Revealing the Impact of Phase Transition on n = 1 2D Perovskite Photodetectors With Intrinsically Tunable Narrowband Detection

Small, EarlyView.
Spectrally tunable narrowband photoconductors have been achieved based on n = 1 2D perovskite (PEA)2PbBrxI4‐x. Achieved the highest D* of 1011 Jones at 20 V. This research revealed the two different stacking orders in pure compositions and studied phase segregation in mixed halides, which quenched device performance.

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

Small, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators

Small, EarlyView.
We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Prostate cancer diagnosis using plasma extracellular vesicles isolated via aqueous two‐phase systems

VIEW, EarlyView.
Abstract Prostate cancer (PCa) is the second most prevalent cancer in men, with early detection and precise staging remaining critical for improving outcomes. While PSA tests and biopsies are widely used, they suffer from low specificity and often lead to unnecessary procedures.
