Graphene Outperforms Metal Junctions for 2D Semiconductors
Researchers found that graphene performs ten times better than metal in transmitting a photoinduced current across interfaces with 2D semiconductors. Nanoscale-resolution band-structure measurements provided a deeper understanding of charge transport in these systems and will help in engineering more efficient contacts. Read more »
To Design Truly Compostable Plastic, Scientists Take Cues From Nature
Researchers have designed an enzyme-activated compostable plastic that could diminish microplastics pollution and holds great promise for plastics upcycling. The material can be broken down to its building blocks—small individual molecules called monomers—and then reformed into a new compostable plastic product. Read more »
The Spintronics Technology Revolution Could Be Just a Hopfion Away
Scientists have long treated skyrmions as merely 2D objects. Recent studies, however, have suggested that 2D skyrmions could actually be the genesis of a 3D spin pattern called hopfions. Now, a team of researchers has reported the first demonstration and observation of 3D hopfions emerging from skyrmions at the nanoscale in a magnetic system. Read more »
Hybridized Radial and Edge Coupled 3D Plasmon Modes in Self-Assembled Graphene Nanocylinders
The researchers report hybridized 3D plasmon modes stemming from 3D graphene nanostructures, resulting in non-surface-limited (volumetric) field enhancements and a four orders of magnitude stronger field at the openings of cylinders than in rectangular 2D graphene ribbons. Read more »
Designing Selective Membranes for Batteries Using a Drug Discovery Toolbox
Researchers designed a polymer membrane with molecular cages built into its pores that hold positively charged ions from a lithium salt. These “solvation cages” increased lithium-ion flow by an order of magnitude and could allow high-voltage battery cells to operate at higher power and more efficiently, important for both electric vehicles and aircraft.

Chiral Spin Textures in Amorphous Iron–Germanium Thick Films
Robert Streubel and co‐workers report the formation of topological magnetization vector fields in disordered materials with local inversion symmetry breaking, harnessing high‐resolution Lorentz microscopy, quantitative x‐ray microspectroscopy, and coherent scattering. The image shows the reconstructed in‐plane magnetic induction of closely packed Bloch skyrmions embedded into helical spins. Read more »
Actor in a Supporting Role: Substrate Effects on 2D Layers
ALS studies highlighted interactions that can occur between technologically intriguing 2D materials and the substrates that physically support them. The results provide important insights into the issue of non-negligible interlayer coupling and demonstrate the potential for tuning single-layer properties through substrate engineering. Read more »
Identifying Ionic and Electronic Charge Transfer at Oxide Heterointerfaces
Researchers identified how ion and electron transfer naturally balance at the LaAlO3/SrTiO3 oxide heterointerface, affecting the band alignment and magnetic signature of the interface. The results show that Sr ions are more mobile at the interface than in the bulk, implicating a high importance of ionic charge transfer in oxide heterostructures. Read more »
