A fast, sensitive, and green reverse-phase “high-performance thin-layer chromatography” approach for the simultaneous estimation of ibuprofen (IBF), caffeine (CAF), and paracetamol (PCM) in marketed formulations was established and verified in this study. The binary combination of acetone and water (80:20 v/v) was used as the green eluent system. The current method’s greenness was predicted using four different approaches, namely National Environmental Method Index, Analytical Eco-Score (89), ChlorTox (1.08 g), and the Analytical GREENness (83) approaches, which demonstrated an outstanding greener profile. The present approach was linear in the range of 25–800 ng·band−1 for the simultaneous estimation of IBF, CAF, and PCM. In addition, the current method was accurate (% recoveries = 100 ± 2), precise (%CV < 2%), robust (%CV < 2), sensitive (LOD = 1.13–2.71 ng·band−1 and LOQ = 3.39–8.10 ng·band−1), and green. The amount of IBF, CAF, and PCM in commercial tablets was determined to be 99.51%, 98.25%, and 100.64%, respectively. The present method for the simultaneous determination of IBF, CAF, and PCM in marketed tablets is supported by these data. The findings of this study suggested that the current approach may be consistently applied to analyze IBF, CAF, and PCM in marketed tablets.

Herein, capsaicin nanoparticles (NPs) were prepared by two different methods, namely, evaporative precipitation of nanosuspension (EPN) and anti-solvent precipitation with a syringe pump (APSP). The nanoparticles of the necessary sizes were obtained after optimizing experimental parameters such as the solvent-to-anti-solvent ratio and stirring speed. They had spherical shapes and an average diameter of 171.29 ± 1.94 and 78.91 ± 0.54 nm when prepared using the EPN and APSP methods, respectively. Differential scanning calorimetry and an X-ray diffractometer showed that the capsaicin crystallinity decreased. FTIR results showed that the NPs were produced with their original configuration and did not result in the synthesis of any additional structures. The NP formulation had a desirable drug content. They surpassed the unprocessed drug in solubility and displayed the desired stability. Capsaicin NP cream showed many folds of enhanced analgesic, anti-inflammatory, and antimicrobial effects compared to unprocessed capsaicin.

The aim of this study is to address the growing concern about microplastics in the ocean and their potential harm to human health through ingestion. The MPs issue is largely a result of the increasing demand for electronic devices and their components. To tackle this challenge, the research aimed to develop a green polymer electrolyte that used glycerol as a plasticizing agent to improve ionic conductivity. The polymer host included chitosan and polyvinyl alcohol and was composed of sodium acetate. To evaluate the performance of the polymer electrolyte, various analytical techniques were used, including impedance and electrochemical studies. The ionic conductivity of 7.56 × 10−5 S·cm−1 was recorded. The dielectric property study confirmed the ionic conduction process in the system and revealed the existence of non-Debye type relaxation, as indicated by asymmetric peaks of tanδ spectra. The alternating conductivity exhibits three distinguished regions. The polymer electrolyte was discovered to be electrochemically stable up to 2.33 V and capable of storing energy as a non-Faradaic electrochemical double-layer capacitor (EDLC). The cyclic voltammetry pattern is a leaf like shape. The EDLC was able to be charged and discharged up to 1 V, and it showed cyclability and could be used in low-voltage applications.

Low-energy separation of potable water from urine is an important area of research, particularly if humans hope to transcend their earth-bound origins. The high cost of water in rocket payloads means that it must be recycled and the byproducts of the crew used productively. Direct Contact Membrane Distillation (DCMD) can use low heat sources to separate water from urea, which can then be used as a plasticizer in regolith-based cement to make it more workable. In the present study, traditional cement curing was compared to vacuum curing for regolith-based cement where artificial urine, concentrated using DCMD, was added as a plasticizer. Increases in workability were found for increasing concentrations of urea. Porosity also tended to increase with increasing urea concentration. Surprisingly, Lunar Highlands Simulant regolith-based batches with urea that were cured under vacuum showed higher compressive strengths than those cured traditionally. No literature is available for DCMD use with urine, indicating that this research is novel and could have widespread applications, such as in desert environments or public urinals.

This research delves into the effects of different alkalization treatment approaches on the mechanical characteristics of epoxy matrix composites that are reinforced with natural bamboo fibers and enriched with egg and coconut shell powders as fillers. Various weight ratios of fibers and fillers were investigated, specifically at 5%, 10%, 15%, 20%, 25%, and 30%. The study assessed mechanical properties such as tensile strength, flexural behavior, microhardness, and impact resilience. Findings indicate that composites with alkali-treated fibers demonstrate superior mechanical performance (49.28 MPa of tensile, 57.33 MPa of flexural 89 HV of hardness, and 1.3 kJ·m−2 of impact) compared to untreated counterparts. Particularly noteworthy is the significant improvement in fracture toughness observed with the inclusion of 20% hybrid laminates, surpassing the performance of existing biomaterial-based composites. This heightened toughness is attributed to the optimized composition of fibers and enhanced water absorption capabilities. Conversely, the incorporation of 25% and 30% hybrid composites led to a decrease in mechanical strength (38.65 MPa of tensile, 46.7 MPa of flexural, 72 HV of hardness, and 1.19 kJ·m−2 of impact) due to the formation of additional interfacial contacts, pores, and voids within the polymeric matrix.

Copper oxide nanoparticles (CuO NPs) were synthesized using ayurvedic medicine septilin. The septilin-mediated CuO NPs were characterized using UV–Vis, fourier-transform infrared spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The average particle size of CuO NPs was 8 nm as evident from TEM. Minimum inhibitory concentration of CuO NPs against Escherichia coli, Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), and Candida albicans was found in the range of 1–2.5 mg·mL−1. CuO NPs dose-dependently decreased the biofilm formation from 0.0315 to 2 mg·mL−1, at the highest dose of 2 mg·mL−1 of CuO NPs; 92.91%, 79.84%, and 71.57% decrease in biofilm was observed for P. aeruginosa, MRSA, and C. albicans, respectively. Down-regulation of biofilm upon treatment with nanoparticles (NPs) was also observed by SEM analysis. SEM analysis also showed the change in morphological structure, and deformities in bacterial and fungal cells upon treatment of NPs. Furthermore, the anticancer efficacy of NPs was assessed using colon cancer (HCT-116). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay clearly showed the anticancer potential of NPs, as the concentration of CuO NPs increased, the number of viable cells decreased. The produced CuO NPs have promise for future investigations in many biological and therapeutic domains, including the treatment of microbial biofilm infections, as well as the inhibition of cancer cell growth.

Herein, we used the aqueous extract of Uncaria tomentosa L. barks (Cat’s claw bark [CCb]) for the biofabrication of silver nanoparticles (CCb-Ag-NPs). The effects of different parameters (Uncaria tomentosa L. aqueous extract, silver nitrate [AgNO3] ratio, temperature, and pH) on the formation of the nanoparticles were investigated using UV scan as a preliminary tool for the detection of surface plasmon resonance of CCb-Ag-NPs. The optimal ratio was 1:7 (Uncaria tomentosa L. extract: 1 mM AgNO3 solution). Fourier-transform infrared spectroscopy revealed the functional groups of both CCb extract and the CCb-Ag-NPs, whose dispersion and quasispherical morphologies were characterized using scanning electron microscopy and transmission electron microscopy. Particle sizes ranged from 19.2 to 38.5 nm. The zeta potential of CCb-Ag-NPs was −34.44 mV. According to energy-dispersive X-ray analysis, the CCb-Ag-NPs contained 28.87% silver. The formation of Ag-NPs was also confirmed by X-ray diffraction pattern analysis. Pristine CCb-Ag-NPs showed antibacterial activity against three pathogenic bacterial strains: Escherichia coli (ATCC 25922), E. coli (ATCC 8739), and Pseudomonas aeruginosa (ATCC 90274). Antibacterial activity increased significantly after loading CCb-Ag-NPs on antibiotic discs containing meropenem and cefoxitin. Low concentrations of CCb-Ag-NPs also enhanced the germination percentage, coleoptile length, and radical root length of Triticum aestivum.

This work concentrated on the decoration of AgNPs to yellow phosphorus slag (YPS) using both chemical (NaBH4) and biological (Areca catechu nut and Jasminum subtriplinerve leaf extracts) reducing agents, as well as its use as antibacterial and enhancement additives for organic coatings based on acrylic emulsion resin. It is the first study about the decoration of AgNPs on the surface of YPS using bio-reduction agents (A. catechu nut and J. subtriplinerve leaf extracts). The characteristics of YPS decorated by AgNPs (YPS@AgNPs) were determined using attenuated total reflectance infrared spectroscopy, scanning electron microscopy, X-ray diffraction, ultraviolet-visible spectroscopy and dynamic light scattering methods. To quantify the amount of AgNPs in YPS@AgNPs, atomic absorption spectroscopy was used. The results of YPS@AgNPs fabrication confirmed that the above green reduction agents had a higher efficiency and were more suitable than the chemical reduction agent (NaBH4). Moreover, the ability to inhibit the growth of bacteria strains of YPS@AgNPs using the J. subtriplinerve leaf extract as a reducing agent gave the best result among the three agents. In particular, the bactericidal activity of YPS@AgNPs against the new marine bacterium, Pseudomonas stutzeri B27, was evaluated, and it was found that YPS@AgNPs can inhibit the growth of an antibiotic-resistant bacterium, P. stutzeri B27. They enhance not only the mechanical properties but also the bactericidal ability of the water-borne acrylic resin coating.

Multifunctional nanocomposites (NC) can greatly enhance therapy outcomes by reducing tumor proliferative potential. We created a novel class of Zn_Mn_CMC_FA_sesamol NC in the current work to combat breast cancer (MDA-MB-231) cells. To understand how zinc (Zn), manganese (Mn), carboxymethylcellulose, and folic acid (FA) interact with sesamol, UV-Visible spectrophotometer and Fourier Transform Infrared spectroscopy were used to analyze the absorption behavior of the synthesized NC. The particle size of NC was confirmed by X-ray diffraction and dynamic light scattering. Scanning electron microscopy was used to assess the morphological features of these NCs. photoluminescence spectrum was used to analyze the optical and electron transition molecules of the sample. In addition to MTT analysis, acridine orange/ethidium bromide (AO/EtBr) analysis of reactive oxygen species (ROS) and nuclear staining with 4′,6-diamidino-2-phenylindole as well as flow cytometry were used to confirm the apoptotic activity of Zn_Mn_CMC_FA_sesamol NC on MDA-MB-231 cells. The results showed significant cytotoxicity, apoptosis induction on AO/EtBr, and increased ROS production in treated cells compared to control cells. The cell cycle analysis revealed that NCs triggered apoptosis and arrested the cell cycle in G0/G1 phases. As a conclusion, the created NC serves as a versatile platform for the successful molecularly targeted chemotherapeutic treatment of cancer.

We created a novel class of Zn_Mn_CMC_FA_sesamol NC in the current work to combat breast cancer (MDA-MB-231) cells. To understand how zinc (Zn), manganese (Mn), carboxymethylcellulose, and folic acid (FA) interact with sesamol, UV-Visible spectrophotometer and Fourier Transform Infrared spectroscopy were used to analyze the absorption behavior of the synthesized NC. The particle size of NC was confirmed by X-ray diffraction and dynamic light scattering. Scanning electron microscopy was used to assess the morphological features of these NCs. photoluminescence spectrum was used to analyze the optical and electron transition molecules of the sample. In addition to MTT analysis, acridine orange/ethidium bromide (AO/EtBr) analysis of reactive oxygen species (ROS) and nuclear staining with 4′,6-diamidino-2-phenylindole as well as flow cytometry were used to confirm the apoptotic activity of Zn_Mn_CMC_FA_sesamol NC on MDA-MB-231 cells. The results showed significant cytotoxicity, apoptosis induction on AO/EtBr, and increased ROS production in treated cells compared to control cells.

Selenium (Se) is an important trace element that is involved in controlling oxidative stress and inflammatory disorders. Gouty arthritis is the inflammation and pain within the joints and tissues caused due to the accumulation of monosodium urate (MSU) crystals. This study aimed to investigate the antigout, antioxidant, anticoagulant, and thrombolytic potential of ascorbic acid-mediated Se nanoparticles (A-SeNPs). Different analytical techniques were used to investigate the formation of A-SeNPs. The antigout potential of the nanoparticles was carried out using MSU crystal dissolution, uric acid (UA) degradation assay, and xanthine oxidase inhibition (XOI). A-SeNPs exhibited excellent antihyperurecemic activity in a concentration-dependent manner. It was observed that at the tested concentration of 20 mg·mL−1, the A-SeNPs demonstrated significant breakage and dissolution of MSU crystals and resulted in UA degradation of 67.76%. Similarly, A-SeNPs resulted in 76% XOI with an excellent IC50 of 140 µg·mL−1. Furthermore, considerable antioxidant activity was noted for the A-SeNPs as evaluated with multiple antioxidant assays. Finally, the NPs were found to have significant anticoagulant and thrombolytic potential. Thus, it was concluded that A-SeNPs have potent antihyperuricemic, antioxidant, anticoagulant, and thrombolytic activities, making them an ideal choice for future biomedical applications.
