Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Bioelectromics of a photosynthetic microalgae assisted microbial fuel cell for wastewater treatment and value added production

Scientific Reports
Power generation and recovery of value-added products using microalgae, Haematococcus lacustris is tested in a dual chamber photosynthetic microalgae-assisted microbial fuel cell (PMA-MFCt1). The microalgal cells in conical flask act as control.

A simple method for taxon-specific purification of diatom frustules from ocean sediments using a cell sorter

Progress in Earth and Planetary Science, 2023
It is necessary to purify diatom frustules by taxon to perform accurate geochemical analyses of diatom fossils preserved in sediments. However, the small size of diatoms has hitherto prevented taxon-specific purification; therefore, previous geochemical ...

The Preparatory (Anti)Bonding Character of Molecular Orbitals

Advanced Science, EarlyView.
Herein, a concept to qualitatively predict changes in bond dissociation energies upon reduction or oxidation of molecular compounds is introduced. Changing the population of so‐called preparatory molecular orbitals influences how molecular fragments are relaxing after bond cleavage, which is shown for isolated organometallic aluminum compounds as well ...

Spatial distribution of surface-sediment diatom assemblages from 45 Tibetan Plateau lakes and the development of a salinity transfer function

Ecological Indicators, 2023
The Tibetan Plateau (TP) is often referred to as the “Asian Water Tower”, as it plays a crucial role in supplying water for ∼1.9 billion people.

Culturing Diatoms

, 2023
In this chapter, we provide information on cultures of diatoms, starting with a brief introduction of the history of diatom culture collections. We present a synopsis of diatom strains currently available in culture collections and their representation in terms of habitat diversity, geographical distribution, phylogeny and taxonomic diversity.

Host specificity of Podocystis adriatica on the red alga Heterosiphonia crispella from Senegal

, 1994
Podocystis adriatica (Kützing) Ralfs in Pritehard is reported from Senegal as a host specific epiphyte on the red alga Heterosiphonia crispella (C. Agardh) Wynne. The diatom was common on six collections of H. crispella from three sites, and absent on ca.

Absorption of Broadband Low‐Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing

Advanced Science, EarlyView.
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.
