A modified diamond–photonics based metrology is proposed to explore the magnetic fields created by agglomerates of nanoparticles (MNPs). MNPs are promising for environmental and medical applications; those cancer hyperthermia treatments small superparamagnetic <20 nm iron oxide particles. Inside cells, they assemble in larger MNP agglomerates, reaching cross-sections several micrometers. Here, ...

Context. Nano-diamonds remain an intriguing component of the dust in few sources where they have been observed emission. Aims. This work focusses on nano-diamonds circumstellar discs and is attempt to derive critical information about their possible sizes, compositions, evolution using a recently derived set optical constants. Methods. The complex indices refraction properties (the efficiency f...

Rhombellanes are mathematical structures existing in various environments, in crystal or quasicrystal networks, or even in their homeomorphs, further possible becoming real molecules. Rhombellanes originate in the K2.3 complete bipartite graph, a tile found in the linear polymeric staffanes. In close analogy, a rod-like polymer derived from hexahydroxy-cyclohexane was imagined. Further, the ide...

The work of adhesion is an interfacial materials property that is often extracted from atomic force microscope (AFM) measurements of the pull-off force for tips in contact with flat substrates. Such measurements rely on the use of continuum contact mechanics models, which ignore the atomic structure and contain other assumptions that can be challenging to justify from experiments alone. In this...
