-chemical conditions of formation. Unlike many acid-sulfate systems, hypogene alunite is uncommon at Mulatos and instead the main alteration mineral is pyrophyllite. The district was tilted ˜15° to 25° NE after mineralization, exposing >1 km of a mineralized and variably altered section. Advanced argillic alteration (>3 km2) can be traced laterally outward through intermediate argillic (>5 km2) into chlorite-montmorillonite ± epidote. Prominent silicified ridges and red (oxidation of pyrite) hills with kaolinite and scattered barite veinlets characterize the surface expression above ore zones. The age of mineralization is bracketed between 31.6 Ma mineralized tuffs and 25 Ma crosscutting and overlying unaltered basaltic andesites. Ore minerals include free gold, Au-rich pyrite, enargite, sphalerite, and less commonly, tennantite, Au telluride, covellite, and chalcopyrite. Elevated concentrations of Ag, As, Au, Ba, Cu, Hg, Mo, Sb, and Te are common in a 2-km2 alteration zone surrounding the mineralized centers. Mass balance calculations based on whole-rock studies of progressively altered samples show decreasing Ca, K, and Na and increasing Si and Al associated with intensifying acid leaching. The apparent increase in Si and Al is likely a consequence of cation leaching related to the low-pH hydrothermal fluids rather than element addition. Early Au with pyrite, followed by auriferous pyrite + enargite ± Ag sulfosalts, and late Au-containing barite make up the three principal ore stages. Stratigraphic reconstructions show that the tops of the shallowest orebodies are structurally controlled, thin, high-grade pyrite-barite, Au telluride, and Au pyrite + quartz veins formed at a depth of <200 m, whereas the top of the main Mulatos orebody (Cerro Estrella) formed at ˜600 m and continues downward for >400 m. Deep mineralization is dominantly lithologically controlled with large, low-grade (1–2 g/t Au) substratiform horizons coincident with stratigraphic contacts and specific lithologic facies. Higher grade quartz-pyrophyllite-pyrite-Au subvertical elongate zones feed the lateral mineralization. Cerro Estrella ore horizons are not distinctive veins, but 10- to >80-m-wide vuggy silica-pyrite pods surrounded by dickite-pyrophyllite-pyrite zones. Beneath the Au ore, rare chalcopyrite veinlets with traces of quartz-illite selvages cut dacite flows and possible dikes. Phase equilibria indicate that hydrothermal fluids were extremely acidic (pH <2) with temperatures of ˜260° to 300°C. Stable isotopes suggest fluid mixing between magmatic and meteoric components, with increasing meteoric input during waning stages, including the period of high-grade Au barite mineralization. Sulfur isotopes of near zero for pyrite (δ34S = –4 ‰) and 18 per mil for coexisting barite give equilibrium temperatures of 260° ± 10°C and are consistent with a magmatic sulfur source. Supergene oxidation in the upper 100 to 200 m of mineralized zones has redistributed copper into small chalcocite layers and liberated Au from pyrite-forming native Au + earthy brown hematite in an oxidized cap.

Abstract:
Abstract The Nansatsu district of southern Kyushu has been the site of calc-alkaline volcanism for the last 10 m.y., shifting eastward with time. Associated hydrothermal activity followed deposition of the volcanic host rocks by about 0.5 m.y. and was characterized by interaction of magmatic fluids with meteoric water under epithermal conditions, resulting in the formation of high sulfidation Cu-Au deposits at Kasuga, Iwato, and Akeshi. The orebodies consist of >95 wt percent SiO2 and result from leaching of the original andesite lava and pyroclastic flows by acid chloride-sulfate waters. These are inferred to have formed when magmatic vapors containing HCl and SO2 condensed into meteoric water. The residual silica (now quartz) orebodies are best developed where the host was initially permeable. The margins of the quartz bodies are abrupt, with narrow (1-2 m) halos representing the reaction front of acid waters isochemically dissolving the host rock. The halo comprises alunite (strongly zoned in Na and K, with P-rich cores), dickite, and/or kaolinite ± pyrophyllite, grading out into illite and interlayered illite-smectite clays, and finally, propylitic alteration. This pattern is characteristic of deposits of this type throughout the world, for example, at Summitville, Colorado, and Lepanto, Philippines. Mineralization occurred after initial leaching by the vapor condensates, with metals transported by a dense magmatic fluid. Mixing with meteoric water and the subsequent temperature decrease caused the general decrease in grade toward the margin of the quartz bodies; ore grades are restricted to the quartz bodies. Gold is most closely associated with enargite and pyrite; later minerals include covellite and then sulfur. The last stage of activity was steam-heated, with descending waters oxidizing sulfides to goethite and locally remobilizing Au into fractures (this varies in degree between deposits). Erosion exposed the orebodies to supergene weathering, continuing the sulfide oxidation and Au remobilization. Stable isotope results indicate that hypogene alunite formed from a mixture of magmatic fluid (δ18O = 7 ± 2‰, δD = −25 ± 5‰, similar to nearby active volcanic discharges) with local meteoric water. In contrast, the clays in the marginal halo have isotopic compositions indicating a δ18O shift of 6 to 8 per mil from local meteoric water values, probably due to water-rock interaction, and the δ18O values of residual silica quartz may also be due to meteoric water domination. Fluid inclusion study of postmineralization quartz crystals indicates that the fluids had a salinity of about 1 wt percent NaCl equiv during late quartz growth, though there is evidence in one sample for higher salinity fluid having been present, up to 30 wt percent NaCI equiv (some inclusions contain daughter minerals of halite and sulfur). The Th values of over 1,000 measurements on late quartz from the ore zones indicate that the mean temperature during that stage ranged from <200°C at Akeshi to about 200°C at Iwato and 230°C at Kasuga. The presence of vapor-rich inclusions, some with Thv similar to Thl, indicate the presence at times of a two-phase fluid in the center of the ore zones, with depths of about 150 to 300 m below the paleowater table. The mineralizing fluid was relatively oxidized (sulfide/ sulfate ratio about 3:1), close to pyrite-alunite coexistence. Under these redox conditions, a pH of 3 and over a temperature range of 200° to 300°C, AuCl2− complexing may dominate over HAu(SH)2 at salinities above about 2 wt percent NaCl. Several conditions are conducive for high sulfidation mineralization to occur: a crystallizing magma exsolves a fluid, with lower pressure conditions favoring metal fractionation from melt to fluid,the exsolved fluid separates into vapor and saline liquid phases due to immiscibility, with the latter being metal rich,the gas-rich (HCl and SO2 + H2S) vapor ascends to the surface, with at least a portion condensed into meteoric water, forming an acid fluid which leaches the host rock to create permeable zones for later mixing, andthe dense, metal-bearing fluid also ascends into this leached zone and precipitates Cu sulfosalts, sulfides, and Au upon mixing with meteoric water. If the saline liquid is not released from its source adjacent to the magma, due to lack of fracturing, or if there is a strong hydraulic gradient caused by high relief, only the vapor-related stage may occur. This will leave leached, barren rock which is characteristic of many eroded volcanic terranes.

"litter used. The advandages derived fran using peat depend greatly on the qualiity of the peat. The absorption capacity of dry peat is best exploited in cowsheds were all the urine is absorbed by the litter. In this case, the amount of peat required is far less than that of either straw or sawdust. In cowsheds with a urine well, the use of peat as litter permits some reduction in the size of the well. The economic advandage of using peat lies in the better utilization of nutrients. At 1984 prices, the saving achieved by retaining the nutrients is about 6 Finnish marks (about 0.9 USD), per cubic meter of peat used. The price of peat liitter is about 20 marks/m3 (3 USD). Additional benefit is derived frcm the soil improvement effect resulting from long-term use, and frcm the lower cost of constructing the building if the urine well can be made smaller or emitted altogether.

Abstract:
Abstract Insulative coatings are prompting significant interest with increasing environmental and safety awareness and sensitivity to energy efficiency. Aerogels are the best thermal insulators in the world. Cabot’s aerogel has a thermal conductivity of 12mW/m-K (compared to still air or PU foam at 26mW/m-K) and is currently being used extensively in day lighting and oil & gas applications. The performance of aerogel is based on the unique pore structure of the particles that is not impacted by size reduction.

Abstract:
In heat exchangers and liquid cooling devices the thermal conductivity of the liquid is an important factor in their design. Recently it has been shown that adding small amounts of nanoparticles to the liquid can significantly increase the thermal conductivity of the fluid [1]. This study investigates the thermal conductivity of diamond nanofluid. The nanofluid is HPLC grade water with 1% by volume diamond nanoparticles that are 5-50 nm in diameter. The thermal conductivity was measured by the transient hot-wire method. In order to verify the experimental measurement, the thermal conductivity

Abstract The main objective of this study is to simulate the dynamic behavior of entrained solid-particles in a pipe flow and its role in the erosion process. A detailed parametric study changing the solid particle diameter, flow rate, pipe diameter, fluid viscosity, and solid particle density was performed to find the critical parameter that affects erosion in a pipeline. To fulfill the objectives of the study, a Computational Fluid Dynamics (CFD) simulation was conducted for water-solid flow within a complex pipeline geometry with rapid alterations in flow directions.

Abstract:
A new absorption cell interfaced with a Bomem DA3.002 Fourier transform spectrometer has recently been put into operation. It is 5 m long and is capable of paths of up to 200 m at temperatures as low as 20 K. Compared to its 3.5m long predecessor,1,2 it gives longer paths, and, more importantly, has a larger optical aperture (f/25 vs. f/55). The result is improved sensitivity and the capability of higher spectral resolution. The enhanced throughput enables much better performance in the difficult "far" infrared region below the cutoff (≈ 1800 cm-1) of the InSb detector.

We have developed a new calibration capability for 200 nm to 400 nm ultraviolet light-emitting diodes (UV LEDs) using a Type D gonio-spectroradiometer. The recently-introduced mean differential continuous pulse (M-DCP) method is used to overcome the measurement difficulty associated with the initial forward voltage, VF, anomaly of a UV LED, which makes it impossible to use VF to infer junction temperature, TJ, during pulsed operation. The new measurement facility was validated indirectly by comparing the measured total luminous flux of a white LED with that measured using the NIST’s 2.5 m abso

Abstract:
Abstract The ability to use supercritical fluids as a heat transfer medium has benefits near the critical point as the specific heat and thermal conductivity approach infinity. However, because of these large thermodynamic property variations estimates for the heat transfer coefficients and wall temperatures can be difficult. With large changes in thermodynamic properties, threedimensional simulations have been used for heat transfer predictions, which can be time-consuming and computationally expensive. To reduce computational expenses, a comparison is made between 2D-axisymmetric and 3D hori

Polythiophene (Pth) is a conducting polymer that can be synthesized electrochemically as aligned nanofiber forests without the need for stretching individual fibers.

Abstract:
Seton Lake is a freshwater fiord located in southwestern British Columbia, roughly 4 km west of Lillooet and 250 km north-northeast of Vancouver. Located in the Coast Mountains, it is an alpine lake about 22-km long and roughly 1-1.5 km wide. It is separated from nearby Anderson Lake, located to the west, by a large pre-historic rock avalanche deposit at Seton Portage. The lake stands at about 243 m above sea level and is up to about 150 m deep (BC gov., 1953). Water level is controlled by a hydroelectric dam (i.e., Seton dam) located at the eastern end of the lake. Here, the lake drains east
