Solid acidity of MoO3 synthesized by solution combustion method and acetalization of formaldehyde using it
Abstract: MoO 3 nanoparticles were synthesized via solution combustion approach. Ammonium nitrate was used as oxidant and ammonium molybdate as fuel in combustion reaction. XRD, FTIR and Raman spectroscopy results showed that MoO 3 nanoparticles were successfully synthesized by the solution combustion reaction. The SEM analysis showed that synthesized MoO 3 nanoparticles have rod-like shape with width and thickness of 50-200nm and length of 0.2-1μm, respectively. The XRD pattern and morphology …

Optimizing Chromatographic Techniques for Comprehensive Paraben Analysis to Enhance Safety in Consumer Products
Abstract: Parabens (PBs), such as methylparaben (MePB), ethylparaben (EtPB), propylparaben (PrPB), and butylparaben (BuPB), are widely used as preservatives in pharmaceuticals, food, and personal care products due to their antibacterial properties. However, there are growing worries about their potential to disrupt hormonal functions, which has led to stricter regulations. This study focuses on creating a robust high-performance liquid chromatography (HPLC) method for quickly measuring all four parabens in consumer goods. We …

Synthesis and Characterization of Certain Biodegradable Chitosan/Lactic Acid-based Polyester Blend Films
Abstract: AbstractBiodegradable blend films based on chitosan with poly(ethylene glycol lactate-co-ethylene glycol terephthalate), PEGLT and poly(butylene lactate-co-butylene succinate), PBLSA, were prepared by solution-mixing and film-casting method. The main objective of this investigation was the study and characterization of chitosan/lactic acid-based polyester blends which are useful as bio-packaging material for potential food applications. The first part of the investigation was related to the synthesis and characterization of polyesters, PEGLT and PBLSA by …

Partial Characterization of Crude Lipase from Mutant Soil Fungal Isolate
Abstract: Lipases are cluster of enzymes which cleaves oils and fats. Characterization properties oflipases have been studied in the present investigation because they play an imperative role inseveral industrial applications. The present lipase obtained from soil fungal strain named asEMS5%-60min exhibited optimum activity at pH 7.0 (24.90±0.25 IU/ml/min) and 37ºC (20.28±0.51IU/ml/min). In pH stability profile, the enzyme was found stable in alkaline pH range withhighest activity (13.08±0.07 IU/ml/min) at pH 9.0. …
