Projections for headwater catchments of the Tarim River reveal glacier retreat and decreasing surface water availability but uncertainties are large

open access: yesEnvironmental Research Letters, 2016
In the Tarim River Basin, water resources from the mountain areas play a key role due to the extremely arid climate of the lowlands. This study presents an analysis of future climate change impacts on glaciers and surface water availability for headwater

Ground-penetrating radar studies in Svalbard aimed to the calculation of the ice volume of its glaciers

open access: yesCuadernos de Investigación Geográfica, 2016
During the period 1999-2014, the Group of Numerical Simulation in Sciences and Engineering of Universidad Politécnica de Madrid carried out many ground-penetrating radar campaigns in Svalbard, aimed to the study of glacier ice-thickness and the physical ...

Improving Interlayer Interactions in Proton Exchange Membrane Fuel Cell through Carbon Nanotube‐Based Catalyst Design

open access: yesAdvanced Science, EarlyView.
This review highlights how carbon nanotube (CNT)–based catalyst designs enhance proton exchange membrane fuel cell (PEMFC) performance by improving interlayer interactions. Vertically aligned CNTs facilitate water management, mass transfer, and electron conduction while promoting effective active sites and reducing interfacial resistance.

Aqueous and Surfactant‐Free Synthesis of Nanoscale Covalent Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
We report an aqueous, surfactant‐free, and versatile synthesis method for imine‐linked nanoCOFs incorporating porphyrin units, with tunable size and morphology. The resulting nanoCOFs exhibit excellent aqueous dispersibility, strong light absorption, and significantly enhanced photocatalytic activity.

Biomechanical Phenotyping Reveals Unique Mechanobiological Signatures of Early‐Onset Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies a unique physical signature of colorectal cancer in younger adults: their tissues are mechanically stiffer than those in older patients with the same cancer. Furthermore, stromal remodeling in early‐onset colorectal cancer promotes epithelial mechanotransduction and proliferation, showing how mechanical alterations in the tissue ...
