Strategies for Minimizing Reflection by Electrocatalysts Integrated on Silicon Microwire Array Photocathodes

Written by Gargi Joshi

The semiconductor industry has an ever-growing demand and new innovations are desired as an improvement over the existing materials. In this regard, Paul Kempler presented a poster about photoelectrodes and how a high aspect ratio along with microstructured patterns can provide integration of reflective and opaque electrocatalysts with semiconducting light absorbers. This even helps in deflecting the loss due to the maximum current density. In this work, wire and cone arrays of platinum in micrometer scale were electrochemically deposited on a p-type silicon substrate to fabricate photocathodes. The photocurrent densities obtained were significantly higher than that of the conventional devices. The thickness of the deposited layers was also varied to optimize the results and reduce overpotentials of hydrogen production.


Symposium CP02: Design and In Situ TEM Characterization of Self-Assembling Colloidal Nanosystems

Solution Phase Behavior of Polymer-Grafted Nanoparticles—Improving Assembly and Processability

Written by Gargi Joshi

Self-assembled polymers have found scope in a number of applications such as optics, electronics, photonics, and multifunctional coatings. Grafting of nanoparticles (PGN) with these polymer chains, provide with them additional features depending upon the grafting density and chain length acquired. To further manipulate these properties, an understanding of the solution phase behavior of the PGN is essential. In her poster presentation, Sarah Izor talks about polystyrene-grafted gold nanoparticles and the analysis of the upper critical solution coexistence curve using techniques such as UV-Vis spectroscopy, dynamic light scattering and small angle x-ray scattering. Increasing the molecular weight of the grafted polymer led to a shift in temperature values. Izor believes that such critical insights ultimately guide the rapid self-assembly of PGN monolayers on solid substrates.

Growth of Silver Dendritic Nanostructures Decorated with Gold Nanospheres and their Application as Sers Substrate

Written by Gargi Joshi

This presentation won one out of the three Poster awards during the XXVII International Materials Research Congress held last year. Manuel Ceballos talked about the surface-enhanced Raman spectroscopy (SERS) as a very powerful tool capable of providing lower limits of elemental detection regardless of the presence of interferences, enabling a range of materials to be analyzed. Noble metals like gold (Au) are used as coatings due to their inherent optical property of surface plasmon resonance. The work studied electrodeposited silver on preferably aluminum sheet as a substrate using silver nitrate solution. Next, the silver nanostructures were coated with gold nanospheres using the electrophoretic deposition. Detection of an ultralow value of 1 ppb analyte concentration demonstrated the advantage of this technique along with it being quick, affordable, and - most importantly - reproducible.

The other poster presenters were Kevin Fitzwell of the University of California, Los Angeles on Design of Galfenol/permalloy Nanolaminates for Incorporation Into a Strain-mediated Nanoscale Antenna and Arlet Ariadne Rodríguez of Instituto Politécnico Nacional – Ipn on Effect of Modification of the Surface of Mesoporous Silica in the Adsorption-desorption of Griseofulvine
