Contribution of epilithic diatoms to benthic−pelagic coupling in a temperate river [PDF]

, 2013
Water residence time in the middle course of rivers is often too short to allow substantial phytoplankton development, and primary production is essentially provided by benthic phototrophic biofilms.

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

The diatom test for drowning: an unreported source of diatom contamination

International Journal of Legal Medicine
Summary We describe here a previously unreported source of diatom contamination that may prove relevant in routine diatom analysis in suspected drowning cases. Glass microscope slides utilized in the process, during their manufacture, undergo a washing process, after which, diatomaceous earth (kieselguhr, fossil diatoms) is added to avoid ...

Accelerating SCF Convergence Through Equivariant Density‐Matrix Learning and Analytic Refinement

Chemistry – A European Journal, EarlyView.
Machine learning predicts physically consistent one‐electron reduced density matrices that provide efficient initial guesses for self‐consistent field calculations. Across diverse molecular systems, this warm‐start strategy reduces the required self‐consistent‐field (SCF) iterations by up to 80% while preserving converged energies and atomic forces ...

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Using diatoms to understand climate-nutrient interactions in Esthwaite Water, England: evidence from observational and palaeolimnological records [PDF]

, 2010
Numerous aquatic systems have experienced eutrophication for several decades and now face the additional pressure of climate change. In order to effectively manage lake systems, a fuller understanding of the impacts of climate and nutrients on lake ...
