Plasma‐Induced Maskless Formation of Quasi‐Periodic Nanoripples on Polymeric Substrates

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
Reactive plasma etching is proposed for maskless, rapid, mass‐production of quasi‐periodic nanoripples formed on the area adjacent to the electrode of polymeric substrates perpendicularly placed on the electrode. To this end, a modeling framework is employed for the calculation of particle trajectories, which predicts the angular and energy ...

Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐

Lie symmetries of radiation natural convection flow past an inclined surface [PDF]

arXiv, 2011
Applying Lie symmetry method, we find the most general Lie point symmetries group of the radiation natural convection flow equation(RNC). Looking the adjoint representation of the obtained symmetry group on its Lie algebra, we will find the preliminary classification of its group-invariant solutions.

Precision 4D Printing of Multifunctional Olive Oil‐Based Acrylate Photo‐resin for Biomedical Applications

Advanced Functional Materials, Volume 35, Issue 13, March 25, 2025.
This work offers an olive oil‐based acrylate photoresin for solvent‐free, precision 4D printing of sustainable polymers. The physicochemical properties of the printed materials can be fine‐tuned by incorporation of a diluent cum comonomer acrylic acid. The resulting polymers exhibit mechanical properties similar to soft collagenous bone.

Lie symmetry analysis, explicit solutions, and conservation laws of the time-fractional Fisher equation in two-dimensional space

Journal of Ocean Engineering and Science, 2022
In these analyses, we consider the time-fractional Fisher equation in two-dimensional space. Through the use of the Riemann-Liouville derivative approach, the well-known Lie point symmetries of the utilized equation are derived.

Continuous Symmetries of Difference Equations

, 2005
Lie group theory was originally created more than 100 years ago as a tool for solving ordinary and partial differential equations. In this article we review the results of a much more recent program: the use of Lie groups to study difference equations ...

Lie point symmetry reductions of Bondi's radiating metric

Journal of Physics: Conference Series, 2007
The Lie point symmetries of the Einstein vacuum equations corresponding to the Bondi form of the line element are presented. Using these symmetries, we study reductions of the field equations, which might lead to new asymptotically flat solutions, representing gravitational waves emitted by an isolated source.

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...
