The release of strain energy is a fundamental driving force for organic reactions. However, strain release alone is an insufficient predictor of reactivity, as seen in the equivalent strain energies but disparate reactivity of cyclopropane and cyclobutane. Here we show that bond delocalisation is a key factor that…

Embedding mechanophores into polymer matrices to activate mechanochemical reactions has been extensively employed to realize diverse functional applications. Spiropyran (SP) is a widely used mechanophore that undergoes force-induced isomerization into its activated merocyanine (MC) form, accompanied by a color change.…

Hydrogen embrittlement severely degrades mechanical properties of austenitic stainless steels (γ-SS), yet the bulk deformation microstructures responsible for this phenomenon have not been directly observed. While the internal microstructure is essential to define metal plasticity, deformation, and fracture, no…

Materials with special geometrically designed microstructures, referred to as metamaterials, have gained significant attention in the world due to their unique properties of toughness and failureresistance. The ability to simply alter the internal geometry of almost any material to exponentially increase strength is…

Stretchable electronics require sophisticated fabrication strategies to achieve both high electrical performance and mechanical compliance. While various approaches exist, from geometric designs to composite materials, most face challenges in balancing fabrication complexity with device performance. Here, we present a…

Shaping supramolecular hydrogels formed using low molecular weight gelators (LMWGs) into architecturally complex and multifunctional materials is a significant challenge. Here, we introduce a strategy to mechanically twist multiple 1D supramolecular gel filaments (gel noodles) into robust, multifunctional, and…

This study presents the use of laser-driven microbubbles for micro-patterning Ti3C2TX MXenes on flexible polyethylene terephthalate films, yielding conductive micropatterns without the need for pre- or post-processing. Characterization of the electrical properties under varying strain conditions revealed distinct…

Understanding the coupling between mechanical integrity and ionic conductivity in solid electrolytes is central to the development of high-performance solid-state lithium batteries. In this work, a machine-learning interatomic potential (MLIP) was developed and iteratively refined to investigate the structural…

Nacre-like aluminas are bio-inspired, ceramic-based composites that display high toughness and strength. Their toughness arises from their brick-and-mortar microstructure. We must understand the role of several microstructural features over their mechanical properties. Techniques that allow microstructural imaging…

Phosphorene, a puckered 2D allotrope of phosphorus, has shown high carrier mobility and high surface-area to volume ratio allowing for many multifunctional applications. Because of this, phosphorene has seen much interest from industries such as electronics, photonics, biomedics, linear polarizers, and plasmonics. One…

A glassy polymer containing a supramolecular mechanophore capable of responding to mechanical deformation is reported. The supramolecular mechanophore LOOP, which comprises two perylene diimide (PDI) connected by a flexible linker, was functionalized with an atom transfer radical polymerization initiator, allowing…

In the framework of density functional theory (DFT), we investigate the structural deformation, and mechanical behavior of the Janus CrSSe, which has out-of-plane structural asymmetry, with conventional transition metal dichalcogenides (TMDs) CrS2 and CrSe2 . The Janus CrSSe could be a potential candidate for…

This work demonstrates the fabrication, mechano-electric, and electrochemical characterisation of a sustainable, fully 3D-printed electrochemical cell (3DPEC) for electroanalytical applications in static and flow conditions. The two-electrode cell comprises carbon black (CB)-filled polylactic acid (PLA) electrodes…
