Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials
Advanced Science, EarlyView.ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

XOR‐Logic Phase Coding Programmable Metasurface for Low Power‐Consumption Systems
Advanced Science, EarlyView.By leveraging XOR logic, the biasing‐network complexity of 2D programmable metasurfaces is reduced from m×n to m+n through efficient row‐column control. This enables versatile functions including beam deflection and beamforming, facilitating applications in wireless communications and beyond.

Advanced Science, EarlyView.A (111)‐oriented nanotwinned copper substrate stabilizes the deposited nanograined copper and prevents self‐annealing by restricting grain boundary motion at the interface and promoting the formation of stacking faults within the nanograined copper. Its preserved nanostructure maintains bonding capability even after 30 days of storage, resulting in ...

Spot-Weld Fatigue Optimization
, 2018 The purpose of this thesis project is to develop a methodology that can be used to minimize the number of spot-welds in a mechanical structure, this is done in a reliable manner via optimization methods. The optimization considers fatigue life in spot-welds and also stiffness and eigenfrequency values.

Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis
Advanced Science, EarlyView.Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).

Characterization of the Plasma Shape of the TIG Welding Arc [PDF]
, 2006 Tungsten electrodes were prepared to analyse the plasma geometry at TIG welding. The investigated electrodes were La02, Th02 alloyed. Tip flatted electrodes were grinded as well. The shape of plasma were analysed for 36 different electrodes.
