Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

open access: yesCarbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular

Boosting Bifacial Output Power of Ag‐CIGS Solar Cells by Optimizing ITO Back‐Contact Thickness for Tandem Applications

open access: yesCarbon Energy, EarlyView.
Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

Substituent‐Dependent SERS Kinetics of Citrate‐Stabilized Gold Nanoparticles: Balancing Hotspot Formation and Colloidal Flocculation

open access: yesChemistry – A European Journal, EarlyView.
Reporter chemistry controls the operational window of liquid‐phase SERS. Para‐substituted benzenethiols induce distinct AuNPs colloidal regimes, ranging from delayed but stable hotspot formation to rapid flocculation‐dominated signal decay. The balance between SERS‐active‐state formation and colloidal loss defines whether a reporter provides reliable ...

Anion‐Selective Channels Formed by Synthetic 13‐Mer Chimeric α ‐Peptide‐Oligourea Foldamers

open access: yesChemistry – A European Journal, EarlyView.
Synthetic 13‐mer α‐peptide‐oligourea chimeric foldamers self‐assemble into supramolecular ion channels, demonstrating high ion transport activity with distinct anion selectivity in lipid membranes. This study supports the design of bioinspired functional foldamer‐based channels for synthetic ion transport applications.
