Spectral‐Kinetic Synergy in Au‐Network Engineered FeTiO3: A Multi‐Field Coupling Strategy for Lunar In Situ Resource Utilization

open access: yesAdvanced Science, EarlyView.
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Palaeoproteomic Deconvolution of Physical and Genetic Collagen Mixtures

open access: yesAdvanced Science, EarlyView.
ClassiCOL_v2 uses a novel “peptide patching” framework that treats any collagen sample as a patchwork of peptide sequences derived from phylogenetically related species. This allows the algorithm to simultaneously resolve two previously intractable problems: multi‐species samples and/or database deficiencies.

Characterization of glacial silt and clay using automated mineralogy

open access: yesAnnals of Glaciology, 2019
Glacial erosion produces vast quantities of fine-grained sediment that has a far-reaching impact on Earth surface processes. To gain a better understanding of the production of glacial silt and clay, we use automated mineralogy to quantify the ...

Developing slurries for carbon capture: From synthetic gas mixtures to flue gas

open access: yesAIChE Journal, EarlyView.
Abstract Deep eutectic solvent (DES)‐based systems have recently emerged as promising alternatives to conventional liquid sorbents for CO2 capture due to their tunable properties and potential for enhanced mass transfer. In this work, two DES‐based slurry systems previously developed for CO2 capture, one aqueous and one non‐aqueous, were further ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Ice-sheet scale distribution and morphometry of triangular-shaped hummocks (murtoos): a subglacial landform produced during rapid retreat of the Scandinavian Ice Sheet

open access: yesAnnals of Glaciology, 2019
High-resolution digital elevation models of Finland and Sweden based on LiDAR (Light Detection and Ranging) reveal subglacial landforms in great detail.

Experimental Studies on CO2 Hydrate Formation Kinetics With Kinetic Promoters

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon dioxide (CO2) sequestration by means of gas hydrate formation is a promising method for mitigating global climate change. However, conventional surfactants like sodium dodecyl sulfate (SDS) exhibit limitations such as excessive foaming and environmental toxicity. This study examines the effectiveness and environmental impact of Tween 65

A Survey of Climatic Changes of Namak Lake Basin in the Late Quaternary [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2014
Two important characteristics, alternate climatic fluctuations and human being appearance, distinguish Quaternary from other geology periods. These climatic changes have shown increase and decrease of glacialical scope in high latitudes, but there are ...

The glacial origins of relict ‘pingos’, Wales, UK

open access: yesAnnals of Glaciology, 2019
Ramparted depressions (doughnut-shaped debris-cored ridges with peat- and/or sediment-filled central basins) are commonly perceived to represent the relict collapsed forms of permafrost ground-ice mounds (i.e. pingos or lithalsas).

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...
