Comparison of Decision Rules for Subsurface Drip Irrigation Practices Using a Nonlinear Mathematical Programming Model

open access: yes
A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation).

Reconstruction of Nickel Chalcogenide Induced Ruthenium Nanoparticles Embedding for Oxygen Evolution: Mechanism Switching Enables Enhanced Catalytic Activity

open access: yesAdvanced Science, EarlyView.
Ru nanoparticles supported nickel chalcogens (Ru/NiX, X = S, Se), which enable fast electrooxidation to form an adaptively Ru embedding structure, featured by the compressed Ru─O─Ni bridge bonds at the Ru/NiOOH interface. On the one hand, Ru nanoparticles have a high affinity for capturing the OH−, consequently increasing the *O radical coverage.

CO2‐Induced Reverse Lattice Oxygen Spillover on Pt/CeO2 Enables Sulfur‐Resistant Dry Reforming of Methane

open access: yesAngewandte Chemie, EarlyView.
A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Bifurcation of *COOH Pathway Determines HCOOH Formation in CO2 Electroreduction on Bismuth

open access: yesAngewandte Chemie, EarlyView.
Driven by the mechanistic debate of Bi‐catalyzed CO2‐to‐HCOOH conversion, ambiguity remains regarding true reaction pathways. To resolve this, we combined constant‐potential AIMD simulations with spectroscopic evidence to analyze the competitive pathways.

Decoupling Chemical and Mechanical Contributions to Capacity Fading in Ni‐Rich Cathodes for Sulfide‐Based All‐Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Ni‐rich cathodes in sulfide‐based ASSBs undergo intertwined (electro)chemical and mechanical degradation. Here, a new diagnostic framework is presented to decouple each contribution by partitioning capacity fading into charge and discharge fading.

Subsurface fault and colluvial wedge detection using resistivity, refraction tomography and seismic reflection

open access: yes, 2012
Electric resistivity tomography (ERT), seismic refraction tomography, and seismic reflection are widely used in shallow geological applications such as fault detection. In this work we use the three methods to find and trace a shallow subsurface fault. A

Formation of subsurface oxygen species and its high activity toward CO oxidation over silver catalysts

open access: yes, 2005
Silver is well known to show peculiar catalytic activities in several oxidation reactions. In the present paper, we investigate the catalytic activity of silver catalysts toward CO-gelective oxidation in H-2.
