Some embodiments presented here relate to chemical sensors with enhanced sensitivity and selectivity. In an embodiment, the sensor is a composite thin film that comprises (e.g., is made of) chemically-modified carbon black and a chemically-sensitive polymer base. By grafting gold nanoparticles on carbon black, the number of binding sites on the sensor thin film is increased, thereby increasing the sensitivity. Furthermore, ligand attached gold nanoparticles are grafted on carbon black to increase the binding sites on the sensor thin film in some embodiments, which results in increased sensitivity as well as improved selectivity in some cases.

When long chain primary alcohols are into expanded polystyrene (EPS) containing an additive such as carbon black or graphite to give gray EPS, the long chain primary alcohols act as color enhancing agents and generate a darker color as compared with an otherwise identical gray EPS absent the additive.

The present invention relates to a water-based ink that contains pigment-containing polyester-based resin particles A, pigment-free polyester-based resin particles B, an organic solvent and water, in which a content of an organic solvent C having a boiling point of not higher than 235 C. in a whole amount of the organic solvent is not less than 90% by mass. The water-based ink of the present invention can be improved in rub fastness, solvent resistance and adhesion to a non-water absorbing printing medium with good balance therebetween, even when printed on the non-water absorbing printing medium.
