We report on a novel biocompatible hierarchical TiO2 porous coating on the surface of Ti, processed via anodic oxidation. The coating consists of large (∼1–20 μm) pores on the microscale and nanotubes (∼50 nm diameter) on the nanoscale. This structure is exciting because of its potential application as a bioactive coating for Ti bone implants. Surface characterization of the coating showed nanotubes of relatively uniform diameter. The interface between TiO2 nanotubes and Ti, studied by transmission electron microscopy, was incoherent. The tubes were also somewhat interconnected.

The giant whitefly is a pest, particularly of Hibiscus and sometimes avocados, in southern California. The insect is unique in that the nymphal stages produce copious quantities of waxy material differing in structure and chemical composition. Adults produce a waxy material (waxy particles) which covers them and surrounding surfaces, and the female also produces a waxy material with which she forms a circular trail of wax strands on the abaxial leaf surface.Waxy particles produced by male and female adults consisted of long-chain aldehydes and alcohols, largely 32 carbons in chain length. As waxy ribbons extruded from anterior abdominal wax plates, they are periodically broken off by the tibia and the resulting particles coat adults, nymphs and surrounding surfaces. The female has a second set of wax plates posteriorly on her abdomen which produce waxy strands. As her abdomen drags along the abaxial leaf surface during oviposition these strands break off forming a waxy trail camouflaging the eggs.The nymphs produce several types of waxy material. Two types are produced at the same time from 10 pores on the dorsal surface; waxy material is extruded as a filament on which a second waxy material curls off as extrusion occurs.
