Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

open access: yesAdvanced Materials, EarlyView.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.

Influence of shear on rheology of the crude oil treated by flow improver

open access: yesEnergy Reports, 2019
Because the influence of shear on the rheology of waxy crude oil must be considered according to the composition and structure of the waxy crude oil transported via pipeline when a new pipeline is constructed, the risks associated with changes in the ...

Decomposing Crude Price Differentials: Domestic Shipping Constraints or the Crude Oil Export Ban?

open access: yes, 2017
Over the past five years the U.S. domestic crude benchmark, WTI, diverged considerably from its foreign counterpart, Brent. Some studies pointed to the crude oil export ban as the main culprit for this divergence, but pipeline capacity was also scarce ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

open access: yesAdvanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Economic Assessment of a Crude Oil Hydrotreating Process

open access: yesChemical Engineering Transactions, 2019
This paper presents the economic assessment of a crude oil hydrotreating process with a crude distillation unit. The hydrotreating of crude oil is a novel process that has great economic potential but has not been implemented widely in practice, where ...

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.
