From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

open access: yesCarbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%

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

Bismuth Chalcogenide‐Based Photocatalysts for Nitrogen Reduction: Recent Progress and Prospects

open access: yesChemistry – A European Journal, EarlyView.
Bismuth chalcogenides emerge as promising visible‐light photocatalysts for sustainable ammonia synthesis, driven by tunable electronic structures and strong N2 activation. Recent advances reveal how defects, doping and heterojunction design synergistically enhance charge separation and reactivity. Key challenges and future directions highlight pathways

Infrared Irradiation‐Assisted Pd‐Catalyzed C(sp3)─H Arylation and Tandem Cyclization of Ortho‐Tolualdehydes

open access: yesChemistry – A European Journal, EarlyView.
A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.
