The control and modification of the surface’s wettability is a surface engineering task demanded by several applications that use material as metals like copper. Laser irradiation is a well-explored technique to modify the roughness of the surfaces which is required to modify their wettability. Despite this, the obten…
Abstract Among the burning plasma controllers for research fusion reactors, the dud detector will be of primary importance as it determines whether the plasma is performing well or if it is a dud. In the latter case, the discharge needs to be terminated to remain within tritium and neutron activation limits. To this s…
We study a shape optimization problem for a stationary linear micropolar fluid. The objective is the squared L 2 -gap between the microrotation and the local vorticity. This cost measures the deviation of the micropolar model from the limiting Stokes-type regime in which microrotation is aligned with vorticity. The an…
Abstract Cu-doped rutile TiO₂ microstructured films were synthesized through a controlled hydrothermal route to elucidate the influence of Cu incorporation on dopant-induced lattice distortion and facet restructuring, which influence the electronic properties of rutile TiO₂. Increasing Cu incorporation promoted a prog…
The concept of a spatially varying spin field, or Electron Spin Spatial Texture (ESST), is introduced as a novel framework for describing the internal magnetic ordering of electronic systems beyond the conventional scalar magnetization. In ESST the spin vector S(x,y,z) is allowed to vary continuously in space, giving…
The clinical efficacy of platinum-based chemotherapeutics is frequently diminished by the emergence of resistance during prolonged treatment. Cisplatin (DDP)-resistant tumors adapt to chemotherapeutic stress by establishing a new state of adaptive homeostasis that sustains cellular survival under drug pressure, albeit…
The concept of elasticity is central to the understanding of how materials deform and recover under external forces. Classical continuum mechanics describes elasticity through smooth fields of stress and strain that are valid when the material dimensions are much larger than the characteristic interatomic spacing. How…
Abstract: 2-aminothiazole was diazotized with sodium nitrite and 6 (M) hydrochloric acid then diazonium salt was coupled with 2,6 - diamino pyridine at 00c. Then the solution was basified with 0.001(M) sodium hydroxide solution until PH=6.0 was reached. A red Precipitate began to settle immediately. Ruthenium (II) com…
Abstract Developing polyethylene-like (PE-like) materials with built-in chemical recyclability provides a promising strategy for addressing the end-of-life challenges of persistent polyolefins. Entropy-driven ring-opening polymerization (ROP) of macrolactones offers an attractive route to floor-temperature (Tf)-regula…
ABSTRACT Wound healing is a complex biological process that requires advanced therapeutic strategies, within which bioactive‐loaded polymeric matrices represent a central approach. However, the therapeutic efficiency of wound‐healing biomaterials depends on how effectively bioactive molecules are retained and released…
Titanium-based implants remain among the most successful biomaterials in modern dentistry, but accumulating evidence demonstrates that titanium is not biologically inert under long-term physiological conditions. Mechanical loading, tribocorrosion, acidic and oxidative microenvironments, and biofilm-driven electrochemi…
By arranging 240 piezoelectric elements in the exact geometry of the E8 root system and driving them at the base 132 Hz frequency with successive phi‑phase shifts, a self‑similar 8‑fold phononic bandgap emerges. Each of the eight phase‑locked sub‑lattices reproduces the E8 root pattern at a smaller scale, creating a f…
Abstract In this work V 2 O 5 –NiO nanocomposites were synthesized by a hydrothermal method with varying V 2 O 5 concentrations (0.1, 0.3, 0.5 and 0.7 N) and fabricated into thick films using screen printing. Structural analysis by XRD confirmed the cubic phase of NiO and orthorhombic V 2 O 5 , with crystallite size d…
Abstract Type A carbohydrate-binding modules (CBMs) preferentially recognize crystalline polysaccharides such as cellulose and chitin, yet some can also bind synthetic plastics, suggesting that their recognition properties can be redesigned through protein engineering. Here, we used directed evolution to alter the sub…
The adsorption behaviour of anionic and cationic dyes, namely methyl orange (MO) and methylene blue (MB), respectively, has been studied on carbon-silica composites. These composites were produced through the valorisation of waste vinasse from industrial sugar production as the carbon feedstock, while the silica produ…
Abstract Deeply buried carbonate reservoirs represent a critical frontier and high-priority target for global hydrocarbon exploration. However, the genetic mechanisms and spatial distribution of high-quality deeply buried carbonate reservoirs remain highly contentious. This study focuses on the Middle Permian Maokou F…

ABSTRACT Dendrite growth and interfacial side reactions severely limit the cycle life of sodium batteries. While electrolyte additives represent the simplest mitigation strategy, conventional additives rely on single chemical driving mechanisms, and pose environmental concerns. Here, we propose a bio‐adaptive approach…
Asphalt binders play a central role in road infrastructure, and their performance is heavily influenced by their chemical composition and response to temperature changes. In this study, we used all-atom molecular dynamics simulations to explore how variations in the chemical structure, particularly the presence of het…
ABSTRACT Highly stretchable gel fibers are increasingly critical given the growing miniaturization and adaptivity demands within flexible wearable devices. Current fiber‐based iontronics, however, exclusively rely on hydrogels with limited environmental tolerance. Moreover, most existing gel systems exhibit insufficie…
