Flash Joule Heating (FJH) represents a disruptive strategy for accessing nonequilibrium materials, yet atomic-scale interfacial evolution under subsecond thermal shocks remains poorly understood. Herein, millisecond FJH is employed to freeze critical metastable interfaces, unraveling the kinetic origin of stable sodiu…
Mechanical metamaterials enable control of macroscopic properties, such as stiffness, through the careful design of their internal architecture. The primary objective of this research is to develop a unit cell consisting of a polymeric metamaterial with embedded pins that provides tunable mechanical behavior through a…

Solid dispersions are one of the most promising strategies to overcome the poor aqueous solubility of some drug substances. However, the physical and chemical instability of solid dispersions has limited their use. The purpose of this study was to assess the risk of factors affecting the dissolution and chemical stabi…
The rapid expansion of the wind energy industry is generating an increasing volume of waste wind-turbine blades (WWTB), creating an urgent need for efficient and sustainable recycling technologies. Composed primarily of cross-linked epoxy resins reinforced with glass or carbon fibers, WWTB are inherently difficult to…
Light noble gases such as helium (He) and argon (Ar) are conventionally defined as chemically inert under ambient conditions due to their stable closed-shell electronic configurations. Although recent high-pressure physics has revealed interstitial trapping phenomena under megabar regimes, these physical packages spon…
ABSTRACT Excellent photothermal conversion efficiency and mechanical durability determine the application prospects of photothermal icephobic coatings. With the four core effect and flexible bandgap structure, entropy‐driven materials exhibit unique structural merits and are worth in‐depth exploration in icephobic fie…

Holotype • Clitellate specimen (34 mm in total length, dissected), Chang’an Road, Shuanghe County, Xinjiang Uygur Autonomous Region, China, 44.8389°N, 82.3422°E, 1,943 m elev., 21 May 2025, coll. Yufeng Zhang (CNWN 02_02). Paratypes • Three clitellates (CNWN 0…
Metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) are highly tunable in pore structure and chemical environment, yet their discovery remains slow and fragmented. Synthesis reports are often difficult to compare, characterization data are laborious to interpret, and computational predictions rarely…
This computational study proposes a novel titanium production process using a quaternary MgCl₂-CaCl₂-NaCl-KCl molten salt for in-situ electrolytic co-deposition of Mg and Ca for complementary reduction of TiO₂. Thermodynamic calculations (ΔG° = -231.0 to -307.5 kJ/mol at 600°C) show Ca deoxidation reaches 20.2 ppm ver…
Lithography-based ceramic manufacturing (LCM) is a capable additive manufacturing (AM) or three-dimensional (3D) printing technology for producing ceramics with high precision and excellent mechanical properties similar to conventionally manufactured components. This AM method is a digital light processing-based vat-p…
Abstract Microbial respiration-triggered reductive transformation of dissolved organic matter (DOM) plays a central role in O2 activation and, consequently, As(III) oxidation under fluctuating hydrological conditions. However, the key DOM components and their molecular transformations associated with this electron-tra…
As an emerging sensing paradigm for magnetic nanoparticles (MNPs), opto-magnetic detection offers distinct advantages over conventional magnetic methods, including remote operation and non-invasiveness. Optical readout enables stable monitoring of the dynamic response of MNPs under magnetic excitation and has recently…
In this study, we synthesized a lignin-based superabsorbent hydrogel (LWR) to relieve severe evaporation and structural degradation in inland saline–alkali soils. The LWR was prepared via free-radical graft copolymerization of calcium lignosulfonate (CL) and acrylic acid (AA), with its swelling performance optimized s…
The 144,000-node geodesic grid — an icosahedron subdivided at frequency f = 120 with its two poles removed — is shown to carry two independent arithmetic structures drawn from two different quadratic fields. In ℚ(√5): the icosahedron's vertices lie in ℤ[φ], and every pre-projection subdivision node of a frequency-f gr…
This article proposes a new design for a double excitation synchronous machine. The end-shields with an L-shaped core are introduced to lower the magnetic resistance. The analyses are accomplished by using a three-dimensional finite element method, required by the truly three-dimensional flux paths of the machine. The…
Per- and polyfluoroalkyl substances (PFAS) represent a critical class of persistent environmental pollutants that challenge conventional remediation technologies. Metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and the emerging metal–covalent organic frameworks (MCOFs) have attracted growing inter…
Abstract A method to produce ductile iron with a novel austenite plus martensite microstructure has been discovered by combining an appropriate chemistry of manganese, nickel, and carbon, with an appropriate heat treatment. Various austenitizing temperatures and times were used to change the amount of carbon in soluti…
Source term modeling for TRistructural ISOtropic (TRISO) fuel has been performed for previous reactor designs, but few are available in the open literature. Thus, there is a need to develop a simple, versatile, and mechanistic model of fission product release and transport in gas reactor cores that can be applied to a…
