Integrated Multispectroscopic Identification of Organophosphorus and Triazine Pesticide Mixtures via DFT–Spectroscopy‐Integrated Identification Method (D‐SIIM)

Analysis &Sensing, Volume 6, Issue 6, November 2026.
Identifying unknown chemicals in mixtures is limited by the reference libraries available. D‐SIIM instead cross‐validates experimental IR, Raman, and NMR spectra against DFT predictions, resolving all components of pesticide mixtures containing up to four multiring organophosphorus and triazine compounds including one for which GC–MS screening proved ...

An In‐Situ (Electro)Polymerized Itaconic Acid Coating on LiFePO 4 ${\text{LiFePO}}_{4}$ Cathodes for High Performance Lithium‐Ion Batteries

Battery Energy, Volume 5, Issue 6, November 2026.
An in‐situ polymerized itaconic acid coating enables LFP to reversibly store two Li + ${\text{Li}}^{+}$ per monomer, delivering 227 mAh g − 1 ${\text{g}}^{-1}$, 3C fast charging, and 99.99% capacity retention. This approach enhances Li + ${\text{Li}}^{+}$ transport and suppresses interfacial degradation, enabling higher‐energy and higher‐power LFP ...

Bio‐Inspired Coordination‐Engineered Fe Nanozymes on Zeolite Y for Selective Methane‐to‐Methanol Conversion

ChemCatChem, Volume 18, Issue 21, 12 November 2026.
Engineering the Fe coordination environment using bio‐inspired amino‐acid ligands within a zeolite Y framework promotes selective methane‐to‐methanol conversion under mild reaction conditions. ABSTRACT The direct conversion of methane to methanol remains a long‐standing catalytic challenge due to the inertness of C─H bond and the susceptibility of ...

Microwave‐Assisted Subcritical Water Extraction Method for the Optimized Isolation of Cellulose From Residual Soybean Hulls

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
Almost pure cellulose was extracted from soybean hulls by microwave‐assisted alkaline treatment (MW‐NaOH) and characterized. The microwave‐assisted subcritical water extraction (MASWE) of waste biomass falls within the circular economy approach, promotes sustainability, and reduces both treatment times and the use of harsh chemicals.

Zea mays Drought‐Overly Sensitive1/TUBA4 Is Wilty3, and Transcriptome Co‐Expression Analysis of Shoot Meristem Mutant Tissues Reveals Wilty2/TUB6:Wi3 Interactions Associated With Stem Vascular Bundle Development

Plant Direct, Volume 10, Issue 9, September 2026.
ABSTRACT Plant vasculature is essential for the transport of water, nutrients, and signaling molecules across organs, while also providing critical mechanical support for growth and development. Disruptions in vascular bundle formation can therefore lead to severe physiological and developmental defects.
