Structural and electrical properties of ceramic Li-ion conductors based on Li1.3_{1.3}Al0.3_{0.3}Ti1.7_{1.7}(PO4_4)3_3-LiF

The work presents the investigations of Li1.3Al0.3Ti1.7(PO4)3-xLiF Li-ion conducting ceramics with 0 < x < 0.3 by means of X-ray diffractometry (XRD), 7Li, 19F, 27Al and 31P Magic Angle Spinning Nuclear Magnetic Resonance (MAS NMR) spectroscopy, thermogravimetry (TG), scanning electron microscopy (SEM), impedance spectroscopy (IS) and density method. It has been shown that the total ionic conductivity of both as-prepared and ceramic Li1.3Al0.3Ti1.7(PO4)3 is low due to a grain boundary phase exhibiting high electrical resistance. This phase consists mainly of berlinite crystalline phase as well as some amorphous phase containing Al3+ ions. The electrically resistant phases of the grain boundary decompose during sintering with LiF additive. The processes leading to microstructure changes and their effect on the ionic properties of the materials are discussed in the frame of the brick layer model (BLM). The highest total ionic conductivity at room temperature was measured for LATP-0.1LiF ceramic sintered at 800{\deg}C and was equal to {\sigma}tot = 1.1 x 10-4 Scm-1

Impact of Li2.9_{2.9}B0.9_{0.9}S0.1_{0.1}O3.1_{3.1} glass additive on the structure and electrical properties of the LATP-based ceramics

The existing solid electrolytes for lithium ion batteries suffer from low total ionic conductivity, which restricts its usefulness for the lithium-ion battery technology. Among them, the NASICON-based materials, such as Li1.3Al0.3Ti1.7(PO4)3 (LATP) exhibit low total ionic conductivity due to highly resistant grain boundary phase. One of the possible approaches to efficiently enhance their total ionic conductivity is the formation of a composite material. Herein, the Li2.9B0.9S0.1O3.1 glass, called LBSO hereafter, was chosen as an additive material to improve the ionic properties of the ceramic Li1.3Al0.3Ti1.7(PO4)3 base material. The properties of this Li1.3Al0.3Ti1.7(PO4)3-xLi2.9B0.9S0.1O3.1 (0 < x < 0.3) system have been studied by means of high temperature X-ray diffractometry (HTXRD), 7Li, 11B, 27Al and 31P magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR), thermogravimetry (TG), scanning electron microscopy (SEM), impedance spectroscopy (IS) and density methods. We show here that the introduction of the foreign LBSO phase enhances their electric properties. This study reveals several interesting correlations between the apparent density, the microstructure, the composition, the sintering temperature and the ionic conductivity. Moreover, the electrical properties of the composites will be discussed in the terms of the brick-layer model (BLM). The highest value of {\sigma}tot = 1.5 x 10-4 Scm-1 has been obtained for LATP-0.1LBSO material sintered at 800{\deg}C

Properties of LiMnBO3 glasses and nanostructured glass-ceramics

Polycrystalline LiMnBO3 is a promising cathode material for Li-ion batteries. In this work, we investigated the thermal, structural and electrical properties of glassy and nanocrystallized materials having the same chemical composition. The original glass was obtained via a standard meltquenching method. SEM and 7Li solid-state NMR indicate that it contains a mixture of two distinct glassy phases. The results suggest that the electrical conductivity of the glass is dominated by the ionic one. The dc conductivity of initial glass was estimated to be in the order of 10-18 S.cm-1 at room temperature. The thermal nanocrystallization of the glass produces a nanostructured glass-ceramics containing MnBO3 and LiMnBO3 phases. The electric conductivity of this glass-ceramics is increased by 6 orders of magnitude, compared to the starting material at room temperature. Compared to other manganese and borate containing glasses reported in the literature, the conductivity of the nanostructured glass ceramics is higher than that of the previously reported glassy materials. Such improved conductivity stems from the facilitated electronic transport along the grain boundaries

Neurocranial osteology and neuroanatomy of a late Cretaceous Titanosaurian Sauropod from Spain (Ampelosaurus sp.)

Titanosaurians were a flourishing group of sauropod dinosaurs during Cretaceous times. Fossils of titanosaurians have been found on all continents and their remains are abundant in a number of Late Cretaceous sites. Nonetheless, the cranial anatomy of titanosaurians is still very poorly known. The Spanish latest Cretaceous locality of "Lo Hueco" yielded a relatively well preserved, titanosaurian braincase, which shares a number of phylogenetically restricted characters with Ampelosaurus atacis from France such as a flat occipital region. However, it appears to differ from A. atacis in some traits such as the greater degree of dorsoventral compression and the presence of proatlas facets. The specimen is, therefore, provisionally identified as Ampelosaurus sp. It was CT scanned, and 3D renderings of the cranial endocast and inner-ear system were generated. Our investigation highlights that, although titanosaurs were derived sauropods with a successful evolutionary history, they present a remarkably modest level of paleoneurological organization. Compared with the condition in the basal titanosauriform Giraffatitan brancai, the labyrinth of Ampelosaurus sp. shows a reduced morphology. The latter feature is possibly related to a restricted range of head-turning movementsThis is a contribution to the research project CGL2009-12143 (Ministerio de Economía y Competitividad, Madrid), of which FK, who is currently supported by the Ramón y Cajal Program, is Principal Investigator.

A basal lithostrotian titanosaur (Dinosauria: Sauropoda) with a complete skull: Implications for the evolution and paleobiology of titanosauria

We describe Sarmientosaurus musacchioi gen. et sp. nov., a titanosaurian sauropod dinosaur from the Upper Cretaceous (Cenomanian - Turonian) Lower Member of the Bajo Barreal Formation of southern Chubut Province in central Patagonia, Argentina. The holotypic and only known specimen consists of an articulated, virtually complete skull and part of the cranial and middle cervical series. Sarmientosaurus exhibits the following distinctive features that we interpret as autapomorphies: (1) maximum diameter of orbit nearly 40% rostrocaudal length of cranium; (2) complex maxilla - lacrimal articulation, in which the lacrimal clasps the ascending ramus of the maxilla; (3) medial edge of caudal sector of maxillary ascending ramus bordering bony nasal aperture with low but distinct ridge; (4) ´tongue-like´ ventral process of quadratojugal that overlaps quadrate caudally; (5) separate foramina for all three branches of the trigeminal nerve; (6) absence of median venous canal connecting infundibular region to ventral part of brainstem; (7) subvertical premaxillary, procumbent maxillary, and recumbent dentary teeth; (8) cervical vertebrae with ´strut-like´ centroprezygapophyseal laminae; (9) extremely elongate and slender ossified tendon positioned ventrolateral to cervical vertebrae and ribs. The cranial endocast of Sarmientosaurus preserves some of the most complete information obtained to date regarding the brain and sensory systems of sauropods. Phylogenetic analysis recovers the new taxon as a basal member of Lithostrotia, as the most plesiomorphic titanosaurian to be preserved with a complete skull. Sarmientosaurus provides a wealth of new cranial evidence that reaffirms the close relationship of titanosaurs to Brachiosauridae. Moreover, the presence of the relatively derived lithostrotian Tapuiasaurus in Aptian deposits indicates that the new Patagonian genus represents a ´ghost lineage´ with a comparatively plesiomorphic craniodental form, the evolutionary history of which is missing for at least 13 million years of the Cretaceous. The skull anatomy of Sarmientosaurus suggests that multiple titanosaurian species with dissimilar cranial structures coexisted in the early Late Cretaceous of southern South America. Furthermore, the new taxon possesses a number of distinctive morphologies - such as the ossified cervical tendon, extremely pneumatized cervical vertebrae, and a habitually downward- facing snout - that have rarely, if ever, been documented in other titanosaurs, thus broadening our understanding of the anatomical diversity of this remarkable sauropod clade. The latter two features were convergently acquired by at least one penecontemporaneous diplodocoid, and may represent mutual specializations for consuming low-growing vegetation.Fil: Martínez, Rubén Darío.

Gardens of the former Cistercian Abbey of the Virgin Mary and Saint Nicholas in Ląd

Przed kasatą w 1819 r. cysterskie opactwo w Lądzie posiadało trzy zespoły ogrodowe: ogród klasztorny (konwentualny) – zlokalizowany po południowej stronie klasztoru nad kanałem rzeki Warty oraz na wyspie pomiędzy kanałem a korytem rzeki, ogród opacki – założony przy pałacu opackim w 2. poł. XVI w. na stoku po wschodniej stronie klasztoru i kościoła oraz wirydarz z fontanną w środku klasztoru. Po kasacie ogrody te uległy dewastacji, a większa część ogrodu opackiego została przyłączona do powstałego na początku XIX w. folwarku. W 1850 r. kościół i klasztor w Lądzie objęli kapucyni, którzy przeprowadzili renowację całości założenia wraz z rewitalizacją jego ogrodów. Na placu przed kościołem powstał wówczas park. Plan kościoła i klasztoru w Lądzie z około 1865 r. dokumentuje lokalizację ogrodów i parku po zamknięciu klasztoru kapucynów przez rząd carski. Na przełomie XIX i XX w. został rozebrany pałac opata oraz większość zabudowań gospodarczych klasztoru. Salezjanie, którzy przybyli do Lądu w 1921 r., przywrócili części dawnych ogrodów ich pierwotną funkcję. W 2008 r. na zlecenie Salezjańskiej Prowincji św. Wojciecha powstał projekt koncepcyjny rewaloryzacji i zagospodarowania parku i ogrodów przy pocysterskim opactwie w Lądzie nad Wartą. Autorami projektu są Anetta Jarosińska-Krokowska i Janusz Nowiński. Przewiduje on nowe zagospodarowanie oraz rekonstrukcję dawnych i obecnych ogrodów przy klasztorze w Lądzie z przeznaczeniem ich na cele rekreacyjne, edukacyjne i gospodarcze.Before the abolition in 1819 the Cistercian abbey in Ląd had three garden complexes: the monastic garden (conventual) – located on the south side of the monastery by the Warta River canal and on as island between the canal and the river-bed, the abbot’s garden – founded by the abbot’s palace in the second half of the 16th century, on the slope on the east side of monastery and the church, as well as a viridarium with a fountain in the monastic interior. After the abolition these gardens became devastated, while the biggest part of the abbot’s garden was incorporated into a grange which came into being at the beggining of the 19th century. In 1850, the church and the monastery in Ląd were taken over by the Capuchins who carried out a renovation of the whole complex and also a revival of its gardens. In the square in front of the church a park was founded at the time. A plan of the church and monastery in Ląd from about 1865 documents the location of the gardens and park after the abolition of the Capuchines’s monastery by the Tsarist government. At the turn of the 19th and 20th centuries, the abbot’s palace was pulled down as well as most of the monastic farm buildings. The Salesians, who came to Ląd in 1921, restored parts of the old gardens to their primary function. In 2008, due to the commission of the Administration of the Salesian Society Facilities of St. Adal bert Inspectorate there came into existence a conceptional project of revalorization and management of the park and gardens by the post-Cisterican abbey in Ląd by the Warta River. The authors of the project are Anetta Jarosińska-Krokowska and Janusz Nowiński. The project anticipates a new management and reconstruction of the old and present gardens by the monastery in Ląd assigning them for purposes of recreation, education and economic ones

Lapides vivi, Deus est lux, ecclesia est paradisus – the Cistercian church in the Middle Ages as a carrier of symbolic meanings

Kościół cystersów, ukształtowany w początkowym okresie formowania zakonu, z prostymi rozwiązaniami architektonicznymi i wyposażeniem, odzwierciedlał cysterską duchowość i liturgię – jego architekturę i wnętrze kształtowała zakonna tradycja i obecne w niej treści duchowe. W oparciu o cysterskie źródła, ze szczególnym wskazaniem na mistyczne treści obecne w nauczaniu św. Bernarda z Clairvaux (zwłaszcza w cyklu jego kazań: In dedicatione ecclesiae), w artykule zostały zaprezentowane znaczenia symboliczne, których wyrazicielem stały się architektura i wyposażenie średniowiecznych świątyń cysterskich. Liturgia sprawowana przez mnichów w tradycji zakonnej cystersów była postrzegana w jedności z liturgią niebiańską, celebrowaną przez aniołów przed tronem Boga. Takie rozumienie liturgii wpłynęło na symboliczną interpretację kościoła klasztornego. Ziemska świątynia, zbudowana z „żywych kamieni” (lapides vivi) – zakonników, którzy ją uświęcają swoją świętością, stanowi mistyczną jedność ze świątynią Boga w niebie i liturgią niebiańską celebrowaną przez aniołów (officium divinum in conspectu Dei et angelorum). Obecność Boga w kościele cysterskim symbolizowało światło słońca, w szczególny sposób obecne w przestrzeni sanctuarium, a kompozycja okien w szczytowej ścianie prezbiterium w symboliczny sposób wyrażała prawdę o jedności i troistości osób Trójcy Świętej. Symbolika świątyni cysterskiej znalazła bogaty wyraz w wystroju i wyposażeniu jej wnętrza interpretowanego jako Raj (ecclesia est Paradisus). Mistyczne i symboliczne znaczenia kościoła klasztornego kształtowały m.in. sens ideowy i ikonografię detalu architektonicznego, monumentalnych krucyfiksów nad przegrodą chóru (arbor vitae), dekoracji stalli (m.in. motyw winnej latorośli) oraz nastaw głównych ołtarzy, ze szczególnym wskazaniem na nastawy typu relikwiarzowego.With its simple architectural solutions and furnishing, a Cistercian church shaped at the early stage of the Order’s formation, conveyed Cistercian spirituality and liturgy, its architecture and interior having been formed by the Order’s tradition and the spiritual contents it entailed. Based on the Cistercian sources, with a particular emphasis on the mystical elements present in the teaching of St Bernard of Clairvaux (especially in his homily series In Dedicatione Ecclesiae), symbolic meanings as expressed in the architecture and furnishing of mediaeval Cistercian churches are analyzed. Liturgy performed by monks in the monastic tradition of the Cistercians was perceived in unity with heavenly liturgy, celebrated by angels before God’s throne. Such understanding of liturgy had an impact on the symbolic interpretation of a monastic church. The earthly Church built of “living stones” (lapides vivi): monks, who sanctified it with their holiness, constituted a mystical unity with God’s Church in Heaven and heavenly liturgy celebrated by angels (officium divinum in conspectu Dei et angelorum). God’s presence in a Cistercian church was symbolized by sunlight, particularly present within the space of the sanctuarium, while the window composition in the presbytery gable wall symbolically expressed the truth of the unity and the Trinitarian character of the persons of the Holy Trinity. The symbolism of a Cistercian church was richly expressed in the décor and furnishing of its interior interpreted as the Paradise (ecclesia est Paradisus). Mystical and symbolic meanings of a monastic church shaped, among others, the ideological and iconographic sense of an architectural detail, monumental crucifixes above the rood screen (arbor vitae), choir stalls’ decoration (e.g. vine motif), as well as high altar retables
