Design and Discovery of New Piezoelectric Materials Using Density Functional Theory
DESIGN AND DISCOVERY OF NEW PIEZOELECTRIC MATERIALS USING DENSITY FUNCTIONAL THEORY by Sukriti Manna © Copyright by Sukriti Manna, 2018 All Rights Reserved A thesis submitted to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Mechanical Engineering). Golden, Colorado Date Signed: Sukriti Manna Signed: Dr. Cristian V. Ciobanu Thesis Advisor Signed: Dr. Vladan Stevanovi´c Thesis Advisor Golden, Colorado Date Signed: Dr. John Berger Professor and Head Department of Mechanical Engineering ii ABSTRACT Piezoelectric materials find applications in microelectromechanical systems (MEMS), such as surface acoustic wave (SAW) resonators, radio frequency (RF) filters, resonators, and energy harvesters. Using density functional theory calculations, the present study illus- trates the influence of alloying and co-alloying with different nitrides on piezoelectric and mechanical properties of an existing piezoelectric material such as aluminum nitride (AlN). Besides improving the performance of existing piezoelectric material, a high-throughput screening method is used to discover new piezoelectric materials. AlN has several beneficial properties such as high temperature stability, low dielectric permittivity, high hardness, large stiffness constant, high sound velocity, and complementary metal-oxide-semiconductor (CMOS) compatibility. This makes it widely accepted material in RF and resonant devices. However, it remains a challenge to enhance the piezoelectric modulus of AlN. The first part of this thesis establishes that the piezoelectric modulus of AlN could be improved by alloying with rocksalt transition metal nitrides such as scandium nitride (ScN), yttrium nitride (YN), and chromium nitride (CrN). As the content of the rocksalt end member in the alloy increases, the accompanying structural frustration enables a greater piezoelectric response. -

Geochemical Alteration of Pyrochlore Group Minerals: Pyrochlore Subgroup
American Mineralogist, Volume 80, pages 732-743, 1995 Geochemical alteration of pyrochlore group minerals: Pyrochlore subgroup GREGORY R. LUMPKIN Advanced Materials Program, Australian Nuclear Science and Technology Organization, Menai 2234, New South Wales, Australia RODNEY C. EWING Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico 87131, U.S.A. ABSTRACT Primary alteration of uranpyrochlore from granitic pegmatites is characterized by the substitutions ADYD-+ ACaYO, ANaYF -+ ACaYO, and ANaYOI-I --+ ACaYO. Alteration oc- curred at ""450-650 °C and 2-4 kbar with fluid-phase compositions characterized by relatively low aNa+,high aeaH, and high pH. In contrast, primary alteration of pyrochlore from nepheline syenites and carbonatites follows a different tre:nd represented by the sub- stitutions ANaYF -+ ADYD and ACaYO -+ ADYD. In carbonatites, primary alteration of pyrochlore probably took place during and after replacement of diopside + forsterite + calcite by tremolite + dolomite :t ankerite at ""300-550 °C and 0-2 kbar under conditions of relatively low aHF, low aNa+,low aeaH, low pH, and elevated activities of Fe and Sr. Microscopic observations suggest that some altered pyrochlor1es are transitional between primary and secondary alteration. Alteration paths for these specimens scatter around the trend ANaYF -+ ADYD. Alteration probably occurred at 200-350 °C in the presence of a fluid phase similar in composition to the fluid present during primary alteration but with elevated activities of Ba and REEs. Mineral reactions in the system Na-Ca-Fe-Nb-O-H indicate that replacement of pyrochlore by fersmite and columbite occurred at similar conditions with fluid conpositions having relatively low aNa+,moderate aeaH, and mod- erate to high aFeH.Secondary alteration « 150 °C) is charactlerized by the substitutions ANaYF -+ ADYD,ACaYO -+ ADYD,and ACaXO -+ ADXDtogether with moderate to extreme hydration (10-15 wt% H20 or 2-3 molecules per formula unit). -

Analysis of the Thermal Behaviour of CL-20, Potassium Perchlorate, Lithium Perchlorate and Their Admixtures by DSC and TG

Mater. 2018, 15(1): 115-130; DOI: 10.22211/cejem/78089 Analysis of the Thermal Behaviour of CL-20, Potassium Perchlorate, Lithium Perchlorate and Their Admixtures by DSC and TG Jing-yuan Zhang, Xue-yong Guo,* Qing-jie Jiao, Hong-lei Zhang, Hang Li State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China * E-mail: [email protected] Abstract: The thermal decomposition characteristics of CL-20, potassium perchlorate (KP), lithium perchlorate (LP), a CL-20/KP mixture, and a CL-20/LP mixture were studied using thermogravimetry-differential scanning calorimetry (TG-DSC). The DSC curves for KP exhibited three endothermic peaks and one exothermic peak. The first two endothermic peaks correspond to the rhombic- cubic transition and the fusion of KP, respectively, the third indicates the fusion of KCl, while the exothermic peak is attributed to the decomposition of KP. The DSC curves obtained from LP showed four endothermic peaks and one exothermic peak. The first two endothermic peaks indicate the loss of adsorbed water and water of crystallization, while the third and fourth are associated with the fusion of LP and LiCl, respectively; the exothermic peak is due to the decomposition of LP. The presence of KP had little effect on the thermal decomposition of CL-20 while the addition of LP increased the temperature at which CL-20 exhibits an exothermic peak. In addition, the thermal decomposition of LP appeared to be catalyzed by the presence of CL-20. -

Session 1 Sources and Availability of Materials for Lithium Batteries
Session 1: Sources and Availability of Materials for Lithium Batteries Session 1 Sources and Availability of Materials for Lithium Batteries Adrian Griffin Managing Director, Lithium Australia NL ABSTRACT Lithium, as a feedstock for the battery industry, originates from two primary sources: hard-rock (generally spodumene and petalite), and brines. Brine processing results in the direct production of lithium chemicals, whereas the output from hard-rock production is tradeable mineral concentrates that require downstream processing prior to delivery, as refined chemicals, into the battery market. The processors of the concentrates, the 'converters', are the major constraint in a supply chain blessed with abundant mineral feed. The battery industry must overcome the constraints imposed by the converters, and this can be achieved through the application of the Sileach™ process, which produces lithium chemicals from concentrates direct, without the need for roasting. The cathode chemistries of the most efficient lithium batteries have a common thread – a high dependence on cobalt. Battery manufacturers consume around 40% of the current production of cobalt, a by-product of the nickel and copper industries. This means cobalt is at a tipping point – production will not keep up with demand. In the short term, the solution lies in developing alternative cathode compositions, while in the longer term recycling may be the answer. Lithium Australia NL is researching the application of its Sileach™ process to waste batteries to achieve a high-grade, low-cost source of battery materials and, in so doing, ease the supply constraints on cathode metals. To ensure that the battery industry is sustainable, better utilisation of mineral resources, more efficient processing technology, an active battery reprocessing capacity and less reliance on cobalt as a cathode material are all necessary. -
