Finite element analysis of fluid-filled elastic piping systems [PDF]
, 1983 Two finite element procedures are described for predicting the dynamic response of general 3-D fluid-filled elastic piping systems. The first approach, a low frequency procedure, models each straight pipe or elbow as a sequence of beams.

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces
Advanced Functional Materials, EarlyView.The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

Heat and Moisture Conduction in Unsaturated Soils [PDF]
, 1975 Mathematical models are developed for the prediction of heat transfer from hot water pipes buried in the soil. Heat transfer in the absence of moisture transfer is described as a function of the difference between the temperature of the pipe and the ...

Advanced Functional Materials, EarlyView.A synergistic strategy combining A‐site deficiency and B‐site nickel doping yielded a BCFZYN‐095‐01 nanocomposite air electrode for reversible protonic ceramic cells with superior ORR/OER activities. B‐site deficiency in the perovskite lattice enhances proton conduction, and nickel doping within the bulk facilitates oxygen transport.

Advanced Functional Materials, EarlyView.A Ni‐doped PBSCN20 air electrode is proposed as a promising air electrode material for reversible protonic ceramic cells. An isovalent doping significantly facilitates oxygen vacancy formation and proton uptake while simultaneously reducing the energy barrier for proton migration.
