Ag–Cu₂O Supported Biomass-Derived rGO for Catalyzing Suzuki–Miyaura Cross-Coupling

Langmuir, Journal Year: 2024, Volume and Issue: 40(35), P. 18473 - 18485

Published: Aug. 20, 2024

The search for cost-effective, efficient, and ecofriendly heterogeneous catalysts the Suzuki-Miyaura reaction is crucial due to challenges with expensive, toxic homogeneous catalysts. This study centrally aims at crafting a pioneering green catalyst by adorning reduced graphene oxide (rGO), sourced from basil seeds (

Evaluating the Effectiveness of Cellulose-Based Surfactants in Expandable Graphite Wood Coatings

Polymers, Journal Year: 2024, Volume and Issue: 16(19), P. 2832 - 2832

Published: Oct. 7, 2024

This study deals with the design of modern environmentally friendly and non-toxic flame retardants based on expandable graphite 25 K + 180 (EG) modified by cellulose ethers (Lovose TS 20, Tylose MH 300, Klucel H) nanocellulose (CNC) that are biocompatible wood and, therefore, a prerequisite for an effective surfactant connecting EG to wood. The effectiveness formulations surfactants was verified using radiant heat source test. cohesion coating surface expanded layer were also assessed. fire efficiency varied greatly. Still, in combination EG, they all able provide sufficient protection-the total relative mass loss was, cases, range 7.38-7.83% (for untreated it 88.67 ± 1.33%), maximum burning rate decreased tenfold compared wood, i.e., 0.04-0.05%·s

Chitosan/Microcrystalline Cellulose Overlaid rGO/Fe₃O₄ Films: Broadband Dielectric Spectroscopy Investigations

ECS Journal of Solid State Science and Technology, Journal Year: 2024, Volume and Issue: 13(9), P. 093003 - 093003

Published: Sept. 2, 2024

Hybrid and straightforward inorganic/organic composites that can be used simultaneously for energy storage are reported. Films from chitosan (Cs) with microcrystalline cellulose (MCC) implanted reduced graphene oxide (rGO) and/or magnetic Fe 3 O 4 nanoparticles were fabricated. The reinforcement of the Cs/MCC films rGO /or was studied through Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy dispersive spectroscopy. In addition, their magnetic, conductivity, dielectric constant, loss behaviors studied. investigations two loaded have supper paramagnetic behavior. saturation magnetization decreased presence rGO. At lower frequencies, contribution charge transport interfacial polarization causes a sudden nearly linear increase in permittivity decreasing frequency. Unfortunately, no indication electrode found, which reduces ability prepared composition to store electrical energy. electric modulus representation employed determine relaxation time quantitatively numerically. No found.
