Guanidino-functionalized aromatics (GFAs) comprise an important class of redox-active organic molecules and ligands with a variety of applications. In this work, we report the synthesis and chemistry of novel GFAs with a pyridine core functionalized in 2 and 3 positions with two guanidino groups. The two guanidino gro…
The construction of protocell networks with self-regulated spatial dynamics and functions is an important challenge in the emerging field of colloidal systems chemistry. Existing strategies predominantly produce protocell networks with fixed or randomly distributed spatial organization, relying on direct surface inter…
This technical note publishes a reproducible arbitrary-precision layer for the OUXSPACE / STRING THEORY-2 fine-structure programme. Its primary mathematical object is the closed form αₛₜ₂ = 105/[2π(2125+2√6810)], generated by the declared OUXSPACE closure chain. The note provides: (i) the exact algebraic compression o…
The objective of this study was to identify and experimentally validate novel antioxidant peptides derived from salmon collagen through an integrated bioinformatic and experimental workflow. Collagen sequences from Salmo salar were subjected to in silico enzymatic hydrolysis, and the resulting peptides were characteri…
تحلیل بنیادین و بازنویسی تانسوریِ چرا بوزونهای W و Z اینقدر سنگین هستند؟ (مسئله جرم و برد نیروی ضعیف) در چارچوب فیزیک اطلاعات حمزه (HIP-1155) بر اساس پروتکل جامع ۱۰ مرحلهای ۱. مقدمه: پارادوکسِ جرم بوزونهای گیج و برد فوقالعاده کوتاه نیروی ضعیف در مدل استاندارد در فیزیک ذرات بنیادی، برد یک نیرو ارتباط مستقیمی با جر…
To address the energy conversion and entropy change during the thermoelastic effect, the first and second laws of thermodynamics are applied in the coupled thermal and elastic fields in this paper to analyze these two issues. The underlying physical mechanism for energy conversion is explained in details and the speci…
Fused Deposition Modeling (FDM) has been widely studied for the manufacture of light-weight polymer components. However, the process parameter selection significantly effects the production efficiency, material consumption and vibration damping performance. In the present study, the effects of slice height (0.17–0.33…
The advancement of cell-populated bioengineered constructs (BECs) has created an ever-increasing demand for effective cryopreservation strategies that guarantee long-term storage without compromising structural integrity or biological function. By allowing constructs to be stored until required, cryopreservation helps…
Quasi solid-state lithium metal batteries are promising next-generation energy storage systems owing to their high energy density and enhanced safety. However, severe interfacial incompatibility between solid electrolytes and electrodes, along with uneven lithium deposition, remains a major obstacle to their practical…
Abstract Cracks are inevitable defects in engineering applications of round bamboo. However, existing research on the effects of cracks on the mechanical properties remains insufficient. In this study, systematic mechanical tests were conducted on crack-free (B1) and cracked (B2) round bamboo specimens, including comp…
Abstract During the long-term preservation of ancient books, acidic substances will continuously erode and cause them to suffer severe damage. As a mild deacidification agent, nano-MgO is often dispersed in organic solvents for large-scale deacidification. This study is based on small-scale deacidification in the labo…

The development of thermally stable and highly dispersed catalyst systems is essential for advanced catalytic applications involving carbon dioxide conversion and related heterogeneous reactions. In the present study, a novel rare-earth-metal-promoted alumina catalyst co-doped with dysprosium (Dy) and nickel (Ni) was…
In multilayer ceramic capacitors, the internal electrodes are fabricated by printing thin layers of nickel paste, which contains a dispersant to prevent the agglomeration of nickel powder particles within the paste. We used molecular dynamics simulations and cryogenic focused ion beam-scanning electron microscopy to i…
ABSTRACT Incorporating π‐conjugated organic spacers in layered “2D” perovskites in order to extend solar light harvesting has remained a challenge, as typically‐incorporated spacers (e.g. phenethylammonium, PEA + ) do not absorb deep into the visible spectrum. Here, we introduce a visible‐light‐absorbing π‐conjugated…
Abstract A novel aluminum-coated biochar derived from açaí waste was successfully engineered via physical vapor deposition (magnetron sputtering) to remove the emerging pharmaceutical contaminants clorazepate (Clz) and diclofenac (Dic) from synthetic and real aqueous systems. Aluminum deposition at 200 W significant…
Abstract In this study, the adsorption behavior of uranium, U(VI), and neodymium, Nd(III), onto metal–organic framework (MOF)-303, exhibiting a high surface area and tunable functional groups, was systematically investigated. Batch adsorption experiments were performed to evaluate the effects of solution pH, initial m…
Abstract Vertical organic field-effect transistors (VOFETs) are promising for low-voltage, high-speed optoelectronic applications; however, achieving both reliable switching in ultrathin channels and high current density with uniform micrometer-scale operation remains challenging. These limitations arise from drain-se…
Abstract A method for forming highly porous poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) composite particles with an excess nonconductive PSS component via spraying into liquid nitrogen, followed by freeze-drying, was proposed. The additional PSS content both compensates for the excess charge of P…
Abstract Chemical pesticides remain indispensable for crop protection, but inefficient delivery and overapplication lead to resistance and environmental risks. Cyproflanilide is a novel meta-diamide insecticide active against a broad range of agricultural pests. Here, we developed a star polycation (SPc) nanocarrier t…
