Adsorption and Sensing Behavior of Pristine, P‐Doped, and Al‐Doped Boron Nitride Nanosheets Toward Toxic Hydrogen Fluoride Gas: Insights from Density Functional Theory Analysis

ChemistryOpen, Volume 15, Issue 5, May 2026.
This study reveals how pristine, P‐doped, and Al‐doped boron nitride nanosheets interact with toxic hydrogen fluoride (HF) gas using density functional theory (DFT) simulation. Enhanced adsorption and charge transfer in doped systems highlight their potential as sensitive and selective gas sensors, providing molecular‐level insights for nanoscale ...

Pycnodysostosis With Papilledema and Isolated Low Parathyroid Hormone Levels in an Eight‐Year‐Old Girl: A Genetically Confirmed Case Report

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Pycnodysostosis is a rare autosomal recessive skeletal dysplasia resulting from pathogenic variants in the CTSK gene, which encodes cathepsin K, a lysosomal cysteine protease expressed in osteoclasts. Deficiency of this enzyme leads to defective bone resorption and generalized osteosclerosis.

Reflections of Their Homelands—Early Life Enamel Formation Disruption in Nineteenth Century Settlers of Otago, New Zealand

Journal of the Royal Society of New Zealand, Volume 56, Issue 1, February 2026.
Physiological stress during early life can impede development, and signals of this are preserved in nonremodelling tissues such as dental enamel. This article describes nonspecific stress markers in the teeth of European (n = 30) and Southern Chinese (n = 15) adult migrants to New Zealand, and colony‐born children (n = 10) interred in four historic ...

Indices for diagnosis of dental-skeletal fluorosis reported in epidemiological surveillance systems: thematic review

El flúor se encuentra en minerales y alimentos, y es adquirido a través de tratamientos odontológicos, productos de higiene y fuentes naturales. A pesar de sus beneficios para prevenir caries, el exceso de flúor es tóxico y puede causar fluorosis.

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.
