Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from discarded plastics.
At the Laboratory of Cluster Catalysis at St Petersburg University, scientists have produced polymers from biomass. The new polymers are different from others in that they can be recycled in a simple way.
Glass is ubiquitous, from high-tech products in the fields of optics, telecommunications, chemistry and medicine to everyday objects such as bottles and windows. However, shaping glass is mainly based on processes such as melting, grinding or etching.
Fabrication of 3D freeform structures of thermoplastics involving overhang (non-anchored) structures is successfully showcased by fused deposition modeling (FDM) and direct ink writing (DIW), yet limited in terms of applicable materials and conditions of printing.
Membranes that allow certain molecules to quickly pass through while blocking others are key enablers for energy technologies from batteries and fuel cells to resource refinement and water purification.
Organic solar cell (OSC) is one of the most important green energy technologies. The photovoltaic efficiencies of OSCs are closely related to the photoactive layers, which are prepared by blending electron donor and acceptor materials.
On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomaterials derived from graphene, have been widely studied due to their tunable electronic properties and potential applications in semiconductor devices, such as field-effect transistors and spintronics.
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.
