We investigate the nonequilibrium response of a strongly coupled hybrid lead-halide perovskite model subjected to an idealized localized kinetic thermal pulse. In the revised manuscript, the word “driving” refers specifically to velocity-rescaling within a finite spherical region, not to explicit optical excitation, c…
This study numerically presents the design of a multi-band metasurface-based microwave absorber designed to operate in the S, C, X, and Ku bands. The proposed structure exhibits simulated peak absorption values above 95% at resonance frequencies of 2.9 GHz, 6.3 GHz, 11.7 GHz, and 17.5 GHz, with narrowband fractional b…
Abstract Respiration is a continuous biomechanical energy source for wearable devices, but its low airflow velocity and pressure limit its direct use in powering practical electronics. Triboelectric nanogenerators (TENGs) are attractive for respiration-based energy harvesting because of their compactness and effective…
ABSTRACT Solar‐driven water evaporation is a highly promising low‐carbon technology owing to its clean operation and off‐grid applicability. However, diurnal variations in solar position cause significant fluctuations in freshwater production, hindering its practical deployment. Inspired by the omnidirectional light‐h…
Abstract Particles settling through sharply density-stratified fluids exhibit transient dynamics that remain difficult to capture with classical buoyancy--drag models, including strong deceleration, prolonged retention near the interface, and, in some cases, apparent bouncing. Existing mechanistic models that reproduc…
Cyclocarbons are among the most elusive carbon allotropes, and their integration into functional photochemical systems remains a major challenge. Here, we present a computational design of a photoactive cyclo[48]carbon [4]catenane in which supramolecular encapsulation by PDI-based macrocycles is predicted to stabilize…
The development of low-carbon binders from industrial solid wastes can reduce Portland cement use and support sustainable construction. However, the combined roles of alkalinity supply, sulfate reaction, and reactive silica supplementation in ground granulated blast furnace slag (GGBS)–calcium carbide slag (CCS)–desul…
Wind energy, an abundant renewable resource, remains difficult to harness efficiently due to fluctuating speeds and unpredictable directions. In this work, we present a wind bell-inspired triboelectric nanogenerator (WB-TENG) designed for omnidirectional, variable-speed wind harvesting, utilizing layered triboelectric…
In this paper, we present a theoretical study of atomistic mechanisms of polaron formation in BiVO4 and its impact on solar-to-hydrogen (STH) conversion efficiency. We simulated polaron formation, calculated the energies of polaron states, and computed the frequency-dependent dielectric function using first-principles…
ABSTRACT Accurate intraoperative identification and complete resection of tumor lesions are essential for effective cancer treatment, especially for microtumors. However, conventional fluorescence imaging is hampered by tissue autofluorescence interference, limited penetration depth, and low signal‐to‐background ratio…
Covalent organic frameworks (COFs) have garnered increasing attention as versatile platforms for Li+ conduction in lithium-based batteries; however, achieving high ionic conductivity in COF-based electrolytes remains a formidable challenge. Herein, we demonstrate a robust cationic vinylene-linked COF (COF-Br) as an ef…
Microplastics (MPs) and nanoplastics (NPs) accumulate in human hepatic and gastrointestinal (GI) tissues. However, differences in sampling strategies, tissue preparation, analytical techniques, and quality assurance procedures have resulted in substantial methodological heterogeneity, limiting the comparability and re…
تم تفاعل الكيتوسان مع بارا-ميثيل بنزالديهايد لإنتاج قاعدة شيف للكيتوسان. استُخدمت تقنية خلط المحاليل لتحضير مزيج بوليمري مع بولي فينيل الكحول. تم تشخيص جميع المركبات المحضّرة بواسطة مطيافية الاشعة تحت الحمراء والتحاليل الحرارية والمجهر الالكتروني الماسح إضافةً إلى تقييم الفعالية الحيوية. أظهرت نتائج مطيافية الاشعة تحت…
Abstract We report a catalyst-free, open-air synthetic method for 3-cyano-4,5-dihydropyrroles via photoinduced electron donor–acceptor (EDA) complexes using arylglycines and enones in ethyl acetate under mild conditions. This green method avoids metals and toxic additives, accommodates 35 examples including chromone-f…
Corrosion-resistant coatings with a double-layer structure are deposited on the surface of S30408 stainless steel at welding currents of 170 A, 200 A, and 230 A using metal active gas (MAG) arc welding technology. The influence of welding current on the microstructure, microhardness, wear resistance, and electrochemic…
Silicone elastomers are attractive matrices for transdermal drug delivery systems, but the controlled release of poorly water-soluble drugs from hydrophobic silicone networks remains challenging. Medical-grade silicone elastomers are generally regarded as chemically stable, biologically inert, and highly biocompatible…
Macroplastic pollution in rivers is an increasing environmental concern because rivers function simultaneously as active transport pathways and temporary storage compartments for land-based plastic waste. This study investigated the spatial distribution, composition, and size characteristics of riverbank and floating…
Abstract This study establishes a bottom-up strategy for fabricating electrochemically addressable nanocavities with high structural precision and reproducibility by templating silica sol–gel thin films with polystyrene nanoparticles (PS NPs) on conductive electrodes. Controlled PS NP adsorption, sol–gel encapsulation…
ABSTRACT Developing multifunctional materials that integrate exceptional infrared (IR) stealth with long‐term environmental stability remains a formidable challenge. Inspired by the synergistic function of human skin hair and sweat glands, we report a hydrophobic, highly conductive, and anti‐oxidant IR stealth materia…
ABSTRACT As the aviation industry is characterized by a growth in aircraft size and flight frequency, runways are subjected to higher operational demands. Therefore, under the effect of repeated aeroplane loads which impair macro- and micro-texture as well as skid resistance, the surface friction of runways gradually…
