Impact of Microplastics and Nanoplastics on HumanHealth

Effects of microplastics and nanoplastics on human health

Maxine Swee-Li Yee et al.

In recent years, plastics have influenced every aspect of people’s daily lives. Plastic waste has quietly poured into human beings, seriously affecting our living environment, and degraded micro/nano plastics are also threatening human health. Early research focused on the environmental impact of micro/nanoplastics, and relatively few studies on human impacts, especially at the subcellular or molecular level. In addition, the three main pathways through which the human body is exposed to micro/nanoplastics—gut, lungs, and skin epithelial cells—have also not been well studied. Based on this, this paper explores the production of nanoplastics, their degradation, toxicity and pollution in the environment, and the impact on human health, and further proposes research.

Transition Metal Oxide Electrode Materials for Supercapacitors: A Review of Recent Developments

Recent advances in transition metal oxide electrode materials for supercapacitors

Ruibin Liang et al.

https://www.mdpi.com/1102524

In recent decades, the consumption of non-renewable fossil fuels has been increasing, seriously threatening human life. Therefore, it is urgent to develop environmentally friendly, low-cost, renewable and reliable energy storage devices. High power density, good cycle stability, and fast charging and discharging processes make supercapacitors the most promising energy devices. However, the energy density of supercapacitors is still lower than that of ordinary batteries. As we all know, the electrochemical performance of supercapacitors depends heavily on the electrode material. This paper first introduces six typical transition metal oxides (TMOs) for supercapacitor electrodes, including RuO2, Co3O4, MnO2, ZnO, XCo2O4 (X = Mn, Cu, Ni) and AMoO4 (A = Co, Mn, Ni, Zn). Secondly, the problems existing in the practical application of these TMOs are proposed, and the corresponding feasible solutions are clarified. Then, the authors summarize the latest progress of 6 supercapacitor electrode TMOs; Finally, the development trend of supercapacitors is discussed, and suggestions are put forward for the development of supercapacitors in the future.

Unravelling Morphological and Topological Energy Contributions of Metal Nanoparticles

Interpretation of morphological and topological energy contributions of metal nanoparticles

Lorena Vega, Francesc Viñes and Konstantin M. Neyman

https://www.mdpi.com/1416478

Metal nanoparticles (NPs) are ubiquitous in many fields such as nanotechnology and heterocatalysis, and their properties are different from single crystal surfaces and blocks. A key aspect is that NP properties depend on size constraints, including different NP shapes, which can skew NP stability based on NP size. In this paper, the authors study the stability of multiple different Pdn NPs (n = 10~1504 atoms) through first-principles energy optimization, so as to determine that icosahedron is the most stable at a size of about 4nm. In NPs larger than this size, truncated octahedrals become more stable, with higher {111} surface stability compared to (001) single crystal surfaces, and lower {001} surface stability compared to (111) single crystal surfaces, so the presence of larger {001} surfaces than the Wulff structure is predicted. NP cohesive energy decomposition expressed in coordination numbers is considered an excellent quantitative tool for stability assessment, with an average absolute error of only 0.01 eVatom-1, while geometric decomposition only allows qualitative stability screening.

Antiviral Activity of Silver, Copper Oxide and Zinc Oxide Nanoparticle Coatings against SARS-CoV-2

Antiviral activity of nanosilver, copper oxide and zinc oxide coatings against SARS-CoV-2

Padryk Merkl et al.

https://www.mdpi.com/1111682

To date, SARS-CoV-2 has triggered a global pandemic and threatened many lives. The spread of contaminants from surfaces, as well as airborne transmission of aerosols, may be the main causes of the spread of the virus. In this paper, the authors deposited three antimicrobial (Ag, CuO, and ZnO) nanoparticle coatings on solid plane and porous filter media and compared them to anti-SARS-CoV-2 properties. These nanocoatings are self-assembled by aerosol nanoparticles during flame synthesis. Among them, nano-Ag particles showed the strongest antiviral activity as a coating, CuO performance was moderate, and ZnO could not significantly reduce the infectivity of the virus. Nano Ag and CuO coatings show some antiviral potential, thus minimizing transmission and hyper-transmission events, while also providing critical information for current and future pandemic mitigation.

Cellulose Nanofiber-Based Nanocomposite Films Reinforced with Zinc Oxide Nanorods and Grapefruit Seed Extract

Zinc oxide nanorods and grapefruit seed extract reinforced cellulose nanofiber-based nanocomposite films

Swarup Roy et al.

https://www.mdpi.com/1053290

The authors present the preparation and characterization of Zinc Oxide Nanorods (ZnOs) and Grapefruit Seed eExtract (GSE) Cellulose Nanofiber (CNF)-based nanocomposite films. The authors separated CNF by combining chemistry and physics, prepared ZnO by simple precipitation, and prepared CNF/ZnO/GSE films with ZnO and GSE as functional nanofillers. Physical characterization (morphology, chemical interactions, optical, mechanical, thermal stability, etc.) and performance tests (antimicrobial and antioxidant activity) have shown that the incorporation of ZnO and GSE does not affect the crystal structure, mechanical properties and thermal stability of CNF thin films. The nanocomposite film is highly transparent and has good UV blocking and vapor blocking properties. In addition, the film has a certain antibacterial and antioxidant effect. The good quality and superior performance of CNF/ZnO/GSE nanocomposite films make them have broad application prospects in food packaging.
