160 GHz Schottky Diodes from Solution‐Processed IGZO

Small, EarlyView.
A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.

Ultrasensitive MicroRNA Detection Combining Reduced Graphene Oxide Electrolyte‐Gated Transistors and Machine Learning

Small, EarlyView.
We developed an ultrasensitive and highly selective biosensor by integrating bio‐functionalized reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) and machine learning (ML) to detect miRNAs (miR‐34a, miR‐34b, and miR‐34c) associated with cancer and neurological disorders.

Defect‐Passivating and Dense Indolocarbazole‐Based Self‐Assembled Monolayers for Efficient Inverted Perovskite Solar Cells With over 26.1% Efficiency

Small, EarlyView.
This study proposes a strategy to modulate nitrogen positions (meta‐/para‐) in indolocarbazole units and the number of anchoring groups (mono‐/bis‐phosphonate), achieving a remarkable PCE of 26.12%, among the highest reported for PSCs using indolocarbazole‐based SAMs as HTLs.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
