The quantum battery (QB) has been proposed as an alternative to the electrochemical energy storage devices we know so well.

CHICAGO, June 26, 2025 /PRNewswire/ -- The global microgrid market is projected to hit the market valuation of US$ 191.01 billion by 2033 from nearly US$ 40.9 billion in 2024 at a CAGR of 19.28% ...

In order to determine the spectral characteristics of the material (for example, the chemical composition at each point), we apply silver, gold or platinum to the probe in such a way that a single ...

Why it matters: 1. Quantum dots, often called artificial atoms, can mimic atomic orbitals but have not yet been used to simulate orbital hybridization, a crucial process in real atoms. 2. While ...

Abstract: We study the optical response of multilayer graphene quantum dots at THz frequencies. We fabricate 73 nm diameter graphene quantum dots in an array of ~1mm 2 size. We demonstrate optical ...

Jul 26, 2024 Graphene-quantum dot hybrid enables compact multispectral light detection (Nanowerk Spotlight) Light detection across multiple wavelengths underpins numerous technological applications, ...

Graphene vs. metallic quantum dots: the confined states. (a–c) The EPWE calculated electronic structure for (a) the smallest graphene quantum dot (GQD) and (b, c) for the same size 2D metallic quantum ...

Graphene is coupled with silicon quantum dots (Si QDs) on the top of bulk Si to form a hybrid photodetector. SiQDs cause the built-in potential of the graphene/Si Schottky junction to increase. Si QDs ...

Graphene quantum dots (GQDs) are a part of the carbon quantum dots family.1 These zero-dimensional carbon nanomaterials possess many superior properties, such as low biological toxicity, nanoscale ...

While valley states in bilayer graphene were known before, their suitability as practical qubits remained unclear until now. Garreis, Tong, and co-workers considered a double quantum dot – that is, ...

In graphene as well as in other carbon-based materials, spin-orbit coupling and hyperfine interaction are both weak: this makes graphene quantum dots especially appealing for spin qubits.
