Non‐Destructive Analysis of Phenolic and Flavonoid Contents in Medicinal Plant Powders Using Hyperspectral Imaging and Variable Selection

open access: yesAnalytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Phenolic and flavonoid contents in medicinal plants are essential to their growth and development and provide numerous health benefits, yet their quantification using traditional wet chemistry is labor‐intensive and time‐consuming. This study utilized the combination of two benchtop hyperspectral imaging (HSI) systems, namely short‐wave ...

Distinct Epigenetic Responses to Aging and Short‐Term High‐Fat Diet in Hepatic Lipid Metabolism Genes in Male and Female Mice

open access: yesLiver International Communications, Volume 7, Issue 4, December 2026.
ABSTRACT Background and Aims Aging is associated with widespread epigenetic remodelling that contributes to metabolic alterations in the liver. High‐fat diet (HFD) represents a major environmental perturbation affecting hepatic metabolism, yet its specific impact on age‐associated epigenetic changes remains unclear.

A Cyclic {NiII8DyIII4} Cluster Where the DyIII Moments Are Organized by the Transition Metal Spins

open access: yesChemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
The synthesis, structural characterisation, and magnetic properties of a cyclic Ni8Dy4 coordination cluster are reported. Ab initio CASSCF and DFT calculations help rationalize the shape of the microSQUID hysteresis and the competing magnetic interactions within the compound. ABSTRACT A series of [Ni8Ln4(CO3)4(L)8(NO3)2(H2O)8 (MeOH)4](NO3)2 (Ln = Dy (1)

Partially Biobased Polyurethanes With Reversibly Crosslinkable Furan Units Toward Recyclable Thermosetting Textile Fibres

open access: yesChemistry – A European Journal, Volume 32, Issue 41, 3 November 2026.
A molecular design strategy combines lignin‐derived aromatic units, sugar‐derived furan groups, and flexible glycol segments to create wet‐spinnable polyurethanes. Thermally reversible Diels–Alder crosslinking chemistry enables formation of crosslinked thermosetting fibers, repeated de‐crosslinking/re‐crosslinking cycles, and tunable fiber properties ...

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,

Viability of C. neoformans in the presence of o-vanillin.

open access: yes, 2014
The fungal cells were grown in YPD media containing different concentrations of o-vanillin or fluconazole as indicated, and incubated at 30°C. Viability of the cells were determined by measuring CFUs after 2 days. Fluconazole was included as a control.
