2020 Highlights

The image shows deformed nanoboxes. Crushing Nanoboxes

The ability to simultaneously control yield strength and hardening by changing sample dimensions – while keeping the same structural geometry – has been demonstrated using in-situ SEM and TEM compression of gold-silver nanoboxes and molecular dynamics simulations.

The image shows a schematic of hole localization at Br atoms (green balls) that promotes light emission for bright LEDs. Molecular Engineering Makes Bright LEDs

By incorporating bulky organic molecules, with atoms arranged in a ring, scientists have produced 2D layered perovskite LEDs with a seven-fold increase in brightness compared to perovskite LEDs layered with organic molecules in a linear chain.

Artistic rendering showing that uric acid crystals with doped (i.e., dyed) sectors of increasing concentrations exhibit a trend of softening followed by strengthening. Tuning Mechanical Properties of Molecular Crystals

For the first time, scientists have measured and quantified mechanical property changes in molecular materials after introducing engineered defects into uric acid crystals. They found increased softening at low dopant concentrations and increased material strength at high concentrations.

Researchers used in-situ synchrotron high-pressure WAXS and TEM to investigate the high-pressure behaviors as a function of particle shapes: CdS nanospheres (top), short CdS nanorods (middle), long CdSe/CdS nanorods. High-Pressure Properties of Nanocrystals Sensitive to Particle Shape

Using wide-angle X-ray scattering (WAXS) and transmission electron microscopy (TEM), scientists have shown that the shape of semiconductor nanocrystals plays an important role in determining their high-pressure properties, specifically for phase transitions.

Image shows TEM images of plasmonic catalyst nanoparticles composed of Au and Au/Ni. Plasmonic Nanoparticles Could Hold the Key to Speeding Up Catalytic Reactions

Using ultrafast optical spectroscopy to compare nanoparticles of gold, gold/nickel, and gold/platinum, CINT scientists have shown that the optical properties of these plasmonic nanoparticles are affected by their composition.

The image shows a schematic of one-way focusing. Nonreciprocity Enables Next-Generation Communication Technology

For the first time, scientists have demonstrated extreme nonreciprocity in microwave reflections, allowing one-way steering and focusing of signals.

The SEM images show the 100 nm-thick ultrafine -grained gold thin films used to test the technique. Governing Mechanisms of Plastic Deformation Revealed with In-Situ TEM

For the first time, scientists have measured true activation volume using in-situ TEM observations of plastic deformation in ultrafine-grained gold under tension.

The image shows photoluminescence lifetime and intensity from nanoparticle assemblies spatially mapped on the nanoscale. Spatio-Temporal Optical Imaging at the Nanoscale

Photoluminescence lifetime and intensity from nanoparticle assemblies was spatially mapped on the nanoscale using a newly developed super-resolution imaging system.

The image shows how 3D mesh-like copper is functionalized with partially reduced graphene oxide. Frustrating Harmful Dendrite Formation in Potassium Ion Batteries

A novel technology has been developed for potassium ion batteries which reduces dendrite formation, a key factor in premature battery failure.

The image shows a snapshot from a molecular simulation of ring polymers undergoing uniaxial elongation flow. Elongated Ring Polymers Get Tied Up In Knots

Scientists have discovered a new flow-driven linking process in ring polymers that explains their anomalous viscosity.

The image shows in-situ laser-heating and compression TEM images of zirconium-oxide pillars and the associated stress-strain response at elevated temperatures. Turning Brittle Ceramic into Silly Putty in a TEM

To explore materials response to extreme environments, a new approach has been developed at CINT combining laser heating and quantitative mechanical testing during in-situ Transmission Electron Microscopy (TEM).
