ZnTe (Eg = 2.26 eV) and CdTe (Eg = 1.5 eV) were studied as possible candidates for a photocathode in the photoelectro‐chemical production of hydrogen. Current‐potential relationships with and without light, photocurrent‐wavelength relationships at various potentials, and the flatband potential, were measured for both electrodes in 1 N NaOH solution. the stabilities of both electrodes in NaOH solution were also examined. CdTe is a possible photocathode, but ZnTe is unacceptable, because the photocurrent appears at a too‐negative potential in relation to its negative flatband potential, and because of its low stability.

This article explores the emergence of the dominant mobile social media platform in Japan, LINE. In particular, the article focuses upon its usage to maintain familial ties, especially between matriarchal connections. Drawing upon ethnographic work with 12 families over 3 years, this article seeks to provide a detailed and nuanced sense of how social mobile media is deployed intergenerationally.
