Carthamin, a red pigment obtained from safflower (Carthamus tinctorius L.) pulp, is widely used in food colorants, dyes and medicines. This study was carried out to obtain red pigments in various forms by extraction and purification from industrial waste of safflower pulp. Green solvents, organic solvents and acidic/a…

This study investigates the influence of solvent physical properties on cavitating flow dynamics in micro-scale hydrodynamic cavitation (HC) reactors using green solvent systems (de-ionized water (DIW)–isopropyl alcohol (IPA) and DIW–ethanol mixtures). The primary focus of this work is to resolve cavity dynamics in th…

Thin film microextraction (TFME) greatly benefits from extractive phases with a large surface area, since this feature is paramount for rapid and effective analyte sorption. One of the techniques that can be used for preparation of TFME samplers with large extractive phase surface area is electrospinning. The traditio…

This study has developed a modular centrifuge system that is portable, low-cost and does not require electricity. It can be produced using 3D printing technology. The project aims to provide an economical, energy-independent solution for separating biological and chemical samples, particularly in environments where ac…

Electro-blowing (EB) has emerged as a transformative high-throughput technology for nanofiber fabrication, bridging the gap between laboratory-scale electrospinning and industrial production requirements. However, the simultaneous interaction of electrostatic forces and high-velocity air streams creates a complex mult…

Polymer mats are prepared by electrospinning and coated with a single-walled carbon nanotube dispersion by simultaneous electrospraying, creating a conductive nanotube network on and between fibres. The resulting mats act as p-type thermoelectric materials due to the properties of the nanotubes and also serve as highl…

ABSTRACT An one‐step procedure of simultaneous electrospraying and electrospinning is employed to produce fiber mats of a poly(vinylidene fluoride) (PVDF)/thermoplastic polyurethane (TPU) blend and polylactide (PLA) coated with singlewalled carbon nanotubes (SWCNTs). Thermoelectric investigation of the mats yielded Se…
