The shielding effect in turboexpander-equipped natural gas pressure reduction stations: an advanced exergoeconomic analysis

Natural gas pressure reduction stations dissipate exergy when gas pressure is throttled from transmission to distribution levels. Turboexpanders recover part of this energy, but their expansion requires preheating to prevent hydrate formation, and the preheater-turboexpander coup...

Sodium butyrate-mediated HDAC inhibition under hypoxic conditions modulates redox balance and tumor cell behavior in MCF-7 human breast cancer cells

Abstract Hypoxia and epigenetic dysregulation are key contributors to breast cancer progression and therapeutic resistance. However, the interaction between histone deacetylase (HDAC) inhibition and hypoxia-associated signaling remains incompletely understood. This study therefor...

Acute effects of l-Citrulline vs. Citrulline malate supplementation on resistance training performance, muscle soreness, and blood biomarkers in resistance-trained men: a double-blind placebo-controlled counter-balanced trial

The current study compared the ergogenic effects of L-Citrulline (LC) and Citrulline Malate (CM) supplementation to examine the synergistic potential of LC and malate, as well as examining the effects of higher doses of LC (8 g) and CM (12 g) than commonly utilized. Twenty-two re...

Anion-Activated Supramolecular Proton Relays Enable Neutral-pH and Seawater Oxidation

Abstract Neutral-pH and direct seawater oxidation are critically hindered by sluggish proton-coupled electron transfer (PCET) and competitive chloride corrosion. Here, we employ surface-confined azacrown macrocycles of varying nitrogen content as supramolecular proton-management...

Anthocyanins/MgO–carbon dots obtained from Rosa canina fruit to enhance the performance of locust bean gum-sodium caseinate aerogels for intelligent packaging application

Abstract The aims of the current study were to develop locust bean gum-sodium caseinate (LBG-SC) aerogels containing anthocyanins/MgO–carbon dots extracted from Rosa canina fruit for monitoring beef meat freshness. The LBG-SC aerogels containing R. canina fruit extract (RCE, 5%)...

Agronomic drivers of Tribenuron-methyl resistance in wild mustard (Sinapis arvensis) in dryland wheat fields of western Iran

Understanding the impact of common agronomic practices on the evolution of herbicide resistance is essential for developing sustainable weed management strategies that incorporate non-chemical control methods. In this study, we investigated the frequency of Tribenuron-methyl (TBM...

Green synthesis of functionalized CuO, ZnO and Fe₂O₃ nanoparticles using medicinal plant extracts for early seedling growth evaluation

Abstract Phytochemical compounds are among the most widely used natural materials and have attracted much attention in recent years in various fields and industries. In biological applications, they can be used as preservatives and antifungals. This study investigated the effect...

A novel geofoam-geogrid composite for protecting buried pipelines against blast loads

This study investigates the performance of a novel geofoam-geogrid composite in mitigating the impact of surface and subsurface blasts on API-× 65 steel pipelines buried 2 m below ground level. A 3D nonlinear finite element method was employed to analyze the effects of blast char...

Nanoarchitectonics of phenolic acid-functionalized gold nanoparticles: A bioinspired nanoplatform for erythrocyte membrane and protein protection, bacterial and cancerous cellular toxicity

Abstract Ferulic acid-trans form (TFA) was applied for the biosynthesis of gold nanoarchitectonics (TFA-GNPs) as a reducing and stabilizing agent under optimal conditions. The most favorable conditions for this synthesis included a pH of 7, a reaction duration of 4 h, and a tempe...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Abstract Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O...

Quercetin biomolecule-stabilized gold nanoparticles: a synthesis-to-biotherapy platform for antibacterial, anti-hemolytic, anti-inflammatory, and anticancer applications

This study aimed to synthesize gold nanoparticles (GNPs) using quercetin (QU) biomolecule as a natural reducing and stabilizing agent and to evaluate its biointerface and biotherapeutic potential. The bio/nano-formulated QU-GNPs with crystalline structure from XRD pattern showed...

Optimizing the removal of color and impurities from sugar beet syrup using bentonite/iron oxide nanocomposite

Abstract Efficient removal of colorants and impurities is a crucial step in the sugar industry to ensure high-quality final products and to minimize operational costs. This study investigates the performance of a magnetic bentonite/iron oxide nanocomposite for removing color-form...
