Quantum Conductance in Memristive Devices: Fundamentals, Developments, and Applications (Advanced Materials 34/2022)

In article number 2201248, Gianluca Milano, Ilia Valov, and co-workers review the state-of-the-art of quantum conductance effects in memristive devices. Besides analyzing fundamental physicochemical phenomena and electronic ballistic transport in nanofilaments, recent developments in experimental observation of quantum effects in memristive devices and related challenges are discussed. Representing suitable platforms for investigating quantum phenomena at room temperature, future perspectives of memristive devices in quantum and neuromorphic systems are envisioned.

Hyperbolic Metamaterials via Hierarchical Block Copolymer Nanostructures (Advanced Optical Materials 7/2021)

The dewetting of lamellar phase block copolymer films over topographically defined substrates generates hierarchically aligned hyperbolic metamaterials (HMM) with in‐plane optical axis. Strong reduction in the fluorescence lifetime was observed in nanodiamonds coupled to the Au/air HMM. The analyzed system exhibits hyperbolic behavior in a broad wavelength range in the visible spectrum. For further details, see article number 2001933 by Federico Ferrarese Lupi and co‐workers.

Brain‐Inspired Structural Plasticity through Reweighting and Rewiring in Multi‐Terminal Self‐Organizing Memristive Nanowire Networks

In article number 2000096, Daniele Ielmini, Ilia Valov, Carlo Ricciardi, and co‐workers report a brain‐inspired complex system based on self‐organizing memristive nanowire networks with functional connectivity that exhibit structural plasticity including rewiring and reweighting effects. These neuromorphic systems allow the realization of neural networks with heterosynaptic plasticity able to learn and adapt when subjected to external stimuli, emulating the experience‐dependent plasticity of the nervous system.

Memristive Devices for Quantum Metrology

In the light of the revision of the International System of Units (SI), in article number 2000009 Gianluca Milano and co‐workers discuss on the possibility of using memristive devices for quantum metrology. Exhibiting quantized conductance phenomena in air at room temperature, memristive devices can be exploited for the realization of a resistance standard implementable on‐chip for self‐calibrating systems with zero‐chain traceability.

Tailored and Guided Dewetting of Block Copolymer/Homopolymer Blends

The morphological instability of lamellae forming PS-b-PMMA block copolymer blended with low molecular weight polystyrene and poly(methy lmethacrylate) homopolymers results in dewetting of relatively thick films and the formation of micrometric size droplets consisting of highly ordered and defect-free perpendicular lamellae monodomains.
