Tailored D‐π Conjugation Boosts Piezocatalytic CO2 Reduction in a Platinum(II)‐Acetylide Framework

open access: yesAdvanced Science, EarlyView.
The highly conjugated metalII‐acetylide framework demonstrates efficient ultrasound‐driven conversion of CO2 to CO. The piezoelectric field generated by ultrasound facilitates electron transfer from the tetraphenylene π‐column to the MII‐bis(acetylide) moiety, enabling CO2 activation. Compared to PdII‐ and NiII‐based analogues, the stronger d–π orbital

Dipolar magnetic field by static current loop in exponential metric

open access: yesEuropean Physical Journal C: Particles and Fields
We investigated the dipolar magnetic field generated by a static current loop around a compact gravitational source described by the exponential metric. Starting from Maxwell’s equations, we derived the expression for the electromagnetic vector potential

Supercritical CO2‐Induced Porous MXene Films for Electromagnetic Interference Shielding and Infrared Stealth

open access: yesAdvanced Science, EarlyView.
The phase transition of supercritical CO2 induces the foaming of dense MXene film without compromise inherent structure of MXene nanosheet. The foamed porous MXene film manifests remarkable EMI shielding and infrared thermal camouflage performances. Moreover, the foaming strategy is broadly adaptable and can be extended to other two‐dimensional films ...

Thin‐Film Thermal Sensors on Chitosan Substrates for Sustainable Transient Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
Fully transient thin‐film temperature sensors are realized on pure chitosan substrates using Mo‐based RTDs and a‐IGZO/Mo thermistors. The devices exhibit high sensitivity, mechanical flexibility, humidity‐aware operation, and complete dissolution in natural solvents.

Dipolar Order Mapping Based on Spin-Lock Magnetic Resonance Imaging. [PDF]

open access: yesNMR Biomed
To quantify the dipolar order relaxation time T1D$$ {T}_{1D} $$ using spin‐lock MRI technique, we introduce a T1D$$ {T}_{1D} $$‐specific ratio, denoted as RATIOdosl$$ {RATIO}_{dosl} $$. A novel rotary‐echo spin‐lock sequence was developed to enable dual‐frequency spin‐lock acquisition.
