Safety and Process Intensification of Catalytic Reduction of 4-Nitophenol Using Sodium Borohydride in Flow Microreactor System

Catalysts
In this work, a novel approach for the catalytic reduction of 4-nitrophenol to 4-aminophenol using sodium borohydride is proposed. It was shown that a continuous-flow microreactor system is an optimal tool for PdNP synthesis with dimensions of 3.0 ± 0.5 nm, as well as the performance of catalytic tests with high process efficiency, while keeping a high

The cellular interactions of PEGylated gold nanoparticles : effect of PEGylation on cellular uptake and cytotoxicity [PDF]

, 2014
Poly(ethylene glycol) (PEG) is frequently used to coat various medical nanoparticles (NPs). As PEG is known to minimize NP interactions with biological specimens, the question remains whether PEGylated NPs are intrinsically less toxic or whether this is ...

Integrating agro‐residue valorization and clean hydrogen production: coconut fiber‐based catalysts for NaBH4 hydrolysis

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract A novel phosphoric acid‐treated green coconut fiber (GCF‐C) was developed as a catalyst for hydrogen production from the hydrolysis of sodium borohydride (NaBH4). Characterization techniques confirmed structural modifications, including X‐ray diffraction, scanning electron microscopy, X‐ray fluorescence, Fourier transform infrared, and ...

Study of aluminoborane compound AlB_4H_(11) for hydrogen storage [PDF]

, 2009
Aluminoborane compounds AlB_4H_(11), AlB_5H_(12), and AlB_6H_(13) were reported by Himpsl and Bond in 1981, but they have eluded the attention of the worldwide hydrogen storage research community for more than a quarter of a century.

Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]

, 2017
The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could
