In their recent ECS Sensors Plus article, authors Leyllanne K. A. Souza, Maxwell D. Bridges, Thaisa A. Baldo, Wendell K. T. Coltro, and Charles S. Henry introduce an innovative and accessible approach to wearable biosensing by transforming a simple adhesive bandage into a high-performance electrochemical sensor.

Delivering low-cost, non-invasive, real-time health monitoring

As demand grows for non-invasive, real-time health monitoring, sweat has emerged as a valuable biofluid for tracking physiological biomarkers. In this study, researchers developed a flexible sensing platform using laser-induced graphene (LIG), a porous, conductive material created through laser processing, and transferred it onto a commercial adhesive bandage. The result is a lightweight, skin-conformal sensor capable of detecting key metabolites directly from sweat. (more…)

New from the President in the winter 2025 issue of ECS Interface

In “From the President: Advocating for Science = Positively Affecting the World,” ECS President James (Jim) Fenton reflects on the critical role science advocacy plays in shaping a brighter, more equitable future for all.

In a time when science and technology are at the forefront of global progress, this thoughtful piece highlights how each of us—whether you’re a researcher, educator, student, or industry partner—can contribute to positive change by championing science in our communities and beyond. (more…)

An exciting, cutting-edge contribution to the scholarly record—“Electrochemically Induced Deposition (ECiD) of Lithium Phosphate and the Effect of Reaction Parameters” by Ali Amir Saleh, Louis L. De Taeye, Sai Gourang Patnaik, Genis Vanheusden, and Philippe Vereecken—features in the March issue of ECS Advances.

Tailoring ECiD processes for desired outcomes

This open-access article dives into a versatile electrochemical approach for synthesizing thin films of lithium phosphate on conductive surfaces via electrochemically induced deposition (ECiD)—a method with broad relevance for materials that are traditionally challenging to deposit electrochemically. By combining experimental investigation with numerical modelling, the authors illuminate how reaction conditions like current density, pH, and electrolyte composition shape the deposition mechanism and resulting material morphology. Their insights advance understanding of how to tailor ECiD processes for desired outcomes, knowledge that will benefit researchers across electrochemistry, energy materials, and solid state science.

Recent advances in III-nitride heterostructures continue to push the boundaries of high-frequency and high-power device performance. A new study, “Demonstrating the Effects of Growth Temperatures of Al(In)GaN Back Barrier on Transport Properties of InAlGaN/GaN Heterostructures,” takes a close look at how carefully tuning growth conditions can directly shape electronic behavior at the nanoscale.

In this article, the authors—Hoang-Tan-Ngoc Nguyen, Rahul Rai, Quoc-Huy Nguyen, Quoc Viet Hoang, Ngoc Quang Huy Dinh, Chan-Yuen Chang, Chien-Wei Chen, You-Chen Weng, Hao-Chung Kuo, Ching-Ting Lee, and Edward-Yi Chang—investigate how the growth temperature of an Al(In)GaN back barrier fabricated using metal-organic chemical vapor deposition (MOCVD) influences the structure and performance of InAlGaN/GaN heterostructures. By minimizing the temperature gap between the channel and back barrier layers, the researchers achieved highly coherent growth with smooth surfaces, sharp interfaces, and no detectable threading dislocations. These structural improvements translated into measurable performance gains: higher electron mobility, reduced sheet carrier density, and stronger electron confinement. (more…)

ECS Advances is pleased to highlight a recent article that makes an important contribution to the understanding of high-temperature electrochemical processes: “Evaluating Platinum, Gold, Glassy Carbon, and Graphite Anodes for Chlorine Evolution in Molten Calcium Chloride Salt.” Authored by Cameron Vann, Shelssie Klvacek, Carlos Mejia,  and Devin Rappleye, this work provides timely and practical insights into materials selection for chlorine evolution under extreme conditions.

The chlorine evolution reaction (CER) in molten calcium chloride (CaCl₂) carries several critical technologies, including chlorination, metal refining, rare earth processing, and the treatment and purification of used nuclear fuel. Despite its importance, long-term anode stability and performance in molten salt environments remain persistent challenges. This study directly addresses those challenges through a systematic comparison of four commonly considered anode materials: platinum, gold, glassy carbon, and graphite. (more…)

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.
