Water, Conflict, and Peace

open access: yesOpen Rivers, 2018
We live on a water planet. As the writer Arthur C. Clark noted, if we didn’t happen to be land-dwelling creatures, we would call our planet Ocean, rather than Earth.

Case Studies of Habitable Trojan Planets in the System of HD 23079

open access: yes, 2011
We investigate the possibility of habitable Trojan planets in the HD 23079 star-planet system. This system consists of a solar-type star and a Jupiter-type planet, which orbits the star near the outer edge of the stellar habitable zone in an orbit of low

Real‐Time, Label‐Free Monitoring of Cell Behavior on a Bioelectronic Scaffold

open access: yesAdvanced Functional Materials, EarlyView.
A bioelectronic nanofibrous scaffold is introduced that supports cell growth while enabling real‐time, label‐free monitoring of cellular behavior through impedance measurements. The system correlates electrical signals with cell viability and surface coverage, offering an integrated platform for studying dynamic biological processes and advancing next ...

Archaeological assessment reveals Earth’s early transformation through land use

open access: yesScience, 2019
A synthetic history of human land use Humans began to leave lasting impacts on Earth's surface starting 10,000 to 8000 years ago. Through a synthetic collaboration with archaeologists around the globe, Stephens et al.

All‐Aqueous Pullulan Fibers Enabling Visible‐to‐Near‐Infrared Waveguiding with Mechanical and Thermal Resilience

open access: yesAdvanced Functional Materials, EarlyView.
Pullulan, a biomass‐derived polysaccharide, is transformed into transparent optical fibers using a solvent‐free borax hydrogel‐spinning method. The fibers outperform PMMA with ≈200 MPa tensile strength and 200 °C stability, while uniquely guiding visible‐to‐NIR light and enabling additive‐free humidity sensing.

Tilted Circumbinary Planetary Systems as Efficient Progenitors of Free-floating Planets

open access: yesThe Astrophysical Journal Letters
The dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet–planet interactions.

Theory‐Guided Design of Non‐Precious Single‐Atom Catalyst for Electrocatalytic Chlorine Evolution

open access: yesAdvanced Functional Materials, EarlyView.
To overcome the reliance on noble metals for the chlorine evolution reaction (CER), we designed a non‐precious single‐atom catalyst (SAC), NiN3O–O. It achieves a low overpotential of 75 mV, 95.8% Cl2 selectivity, and outperforms commercial dimensionally stable anodes (DSAs).

Mechanistic Insights into a Synergistic FeOx/Fe‐N4 System for Practical Nitrate Abatement with Value‐Added Ammonia Recovery

open access: yesAdvanced Functional Materials, EarlyView.
This work provides a novel interpretation of the nitrate reduction mechanism on iron oxides (FeOx) by employing constant‐potential density functional calculations and reports the design and synthesis of a robust and high‐performance Fe3O4/Fe‐N4‐C catalyst with remarkable Faradaic efficiency, current density, and stability under practical reaction ...
