The selectivity of the electrodes in a perovskite solar cell device strongly affects the device's performance and stability. This can be achieved by inserting semiconductor thin films with suitable energy levels and electrical conductivity between the perovskite active layer and the electrodes in the device. Different types of metal oxide-based interlayers with large variations in their electrical properties have been utilized as electron and hole transport layers. In this regard, a nickel oxide hole transport layer has demonstrated excellent results. The nickel oxide layer, which is about 10 nm thick, is fabricated by sputtering deposition or by a nickel oxide precursor with a high-temperature post-thermal annealing treatment in air between 200 °C and 300 °C. The perovskite active layer can be processed by wet coating methods and thermal treatments at much lower temperatures. It is, therefore, more cost-effective and product-compatible to fabricate solution-processed nickel oxide at room temperature. Here, we report a stable dispersion of nickel oxide nanoparticles in water processed at room temperature. The nickel oxide film was coated in air without any need for post-treatment, leading to a condensed nickel oxide (NiOx) film with suitable properties acting as an optimum hole transport layer for perovskite solar cells.

The pathogenesis of this bacterium is due to its virulence toxins, which inactivate the small GTPases from the Rho and Ras families in host cells, leading to the establishment of <em>Clostridioides difficile</em> infection. In a bid to avert this infection, compounds from SuperNatural 3.0 were screened against the catalytic glucosyltransferase domains of TcdA and TcdB using molecular docking analysis. The enzymes and the compounds were imported into the PyRx virtual screening software and docked accordingly. Post-docking interactions were visualized using Discovery Studio software. The binding energies resulting from the interaction of the compounds and the enzymes were within the range of −8.9 to −11.4 kcal/mol and −7.6 to −11.2 kcal/mol for TcdA and TcdB respectively, suggesting fairly strong binding affinities. Ligands that have the potential to be considered for drug discovery have binding energy less than −6.0 kcal/mol (or −8.0 kcal/mol in some cases). This is associated with the hydrogen bonds and other interactions between the molecules and the amino acids found within the toxins. The pharmacokinetic profiling revealed the compounds to be relatively safe, with SN0161212, SN0032215, and SN0084749 passing Lipinski's rule of five, with none predicted to cause human hepatotoxicity or drug-induced liver injury. The findings from this research suggest that the SuperNatural 3.0 compounds (SN0161212, SN0032215, and SN0084749) possessed the potential to inhibit <em>Clostridioides difficile</em> toxins.

The research was conducted in the nursery of Purwodadi Botanic Garden, Pasuruan, East Java, which has a lowland and dry tropical climate. The ecophysiological characteristics were observed 16 weeks after the seedlings germinated, including the traits of leaf, stem, root, and relative growth rate. Data were analyzed using analysis of variance (ANOVA), Pearson correlation, and principal component analysis (PCA). The results showed that each fruit species at the seedling stage has typical ecophysiological characteristics. Durian dominated traits related to leaf and stem. Java plum had the highest specific root length. Mango exhibited the highest relative growth rate. Two characters were identified as crucial determinants for predicting optimal growth performance at the seedling stage, i.e., stem weight ratio and specific leaf area. The PCA biplot resulted in three groups. Durian, kecapi, and rambutan (Group I) are fast-growing, shade-adapted, and low-flammable species. Java plum and longan (Group II) are drought-adapted species. Matoa and mango (Group III) are competitive and resilient to physical hazards species.

The properties (bias and mean squared error) are derived from the first-degree approximation. The suggested estimators are useful when working with uncertain, unclear, neutrosophic-type data. The best possible values of the defining scalars characterizing constants and the minimum neutrosophic mean squared error (MSE) for the suggested estimators are determined for these ideal values. Neutrosophic estimators outperform their classical counterparts because the existing estimated interval includes the minimum MSE when estimating the population mean.
