Foam flooding is a promising enhanced oil recovery (EOR) while improving the gas sweep efficiency problem of gas flooding. On the other hand, nanotechnology has paved the way for utilizing nanoparticles in surfactant foam while improving foam stability, lamella thickness, bubble size distribution, and oil recovery. The significant difference between nanoparticles and surfactants as foam stabilizers is the adsorption energy of nanoparticles at gas-liquid interfaces, which is thousands of times bigger than surfactants. However, previous studies on nanoparticles' foam adsorption energy are limited by using only nanoparticles (in the absence of surfactants), though it is hard to generate foam since it does not reduce surface tension significantly. Thus, the objective of this study is to determine the adsorption energy of hydrophilic silicon dioxide (SiO2) and partially hydrophobic silicon dioxide (PH SiO2) nanoparticles in the presence of anionic sodium dodecyl sulfate (SDS) and cationic cetyltrimethylammonium bromide (CTAB) surfactants. Another objective is to analyze and evaluate the effects of adsorption energy on foam stability. Consequently, the particle radius, surface tension, and particle surface wettability were all obtained from the maker, Du Noüy ring tensiometer, and particle surface contact angle. The result shows that the adsorption energy of PH SiO2 was a thousand times greater than hydrophilic SiO2 in the presence or absence of surfactants. Due to PH SiO2 having a slightly bigger particle radius, higher adsorption energy in the PH SiO2 system is mainly by particle hydrophobicity and surface tension. In all systems, the highest adsorption energy is achieved at the lowest concentration of nanoparticles because the increment in nanoparticle concentration reduces the surface tension, eventually lowering the adsorption energy. However, this trend is contradicted with half-life foam stability when it increases with the nanoparticles concentration until the optimum concentration is obtained, then reduced. To sum up, the evaluation of the nanoparticles' foam adsorption energy in this study supports the fundamentals of nanoparticles stabilizing foam that are also influenced by other parameters: the maximum capillary pressure, particle arrangements during film drainage, and growing aggregate and the ‘cork’ formation inside lamella.

Tolterodine tartrate (TLD) has recently demonstrated remarkable synergism when combined with either of two α1-adrenergic antagonists, doxazosin mesilate (DXZ) or terazosin hydrochloride dihydrate (TRZ), for treating urinary tract issues. Herein, a sustainability-oriented approach is adopted for integrating constant wavelength synchronous fluorescence with micellar augmentation for ultra-trace tracking of TLD in combination with DXZ (mixture I) or TRZ (mixture II). The designed protocol relies chiefly on exploiting sodium dodecyl sulfate as a biodegradable fluorescence enhancer and water as an eco-friendly diluting solvent, maintaining a fixed wavelength difference (Δλ = 20 nm) to record the drugs’ signals. Under optimal experimental conditions, favorable linearity at the nano level was achieved over concentration ranges of 20.0–200.0, 5.0–50.0, and 5.0–50.0 ng mL⁻1, with remarkable LOD (1.25, 0.90, and 0.73 ng mL⁻1) and LOQ (3.78, 2.73, and 2.20 ng mL⁻1) levels for TLD, DXZ, and TRZ, respectively. The methodology effectively evaluated the cited drugs per se, in their laboratory-prepared mixtures, and in dosage form, without impediments from one another or the tablet excipients. The outstanding ultra-sensitivity of the developed strategy permitted concurrent minute analysis of the targeted drugs in human plasma, with acceptable standard deviation (SD) values ≤ 2.40. Additionally, exceptional analytical performance has been demonstrated for the nominated medications in two environmental samples with SD values ranging from 0.59 to 1.57. The proposed work prioritizes sustainability principles by excluding harsh chemicals and convoluted procedures, constituting a cornerstone of the design. These principles were checked using: MoGAPI, AGREE, CACI, RGBfast, RAPI, and BAGI. Interestingly, the cutting-edge GLANCE tool was employed to display a quick snapshot of the framework aspects in a well-organized template, without digging into overwhelming datasets. The outcomes demonstrated the excellence of the designed methodology over reported approaches, offering proficient sensitivity, sustainability, facility, and practicability across diverse crucial matrices. These findings provide compelling evidence that the proposed work serves as an efficient, eco-friendly quantification tool for use in quality control, biological, and environmental sectors, fostering a more eco-conscious and sustainable scientific community.Supplementary InformationThe online version contains supplementary material available at 10.1038/s41598-025-27144-0.

ABSTRACT Antarctic krill, known for its abundant reserves and high nutritional content, represents a valuable resource for humanity. The purpose of this study was to explore the feasibility of simultaneous extraction of Antarctic krill oil (AKO), Antarctic krill protein (AKP), and Antarctic krill polysaccharides (AKS) from krill by three‐phase partitioning (TPP) method and the optimal extraction conditions of AKO. The fatty acid composition of AKO and the structural characteristics of AKP and AKS were analyzed and compared with the experimental results obtained by other methods. Response surface optimization results showed that under the conditions of 50% (w/v) (NH 4 ) 2 SO 4 , 1:1 (v/v) ratio of slurry to t ‐butanol, pH 5.10, extraction temperature 50°C, and extraction time 2 h, the optimal extraction yield of AKO (EY AKO ) was 17.65%. Under these conditions, the extraction yields of AKP (EY AKP ) and AKS (EY AKS ) were 9.44% and 0.25%, respectively. Additionally, AKO extracted by TPP method was rich in more polyunsaturated fatty acids (PUFAs) than traditional methods, especially n ‐3 PUFAs. The structure of AKP was analyzed by Fourier transform infrared (FTIR) and sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS–PAGE), showing that it is not damaged. The FTIR results show that AKS has the characteristic structure of homologous marine sulfated polysaccharides, indicating it is maybe a sulfated polysaccharide. This study shows that it is feasible and efficient to extract AKO, AKP, and AKS simultaneously by TPP methods. Our research provides a new way to extract nutrients from Antarctic krill. Practical Applications : This study facilitates the comprehensive utilization of the substantial Antarctic krill resource, significantly enhancing their economic value and utilization efficiency. The optimized TPP method yields AKO with both high extraction efficiency and a rich content of n ‐3 PUFAs. These two advantages combine to enable its use in high‐end AKO production while simultaneously laying the technical groundwork for valorizing AKP and AKS as main products, thereby providing more options for the Antarctic krill industry. It also serves as a valuable reference for researchers engaged in the comprehensive utilization of other marine biological resources. The preliminary structural analyses (FTIR, SDS–PAGE) of AKP and AKS provide essential preliminary data to support deeper investigation into these molecules and lay a scientific foundation for the subsequent development and application of AKP and AKS.

ABSTRACT The preparation of carbon fiber reinforced polyetherketoneketone (CF/PEKK) prepreg tapes using water‐based solvents instead of the traditional flammable and explosive alcohol solvent system is a green, safe, and challenging task. In this study, the water‐based PEKK suspension stabilized by the synergy of sodium dodecyl sulfate (SDS) and polyvinylpyrrolidone (PVP) was used to prepare CF/PEKK prepreg tapes. The effect of SDS and PVP surfactants on the stability of the water‐based PEKK suspension and the mechanical properties of CF/PEKK prepreg tapes was investigated. The results showed that SDS and PVP significantly enhanced PEKK wetting performance, achieving the optimal suspension stability at 1 wt% SDS and 0.5 wt% PVP with a stirring rate of 600 rpm. The tensile strength of CF/PEKK prepreg tape prepared using the optimal suspension solution reached 1601 MPa, which was 24.8% and 13.7% higher than that of the systems using SDS and PVP alone, and 4.6% higher than that of the traditional ethanol‐based system. This water‐based PEKK suspension presents a promising approach for manufacturing high‐performance CF/PEKK prepreg tapes and promotes the industrial application of thermoplastic composites.

The aim of this study was to systematically compare standard detergents for the generation of Decellularization Vascular Grafts (DVG) in terms of their influence on vascular key characteristics. The most common enzymatic and chemical detergents for decellularization were identified from literature, standardized and included: i) Trypsin, ii) Sodium Dodecyl Sulfate (SDS)- and iii) Triton X-100. All protocols were applied to porcine vessels and the manufactured DVG were analyzed for histological, ultrastructural morphology and biomechanical characteristics. Further, DVG were seeded with Human Umbilical Vein Endothelial Cells (HUVEC) and cultured in a bioreactor to investigate biocompatibility after decellularization. Anti-Coagulation properties were assessed by the Chandler Loop model and a platelet-activation-assay. The Trypsin and SDS treatment were the most effective protocols in terms of tissue clearance but both impaired the ultrastructural integrity of the vessel wall in contrast to the Triton X-100 treatment. Moreover, biomechanical characteristics in the test stand did not differ significantly across the applied protocols but treatment of DVG with Trypsin was associated with a reduced Young's modulus and injuries in the vessel wall in a pulsatil flow model after 30 d. Moreover, coagulation was decreased in the Trypsin-treated group and was slightly increased in the SDS group but no significant difference towards the control group was noted. DVG after Triton X-100 treatment were the only ones capable for successful cell seeding. The here presented experimental data emphasized the main advantages and disadvantages of the most common enzymatic and chemical detergents for the manufacturing of DVG.

This study investigated the impact of 1,500 ppm fluoride-containing toothpaste on the surface properties of CAD-CAM resin composites. An accelerated degradation test was performed using five commercial NaF-containing toothpastes, which were applied to two commercial CAD-CAM resin composites and stored under static conditions at 37°C for 14 days without mechanical brushing. The results showed that four toothpastes significantly increased surface roughness and reduced gloss. To further elucidate this phenomenon, a similar accelerated degradation test was conducted using experimental aqueous solutions containing NaF (1,500 ppm) and sodium dodecyl sulfate (SDS; 2 wt%), a common component in the toothpastes that caused the most severe degradation. The findings indicated that SDS accelerates the degradation of CAD-CAM resin composites in the presence of NaF, suggesting that toothpastes containing both NaF and SDS contribute to the deterioration of surface properties.

The antiarrhythmic drug amiodarone is toxic to yeast cells due to provoking Ca2+ entry into cytosol. Here we show that in Ogataea parapolymorpha, the loss of Cch1 or Mid1, which are the primary components of the high-affinity Ca2+ uptake system (HACS), leads to a delay in the rise of cytosolic Ca2+ concentration ([Ca2+]cyt) in response to amiodarone. This has negligible effect on the ability of the strain with the unaffected Ca2+ sequestration system to grow in the presence of amiodarone. Inactivation of the PMC1 gene encoding the Ca2+ ATPase involved in the cytosolic Ca2+ sequestration in the vacuole dramatically increases sensitivity to amiodarone, while inactivation of CCH1 or MID1 suppresses it. This correlates with a substantially lower [Ca2+]cyt rise in response to amiodarone when the genes encoding the HACS components are inactivated in the mutant lacking Pmc1. Similarly to sodium dodecyl sulfate, which has also been shown to increase [Ca2+]cyt, amiodarone causes activation of the Hog1 protein kinase involved in the cell cycle regulation. The role of HACS in the amiodarone-induced Ca2+ influx is discussed.

Considering their safety, low cost, and environmental friendliness, aqueous zinc-ion batteries (AZIBs) have become increasingly attractive for grid-scale energy storage applications. However, AZIBs suffer poor cyclability due to severe dendrite growth, self-corrosion, hydrogen evolution, and irreversible side reactions at Zn anodes. Electrolyte additives are one of the most common strategies for suppressing these issues. In this study, we demonstrate the combination of La(NO3)3 and sodium dodecyl sulfate (SDS) as electrolyte additives for stabilizing Zn metal anodes. An interaction between La(NO3)3 and SDS results in the formation of a new La3+-SDS complex, which facilitates preferential Zn2+ deposition on the (002) plane, leading to a dendrite-free Zn anode. The adsorption of the sulfonate groups, along with the hydrophobic alkyl groups of SDS present on the Zn surface, effectively restricts the proximity of free water, thus suppressing adverse reactions on the Zn anode. Furthermore, synergistic interaction between Zn2+, La3+, and SDS can effectively repair defects in metal oxide passivation layers, preventing the dissolution of the Zn electrode and oxygen reduction sites. Notably, the incorporation of La(NO3)3 and SDS into the electrolyte significantly extends the cell lifespan to over 1430 h at 1 mA cm-2 and 720 h at 5 mA cm-2 in Zn symmetric cells. Meanwhile, the Zn||Cu asymmetric cell reveals high reversibility with a remarkable Coulombic efficiency of 99.3% at 1 mA cm-2. This study offers a novel perspective on electrolyte regulation in AZIBs, highlighting the potential synergistic effects of different types of additives for stabilizing Zn anodes in aqueous electrolytes.

Single crystals grown from aged semiconducting single-walled carbon nanotubes (SWCNTs) aqueous solution (thin plate shape single crystals from 7 years old sodium dodecyl sulfate (SDS) dispersed arc discharge semiconducting SWCNTs and needle shape single crystals from over 12 years old sodium cholate (SC) dispersed arc discharge semiconducting SWCNTs) were obtained. Their crystallographic structures were refined from their x-ray synchronic patterns to be two SDS molecules co-crystallized with two water molecules and one dodecanol, and cholic acid hemihydrate, respectively. The thin plate single crystals were further characterized with nuclear magnetic resonance spectrum and mass spectrum to be complex of 2 SDS to 1 dodecanol. No dodecanol was detected using gas chromatography mass spectrum in the extract that extracted from the mother solution of thin plate single crystals grown in using chloroform. This indicates the dodecanol might be from the hydrolysis of SDS in rod shape structure with encapsulated semiconducting SWCNTs catalyzed by locally enhanced acidity, which is induced by the salt repelling trait of carbon nanotubes. Similarly, loosely packed SC molecules around semiconducting SWCNTs were acidified to form tightly bounded cholic acid tetramers that further tightened by hydrogen bonding to form 65 symmetry helices around semiconducting SWCNTs.

Energy flow is the hidden force that drives vital processes in biomolecules, from catalysis to molecular transport. While heme proteins have long been the centerpiece of studies on rapid energy dissipation, ultrafast energy flow in non-heme proteins (and those lacking intrinsic cofactors), some of which are key players in drug delivery and nutrient transport, remains relatively less explored experimentally. Here, we set out to uncover energy flow in human serum albumin (HSA), bovine serum albumin (BSA), and β-lactoglobulin (β-LG) by incorporating hemin chloride as the photoreceptor and utilizing femtosecond transient absorption spectroscopy. HSA and BSA, despite having structural similarities, showed different hemin relaxation behaviors, arising from subtle variations in their hemin-binding pocket environments. In β-LG, on the other hand, hemin binds at the monomer-monomer interface (thereby disrupting the native dimer state) and hence remains the most exposed to the surrounding solvent bath, exhibited a slower energy transfer. To gain a better understanding, we also investigated hemin dynamics in aqueous and organic solvents as well as in micellar environments (normal and reverse micelles), uncovering that hydrophobic solvents sped up energy relaxation while water slowed it down. Surfactants such as SDS (sodium dodecyl sulphate), Brij 35 (polyoxyethylene(23)lauryl ether), and CTAB (cetyltrimethylammonium bromide) offered distinctive handles on factors affecting energy flow, while reverse micelles enabled a more controlled energy dissipation under varying degrees of confinement, mimicking biological environments. These findings illuminate how subtle shifts in external environments can dramatically reshape energy dynamics. Considering the importance and universality of energy flow, such perceptions are fundamental to gaining a broader understanding of the manner in which the physiological interior succeeds in driving a vast array of biological processes at their optimum.

Background: Numerous protocols exist concerning the decellularization of the esophagus, a potential alternative to the classical surgical approach for the reconstruction of the digestive tract after esophagectomy. This systematic literature review (SLR) aimed to provide an overview of the effectiveness of the current protocols. Methods: This SLR was conducted in PubMed, EMBASE, and Scopus until September 2025. Study selection, data extraction, and quality assessment were performed by two independent reviewers according to the inclusion/exclusion criteria. Results: A total of 2494 references were screened after removing duplicates. Among these references, 26 articles were included. The large majority of studies (24/26) used Sodium Dodecyl Sulfate (SDS) or Sodium DeoxyCholate (SDC), and the most common physical method was the cannulation of the esophagus (17/26). The animal model was very heterogenous. All protocols except one showed no residual cell nuclei, with only 5/19 papers confirming a satisfactory residual amount of DNA. The assessment of the extracellular matrix (ECM)—mostly qualitative—revealed global preservation but with a systematic loss of glycosaminoglycans (GAGs). Conclusions: The decellularization of the esophagus is feasible, but the definition of the optimal protocol to achieve this goal remains difficult because of the important heterogeneity among the different studies.
