S‐Nitrosothiols as Thiol‐Protecting Groups for Controlled Thiol‐Maleimide Crosslinking of Homogeneous Soft Hydrogels

open access: yesAdvanced Materials, EarlyView.
Rapid thiol‐maleimide addition frequently outpaces mixing, resulting in heterogeneous hydrogels. S‐nitrosothiols act as thiol‐protecting groups, allowing uniform mixing with maleimide‐functionalized polymers before gelation. Sodium thiosulfate or sodium ascorbate then regenerates thiols on demand, triggering controlled thiol‐maleimide crosslinking ...

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 ...

Enabling a Digital Earth for methane emissions management with equal-area discrete global grids

open access: yesInternational Journal of Digital Earth
We develop a spatially explicit methane inventory for Alberta’s upstream oil and gas sector using the rHEALPix Discrete Global Grid System. The objective is to demonstrate an equal-area, hierarchy-aware framework that assigns facility-reported emissions ...

Three dimensional modeling and geometric properties of oil plant equipment from terrestrial laser scanner observations [PDF]

open access: yesGeodesy and Cartography, 2018
Terrestrial laser scanner (TLS) is a new class of survey instruments to capture spatial data developed rapidly. A perfect facility in the oil industry does not exist. As facilities age, oil and gas companies often need to revamp their plants to make sure

Fast Hydrogel Micro‐Actuators Driven by Electric Fields

open access: yesAdvanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...
