“Basic human things”: Investigating vehicle residents' continually fractured (information) landscapes

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This ethnographic study explores vehicle residents' information practices in the United States (US). Vehicle residents are people whose primary means of housing is a vehicle. This work builds on previous research encompassing transitions and fractured (information) landscapes. Using fractured information landscapes as the theoretical framework,

Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).
