Volatile fatty acids (VFAs) from biomass fermentation offer a sustainable alternative to petroleum-based chemicals, serving as building blocks for bioplastics, pharmaceuticals, and more. However, separating and purifying these acids from fermentation broths remains technically challenging.

A new study in the Journal of The Electrochemical Society, selected as an Editors’ Choice article, addresses this bottleneck. Researchers Riccardo Candeago, Nidhish Lella, Wangsuk Oh, Ping Liu, and Xiao Su developed a physics-based model of redox-mediated (more…)

We are pleased to spotlight a publication from the ECS Journal of Solid State Science and Technology (JSS):

“Low-Damage Atomic Layer Etching for Contact Resistance Reduction in Millimeter Wave AlGaN/GaN HEMTs on Si” (DOI: 10.1149/2162-8777/ae1ced) by Hsuan-Yao Huang et al. (2025) —available fully open access.

In this work, the authors address one of the key bottlenecks for high-frequency GaN electronics: ohmic contact resistance and accompanying device damage in high-electron-mobility transistors (HEMTs) built on Si substrates. Conventional etching methods for the ohmic-recess process often introduce plasma-induced damage, rough surfaces, and degraded channel performance. (more…)

ECS Sensors Plus is pleased to highlight a recent contribution that showcases the power of material innovation in enhancing electrochemical sensing technologies. In their new article, “Application of a g-C₃N₄@nZVI/CNTs Modified Carbon Paste Electrode for Uric Acid Detection in Spiked Urine Samples,” Aya A. Mouhamed, Ola G. Hussein, Maria Osama Mekhail, Tony Victor Zaki, Amr M. Mahmoud, and Jeffrey G. Bell present a promising approach for accurate, sensitive uric acid detection.

The research team developed a carbon paste electrode modified with a uniquely engineered g-C₃N₄@nZVI/CNT nanocomposite. By combining graphitic carbon nitride’s high surface area, nano zero-valent iron’s catalytic activity, and carbon nanotubes’ conductivity, the authors created a synergistic platform capable of boosting electron transfer and improving analytical performance.

In celebration of International Open Access Week 2025 (October 20–26), The Electrochemical Society (ECS) is proud to reaffirm our longstanding commitment to open science and equitable access to knowledge. This year’s theme, “Who Owns Knowledge?”, invites the global research community to reflect on how scholarly information is shared, who can access it, and how collective progress depends on removing barriers to discovery.

In honor of Open Access Week, ECS will remove the paywall for all ECS subscription-based content across our journal portfolio for the open access week period. From October 20 through October 26, every reader, regardless of institutional affiliation or funding, will have free access to our full library of peer-reviewed research.

This initiative underscores our commitment to advancing science for the benefit of humanity, the mission that has guided ECS since 1902. Open science accelerates innovation, promotes collaboration across borders and disciplines, and ensures that every researcher, educator, and student can contribute to solving the world’s most pressing challenges from sustainable energy to clean water and beyond.

The Journal of The Electrochemical Society (JES) proudly celebrates the rapid success of the open access article “Understanding Lithium Deposition in Lithium-Ion Batteries: The Link between Impedance Results and Electrochemical Behavior.” In just a few short weeks since publication, this paper has risen to the top of JES’s Most Read Articles of 2025, capturing global attention for its clarity, rigor, and real-world relevance.

Illuminating Lithium Deposition

Lithium deposition, or plating, remains a major challenge in advancing lithium-ion batteries. When metallic lithium forms during fast charging or under non-ideal conditions, it can cause dendrites, capacity loss, and safety risks. This groundbreaking study offers fresh insight by directly linking impedance spectroscopy results to electrochemical deposition behavior, providing researchers with a predictive framework to better understand and control plating phenomena.

By connecting impedance signals with changes in morphology and capacity, the authors reveal when and how lithium deposition occurs. Their work identifies spectral features associated with plating onset, evolving interfacial kinetics, and irreversible capacity fade—insights that will guide the design of safer and more durable energy storage systems.
