Abstract:

A study on the electrochemical reduction of acetylbenzoyl on a mercury electrode has been carried out in the pH range 0–9 in buffered aqueous solutions. The effect of pH, drop time, temperature, and acetylbenzoyl concentration on polarographic and kinetic parameters has been studied. The occurrence of adsorption phenomena is inferred from the recordings of C–E curves. Tafel slopes and reaction orders have been obtained at potentials corresponding to the foot of the wave. On the basis of these experimental data, a reaction mechanism is proposed for the zone of potentials where Tafel's law is sa

Abstract:

The authors have read many textbook formulations of the DC and AC response of an anodically dissolving metal electrode (with no extraneous cathodic reactions such as water reduction), and we believe - rightly or wrongly - that most of these miss one or more important points. Under steady state DC anodic dissolution conditions, we can assume that the net anodic current density is affected by the basic kinetic parameters of the partial reactions, and by the concentration of the product cations at the electrode. One outcome of such an assumption is that the reaction may appear to obey Tafel's law

Abstract:

This study presents a corrosion analysis of carbon steel by electrochemical polarization tests on a rotating disk electrode at several aeration and hydrodynamic conditions in solution 0.2 mol L-1 K2SO4 at pH 3. The reactions involved in the dissolution of the steel are analyzed by studying the Tafel regions of the polarization curves, confirming that the dissolved oxygen plays a predominant role in the corrosion of the metal. The corrosion rate was 35 times higher in natural aeration conditions than in the deaerated medium. Under natural aeration conditions, it is not possible to make a simple

Abstract:

Acidic corrosion in industrial environments represents a serious threat that requires an active prevention and management strategy. In this context, weak acids can create a severe corrosion environment for metallic surfaces, sometimes exceeding the severity observed in strongly acidic solutions under similar conditions. While most of the research efforts of the last decades in the field of the predictive modeling of acidic corrosion have been focused on the specific case of sweet corrosion caused by carbonic acid, the goal of this work is to describe and validate a predictive model to be used

Linear voltammetry was applied in LiF-NaF and LiF-AlF3, in the temperature range 900-1100°C. The relative stability of the metals in LiF-NaF is established.

It is key to maintain or even increase the durability of the iridium-based anodic catalyst layer while further reducing its raw metal demand.

Abstract:

Fuel cell vehicles (FCVs) emerge to be promising candidates to produce clean power for the transportation sector in order to tackle climate change issues. Although the commercialization of polymer electrolyte membrane fuel cells (PEMFCs) has progressed in the past few decades, there are still obstacles to address, including high cost and limited hydrogen infrastructure. For heavy duty transportation applications, the PEMFC durability is also not yet proven, and extrapolating from lab data to real-world field operating conditions remains a significant challenge [1].

Abstract:

Alkaline water electrolysis is one of the important methods for generating high purity hydrogen. Alkaline electrolysis, because of the possibility of using relatively inexpensive electrode materials, is more economical than hydrolysis in acidic medium; the medium is also less corrosive. The challenges in water electrolysis in general are to reduce the cost, energy consumption and maintenance, hence increase the efficiency of the overall process. An important consideration in the above is the separator between the two electrode compartments, which has to be such that it minimizes (or eliminates

Abstract:

The extension of Moore’s law remains a focal point as semiconductor manufacturers drive to advance Integrated Circuit (IC) technology by implementing new materials. Chemical Mechanical Planarization (CMP) has emerged as a critical processing step in device fabrication to keep up with these demands. However, one drawback to this process is the generation of killer defects that result from residual contamination (i.e., organic residues, abrasive particles, pad remnants, etc.) that are reliant on post-CMP (p-CMP) cleaning methods. Current Cu p-CMP cleaning methods implement the use of an industry

Abstract:

While electric power supply by renewable sources such as solar and wind has become viable for their significant cost reduction, its intermittency demands urgent development of large scale storage technologies. Although conversion of electrical energy into storable hydrogen via electrolysis of water is ideal, noble metals and their oxides are used as electrocatalysts for their activities and stabilities. Alternative electrocatalysts out of abundant elements are needed for sustainable technological development. Recently, some metal-free organic conductive polymers with hydrogen-bonding capabilit

Advancing electrochemical reactors for nutrient recovery from wastewater requires an integration of continuum modeling alongside experimental investigations to appropriately capture transport effects on electrode performance.

Abstract:

The production of green hydrogen through water electrolysis using electricity generated from renewable sources is one of the most promising strategies toward achieving a carbon-neutral economy.[1-3] Water electrolysis is an effective and well-established water splitting process consisting of two half-cell reactions, the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) at cathode and anode, respectively. Although hydrogen as the value-added product is generated at the cathode, the anodic reaction plays an important role in determining the reaction kinetics of the entire

Proton exchange membrane water electrolyzers (PEMWEs) have drawn attention among various hydrogen production technologies due to their zero-emission, high conversion efficiency, high hydrogen purity (>99.99%), and quick response under dynamic operation.1,2 With these auspicious characteristics in PEMWEs, they are believed to produce 40 % of green hydrogen by 2050 among all electrolyzer technologies. Nonetheless, many bottlenecks within PEMWEs still hinder their broader commercialization. Iridium oxide is the most widely used oxygen evolution reaction (OER) electrocatalyst at the anode. More

AbstractA simple Hamiltonian Marcus-type model for cation-coupled electron transfer reactions is introduced, and an expression for the activation energy is derived. The expression is mathematically similar to the classical Frumkin correction. The model explains how cations lower the activation energy for the Volmer reaction in alkaline media and how cations help stabilizing the first intermediate in electrochemical CO2 reduction. The second part of the paper introduces the cation effect in a more empirical way in an effective rate law and shows how coupling to local pH changes and the correspo

The Dutch poet, minister and essayist Willem Barnard (1920–2010) greatly contributed to the artistic and theological exploration of fundamental questions on sacramentality. This article concentrates on the way Barnard addresses the paradox that sacraments are human acts. It starts out from his explorations of religious drama and argues that they are in Barnards works a key to a sacramentality, in particular of the Eucharist, that is intentionally performed, embodied and experienced. Central to Barnards explorations and a stimulus for his further theological reflection is the establishment of a

Abstract:

Abstract The costs of producing electrocatalysts needed for proton exchange membrane water electrolyzers can be reduced by using less expensive metals, such as ruthenium, instead of the commercially used IrO. This reduction is needed for two reasons: 1) although South Africa has the central reserves globally, iridium is a scarce element that is mined with other platinum group metals (PGMs), and 2) iridium is 4 times more expensive in comparison to platinum. Hence, efficient bimetallic (IrM oxides where M = gold or ruthenium) electrocatalysts are needed for water splitting in acidic conditions.
