CO2Storage Capacity
Authors: Hedley B. J. , Gluyas J. G. 
Published: July 2015

AbstractCapture of carbon dioxide emissions from industry and their subsequent storage deep below the Earth's surface in porous rocks has great potential for reducing the release of greenhouse gases into the atmosphere. Carbon capture and storage (CCS) could provide humankind with a plausible transition to a low carbon economy without having to suddenly stop use of fossil fuels.A prerequisite for geostorage of carbon dioxide is determination of storage capacity, of a potential site, a geological province or indeed for a whole country. The approach to calculation of the resource (available pore space) for carbon dioxide storage shares much in common with the process used to estimate oil, gas, or indeed aquifer water volume. The calculation involves the following stages: measurement of gross rock volume, calculation of net (porous) rock volume, calculation of void space, and finally determination of how much of the void space could be filled with carbon dioxide. The accuracy with which the first three calculations can be made is determined by the quantity and quality of the data available. Typically, gross rock volume is not measured directly but instead combines geographic location data with time domain information from seismic reflection surveys then subject to interpretation of the horizons of interest. Net to gross and porosity tend to be measured very accurately for individual wells or parts of wells but as formation architecture is both heterogeneous and anisotropic, further uncertainties are introduced in the upscaling process from single or multiple wells to field (storage site). However, the most difficult step in the calculation is the final one; what proportion of the void space can be occupied byCO2? Theoretically, the whole of the pore space could be occupied byCO2, but in practice, it will not be possible to remove all of the water or petroleum from a system used for carbon storage. Some of the existing fluids (water or petroleum) will not be displaced.For a regional assessment of storage capacity, here has been a tendency to use an “efficiency factor”—that is a very small number which when applied to the large pore volume calculated gives a plausible storage volume! The calculation may also be subject to numerical simulation in an adaptation of the same approach used by (petroleum) reservoir engineers. Efficiency factors of a small percentage or less are the norm. For an individual, well‐characterized site, it is likely to be possible to fill a much greater portion of the pore space. Observations inCO2‐enhanced oil recovery (EOR) projects have indicated that it may be possible to displace 40% or more of the pore fluids. Indeed, it is the potential for enhanced oil (and gas) recovery which may drive our understanding of the displacement process. EOR projects are more likely to get funded in the short term because they generate a revenue stream.In addition to storage ofCO2in conventional reservoirs, options exist for storage and/or sequestration in unconventional reservoir systems (shales, coals, and fractured basement rocks).

Published: July 2015

AbstractThe first highly diastereo‐ and enantioselective multicomponent reaction of diazooxindoles, nitrosoarenes, and nitroalkenes using a newly developed hydrogen‐bond catalyst has been successfully developed for the efficient construction of a series of spirooxindole derivatives with excellent functional‐group tolerance. Spirooxindoles are formed in excellent yields and stereoselectivities, and the method represents an unprecedented approach for trapping the active intermediate with a nitroalkene to form biologically important compounds having three contiguous stereogenic centers with excellent asymmetric induction.

AbstractHuman mesenchymal stem/stromal cells (MSC) are promising candidates for cell‐based therapies and the development of microcarrier‐based cultures in scalable bioreactors with well‐defined xenogeneic‐free components represent important milestones towards the clinical‐scale production of these cells. In this work, we optimized our previously developed xeno‐free microcarrier‐based system for the scalable expansion of human MSC isolated from bone marrow (BM MSC) and adipose‐derived stem/stromal cells (ASC). By adapting the agitation/feeding protocol at the initial cell seeding/cultivation stage in spinner flasks, we were able to maximize cell expansion rate and final cell yield. Maximal cell densities of 3.6 × 105 and 1.9 × 105 cells/mL were obtained for BM MSC (0.60 ± 0.04 day–1) and ASC (0.9 ± 0.1 day–1) cultures, upon seven and eight days of cultivation, respectively. Ready‐to‐use microcarriers Synthemax® II and Enhanced Attachment® supported identical expansion performance of BM MSC, turning those effective alternatives to the pre‐coated plastic microcarriers used in our xeno‐free scalable culture system. Importantly, expanded MSC maintained their immunophenotype and multilineage differentiation potential. Moreover, secretome analysis suggested a priming effect of stirred culture conditions on cytokine production by MSC. This culture system yielded considerable final cell densities that can be scaled‐up to controlled large‐scale bioreactors allowing a more efficient, safe and cost‐effective MSC production for clinical settings.

BACKGROUNDEpithelioid inflammatory myofibroblastic sarcoma (E‐IMS) is a recently established rare variant of inflammatory myofibroblastic tumor. It is characterized by a distinctive constellation of clinical, pathological, and molecular features, including a nearly exclusive intraabdominal location, strong male predilection, aggressive clinical course, predominance of epithelioid tumor cells, and Ran‐binding protein 2 (RANBP2)‐anaplastic lymphoma kinase (ALK) fusion in the majority of cases. To the authors’ knowledge, the cytologic features of E‐IMS have not been described to date.METHODSCases of E‐IMS that had corresponding cytology were searched. Six cytology samples (1 fine‐needle aspiration sample, 2 imprint samples, and 3 effusion fluids) containing tumor cells were identified in 5 patients with E‐IMS.RESULTSThe cytomorphology included large monotonous epithelioid cells arranged in loose aggregates or singly, with admixed myxoid stroma, and an inflammatory background rich in neutrophils. The tumor cells had a large, round, eccentric nucleus with vesicular chromatin, prominent nucleoli, and moderate amounts of pale cytoplasm. Delicate thin‐walled branching vessels traversing tumor aggregates was a prominent feature in a fine‐needle aspiration sample. Immunohistochemically, ALK was positive in all 5 tumors, with a nuclear membranous staining pattern noted in 3 cases and a cytoplasmic pattern observed in the other 2 cases. ALK rearrangement was confirmed in all 5 tumors by molecular genetic studies.CONCLUSIONSThe cytologic features of E‐IMS recapitulate its histologic characteristics. E‐IMS merits inclusion in the differential diagnosis of any intraabdominal, large epithelioid cell neoplasm. Confirmation of ALK rearrangement is advisable because patients may benefit from targeted therapies. Cancer (Cancer Cytopathol) 2015;123:495–504. © 2015 American Cancer Society.
Experience‐related reorganization of giant synapses in the lateral complex: Potential role in plasticity of the sky‐compass pathway in the desert ant Cataglyphis fortis
Authors: Schmitt Franziska , Stieb Sara Mae , Wehner Rüdiger , Rössler Wolfgang 
Published: July 2015

ABSTRACTCataglyphis desert ants undergo an age‐related polyethism from interior workers to relatively short‐lived foragers with remarkable visual navigation capabilities, predominantly achieved by path integration using a polarized skylight‐based sun compass and a stride‐integrating odometer. Behavioral and physiological experiments revealed that the polarization (POL) pattern is processed via specialized UV‐photoreceptors in the dorsal rim area of the compound eye and POL sensitive optic lobe neurons. Further information about the neuronal substrate for processing of POL information in the ant brain has remained elusive. This work focuses on the lateral complex (LX), known as an important relay station in the insect sky‐compass pathway. Neuroanatomical results in Cataglyphis fortis show that LX giant synapses (GS) connect large presynaptic terminals from anterior optic tubercle neurons with postsynaptic GABAergic profiles of tangential neurons innervating the ellipsoid body of the central complex. At the ultrastructural level, the cup‐shaped presynaptic structures comprise many active zones contacting numerous small postsynaptic profiles. Three‐dimensional quantification demonstrated a significantly higher number of GS (∼13%) in foragers compared with interior workers. Light exposure, as opposed to age, was necessary and sufficient to trigger a similar increase in GS numbers. Furthermore, the increase in GS numbers was sensitive to the exclusion of UV light. As previous experiments have demonstrated the importance of the UV spectrum for sky‐compass navigation in Cataglyphis, we conclude that plasticity in LX GS may reflect processes involved in the initial calibration of sky‐compass neuronal circuits during orientation walks preceding active foraging. © 2015 Wiley Periodicals, Inc.

Mercury Complexes with Tripodal Pseudopeptides Derived from D‐Penicillamine Favour a HgS3 Coordination
Authors: Jullien Anne‐Solène , Gateau Christelle , Lebrun Colette , Delangle Pascale 
Published: July 2015

AbstractThe pseudopeptides L4 and L5 are built on a nitrilotriacetic scaffold and functionalized with three D‐penicillamine (D‐Pen) units. D‐Pen is an interesting building block and a bulkier analogue of cysteine with the β‐methylene hydrogen atoms replaced by larger methyl groups. The two sulfur ligands L4 and L5 are studied here with the toxic HgII ion. The formation of the two mononuclear complexes HgL4 and HgL5 is demonstrated by 1H NMR spectroscopy and mass spectrometry and the tristhiolato coordination is unambiguously evidenced by the UV absorption signatures. An important feature is the stabilization of the HgS3 coordination mode at the expense of the generally preferred HgS2 linear coordination. It appears that the hindered D‐Pen pseudopeptide L5 is capable of stabilizing the unusual HgS3 coordination over a large pH range in water, pH > 5.5. This water‐soluble compound can therefore be considered as a promising chelating agent for mercury detoxification.
Measurement of Mechanical Strength of Glass‐to‐Metal Joints
Authors: Selçuk A. , Atkinson A. 
Published: July 2015

AbstractThree different test geometries were used to apply shear loading to fracture glass‐to‐metal joints typical of seals intended for use in planar solid oxide fuel cells (SOFCs): asymmetric compression; symmetric compression; and four‐point asymmetric bending. The measured apparent shear strengths were found to differ by an order of magnitude depending on the test configuration employed. In particular, the apparent shear strength measured in the asymmetric compression test was very low. Conversely, the highest apparent shear strengths were measured using the symmetric compression test and the four‐point asymmetric bend test gave an intermediate result. It is shown, by finite element modelling, that these differences are caused by differences in the normal stresses transverse to the joint. The locus of failure was always along the glass/metal interface in all test geometries. It is concluded that mechanical test procedures used to characterize glass‐ceramic seals in SOFC stacks need to be selected and interpreted with great care.

Liver surface is covered by a collagenous layer called the Glisson's capsule. The structure of the Glisson's capsule is barely seen in the biopsy samples for histology assessment, thus the changes of the collagen network from the Glisson's capsule during the liver disease progression are not well studied. In this report, we investigated whether non‐linear optical imaging of the Glisson's capsule at liver surface would yield sufficient information to allow quantitative staging of liver fibrosis. In contrast to conventional tissue sections whereby tissues are cut perpendicular to the liver surface and interior information from the liver biopsy samples were used, we have established a capsule index based on significant parameters extracted from the second harmonic generation (SHG) microscopy images of capsule collagen from anterior surface of rat livers. Thioacetamide (TAA) induced liver fibrosis animal models was used in this study. The capsule index is capable of differentiating different fibrosis stages, with area under receiver operating characteristics curve (AUC) up to 0.91, making it possible to quantitatively stage liver fibrosis via liver surface imaging potentially with endomicroscopy.
