Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Design and Optimization of Inductive Wireless Power Transmission System

Modern Electronic Technology, 2018
The inductive wireless power transmission system is actually applied to the principle of magnetic feld coupling, combined with the flexibility of the electrical equipment to achieve flexible and safe power supply. In the realization process of wireless power transmission, the key point lies in the transmission effciency and power transmission capability.

Carboxyphenolate Coordination Frameworks for High‐Voltage Calcium Storage

Advanced Science, EarlyView.
A hexaanionic carboxyphenolate coordination framework, Ca2‐M‐THBPD (M = Mg, Ca, Ba), exhibits ligand‐centered enolate‐quinonoid redox activity enabling tunable, high‐voltage Ca2+ storage (3.5 V vs Ca2+/Ca) modulated by spectator cations. The amorphous structure accommodates reversible divalent‐ion insertion, contributing to enhanced cycling stability ...

Inductance and Electrical Properties of Wireless Power Transmission Coil

Asia-pacific Journal of Multimedia Services Convergent with Art, Humanities, and Sociology, 2016
무선 전력 송수신 기술은 휴대폰이나 전동칫솔 등에 널리 사용되고 있으며, 유연한 충전환경을 제 공하며 전자기기의 크기나 형상 설계에서 좀 더 폭 넓은 자유도를 확보하게 해 준다. 본 연구에서는 ANSYS HFSS 및 Q3D 시뮬레이터를 활용하여, 무선 전력 송수신 코일의 구조 변화에 따라 인덕턴스 및 전기적 특성이 어떻게 변화하는지 조사하였다. Q3D extractor 시뮬레이터에 의해 권선구조 변화에 따른 무선충전 코일의 L 값 변화를 시뮬레이션 하였다. 10턴 2층 구조의 코일의 인덕턴스는 16.4uH 로 계산되었다. 자성재료인 페라이트 소재를 기판으로 사용할 경우 코일의 인덕턴스는 28.0uH로 크게 증가하였다.

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

Cobalt Single‐Atom Catalysts for Ultrafast Sulfamethoxazole Degradation: Unveiling the Chloride‐Ion‐Enhanced Formation of Co(IV)=O

Advanced Science, EarlyView.
An atomically dispersed Co–N4 single‐atom catalyst rapidly activates peroxymonosulfate to remove the antibiotic sulfamethoxazole from water. Common ions have little impact, but chloride dramatically speeds degradation by promoting a high‐valent Co(IV) = O oxidant via in situ HOCl–catalyst electron transfer.
