New Dual-Beam Microscope Installed at the Center for Functional Nanomaterials

This latest-generation tool, which combines a scanning electron microscope and focused-ion beam, has advanced capabilities for preparing and analyzing nanomaterial samples.

Laser-Driven “Chirp” Powers High-Resolution Materials Imaging

Scientists use beams of electrons to study materials’ properties. Shorter beams produce higher-resolution views. To make shorter beams, the electrons at the tail of the beam need to catch up to the head of the beam. This is accomplished by giving the electrons at the tail extra energy, a so-called “energy chirp.” Scientists have now used a terahertz laser pulse to create this energy chirp.

E-Beam Atomic-scale 3-D “Sculpting” Could Enable New Quantum Nanodevices

By varying the energy and dose of tightly-focused electron beams, researchers have demonstrated the ability to both etch away and deposit high-resolution nanoscale patterns on two-dimensional layers of graphene oxide. The 3D additive/subtractive “sculpting” can be done without changing the chemistry of the electron beam deposition chamber, providing the foundation for building a new generation of nanoscale structures.

‘Blinking” Crystals May Convert CO2 into Fuels

Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.
