Measuring Policy Performance, Democracy, and Governance Capacities: A conceptual and methodological assessment of the Sustainable Governance Indicators (SGI)

European Policy Analysis, Volume 8, Issue 2, Page 136-159, Spring 2022., 2022
Abstract This paper provides a critical assessment of the Sustainable Governance Indicators (SGI) and compares it with other prominent indices that address specific components of governance: V‐Dem, WGI, and BTI. We offer a comparative assessment of content validity of these governance measures, their data generation processes, and their convergent ...

Recent Advances in Piezocatalysis and Piezo‐Photocatalysis in Energy and Environment: Materials, Design, and Applications

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Piezocatalytic technology utilizes mechanical strain or stress‐induced piezoelectric phenomena to produce robust internal electric fields, markedly improving the separation efficiency of e−‐h+ pairs. This method has emerged as a focal point in catalysis by removing reliance on conventional light or electrical energy via its mechanical‐to ...

h‐BN/HfO2 Interface‐Enabled Optoelectronic Doping for Low‐Voltage, Reconfigurable MoTe2 Nanoelectronics

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Engineering the semiconductor/dielectric interface is crucial for advancing two‐dimensional (2D) nanoelectronics, where device performance is predominantly governed by interfacial defects and dielectric coupling. Optoelectronic doping based on carrier trapping at the h‐BN/SiO2 interface has enabled non‐volatile and reversible carrier ...

Engineering a Tumor‐Targeted MgH2@Lip/PD‐L1 Nanoplatform for Synergistic Hydrogen Therapy and Immune Activation

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

Excellent Comprehensive Electromechanical Properties in PZT‐Based Hard High‐Temperature Piezoceramics

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

电气设备局部放电融合诊断与智能预警系统研究

Gaoya dianqi, 2021
为降低电气设备内部潜伏性局部放电缺陷导致运行设备发生突发性绝缘击穿故障次数,文中以某在运126 kV GIS设备绝缘放电为对象,进行电气设备局部放电融合诊断与智能预警系统研究。基于局部放电过程中表征出的声电信号特征与在线监测方法,采用动态频率采集法与云平台的形式设计了一套局部放电融合诊断系统,完成设备内部局部放电信号的采集与缺陷的初步定位。通过局部放电时间间隔内信号均值、标准差、最大值等状态图变量的分析,将缺陷状态分为平稳发展阶段与高击穿风险阶段 ...

Research on Ingot Casting of Solar-grade Silicon from Physical Process Route [PDF]

, 2016
目前晶体硅太阳电池占据光伏发电的主流市场，多晶硅太阳电池占晶体硅太阳电池70％以上。多晶硅市场竞争日趋激烈，物理法因其安全、环保、低能耗的优势，未来可能成为生产太阳能级多晶硅的主流技术之一，于是研究高效的物理法太阳能级多晶硅铸锭工艺具有重要的意义。由于物理法制造的太阳能级硅中同时存在B和P元素，二者的分凝系数分别为0.8和0.35，导致其铸锭顶部容易出现p-n转型，从而大大降低了p型多晶硅锭的得率；另一方面，物理法多晶硅金属杂质的含量也会影响多晶硅锭的得率。本论文研究了高效坩埚 ...
