This article discusses the biopolitics of the coronavirus pandemic practiced on both human and non-human animals. I begin by introducing the idea of biopolitics and othering. I then bring two animals, bats and minks, together to explain the role of biopolitics in manipulating the bodies of non-human animals. In particular, I compare the discourses surrounding both animals that frame bats as the wild and minks as the productive— the categorization of both disembodies the animals and subjects them to exploitation. I also examine the role of the environment in creating a shared vulnerability between human and non-human animals. I argue that the coronavirus pandemic is a crisis evoked by a system that profits from the use of biopolitics through the creations of dichotomies between the “normal” and the “abnormal.” To reimagine our future, we need to seek a sustainability that fosters entanglements, instead of separations, of all creatures.

Storage and preservation techniques can play an important role in extending the shelf life of perishable foods. With consumers’ increasing awareness of environmental protection and safety, edible antibacterial packaging is highly favored because of its natural source and non-toxic nature. This paper introduces in detail the substrate materials, antibacterial agents and methods used to prepare edible antibacterial films, summarizes the application of edible antibacterial films in the food packaging field, and discusses future trends in the development of antibacterial food packaging. We hope that this review will provide a reference for reduction in white pollution and the recovery and utilization of agricultural and industrial wastes, and provide a scientific and theoretical basis for food storage and preservation.

With the rapid increase in the use of mobile devices equipped with built-in sensors, mobile crowd sensing (MCS) as a human driven perception mode came into being. Since a large number of users submit data to the cloud servers in parallel, it will not only increase the pressure on the cloud servers, but also lead to the problem of data redundancy. In order to solve this problem, this paper introduces edge computing into mobile crowd sening for collecting perception data, and proposes a group intelligence perception network data collection model based on edge computing. The data is observed and sampled at the edge node through the compressed sensing algorithm, and the compressed data is transmitted to the cloud server.Using Cl_ BP algorithm restores the compressed data in cloud server .The results show that compared with the orthogonal matching pursuit algorithm (OMP), the data collection model based on edge cloud computing proposed in this paper can better solve the problem of data redundancy.

Due to their high porosity, large specific surface area, and structural similarity with the extracellular matrix (ECM), electrospun nanofiber membranes are often endowed with the antibacterial properties for biomedical applications. The purpose of this study was to synthesize nano-structured Sc2O3-MgO by doping Sc3+, calcining at 600 °C, and then loading it onto the PCL/PVP substrates with electrospinning technology with the aim of developing new efficient antibacterial nanofiber membranes for tissue engineering. A scanning electron microscope (SEM) and energy dispersive X-ray spectrometer (EDS) were used to study the morphology of all formulations and analyze the types and contents of the elements, and an X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier transform attenuated total reflection infrared spectroscopy (ATR-FTIR) were used for further analysis. The experimental results showed that the PCL/PVP (SMCV-2.0) nanofibers loaded with 2.0 wt% Sc2O3-MgO were smooth and homogeneous with an average diameter of 252.6 nm; the antibacterial test indicated that a low load concentration of 2.0 wt% Sc2O3-MgO in PCL/PVP (SMCV-2.0) showed a 100% antibacterial rate against Escherichia coli (E. coli).

The toxicity of Mg(OH)2 nanoparticles (NPs) as antibacterial agents to a normal biological system is unclear, so it is necessary to evaluate their potential toxic effect for safe use. In this work, the administration of these antibacterial agents did not induce pulmonary interstitial fibrosis as no significant effect on the proliferation of HELF cells was observed in vitro. Additionally, Mg(OH)2 NPs caused no inhibition of the proliferation of PC-12 cells, indicating that the brain's nervous system was not affected by Mg(OH)2 NPs. The acute oral toxicity test showed that the Mg(OH)2 NPs at 10,000 mg/kg induced no mortality during the administration period, and there was little toxicity in vital organs according to a histological analysis. In addition, the in vivo acute eye irritation test results showed little acute irritation of the eye caused by Mg(OH)2 NPs. Thus, Mg(OH)2 NPs exhibited great biosafety to a normal biological system, which was critical for human health and environmental protection. [ABSTRACT FROM AUTHOR]

The multifunctional polyethylene terephthalate (PET) fabrics were successfully prepared through a dip-coating technology to endow the flame retardant and antibacterial properties of PET fabrics, which are extensively used in many fields. The flame retardant and antibacterial agent was synthesized by a double drop-reverse precipitation method and surface-modified by the mixtures of titanate coupling agents and stearic acid to result in a good compatibility of the hydrophilic nano-Mg(OH)2 and the hydrophobic PET fabrics. The results indicated that the suitable synthesis conditions of nano-Mg(OH)2 are: Mg2+ concentration 1.5 mg/mL, reaction temperature 50 °C and reaction time 50 min, and the optimal modification conditions of nano-Mg(OH)2 are: modifier ratio 5/5, modification temperature 70 °C and modification time 40 min. The flame retardant test and the antibacterial test showed that the multifunctional PET fabrics had excellent flame retardant and antibacterial properties. [ABSTRACT FROM AUTHOR]

Ultrathin multilayer fullerene films have been fabricated for the first time using the layer-by-layer electrostatic self-assembly monolayer method. The highly homogeneous, transparent, micrometer-thick films were characterized by ultraviolet-vis spectroscopy, atomic force microscopy and ellipsometry. The locally domed surface perturbations as well as the average surface roughness values of the fullerene films for one, two and three bilayers were also determined.
