The growing popularity of gamification in the global environment increases the importance of balancing factors that affect user engagement, satisfaction and acceptability in different cultures. While the main motivation behind gamifying software systems is to improve user engagement, an adverse effect might happen if the design and functionality did not consider users' cultural requirements.

CdS nanoparticles functionalized by electroactive oligothiophenes, with narrow size distribution, have been prepared and characterized. The structure of the hybrid product was investigated by TEM, XRD, optical and FTIR spectroscopy. The modified nanoparticles consist of a few tens of oligothiophene units attached to the CdS core. The grafting of conjugated oligomers to nanoparticles was made possible by complexing the dangling cadmium ion on the nanoparticle surface
