ABSTRACT
Electrical double layer transistors using ionic liquids as the gate and ZnO as the semiconductor exhibit stable operation in the presence of redox active additives. The characteristics of the device enable single components with the response of a Schmitt trigger.

A technique for embedding human undecalcified tooth specimens in Technovit® 9100 was developed, which permits immunohistological evaluation of pulp tissue in serial ground sections. Human molars were divided into 14-18 sections of about 23 µm thickness. Immunohistological double staining for S-100 and CD34 revealed unique associations of myelinated nerve fibre bundles with arterioles, which continued through the entire tooth pulp. These arterioles were not only accompanied by, but partially or totally enveloped in longitudinally orientated myelinated nerve fibre bundles. We speculate that this unique arrangement may mechanically support the arterioles and alleviate detection or regulation of their contraction state by sensory nerve cells.
