Variations of the earth's magnetic field and rapid climatic cooling: A possible link through changes in global ice volume [PDF]

open access: yes
A possible relationship between large scale changes in global ice volume, variations in the earth's magnetic field, and short term climatic cooling is investigated through a study of the geomagnetic and climatic records of the past 300,000 years.

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 ...

Data use investigation for the magnetic field satellite (MAGSAT) mission: Geomagnetic field forecasting and fluid dynamics of the core [PDF]

open access: yes
MAGSAT data were used to construct a variety of spherical harmonic models of the main geomagnetic field emanating from Earth's liquid core at poch 1980. These models were used to: (1) accurately determine the radius of Earth's core by a magnetic method, (

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.

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.

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 ...

Interlayer‐Mediated Stabilization of Metastable P63cm ScFeO3 on Al2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
This work develops an interlayer‐mediated stabilization method, demonstrated by the deposition of the P63cm phase of ScFeO3 ‐a metastable polymorph that exhibits multiferroic and optical properties not possible in the ground state. Thin films of the P63cm phase of ScFeO3 are stabilized on (0001) Al2O3 by the spontaneous formation of two atomic layers ...

Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

open access: yesAdvanced Materials Interfaces, EarlyView.
The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.
