High‐throughput Photocatalytic Reactor With in Operando Characterisation for Fast Screening of Materials for the Photodegradation of Water‐Borne Pollutants

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel fast‐screening photocatalytic reactor system (FaS‐PhoReS) using terrestrial sunlight is able to measure the in operando photodegradation of 32 samples at once, and does not suffer from the common problem of sample evaporation. Four photostable 12 dyes are used to investigate the photocatalytic performance of TiO2 and ZnO samples in both film ...

Investigation of Space Weather Effects by Swarm Magnetic Field Data: The SFAC Index

open access: yesGeophysical Research Letters
The three Swarm satellites provide an optimum, low Earth orbit (LEO) and multi‐spacecraft platform, to explore for the first time the local correlation between field‐aligned currents (FACs), auroral electrojets, and magnetic perturbations at the Earth's ...

An Introduction to Magnetospheric Physics by Means of Simple Models [PDF]

open access: yes
The large scale structure and behavior of the Earth's magnetosphere is discussed. The model is suitable for inclusion in courses on space physics, plasmas, astrophysics or the Earth's environment, as well as for self-study.

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

Observations of the Earth's magnetic field from the Space Station: Measurement at high and extremely low altitude using Space Station-controlled free-flyers [PDF]

open access: yes
Simulation studies established that the main (core), crustal and electrojet components of the Earth's magnetic field can be observed with greater resolution or over a longer time-base than is presently possible by using the capabilities provided by the ...

Integration of Plasmonic Nanoheaters for Rapid and Tunable Light‐Driven Phase Transitions in VO₂ Nanocomposites

open access: yesAdvanced Materials Interfaces, EarlyView.
Gold plasmonic nanoparticles are integrated into VO₂ nanopowders to enable rapid, tunable, light‐driven phase transitions. This study demonstrates a new pathway for controlling phase‐change behavior with localized photothermal effects, opening opportunities for reconfigurable optical and electronic devices.

Geomagnetic Information Model for 2019

open access: yesKartografija i Geoinformacije, 2019
In the narrow sense, “Geomagnetic Information” (GI) refers to the Earth’s magnetic field declination (D) and its annual variation (AVD) as marginal information of official and military maps.

Sol–Gel Thin Films for the Protection of Ancient Glass Artifacts: A Performance Comparison Between Inorganic and Hybrid Silica Compositions

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...
