Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum

Advanced Materials, EarlyView.
Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Ultrasound‐Actuated Gene Editing in Human Kidney Organoids

Advanced Science, EarlyView.
Peptide‐stabilized nanoemulsions enable spatially controlled, ultrasound‐triggered delivery of gene‐editing proteins deep within human kidney organoid tissues. Focused acoustic pulses drive droplet vaporization, propelling cargo into target renal cells while preserving native tissue microarchitecture. This non‐viral platform improves both the depth and

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

High‐Performance Multi‐Walled Carbon Nanotubes‐Organic Passivated Si Solar Cells Enabled by Spatially Selective Harvesting of High‐Quality Sponges

Advanced Science, EarlyView.
Our work achieves an efficiency breakthrough in MWCNTs/Si solar cells by screening high‐quality pristine MWCNTs without any separation or purification processes. This breakthrough is mainly attributed to the excellent dispersibility of Nafion and the excellent hole transport property of MWCNTs:Nafion film containing charge transfer doping, passivation,

Efficient Hot Carrier Management in Lead Halide Perovskite Micro‐Disks Revealed by Super‐Diffusive Migration

Advanced Science, EarlyView.
Hot‐carrier transport in metal halide perovskites is investigated using spatiotemporally‐resolved photoluminescence microscopy. Mesa‐shaped MAPbBr3 microdisks exhibit anomalous super‐diffusive carrier propagation on nanosecond timescales, driven by hot‐carrier stabilization and strong carrier–phonon coupling.
