Single-use applicators

Insertion of non-coordinated solvent molecules in these networks can stabilise the LS state. For instance, the transition temperatures of the system [Fe(hyetrz)3] (3-nitrophenylsulfonate)2 Solv depend dramatically on the nature of the solvent as follows Solv=0 (T1/2 105 K)room temperature) [43]. A similar influence of non-coordinated solvent molecules was first reported for the mononuclear complexes [Fe(2-picolylamine)3]Cl2 Solv [44]. The hydrate [Fe(hyetrz)3](3-nitrophenylsulfonate)2-3H20 loses water when heated and this is accompanied by a change to the HS state [45]. The significant feature of this system is that the HS anhydrous sample does not re-ab-sorb water under a normal atmosphere. Thus it can be the basis for single use applications. Several other examples of changes in spin state induced by water removal have been identified for ID polymeric chain compounds following this discovery [46-49]. 

To produce solid based lubricants, h-BN is added to plastics, rubbers, and resins in various amounts. BN dip coated surfaces are used for single-use application.
