Topological characterization of nanoporous gold during coarsening
Previous studies of nanoporous gold have found that, during the coarsening process, the genus per characteristic volume of nanoporous gold has remained constant. Using a rolling-ball type algorithm, in which a test probe rolls over the surface to identify atoms, several test structures and a …

Investigating the origin of localized plastic deformation in nanoporous gold by in situ electron microscopy and automatic structure quantification
… many useful properties when it is formed into a nanoporous structure, but it also becomes macroscopically brittle due to flow localization and may therefore be unreliable for many applications. The goal of this work was to establish processing/structure/property relationships of nanoporous gold, …

Synthesis and applications of silver and palladium nano metal foams
Nanoporous metal foams (NMFs), a relatively new class of materials with low-density, high surface area and conductivity, have been studied recently in nano science. These materials can be engineered to benefit many fields and promise to enable new technologies in areas such as hydrogen storage, …

STRUCTURAL AND OPTICAL PROPERTIES IN POROUS NANOSTRUCTURED SEMICONDUCTORS
… Voltage quenching of PL from p-type PS with a nanoporous structure has been studied using samples with different types of solid contacts and the effect of these on quenching examined. Voltage quenching has allowed us to distinguish quenching mechanisms with two distinct induced non-radiative …

Protonic All-Solid-State Electrochemical Device as an Artificial Synapse for CMOS-Compatible Neuromorphic Computing
… electrochemical artificial synapse employing the nanoporous gadolinium (Gd)-doped ceria (Gd:CeO₂) as an inorganic solid proton electrolyte. The Gd:CeO₂ was carefully chosen based on the consideration of its high proton conductance, doping effect, and fabrication compatibility with current …

Solid-state Polymer Nanofoams
… temperature and foaming temperature) to cellular structures. Nanofoams are created with a smallest cell size around 20 nm and maximum cell nucleation density on the order of 1e15 cells per cubic centimeter. Also, a critical carbon dioxide concentration is observed, above which the cell nucleation …

Characterization, Processing, and Synthesis of Extreme-Performance Continuous Carbon Nanotube Network Composites
… (CNT) networks are an emerging, hierarchically-structured, and commercially available nanomaterial built from countless CNT nanocrystals. These macroscopic yarn materials promise to bridge the gap between microscopic CNT fibers – which are well-known for their superlative material properties – …

Interrogating electrocatalytic mechanisms and developing nano-porous catalysts for energy conversion reactions: I. Oxygen evolution reaction, and II. Carbon dioxide reduction reaction
… are varied to exhibit wires, dots, or amorphous structures. Among these Cu films, the CuDAT-wire samples exhibit the best CO2 reduction activity with a Faradaic efficiency (FE) of the C2H4 product formation reaching 41% at -0.47 V vs. RHE, a FE for C2H5OH formation reaching 22% at -0.55 V vs. …

Characterization of Nanoporous Polyvinylidene Fluoride (PVDF) Sensors under Tensile Loading
… Fluoride (PVDF) sensor with integrating nanoporous structures was developed and fabricated. Several sets of samples with different porosities from 0% to 42.0% were made. The porosity effect on the sensor samples was studied under tensile loading, and the piezoelectric coefficient d31 was …
