Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials.
Materials that interface with the human body, plastics to sequester carbon dioxide and other innovative and sustainable polymers will be explored in the opening session of the spring meeting of the American Chemical Society (ACS). ACS President H. N. Cheng, Ph.D., is co-sponsoring the April 5 session, which will set the stage for the meeting’s theme of “Macromolecular Chemistry: The Second Century.” ACS Spring 2021 will be held online April 5-30, with live oral technical presentations hosted April 5-16 and on-demand and networking content continuing through April 30.
Progress in the field of integrated circuits is measured by matching, exceeding, or falling behind the rate set forth by Gordon Moore, former CEO and co-founder of Intel, who said the number of electronic components, or transistors, per integrated circuit would double every year. That was more than 50 years ago, and surprisingly his prediction, now called Moore's Law, came true.
Industrializing the recycling of high performance polymers is an objective that is now crucial in preserving resources, which will require determined mobilization of the entire value chain, from organizing the collection of materials, to finalizing industrial processes and creating economic models.
Coordination polymers (CPs) composed of organic radicals have been the focus of much research attention in recent years due to their potential application to a wide variety of next-generation electronics, from more flexible devices to 'spintronics' storage of information.
In considering materials that could become the fabrics of the future, scientists have largely dismissed one widely available option: polyethylene.
Cryoprotectants are used to protect biological material during frozen storage. They have to be removed when defrosting, and how much to use and how exactly they inhibit ice recrystallisation is poorly understood. The polymer poly(vinyl)alcohol (PVA) is arguably the most potent ice recrystallisation inhibitor and researchers from the University of Warwick have unravelled how exactly it works. This newly acquired knowledge base provides novel guidelines to design the next generation of cryoprotectants
In recent years there has been an increased focus on the circular economy and a heightened demand for products made of recyclable materials, however many materials can only be recycled so many times before they begin to wear out.
TPU researchers jointly with their colleagues from foreign universities have developed a method that allows for a laser-driven integration of metals into polymers to form electrically conductive composites. The research findings are presented in Ultra-Robust Flexible Electronics by Laser-Driven Polymer-Nanomaterials Integration article Ultra-Robust Flexible Electronics by Laser-Driven Polymer-Nanomaterials Integration, published in Advanced Functional Materials academic journal (Q1, IF 16,836).
As far as green chemistry is concerned, identifying novel and lasting solutions to the material needs is one of the main targets.
