Researchers studied gold nanoparticles supported by carbon atoms and found that a large carbon shell can physically squeeze together particles, triggering a merging process. This discovery suggests encapsulating individual metal nanoparticles within carbon shells could prevent uncontrolled size changes in nanoparticle arrays.
The National Institute of Standards and Technology (NIST) has released Standard Reference Material (SRM) 1d for Indiana limestone, which is a critical component in various industries. The SRM will support the production of cement, concrete, and iron steel.
A stable cluster of aluminum atoms, Al13, demonstrates properties similar to those of a halogen, retaining its properties during chemical reactions and in reaction products. The research uses experimental evidence and theoretical calculations to show that the cluster can be considered a 'superhalogen' atom.
Researchers have successfully grown monomolecular films of a helical polypeptide, poly-gamma-benzyl-L-glutamate, directly from a flat surface. The films exhibit comparable polarization to conventional ferroelectric materials, with potential applications in piezo- and pyroelectric devices.
Researchers at Georgia Institute of Technology have isolated massive gold-cluster molecules with exceptional quantum properties. The gold cluster materials can be used in single-electronics and exhibit charge-quantization effects, offering a breakthrough for nanoelectronic applications.
