A graph G = (V,E) is well-dominated if every minimal dominating set is a minimum dominating set. That is, gamma(G) = Gamma(G). This condition may be weakened by stipulating that only non-minimal dominating sets contain minimum dominating sets. Under this condition, gamma(G) is not equal to Gamma(G) and there may exist minimal dominating sets of cardinality greater than gamma(G). Such graphs are called weakly well-dominated graphs. A study of these graphs is made in this paper.
Electrocatalytic determination and photocatalytic degradation of hazardous environmental pollutants using efficient nanocomposite materials are significant methods to decrease adverse effects of the contaminants. Herein, zinc oxide integrated carbon nitride (ZnO@CN) nanocomposite was synthesized by co-precipitation method and used equally bifunctional catalyst towards the detection of catechol (CT) and degradation of Rhodamine B (RhB) dye. The as-prepared nanocomposite was characterized thoroughly by XRD, FT-IR, UV-DRS, SEM and EDX spectroscopic and microscopic techniques. The nanocomposite act as an electrocatalyst for detection of catechol with 0.024 mu M LOD, 0.01-268 mu M wide linear response range and 0.367 mu A mu M-1cm-2 sensitivity respectively while acting as a photocatalyst to degrade RhB with efficiency of 95.3 % within 40 minutes under visible light irradiation. Additionally, catalyst has superior reusability around five cycles, stability over 20 days, and reproducibility of 4 different modified electrodes towards degradation and detection reactions. From these results, we confirmed ZnO@CN nanocomposite is one of the auspicious candidates for removal of pollutants from the aquatic environment.
Fungal endophytes can be identified in a wide range of plant species which help to protect from both abiotic and biotic stressors. This research focused on using high-throughput sequencing (HTS) analysis to gain insight into the foliar endophytic fungal diversity between Morinda tinctoria and Pithecellobium dulce. The study obtained a total of 118,547 sequencing reads, which were grouped into 266 Operational Taxonomic Units (OTUs) with a 97% similarity threshold. M. tinctoria had more OTUs than P. dulce. Alpha diversity results show that both plant species support varied microbial communities with similar but distinct biodiversity profiles. The Shannon index revealed that M. tinctoria had considerably more fungal diversity than P. dulce. The correlation matrix and PCoA depicts the pairwise correlations between several soil metrics such as the total nitrogen level, entire phosphorus, overall potassium, and the electrical conductivity, total carbon from organic matter, pH levels, manganese, iron, zinc, copper, and boron. The OTUs were classified into 5 phyla, 18 classes, 40 orders, 70 families, and 36 genera, where the phylum Ascomycota has a relative abundance of (50–55%), followed by Basidiomycota at (55–60%). The most abundant genera were Wallemia (30–35%), Saitozyma (30–40%), and Talaromyces (20–25%), with average relative abundances. Unassigned genera show a significant proportion of fungal taxa that are still taxonomically unclear. A comparative analysis has been performed between the two plants, M. tinctoria has a higher fungal diversity, which is frequently associated with increased ecological stability, disease resistance, and better functional relationships with the host plant.
This study looks at the formation of g-C3N4@CuNi nanoparticles with good electrocatalytic properties. UV-DRS, FT-IR, XRD, SEM, EDX, XPS, BET, and HR-TEM techniques were used to characterise the produced g-C3N4@CuNi nanoparticles. The energy gap values like 3.4 eV, 3.2 eV, and 2.7 eV for g-C3N4, CuNi bimetallic, and gC3N4@CuNi NPs, respectively. Electroanalysis on core-shell nanoparticles demonstrated dopamine's electrocatalytic activity. The sensor has a detection limit (S/N = 3) of 0.001 M, a sensitivity of 198.12 mu A mM-1 cm-2 and a high recovery in real sample analysis, indicating its practical viability. A novel electrochemical sensor could be created by combining g-C3N4 and CuNi bimetallic NPs.
The objective of this work was to assess the bioactive potential of endophytic fungi, Colletotrichum brevisporum (JPSK3), Pestalotiopsis microspora (JPSK19), and Guignardia mangiferae (JPSK25), from Bergenia ciliata. The antibacterial effects were determined by the well diffusion technique against human pathogens (Staphylococcus aureus, Escherichia coli, Bacillus cereus, and Salmonella typhi) and they showed good activities. In the antioxidant assay, the fungal extract P. microspora shows higher free radical scavenging effects in 2,2-diphenyl-1-picrylhydrazyl (82.48%), hydrogen peroxide (84.91%), superoxide (78.85%), and reducing power absorbance of 0.125 at a dosage of 125 g/mL than other two fungi. The fungal extract was also subjected to phenol and flavonoid quantifications. The fungus P. microspora shows the highest phenol (89.56 0.03 mg of GAE/g of extract) and flavonoid (51.52 0.69 mg of quercetin equivalents/g of extract), respectively. The chemical composition of abundant biologically active compounds was determined by gas chromatography-mass spectrophotometry (GC-MS). Furthermore, it was confirmed through spectral and analytical analysis (thin layer chromatography, ultraviolet, Fourier transform infrared spectroscopy, high-performance liquid chromatography, GC-MS, and nuclear magnetic spectroscopy). In P. microspora, the compound phenol, p-tert-butyl (C10H14O), was confirmed for the first time. This fungal compound could be a potential alternative medicine in the future. This is the first work on endophytic fungal studies of ethnomedicinal plant Bergenia ciliata.
