Abstract To achieve precise oil film thickness measurement in enclosed cavities of complex industrial components, this study proposes a double-layer oil film measurement method based on time-of-flight positron annihilation detection. The arrival-time difference of coincident γ photons is used to estimate the annihilat…
Selenium (Se) is an essential micronutrient for human health; however, the efficient conversion of inorganic Se into organic forms remains challenging. Microalgae have emerged as promising platforms for sustainable production of functional food ingredients due to their rapid growth, metabolic versatility, and capacity…
ABSTRACT Asphaltenes exhibit potential for various applications, such as polymer fillers. Moreover, poly(butadiene‐1,4) (PB) is among the unsaturated synthetic rubbers and one of the most industrially important raw materials. Moreover, polymers show deviations from their bulk behavior at solid interfaces when confined…
This study presents an investigation into the Poisson’s ratio behavior of 3D-printed auxetic lattice structures with varied unit cell sizes, strut lengths, and inclination angles. Auxetic lattice structures with various unit cell sizes (3 × 3, 4 × 4, and 5 × 5 mm3), strut lengths (1.25 and 1.9 mm), and inclination ang…
Electronic correlations govern the dynamical behavior of electrons in atoms, molecules, and solids. Traditional approaches focus on the strength of correlations, yet they overlook the possible dependence of correlation propagation on the velocity of interacting electrons. This paper introduces the Electron Correlation…
We present a continuous parameter phenomenological model for chemical bonds. Based on a unified parameterization of bond length and bond energy, we introduce the concept of bond structure looseness, explaining the continuous transition between different bond types. The model predicts bond lengths for 54 covalent bonds…
Este póster científico presenta un estudio de ingeniería de calidad enfocado en el empaque primario (blister) utilizado para los catéteres Sure Pro. El trabajo surge porque el molde original (Revisión A), tras uso prolongado, comenzó a mostrar variabilidad dimensional, y al no existir especificaciones internas en el p…
Abstract In this paper, an octagonal slot antenna based on Substrate Integrated Waveguide (SIW) technology is introduced for generating various Orbital Angular Momentum (OAM) modes. Utilizing a horseshoe-shaped feed, the antenna can generate electromagnetic waves with OAM modes l = 0, ±2, and ±3 at frequencies of 6.94…
ABSTRACT Enhance charge transmission performance of sliding mode triboelectric nanogenerators (TENG) is critical approach for achieving efficient energy harvesting in constructing self‐powered systems. However, the charge transmission efficiency in practical applications remains challenge, and the output current regul…
ABSTRACT The integration of two‐photon excited fluorescence and x‐ray scintillation into a single material entity is highly desirable for advanced multiscale medical and photonic applications. However, due to the lack of multiscale energy absorption capabilities or the uncontrollability of emission pathways, conventio…
ABSTRACT Metal halide perovskites have attracted considerable research interest due to their outstanding optoelectronic properties. In this work, a cost‐effective and sustainable solvothermal‐assisted approach was developed for the synthesis of non‐toxic, stable, and highly efficient lead‐free copper(I)‐based iodine p…
This review examines the cascade use of wood waste with a specific focus on medium-density fiberboard (MDF) as a wood-based biocomposite within the circular economy. MDF is widely used in furniture, interior and construction-related applications, generating increasing amounts of production residues and post-consumer w…
Abstract Magnesium–sodium hybrid-ion batteries combine a safe Mg-metal anode with rapid Na+ cathode kinetics, but suitable cathodes remain scarce. Here, Cu2+ preintercalation regulates hydrated V2O5 through three-dimensional nanosheet-assembled architecture evolution, accompanied by modulation of the interlayer water…
Nb-Si based in-situ composites are candidate materials for 1300 °C-class gas turbine blades, yet the trade-off among room-temperature toughness, high-temperature creep resistance, and oxidation resistance has remained unresolved for decades. Based on reanalysis of publicly available literature data, this paper propose…
The summary overview of the range of resins with their characteristics available from Chinese manufacturers, potentially suitable for the manufacture of UV, LED and EB paint and varnish materials for painting rolled and sheet metals, metal products, is presented.
Abstract Protein science has long grappled with two foundational paradoxes. The first demonstrates that proteins cannot fold via random conformational searches, given the astronomical number of possible configurations. The second establishes that the amino acid sequence thermodynamically determines the native structur…
This paper examines the petroleum resistance of epoxy resin-based paint and varnish compositions for the production of coatings designed to protect the interior surfaces of pipelines operating in modern oil transportation environments. Optimal components for the production of a high-solid primer-enamel coating were se…
ABSTRACT Chiral perovskites enable spin‐polarized light emission through the chiral‐induced spin selectivity (CISS) effect, offering a pathway toward magnet‐free spin‐optoelectronic devices. However, in most CISS‐based luminescent systems, the spin‐filtering and light‐emitting functions are intrinsically coupled, whic…
This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics. As a prominent example, the efficient epigenetic control operative in nucleosome-DNA interactions was selected. Conceptually, transcription activation by specific acetylat…
Global cement production totals approximately 4 billion tonnes per year and accounts for 7 to 8% of annual CO₂ emissions. Industrial byproducts can partially replace cement but supplies of established materials like fly ash and slag are declining. Methane pyrolysis produces hydrogen and a solid carbon nanotube (CNT) b…
