Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Two Coexisting Pathways to Volatility in Valence‐Change Memory Devices

open access: yesAdvanced Functional Materials, EarlyView.
Volatile VCM‐type memristive devices exhibit current relaxation after resistive switching, but their microscopic origin remains debated. Using pulsed measurements and a new Tunnel‐DLTS approach on Pt/SrTiO3/Nb:SrTiO3 devices, we show that post‐SET volatility is predominantly ionic, while electronic contributions—arising from quasi‐Fermi‐level ...

Unusual Temperature‐Enhanced Bulk Photovoltaic Effect Beyond the Centrosymmetric Phase in CuCrP2S6 van der Waals Crystals

open access: yesAdvanced Functional Materials, EarlyView.
Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

open access: yesAdvanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Designing whole landscapes

Landscape Research, 2001
A whole-landscape approach is critical to ensuring conservation and enhancement of biodiversity in farmed landscapes. Although existing agri-environmental schemes are constrained by property boundaries and voluntary take up, the potential for adopting a whole-landscape approach to planned countryside management is currently favoured by a number of ...

The Changing Design Landscape

IEEE Design & Test of Computers, 2008
This sidebar explains that the burden of enabling Moore's law to continue is gradually moving from the process technologists to the designers. As technology moves from 65 nm to 22 nm, the number of transistors on a big chip will go from approximately 2 billion to 15 billion.

Landscape : Expressive Landscapes, Perception and Design

2020
In the light of the psychological research on expressive qualities, this chapter deals with the landscape in terms of design. In particular, the phenomenological-experimental approach excludes physicalist and subjectivist prejudices in the study of immediate experience and allows the experimental investigation of tertiary-expressive qualities.
