NANOMATERIALS
Engineering graphene-based quantum circuits with atomic precision
Researchers synthesized a new nanoporous graphene structure by connecting ultranarrow graphene nanoribbons using flexible bridges made of phenylene moieties. By modifying the architecture and angle of these bridges, they can control the quantum connectivity between the nanoribbon channels and, ultimately, fine-tune the electronic properties.
Symmetric graphene quantum dots for future qubits
Researchers at Forschungszentrum Jülich and RWTH Aachen University used bilayer graphene to create a double quantum dot: two opposing quantum dots whose spin properties mirror each other almost perfectly. The symmetry and strong selection rules are attractive not only for operating qubits but also for realizing single-particle THz detectors.

New concept intends to extend the life of lithium-air batteries
A newly initiated collaborative research project is exploring a new concept to extend the life of lithium-air batteries by creating a membrane that divides the positive electrode from the negative electrode, allowing alternative electrolytes to be used on either side.
Additive to efficiently improve the efficiency and stability of perovskite solar cells
Researchers from City University of Hong Kong developed an innovative multifunctional and nonvolatile additive (4-guanidinobenzoic acid hydrochloride) that can improve the efficiency and stability of perovskite solar cells by modulating perovskite film growth.
