A Cage Made of Proteins, Designed With Help From the Advanced Light Source

With help from Berkeley Lab’s Advanced Light Source, scientists from UCLA recently designed a cage made of proteins. The nano-sized cage could lead to new biomaterials and new ways to deliver drugs inside cells. It boasts a record breaking 225-angstrom outside diameter, the largest to date for a designed protein assembly. It also has a 130-angstrom-diameter

Outsmarting Thermodynamics in Self-assembly of Nanostructures

Berkeley Lab researchers have achieved symmetry-breaking in a bulk metamaterial solution for the first time, a critical step game toward achieving new and exciting properties in metamaterials.

Nanotubes that Insert Themselves into Cell Membranes

Berkeley Lab researchers have helped show that short carbon nanotubes can make excellent artificial pores within cell membranes. Moreover, these nanotubes, which are far more rugged than their biological counterparts, can self-insert into a cell membrane or other lipid bilayers.

Lord of the Microrings

Berkeley Lab researchers report a significant breakthrough in laser technology with the development of a unique microring laser cavity that can produce single-mode lasing on demand. This advance holds ramifications for a wide range of optoelectronic applications including metrology and interferometry, data storage and communications, and high-resolution spectroscopy.

Berkeley Lab researchers believe they have uncovered the secret behind the unusual optoelectronic properties of single atomic layers of TMDC materials, the two-dimensional semiconductors that hold great promise for nanoelectronic and photonic applications.

Peptoid Nanosheets at the Oil/Water Interface

Researchers at Berkeley Lab’s Molecular Foundry have developed peptoid nanosheets that form at the interface between oil and water, opening the door to increased structural complexity and chemical functionality for a broad range of applications.

Competition for Graphene

Berkeley Lab reports the first experimental observation of ultrafast charge transfer in photo-excited MX2 materials, the graphene-like two-dimensional semiconductors. Charge transfer time clocked in at under 50 femtoseconds, comparable to the fastest times recorded for organic photovoltaics.

Shaping the Future of Nanocrystals

Berkeley Lab researchers have recorded the first direct observations of how facets form and develop on platinum nanocubes in solution, pointing the way towards more sophisticated and effective nanocrystal design and revealing that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

Bottling Up Sound Waves

Berkeley Lab researchers have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories. These self-bending bottle beams hold promise for ultrasonic imaging and therapy, and for acoustic cloaking, levitation and particle manipulation.
