A Novel Heterometallic Ring {Cr5Ni3} and New {Cr6Co2} and {Cr6Zn2} Rings

open access: yesChemistry – A European Journal, EarlyView.
A novel heterometallic ring containing five Cr(III) and three Ni(II) centers is reported. It forms an octagon and has a single isomer, as revealed by a combination of magnetic and EPR studies and collision‐induced dissociation mass spectrometry. ABSTRACT A new heterometallic ring, [Me4N][(Me4N)2Cr5Ni3F8(BTFB)16] (BTFB = 3,5‐bis(trifluoromethyl)benzoate)

On the Sustainability of Lithium‐Ion Battery‐Powered Electric Vehicles: Critical Review, Analysis, and Perspectives

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review and analysis evaluate the benefits of LIB‐powered EVs on emission reduction of both CO2 and air pollutants. The raw materials of LIBs face low supply risks as the cathodes switch to low‐cobalt scenarios. Proper management of EV charging can mitigate its negative impact and even contribute to the stability and resilience of the power grid ...

Multiobjective Optimization of Hydrogen‐Assisted Calophyllum inophyllum Biodiesel Operation in a Compression Ignition Engine

open access: yesEnergy Science &Engineering, EarlyView.
Tri‐fuel diesel–Calophyllum inophyllum biodiesel–hydrogen operation was tested over 96 points in a diesel engine. Eight performance and emission metrics feed a preference‐agnostic Bootstrapped Empirical Multiobjective Ranking and Selection methodology, revealing load‐blend‐hydrogen windows that increase efficiency, restrain smoke, and expose NOx trade ...

Waste to Hydrogen: Transforming Food Waste Into Biohythane (Bio‐H2 + Bio‐CH4) in a Two‐Stage Reactor With the Aid of a Metal‐Ion Catalyst

open access: yesEnergy Science &Engineering, EarlyView.
This study demonstrates a two‐stage catalytic bioreactor system that converts real food waste into high‐purity biohydrogen and biohythane. In Stage‐1, an enriched Clostridium thermocellum culture combined with Ni2+─Fe2+ bimetallic catalysis enhances hydrolysis efficiency and hydrogenase activity, resulting in a 77% increase in H2 yield and 75.8% purity

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Chemical Composition, Amino Acids, Phenolic Profiles and Bioavailability of Minerals in Livingstone Potato (Plectranthus esculentus) as Affected by Different Processing Techniques

open access: yesFood Chemistry International, EarlyView.
Boiling retained the nutrients and polyphenol compounds in Plectranthus esculentus tubers better than frying or roasting. A bioavailability study showed that the phytates and oxalates in the tuber may not affect the bioavailabilities of calcium, zinc, or iron in Plectranthus esculentus tubers when eaten.
