High-performance microwave-absorbing materials (MAMs) require a precise balance between dielectric and magnetic losses to achieve optimal impedance matching. Herein, we report the synthesis of ZnFe2O4@PANI composites via a magnetic-field-aided in-situ oxidative polymerization method. Systematic characterization reveal…
ABSTRACT Chemiluminescence eliminates interference from real‐time excitation light, thereby maximizing the signal‐to‐noise ratio of imaging. However, the reported chemiluminescent scaffolds remain limited, and the development of novel and efficient chemiluminescent scaffolds is critical and urgent. Herein, we synthesi…
Abstract A series of zirconium(IV) complexes with a bis(benzylamino)-p-tert-butylcalix[4]arene ligand, LZrX2, were synthesized and structurally characterized via single-crystal X-ray diffraction and NMR. The obtained complexes proved to be unexpectedly susceptible to protonation because of the low acidity of the ligan…
This study investigates the mechanical and tribological behavior of three composites with a ZrO2 matrix stabilized with 1.75 mol% Y2O3 and containing 1 wt.% Al2O3, reinforced with TiC (A), TiC + ZrC (B), and TiC + WC + Mo2C (C). The matrix powder was synthesized by chemical coprecipitation, and the composites were con…
The precise geometric and topological mechanisms governing high-temperature and potential room-temperature superconductivity (RTS) remain obscured by the mathematical rigidity of continuous differential equations. In this paper, we operationalize the theoretical premise that superconductivity is not merely a quantum p…
The increasing demand for sustainable materials has intensified interest in converting agricultural residues into functional fillers for polymer composites. This study investigated the thermal, structural, and flammability characteristics of polypropylene (PP) composites containing untreated Canarium schweinfurthii nu…
Abstract In this work, a series of ACo2O4 (A = Mn, Ni, Zn) spinel catalysts were prepared by a sol-gel method, which were further promoted through H2/Ar plasma treatment. Activity test results have shown that the plasma-treated MnCo2O4-p exhibits excellent low-temperature activity (T90 = 218 °C). The XPS, H2-TPR, 18O2…
FINDING: The five Platonic solids are the only convex regular polyhedra, arising from constraints on vertex figures and face angles, with molecular geometry reflecting their symmetry groups. MATH: Euler's formula: V - E + F = 2. For regular polyhedra: {p,q} where p = sides per face, q = faces per vertex. Constraint: 1…
Two-dimensional (2D) MXenes have been widely recognized as an extremely promising type of transition metal carbides, nitrides, and carbonitrides as a material of high-quality sensing technologies, owing to their outstanding electrical conductivity, controllable surface chemistry, and high specific surface area as well…
The increasing environmental concern associated with non-biodegradable plastics have sparked significant interest in biodegradable alternatives such as polylactic acid (PLA), polybutylene succinate (PBS) and polybutylene adipate terephthalate (PBAT) for food packaging applications. While these polymers show potential,…
Cholesteric liquid crystals (CLCs) possess the unique ability to selectively reflect incident circularly polarized light, exhibiting tremendous potential in diverse optical applications. In this study, a trilayer composite architecture of polymer-stabilized cholesteric liquid crystals (PSCLCs) was successfully fabrica…
Abstract Uncontrolled residues of tetracycline antibiotics (TCs) in food disrupt human gut homeostasis and even trigger hepatic disorders, thereby highlighting the critical necessity for detecting trace TCs. Herein, two nitrogen-incorporated carbon nanodots (N1–36CD and N2–24CD) were prepared through a hydrothermal ro…
The modulation of ZnO physicochemical properties through Mn doping represents a promising strategy for the development of multifunctional nanomaterials with enhanced biological performance. In this study, we investigate how the nominal Mn concentration influences both the physicochemical properties and antibacterial,…
This paper develops a revised mathematical solution framework for the chemistry challenge "What reaction networks govern unwanted crosslinking and char formation during plastic upcycling?". The proposed Branching Polyolefin Deconstruction Network (BPDN) was constructed after an earlier formulation failed or remained o…
This paper develops a revised mathematical solution framework for the chemistry challenge "Discover room-temperature, ambient-pressure superconductors with reproducible evidence?". The proposed Conjunctive Superconductivity Evidence Gate (CSEG) was constructed after an earlier formulation failed or remained only parti…
Abstract Traditional actuation mechanisms for biomedical shape memory polymers exhibit prohibitive limitations, including the severe risk of localized thermal tissue necrosis, a reliance on cumbersome external triggering equipment, and the potential long-term toxicity introduced by nonbiodegradable conductive fillers.…
The heavy reliance on wood for pulp and paper production has led to a shortage of fibrous resources and accelerated deforestation. In response, non-wood alternatives have gained increasing attention; however, materials such as wheat straw pose challenges due to their high silica content. To address this issue, a combi…
Abstract Crystal structures, particularly those of oxides, are viewed as architectures composed of coordination polyhedra, such as tetrahedra, octahedra, and cuboctahedra. While this perspective has long enabled electronic tuning via elemental substitution within known frameworks, its application to the design of new…
Infection remains a major cause of implant failure, motivating the development of biodegradable metals with intrinsic antibacterial activity. This study investigated how minor silver (Ag) addition regulates the degradation and antibacterial performance of extruded Mg-2Zn-0.2Ca alloys. Adding 0.1 wt % Ag significantly…
Abstract Covalent organic frameworks (COFs) have attracted considerable attention as promising photocatalysts for hydrogen peroxide (H2O2) production. To further improve their catalytic performance, a quaternary ammonium functionality was introduced into the bipyridine units of the COF via a post-synthetic modificatio…
