Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Environment and productivities in developed and developing countries : the case of carbon dioxide and sulfur dioxide [PDF]

open access: yes, 2010
We propose a productivity index for undesirable outputs such as carbon dioxide (CO2) and sulfur dioxide (SO2) emissions and measure it using data from 51 developed and developing countries over the period 1971-2000.

Effect of volcanic sulfur dioxide on solar UV irradiance during the 2023 Fagradalsfjall eruption in Reykjavík, Iceland

open access: yesMeteorologische Zeitschrift
Sulfur dioxide is an important atmospheric gas that can attenuate solar ultraviolet radiation. It can be found in greater quantities in highly polluted areas and especially in volcanic plumes.

Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Sulfur dioxide plume erupts from Vanuatu volcano [PDF]

open access: yes, 2012
On the tiny island of Tanna, Vanuatu in the South Pacific is one of the world's most active volcanoes: Mt Yasur. The NASA Aura satellite orbited overhead today (March 18, 2011), the Ozone Mapping Instrument detected a large sulfur dioxide plume being ...

Effect of Drying Method on Sulfur Dioxide Content in Edible Mushrooms and Endogenous Transformation Factors

open access: yesShipin gongye ke-ji
In this study, dietary risk assessment of sulfur dioxide content in both fresh and dried commercially available edible mushrooms (Tremella fuciformis, Lentinus edodes, and Agaricus blazei) was conducted through risk quotient and point assessment methods.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics

open access: yesAdvanced Materials, EarlyView.
Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...
