Chemistry – A European Journal, EarlyView.The energy level diagrams for the ν(C═O) and the δ(N─H) vibrations, resulting of combining in‐phase and out‐of‐phase modes on the basis of their local symmetries, was built by applying the exciton coupling theory to a new class of chiral macrocycles, based on the 2,5‐diaminoterephthalate scaffold.

Can ISO/IEC 17025 serve as a tool to prevent scientific fraud in chemical research laboratories?
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Scientific fraud has been documented across multiple disciplines, and chemistry is no exception. Recent studies indicate that contamination of materials, methodological errors, and unreliable data, results, or analyses account for over 25% of retracted publications.

Do CSR Committees Pay Off? Direct and Indirect Links to Financial and ESG Performance
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Corporate boards increasingly delegate sustainability oversight to dedicated CSR committees, yet evidence on whether these committees improve corporate performance remains mixed. This study argues that part of this inconsistency arises because prior research often emphasizes overall associations between CSR committees and performance without ...

A Code‐Invariant QSG–VGA Co‐Design Methodology for Compact CMOS Vector‐Sum Phase Shifters
International Journal of Circuit Theory and Applications, EarlyView.A circuit‐level co‐design methodology for compact vector‐sum phase shifters is presented, combining a code‐invariant common‐gate variable‐gain amplifier (VGA) with a resistorless quadrature signal generator (QSG). By maintaining an almost constant input resistance, explicit resistors are eliminated from the QSG.

Drosophila male genitalia rotation depends on permissive remodeling of the posterior abdomen
Developmental Dynamics, EarlyView.Abstract Background One of the most characteristic morphogenetic processes in Drosophila is the 360° rotation of the male pupal genital disc. This movement is driven by the myosin Myo1D, whose expression in the genital disc is controlled by the Hox gene Abdominal‐B (Abd‐B).
