Variation of Nucleophilicity NHnA of Atoms A in Hydrides HnA with the Group and Row of A in the Periodic Table

open access: yesChemPhysChem, Volume 26, Issue 13, July 2, 2025.
Gradients of De versus electrophilicity EHX graphs for hydrogen‐bonded complexes HnA···HX give nucleophilicities of atoms A of Lewis base HnA. The dependence of nucleophilicity of hydrides HnA on their position in the periodic table is then obtained by varying the atom A down the rows within a group and across rows from group to group ...

A Thermodynamic Scale of Multiple Bonds Reducibility Based on G4 Calculations

open access: yesChemPhysChem, Volume 26, Issue 13, July 2, 2025.
An original scale for the reducibility of multiple bonds is established through G4 theoretical calculations in two steps: 1) comparing the gas heats of formation (ΔfH°) derived from G4 theoretical calculations with experimental values from NIST and ATcT, and 2) using the calculated ΔfH° (G4) to determine the hydrogenation enthalpies (ΔH2H ...

Magnetic Actuation Under DC and AC Fields of Thermoplastic Polyurethane With Strontium Hexaferrite

open access: yesAdvanced Materials Technologies, Volume 10, Issue 13, July 8, 2025.
Magnetic thermoplastic polyurethane composites with strontium hexaferrite (SrFe12O19) are produced through a solvent‐free melt‐mixing technique. These composites display a magnetomechanical actuation mechanism, being able to deform (bend and twist) through DC and AC magnetic fields, showcasing their potential as a promising material for the fabrication

Silylative Kinetic Resolution of Acyclic Secondary Benzylic Alcohols Catalyzed by Chiral Guanidine Having Axial Chirality Containing a Methoxy Group

open access: yesChinese Journal of Chemistry, Volume 43, Issue 13, Page 1553-1559, 1 July 2025.
An efficient silylative kinetic resolution of acyclic secondary benzylic alcohols was achieved using chlorosilanes and new axially chiral guanidine catalysts bearing a methoxy group. Comprehensive Summary New chiral guanidine catalysts having axial chirality containing a methoxy group were synthesized. Subsequently, their catalytic ability was examined

Advanced Stage Head and Neck Cancer Diagnosis: HEADSpAcE Consortium Health Systems Benchmarking Survey

open access: yesHead &Neck, Volume 47, Issue 7, Page 1977-1988, July 2025.
ABSTRACT Background Globally, most people with head and neck cancers (HNCs) are diagnosed with advanced‐stage disease. HNC diagnostic stage has multifactorial explanations, with the role of health system factors not yet fully investigated. Methods HNC centres (n = 18) from the HEADSpAcE Consortium were surveyed via a bespoke health system questionnaire

A systematic review and meta‐analysis of parental mentalization in fathers and mothers

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 46, Issue 4, Page 406-423, July 2025.
Abstract Despite the growing literature on parental mentalization (including measures such as mind‐mindedness, parental reflective functioning, and parental insightfulness), considerably less research on parental mentalization has been conducted with fathers than with mothers, leaving important gaps in our understanding of gender differences in the ...
