Integrated Orbitrap‐HRMS and Chemometric Profiling Reveals Metabolite Diversity and Antioxidant Signatures in Cerrado Eugenia Fruits

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Fruits from the Brazilian Cerrado, such as pitanga (Eugenia uniflora), jambolao (E. jambolana) and murta (E. punicifolia), are recognized for their nutritional and therapeutic potential, largely due to their phenolic‐rich profiles. However, systematic studies integrating high‐resolution mass spectrometry (HRMS) with chemometric tools to ...

A self-reactivated PdCu catalyst for aldehyde electro-oxidation with anodic hydrogen production

Nature Communications
The low-potential aldehyde oxidation reaction can occur at low potential (~0 VRHE) and release H2 at the anode, enabling hydrogen production with less than one-tenth of the energy consumption required for water splitting.

Beyond Beer‐Lambert Linear Regression: Multi‐Layer Modeling for Wide‐Range Concentration Quantification Using Ultraviolet‐visible Spectroscopy

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Ultraviolet–visible (UV‐Vis) spectroscopy is widely used for chemical quantification due to its simplicity and low cost; however, accurate concentration prediction becomes challenging when target concentrations span wide ranges, where the global linearity assumption of the Beer‐Lambert law often breaks down.

Extraction of Sulfachloropyridazine from Food Samples Using Cellulose: Application of Central Composite Design Approach

Analytical Science Advances, Volume 7, Issue 1, June 2026.
Functionalized cellulose–ATPE for sulfachloropyridazine extraction. ABSTRACT Sulfonamide antibiotics are among the most widely used veterinary drugs in livestock and often end up contaminating milk, which is subsequently consumed by humans. To mitigate this health hazard, cellulose and its functionalized derivatives were investigated for their ability ...

Protracted molecular dynamics and secondary structure introspection to identify dual-target inhibitors of Nipah virus exerting approved small molecules repurposing

Scientific Reports
Nipah virus (NiV), with its significantly higher mortality rate compared to COVID-19, presents a looming threat as a potential next pandemic, particularly if constant mutations of NiV increase its transmissibility and transmission.

Panel performance: Modelling variation in sensory profiling data by multiway analysis [PDF]

, 2009
Sensory profiling data is essentially three-way data where samples, attributes and assessors are the three dimensions of information. It is common practice to average over the assessors and focus the analysis on the relations between samples and sensory ...

Gas Chromatography‐Based Methods for Profiling Volatile Off‐Aroma Compounds in Grain Legumes: A Review

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

On the Foundational Arguments of Sufficient Dimension Reduction

WIREs Computational Statistics, Volume 18, Issue 2, June 2026.
Contemporary Sufficient Dimension Reduction, a versatile method for extracting material information from data, can serve as a preprocessor for classical modeling and inference, or as a standalone theory that leads directly to statistical inference. ABSTRACT Sufficient dimension reduction (SDR) refers to supervised methods of dimension reduction that ...
