Triplet Acetone Generation by Pseudoperoxidase Activity of Myoglobin: Structural Damage and Quenching. [PDF]

Luminescence
Ferrimyoglobin pseudoperoxidase activity was demonstrated during isobutyraldehyde oxidation, yielding electronically excited triplet acetone and inducing structural damage. Sorbates and 9,10‐dibromoanthracene‐2‐sulfonate exhibited protective effects.

Characterization of the Interaction of Known G‐quadruplex Ligands With a Minimal i‐Motif Structure

Chemistry – A European Journal, EarlyView.
The destabilization of a minimal i‐Motif (iM) structure by TMPyP4 is driven by ligand recognition of one terminal iM structural domain. ABSTRACT Peculiar genomic regions are prone to evolve transiently from double‐helix DNA to noncanonical secondary structures in response to physiological stress.

Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Analytical Modeling of MHD Flow over a Permeable Rotating Disk in the Presence of Soret and Dufour Effects: Entropy Analysis

Entropy, 2016
The main concern of the present article is to study steady magnetohydrodynamics (MHD) flow, heat transfer and entropy generation past a permeable rotating disk using a semi numerical/analytical method named Homotopy Analysis Method (HAM).

Exploring the Boundaries of Aromaticity in Complex Structures and Excited States Through Computational Analysis

Chemistry – A European Journal, EarlyView.
Understanding aromaticity has evolved from benzene‐centric concepts to a broad multidimensional framework spanning organic, inorganic, and excited‐state systems. This review highlights ambiguities between magnetic, electronic, geometric, and energetic descriptors, emphasizing the need for unified, multi‐criteria approaches.

Stably Embedded Minimal Hypersurfaces

, 2007
We use Schoen-Simon-Yau's curvature estimates to prove that the subfocal tubular neighborhood of a non planar minimal hypersurface with bounded second fundamental form, stably embedded in R^{n+1}, n < 5, whose radius decays sufficiently slowly can not

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Radiation Effect on MHD Blood Flow Through a Tapered Porous Stenosed Artery with Thermal and Mass Diffusion

International Journal of Applied Mechanics and Engineering, 2019
A mathematical model for MHD blood flow through a stenosed artery with Soret and Dufour effects in the presence of thermal radiation has been studied. A uniform magnetic field is applied perpendicular to the porous surface.

Rayleigh-Marangoni Instability of Binary Fluids with Small Lewis Number and Nano-Fluids in the Presence of the Soret Effect

Fluid Dynamics & Materials Processing, 2010
A general model for two-component transport phenomena applicable for both nanofluids and binary solutions is formulated. We investigate a combined long-wave Marangoni and Rayleigh instability of a quiescent state of a binary (nano-) liquid layer with a non-deformable free surface. The layer is heated from below or from above. The concentration gradient

Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand
