Unlocking Klockmannite: Formation of Colloidal Quasi‐2D CuSe Nanocrystals and Photo‐Physical Properties Arising From Crystal Anisotropy

Small, EarlyView.
Thiol‐free hot injection approach yields quasi‐2D klockmannite CuSe nanocrystals, specifically nanosheets and uniform triangular nanoplatelets. This study reconsiders the klockmannite from the point of view of crystal anisotropy and demonstrates its effect on plasmonic response in the near‐infrared spectral region with the theoretical emergence of ...

Multifunctional Superwetting Sea‐Urchin‐Mimetic Nanosheet‐Based Interface for Remote Oil‐Water Separation

Small, EarlyView.
A fluorine‐free, FBC–rGO coating‐based robust superhydrophobic/superoleophilic sorbent (WCA >154°), enabling rapid, selective oil uptake and efficient oil/water separation. Integrated into a dolphin‐inspired Wi‐Fi mini‐bot with onboard pumping and storage, the platform enables remote, contactless, on‐site oil recovery from hazardous spill zones ...

Twists and Turns of Liquid Crystals Unravelled by Small‐Angle Scattering

Small Methods, EarlyView.
X‐ray scattering provides valuable insights into material structure and self‐assembly. This review discusses the use of small‐ and wide‐angle X‐ray scattering (SWAXS) as well as grazing incident SWAXS for examining self‐assembled systems, especially liquid crystals.

Machine Learning‐Driven Nanopore Sensing for Quantitative, Label‐Free miRNA Detection

Small Methods, EarlyView.
Nanopore sensors combined with DNA‐barcoded probes enable detection of multiple biomarkers in parallel at the single‐molecule level through characteristic delays in ionic current signals. Three analytical strategies are compared: moving standard deviation, spectral entropy, and a convolutional neural network (CNN). The CNN achieves superior sensitivity
