This review summarizes the advances in solar cells based on PbX CQD inks, including both lab-scale and large-area photovoltaic devices.

The nanoarchitectonics concept has the ability to bridge nanoscale science and visual size materials. The final goal of nanoarchitectonics approaches is the creation of living-creature-like functional material systems from simple nanoscale objects.

In this review article, we focus on recent advances in the detection of biomolecule activities based on lanthanide luminescent systems, including UCNPs, Ln-MOFs, and lanthanide organic complexes.

This review describes state-of-art techniques and knowledge on the creation of high-performance heterogeneous catalysts using atomically precise metal nanoclusters.

The integration of various materials and technologies enables the intelligent SDLG biosensor to detect the different types of targets with high sensitivity and generate diversified output signals.

A new Ag₇₀(TBBT)₄₂(TPP)₅ nanocluster with a decahedral Ag₂₃ core is reported which show the complex secondary structure of a double helical 4H (DH4H) close packing pattern in its crystal lattice.

With steady-state density functional theory (SS-DFT), we predict a novel type of nonequilibrium effect that is beyond the DFT based method, which explains ‘puzzling’ transport properties of silane molecules observed in experiments.

The smart nanoparticles may provide a combinatorial spatiotemporal platform against tumors for chemotherapy and the CRISPR/Cas gene-editing system with the advantages of a tumor pH response, active EGFR targeting, and nuclear localization.

Low limiting potential, high product selectivity, strong visible light absorbance and satisfactory band edge positions make Cu₂S monolayers a very compelling photocatalyst for CO₂ reduction.

All-optical switching of magnetic materials, particularly done by the laser beam with orbital angular momentum, is a potential method for realizing high-efficiency and high-speed data writing in spintronics devices.

We report the synthesis of Zn-based polyoxometalate (ZnPOM) and its application in photocatalytic CO₂ reduction to CH₄.

Novel nanoMof (Tf-LipoMof@PL) can induce both ferroptosis and pyroptosis by iron and ROS enrichment, which provides new choices for anti-cancer therapy.

A Pd/HNb₃O₈ flexible humidity sensor is developed with long-term stability at a high humidity level (∼90% RH). Using the sensor, wireless monitoring of human respirations and finger moisture variation under exercise is successfully demonstrated.

Exploring the influence of interlayer interaction on SERS performance by using 2D PtSe₂ and ReS₂ with different numbers of layers as the research objects.

Tricolored white lighting quantum dot-light-emitting diodes comprising three environmentally benign primary color emitters of II–VI blue and green ZnSeTe and I–III–VI red Zn–Cu–In–S QDs are demonstrated.

Recently, various efforts have been made to implement synaptic characteristics with a ferroelectric field-effect transistor (FeFET), but in-depth physical analyses have not been reported thus far.

A simple π-conjugated oligomer nanotheranostic with intrinsic multifunctionality was developed for 808 nm laser-triggered effective NIR-II fluorescence/photoacoustic imaging and photodynamic/photothermal synergistic therapy.

Freshly cleaved BPNR edges are reconstructed into highly stable ones dominated by three bond configurations: double PP bonds, P(2)–P(4) with two lone pairs on one P atom and that with all P atoms having three sp³ bonds.

A photosensitizer-based nanoplatform demonstrated amplified photodynamic immunotherapy by tumor microenvironment modulation.

Self-assembled dasatinib nanoparticles exhibited aggregation-induced emission with high antitumor activity.
