For smaller NPs such as 10nm, the Neel relaxation mechanism prevails over the Brownian one, meaningτ=τNand vice-versa for larger NPs (τ=τB). Both relaxation mechanisms directly affect themagnetization curvesof the NPs and consequently, their performance forbiomedical applications. ...

the new document have been in use for decades, it has not been an easy matter to reach agreement upon the precise shades of meaning which attach to some of these terms, and it will prevent further confusion from developing in the literature if their future use follows the IUPAC ...
Covalent network crystals, sometimes simply called network crystals, are held together by covalent bonds between their constituent atoms. (Note that covalent network crystals are atomic solids, meaning they cannot be made out of molecules.) They are very hard solids, have high melting points and do...
Ferromagnetic glasses are mechanically hard materials, but they are magnetically soft, meaning that they are easily magnetized by small magnetic fields. Also, because of their disordered atomic-scale structure, they have higher electrical resistance than conventional (crystalline) magnetic materials. The ...
Sodium polyacrylate is an amazing water absorber -- it can absorb 200 to 300 times its weight in tap water (even more if the water is distilled) and hold it in a gooey gel. Sodium polyacrylate is a polymer, meaning that it consists of chains of identical units (monomers). The monomer ...
