Gaoya dianqi, 2018 为了研究电流畸变情况下油浸式配电变压器负载损耗和绕组热点温度的变化规律,基于IEEE StdC57.110中的绕组涡流谐波损耗因子和杂散谐波损耗因子,并考虑绕组在谐波电流下的集肤效应会增强,定义了绕组电阻谐波损耗因子,从而建立了变压器在谐波电流下负载损耗计算模型。考虑到绕组涡流损耗密度分布不均对绕组热点温度的影响,利用文中所建立的变压器在谐波电流下负载损耗计算模型修正了IEEE Std C57.110:2008的绕组热点温度计算公式。分析结果表明,谐波电流会引起较大的额外负载损耗,谐波畸变率为40 ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Dielectric polymers commonly suffer from severe performance degradation above 150°C, hindering advanced power systems. Herein, we demonstrate a polyetherimide (PEI) nanocomposite that overcomes this by mimicking the gradient architecture of nacre and bamboo, incorporating a continuous vertical gradient of fluorinated boron nitride nanosheets ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Because magnetic permeability is an intrinsic property of materials, achieving the regulation of magnetic loss is one of the challenges for electromagnetic wave absorption materials. This paper focuses on the research idea of in situ growth of dispersed nanocrystalline FeSiB in an amorphous FeSiB matrix to regulate magnetic properties.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.
