CRISPR‐Cas9‐Loaded Theranostic Liposomes for Enhancing Radiosensitization of Prostate Cancer through POLD4 Gene Editing under Real‐Time MRI Monitoring

Advanced Science, EarlyView.
This study identifies POLD4 as a potential prostate cancer radiosensitization target through transcriptome sequencing. By encapsulating POLD4‐targeted CRISPR/Cas9 plasmids and USPIONs in cationic liposomes, an MRI‐monitored gene‐editing platform is established.

Dynamics of parametric fluctuations induced by quasiparticle tunneling in superconducting flux qubits

, 2014
We present experiments on the dynamics of a two-state parametric fluctuator in a superconducting flux qubit. In spectroscopic measurements, the fluctuator manifests itself as a doublet line.

Cation–Anion Synergy Enables Uniform and Stable SAMs for High‐Efficiency Perovskite/TOPCon Tandem Solar Cells

Advanced Science, EarlyView.
A cation‐anion synergistic strategy is developed to enhance self‐assembled monolayer (SAM) adsorption using guanidinium thiocyanate (GuaSCN). Guanidinium (Gua⁺) suppresses micelle aggregation, while thiocyanate (SCN−) promotes phosphonic acid deprotonation and strengthens ionic bonding to the substrate.

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

Advanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.

C-axis Josephson Tunneling Between YBCO and Pb: Direct Evidence for Mixed Order Parameter Symmetry in a High-T_c Superconductor

, 1997
We report a new class of $c$-axis Josephson tunneling experiments in which a conventional superconductor (Pb) is deposited across a single twin boundary of a YBa_2Cu_3O_{7-\delta} crystal.

In Situ Quantization with Memory‐Transistor Transfer Unit Based on Electrochemical Random‐Access Memory for Edge Applications

Advanced Science, EarlyView.
By combining ionic nonvolatile memories and transistors, this work proposes a compact synaptic unit to enable low‐precision neural network training. The design supports in situ weight quantization without extra programming and achieves accuracy comparable to ideal methods. This work obtains energy consumption advantage of 25.51× (ECRAM) and 4.84× (RRAM)
