A viscoelastic model of ice stream flow with application to stick-slip motion

Frontiers in Earth Science, 2016
Stick-slip motion such as that observed at Whillans Ice Stream, WestAntarctica, is one example of transient forcing significantly affecting longer-termice-stream dynamics.

Characteristics of the sticky spot of Kamb Ice Stream, West Antarctica [PDF]

, 2017
Amplitude analysis of reflection seismic data reveals the presence of highly variable bed conditions under the main sticky spot and adjacent regions of the Kamb Ice Stream (KIS—formerly ice stream C).

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

LDI, A Lipid Droplet Inhibitor, Disrupts Lipid Accumulation and Modulates Hepatic Lipid Profiles in Fatty Liver

Advanced Materials, EarlyView.
The lipid droplet inhibitor (LDI), templated with large‐pore mesoporous silica and functionalized with PKCα C1A and lipase, targets lipid degradation in fatty liver. The LDI maintains stable association with lipid droplets, thereby suppressing their formation and expansion.

The Space Within: How Architected Voids Promote Tissue Formation

Advanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

Subtemperate sliding reduces periodicity of ice stream temporal variability in a simple model

Journal of Glaciology
Understanding the formation and evolution of fast flowing ice streams is essential to projecting the response of ice sheets to climate forcings. Slow-flowing or stagnant ice streams can slide at low velocities over a bed that is below the bulk melting ...

Porous Iridium Oxide Inverse Opal Catalysts Enable Efficient PEM Water Electrolysis

Advanced Materials, EarlyView.
Porous iridium‐based inverse opal (IrOx‐IO) structures are introduced as high‐performance, unsupported PEM‐WE anode catalysts. Their electrochemical behavior is analyzed through porosity/surface area tuning, voltage breakdown, and circuit modeling.

Ice flow in the northeast Greenland ice stream [PDF]

Annals of Glaciology, 2000
AbstractWe have measured ice flow and detailed topography in northeastern Greenland using satellite-based synthetic-aperture radar (SAR) interferometry. The subject of this study is the large ice stream that drains this quadrant of the ice sheet. A single SAR interferogram allows the measurement of one component of motion over a several-day-long ...

Operando X‐ray Spectroscopy Study of Pd and Pd–Au Laterally Condensed Catalysts during Selective Acetylene Hydrogenation: The Role of Carbon

Advanced Materials, EarlyView.
The selective hydrogenation of acetylene over laterally condensed Pd and Pd–Au catalysts (LCCs) was investigated using operando X‐ray absorption and photoelectron spectroscopy in combination with density functional theory. Pd‐LCCs were found to incorporate significantly more carbon into the metal lattice than Pd–Au LCCs, where the carbon uptake governs

Integrated Lead/Iodine Management for Sustainable Perovskite Solar Modules

Advanced Materials, EarlyView.
Perovskite solar modules face environmental risks from lead and iodine leakage. A dual‐function adsorbent—porphyrin‐modified whitlockite nanocomposites—effectively captures iodine and Pb2+, even under severe damage. Combined with a semi‐closed recycling process, it recovers 96.9% high‐purity PbI2 and reduces residual Pb2+ to <10 ppb, offering an ...
