Mechanisms of Temperature‐Dependent Hysteresis in Freestanding BaTiO3/MoS2 Heterostructures

Advanced Science, EarlyView.
Freestanding ferroelectric BaTiO3 membranes are combined with monolayer MoS2 into 2D field‐effect transistors. At room temperature they provide ultrahigh‐κ gating with steep subthreshold swing and minimal hysteresis. Upon cooling, strong ferroelectric switching produces two stable memory states with long retention times.

Genetic diversity at the C-terminal domain of knob-associated histidine-rich protein (KAHRP) of Plasmodium falciparum isolates from Burundi, Eastern Africa

Annals of Medicine and Surgery, 2018
The knob-associated histidine-rich protein (KAHRP) is an exported parasite protein and the major component of infected erythrocytes by Plasmodium falciparum. P. falciparum histidine-rich protein-1 (PfHRP-1) is docked by KAHRP, which this interaction plays a significant role in cytoadherence of the malaria protozoan to erythrocytes and pathogenicity ...

Designer Moiré Quantum Materials Enabled by Freestanding Oxide Membranes in Twisted and Hybrid Bilayers

Advanced Science, EarlyView.
Freestanding oxide membranes transform twistronics by enabling deterministic stacking, strain release, and integration with two‐dimensional materials. A unified framework links local atomic registry to structural reconstruction, polar textures, charge modulation, flat bands, and magnetic responses, while identifying the fabrication and characterization

Emergence of Unconventional Magnetic Order in Strain‐Engineered RuO2/TiO2 Superlattices

Advanced Science, EarlyView.
Epitaxial strain activates unconventional magnetism in rutile RuO2, absent in bulk or relaxed RuO2. Polarized neutron reflectometry with atomic‐layer resolution directly reveals finite magnetization confined to RuO2 layers in fully strained RuO2/TiO2 superlattices on TiO2 (110).

A Spin–Orbit Torque Knob to Tailor Stochasticity for Physically Secured Applications

Advanced Electronic Materials
The deterministic switching of spin–orbit torque (SOT) memory has long been the primary challenge for implementation. Conversely, stochastic switching has recently sparked significant interest for physically secured applications.

Spin Splitting Coupled Visible‐Light Driven Injection Photocurrent in Bilayer Altermagnets

Advanced Science, EarlyView.
Interlayer engineering in bilayer altermagnets continuously tunes visible‐light injection photocurrents, accompanied by controllable altermagnetic spin splitting. Enhanced interlayer hybridization reconstructs the band and quantum geometries, leading to opposite evolution of the normal and magnetic injection currents and establishing a direct ...

Bacteria‐Derived 1‐Allylpiperazine Alleviates Symptoms of Parkinson's Disease Model by Promoting Autophagy

Advanced Science, EarlyView.
Parkinson's disease currently has no disease‐modifying therapies. In Caenorhabditis elegans, Escherichia coli E8 alleviates α‐synuclein‐provoked PD‐related defects through its bioactive metabolite 1‐ALPP, which combats PD by triggering AMPK/mTOR/HLH‐30‐dependent autophagy and suppressing α‐synuclein LLPS‐mediated fibrillization.

Balancing Carrier Cooling in InN/GaN Quantum Wells via Point Defect Engineering

Advanced Electronic Materials, EarlyView.
Nitrogen vacancies in the InN/GaN interface regulate carrier relaxation in polar quantum wells by reconstructing the conduction‐band decay pathway and enhancing nonadiabatic coupling. No deep midgap state is introduced in the neutral single‐vacancy model, enabling faster hot‐electron cooling, improved electron‐hole balance, reduced electron overflow ...

Core and π‐Bridge Engineering to Deconstruct Y6‐Series into Modular Non‐Fused Acceptors: DFT‐Guided Structure‐Property Map for Organic Solar Cells

Advanced Electronic Materials, EarlyView.
The rigid fused backbone of Y6‐series acceptors is deconstructed into a modular, non‐fused A‐π‐A′‐π‐A architecture. Comprehensive quantum chemical simulations reveal that strategic core and π‐bridge engineering preserves strong near‐infrared light‐harvesting and enhances intramolecular charge‐transfer character.

Engineering Ferrimagnetic Interactions in Molecular Quantum Systems

Angewandte Chemie, EarlyView.
Heterospin nanographene architectures—constructed by covalently linking spin‐1/2$\nicefrac {1}{2}$ and spin‐1 triangular units via on‐surface synthesis—are characterized by bond‐resolved scanning probe microscopy. Inelastic electron tunneling spectroscopy probes exchange interactions within a Heisenberg model, revealing both compensated (S=0$S=0$) and ...
