Brain neuromodulation has revolutionized the medical treatment of neurological diseases and injuries; however, existing therapies are limited in their clinical scope of application. Most existing therapies are delivered through implanted macroelectrodes that reside either on top of or directly inside the brain. Estimates of the effective electric field spread from these devices generally span from thousands to millions of individual neurons. Unfortunately, some neurological diseases and injuries require stimulation fields of higher precision. Next-generation microneuromodulation devices (˜102 – 103 μm2 surface area) have been developed with hundreds of closely spaced channels. These devices may be able to provide electrical microstimulation in the form of biphasic, charge-balanced small amplitude square waves that provide salient, behaviorally relevant information to human subjects. However, there is a lack of knowledge incorporated into their safety and clinical use. Neuromodulation is a field of science, medicine, and bioengineering that encompasses implantable and non-implantable technologies, electrical or chemical, that act upon neural interfaces to improve life for humanity. Our research groups collaboratively investigate neuromodulation performed via electrical microstimulation. Our primary development target is brain neuromodulation. In this article we highlight the application of electrochemistry to the field of neuromodulation.

Hydrogen, which can be readily produced by electrochemical water splitting, has been hailed as one of the most promising green energy sources. In a water electrolyzer, catalysts are needed for the hydrogen evolution reaction (HER) at the cathode, which are traditionally based on platinum-based materials. Recently, carbon-based nanocomposites have emerged as viable alternatives, which are mostly prepared by pyrolysis or wet chemistry methods, which are time- and energy-consuming. We have exploited magnetic induction heating (MIH) for ultrafast and green preparation of high-performance HER electrocatalysts. A novel MIH method was developed for the ultrafast and green preparation of carbon-supported Ru NPs toward HER in alkaline media, where the size and morphology of the Ru NPs can be readily manipulated by the heating current and duration. It is expected that MIH can be exploited for the design and engineering of high-performance nanocomposite catalysts for important electrochemical energy technologies.

As climate change intensifies, weather patterns across the globe become far less patterned and more unpredictable. Instances of extreme heat, excessive rain resulting in floods, and droughts that may cause or intensify wildfires have severely stressed centralized water treatment and distribution facilities and compromised access to fresh water for many. Given the vast reserve of saltwater, desalination technologies that can separate the dissolved salts from the fresh water have become essential. Traditional desalination methods use either membrane or thermal-based technologies to separate solutes from salt water and brackish water that have typical concentrations of 35,000 and 1,000 mg/L, respectively. However, they can be unnecessarily energy-intensive for lower salinity conditions. A potential next-generation approach is desalination fuel cells. Desalination fuel cells have the capability to simultaneously desalinate water and produce energy.

Seventy-five years ago, on December 16, 1947, the transistor was invented by William Shockley, John Bardeen, and Walter Brattain at Bell Telephone Laboratories. This was a big milestone in human history as it was the origin of the field of micro/nano electronics, which is now resulting in a super-intelligent society. The technological revolution that followed the invention of the transistor is astounding and has moved mankind forward in countless ways. This paper describes the process of the technological development behind the invention of the transistor, and discusses the meaning and impact of its invention on human history.

Extreme fast charging (XFC) of lithium-ion batteries (LIBs) in 10 minutes is one of the main goals of the US Advanced Battery Consortium for low-cost, fast-charged electric vehicles by 2023. However, existing LIBs cannot achieve these XFC goals without significant capacity fade over cycling due to complex XFC degradation modes. One of the key XFC failure mechanisms is dead Li plating on the graphite anode. While numerous methods have detected Li plating, they lack three-dimensional non-invasive visualization of dead Li on graphite anodes in full cells during battery cycling. Herein, we demonstrate the viability of high-resolution (spatial resolution: 10–15 μm) neutron micro-computed tomography (μCT) for in-situ characterization of dead Li on graphite anodes (thickness: ~130 μm) in full cells containing NMC cathode, that were cycled at 1C and 6C.
