Measuring the mass of atoms through collisions with imaging electrons in an electron microscope

Imaging electrons of transmission electron microscopes can be used in research to drive and study the dynamics of atomic processes, especially in materials such as graphene (a one-atom-thick carbon layer). The measurement have resulted in a demand for an accurate theoretical description of the elastic collision process between the imaging electrons...

Stable isotope labelled amino acids from cell walls/cell membranes

Mass spectrometry is becoming a cutting edge technology in the fields of clinical diagnostics and personalized medicine. A key application is the quantification and/or assessment of fold changes of molecules derived from primary and secondary metabolism. Samples derived from human origin contain a wide variety of metabolites at a wide range of concentrations,...

NKCC inhibitors for stroke

Stroke is the second leading cause of death and the leading cause of disability worldwide. 60 percent of those who suffer a stroke die or become dependent. The irrevocable harm caused by interrupting blood flow to the brain unfolds hours to days after the initial blockage, therefore, it is critical to identify early interventions that could reduce neuronal...

Mirror Image Microarrays

Microarrays are versatile and widely used tools for high-throughput screening methods. Conventional light-directed synthesis of microarrays is a relatively inefficient and expensive process that is wasteful of raw materials.Researchers at the University of Vienna, Faculty of Chemistry have improved existing synthesis methods by developing a unique flow...

Auxiliary-assisted glycopeptide synthesis

For many eukaryotic proteins, processing by post-translational modifications such as glycosylation is a critical step for correct folding and achievement of biological activity. These modifications that occur naturally within eukaryotic cells have to be replicated when preparing peptides and proteins that are chemically synthesized or recombinantly-produced...

Procedure for the identification of aroma-active compounds (Bitterness Assay)

Many active pharmaceutical ingredients taste bitter and are thus aversive to children, many adults and animals, who may fail to comply with medication and complete their treatment. Encapsulation of bitter components is not an effective solution for children or anyone who has difficulties swallowing solid dose forms. The use of sugars or acids as taste-masking...
