Academic Editor: Anna H. Kaksonen Received: 8 January 2015 / Accepted: 27 March 2015 / Published: 2 April 2015 Abstract: In the present study, the feasibility to use phosphate solubilizing bacteria (PSB) to develop a biological leaching process of rare earth elements (REE) from monazite-bearing ore was determined. To predict the REE leaching capacity of bacteria, the phosphate solubilizing abilities of 10 species of PSB were determined by halo zone formation on Reyes minimal agar media supplemented with bromo cresol green together with a phosphate solubilization test in Reyes minimal liquid media as the screening studies. Calcium phosphate was used as a model mineral phosphate. Among the test PSB strains, Pseudomonas fluorescens, P. putida, P. rhizosphaerae, Mesorhizobium ciceri, Bacillus megaterium, and Acetobacter aceti formed halo zones, with the zone of A. -

Some Uses of Mischmetall in Organic Synthesis
REVIEW 9 Mischmetall in organic synthesis Organic synthesis Organic synthesis New from Acros Organics Marie-Isabelle Lannou, Florence Hélion and Jean-Louis Namy Laboratoire de Catalyse Moléculaire, associé au CNRS, ICMO, Bat 420, Université de Paris-Sud, 91405, Orsay, France Some uses of mischmetall in organic synthesis ∗ Marie-Isabelle Lannou, Florence Hélion and Jean-Louis Namy Laboratoire de Catalyse Moléculaire, associé au CNRS, ICMO, Bat 420, Université Paris-Sud, 91405, Orsay, France. Abstract: Mischmetall, an alloy of the light lanthanides, has been used in a variety of organic reactions, either as a coreductant in samarium(II)-mediated reactions (Barbier and Grignard-type reactions, pinacolic coupling reactions) or as the promoter of Reformatsky-type reactions. It has been also employed as the starting material for easy syntheses of lanthanide trihalides, the reactivity of which has been explored in Imamoto and Luche-Fukuzawa reactions and in Mukaiyama aldol reactions. Keywords: mischmetall, samarium, lanthanide, catalysis, organic reactions Introduction The use of rare earth compounds in organic chemistry has grown considerably during the past twenty years. Mainly samarium, cerium, lanthanum, ytterbium, neodymium, dysprosium, lutetium, scandium and yttrium metals and derivatives have been studied. These elements clearly differ in terms of reactivity. For instance, samarium(II) compounds can be used as powerful reductants whereas cerium(IV) ones are strong oxidants, some scandium and ytterbium(III) derivatives are very efficient catalysts in a variety of reactions and chemistry of lanthanum metal shows special features. We thought however that in many reactions, a mixture of lanthanide could be used instead of individual element without significant change in results. -

US Nuclear Cooperation with India
U.S. Nuclear Cooperation with India: Issues for Congress Paul K. Kerr Analyst in Nonproliferation June 26, 2012 Congressional Research Service 7-5700 www.crs.gov RL33016 CRS Report for Congress Prepared for Members and Committees of Congress U.S. Nuclear Cooperation with India: Issues for Congress Summary India, which has not signed the Nuclear Nonproliferation Treaty and does not have International Atomic Energy Agency safeguards on all of its nuclear material, exploded a “peaceful” nuclear device in 1974, convincing the world of the need for greater restrictions on nuclear trade. The United States created the Nuclear Suppliers Group (NSG) as a direct response to India’s test, halted nuclear exports to India a few years later, and worked to convince other states to do the same. India tested nuclear weapons again in 1998. However, President Bush announced July 18, 2005, he would “work to achieve full civil nuclear energy cooperation with India” and would “also seek agreement from Congress to adjust U.S. laws and policies,” in the context of a broader partnership with India. U.S. nuclear cooperation with other countries is governed by the Atomic Energy Act (AEA) of 1954 (P.L. 95-242). However, P.L. 109-401, which President Bush signed into law on December 18, 2006, allows the President to waive several provisions of the AEA. On September 10, 2008, President Bush submitted to Congress, in addition to other required documents, a written determination that P.L. 109-401’s requirements for U.S. nuclear cooperation with India to proceed had been met. President Bush signed P.L. -
Industrial Visit to Nuclear Fuel Complex, Hyderabad on 27Th
INDUSTRIAL VISIT VISITED INDUSTRY:NFC(NUCLEAR FUEL COMPLEX) LOCATION OF THE INDUSTRY:NFC INDUSTRY, ECIL, Moula ali, Hyderabad, Telangana :500062 DATE OF INDUSTRY VISIT:13-02-2019 DEPARTMENT:CHEMICAL ENGINEERING YEAR:ENGINEERING 3rd YEAR CONTENTS: Introduction History Principle of production Flowchart How energy is generated Making of nuclear fuel Oath of thanks INTRODUCTION: The nuclear fuel complex(NFC) was established in 1971 as a major industrial unit of Indian’s department of atomic energy,for the supply of nuclear fuel bundles and reactor core components. It is a unique facility where natural and enriched fuel, zirconium alloy cladding and reactor core components are manufactured under one roof. HISTORY: NFC is a unit of department of atomic energy,Government of India. The complex is responsible for the supply of nuclear bundles and reactor core components for all the nuclear power reactors in India. It is a unique facility where the natural and enriched uranium fuel, zirconium alloy cladding and reactor core components are manufactured under one roof starting from the raw materials. PRINCIPLE OF PRODUCTION: As the power generated is low,then the per capita energy consumption is becoming low. There is insufficient power supply for all the people. Power generated Per capita energy consumption= Total population. since power generated by coal,thermal,tidal,solar energy is very less and it is inadequate for human usage. So by using nuclear energy they have been manufacturing uranium bundles which are used in generating electricity. PRODUCT: Uranium Bundles RAW MATERIALS: Magnesium di- uranate(MDU) Sand containing Zirconium FLOW CHART: FILTERATION DISSOLUTION SLURRY EXTRACTION PRECIPITATION COMPACTION STABILIZATION REDUCTION CALCINATION DRYING PELLET GRINDING PELLET READING SINTERING ENDCAP-WELDING NUCLEAR REACTOR INSPECTION END PLATE WELDING BUNDLE ASSEMBLY These are steps involved in the manufacturing of uranium rods which are used for the electricity generation. -

134 RARE EARTHS1 [Data in metric tons of rare-earth oxide (REO) equivalent content unless otherwise noted] Domestic Production and Use: Rare earths were mined for part of the year by one company in 2015. Bastnäsite, a fluorocarbonate mineral, was mined and processed into concentrates and rare-earth compounds at Mountain Pass, CA. The United States continued to be a net importer of rare-earth products in 2015. The estimated value of rare- earth compounds and metals imported by the United States in 2015 was $150 million, a decrease from $191 million imported in 2014.
