Biodiesel presents a favourable economic outlook and environmental benefits, yet it faces limitations such as diminished calorific value and suboptimal combustion characteristics. Recent research focuses on enhancing biodiesel performance using nanoparticles and thermal barrier coatings. This study investigates non-edible biodiesel from Momordica seed oil, tested on a single-cylinder diesel engine.

An innovative silica-bonded -(propylaminobenzene)-sulfonic acid (SBPASA) catalyst was synthesized by immobilizing metanilic acid onto silica and characterized using advanced techniques, including FTIR, XRD, SEM/EDX, Raman spectroscopy, UV-visible analysis, and BET surface area analysis. The catalyst exhibited a high surface area of 306.9 m/g, an optimal mesoporous diameter of 31.

Advancements in nanotechnology, particularly the use of bionanofertilizers, show promise for sustainable agriculture by enhancing soil health and reducing reliance on conventional fertilizers. This study explored the impact of a bioslurry and biogenic zinc oxide (ZnO) nanoparticle formulation on microbial diversity in the rhizosphere of Vigna radiata (mung bean) using 16S rRNA sequencing. High-quality reads from both untreated and treated soil samples revealed a dominance of Archaea, though its proportion was reduced in the treated sample (66% in untreated, 58% in treated).

A UV-HPLC method optimized by Box-Behnken design model was developed to determine caffeine in pharmaceutical preparations and urine samples. The chromatographic conditions followed were mobile phase: methanol/water/ citrate buffer (pH 4.6) (40:25:35, v/v/v),AcclaimDionex C18 column (ODS 100A˚, 5 µm; 4.

In this study, we investigated the intricate interplay between Trichoderma and the tomato genome, focusing on the transcriptional and metabolic changes triggered during the late colonization event. Microarray probe set (GSE76332) was utilized to analyze the gene expression profiles changes of the un-inoculated control (tomato) and Trichoderma-tomato interactions for identification of the differentially expressed significant genes. Based on principal component analysis and R-based correlation, we observed a positive correlation between the two cross-comaparable groups, corroborating the existence of transcriptional responses in the host triggered by Trichoderma priming.

The high-performance liquid chromatographic (HPLC) and kinetic spectrophotometric methods were established to compute valsartan (VAL) in pharmaceutical formulations. The spectrophotometric procedures adopted initial rate, fixed time, and equilibrium strategies to assess VAL. The method was based on the carboxylic acid group of the oxidized VAL with a mixture of potassium iodate (KIO) and potassium iodide (KI) at room temperature, producing a stable, yellow-coloured absorb at 352 nm.
