DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS

DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS Dendrimers are a new class of synthetic polymers which have a tree or star shape like structure, with a central core, interior branches and terminal groups which embellish the surface. It can be synthesized by a repetitive step-growth polymerization process. They are highly branched and monodisperse… read more: http://www.pharmatutor.org/articles/dendrimer-novel-system-in-pharmaceuticals Crystal… Continue reading DENDRIMER: A NOVEL SYSTEM IN PHARMACEUTICALS

240 boron atoms in a single molecular species

The cuboctahedron consists of copper paddle-wheel nodes and carborane–isophthalic acids Scientists in the US have made a molecular species containing the highest number of boron atoms ever recorded in a crystallographically characterised molecular species. The unique supramolecular cuboctahedron contains 240 boron atoms and was synthesised by Chad Mirkin and colleagues at Northwestern University in Evanston, Illinois, via coordination-driven… Continue reading 240 boron atoms in a single molecular species

Magnetism of single molecule controlled by voltage

The molecule of about 2 nm in size is kept stable between two metal electrodes for several days. Image: Christian Grupe/KIT A team of physicists has succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single molecule. This discovery is… Continue reading Magnetism of single molecule controlled by voltage
