Upcycling Poly(vinyl chloride) and Polystyrene Plastics Using Photothermal Conversion.

Journal of the American Chemical Society
Poly(vinyl chloride) (PVC) and polystyrene (PS) are among the least recycled plastics. In this work, we developed a simple and novel strategy to valorize PVC and PS plastics via photothermal conversion to (1-chloroethyl)benzene, a commodity chemical with

Geography-guided industrial-level upcycling of polyethylene terephthalate plastics through alkaline seawater-based processes

Science Advances
The escalating plastic crisis can be mitigated by upgrading waste polyethylene terephthalate (PET). Leveraging the geographical advantages of offshores with established chlor-alkali industries, abundant renewable energy, and extensive seawater, we here ...

Enzymes emerge by upcycling

Nature Chemical Biology, 2018
Catalytic activity is a critical protein function, but its natural evolution has never been observed. Researchers have now revealed the mutations and biochemical mechanisms by which two ancient nonenzymatic proteins acquired catalytic activity.

Coupling Photocatalytic Reduction and Biosynthesis towards Sustainable CO2 Upcycling.

Angewandte Chemie
Upcycling carbon dioxide (CO2) into long-chain compounds has attracted considerable attention with respect to mitigating environmental problems and obtaining value-added feedstocks, but remains a great challenge. Herein, we report a tandem photocatalysis-

Upcycling of Low‐Value Cathode Materials from Spent Lithium‐Ion Battery to High‐Voltage Cathode with Ultrahigh Rate Capability and Reversibility

Advanced Energy Materials
LiMn2O4 and LiFePO4 materials are widely applied in electric vehicles and energy storage. Currently, spent LiMn2O4 and LiFePO4 materials recycling is challenged by long process, high energy consumption, and poor recycling economy due to the indispensable

Drop-Upcycling: Training Sparse Mixture of Experts with Partial Re-initialization

International Conference on Learning Representations
The Mixture of Experts (MoE) architecture reduces the training and inference cost significantly compared to a dense model of equivalent capacity. Upcycling is an approach that initializes and trains an MoE model using a pre-trained dense model.

Upcycling

2016
Persistently, we take natural resources, turn them into valued products and, after a while, consider them trash and dispose of them. A sustainable alternative to this sequence is upcycling: the perfect mix between ‘upgrading’ and ‘recycling’. To upgrade is to add value and to recycle is to reuse.

Sulfur Vacancy Boosts Light-Driven C-N Coupling in Upcycling of Polylactic Acid to Alanine.

Journal of the American Chemical Society
Photocatalytic C-N coupling of lactic acid (LA) and ammonia for alanine synthesis provides an attractive route for the upcycling of poly(lactic acid) (PLA) plastic waste.

Hochhaus Upcycled

2023
Im Stadtquartier Muthgasse befindet sich das APA Hochhaus, welches seit viele Jahren leer steht, bereits zahlreiche Besitzerwechsel hinter sich hat und dadurch ein Zeichen für schlechte Stadtentwicklung ist. Anstatt es abzureißen, wird ein Konzept entworfen, die das Hochhaus umgebaut und verbessert werden kann.
