“Lab on paper” is a paper-based microanalytical system with unique advantages such as high sensitivity, low cost, portability, and mass production, which breaks through the limitations of traditional detection technologies and shows great potential in the field of rapid on-site food detection. In this paper, the typical “labs on paper”, including chromatographic paper, chemical test chip, lateral flow assay (LFA), microfluidic paper-based analytical devices (μPADs), and synthetic biological paper, are systematically reviewed. Special emphasis is put on the application of “lab on paper” in the field of food detection. Finally, the advantages, challenges, and future prospects of paper-based analytic methods are discussed, which may provide theoretical support for better application of “lab on paper” in the field of food detection.

- Abstract
Three kinds of commercial ink-jet printing paper were taken as the research objects, which were represented by sample A, sample B and sample C respectively. Sample A and sample C were domestic products Abbott and Jiayi, and sample B was foreign product Gulou. The structure and composition of the three sample coatings were determined, and the surface properties of the three coatings were analyzed. This helps to understand the performance status of inkjet paper products on the market, and has guiding significance for the study of various factors affecting the performance of inkjet paper coatings. AFM and SEM were used to observe the surface morphology of the three samples. It was found that the coating pigment particles of sample A and sample B had good dispersion uniformity, and the coating pigment particles of sample C aggregated and the dispersion uniformity was poor. The results of cross-section SEM and EDS analysis show that only sample B coating has a double-layer structure, in which the bottom layer is aluminum-based pigment and silicon-based pigment, and the surface layer is only aluminum-based pigment. The coatings of sample A and sample C are single-layer aluminum-based materials. The properties of the coating surface of the three samples were analyzed. The results showed that the basic properties of the three samples met the product quality standards. Among them, the coating of sample B had the highest gloss (74.30%), hardness (3H) and water resistance. In terms of ink absorption, the ink absorption of sample B coating (64.7%) was higher than that of sample C (57.9%), slightly lower than that of sample A (69.2%). Sample B had the best comprehensive performance among the three samples. Finally, a double-layer coating process scheme for improving the performance of inkjet printing paper is proposed, which provides a direction for improving the performance of inkjet printing paper and has practical significance for the research of advanced inkjet printing paper.

- Abstract
An ordinary woman gave the birth to a very thin baby, just like paper. Weird things happened again and again and that woman was murdered too. The police started to investigate. The suspect caught by the police admitted to the crime. However, on the trial day, the murderer disappeared under the close watch of court's guards...... Everything happened was so weird. At the same time, a frozen infant body was found in Korea. After the examination by forensic doctor He Xi, it was found that the frozen infant had very strong muscles. The most important thing was that the frozen infant had a rare blood type, just the same as the murdered lady......What kind of terrible power in the back manipulated this? This book would be the most unbelievable book!

Fruit paper is a paper-shaped snack made from fresh fruit after pulping, boiling and drying. Drying, one of the oldest methods for food preservation, removes water from fruit and extends its shelf-life for year-round consumption. The most commonly used drying methods include hot air drying, vacuum drying, freeze drying, and their combinations. The energy efficiency of drying process and the quality of fruit paper are both important to be considered in fruit pulp drying. This article updates the research status of drying technologies applied in fruit paper production, including hot air drying, freeze drying, vacuum drying, microwave drying, infrared radiation drying, and refraction window drying. In addition, the influence of the pretreatments and drying process on fruit paper's shape, texture, and nutrients are also summarized. This work aims to improve the drying efficiency of fruit paper and retain the active ingredients of fruit to the maximum extent, and to provide reference for further research on drying processing of fruit paper in food industry.

Knowledge representation of scientific paper data is a problem to be solved,and how to learn the representation of paper nodes in scientific paper heterogeneous network is the core to solve this problem.This paper proposes an unsupervised cluster-level scientific paper heterogeneous graph node representation learning method(UCHL),aiming at obtaining the representation of nodes (authors,institutions,papers,etc.) in the heterogeneous graph of scientific papers.Based on the heterogeneous graph representation,this paper performs link prediction on the entire heterogeneous graph and obtains the relationship between the edges of the nodes,that is,the relationship between paper and paper.Experiments results show that the proposed method achieves excellent performance on multiple evaluation metrics on real scientific paper datasets.

- Abstract
Utilizing the iron-carbon microelectrolysis technology to carry out in-depth treatment of waste paper and pulp wastewater, the optimal process parameters were determined based on single factor experiments. In addition, the response surface methodology was employed to optimize the process parameters by analyzing the experimental results. Under the optimized conditions, the excita1tion-emission-matrix spectra and GC-MS were used to analyze the water quality of the treated wastewater. The results showed that the optimal treatment conditions of iron-carbon microelectroly1sis process were initial pH=3.0, filler addition amount 255g L-1, reaction time 120 min, aeration amount 0.9 L min-1, and the COD removal efficiency was 32. 14% under these conditions; the maximum predicted value of COD removal rate calculated under the optimal process conditions was 34.57% from the response surface analysis, which was basically consistent with the experimental results. The results of excitation-emission-matrix spectra analysis showed that the iron-carbon micro1electrolysis process was effective in degrading humic acid and fulvic acid in waste paper and paper wastewater, and GC-MS analysis showed that the relative content of eicosanoids in wastewater was reduced from 43.31% to 4.79% of the original water after the iron-carbon microelectrolysis treat1ment, but a small amount of new pollutants were generated at the same time.
