Constellations and platoons of small satellites can offer an assortment of benefits over larger, single function spacecraft. The strict mass, volume, and power limitations of small satellites will require unique micro-technologies to help develop efficient propulsion systems for maneuvering. The Free Molecule Micro-Resistojet (FMMR) has been analyzed and tested in this study to determine its ap...

Examining individual molecules at the atomic scale is one of the most challenging problems of modern science. When crystallization of a molecule is difficult or impossible, an X-ray, electron, or positron micro-beam can act as a probe that enables the scientist to determine the structure of a single molecule. However, the beam itself can damage the molecule, in which case the molecule becomes f...

PR81 is a monoclonal antibody that binds with high affinity to MUC1 that over expressed on breast tumors. PR81 is considered a suitable targeting molecule that was radiolabeled using Cu-64 for positron imaging studies. The monoclonal antibody was conjugated with DOTA moiety and after purification was evaluated for radiochemical purity, immunoreactivity, cell toxicity and structure integrity as ...

The ultrastructure of papain and pepsin-digested products of human IgM globulins has been analyzed. Papain digestion was performed both in the presence and absence of cysteine. The Fcmicro fragment was found to represent the central ring structure in the intact IgM molecule, plus a minor part of the appendages extending from the ring. The Fcmicro ring structure was occasionally seen to be compo...

A hierarchical zeolitic imidazolate framework-8 (micro/meso-ZIF-8) was fabricated by using cetyltrimethylammonium bromide as a structure-controlling agent and l-histidine as co-templates. Compared to the conventional microporous ZIF-8 (micro-ZIF-8), the hierarchical porous structure of micro/meso-ZIF-8 contains micropores and maximum mesopores of around 35.6 nm. The as-prepared hierarchical mic...
