Universal Condensation Principle
Graphene is a two-dimensional (2D) nanomaterial that has garnered significant attention since its discovery in 2004 due to its unique physiochemical, electrical, mechanical, optical and thermal properties. Liquid phase exfoliation (LPE) is a versatile method of graphene production that is scalable…
Geopolymers are promising inorganic binders and alternative cementitious materials due to their high mechanical performance, durability, and reduced environmental impact in comparison with Portland cement. Nevertheless, the application of geopolymeric materials is limited due to the use of conventi…
ABSTRACT Suppression of excited‐state non‐radiative recombination is pivotal for overcoming efficiency bottleneck in organic optoelectronics. However, in film, mechanism of aggregates’ excited‐state non‐radiative recombination and how to suppress its rate ( k nr ) remain unclear. Here, taking class…
The Christiansen effect, owing to its unique wavelength-selective scattering characteristics, exhibits significant application potential in fields such as optical modulation, biomimetic structural coloration, sensing and smart windows, and is gradually transitioning from theoretical research to fun…
Abstract Electric vehicle (EV) battery fires pose acute occupant safety risks, yet no systematic Design for Six Sigma (DFSS) framework exists to optimize interior fire-safety barrier materials under simultaneous thermal, mass, and toxicological constraints. This study applies a full DMADV methodolo…
This work presents a novel compact frequency-selective surface (FSS) exhibiting ultra-wideband (UWB) band-stop features, excellent angular stability, and polarization insensitivity for advanced electromagnetic shielding and antenna enhancement applications. The suggested FSS consists of cross-dipol…
Microplastic control often removes particles from water without destroying polymer carbon and transfers this carbon to sludge or other residual streams. Catalytic treatment can deconstruct the polymer, yet surface oxidation, particle loss, chain scission, and mineralization are frequently reported…
The grafting of poly(ester carbonate) statistical and block copolymers onto cellulose nanocrystals (CNC) is reported through organocatalyzed ring-opening copolymerization initiated by the CNC surface hydroxyl groups. The grafting percentage by weight is in the range of 31 to 83% synthetic polymer.…
The formation of two-dimensional protein crystallites on solid surfaces is crucial in both natural biological processes and bottom-up nanofabrication. However, direct molecular-level insight into the dynamic evolution of epitaxial interfaces has remained challenging. Here, using in situ atomic forc…
Polymers enable countless modern technologies, yet vast regions of their chemical space remain unexplored. Traditional polymer discovery relies on chemical intuition, ingenuity, and experience (with a healthy dose of serendipity), yet it fails to leverage millions of potentially accessible and synt…
In this study, a tubular CuO/Cu 2 O-Cu 7 S 4 (COS-3) ternary heterojunction photocatalyst was successfully prepared by electroless plating, high-temperature oxidation and hydrothermal vulcanization for the efficient degradation of tetracycline antibiotics in water environment, combined with the adv…
Textiles with fluorescent and further advantageous chromatic effects are available for various different applications, such as home textiles, sport textiles, children clothes or safety equipment. The main aspect for this type of textile products is their functionality. Nevertheless, due to the curr…
Early cancer detection can expand treatment options and improve patient survival, but it requires tests that can be repeated with minimal patient burden. Urine and saliva can be collected non-invasively and may contain cancer-associated nucleic acids, proteins, and extracellular vesicles. Clinical…
Abstract The development of ionotronic hydrogels that can transmit electrical signals and withstand mechanical deformation holds great promise for applications in soft electronics and human–machine interfaces. However, their operational durability is often compromised by mechanical damage, such as…
Abstract Developing ZnO-based photocatalysts for organic-pollutant removal requires materials in which structural modification, surface accessibility, and reactive oxygen species generation are effectively balanced. In this work, Ho/Ga codoped ZnO powders were evaluated as photocatalysts for the re…
Abstract First-principles calculations show that angstrom-scale slit confinement alone activates O2 via the coupled spin, charge, and bonding reconfiguration. Across electronically distinct walls (graphene, h-BN, and g-C3N4), reducing the gap drives a stepwise evolution from triplet O2 to superoxid…
Paper 122K investigates whether dimensionless Holosphere mechanics contains a finite nonzero structural threshold for closed recurrent motion. The model uses a face-centered-cubic support network of independently spinning Holospheres, with vacancies representing unoccupied support sites. The final…

Sprites are transient luminous events produced in the mesosphere by quasi-electrostatic fields generated above intense thunderstorms. In this work, sprite streamer discharges are simulated using the Afivo-Streamer framework under mesospheric conditions, employing a fluid plasma model based on the d…
