Summary: Previous studies have mainly focused on the growth performance and intestinal inflammation of porous or nano particles zinc oxide (ZnO) in piglets, but little is known about its effect on gut microbiota. This study found that dietary 500 mg/kg porous or nano particles ZnO improved the growth performance and gut microbiota of weaned piglets.

Summary: Due to the excessive use of antibiotics in agriculture, bacteria have developed resistance, leading to the global spread of Antibiotic Resistant Bacteria and causing hundreds of thousands of deaths. This paper proposes the use of zinc oxide nanoparticles synthesized by a sol-gel technique as a potential solution against various types of bacteria, including Gram-negative, Gram-positive, and multidrug-resistant strains. The study determined the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), and found that the zinc oxide nanoparticles were effective against several bacteria strains, including Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus.

Summary: Disseminated fusariosis is treated with amphotericin B and voriconazole, and determining antimicrobial resistance is important for adequate therapy. This study used MALDI-TOF MS to determine the minimal profile change concentration (MPCC) of 13 clinical isolates of Fusarium spp. The results showed that MALDI-TOF MS is a promising tool for determining MPCCs, but further statistical analyses are needed. This study contributes to the understanding of antimicrobial resistance mechanisms.

Summary: Zinc oxide (ZnO) supplementation at pharmacological doses is widely used in post-weaning piglets to manage post-weaning diarrhea (PWD), which causes significant economic losses in the most crucial phase of a piglet's production cycle. ZnO exerts various positive effects throughout the gastrointestinal tract through multiple mechanisms, targeting intestinal structure, digestion, antioxidants, and immunity. However, concerns over environmental impact and emerging threats are challenging the sustainability of ZnO's extensive utilization.

Summary: The use of titanium alloy Ti6Al4V implant prosthetics can lead to the release of harmful metal ions and bacterial infections in the human body. However, the introduction of a graphene oxide/zinc oxide/polydopamine nanocomposite coating has shown excellent antibacterial properties and wettability, as well as enhancing mineralization and corrosion resistance.

Summary: This study investigated the impact of zinc oxide and zinc oxide nanoparticles on Escherichia coli. The results showed that extended zinc exposure led to bacterial resistance to multiple antibiotics and impaired growth under elevated temperatures. Withdrawal of zinc reversed these effects, and zinc exposure caused significant changes in cell transcripts and proteins.

Summary: This study investigated the effects of nano zinc oxide and chelated zinc as alternatives to medical zinc oxide on weaned piglets. The results showed that pigs fed with nano zinc oxide and the positive control group had better growth performance compared to the chelated zinc treatment groups. Additionally, nano zinc oxide had significant effects on nutrient digestibility and fecal Lactobacillus concentrations.

Summary: Recently, there has been a lot of interest in using fluoropolymers as oxidative binders and modifiers in Al-based metastable intermixed composites (MICs) due to their high heat of reaction and gas production characteristics. This study incorporated Polytetrafluoroethylene (PTFE) and Polyvinylidene Fluoride (PVDF) into three typical Al-based MICs independently using different oxidizers. The experimental results showed that the addition of fluoropolymers significantly improved combustion heat, reduced the onset temperature of exothermic reaction, increased maximum pressure and pressurization rate, and decreased burn rates under confinement. The combustion products also exhibited smaller and more uniform particles.

Summary: Microplastic (MP) biofilms in landfill environment are hotspots of antibiotic resistance genes (ARGs), which are influenced by heavy metals and metallic nanoparticles (NPs) known as selective agents of ARGs. This study comparatively analyzed the effects of zinc oxide (ZnO) NPs and zinc ion (Zn2+) pressures on ARG abundances in MP biofilms and corresponding leachate. The presence of ZnO NPs and Zn2+ enhanced the enrichment of ARGs in MP biofilms, with ZnO NPs having a more pronounced effect. ZnO NPs and Zn2+ mainly decreased the abundances of ARGs in leachate.

Summary: This study presents an innovative method for fabricating inkjet-printed tracks using Zn nanoparticle ink and low-temperature in situ chemical sintering of curing ink. Chemical curing allows for the use of flexible substrates that cannot withstand traditional high thermal budgets. A specific acid concentration in the curing ink is found to be crucial in determining the electrical properties of the printed Zn nanoparticles, resulting in highly conductive and mechanically flexible features. Additionally, a touch sensor circuit utilizing all-Zn printed conductive tracks is demonstrated.
