Transparent non-wetting surfaces with mechanical robustness are critical for applications such as contamination prevention, (anti-)condensation, anti-icing, anti-biofouling, etc. The surface treatments in these often use hazardous per- and polyfluoroalkyl substances (PFAS), which bio-persistent or have compromised durability due to weak polymer/particle interfacial interactions. Hence, developing new approaches synthesise non-fluorinated liquid-repellent coatings attributes scalable...

Cavitation erosion remains the primary cause of material degradation in fluid machinery components operating at high speed. Micro-jets/shock waves caused by implosion bubbles on surface results significant loss and premature failure components. The presence corrosive medium further exuberates this effect, causing rapid degradation. Here, we demonstrate a novel pathway to control cavitation erosion-corrosion tailoring properties using submerged friction stir processing (FSP), severe plastic...

Diagnosing acute rejection of kidney transplant remains challenging as standard practice relies on monitoring serum creatinine levels and performing biopsies. The former lacks sensitivity, while the latter is invasive. Monitoring Chemokine IP-10 (or CXCL10) in patient samples has shown promising results addressing these bottlenecks but measured with expensive time-consuming protocols such enzyme-linked immunosorbent assay (ELISA). This does not allow for an individualized approach. present...

Abstract Slippery lubricant infused porous surfaces (SLIPS) have the potential to address daunting challenges such as undesirable surface fouling/biofouling, icing, etc. However, depletion of lubricants hampers their practical utility. As a solution, here rational strategy is introduced that operates synergistically in three parts. First, ultra‐high capillary pressure exploited from reticular structure metal‐organic frameworks (MOFs) with sub‐nanometer pores. Second, need for geometric...
