Seeded Growth Synthesis of Gold Nanotriangles: Size Control, SAXS Analysis, and SERS Performance

Kuttner, Christian; Mayer, Martin; Dulle, Martin; Moscoso, Ana; López-Romero, Juan Manuel; Förster, Stephan; Fery, Andreas; Pérez-Juste, Jorge; Contreras-Cáceres, Rafael

We studied the controlled growth of triangular prismatic Au nanoparticles with different beveled sides for surface-enhanced Raman spectroscopy (SERS) applications. First, in a seedless synthesis using 3-butenoic acid (3BA) and benzyldimethylammonium chloride (BDAC), gold nanotriangles (AuNTs) were synthesized in a mixture with gold nanooctahedra (AuNOCs) and separated by depletion-induced…

Reverse micelles as nanocarriers of nisin against foodborne pathogens

Chatzidaki, Maria D.; Papadimitriou, Konstantinos; Alexandraki, Voula; Balkiza, Fani; Georgalaki, Marina; Papadimitriou, Vassiliki; Tsakalidou, Effie; Xenakis, Aristotelis

Reverse micelles (RMs) as nanocarriers of nisin were optimized for the highest water and bacteriocin content. RMs formulated with either refined olive oil or sunflower oil, distilled monoglycerides, ethanol, and water were effectively designed. Structural characterization of the RMs was assessed using Electron Paramagnetic Resonance Spectroscopy and Small Angle X-ray…

Langmuir – Blodgett monolayers of SBA-15 particles with different morphologies

Znamenskaya Falk, Yana; Schmitt, Julien; Alfredsson, Viveka

This study presents an optimized protocol for the deposition of mesoporous SBA-15 particles with platelet-like and rod-like morphologies on different types of supporting substrates using Langmuir-Blodgett methodology, resulting in the formation of monolayers with porosity orientation controlled by the type, i. e. the morphology, of particles used over large areas.…

On the properties of poly(isoprene-b-ferrocenylmethyl methacrylate) block copolymers

Chernyy, Sergey; Kirkensgaard, Jacob Judas Kain; Bakke, Anders; Mortensen, Kell; Almdal, Kristoffer

By combining poly(1,4-isoprene) (PI) with poly(ferrocenylmethyl methacrylate) (PFMMA) in a diblock copolymer structure by means of anionic polymerization we obtained narrowly dispersed PI-b-PFMMA copolymers with molecular weight ranging from 13000 to 62000 g/mol. The products were stable up to 228 °C, according to thermal gravimetry, which allowed us to further investigate their…

Flocculated Laponite-PEG/PEO Dispersions with Multivalent Salt: A SAXS, Cryo-TEM, and Computer Simulation Study

Thuresson, Axel; Segad, M.; Plivelic, Tomás S.; Skepö, Marie

The aim of this study is to scrutinize the mechanism behind aggregation, i.e., tactoid formation of nanostructures with the shape of a platelet. For that purpose, the clay minerals Laponite and montmorillonite have been used as model systems. More specifically, we are interested in the role of: the platelet size,…

Electrostatic Effect on the Solution Structure and Dynamics of PEDOT:PSS

Leaf, Michael A.; Muthukumar, Murugappan

Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) is a material consisting of two oppositely charged polymers and is available as aqueous dispersions. Various annealing and doping methods dramatically enhance PEDOT:PSS conductivity, rendering it competitive with inorganic conductors like indium tin oxide. Yet a comprehensive understanding of PEDOT:PSS conductivity…
