Container structures are ubiquitous in nature, with examples including viruses and various protein assemblies. Researchers at the University of South Dakota have designed and synthesized a series of synthetic container molecules termed metal-organic super-containers (MOSCs) because they are assembled from container precursors, metal ions, and organic...

Method of Growing Germanium Crystals

This new method uses a quartz shield to isolate the germanium that would otherwise be contaminated by the stainless steel chamber, insulation materials, or the graphite crucible. Doctors Mei and Wang also determined that use of a load scale can control the crystal diameter and ensure that all melted germanium is used in crystal production and thus removed...

Electrical Ion Sensors Based on MOSCs

Although metal organic frameworks (MOFs) have proven to be effective for electronic ion sensing, they lack key desirable characteristics such as solution processability due to their insolubility in most common solvents. Metal-organic supercontainers (MOSCs) have a significant advantage over MOFs, as they can be readily dispersed in solution while retaining...
