Sustainable Metal Recovery From E‐Waste: Exploring Greener Leachates in Hydrometallurgical Processes

open access: yesMetalMat, EarlyView.
Recycling of electronic waste to synthesize valuable metals using green leachate. ABSTRACT The accumulation of electronic waste (e‐waste) poses environmental hazards and leads to the loss of valuable metals such as gold, silver, copper, and rare earth elements.

Wet‐Transferred MoS2 on Passivated InP: A Van der Waals Heterostructure for Advanced Optoelectronic Applications

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 5, May 2025.
This study presents a photodetector based on atomically thin MoS2 on an InP substrate, forming an n‐MoS2/p‐InP type‐II staggered heterojunction. The device exhibits excellent rectifying properties with an ideality factor of 1.57 and achieves a peak photoresponsivity of 960 mA W−1, while MoS2 provides stable passivation for InP. III–V semiconductors are

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Porous Modified Calcium Carbonate as an Efficient Carrier for Gallic and Ascorbic Acids in Humidity‐Activated Oxygen Scavenging Systems

open access: yesPackaging Technology and Science, EarlyView.
Porous modified calcium carbonate (MCC) is presented as an efficient carrier for humidity‐activated oxygen scavengers based on gallic acid and ascorbic acid. The porous MCC structure preserves high accessibility of the active compounds, enabling effective oxygen scavenging under high relative humidity, with performance governed by loading level ...

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

open access: yesSystems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

‘A Sort of Armed Argument’: Ireland's Civil War of Words

open access: yesHistory, EarlyView.
Abstract This article sets out to contribute to the study of the languages of European civil wars through outlining and analysing the deployment of language as a weapon by the opposing sides of the Irish independence movement that split over the terms of the Anglo‐Irish Treaty of December 1921.
