Book Description
Sean Ashton's doctoral thesis, which he finished at the Technical University in Munich, describes the challenge of constructing a Differential Electrochemical Mass Spectrometer instrument (DEMS). DEMS combines an electrochemical cell with mass spectrometry via a membrane interface, allowing gaseous and volatile electrochemical reaction species to be monitored online. The thesis carefully introduces the fuel cell electrocatalyst development concerns before reviewing the pertinent literature on DEMS. This is followed by the presentation and discussion of the new extended design, including a thorough characterization of the instrument. The capabilities of the new setup are demonstrated in two research studies: The methanol oxidation reaction on Pt and PtRu catalysts, and the electrochemical corrosion of fuel cell catalyst supports. Despite both topics having long since been studied, new insights can be obtained through careful investigations with the new DEMS instrument that are of great, general interest. The thesis and the instrument thus show the way for future investigations in the field.

Book Description
There is a wide consensus that furfural, a renewable commodity currently obtained from lignocellulosic agro-residues with a production volume of around 300 kTon per year, is a key feedstock for leveraging lignocellulosic residues in future biorefineries. Several chemicals are already being manufactured from furfural due to its advantageous production cost. Furthermore, a vast number of others are also technically viable, to produce from oil.This book compiles the vast existing information into relevant stages of transformations of furfural as renewable chemicals, biofuels and bioresins focusing on the relevant chemical and engineering aspects of processes to obtain them, including reactors and catalysis. It offers essential information for improving the economic and environmental viability of current commercial applications and upcoming future applications.It should be of particular interests to graduate and advanced undergraduate students, as well as, engineers and academic researchers alike who are working in the field.

Book Description
This book honors Professor. John O’M. Bockris, presenting authoritative reviews on some of the subjects to which he made significant contributions – i.e., electrocatalysis, fuel cells, electrochemical theory, electrochemistry of single crystals, in situ techniques, rechargeable batteries, passivity, and solar-fuels – and revealing the roles of electrochemical science and technology in achieving a sustainable society. Electrochemistry has long been an object of study and is now growing in importance, not only because of its fundamental scientific interest but also because of the central role it is expected to play in a future sustainable society. Professor John O’M. Bockris contributed greatly to various aspects of fundamental and applied electrochemistry – such as the structure of the double layer, kinetics and mechanism of the electrochemistry of hydrogen and oxygen, electrocatalysis, adsorption and electrochemical oxidation of small organic molecules, fuel cells, electrocrystallization, theoretical electrochemistry, new methods, photoelectrochemistry, bioelectrochemistry, corrosion and passivity, hydrogen in metals, ionic solutions and ionic liquids, and molten silicates and glasses, as well as socio-economic issues such as the hydrogen economy – for over half a century from 1945 until his retirement in 1997.

Book Description
Electrochemical surface science (EC-SS) is the natural advancement of traditional surface science (where gas–vacuum/solid interfaces are studied) to liquid (solution)/electrified solid interfaces. Such a merging between two different disciplines—i.e., surface science (SS) and electrochemistry—officially advanced ca. three decades ago. The main characteristic of EC-SS versus electrochemistry is the reductionist approach undertaken, inherited from SS and aiming to understand the microscopic processes occurring at electrodes on the atomic level. A few of the exemplary keystone tools of EC-SS include EC-scanning probe microscopies, operando and in situ spectroscopies and electron microscopies, and differential EC mass spectrometry (DEMS). EC-SS indirectly (and often unconsciously) receives a great boost from the requirement for rational design of energy conversion and storage devices for the next generation of energetic landscapes. As a matter of fact, the number of material science groups deeply involved in such a challenging field has tremendously expanded and, within such a panorama, EC and SS investigations are intimately combined in a huge number of papers. The aim of this Special Issue is to offer an open access forum where researchers in the field of electrochemistry, surface science, and materials science could outline the great advances that can be reached by exploiting EC-SS approaches. Papers addressing both the basic science and more applied issues in the field of EC-SS and energy conversion and storage materials have been published in this Special Issue.

Book Description
This overview of diffusion and separation processes brings unsurpassed, engaging clarity to this complex topic. Diffusion is a key part of the undergraduate chemical engineering curriculum and at the core of understanding chemical purification and reaction engineering. This spontaneous mixing process is also central to our daily lives, with importance in phenomena as diverse as the dispersal of pollutants to digestion in the small intestine. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support through worked examples and a range of student questions. It also takes the reader right through to the cutting edge of our understanding, and the new examples in this third edition will appeal to professional scientists and engineers. Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.

Book Description
Electrochemistry is an old branch of physical chemistry. Due to the development of surface sensitive techniques, and a technological interest in fuel cells and batteries, it has recently undergone a rapid development. This textbook treats the field from a modern, atomistic point of view while integrating the older, macroscopic concepts. The increasing role of theory is reflected in the presentation of the basic ideas in a way that should appeal to experimentalists and theorists alike. Special care is taken to make the subject comprehensible to scientists from neighboring disciplines, especially from surface science. The book is suitable for an advanced course at the master or Ph.D. level, but should also be useful for practicing electrochemists, as well as to any scientist who wants to understand modern electrochemistry.
