Volume 1: Pipeline and Facilities Integrity.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) Notice of Proposed Rulemaking (NPRM), with Docket No. PHMSA-2011-0023, substantially revises 49 CFR Part 191 and 192. Notable among these changes was the addition of §192.607, verifi

Ni1–xFexOOH thin films prepared via cathodic electrodeposition have been demonstrated to be highly active catalysts for the oxygen evolution reaction (OER) in basic media. Integration of these catalysts with light-absorbing semiconductors is requir

A new theory on the origin of hysteresis in first order phase transformations was evaluated for its applicability to the phase transformation behavior in the Cs_(1 − x)Rb_xH_2PO_4 solid solution system. Specifically, the correlation between λ_2, t

A new series of compounds with general chemical formula Ba_(3−x)K_(x)H_(x)(PO_4)_2 has been successfully prepared. This particular stoichiometry was targeted as a candidate solid-state proton conductor because of its anticipated structural similari

Fuel cells based on CsH2PO4 electrolytes have demonstrated promising power densities, but the kinetics of electrode reactions remain largely uncharacterized. Here, the hydrogen oxidation kinetics of Pd and Pt thin film electrodes on CsH2PO4 are probe
