Business Strategy and the Environment, EarlyView.ABSTRACT This study integrates multidimensional sustainability indicators into a unified assessment approach to evaluate circular strategies in agri‐food industry businesses. This methodological approach is applied to empirically examine the case of the olive oil industry's by‐product valorization.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes
ChemistryEurope, EarlyView.A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Carbon Energy, EarlyView.The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Chemistry – A European Journal, EarlyView.Key performance metrics, including hexene conversion rates and catalyst leaching, were evaluated over extended continuous operation periods. Results demonstrated that the OSN method significantly outperformed the multiphasic system, maintaining hexene conversion at 83% after 76 h compared to a decline to 72% in the multiphasic setup after 36 h ...

Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification
Chemie Ingenieur Technik, EarlyView.We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

Risk assessment of syngas pipeline leakage based on a Dynamic Bayesian Network
Emergency Management Science and TechnologyThe syngas pipeline serves as the primary carrier for syngas exported from the coal gasification furnace, is vulnerable to corrosion and erosion from the transported medium, and is prone to leakage due to long-term high-pressure operation.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...
