"The Journal of Materials Research is proud to announce the 2019 Gordon E. Pike JMR Paper of the Year Award. This award recognizes excellence in advancing materials knowledge through written scholarship. This year’s honors go to a team of researchers from China and the US for their report on a new form of flexible and rechargeable supercapacitor wire, which was published in the September 14, 2019 issue of Journal of Materials Research. With the rapid growth of portable and wearable electronics, researchers face many important challenges. They’re tasked with fabricating devices that are smaller, lighter, and more flexible than ever—all while delivering the same or higher levels of performance. Wire-shaped supercapacitors are among the most promising technologies developed to address these challenges. These flexible devices store and deliver energy in the form of tightly wound fibers of electrochemically active materials, such as carbon nanotubes..."

Electrochemistry has been undergoing significant transformations in the last few decades. It is now the province of academics interested only in measuring thermodynamic properties of solutions and of industrialists using electrolysis or manufacturing batteries, with a huge gap between them. It has become clear that these, apparently distinct subjects, alongside others, have a common ground and that they have grown towards each other, particularly as a result of research into the rates of electrochemical processes. Such evolution is due to a number of factors, and offers the possibility of carrying out reproducible, dynamic experiments under an ever-increasing variety of conditions with reliable and sensitive instrumentation. This has enabled many studies of a fundamental and applied nature, to be carried out.

Electrochemistry: Electroplating
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

The aim of this lesson is to introduce the concepts of Electrochemistry and Electroplating and to present their applications in our daily lives. Students are encouraged to construct their knowledge of Electroplating through brainstorming sessions, experiments and discussions. This video lesson presents a series of stories related to Electroplating and begins with a story about house gates as an example of the common items related to the Electroplating topic. Prerequisites for this lesson are knowledge of the basic concepts of electrolysis and chemical equations. The lesson will take about 60 minutes to complete, but you may want to divide the lesson into two classes if the activities require more time.

General Chemistry: Principles, Patterns, and Applications

Rating
0.0 stars

The overall goal of the authors with General Chemistry: Principles, Patterns, and Applications was to produce a text that introduces the students to the relevance and excitement of chemistry.Although much of first-year chemistry is taught as a service course, Bruce and Patricia feel there is no reason that the intrinsic excitement and potential of chemistry cannot be the focal point of the text and the course. So, they emphasize the positive aspects of chemistry and its relationship to studentsŐ lives, which requires bringing in applications early and often. In addition, the authors feel that many first year chemistry students have an enthusiasm for biologically and medically relevant topics, so they use an integrated approach in their text that includes explicit discussions of biological and environmental applications of chemistry.

"Dr. Dey and his team from India have found a rather extraordinary use for an otherwise ordinary material. They’ve developed a supercapacitor capable of storing nearly one-third as much energy as an alkaline battery using peanut shells. A much cheaper and safer alternative to the toxic materials found in most energy storage devices, peanut shells could be a welcome ingredient that powers our increasingly electronic world. Peanut shells aren’t inherently good at storing charge. But locked inside their complex carbon-based structure is the potential to extract a valuable “wonder material” that is: graphene. To do that, the research team used common methods for obtaining graphene from biomass. They crushed and carbonized the shells in the lab—but then added two important steps. First, the team blasted their blackened peanut-shell powder with ultrasound waves. Much like the peanut, graphene is best when peeled..."

"Melanin is a versatile molecule. Not only is it responsible for giving us our UV-blocking complexion. At the cellular level, it gobbles up harmful radicals that lead to diseases such as cancer and Parkinson's. But that's only the beginning. Over the past decade, researchers have focused on what might be melanin's most promising talent yet discovered: the ability to conduct electricity. That's important, because if we fancy a future where environmentally benign electronics help us fight disease, monitor our health, and store energy, we’re going to need biofriendly materials. And what better material for the job than one made right in-house. This is melanin in its most common form. When it comes to electrical charge, melanin acts as a sort of bank: always ready to lend out or take electrons, depending on the environment. Chained together, as they naturally tend to do, melanin molecules can shuffle electrons and surrounding ions end to end. The result is an all-natural electrode material..."
