3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

The Canadian Journal of Chemical Engineering, Volume 104, Issue 5, Page 2206-2224, May 2026.
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

MICRO-PIXE FOR SINGLE CELL ANALYSIS

, 2012
The knowledge of the intracellular distribution of biological relevant metals is important to understand their mechanisms of action in cells, either for physiological, toxicological or pathological processes. However, the direct detection of trace metals

Global Model Estimates of Atmospheric Al, Ca, Fe, Si, and Ti From Dust and Non‐Dust Aerosols Informed by EMIT Surface Mineralogy and Evaluated Against Observations

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract Atmospheric deposition of micro‐nutrients like Fe has been shown to be important for ocean biogeochemistry. The largest source of atmospheric Fe and other elements (e.g., Ca, Al, Si, and Ti) is desert dust, although there are significant non‐dust sources in some regions (e.g., combustion, sea salts, volcanoes). However, past estimates of these

X‐ray Fluorescence Microscopy Computed Tomography Reveals Internal Distribution of Selenium in Hyperaccumulator Plant Seeds

Ecological Research, Volume 41, Issue 3, May 2026.
Selenium hyperaccumulators are plants able to accumulate over 1000 mg/kg in their shoots while growing in their natural environments. The distribution of selenium in the seeds of the three key hyperaccumulating species was elucidated using X‐ray fluorescence microscopy computed tomography (XFM‐CT). ABSTRACT Selenium hyperaccumulators are plants able to

Influence of Root‐Applied Glutathione on Nickel Uptake and Distribution in Brassica Roots

Ecological Research, Volume 41, Issue 3, May 2026.
This study indicates that exogenous glutathione (GSH) applied to the roots inhibits nickel (Ni) uptake and its translocation to the shoots in hydroponically grown Brassica napus. Micro‐PIXE imaging further revealed that GSH reduces Ni accumulation near the stele, indicating inhibition of Ni radial transport toward the vascular tissues.
