Development of a Boron Nitride-Filled Dental Adhesive System.

There is a dearth of adhesive systems capable of forming stable bonds between restorative materials and tooth surfaces. To address the concern, this study determined the effects of using methacrylate-functionalized boron nitride nanosheets (BNNSs) in a polymeric dental adhesive system. The bisphenol A glycidyl dimethacrylate (BisGMA):2 hydroxyethyl methacrylate (HEMA) (60:40) adhesive monomer blend with a photoinitiator was filled with 0 wt% (control), 0.

[Acoustic quality and urban health-more than just noise and silence].

New approaches in urban development are required to transform cities into sustainable places. This demands a higher degree of urban density, which is hardly conceivable without an increase in sound - mostly in the form of noise. To achieve a high level of acceptance for densification, high-quality and acoustically pleasant urban spaces are essential.
