Researchers at the Hong Kong University of Science and Technology (HKUST) School of Engineering have cracked a major challenge in display technology by inventing the world’s brightest and most energy efficient quantum rod LEDs (QRLEDs). These next-generation QRLEDs feature optimized deep green emission at the top of the colour triangle, enabling displays with unprecedented colour purity and a maximized colour gamut. Boasting a longer lifespan and triple the brightness of previous models, these cutting-edge light sources deliver energy-efficient, ultra-vivid visuals for smartphones, televisions, and AR/VR devices while further enhancing colour performance.

The relentless down-scaling of electronics grands the modern integrated circuits (ICs) with the high speed, low power dissipation and low cost, fulfilling diverse demands of modern life. Whereas, with the semiconductor industry entering into sub-10 nm technology nodes, degrading device performance and increasing power consumption give rise to insurmountable roadblocks confronted by modern ICs that need to be conquered to sustain the Moore law’s life. Bulk semiconductors like prevalent Si are plagued by seriously degraded carrier mobility as thickness thinning down to sub-5 nm, which is imperative to maintain sufficient gate electrostatic controllability to combat the increasingly degraded short channel effects. Nowadays, the emergence of two-dimensional (2D) materials opens up new gateway to eschew the hurdles laid in front of the scaling trend of modern IC, mainly ascribed to their ultimately atomic thickness, capability to maintain carrier mobility with thickness thinning down, dangling-bonds free surface, wide bandgaps tunability and feasibility to constitute diverse heterostructures. Blossoming breakthroughs in discrete electronic device, such as contact engineering, dielectric integration and vigorous channel-length scaling, or large circuits arrays, as boosted yields, improved variations and full-functioned processor fabrication, based on 2D materials have been achieved nowadays, facilitating 2D materials to step under the spotlight of IC industry to be treated as the most potential future successor or complementary counterpart of incumbent Si to further sustain the down-scaling of modern IC.

Surface-engineered LNPs, propelled by clinical successes like patisiran and mRNA vaccines, enable targeted nucleic acid delivery via ligands (antibodies, peptides) and conjugation chemistries (click reactions). These LNPs target organs (liver, lungs) and cells (immune, brain), advancing gene therapy and vaccines. Key challenges—batch reproducibility, ligand stability, scalable production—must be resolved to accelerate clinical translation and expand applications to protein/small-molecule delivery.
