The morphology and microstructure of the PSS-rGO/PANI nanocomposites were characterized using Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM).

Template-free synthesis of a multilayer manganese oxide/graphene oxide nanoflake-modified carbon felt as an anode material for microbial fuel cells.

A novel multilayer nanoflake structure of manganese oxide/graphene oxide (γ-MnO/GO) was fabricated a simple template-free chemical precipitation method, and the modified carbon felt (CF) electrode with γ-MnO/GO composite was used as an anode material for microbial fuel cells (MFCs). The characterization results revealed that the γ-MnO/GO composite has a novel multilayer nanoflake structure and offers a large specific surface area for bacterial adhesion. The electrochemical analyses demonstrated that the γ-MnO/GO composite exhibited excellent electrocatalytic activity and enhanced the electrochemical reaction rate and reduced the electron transfer resistance, consequently facilitating extracellular electron transfer (EET) between the anode and bacteria.

A versatile reactive layer toward ultra-long lifespan lithium metal anodes.

Unstable anode/electrolyte interfaces have significantly hindered the development of lithium (Li) metal batteries under high rates and large capacities. In this study, a versatile reactive layer based on sulfur-selenium crosslinked polyacrylonitrile brushes has been developed by a combined strategy of polymer topology design and chemical crosslinking. The sulfur-selenium crosslinked polyacrylonitrile side-chains can react with Li to generate passivated LiS-LiSe-containing solid electrolyte interphase while 3D lithiophilic porous nanonetworks enable Li penetration, contributing to achieving rapid and uniform Li ion flux and a dendrite-free anode.

Conjugated phthalocyanine-based framework as artificial SEI for over 400 Wh kg lithium-metal battery.

High-voltage lithium-metal batteries (HVLMBs) are appealing candidates for next-generation high-energy rechargeable batteries, but their practical applications are still limited by the severe capacity degradation, attributed to the poor interfacial stability and compatibility between the electrode and the electrolyte. In this work, a 2D conjugated phthalocyanine framework (CPF) containing single atoms (SAs) of cobalt (CoSAs-CPF) is developed as a novel artificial solid-electrolyte interphase (SEI) in which a large amount of charge is transferred to the CPF skeleton due to the Lewis acid activity of the Co metal sites and the strong electron-absorbing property of the cyano group (-CN), greatly enhancing the adsorption of the Li and regulating the Li distribution toward dendrite-free LMBs, which are superior to most of the reported SEI membranes. As a result, the Li||Li symmetrical cell with CoSAs-CPF-modified Li anodes (CoSAs-CPF@Li) exhibits a low polarization with an area capacity of 1.

Gas-propelled anti-hair follicle aging microneedle patch for the treatment of androgenetic alopecia.

Existing treatments for androgenetic alopecia (AGA) are unsatisfactory, owing to the two major reasons: (1) Oxidative stress and vascularization deficiency in the perifollicular environment provoke the premature senescence of hair follicles, limiting transformation from the telogen to the anagen phase; (2) The amount of drug delivered to the perifollicular region located in the deep dermis is very limited for passive drug delivery systems. Herein, we developed a gas-propelledmicroneedle patch integrated with ferrum-chelated puerarin/quercetin nanoparticles (PQFN) to increase drug accumulation in hair follicles and reshape the perifollicular environment for improved hair-regenerating effects. PQFN can rejuvenate testosterone (Tes)-induced senescence of dermal papilla cells by scavenging ROS, restoring mitochondrial function, regulating signaling pathways related to hair regeneration, and upregulating hair growth-promoting genes.

Phase transformation of calcium sulfate at mineral-solution interface: An overlooked pathway for selective enrichment of cadmium.

The reactions at the mineral-solution interface govern whether heavy metals (HMs) ions are retained within minerals or migrate with the solution, thus influencing their cycling and fate. However, the mechanisms driving this differential behavior of HMs at the interface remain poorly understood. In this study, we present a novel paradigm for the selective retention of HMs ions at the mineral-solution interface.

The overestimated risks for imported waste paper: Based on grey interval multi-criteria decision making under uncertainties.

China has prohibited the imported waste paper (IWP) from 2021 due to environmental burdens, its reasonability was doubtful owing to lacking a comprehensive evaluation. Previous studies just assessed the potential risks caused by pollutants from the upstream processes, ignoring the actual risks from the actual production processes, especially the generated toxic pollutants (heavy metals, PCDD/Fs, PAEs and DL-PCBs). Herein, ITOPSIS-IVIKOR-GRA incorporating distance and correlation by combining grey distance, grey group utility and individual regret, was developed to prioritize the risks of four typical recycled paper production by taking potential/actual health and ecological risks as criteria.
