Blossite, A-Cu4+Y|+Or, a New Fumarolic Sublimate from Izalco
American Mineralogist, Volume 72, pages397-400, 1987 Blossite, a-Cu4+Y|+Or,a new fumarolic sublimate from Izalco volcano, El Salvador Paur,D. RonrxsoN Department of Geology, Southern Illinois University, Carbondale,Illinois 62901, U.S.A. JoHN M. Hucnps Department of Geology, Miami University, Oxford, Ohio 45056, U.S.A. MlnyANN L. Mal,rNcoNrco Department of Geology, Southern Illinois University, Carbondale,Illinois 62901, U.S.A. Ansrucr Blossite, a-CurYrOr, occurs as a fumarolic sublimate in the "Y" fumarole of Izalco volcano, El Salvador. The mineral is the natural analogue of the previously described synthetic phase, and is the the low-temperature polymorph of ziesite, 0-CurV'O', which was discoveredat the same site. The crystalsare orthorhombic, Fdd2, :u/rtha : 20.676(6), b:8.392(3), and c : 6.446(2)A. ttre crystal structurewas refined to R : 0.047. The atomic arrangementconsists of (100) planes of (VrOr)o- anionic groups; adjacent planes along [00] are linked by Cu2* in fivefold coordination. On the basis of previously deter- mined atomic arrangements,the a-B (blossite-ziesite)phase transition is of the non-near- est-neighborreconstructive type. Blossite occursas a equant, black anhedral crystalsup to 150 rrm in greatestdimension. The mineral has a metallic luster and a red-brown streak. The calculateddensity (Z: 8) is 4.05 I g/cm3. Blossite is opaque, and white in blue-filtered white light in air, with weak to moderate bireflectancein shadesof creamy-white, and a moderate anisotropy, from gray to creamy brown-gray. Minimum and maximum reflectancevalues (in air) are 481 nm, 14.6,15.3o/o;547 nm, 15.4,16.60/o;591 nm, 14.8,16.70/o, and,644 nm, 14.5,15.7o/o. -
Combinatorial Synthesis and High-Throughput Characterization of Multinary Vanadate Thin-Film Materials Libraries for Solar Water Splitting’ Supervisors: Prof
Combinatorial Synthesis and High- Throughput Characterization of Multinary Vanadate Thin-Film Materials Libraries for Solar Water Splitting Dissertation zur Erlangung des Grades Doktor-Ingenieurin der Fakultät für Maschinenbau der Ruhr-Universität Bochum von Swati Kumari aus Begusarai, India Bochum 2020 The presented work was carried out from August 2016 to April 2020 at the chair of Materials Discovery and Interfaces (MDI) under the supervision of Prof. Dr.-Ing. Alfred Ludwig in the Institute for Materials, Department of Mechanical Engineering, Ruhr-Universität Bochum, Germany. Dissertation eingereicht am: 21.04.2020 Tag der mündlichen Prüfung: 27.05.2020 Vorsitz: Prof. Dr.-Ing. Andreas Kilzer Erstgutachter: Prof. Dr.-Ing. Alfred Ludwig Zweitgutachter: Prof. Dr. rer. nat. Wolfgang Schuhmann “Child-like curiosity – seeking, questioning, and understanding – is the basis of knowledge that opens up new avenues that we call progress.” – Klaus von Klitzing – Abstract Solar water splitting using a photoelectrochemical cell (PEC) is an attractive route for the generation of clean and renewable fuels. PEC cell converts solar energy into an intermediate chemical energy carrier such as molecular hydrogen and oxygen. The solar-driven oxygen evolution at photoanode is limited due to the lack of materials with suitable optical, electronic properties, and operational stability. In this thesis, combinatorial synthesis and high- throughput characterization methods were used to investigate the suitability of multinary vanadium-based material systems for PEC application. Multinary ternary (M-V-O) and quaternary (M1-M2-V-O) metal vanadium oxide photoanodes: Fe-V-O, Cu-V-O, Ag-V-O, W-V-O, Cr-V-O, Co-V-O, Cu-Fe-V-O, and Ti-Fe-V-O materials libraries were synthesized using combinatorial reactive magnetron sputtering with a continuous composition and thickness gradients. -
CRYSTAL STRUCTURE of Γ-Cu2v2o7 and ITS
671 The Canadian Mineralogist Vol. 43, pp. 671-677 (2005) CRYSTAL STRUCTURE OF ␥-Cu2V2O7 AND ITS COMPARISON TO BLOSSITE (␣-Cu2V2O7) AND ZIESITE (-Cu2V2O7) SERGEY V. KRIVOVICHEV§, STANISLAV K. FILATOV AND PAVEL N. CHEREPANSKY Department of Crystallography, St.Petersburg State University, University Emb. 7/9, RU-199034 St. Petersburg, Russia THOMAS ARMBRUSTER Laboratorium für chemische and mineralogische Kristallographie, Universität Bern, Freiestrasse 3, CH–3102 Bern, Switzerland OLGA YU. PANKRATOVA Department of Inorganic Chemistry, St.Petersburg State University, University Emb. 7/9, RU-199034 St. Petersburg, Russia ABSTRACT Single crystals of ␥-Cu2V2O7 were obtained by the method of chemical transport reactions. The crystal structure [triclinic, P¯1, a 5.0873(10), b 5.8233(11), c 9.4020(18) Å, ␣ 99.780(3),  97.253(3), ␥ 97.202(3)°, V 269.20(9) Å3, Z = 2] has been solved by direct methods and refined to R1 = 0.021 (wR2 = 0.049) using 949 unique observed reflections with |Fo| ≥ 4F. The atomic arrangement contains two symmetrically independent Cu2+ cations. The Cu(1) site is coordinated by six O atoms to form a distorted Cu(1)O6 octahedron, whereas the Cu(2) site is coordinated by five O atoms arranged at the vertices of an elongate 5+ Cu(2)O5 square pyramid. Two symmetrically independent V cations are tetrahedrally coordinated by four O atoms each. The O(5) atom bridges the V(1)O4 and V(2)O4 tetrahedra. The Cu(1)O6 octahedra and Cu(2)O5 square pyramids form two types of chains running parallel to the a axis. The chains are linked by V2O7 groups into a complex heteropolyhedral framework. -

COPPER-BASED TERNARY OXIDE SEMICONDUCTORS for SOLAR ENERGY CONVERSION and ENVIRONMENTAL REMEDIATION by MOHAMMAD KABIR HOSSAIN DI
COPPER-BASED TERNARY OXIDE SEMICONDUCTORS FOR SOLAR ENERGY CONVERSION AND ENVIRONMENTAL REMEDIATION by MOHAMMAD KABIR HOSSAIN DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at The University of Texas at Arlington August, 2019 Arlington, TX Supervising committee: Krishnan Rajeshwar, Supervising Professor Robin T. Macaluso Daniel W. Armstrong Peter Kroll Copyright by Mohammad Kabir Hossain 2019 All Rights Reserved ii To the memories of my Late Mother iii ACKNOWLEDGMENTS During the past five years of my life as a graduate student, I had remarkable opportunities to work and crossed paths with certain individuals whose relentless support and motivations had been my core source of courage. I have always lacked adequate verbose hence failed to express how immensely I have enjoyed their companionship, guidance and keen help in every aspect of my PhD journey. Therefore, this acknowledgment section is the most satisfying part that I was looking forward to writing to appreciate and be grateful for the enormous support I received throughout this time. First and foremost, I would like to thank God for blessing me with the requisite strength that I needed to survive this chapter of my life. Then at the top of my prodigious list of people, I am truly thankful to my advisor, Dr Krishnan Rajeshwar. I am forever indebted to him for all his contributions of time, mentorship and motivations during these years. Not only he provided a suitable research environment to perform my graduate studies but, most importantly, he made sure that I take my work seriously. I sincerely appreciate the fact that he always made room for my research interests and he ensured his adequate assistance at pivotal moments in my work.
