Chemically trapped hydrazine

25.08.2014

A great disadvantage in using hydrazine is the problem that hydrazine is highly toxic and dangerously unstable, especially in the anhydrous form. The Invention: A new family of hydrazine titanates, called LHT-9 (Layered Hydrazinium Titanate – 9 Å) containing chemically bound hydrazine (hydrazinium ion) intercalated into the interlayer space of the layered titanate dissolving this problem. The LHT-9 can be used as: • Carrier substances (chemical containers) containing chemically bound hydrazine and thus allowing to retrieve hydrazine and its compounds, including as possible sources of hydrazine for direct hydrazine fuel cells • Matrices for carrying out inorganic, organic and bioorganic syntheses. Chemically bound hydrazine is used as active constituent • Ion-exchange materials • Reductive sorbents for recovery of noble metals (Rh, Pd, Pt, Au, Ir, Ag) from different industrial solutions • Reluctant for reduction of U, Pu, Np and Tc in spent nuclear fuel; • Precursors for preparation of composite nano-materials, including TiO2-Se nano-composites for Hg vapor scavenging.

Results reveal how discoveries may be hidden in scientific “blind spots”

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
