Interrelation between radio and X-ray signatures of drifting subpulses in pulsars

open access: yes, 2006
We examined a model of partially screened gap region above the polar cap, in which the electron-positron plasma generated by sparking discharges coexists with thermionic flow ejected by the bombardment of the surface beneath these sparks.

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

特高压GIL用伸缩节的研制及型式试验

open access: yesGaoya dianqi, 2022
苏通GIL综合管廊工程采用隧道中敷设特高压GIL的方式跨越长江,是目前世界上电压等级最高、输送容量最大、技术水平最高的超长距离GIL创新工程。伸缩节是GIL的关键部件,起到补偿GIL设备安装误差以及GIL筒体的热胀冷缩等的作用,对GIL整体柔性设计至关重要。苏通GIL综合管廊工程可靠性要求极高,对伸缩节提出了大补偿量、高气密性、较小基础作用力和长寿命的综合技术要求,伸缩节的设计制造难度很大。本文介绍了特高压GIL用伸缩节的技术参数、选型依据和结构设计,研制了大尺寸直管压力平衡型伸缩节,总长1.8 m ...

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

open access: yesAdvanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

open access: yesAdvanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...
