The green synthesis of copper nanoparticles (CuNPs) using plant extracts has emerged as an eco-friendly, cost-effective, and sustainable alternative to conventional chemical and physical synthesis methods. In the present study, copper nanoparticles were successfully fabricated using Saraca asoca leaf extract, which se…
Аннотация Этап 16 синтезирует цикл Этапов 0–15 в единую конструктивную картину гравитации и чёрных дыр. Гравитация — бесщелевой спин-2 граничный сектор единой меры μG; кривизна — уравнение состояния голографического экрана (δSscreen[h]=δSmatter при тождестве Sscreen=3ℓ/(2G)); искривление времени — замедление скорости…
Thiophene plays a fundamental role in the development of semiconducting materials for organic electronics. In this work, we introduce a novel class of thiophene-based compounds, namely thienobelts, which are obtained by wrapping up linear thienoacenes into belt-shaped structures. Ab-initio calculations are used to pro…
QDB: A Quantum-Inspired Deductive Database and Discrete Hamiltonian Optimization Engine for Stateful Retrieval-Augmented Generation Abstract: QDB (qdb-ai) is an open-source, discrete optimization retrieval engine designed for multi-hop reasoning, temporal graph validation, and constraint-satisfying context synthesis i…
ABSTRACT Covalent functionalization is requisite to enhancing/inducing the luminescent and chiroptical properties of oligo‐aromatic compounds, owing to their rigid framework and strong aggregation characters. Here we report that linear aromatic oligomers display intense PL, CD, and CPL properties upon encapsulation by…
DEU: Hier wird in Kurzform die chemische Synthese von Zirconium aus Feststoffgettern, aus z.B. Hochdruck-Natriumdampflampen und Kathodenstrahlröhren, dargestellt. Dabei wird das Übergangsmetall im Rahmen des Urban Mining erzeugt. Diese Arbeit stellt ein noch laufendes Projekt dar. Änderungen sind also vorbehalten. All…
AISI 1045 steel is widely used in mechanical components subjected to wear, where surface performance is critical for service life. This study investigates the effect of plasma nitriding temperature on the tribological behavior and surface integrity of AISI 1045 steel. Samples were nitrided at 400°C and 450°C and chara…
ABSTRACT Pressure‐induced emission enhancement (PIEE) in organic luminescent aggregates has attracted considerable attention due to its potential applications in the field of optoelectronics. However, studies on pressure‐induced fluorescence enhancement in pyrene‐centered systems have been limited, and the underlying…

In the present study, green synthesis of CuO nanoparticles (CuO NPs), NiO nanoparticles (NiO NPs) and CuO–NiO nanocomposites were prepared using the extract of Raphia hookeri seed (RHS) using hydrothermal method for electrochemical energy storage applications is reported. The RHS was extracted for their phytochemical…
ABSTRACT Mechanical recycling of mixed post‐consumer apolar/polar polymers, due to their mis‐matched polarity and inherent immiscibility, is typically a downcycling process yielding brittle materials. An emerging method that can enhance recycling of such mixtures into dynamically crosslinked, high‐performance thermose…
This repository contains the authoritative "Zero-Trust" pedagogical corpus and the corresponding ab initio Python execution suite for the Geometric Resonance Quantum Architecture (G3 Q-Lab). The architecture harnesses aperiodic spatial translational symmetry breaking (Vogel phyllotaxis) to achieve absolute Many-Body L…
BaTiO 3 –BaO–B 2 O 3 –Bi 2 O 3 (BBB) glass composites were investigated to clarify how BBB content and sintering route control low-temperature densification, pore evolution, glass-derived phase redistribution, and crystalline phase development. Densification was assessed using 15 and 30 wt% BBB glass with pressureless…
ABSTRACT Photocatalytic O 2 reduction to H 2 O 2 offers a sustainable route for green H 2 O 2 production. However, the rapid and scalable preparation of efficient organic polymer photocatalysts remains challenging. Herein, we report a sonochemical strategy for the gram‐scale synthesis of two novel benzodifuran‐based c…
In this work, the development of a novel fluorescent spherical ensemble composed of encapsulated anthraquinone derivative ( AQG ) in micelles of Pluronic F-127 (PF-127) in aqueous solution has been presented and demonstrated its application for the selective sensing of Allura Red and Fe 3+ ions. The formation of the A…
ABSTRACT Terahertz (THz) vortices field carrying orbital angular momentum play a vital role in high‐capacity wireless communication. However, most existing devices remain a challenge in multi‐channel multiplexing, broadband operating frequency, and active capability. Here, a rotatable broadband THz vortex generator wi…
To investigate the hot deformation behavior and hot‐working window of 00Cr18Mn21Mo2Ni4N austenitic stainless steel, isothermal compression tests were performed at 900–1200 °C and strain rates of 0.01–10 s −1 . Arrhenius‐type, physics‐based, and GA‐BPNN constitutive descriptions were evaluated to obtain a reliable flow…

This monograph systematically establishes a complete mathematical theory of a new kind of number — the "Spiral Number." Starting from the standard imaginary unit i^2 = -1, the work proposes the generalized imaginary unit axiom i_f^2 = -f(N), and proves that under the requirement of scale self-similarity, the positive…
