Catalytic Conversion of Lower Olefins to Aromatics Using Zeolite‐Based Catalysts

open access: yesChemCatChem, Volume 18, Issue 9, 14 May 2026.
Zeolite‐catalyzed upgrading of light olefins (C2–C4) into benzene, toluene, and xylenes (BTX) represents a sustainable route to aromatics. This review outlines thermodynamic and mechanistic aspects, the influence of acidity and textural properties of catalysts.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS

open access: yesThe 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 ...

Rational Design of Transition‐Metal Dual‐Atom Catalysts: Exploiting Neighboring Effects for Efficient CO2 Reduction

open access: yesCarbon Neutralization, Volume 5, Issue 3, May 2026.
A dual‐atom catalyst with adjustable proximity effects is depicted, showing that variations in metal–metal interactions can modulate electronic structure, intermediate adsorption, and reaction pathways. These changes guide product selectivity in CO2 reduction and highlight design principles for efficient, tunable DAC systems.

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Alzheimer's disease and mixed pathologies as a hidden contributor to fatal hypothermia: A large‐scale forensic autopsy‐based study

open access: yesBrain Pathology, Volume 36, Issue 3, May 2026.
We investigated neuropathological manifestations of hypothermia in 168 cases. Patients aged 65 years or more constituted 80% of the total cohort. Alzheimer's disease was the most common comorbidity, affecting 40% of all patients. Abstract There is a paucity of autopsy‐based studies providing detailed neuropathological characteristics of fatal ...
