Introduction/Motivation The most fascinating aspect of nature is surely its multiplicity and, through evolution, its capacity to adapt to current necessities. Similarly, humankind has adapted and, with a bit of ingenuity, has revolutionized its everyday life in the name of progress. In this (re)evolution, materials have surely fulfilled a key role, so much that key steps of human development have been denoted with material names (age of stone, bronze, iron, etc.). However, while earliest craftsmen based their processes on the “trial and error” approach, nowadays new materials are prepared with awareness and, thanks to technology, enhanced control over the whole process. This way, the attention can be more and more focused toward complex materials (ternary and quaternary systems, smart materials, composites, etc.), in some cases taking again inspiration from nature (biomimetic approach). One important contribution in the search for new materials is surely the discovery of the nano-world. In this realm, properties are sensible to size and morphology, so that each nano-system can be considered as a potential new material. Potentiality of nano-sized materials has been largely proved, and a massive part of both fundamental and applied research is today devoted to the study and field of applications of these materials. It will be sufficient to go to Web of KnowledgeSM and type “nano*” to find more than 1 Million1 entries concerning related publications, about 130.000 only in 2012. However, a closer look will show that a significant percentage of this research is related to oxides and metals (over 40.000 entries), while the number drastically drops when searching for other systems, such as metallic ceramics (namely transition metal nitrides and metal carbides), which display less than 100 entries (2012). These numbers have to be considered just as a rough estimation of course, but can still give an idea about the worldwide predilection for some classes of materials over others. Specifically for metallic ceramics, the lack of publications does not reflect their potential but rather the difficulties related to their synthesis as dense (compact) and defect-free structures, fundamental prerequisites for advanced mechanical applications. However, potentialities of these materials go far beyond engineering purposes. As suggested by their name, metallic ceramics possess an intriguing combination of properties that place them between high performance ceramics and pure metals. The number of 1 This number does not contain medical, biomedical, geological and environmental entries. 1/191 Introduction Chapter 1 envisaged applications can then be very broad and can even be broadened going to the nanoscale (e.g. higher surface area, tailored properties via size-control, easier shaping and processing, quantum effects, etc.). In simpler words, there is more than just tougher cutting tools to be discovered. One steady step, however, must be overcome: the necessity to simplify their production to make these systems readily available, in reasonable amounts, both for better investigation and easier testing/processing. The present habilitation work aims to close the gap between preparation and processing, indicating novel synthetic pathways for an easier, unexpansive, and sustainable synthesis of transition metal nitride and carbide based nanostructures and easier processing thereafter. In particular, aiming at expanding the coverage of ceramic materials in applied science, several key-points are encompassed in the present work, for instance the influence of the starting materials was carefully studied, also using complex precursors (e.g. biopolymers), to gain control over composition, size and morphology. In this way, hierarchical structures (such as fibres, mesoporous materials, replica of bio-objects etc.) could also be obtained. The presented routes are, concept-wise, similar, and they all start by building up a

  • Theoretical Calculations on the Structural, Electronic and Optical
    Theoretical calculations on the structural, electronic and optical properties of bulk silver nitrides Mohammed S. H. Suleiman1,2, ∗ and Daniel P. Joubert1, † 1School of Physics, University of the Witwatersrand, Johannesburg, South Africa. 2Department of Physics, Sudan University of Science and Technology, Khartoum, Sudan. (Dated: January 1, 2013) We present a first-principles investigation of structural, electronic and optical properties of bulk crystalline Ag3N, AgN and AgN2 based on density functional theory (DFT) and many-body pertur- bation theory. The equation of state (EOS), energy-optimized geometries, cohesive and formation energies, and bulk modulus and its pressure derivative of these three stoichiometries in a set of twenty different structures have been studied. Band diagrams and total and orbital-resolved density of states (DOS) of the most stable phases have been carefully examined. Within the random-phase approximation (RPA) to the dielectric tensor, the single-particle spectra of the quasi electrons and quasi holes were obtained via the GW approximation to the self-energy operator, and optical spec- tra were calculated. The results obtained were compared with experiment and with previously performed calculations. CONTENTS published works5.

  • Study on the Formation and the Decomposition of Agn3 and A
    Study on the formation and the decomposition of AgN3 and a hypothetical compound ReN3 by using density functional calculations. G. Soto. Universidad Nacional Autónoma de México, Centro de Nanociencias y Nanotecnología Km 107 carretera Tijuana-Ensenada, Ensenada Baja California, México. Corresponding Author: G. Soto. CNyN-UNAM P.O. Box 439036, San Ysidro, CA 92143-9036, USA Tel: +52+646+1744602, Fax: +52+646+1744603 E-Mail: [email protected] Abstract We present a comparative study between ReN3 and AgN3 by using density functional theory. The ReN3 is a hypothetical compound proposed by us to interpret the Re to Re interplanar spacing of thin films grown by sputtering. Both, the AgN3 as the ReN3, are calculated as positive enthalpy compounds. The enthalpy might give a clue about the spontaneous decomposition of the solid form, but it cannot be interpreted as a restriction of its synthesizability. As from the calculated total-energy, we discuss the route for the formation of AgN3 starting from atomic species in aqueous solution. We propose that their synthesizability is conditioned by the energy of free nitrogen atoms, and the kinetics of reaction. We conclude that the intrinsic stability of a certain atomic arrangement depends only of the equilibrium of atomic forces, and not from the energy value associated with that structure. 1 1. Introduction Predicting new solids based solely on computer calculations is one of the main challenges of materials science. Achieving this would mean a giant step forward as it would save many hours of fruitless efforts. Although there has been significant progress[1], it is still early to sing praises.

Carlson,1 Kayen K. Yau,1 Robert E. Simpson,2 and Michael P. Short1 Abstract The past decade has seen revolutionary advances in three-dimensional (3D) printing and additive manufacturing. However, a technique to create 3D material microstructures of arbitrary complexity has not yet been developed. We present the conceptual design of a 3D material microprinter as a concrete step toward an eventual 3D material nano- printer. Such a device would enable the use of heterogeneous starting materials with printing resolution on the order of tens of nanometers. By combining a pick-and-place particle transfer method with a custom-built laser sintering optical microscope, the core components of the 3D printer are once again reimagined.

  • Prohibited and Restricted Chemical List
    School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.
