Solid-state electrochemical synthesis of ammonia: a review
Journal of Solid State Electrochemistry, 2011Ammonia is one of the most produced chemicals worldwide, and it is not only a major end product but also an important energy storage intermediate. The solid-state electrochemical synthesis of ammonia has the promise to overcome the limitations of the conventional catalytic reactors such as the limited conversion, severe environmental pollution and high

Rapid Solid-State Precursor Synthesis of Materials
Science, 1992Precursor reactions based on metathetical (exchange) pathways have been found to be an effective synthetic route for the preparation of a large number of materials. These solid-solid reactions are extremely rapid (typically less than 1 second) and often can be initiated at or near room temperature.

Exploratory Synthesis in the Solid State. Endless Wonders
Inorganic Chemistry, 2000This article gives an overview of recent developments in three areas of solid state chemistry: (1) The discovery that centered and originally-adventitious interstitial elements Z are essential for the stability of M6X12-type cluster halides of group 3 and 4 metals has led to a large amount of new chemistry through tuning structures and compositions of ...

Solid state synthesis of Bi2Sr2CaCu2Ox superconductor
Materials Research Bulletin, 1991Abstract The high-temperature superconducting material Bi 2 Sr 2 CaCu 2 O x (2212) was synthesized by reaction of oxides and carbonates. Several stoichiometries and a range of temperatures and oxygen partial pressures were investigated for the production of pure 2212.

Solventothermal Synthesis of Solid‐State Chalcogenidometalates
Angewandte Chemie International Edition in English, 1997AbstractDevelopment of solventothermal methods in the intermediate‐temperature (100–600°C) range has been motivated by current interest in the design of solid‐state compounds with open framework structures. The preparation of nanoporous chalcogenidometalates by this technique is particularly promising, as a combination of the typical ion‐exchanging and

The Emerging Art of Solid-State Synthesis
Science, 1995Solid-state chemists are exploring new routes to synthesizing useful compounds, including self-assembly, by which complex structures form spontaneously from simpler ones. Parkinson provides background and comment on a research report by Noh et al . in this issue ( p.

Solid‐state synthesis of a ladder polymer
Journal of Polymer Science: Polymer Chemistry Edition, 1979AbstractSolid‐state synthesis of a cyclically bound ladder polymer from a cyclic tetradiyne (cyclodotriaconta‐1,3,9,11,17,19,25,27‐octayne) is described. Irradiation of the colorless, needlelike monomer crystals with interstitially incorporated chloroform with 50 Mrad of 60Co γ‐ray radiation results in red‐brown polymer fibers in nearly quantitative ...
