Transparent Organic and Metal Halide Tandem Scintillators for High-Resolution Dual-Energy X-ray Imaging

ACS Energy Letters (2023)

Wenyi Shao Tengyue He Jianxin Wang Yang Zhou Peng Yuan

Dual-energy X-ray imaging (DEXI) is a cutting-edge technology that provides more detailed material-specific information than the traditional single-energy X-ray imaging strategy. Herein, we designed and fabricated a top-filter-bottom (TFB) sandwich structure scintillator for high-resolution DEXI within a single exposure. More specifically, the low- and high-energy X-ray photons were sequentially absorbed by the top and bottom scintillators and were efficiently converted into their corresponding emission colors. By discriminating between these different emission spectra of the transparent TFB sandwich structure scintillator, DEXI can provide not only unique X-ray energy information but also an exceptional resolution of approximately 18 lp/mm on stacked images that surpasses most of the reported single-layer organic- and metal halide-based scintillators. The conceptual demonstrations of decomposition and reconstruction in DEXI were also realized on several biological imaging objects. This breakthrough research paves the way for the development of scintillator architectures specifically designed for DEXI.

Machine learning predicts the functional composition of the protein corona and the cellular recognition of nanoparticles

Proceedings of the National Academy of Sciences (2020)

Zhan Ban Peng Yuan Fubo Yu Ting Peng Qixing Zhou

Protein corona formation is critical for the design of ideal and safe nanoparticles (NPs) for nanomedicine, biosensing, organ targeting, and other applications, but methods to quantitatively predict the formation of the protein corona, especially for functional compositions, remain unavailable. The traditional linear regression model performs poorly for the protein corona, as measured by R 2 (less than 0.40). Here, the performance with R 2 over 0.75 in the prediction of the protein corona was achieved by integrating a machine learning model and meta-analysis. NPs without modification and surface modification were identified as the two most important factors determining protein corona formation. According to experimental verification, the functional protein compositions (e.g., immune proteins, complement proteins, and apolipoproteins) in complex coronas were precisely predicted with good R 2 (most over 0.80). Moreover, the method successfully predicted the cellular recognition (e.g., cellular uptake by macrophages and cytokine release) mediated by functional corona proteins. This workflow provides a method to accurately and quantitatively predict the functional composition of the protein corona that determines cellular recognition and nanotoxicity to guide the synthesis and applications of a wide range of NPs by overcoming limitations and uncertainty.

Marine Absolute Gravimetric Survey Based on Atomic Gravimeter

Journal of Physics Conference Series (2023)

Zhongkun Qiao Peng Yuan Yin Zhou Bin Wu Qiang Lin

Abstract Atomic gravimeter can be used for absolute gravity measurement and has the advantages of low drift, high accuracy and good long-term stability. It can be combined with traditional gravimeter to realize long period and high precision dynamic measurement of gravity field at sea. With the development of relevant technologies and the increasing demand of the application market, mobile and miniaturized atomic gravimeters at home and abroad have stepped out of the laboratory and gradually tried to measure absolute gravity in dynamic environments on platforms such as vehicle, ship and airborne. Based on the Marine atomic gravity measurement system of Zhejiang University of Technology, this paper introduces the system composition, measurement principle and existing difficulties. Based on this system, the first Marine absolute gravity network measurement in China is carried out, and the accuracy of repeated internal check is better than 1mGal.

Copper Iodide Inks for High-Resolution X-ray Imaging Screens

ACS Energy Letters (2023)

Tengyue He Yang Zhou Peng Yuan Jun Yin Luis Gutiérrez‐Arzaluz

Copper-based halide scintillators have attracted considerable interest because of their high light yields, low detection limits, low toxicity, and moderate fabrication conditions. Here, we synthesized two Cu(I) iodide inks, comprising zero-dimensional Cu4I6(L1)2 nanoparticles (L1 = 1-propyl-1,4-diazabicyclo[2.2.2]octan-1-ium) and one-dimensional Cu4I6(L2)2 nanorods (L2 = 4-dimethylamino-1-ethylpyridinium) for X-ray imaging application. The Cu4I6(L1)2 nanoparticles and Cu4I6(L2)2 nanorods exhibited broadband green and yellow emission with an ultrahigh photoluminescence quantum yield of 95.3% and 92.2%, respectively. Consequently, the two Cu(I) iodide ink-based X-ray screens exhibited low detection limits of 96.4 and 102.1 nGy s–1, respectively, which are approximately 55 times lower than the dose required for standard medical diagnosis (5.5 μGy s–1). Importantly, both the scintillation screens exhibited extraordinary X-ray imaging resolutions exceeding 30 lp mm–1, more than double those of the conventional CsI:Tl and Ga2O2S:Tb scintillators. This study provides a new avenue for exploring high-resolution X-ray imaging screens on the basis of Cu-based halide ink for medical radiography and nondestructive detection.

Noise Processing of Ocean Absolute Gravity Data Based on Savitzky-golay Filtering Algorithm

Journal of Physics Conference Series (2023)

Peng Yuan Zhong-kun Qiao Dong Zhu Yingpeng Zhao Yin Zhou

Abstract High-precision data on absolute gravity have a wide range of applications, including basic science, resource exploration, national defense infrastructure, seismic studies, and inertial navigation, among others. The atomic gravimeter, known for its high sampling rate, accuracy and long-term stability, is particularly well suited for high-precision measurements of absolute gravity in oceanic and deep-sea environments. However, the challenging conditions found in the ocean introduce significant noise into the gravity data obtained from atomic gravimeters. This noise adversely affects the accuracy of gravity measurements, which in turn affects the interpretation of geological structures. Consequently, the analysis and processing of noise in atomic gravimeter data has become a focal point in the research of high-precision absolute oceanic gravity dynamic measurements. In this study, we conducted absolute gravity measurement experiments using the shipboard atomic absolute gravity measurement system developed at Zhejiang University of Technology. To filter the collected gravity data, we used the Savitzky-Golay (SG) filtering algorithm. This algorithm not only preserves essential measurement information, but also provides superior accuracy compared to conventional filtering methods.
