Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

The invention provides the switching of magnetic properties in isolated (magnetically non–interacting) molecules in solution. Switching from the diamagnetic to the paramagnetic state is performed by irradiation with blue‐green light (500 nm), and the conversion back to the diamagnetic form is induced with blue‐violet light (435 nm). The process is fully reversible. No fatigue or degradation is observed after several thousand cycles at room temperature under air. In spite of the extremely high photosensitivity, the thermal conversion of the high energy paramagnetic state to the diamagnetic ground state is very slow (t1/2 at 54°C: 27 hours).
The invention can be used as optical storage media, switchable contrast agent for magnetic resonance imaging (dynamic MRI) and for contact free manipulation of objects.
A new family of layered titanates containing chemically bound unsaturated amine enables the fixation and immobilization of radioactive iodine-129 and iodine-131 from gaseous products of nuclear fission.
A new family of titanates, niobates and tantalates containing chemically bound functional multivalent polyamines enables surface binding of nucleic acids.
Adhesive microstructure of surfaces: anisotropic attraction generated by isotropic –easy to produce- components.
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.
