Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Diamond Metasurface‐Based Optical Tweezers With Enhanced Robustness

open access: yesAdvanced Science, EarlyView.
Conventional metasurface optical tweezers are hindered by thermal instability from laser heating. This work overcomes this by using diamond metasurfaces, exploiting their low thermo‐optic coefficient and minimal thermal expansion. The platform demonstrates stable particle trapping, translocation, and rotation, enabling robust miniaturized systems for ...

Tri‐Layer Solid‐State Nanopore Arrays with Crosstalk Suppression for High‐Throughput, Femtomolar‐Level Biosensing

open access: yesAdvanced Science, EarlyView.
The critical pore spacing—approximately twenty times the pore radius—required to minimize electric field coupling is determined via finite element analysis. A multi‐layered Al2O3/Au/Si3N4 nanopore structure fabricated by helium ion beam lithography is proposed, enabling quantitative analysis of the target analyte while mitigating inter‐pore crosstalk ...

Revealing Ambipolar Charge Transport in BTBT‐Based D–A–D Molecules via Photo‐MIS‐CELIV Measurements

open access: yesAdvanced Electronic Materials, EarlyView.
We report a new family of D–A–D molecules based on BTBT and BTBTOx4 as central π‐conjugated cores. Using photo‐MIS‐CELIV, we measured hole and electron mobilities and investigated the role of molecular structure. BTBTOx4 derivatives show ambipolar behavior and intrinsic p‐doping, while BTBT analogues are unipolar with higher mobility.

Heterogeneous Integration of Flipped Oxide Heterostructure Membranes for Nanoelectronics

open access: yesAdvanced Electronic Materials, EarlyView.
A flipped electronically reconfigurable STO/LAO freestanding membrane is demonstrated and integrated with various host platforms via controlled transfer. Using ultra‐low‐voltage electron‐beam lithography, conductive nanostructures are created at the buried STO/LAO interface. This novel approach enables heterogeneous integration of flipped complex oxide
