The Microlensing Planet Finder: Completing the Census of Extrasolar Planets in the Milky Way

open access: yes, 2004
The Microlensing Planet Finder (MPF) is a proposed Discovery mission that will complete the first census of extrasolar planets with sensitivity to planets like those in our own solar system.

Microbial Contribution to Soiling and Its Impact on Photovoltaic Module Soiling in Arid Zones of the Atacama Desert

open access: yesAdvanced Sustainable Systems, EarlyView.
Microorganisms colonizing photovoltaic surfaces in the Atacama desert form biofilms that enhance particle adhesion and reduce energy yield. This study identifies UV‐resistant bacteria and carotenoid‐producing strains that interfere with PV performance.

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

open access: yesAdvanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

open access: yesAdvanced Science, EarlyView.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

A Pan-STARRS Search for Distant Planets: Part 1

open access: yesThe Planetary Science Journal
We present a search for distant planets in Pan-STARRS1. We calibrated our search by injecting an isotropic control population of synthetic detections into Pan-STARRS1 source catalogs, providing a high-fidelity alternative to injecting synthetic sources ...

Planet discovered outside solar system

open access: yesEos, Transactions American Geophysical Union, 1984
Astronomers have reported the discovery of a planet orbiting a star outside our solar system, which, if verified, would be the first time that a direct observation has been made. Using a relatively new technique called speckle interferometry, astronomers from the University of Arizona and the National Optical Astronomy Observatories (NOAO) have ...

Fe2+‐ Induced Activation of Single and Dual Metal Site—Lattice Oxygen Mechanism in Fe Rich NiFe‐LDHs for Oxygen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
Fe‐rich NiFe‐LDH catalysts derived from MOFs, showing superior OER activity via lattice oxygen mechanism activation. ABSTRACT Developing a durable and efficient oxygen evolution reaction (OER) catalyst without noble metals is essential for the economical and sustainable production of hydrogen by alkaline water electrolysis.

Ringed versus Ringless Worlds: How Poynting–Robertson Drag Shapes Rings across the Solar System

open access: yesThe Astrophysical Journal Letters
Planetary rings are not only ubiquitous around the giant planets in the outer solar system, but have also been discovered around several small distant bodies. In contrast, no rings have been observed around any inner solar system objects.

Review: Insight on Porous Carbon Positive Electrode for Sodium‐Ion Capacitors: Interplay Between Synthesis, Properties, and Performance

open access: yesAdvanced Science, EarlyView.
Sodium ion capacitor (SIC) is currently constrained by the low discharge capacity of commercial activated carbon as positive electrode material. This review provides a holistic summary of research efforts on alternative porous carbon materials for SIC. Image created by the authors with www.biorender.com.
