GFS Chemicals behaves like three chemical companies in one. Our core chemistries fall in three basic disciplines - Organic, Inorganic and Analytical Reagents. We have expertise in each, and are organized as business units to service customers efficiently. We share many common services among disciplines and there is constant communication among them. Membranes, not walls We don’t isolate customer needs. We share support, information technology, and knowledge freely among the divisions. If one division can help another with a solution, walls don’t stand in the way. We have “membranes”, allowing us to collaborate to solve problems. This is a key benefit to working with us.

As an active participant on the ACS Reagents Committee for over 30 years, we have long recognized the importance of providing more than the minimum required. Also, our involvement supporting many industries such as pharmaceutical, electronics and power storage, has given us a global perspective on the transformation of expectations in this area. While the American Chemical Society is close to instituting new test methods for ACS Reagent Grade materials (ACS Reagent Chemicals, 11th Edition), GFS is not only prepared for the change from testing heavy metals using sulfide precipitation represented on “as Pb” (Lead) basis to testing by ICP-OES but has utilized this approach for almost a decade. We perform full ICP scans for more than 60 elements, including heavy metals, for the entire spectrum of grades for many materials. This capability provides feedback on the trace levels of individual constituents, for each item, whether those levels are reported or not. This approach is the cornerstone for producing materials where reproducibility and reporting accuracies are critical to our customers and their applications.

However, because of its radiotoxicity and the subsequent requirement of special facilities and handling procedures for research, only a few studies have been completed, many of which are over 20 years old. In this study, we report the synthesis of pure alkali pertechnetates (sodium, potassium, rubidium, and cesium) and analysis of these compounds by Raman spectroscopy, X-ray absorption spectroscopy (XANES and EXAFS), solid-state nuclear magnetic resonance (static and magic angle spinning), and neutron diffraction. The structures and spectral signatures of these compounds will aid in refining the understanding of 99Tc incorporation into and release from nuclear waste glasses.

Nanostructuring of tungsten composites is expected to dramatically improve the materials’ properties and enhancing the performance in present applications but also enabling totally new possibilities. Nanostructured WC-Co materials have been the focus of researchers and engineers for over two decades. New fabrication methods have been developed. But, the fabrication of true nanograined WC-Co composites is still a challenge. Nanostructured tungsten-based materials for applications as plasma facing materials in fusion reactors have attracted a growing interest. This Thesis summarizes work on the development of chemical methods for the fabrication of two different types of nanostructured tungsten-based materials; WC-Co composites mainly for cutting tools applications and W-ODS materials with yttria particles, intended as plasma facing materials in fusion reactors. The approach has been to prepare powders in two steps: a) synthesis of uniform powder precursors containing ions of tungsten and cobalt or yttrium by precipitation from aqueous solutions and b) processing of the precursors into WC- or W-based nano-composite powders.

Most glymes are usually less volatile and less toxic than common laboratory organic solvents; in this context, they are more environmentally benign solvents. However, it is also important to point out that some glymes could cause long-term reproductive and developmental damage despite their low acute toxicities. Glymes have both hydrophilic and hydrophobic characteristics that common organic solvents lack. In addition, they are usually thermally and chemically stable, and can even form complexes with ions. Therefore, glymes are found in a broad range of laboratory applications including organic synthesis, electrochemistry, biocatalysis, materials, Chemical Vapor Deposition (CVD), etc. In addition, glymes are used in numerous industrial applications, such as cleaning products, inks, adhesives and coatings, Received 6th October 2013 batteries and electronics, absorption refrigeration and heat pumps, as well as pharmaceutical Accepted 9th December 2013 formulations, etc. However, there is a lack of a comprehensive and critical review on this attractive DOI: 10.1039/c3ra47191h subject.

    Perylene Diimide: a Versatile Building Block for Complex Molecular Architectures and a Stable Charge Storage Material

    Perylene Diimide: A Versatile Building Block for Complex Molecular Architectures and a Stable Charge Storage Material Margarita Milton Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2018 © 2018 Margarita Milton All rights reserved ABSTRACT Perylene Diimide: A Versatile Building Block for Complex Molecular Architectures and a Stable Charge Storage Material Margarita Milton Properties such as chemical robustness, potential for synthetic tunability, and superior electron-accepting character describe the chromophore perylene-3,4,9,10-tetracarboxylic diimide (PDI) and have enabled its penetration into organic photovoltaics. The ability to extend what is already a large aromatic core allows for synthesis of graphene ribbon PDI oligomers. Functionalization with polar and ionic groups leads to liquid crystalline phases or immense supramolecular architectures. Significantly, PDI dianions can survive in water for two months with no decomposition, an important property for charge storage materials. We realized the potential of PDI as an efficient negative-side material for Redox Flow Batteries (RFBs). The synthetic tunability of PDI allowed for screening of several derivatives with side chains that enhanced solubility in polar solvents. The optimized molecule, PDI[TFSI]2, dissolved in acetonitrile up to 0.5 M. For the positive-side, we synthesized the ferrocene oil [Fc4] in high yield. The large hydrodynamic radii of PDI[TFSI]2 and [Fc4] preclude their ability to cross a size exclusion membrane, which is a cheap alternative to the typical RFB membranes. We show that this cellulose-based membrane can support high voltages in excess of 3 V and extreme temperatures (−20 to 110 °C).
