The present invention provides a method for forming a thermal inkjet printhead, comprising at least the following steps: providing a semiconductor wafer including an integrated electronic circuit and a section for forming a thermal actuator element, the integrated circuit comprising at least: a thermal insulating layer formed over a substrate; and a first metal layer formed over the thermal insulating layer; wherein the first metal layer extends into the section for forming the thermal actuator element; and etching a section for forming a thermal actuator element to the first metal layer such that the first metal layer is acting as an etch stop layer. Further there is provided a thermal inkjet printhead formed by a method of the present invention and a semiconductor wafer for forming the thermal inkjet printheads by a method of the present invention.

A Liquid, comprising an hydrophobic flavonoid derivative electrochemically non-active, that is capable of restoring its electrochemical activity, the concentration of the flavonoid derivative being 10 ppm by weight or less, and an organic substance in an amount of 90% by weight or more.

Method for liquid authentication by detection of flavonoid derivatives

The present invention relates to markers for liquids that can be used to authenticate the origin and genuineness of a liquid, preferably a bulk liquid such as fuel. For this purpose, the present invention teaches the use of a polymer capable of forming a semiconducting polymer particle (pdot) in the liquid in small amounts. The invention encompasses a liquid comprising a) a polymer that is capable of forming a semiconducting polymer particle (pdot), the concentration of the polymer being 10 ppm by weight or less, and b) an organic substance in an amount of 90% by weight or more. The invention furthermore envisages the use of such a polymer as an authenticating marker in a liquid, preferably a fuel, and a method for authenticating the genuineness and/or origin of a liquid comprising a polymer capable of forming a semiconducting polymer particle (pdot), comprising the steps
