Recyclable Plastic for the Printer

Polythioenones: a step toward a circular economy for synthetic polymers

17-Feb-2025 - The possibilities for material design and production of plastic components are being expanded through 3D printing technology. However, there is a shortage of recyclable polymers that meet the performance requirements. In the journal Angewandte Chemie, a research team has introduced a new class of ...

Sweet or Sour Natural Gas

Polyimide membranes for the purification of natural gas

26-Jun-2020 - Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be “sweetened” by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it is possible to produce ...

Pores with a Memory

Porous polymer films with shape memory

08-Feb-2018 - Whether for separation processes, photovoltaics, catalysis, or electronics, porous polymer membranes are needed in many fields. Membranes with micropores that switch between different shapes and/or sizes would expand the possibilities. Scientists have introduced a process that produces porous ...

Nanostructure boosts stability of organic thin-film transistors

16-Jan-2018 - A nanostructured gate dielectric may have addressed the most significant obstacle to expanding the use of organic semiconductors for thin-film transistors. The structure, composed of a fluoropolymer layer followed by a nanolaminate made from two metal oxide materials, serves as gate dielectric ...

Are 20 percent of materials chemistry papers wrong?

18-Dec-2017 - Can companies rely on the results of one or two scientific studies to design a new industrial process or launch a new product? In at least one area of materials chemistry, the answer may be yes -- but only 80 percent of the time. The replicability of results from scientific studies has become a ...

New 3-D printing method creates shape-shifting objects

18-Apr-2017 - A team of researchers from Georgia Institute of Technology and two other institutions has developed a new 3-D printing method to create objects that can permanently transform into a range of different shapes in response to heat. The team, which included researchers from the Singapore University ...

Low-cost technique converts bulk alloys to oxide nanowires

23-Jan-2017 - A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could open the door for a broad range of uses in lightweight structural composites, advanced sensors, electronic devices - and ...

Was the secret spice in primal gene soup a thickener?

12-Oct-2016 - The original recipe for gene soup may have been simple -- rain, a jumble of common molecules, warm sunshine, and nighttime cooling. Then add a pinch of thickener. The last ingredient may have helped gene-like strands to copy themselves in puddles for the first time ever, billions of years ago ...

Metamaterial separation proposed for chemical, biomolecular uses

07-Mar-2016 - The unique properties of metamaterials have been used to cloak objects from light, and to hide them from vibration, pressure waves and heat. Now, a Georgia Institute of Technology researcher wants to add another use for metamaterials: creating a new directional separation technique that cloaks ...

Sol-gel capacitor dielectric offers record-high energy storage

04-Aug-2015 - Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain batteries, with both a high energy density and high power density. If ...
