Comparison of cryogenic and non-cryogenic droplet impact dynamics at low Weber numbers

open access: yesScientific Reports
Cryogenic fluids are crucial in applications such as rockets, cryosurgery and energy storage, where they can come in contact with surfaces. Thus, their impact dynamics are of interest.

NIR‐II Imaging‐Guided Photothermal Activation of a TRPV4‐Targeted Nanoplatform Delivering Cycloastragenol to Promote Microglia Reprogramming and α‐Synuclein Clearance in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Current therapies for Parkinson's disease (PD) fail to concurrently address α‐synuclein (α‐syn) aggregation and microglia‐mediated neuroinflammation. Herein, we engineer a near‐infrared‐II (NIR‐II) phototheranostic nanoplatform, CAG/FD1080@MM‐aTRPV4, for synergistic regulation of microglial function and real‐time monitoring of PD pathology. We

Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

Molecularly Engineered Phenoxazinone‐Skeleton Cascade‐Activated NIR Probes for Monitoring Fe2+/Viscosity in Ferroptosis‐Mediated Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A series of Fe2+/viscosity cascade‐activated NIR fluorescence probes (NP1–5) are synthesized, and NP3 is selected for its optimal properties. To verify application of NP3 in ferroptosis intervention in PD, PQR NPs, is constructed by NP3 and quercetin self‐assembling.

Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

open access: yesAdvanced Science, EarlyView.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

Modulating Persistent Photoconductivity through Barrier Engineering for High‐performance and Multifunctional Two‐dimensional Optoelectronic Devices

open access: yesAdvanced Science, EarlyView.
Schottky barrier engineering using van der Waals contacts enables effective modulation of persistent photoconductivity (PPC) in optoelectronic devices. A high persistent photoconductivity gain (PPCG) (307.6%) is achieved in a high‐barrier Au/MoS2 junction, supporting photomemory and optoelectronic synaptic behaviors. A low PPCG (4.72%) is achieved in a
