Kinetic analysis of silver nanowire synthesis: polyol batch and continuous millifluidic methods.

This study investigates the variation in rate constants for nucleation and growth of silver nanowires (AgNWs) synthesized using the polyol method in batch and millifluidic flow reactors (MFRs). In a particular reactor, silver ion concentration at any time is quantified by the method of El-Ghamry and the non-linear two-step Finke-Watzky model is used to determine the rate constants for nucleation () and growth (). The results indicate that and for the MFRs are approximately four and two times larger, respectively, than the batch reactor rate constants.

Electroless Deposition of Noble Metals on Rod-Shape Plant Viruses in Various Aqueous Metal Precursor Solutions.

The challenge of synthesizing noble metal nanostructures sustainably has encouraged researchers to explore biological routes for nanostructure production, such as biotemplating. Plant viruses with rod-shape morphology, such as tobacco mosaic virus (TMV) and barley stripe mosaic virus (BSMV), offer promising biotemplates to produce metal nanorods. TMV and BSMV can be incubated in aqueous metal precursor solutions to mineralize metals on the coat proteins (CPs) of the viruses.

Sustainable, Green, and Continuous Synthesis of Fivefold Palladium Nanorods Using l-Ascorbic Acid in a Segmented Millifluidic Flow Reactor.

Pd nanorods (PdNRs) have recently come to attention due to their wide array of applications. The green synthesis of PdNR with a relatively high yield and high aspect ratio is challenging. A continuous millifluidic flow reactor (CMFR) has been explored to precisely control mass and heat transfer as well as mixing in the PdNR synthesis processes.

A review on the green and sustainable synthesis of silver nanoparticles and one-dimensional silver nanostructures.

The significance of silver nanostructures has been growing considerably, thanks to their ubiquitous presence in numerous applications, including but not limited to renewable energy, electronics, biosensors, wastewater treatment, medicine, and clinical equipment. The properties of silver nanostructures, such as size, size distribution, and morphology, are strongly dependent on synthesis process conditions such as the process type, equipment type, reagent type, precursor concentration, temperature, process duration, and pH. Physical and chemical methods have been among the most common methods to synthesize silver nanostructures; however, they possess substantial disadvantages and short-comings, especially compared to green synthesis methods.

A rapid millifluidic synthesis of tunable polymer-protein nanoparticles.

Polymeric nanoparticles have drawn recent attention for their ability to enhance the efficacy of therapeutic proteins through reduced immunogenicity and extended circulation time. Though effective, most nanoparticle drug delivery systems are currently produced in batch processes that are limited in control parameters and scalability. To address these deficiencies, a millifluidic process was developed to encapsulate bovine serum albumin in poly(L-lysine)-grafted-poly(ethylene glycol) through an electrostatic self-assembly mechanism.
