Tsukuba, Japan—The shapes of simple polyatomic molecules such as carbon dioxide and methane are characterized by a specific symmetry depending on the manner of linking of the atoms. Nano- to ...

Nonspherical clusters of a small number of particles (CMs) have potential applications in coatings, material self-assembly, biomedical diagnostics. The sphere has the smallest surface area under a ...

Particles engineered to spontaneously self-assemble like atoms forming molecules could give rise to new high-tech materials, leading to better optical displays and faster computer chips, researchers ...

(Nanowerk News) Are you ready for the future? Back in 1869, Russia's Dmitri Mendeleev began to classify the elements according to their chemical properties, giving rise to the Periodical Table of ...

Blocking amyloid fibrillization with small molecules is a widely studied strategy for tackling Alzheimer disease and other amyloidoses. But do some of the compounds fail to shape up? In the January 27 ...

An MIT-Berlin group (Katrin Kneipp, [email protected]) has used surface enhanced Raman scattering (SERS) to detect single dye molecules attached to colloidal silver particles suspended in an ...

Density gradient centrifugation is an effective method for the isolation and purification of small particles. Hollow rotors capable of hosting density gradients replace the need for centrifuge tubes ...

A newly developed organohydrogel regulates the transport of hydro- and lipophilic molecules in a single matrix. Not only does the material overcome traditional limitations in dual molecular transport, ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...
