Combined Foaming and Surface Structuring of Polymers With Supercritical Carbon Dioxide (scCO2) Applying an Incomplete Saturation Strategy

open access: yesJournal of Applied Polymer Science, EarlyView.
Combined foaming and structuring of polymer samples by processing with supercritical CO2 leads to nano‐ and microstructured surfaces on top of perfectly white polymer sheets. ABSTRACT Supercritical carbon dioxide (scCO2) is a widely applied solvent utilized in many physical–chemical processes, including the foaming or structuring of polymers.

An Ignored Wind Generates More Electricity: A Solar Updraft Tower to a Wind Solar Tower

open access: yesAn Ignored Wind Generates More Electricity: A Solar Updraft Tower to a Wind Solar Tower
A solar updraft tower is one of the wind power generation plants which utilizes solar energy. The purpose of this study was to ascertain whether the tower was also able to utilize crosswind energy. Wind tunnel experiments and numerical simulations were conducted simulating the crosswind.

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

open access: yesAdvanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Spatial metrics in fire ecology: seeking consistency amidst complexity

open access: yesBiological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...
