This review summarizes the representative works of MOFs for gas adsorption/separation in recent years, analyses the host–guest interaction, structure–performance relations, and the adsorption/separation mechanism.

The review of synergistic influence of optical, electric, magnetic, and thermal physical fields on the LSPR-assisted photocatalysis. Numerical methods with nano-scale visualization and decoupling calculations are specifically discussed.

This review summarizes the recent research progress in all-inorganic perovskite nano-scintillators in terms of their potential applications in X-ray imaging and provides references on scintillation performance control for future material design.

Bone defect repair caused by trauma, congenital malformation, tumors, infection or systemic diseases remains the focus of attention in regeneration medicine.

Owing to the great development potential of porous anodic oxides (PAO) in many fields, research on their formation mechanisms, fabrication processes and applications has a history of more than ten years.

Few-layer WS₂ or WSe₂ nanosheets were grown on W substrates by CVD, and feather-like WSe₂ delivered excellent performances as HER electrocatalyst in acid including low overpotential of 141 mV to yield 10 mA cm⁻², outperforming other TMDs thin films.

Traditional MW ablation may result in insufficient ablation and aggravation of tumor hypoxia. Our strategy for MW ablation with ZIF67@Gr-PEG NCs achieved the combined effects of enhanced MW ablation and tumor hypoxia relief.

Plasmon-driven photocatalytic effects generate azo reactions.

The ferroelectric Hf_0.5Zr_0.5O₂/antiferroelectric Hf_0.5Zr_0.5O₂ bilayer nanofilms are fabricated by plasma-enhanced atomic layer deposition for on-chip energy storage capacitors, demonstrating a superhigh energy storage density of 364.1 J cm⁻³.

A reconfigurable chiral metasurface is demonstrated with a three-layer structure of complementary split ring resonator arrays. Functional layer with tunable elements provides a platform for tunable polarization response and asymmetric transmission.

We report the excellent sensing performance and health detecting applications of a flexible capacitive pressure sensor based on a Ti₃C₂T_x (MXene)/polyvinyl pyrrolidone (PVP) composite nanofiber membrane.

Nanopore technology has attracted extensive attention due to its rapid, highly sensitive, and label-free performance.

Hybrid metasurface nanostructures composed of ZnO nanopillars and Ag nanoholes exhibit color tunability.

The designed MoS₂/MXene/nickel foam heterostructure displays an ultralow overpotential of 94 mV with a Tafel slope of only 59 mV dec⁻¹ in alkaline hydrogen evolution reaction, due to the more active site and the improved conductivity.

CuCDs enhanced the Fenton reaction activity for rhodamine B degradation. Electron transfer happening on the surface of CuCDs and more ˙OH and ¹O₂ generation played vital roles in RhB degradation. RhB degradation filtrates exhibited low toxicity.

A direct spraying method on a glass surface to obtain Cu₇S₄/silicone sol coatings with high transparency, good photothermal conversion, effective anti-/de-icing behavior, and excellent chemical/physical stability.

Ultrasmall Au–Gd NCs with high-Z elements were used to perform dual-modal (NIR-II fluorescence and MRI) imaging-guided sensitization of tumor radiotherapy.

A multi-band metamaterial absorber in the terahertz regime using a periodically arranged surface structure placed on an ultra-thin insulating dielectric slab backed by a metallic ground plane is demonstrated in this paper.

In this work, Co-SnO₂ NPs with zero-dimensional structure were synthesized by hydrothermal method. At the optimal temperature, the selectivity and response of 0.5% Co-SnO₂ to formaldehyde are excellent (for 30 ppm formaldehyde, R_a/R_g = 163 437).

We report a comprehensive study to investigate the loading mechanism of DOX into the tetrahedral DNA nanostructure by using molecular simulations.
