Sedimentation in Coal-Water Slurry Pipelining [PDF]
, 2000 In this chapter we present an overview of recent investigations on the problem of sedimentation related to the pipelining of a coal-water slurry. The two main aspects of the problem are the determination of the sedimentation velocity and the understanding and modeling of the dynamics of the sedimentation bed that accumulates on the bottom of the pipe ...

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material
Advanced Science, EarlyView.Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...
