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.

Agile, driven wrist joint with three rotational degrees of freedom: The invention describes a new kind of driven joint, using a specific arrangement of (bevel) gears and motors, which, in combination with a C-shaped rail allow for an energy efficient and accurate usage while having significantly less difficulties with singularities.

Scientists at the University of Göttingen produced different monoclonal antibodies directed against the rat CD88 cell surface receptor, also known as C5aR. C5aR functions as a receptor for the C5a fragment of the complement factor C5. These antibodies can be used to identify C5aR in tissues or cultured cells.

Scientists at the University of Göttingen developed different monoclonal antibodies directed against the human / rat C3a-receptor. C3aR functions as a receptor for the C3a fragment of the complement factor C3, but also binds C4a. C3a binding to the C3a-receptor causes mast cell degranulation (anaphylatoxin).

Background
Using the electroporation process, electrical pulses create pores that allow genetic material to permeate the bacterial membrane of electrocompetent cells. The limiting factor for this standard laboratory method is the efficiency by which DNA can be introduced into E. coli. Commercially available electrocompetent cells are being delivered frozen at about -70 to -80°C. The conventional wisdom is that storage at a higher temperature, for example at -20°C or higher, will result in a significant decrease in viability and transformation efficiency.

Invention

Inventors of Saarland University have established a new method and created a new bacterial strain to generate electrocompetent bacterial cells with a transformation efficiency of up to 5,6 x 1010, which can be handled at room temperature. This electrocompetent cells can be stored at 4°C without losing transformation efficiency. Also the new established protocol is able to improve the transformation efficiencies of commercially available bacterial cells.

The invention can be used for cutting high-strength materials, e. g. during disassembly of nuclear power plants, in under water or offshore applications. Benefits: Immediate start or stop the cutting operation possible; davings of abrasive suspension and time; efficiency improvement.
