The Origin of Efficiency in III‐Nitride Micro‐Light‐Emitting Diodes
Advanced Science, Volume 13, Issue 25, 4 May 2026.The images show panchromatic cathodoluminescence of III‐V materials, which reveal that AlGaInP red wafers, having fewer defects, support longer carrier diffusion lengths. Meanwhile, the density of defects increases with longer emission wavelengths in the InGaN system, illustrating how generated carriers pass through the material and how defects limit ...

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 ...

Determination of refractory organic matter in marine sediments by chemical oxidation, analytical pyrolysis and solid-state 13C nuclear magnetic resonance spectroscopy [PDF]
, 2008 Seeking to quantify the amount of refractory organic matter (ROM), which includes black carbon-like material (BC), in marine sediments, we have applied a two-step procedure that consists of a chemical oxidation with sodium chlorite of the demineralized ...

Laser‐Enabled Nanopinholes for Silicon Solar Cells with Polycrystalline Si/SiOx Passivating Contacts
Solar RRL, Volume 10, Issue 8, 27 April 2026.Conductive nanoscale pinholes are created by selective heating of pyramid tips on randomly textured silicon via pulsed laser irradiation. Due to heat concentration at the pyramid tips, the dielectric passivating layer is selectively opened at the pyramid tips.

Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.Fluoroalkyl‐functionalized tin–oxo nanoclusters (N‐TOC6) enable robust pattern formation through ligand crosslinking under EUV exposure without thermal processing. Sn–F coordination mitigates the Lewis acidity of Sn centers, suppressing reactions with airborne molecules and improving post‐exposure pattern stability.
