An Investigation of Hyperostosis Frontalis Interna in a Modern Anatomical Body Donor Population

open access: yesClinical Anatomy, EarlyView.
ABSTRACT This research sought to examine the prevalence and severity of hyperostosis frontalis interna (HFI) in the Chicagoland anatomical body donor population. The study further aimed to elucidate potential demographic risk factors for HFI, including sex, age at death, and structural vulnerability index (SVI), as well as any common comorbidities, as ...

Elemental Analysis of Catalysts in a Fixed‐Bed Reactor by Laser‐Induced Breakdown Spectroscopy

open access: yesChemCatChem, EarlyView.
The “Elemental Composition” provides information about promoters and poisons found in heterogeneous catalysts. Access to this piece of information under reaction conditions remains yet an unsolved challenge. This work explores the potential and limitations of laser‐induced breakdown spectroscopy (LIBS) as an in situ reactor diagnostic technique ...

Application of Metal‐Organic Framework Composites

open access: yesChemistryEurope, EarlyView.
This review summarizes the applications of MOF composites in adsorption, energy storage, catalysis, biomedicine, and sensing. It also discusses the functionality of MOF composites from a dimensional perspective. Environmental issues have intensified, and demand for energy continues to grow, making it challenging for conventional materials to meet the ...

Lead‐Free (K0.5Na0.5)NbO3 Unmodified Piezoceramics: A Reduction in the Energetic Budget of Solid State Synthesis and Sintering

open access: yesChemistry–Methods, EarlyView.
The temperature of the solid‐state synthesis of pure (K0.5Na0.5)NbO3 piezo‐composition is reduced by using the niobium pentoxide reactant in the mixture of reagents after attrition milling for only 3h: a majoritarian (57 wt.% of the total Nb2O5 content) orthorhombic polymorph Pbam.

Pigment‐Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials

open access: yesChemistry–Methods, EarlyView.
A methodology has been developed to extract the colored organic fraction occluded within seashell biomineral waste. Applied to sea urchin skeletons, free polyhydroxylated naphthoquinone (PHNQ) pigments and PHNQ‐macromolecule complexes are isolated. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to
