Summary: This paper compares the energy requirements, CO2 emissions, and commodity prices of alternative plasma-activated ammonia synthesis with the conventional Haber-Bosch process. Economic positive externalities are evaluated for renewable energy-powered modular ammonia production, with a 6-fold improvement in plasma process efficiency projected to make it competitive. Technological prospects for achieving the thresholds are discussed, including advancements in plasma-catalyst synergy and direct reactions of N-2 with plasma-activated water.

Summary: This study evaluated the efficacy of cold plasma-activated bubbles in treating algal-impacted waters. The results showed that both air and oxygen-activated bubbles were effective in reducing cell numbers and increasing cell damage and inactivation. However, oxygen-activated bubbles were preferred due to lower nitrite and nitrate concentrations in the treated water. The study also found that different reactive species had varying impacts on algal cell removal and damage.

Summary: We introduce a versatile drug-loaded composite hydrogel that can simultaneously deliver a drug and CAP-generated molecules in a tissue target when activated by an argon-based cold atmospheric plasma jet. We demonstrated this concept by encapsulating gentamicin in sodium polyacrylate particles dispersed within a poly(vinyl alcohol) hydrogel matrix. The resulting gentamicin-PAA-PVA composite hydrogel can release gentamicin and effectively eradicate bacteria, including those in planktonic state and biofilm, when activated by CAP. The concept of the composite hydrogel can also be applied to other antimicrobial agents like cetrimide and silver, and activated by any dielectric barrier discharge CAP device.

Summary: Skin diseases can be categorized into infectious diseases, non-infectious inflammatory diseases, cancers, and wounds. The underlying causes include microbial infections, autoimmune responses, abnormal cellular proliferation or differentiation, and excessive production of inflammatory factors. Cold atmospheric plasma (CAP), as an innovative and non-invasive therapeutic approach, has shown promising efficacy in dermatology by inhibiting infections, promoting wound healing, suppressing cancer growth, and improving psoriasis or vitiligo lesions. This review summarizes recent advances in CAP therapies for various skin diseases and proposes future strategies for increasing effectiveness and expanding clinical indications.

Summary: In this study, the authors investigated the inactivation effect of cold atmospheric plasma (CAP) combined with plasma-activated water (PAW) treatment on two types of fungi. The results showed that the combination of short-term CAP treatment and long-term PAW treatment significantly reduced the fungi compared to the single CAP approach. Comparative analysis revealed that different reactive oxygen and nitrogen species played a role in the inactivation of fungi during the combination treatment. The synergistic effect was attributed to the increasing intracellular reactive species-induced damage to the fungal membrane and mitochondria. This study provides new insights into the optimal application of low-temperature plasma technology in fungal disinfection.

Summary: A novel approach using cold atmospheric-pressure plasma (CAP) and plasma-activated water (PAW) was employed to efficiently remove aflatoxin B-1 (AFB(1)), a highly toxic metabolite from Aspergillus flavus (A. flavus). CAP could effectively degrade AFB(1), while PAW produced by CAP further removed AFB(1) with longer treatment time. The dominant reactive species involved in the degradation process were hydroxyl radical (center dot OH) in CAP treatment and singlet oxygen (O-1(2)) in PAW treatment.

Summary: Cold atmospheric pressure plasma jets are used in agriculture to treat seeds and plants, but they can have side effects due to the reactive oxygen and nitrogen species generated. Research shows that using plasma treatment on seeds can accelerate seed imbibition, germination, and radicle growing rates, while also modifying seed surface properties. Plasma treatment creates pores, surface defects, and corrugation on seed coats, leading to improved wetting properties and accelerated water uptake. Plasma lamps, which generate high frequency electromagnetic fields and photons, can be used for agricultural purposes without the side effects of plasma jets.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
