TDLAS技术温度测量的不确定度分析方法研究

open access: yes, 2020
随着可调谐二极管激光吸收光谱(TDLAS)技术在工业测量与科学研究领域的广泛应用,对其测量结果的质量进行量化评定已成为迫切需要。以一套已集成的TDLAS测温系统为例,根据最新国家标准,基于不确定度传播律,理论分析了影响测温结果测量不确定度的因素,给出了评定TDLAS测温系统在线测量结果不确定度的一般方法。分析表明TDLAS系统测温结果的测量不确定度随所测温度值的变化而变化,并受所选谱线参数、吸收信号信噪比、系统响应情况等条件的影响。理论推导了针对测温系统的不确定度评定公式 ...

Surface‐Enhanced Raman Scattering‐Based Multimodal Medical Imaging in Cancer Diagnosis and Therapy Monitoring

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Laser‐Induced Graphene/AuNPs‐Gated OECT Biosensor for Sensitive Detection of PD‐L1‐Positive Exosomes Associated With Non‐Small Cell Lung Cancer

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lung cancer remains a major cause of cancer‐related mortality worldwide, and non‐small cell lung cancer (NSCLC) accounts for the largest proportion of diagnosed lung cancer cases. Exosomal programmed death‐ligand 1 (PD‐L1) has attracted increasing attention as a potential liquid‐biopsy biomarker associated with tumor immune regulation; however,

Advanced Electrospun Nanofiber Epidermal Electronics for Electrophysiological Monitoring: From Conformal Interfaces to Multimodal Closed‐Loop Systems

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Epidermal bioelectronics is a transformative technology for continuous health monitoring and human‐computer interaction. However, the mechanical and physiological mismatch at the skin–device interface limits its long‐term application. Electrospun nanofiber membranes (ENMs), with their unique three‐dimensional hierarchical porous network and ...
