Li-ion and Li metal batteries are widely used for portable devices due to their high gravimetric and volumetric energy densities and cyclability. However, overcharging and extreme discharging of the battery can lead to overheating and thermal runaway, while improper use can lead to fires and explosions. The volatility and flammability of the organic solvents (ethylene carbonate/dimethyl carbonate) used as electrolytes are the major sources of these thermal stability issues. Therefore, an alternative to flammable electrolytes, room temperature ionic liquids (RTILs) electrolyte chemistry is investigated due to its high thermal and electrochemical stability. Here, the fundamental understanding of developing high temperature Liion battery materials is evaluated using electrochemistry and depth-dependent the X-ray spectroscopy techniques.

This article discusses the definition of “clean” hydrogen produced by various pathways with a focus on transitioning from color-coded definitions to one that is based on the emissions generated in its creation. Herein, we also discuss the limitations of color-coding by providing a refined critique and assessment. With increasing emphasis on decarbonization efforts and clean energy transition, clean hydrogen’s role has been recognized more than ever, from clean energy bills and roadmaps to net-zero scenarios, which necessitates a clear, unambiguous definition for clean hydrogen. This article aims to help stimulate discussions as some colors’ associations may fade in favor of carbon intensity of the hydrogen production, in light of recent developments and interests in re-categorizing hydrogen production pathways and reducing associated carbon intensity from a life-cycle perspective.

This project will address the critical bottleneck in electrochemical redox processes (i.e., decreasing cost and improving efficiency) for wastewater treatment and resource recovery by developing cost-effective and selective electrode materials that can treat or valorize ROC for safe discharge or reuse. The overarching goal is to develop an electrochemical prototype to degrade a wide range of organic contaminants, minimize electrodes’ fouling and scaling, and recover valuable resources (e.g., metals and salts), contributing to achieving “pipe parity” and “circular economy” using small-scale and modular electrochemical water treatment systems.

In this installment of the “Looking at Patent Law” series, we illustrate a high-level perspective of the impact of electrochemical science and engineering on innovation and technology development, as evidenced by inclusion within the patent literature. We searched the USPTO patent data base for the past thirty-one years using commercially available software. The search was limited to U.S. patents and included the Boolean search string was “electrochem* OR electroly*” for U.S. patents issued within the date range of 01/01/1991 to 12/31/2021. Over the past ten years “electrochemical” patents represent nearly 5% of “all” issued patents. The top assignees of the “electrochemical” patents attend and/or present at biannual ECS meetings and publish in ECS journals. Notable top inventors of “electrochemical” patents include: 1) Dr. Shumpei Yamazaki with over 800 patents, 2) Dr. Adam Heller, the inventor of the electrochemical-based glucose monitor, and 3) Dr. Esther Takeuchi, inventor of the implantable cardiac defibrillator.
在“看专利法”系列的这一部分中，我们从高层次的角度阐述了电化学科学和工程对创新和技术发展的影响，正如专利文献中所包含的那样。我们使用商业软件检索了美国专利商标局过去31年的专利数据库。检索仅限于美国专利，包括布尔搜索字符串“electrochem* OR electroly*”，用于检索日期范围为1991年1月1日至2021年12月31日的美国专利。在过去十年中，“电化学”专利占“所有”已发布专利的近5%。“电化学”专利的顶级受让人参加和/或出席两年一次的ECS会议，并在ECS期刊上发表文章。著名的“电化学”专利发明人包括:1)山崎平博士，拥有800多项专利;2)亚当·海勒博士，基于电化学的血糖监测仪的发明人;3)以斯特·竹内博士，植入式心脏除颤器的发明人。

Reactive oxygen and nitrogen species (ROS/RNS) are known to play an essential role in cell signaling, disease development and progression. The production of ROS/RNS in living cells can be induced by diacylglycerol-lactone (DAG-lactone) through activation of protein kinase C, an important therapeutic target for cancer and other diseases. In a previous report, nano-electrochemistry was performed to evaluate the production of ROS/RNS inside a human breast cell (MCF-10A) treated with DAG-lactone. Simultaneously, the formation of large intracellular vacuoles was observed using a microscope. These results suggest a possibility that the ROS/RNS were stored in the intracellular vacuoles. The experiments carried out during this summer were aimed to elucidate the relationship between the intracellular production of vesicles and ROS/RNS.
