Despite the skin microbiome has been linked to skin health and diseases,its role in modulating human skin appearance remains *** a total of 1244 face imaging phenomes and 246 cheek metagenomes,we first established three skin age indices by machine learning,including skin phenotype age(SPA),skin microbiota age(SMA),and skin integration age(SIA)as surrogates of phenotypic aging,microbial aging,and their combination,***,we found that besides aging and gender as intrinsic factors,skin microbiome might also play a role in shaping skin imaging phenotypes(SIPs).Skin taxonomic and functionalαdiversity was positively linked to melanin,pore,pigment,and ultraviolet spot levels,but negatively linked to sebum,lightening,and porphyrin ***,certain species were correlated with specific SIPs,such as sebum and lightening levels negatively correlated with Corynebacterium matruchotii,Staphylococcus capitis,and Streptococcus ***,we demonstrated skin microbial potential in predicting SIPs,among which the lightening level presented the least error of 1.8%.Lastly,we provided a reservoir of potential mechanisms through which skin microbiome adjusted the SIPs,including the modulation of pore,wrinkle,and sebum levels by cobalamin and heme synthesis pathways,predominantly driven by Cutibacterium *** pioneering study unveils the paradigm for the hidden links between skin microbiome and skin imaging phenome,providing novel insights into how skin microbiome shapes skin appearance and its healthy aging.

This study investigates the thermo-mechanical properties of graphene nanoplatelet (GNP)-filled recycled polypropylene (rPP) nanocomposites to enhance their performance and sustainability. It examines the influence of GNP loading on mechanical, thermal, and electrical behavior, focusing on tensile strength, Young's modulus, impact strength, heat deflection temperature, thermal conductivity, and electrical resistivity. The GNP-rPP composites are fabricated by functionalizing GNPs through mild acid treatment to enhance compatibility with the rPP matrix, followed by melt mixing in a twin-screw extruder at varying GNP loadings (0–20 Phr). The tensile strength, Young's modulus, and flexural strength of recycled polypropylene increased by 15.6 MPa, 3.7 MPa, and 2.41 MPa, respectively, as the GNP loading increased from 0 to 20 Phr. Adding Adding GNP up to 20 Phr into the rPP matrix also increased the crystallization, melting, onset, and maximum decomposition temperatures by 5, 4.7, 8.36, and 7.02 °C, respectively. Additionally, the thermal conductivity shows an increasing trend, with an improvement of 221 mW/mK. However, including fillers reduced electrical resistivity by 105 Ω cm and impact strength by 64.27 Jm⁻1. The significance of this work lies in providing eco-friendly alternatives to conventional polymers, promoting the adoption of recycled materials, and contributing to sustainable product design. The outcomes offer valuable insights for industries promoting a circular economy with cleaner production while reducing the carbon footprint. Also, the recycling and reuse of synthetic polymers uncover a valuable prospect for tackling the escalating global polymeric waste problem. © 2025 The Authors

The exfoliation of bulk 2H-molybdenum disulfide(2H-MoS_(2))into few-layer nanosheets with 1T-phase and controlled layers represents a daunting challenge towards the device applications of MoS_(2).Conventional ion intercalation assisted exfoliation needs the use of hazardous n-butyllithium and/or elaborate control of the intercalation potential to avoid the decomposition of the MoS_(2).This work reports a facile strategy by intercalating Li ions electrochemically with ether-based electrolyte into the van der Waals(vdW)channels of MoS_(2),which successfully avoids the decomposition of MoS_(2)at low *** co-intercalation of Li+and the ether solvent into MoS_(2)makes a first-order phase transformation,forming a superlattice phase,which preserves the layered structure and hence enables the exfoliation of bulk 2H-MoS_(2)into bilayer nanosheets with *** with the pristine 2H-MoS_(2),the bilayer 1T-MoS_(2)nanosheets exhibit better electrocatalytic performance for the hydrogen evolution reaction(HER).This facile method should be easily extended to the exfoliation of various transition metal dichalcogenides(TMDs).
