A Cross-Linkable Electron-Transport Layer Based on a Fullerene-Benzoxazine Derivative for Inverted Polymer Solar Cells.

The synthesis, optoelectronic characterization and device properties of a cross-linkable fullerene derivative, [6,6]-phenyl-C -butyric benzoxazine ester (PCBB) is reported. PCBB shows all the basic photophysical and electrochemical properties of the parent compound [6,6]-phenyl-C -butyric methyl ester (PCBM). Thermal cross-linking of the benzoxazine moiety in PCBB resulted in the formation of cross-linked, solvent resistive adhesive films (C-PCBB).

Management of a malposed dental implant in the esthetic zone.

With the increased research in the field of dental implantology, there has been an extensive rise in the application of dental implants in various clinical situations. Complications arise with the frequent increase in the placement of dental implants; one of the common difficulties faced is placement of a malposed dental implant. Rehabilitation of prosthetically unfavorable implant is a serious challenge to a restorative dentist, a laboratory technician, and the patient.
