Abstract: A target for heavy ion or electron bombardment is contemplated as is a method of its preparation. In that method, a) liquid target solution of a target metal salt dissolved in water is deposited into the bottom of a metal target capsule having an open top, and b) heated within the target capsule to form a crystalline material. Steps a) and b) are repeated until the crystalline material contains a target amount of target salt. The target capsule is then heated until the weight of the target capsule remains constant. To mitigate the formation of salt creep during the preparation, the liquid target solution can contain about 2 to about 20 percent v/v of a C2-C4 polyol, or the inside surface of the target capsule is coated with a hydrophobic film that provides a contact angle with water of about 70 to about 1300 prior to liquid deposition.

Abstract: The systems and compressors for use with flammable refrigerants can include features that can reduce or address the generation of sparks or arcs internal or external to the compressor that could ignite the flammable refrigerant. The systems and compressors can also include features that can reduce or address leakage into or out of the hermetic compressor shell which could create a flammable atmosphere that could be ignited if the flammable atmosphere came into contact with an ignition source.

Abstract: The present invention relates to the field of in vivo determination of enzyme activity. It also allows visualization of organisms, organs, tissues and cells. In particular, the present invention provides a method of in vivo visualization and a composition suitable for in vivo determination and/or visualization of enzyme activity by methods such as Magnetic Resonance Imaging, also called Magnetic Resonance Tomography (MRI or MRT), or Magnetic Particle Imaging (MPI). In particular, the activity of the enzyme lipoprotein lipase affects the signals received and allows conclusions on the lipid metabolism of an organism, an organ system, an organ, a tissue and a cell of interest, This method can be employed, e.g., for diagnosis of cardiac disorders, of tumor prognosis and of disorders of the lipid metabolism. The composition used comprises superparamagnetic iron oxide nanocrystals (SPIO) incorporated in the core of lipid micelles designated nanosomes.
