Plan Ahead to Buy Lab Equipment

We live in a world of instant gratification. Whether it’s streaming video from Netflix, food from Doordash, or next-day delivery from Amazon, we can have it with the click of a button. And in large part, scientific equipment suppliers are keeping up. From online portals generating fast purchase orders, to maintaining sufficient inventory, scientific equipment suppliers are meeting the needs of research scientists. However, as I mentioned briefly in an earlier ECS Blog post, COVID has affected the global supply chain, and its impact has trickled down to scientific equipment suppliers.

Most news headlines reflect the microchip shortage and its impact on the automobile industry. However, the microchip supply is not the only culprit. Automobile manufacturers grew accustomed to receiving parts quickly. As a result, they never kept extra chips in stock. Why keep additional inventory when it could be delivered at a moment’s notice? While it is undoubtedly a more economical and efficient system, its a vulnerability when your supplier can’t deliver on time. Having spare equipment to do your work is a lesson I learned early on when I was a graduate student. (more…)

Our world has no shortage of problems to solve. We now stand at a critical juncture for global action to address our most pressing challenges; from the COVID pandemic to climate change and so much more.

IBM has long recognized the urgency to find more sustainable solutions to tackle these problems (The Urgency of Science). For the first time in history we have the right tools at our disposable to do so. AI (artificial intelligence)—combined with advanced computing and access to enormous volumes of data via a secure and open hybrid cloud—can significantly accelerate the process of scientific discovery and the creation of more sustainable materials for use across a broad range of industries, including energy and batteries.

Guest blog by Sujan Shrestha, PhD, Applications Engineer, Admiral Instruments

This is a guide for electrochemists interested in understanding and validating the DC accuracy of their potentiostats. To begin, it’s important to understand how to properly interpret the specifications of the potentiostat to calculate the expected accuracy of current and voltage measurements. Keep in mind that accuracy, precision, etc., also depend on the device under test (DUT). A reliable measurement can’t be obtained from a DUT whose electrochemical properties are in constant flux.

Electrochemistry in Orbit

Guest blog by Dr. Alyson Lanciki, Scientific Editor, Metrohm International

For over twenty years now, there has been continuous human occupation off our planet.

The International Space Station (ISS), launched in 1998, is a modular satellite in low orbit around the Earth, which is visible even with the naked eye.

In October, NASA launched an Antares rocket carrying a Cygnus resupply ship. This cargo ship carried an experimental system on board used to study the oxidation of ammonia under microgravity conditions to convert urine into water on the ISS. Improving this waste management system has far-reaching repercussions for longer exploratory missions where the weight of the payload must be optimized with the amount of water needed (which is heavy) to sustain life during the trip. Given the limited resources aboard a spaceship, the recovery of water from all processes is of great importance. (more…)

Logistics may not be top-of-mind when thinking about electrochemical and solid state manufacturing processes, but one failed shipment can throw an entire production schedule off target. Specialty chemicals, such as atomic layer deposition (ALD) precursors for the manufacture of thin films, are considered hazardous materials (hazmat) and therefore require special care and preparation for transportation.

Introduction

Electrochemical investigations are a very current topic in research. In recent times advancement in technology and industry results in a world-wide increasing energy consumption. A future requirement to face this trend is the development of high capacity and as well low weight rechargeable batteries for energy storage. Therefore studies of electrolyte systems or electrode surfaces are of great importance for possible further improvements.

Also in other fields, like biochemistry or catalysis, electrochemistry is of great benefit to get access to information of molecules, depending on an applied electrochemical potential. For example of the redox-active center in biomolecules [1], the reaction behavior of catalysts or the formation of carbon oxides during alcohol oxidation.

Guest post by: Sheela Berchmans, chief scientist at the CSIR-Central Electrochemical Research Institute

Sheela Berchmans has been an ECS member since 2012 and member of the Organic and Biologic Division and India Section since 2019. Berchmans’ areas of expertise include microbial fuel cells, nanomaterials for sensor applications, bio-assisted synthesis of metal nanoparticles, and electrocatalysis. Read her past work, available now in the ECS Digital Library.

Follow the latest research on electrocatalysis at the 235th ECS Meeting taking place on May 26-30, 2019 in Dallas, TX.

Electrocatalysis assumes a special importance as the applied potential at the electrified interface provides a tunable ∆G to the rate component. ∆G consists of a chemical and a electrochemical component (e-∆G0/RT e-F∆/RT), where the electrochemical component provides a leverage to control the rate of reaction. For simple nonbonding reactions, the rate of the reaction can be expressed as a function of work function of the metal catalyst. However, when bonding reactions are concerned, the adsorption of the reactants at the electrode surface determines the rate of the reaction. For eg, we take into consideration, Hydrogen evolution reaction, (HER) a typical prototype of electrochemical reaction.

The following reaction steps determine the rate of the reaction. The first step involves the proton discharge on the electro catalyst (Volmer reaction) which desorbs either through an electrochemical desorption (Heyrovsky reaction) or chemical desorption from the electrode surface as H2 gas. (2nd and 3rd steps) This reaction is known to be highly exothermic in nature.
