Therapeutic-scale CAR-NK microrobots with programmable swarm navigation for targeted solid tumor therapy

An urgent requirement in chimeric antigen receptor (CAR) immune cell therapy [e.g., CAR–natural killer (NK) cells] for solid tumors is to engineer the cells for precise tumor targeting. Meanwhile, medical microrobots can be navigated toward specific target sites using external ma...

Exploring hydrogen production from plastic waste for urban transportation in Hong Kong and its environmental impact mitigation: integrating dynamic material flow analysis and life cycle assessment

Plastic waste to hydrogen technology offers a sustainable clean energy pathway while reducing landfill and incineration burdens. However, its feasibility as a feedstock for urban mobility decarbonization at the city scale remains largely unexplored. Hong Kong, as a densely popula...

Formation and atomic-scale characterization of an interfacial β-Si 3 N 4 nanolayer in a C/SiC composite

Abstract β-Si3N4 combines attractive mechanical, thermal, and dielectric properties, yet experimental characterization of its local atomic arrangement and bonding-related electronic structure is often complicated by the sintering additives and intergranular phases present in bulk...

Recent Advances in 3D Printing of Two-Dimensional Materials and Devices

Two-dimensional (2D) materials offer opportunities for constructing functional devices; however, integrating them into macroscopic structures requires precise control over nanosheet dispersion, processing parameters, and structural design. This review summarizes research on the f...

Energy-dependent competing pathways in the plasma processing of fused silica: from topology-selective relaxation to network disordering

Oxygen-plasma processing can attenuate polishing-induced topographic features on fused silica, whereas increasingly energetic bombardment can disorder the near-surface network. Atomic force microscopy, Raman spectroscopy, laser-damage measurements, plasma diagnostics, and molecul...
