Description

General description

EMPLURA^® is our low-cost alternative to high-purity qualities. With EMPLURA we offer a range of solvents for a plurality of basic applications in non-regulated industries and for less demanding applications, preparative laboratory work and cleaning purposes. EMPLURA solvents provide adequate specifications with the most important parameters.

Application

• Self-Assembly of Polyoxometalate-Based Nanoparticle Surfactants in Solutions: Highlights the use of Tetrahydrofuran as a critical solvent in the synthesis and self-assembly of polyoxometalate-based nanoparticles, exploring applications that could impact multiple fields including polymer research, drug delivery systems, and nanostructured materials (Xia et al., 2024).


• Highly sensitive fluorescence turn-OFF and reversible chemical sensor for Hg(2+) ion based on pyrene appended 2-thiohydantoin: Tetrahydrofuran is used as a key solvent in the development of a novel fluorescence-based chemical sensor for mercury detection, demonstrating its application in environmental monitoring and safety in laboratory settings (Gawas et al., 2024).


• Effect of Plasma pretreatment and Graphene oxide ratios on the transport properties of PVA/PVP membranes for fuel cells: This research employs Tetrahydrofuran as a processing solvent in the creation of polyvinyl alcohol/polyvinylpyrrolidone membranes enhanced with graphene oxide, focusing on improvements in ion transport for fuel cell applications (Abdel-Hamed et al., 2024).


• Optimized Incorporation of Furan into Diketopyrrolopyrrole-Based Conjugated Polymers for Organic Field-Effect Transistors: Utilizes Tetrahydrofuran as a solvent to aid in the synthesis of novel conjugated polymers, potentially leading to advancements in organic electronics and polymer research (Neu et al., 2024).
