Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots
Post‐synthesis surface engineering and doping control significantly improve the performance of Ag₂Te CQD photodiodes, achieving a low dark current of 450 nA cm−2 at −0.5 V, an LDR exceeding 150 dB, and a rapid response speed of ≈25 ns. A proof‐of‐concept LiDAR demonstration in the SWIR using a nanosecond diode laser, achieves decimetre‐level resolution

Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture
Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.

This study presents core‐shell Au‐Ag NPs and a novel molecularly imprinted polymer (MIP)‐based material targeting L1CAM. Thionine is used as a monomer to create the MIP on a carbon screen‐printed electrode. Functionalized Au‐AgNCs with Raman reporter 4‐mercaptobenzoic acid and anti‐L1CAM enable selective detection via surface‐enhanced Raman scattering ...

A two‐stage sorption mechanism is proposed for Al‐doped HMnO in direct lithium extraction. Batch sorption experiments and modeling identify two key sorption sites on Al‐HMnO: surface sites (planar and edge) and vacancy sites (W). At pH 12, Stage I involves surface ion exchange, followed by Stage II, where surface complexation occurs between Li⁺ ions ...

By doping the elements with different numbers of valence electrons (Al3+ and Sn4+ ions) into the ZnO matrix, device conversion efficiencies of 8.69% and 9.21%, respectively, are achieved. The ultrafast time‐resolved studies show that the elevated carrier concentration in Sn‐doped ZnO, in comparison with Al‐doped ZnO and un‐doped ZnO, plays a ...
