Theoretical and Experimental Investigations of Acetal Formation During the Oxidation of Xylose to Formic Acid Catalysed by H5PV2Mo10O40 in Methanolic‐Aqueous Solution

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
The substrate‐solvent interactions play a major role in the modified OxFA process. Herein, the formation and stability of several reaction intermediates via acetalization depending on solvent composition and reaction conditions is investigated. The BioValCat (Enhanced Biomass Valorization by Engineering of Polyoxometalate Catalysts) project aims at ...

Orthogonal Quintuple‐Stimuli Responsiveness in an Ultrastable, Ultrabright Cu16 Nanocluster via Molecular and Supramolecular Engineering

open access: yesAdvanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
Through simultaneous molecular and supramolecular engineering, an atomically precise nanocluster Cu16 with ambient ultrastability and ultrabright luminescence is constructed. Cu16 employs a dual structural/luminescent channel mechanism to achieve orthogonal responsiveness to five external stimuli, demonstrating multidimensional signalling capability ...

Targeting DNA‐LNPs to Endothelial Cells Improves Expression Magnitude, Duration, and Specificity

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Attaching antibodies against endothelial cell surface proteins redirects the delivery and expression of DNA‐lipid nanoparticles to organs of interest. Our targeted nanoparticles enable organ‐selective DNA expression in the endothelium of the lungs, brain, or spleen, providing a therapeutic platform for dozens of endothelial‐centric diseases.

Obstructive sleep apnea severity, Alzheimer's disease plasma markers, and CSF brain amyloidosis and tau pathology

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION We examined obstructive sleep apnea (OSA) severity's association with Alzheimer's disease (AD) plasma biomarkers, independent or synergistic with cerebrospinal fluid (CSF) amyloid, and as a proof of concept, whether plasma amyloid beta (Aβ)42/Aβ40 with OSA severity improves detection of amyloidosis and tau pathology.

Hypereosinophilia Associated With Antisynthetase Syndrome With Anti‐Ro52/PL12 Co‐Positivity: An Unusual Presentation

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Hypereosinophilia is uncommon in ASS and this presentation makes diagnosis more challenging. Anti‐PL12's role in the severity of ILD is controversial but its association with anti‐Ro52 seems to give a more serious disease phenotype. African ethnicity could be a negative prognostic factor, associated with lung disease severity.

UPO‐Mimetic Engineering of CYP199A4 Enables Enhanced Peroxygenase Activity via the Hydrogen Peroxide Shunt Pathway

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
P450 goes peroxide: When one base just isn’t basic enough. Engineering a second basic residue into CYP199A4T252E boosts its peroxygenase activity but also makes it sensitive to H2O2. The double mutant F182R/T252E shows increased turnover before rapidly self‐destructing, revealing the fine balance between productive peroxide activation and oxidative ...

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

open access: yesChemie Ingenieur Technik, Volume 98, Issue 3, Page 78-84, March 2026.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

Fetal Pain Perception: Legislative Assertions and Developmental Neuroscience

open access: yesAnnals of the Child Neurology Society, Volume 4, Issue 1, Page 15-28, March 2026.
ABSTRACT Background Pain perception is a conscious experience, but neither pain nor consciousness is defined in the developing human fetus. Emergent consciousness may be regarded as a phenomenon that ultimately arises from an essential minimum of functional neuronal connectivity. Proposed U.S.

Development and Validation of Nomogram‐Based Predictive Models for Severe Hypoglycemia in Adults With Type 1 Diabetes Treated With Multiple Daily Injections: The SEHYPAN Study

open access: yesDiabetes/Metabolism Research and Reviews, Volume 42, Issue 3, March 2026.
ABSTRACT Background Severe hypoglycemia is a major acute complication of type 1 diabetes (T1D) and is associated with increased morbidity, mortality, and impaired quality of life. Identifying individuals at the highest risk remains essential for optimising preventive strategies in real‐world practice.
