Colossal Seebeck Coefficient of Hopping Electrons in (TMTSF)2 PF6

, 2016
International audienceWe report on a study of the Seebeck coefficient and resistivity in the quasi-one-dimensional conductor (TMTSF)2 PF6 extended deep into the spin-density-wave state. The metal-insulator transition at TSDW=12  K leads to a reduction in

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

Advanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

Angewandte Chemie, EarlyView.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...
