Abstract

Space application refers to the direct and indirect technology utilization, product production, and service provision on the ground or in space by utilizing space resources, assets, and conditions. After over 60 years of development, the aerospace industry of China has made significant achievements, with over 400 satellites in orbit. However, the system design, basic database, and standards construction that are closely related to space application still cannot satisfy the requirements of high-quality development. Considering the demand for strengthening China's aerospace industry and the medium- and long-term development requirements of the industry, this study reviews the development status of space application in China and abroad, summarizes the new requirements for spaceapplication industry and technologies in China, and analyzes the challenges faced by space application. Moreover, the general ideas, development goals, and top-level systems of space application for strengthening China’s aerospace industry are proposed. The key directions for the development of space application are explored. Furthermore, we suggest that China should improve policies and regulations associated with the aerospace industry, promote the integration of space, ground, and users, and optimize mechanisms and services of the industry, so as to promote the formation of a coordinated space application pattern that features space-ground-user interactive development and unified standards.

Abstract

The demolding process in micro-injection molding constitutes a critical phase, exerting a decisive influence on the quality of polymer microstructures. In this study, the demolding forces of PMMA microfluidic chips were measured under different demolding temperatures, packing pressures, and demolding speeds by using pure nickel (Ni) mold insert. The dimensional deviations of the microchannels with different aspect ratios were analyzed. In addition, the effect of mold insert modification on the demolding force was further analyzed. The results showed that the effect of demolding temperature on the demolding force was the most significant, and the peak demolding force decreased with the decrease in temperature. The width of the microchannels increased and the depth decreased after demolding, while the opposite results were observed for the micro-mixing structures. However, the dimensional deviation of the micromixing structures was larger than that of the microchannels. Using the optimal molding parameters, the peak demolding force could be reduced from 114.0 N at 110[degrees]C to 47.0 N, a decrease of 58.8%. It is noteworthy that, when the microchannel was narrower than 100 [micro]m, achieving precise replication of microchannel dimensions became progressively more challenging as the microchannel width decreased. Using the Ni-W[S.sub.2] mold insert with low surface energy and low friction coefficient, the demolding force could be further reduced by 38.3%. The effect of the molding quality of microfluidic chip microstructures on the mixing performance of heavy metals was demonstrated by micro-mixing experiments. Highlights * Demolding temperature crucially affects microstructure dimensions. * Optimal parameters and modified mold insert reduce demolding force by 38.3%. * Dimensional deviation increases with the increase of microchannel aspect ratio. * Optimized microfluidic chip enhances [Co.sup.2+] chemiluminescence by 6.42%. KEYWORDS demolding force, dimensional deviation, microfluidic chip, micro-injection molding, microstructure, 1 | INTRODUCTION Microfluidics is extensively employed in various fields such as biotechnology, chemical analysis, and medical diagnosis.

Abstract

Microinjection molding has been attracting increasing attention and application in fabricating products with functional surface microstructures. The processing parameters, packing pressure, and melt temperature have important effects on the filling quality. In order to study the mechanisms of the packing pressure and melt temperature on the filling quality of micropillars, a simulation model of injection molding of nanopillars was constructed by molecular dynamics software and a series of injection molding experiments of micropillars were carried out in this paper. Subsequently, the mechanisms were analyzed qualitatively. The results showed that the frozen layers were formed at the interface between the polymer melt and mold under the action of heat transfer, which prevented effective filling of the polymer melt. The filling quality of the micropillars could be improved significantly via increasing the melt temperature and the packing pressure, but the mechanisms were different. To be specific, the increase of the packing pressure could make more polymer melts fill into the cavity fully. Thus, the density of the micropillars was increased and the filling quality could be improved. The forming rate of frozen layers could be slowed down by increasing the melt temperature. As a result, the purpose of improving the filling quality was achieved. KEYWORDS filling quality, melt temperature, micro injection molding, molecular dynamics, packing pressure, 1 | INTRODUCTION Functional surfaces with microstructures generally have regular textures and a certain periodicity of structures, [1] which can be used to realize self-cleaning, drag reduction, super-hydrophobic, antisticking, and [...]

Abstract

The application of microorganisms as probiotics is limited due to lack of safety evaluation. Here, a novel multi-stress-tolerant yeast Meyerozyma guilliermondiiGXDK6 with aroma-producing properties was identified from marine mangrove microorganisms. Its safety and probiotic properties were assessed in accordance with phenotype and whole-genome sequencing analysis. Results showed that the genes and phenotypic expression of related virulence, antibiotic resistance and retroelement were rarely found. Hyphal morphogenesis genes (SIT4, HOG1, SPA2, ERK1, ICL1, CST20, HSP104, TPS1, and RHO1) and phospholipase secretion gene (VPS4) were annotated. True hyphae and phospholipase were absent. Only one retroelement (Tad1-65_BG) was found. Major biogenic amines (BAs) encoding genes were absent, except for spermidine synthase (JA9_002594), spermine synthase (JA9_004690), and tyrosine decarboxylase (inx). The production of single BAs and total BAs was far below the food-defined thresholds. GXDK6 had no resistance to common antifungal drugs. Virulence enzymes, such as gelatinase, DNase, hemolytic, lecithinase, and thrombin were absent. Acute toxicity test with mice demonstrated that GXDK6 is safe. GXDK6 has a good reproduction ability in the simulation gastrointestinal tract. GXDK6 also has a strong antioxidant ability, β-glucosidase, and inulinase activity. To sum up, GXDK6 is considered as a safe probiotic for human consumption and food fermentation.

However, lncRNA NLIPMT, as a novel non-coding RNA, only was studied in breast cancer. This study aimed to explore the role of NLIPMT in esophageal squamous-cell carcinomas (ESCC).Materials and Methods: NLIPMT, miR320 and survivin mRNA in ESCC tissues (or non-tumor tissue) were detected by qRT-PCR. Dual-luciferase reporter assay was performed to assess the relationship between miR-320 and survivin. In ESCC cell lines KYSE510 and ECA109, miR-320 mimic and expression vectors carrying NLIPMT and survivin were used. Cell cycle, apoptosis, proliferation and migration were detected by flow cytometry, CCK-8, transwell assay, respectively. NIPMT, miR-320 and survivin expression were measured by qRT-PCR and Western blotting.Results: NLIPMT was downregulated in ESCC and predicted poor survival of ESCC patients. NLIPMT was positively correlated with miR-320 and negatively correlated with survivin in ESCC tumor tissues. Dual-luciferase reporter assay showed that miR-320 directly regulated survivin. qRT-PCR and Western blotting showed that NLIPMT promoted miR-320 expression and inhibited survivin expression via up-regulating miR-320. Moreover, both NLIPMT and miR-320 overexpression inhibited cell proliferation and migration and promoted cell cycle arrest and apoptosis in ESCC cells, while their effects were abolished by survivin overexpression.Conclusion: We demonstrate that NLIPMT inhibits cell proliferation and migration and promotes cell cycle arrest and apoptosis in ESCC cells by regulating the miR-320/survivin axis. NLIPMT may be a novel prognosis biomarker in ESCC patients.Keywords: ESCC, NLIPMT, survivin, miR-320, tumorigenesis
