Green synthesis offers a sustainable approach to nanoparticle manufacturing using plant-derived phytochemicals as natural reducing and capping agents. Herein, iron oxide nanoparticles (IONPs) biosynthesis was performed using Phyllanthus emblica extract at pH conditions (6, 9 and 12), indicating the significant role of…
We use femtosecond optical spectroscopy to study the evolution of coherent order-parameter dynamics in the prototypical charge-density-wave (CDW) system CeTe3 under hydrostatic pressure. The CDW transition temperature decreases from approximately 570 K at ambient pressure to near room temperature at approximately 6 GP…
Both carbon nanotubes (CNTs) and graphene have been called two of the most eye-catching nanofillers to synthesize advanced polymer nanocomposites, thanks to their outstanding structural, mechanical, thermal and electrical properties. Both the synthesis techniques and intrinsic characteristics of graphene and CNT-reinf…
Symmetry is a foundational concept in mathematics and physics, traditionally studied through group actions on spaces or objects. This paper proposes a unifying framework called the Universal Symmetry Hierarchy that extends the conventional notion of symmetry to multiple layers. We introduce the concept of Symmetry of…

This paper provides a novel reinterpretation of the inherent imbalance between additive and multiplicative structureswithin the ABC Conjecture (Oesterl´e–Masser Conjecture) through the lens of 2-Dimensional Square Symmetry. We proposethat the continuous scale transformation via the “Theta-link” (Θ-link) in Shinichi Mo…
This manuscript introduces the concept of a Universal Invariant Space, a mathematical framework in which every mathematical object is assigned a unique invariant signature. The construction of the Universal Invariant Algebra follows from these signatures, providing a systematic means to compare and classify objects ac…
This study investigated the effect of fast multiple rotation rolling (FMRR) rotational speed on the microstructure, mechanical properties, and in vitro corrosion behaviour of TiO₂-reinforced AZ91 magnesium composite coatings produced by friction surfacing. The coatings were subjected to FMRR at 1000, 1300, and 1600 rp…
This paper explores the concept of computational phase transitions, focusing on the abrupt shifts in algorithmic behavior triggered by changes in computational parameters. Unlike traditional phase transitions in physics, these transitions occur within the realm of computation, often manifesting as unexpected changes i…
In magnetic alloys or hybrid systems formed by molecular magnets coupled to a magnetic substrate, the exchange interaction leads to fast spin dynamics after excitation. We investigate the electronic charge and spin dynamics due to the exchange interaction in a two-sublattice system with antiferromagnetic coupling. We…
The physical properties of hydrogen-bonded systems spanning zero to three dimensions—covering low-dimensional ices, bulk liquid water and biological hydration layers—are characterized by disjoint theoretical formalisms, without a consistent quantitative analytical toolkit. This work constructs an axiomatic Topological…

Symmetry is a cornerstone of modern mathematics and physics, yet conventional treatments typically regard symmetry as a static property of a single configuration or structure. This paper introduces a new perspective, Recursive Symmetry Theory, which treats symmetry as an operation that can be applied repeatedly to gen…
Transition metal dichalcogenides (TMDCs) have garnered considerable interest as a class of layered materials with semiconducting bandgaps in the visible to near infrared. Their weak interlayer van der Waals interactions allow for layer-by-layer mechanical exfoliation down to the monolayer, making them useful in flexib…
In deep-water environments, the coupled effects of hydrostatic pressure, explosion-induced shock waves, and bubble pulsation can produce complex nonlinear dynamic responses and instability in stiffened cylindrical shells. Clarifying these response mechanisms is critical for the safety assessment and blast-resistant de…
Jahn–Teller (JT) distortions are a key driver of physical properties in many correlated oxide materials. Cooperative JT distortions, in which long-range orbital order reduces the symmetry of the average structure, are common in JT-distorted materials at low temperatures. This long-range order will often melt on heatin…
The concept of a phase space is central to the study of dynamical systems, providing a geometric arena where states evolve under the influence of a governing law. This paper introduces an analogous construction for the realm of mathematical structures themselves, giving rise to the so‑called Mathematical Structural Ph…
This paper explores the fundamental question of how much historical information is necessary for accurate prediction. We investigate whether predicting future states solely based on the current state [P(x_t)] is sufficient, or if incorporating past states [P(x_t, x_{t-1}, ..., x_0)] is required. We introduce a key con…
В работе проведена сравнительная оценка эффективности трёх металлоорганических катализаторов — 2-этилгексаноата олова(II) (ЭГО), 2-этилгексаноата висмута(III) (CAT 22) и неодеканоата висмута(III) (CAT 20A) — при формировании остеопластических композитов на основе гидроксилсодержащего силоксанового каучука СКТН-Г и аэр…
ABSTRACT Broadband epsilon‐near‐zero (ENZ) materials are crucial for 6G (sixth generation mobile networks) signal stability, biochemical sensor accuracy, and intelligent weapon systems. Here, the ultrathin ( d ∼10 µm) 2D metafilms achieving low‐frequency ultra‐broadband ENZ (10 kHz–1 MHz, d / λ ∼10 −10 ) are construct…
