Vanadium dioxide (VO2), a typical thermochromic material, undergoes a metal–semiconductor transition (MST) near 68 °C, accompanied by lattice distortion and band structure reconstruction, making it an ideal material for smart window applications. However, VO2 faces several bottlenecks that limit its engineering applic…
Corrosion inhibition of 316 L stainless steel in 1.0 M hydrochloric acid by 2,5,7-triphenyl-1,2,4-triazolo[1,5-a]pyrimidine (TPTP) was evaluated using weight-loss measurements, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarisation (PDP). The effect of inhibitor concentration was examined over…
Abstract Anthropogenic methane emissions from landfill sites and coal mines with low local concentrations (<5000 ppm) are a critical factor in climate change, and the conversion of such low concentrations of methane has been widely regarded as a thorny issue in catalysis while being pivotal for a sustainable society.…
We formulate and test a deliberately conservative common-origin candidate for the Helix–LightVortex (HLV) programme, starting from one six-dimensional parent lattice and asking whether prospectively frozen layered cut-and-project rules can generate both a finite three-dimensional carrier and intrinsic transport struct…
В работе исследованы реологические свойства импортных пластичных смазочных материалов (ПС) марок Shell Gadus S2 V220-2 и Renolit-speed-2 в зависимости от концентрации присадки Росойл-ПЗ-5. Несмотря на наличие большого объёма исследований, изучающих влияние концентрации присадки на триботехнические характеристики, изме…
Abstract The regulatory effects of organic cations on the structural features and functional performances of polyanions are of paramount significance, which is accompanied by substantial challenges as well as promising opportunities. Herein, we report two monomeric zirconium-substituted phosphotungstates functionalize…
Abstract This review aims to integrate advancements in the rational design of Cu nanoclusters (NCs) from the past decade. Atomically precise Cu NCs have emerged as promising materials for highly active catalysis, due to their low cost and high efficiency as well as well-defined structures. The absolute monodispersity…
Topology optimization has been widely applied to dielectric graded insulation design in gas-insulated switchgear (GIS); however, the selection of optimization parameters remains challenging due to strong coupling among design variables and the high computational cost of conventional parametric scanning methods. To add…
A technological process and equipment for producing anti-corrosion coatings on large-diameter pipes have been developed. This process includes shot blasting and dust removal, induction heating, application of powder material, subsequent polymerization, and cooling of the finished coating. Approaches to developing equi…
Abstract Engineering physiologically relevant cardiac substrates requires precise control over both electrical and mechanical cues to guide cardiomyocyte functions and features. In this work, we report a biomolecular-based approach toward spatially controllable photostimulation of cardiac behavior via digital light pr…
ABSTRACT Organic electrochromic materials offer significant potential for dynamic optical regulation in both the visible and near‐infrared regions, particularly for applications in intelligent camouflage and thermal management. Guided by the proton‐coupled electron transfer (PCET) mechanism, this study designed a pH‐r…
Cerium oxide (CeO 2 ) represents a promising candidate for energy storage owing to its mixed-valence states (Ce 3+ /Ce 4+ ) and outstanding chemical stability. Despite these advantages, its low intrinsic electrical conductivity remains a major obstacle to achieving high electrochemical performance. Nickel incorporatio…
Abstract We have developed Density Functional Tight Binding models for cerium and cerium oxide with generalized gradient approximation and hybrid functionals that accurately predict the electronic band structure of these materials. We show that determination of a many-body repulsion energy with the Chebyshev Interacti…
ABSTRACT Extensive research has established the relationship between processing conditions, morphology, and resulting properties of microfibrillar composites (MFCs). This study investigated the effects of atmospheric pressure air plasma jet (APPJ) treatment during melt blending on the viscosity ratio and dispersion of…
FINDING: Caspar-Klug triangulation numbers (T=h²+hk+k²) define icosahedral viral capsid geometry via hexagonal lattice indexing, with base-60 resonance in crystallographic symmetry. MATH: - Triangulation number: \( T = h^2 + hk + k^2 \), where (h,k) are integer coordinates on a hexagonal lattice. - Number of capsid pr…
ABSTRACT Despite significant advancements in MXene synthesis, the etching and delamination processes remained largely empirical, with limited understanding of their underlying mechanisms. Here, we uncover the pivotal role of chloride ions (Cl – ) in enabling spontaneous delamination by facilitating Li + ion intercalat…
FINDING: Penrose tilings are aperiodic and their tiling problem is computationally undecidable, equivalent to the halting problem. MATH: - Penrose tilings use two rhombi (angles 36°/144° and 72°/108°) with edge lengths in golden ratio φ = (1+√5)/2 ≈ 1.618. - Aperiodicity enforced by matching rules that forbid periodic…
ABSTRACT For organic–inorganic composites of epoxy with polyhedral oligomeric silsesquioxanes (POSS), dispersion of POSS is ‐ pivotal to influence the thermomechanical properties of materials. However, this effect has scarcely been investigated. This work is to unlock the correlation of morphologies with thermal, mech…
Securing heavy metals within cement clinker phases is a sustainable strategy for solid waste upcycling, yet the atomic‐scale mechanisms governing the stability and surface properties of these phases remain elusive.
