This review introduces an innovative and integrative perspective on nanoemulsion technology by linking formulation parameters directly to cosmetic performance outcomes—a relationship that has been largely overlooked in previous studies. Unlike earlier reviews that provided only general overviews, this paper critically synthesizes experimental findings to establish how specific formulation choices, such as surfactant selection, oil phase composition, and preparation method, affect stability, penetration depth, and active ingredient release in cosmetic products.

The review also highlights emerging strategies for achieving safer, more sustainable nanoemulsions through the use of natural surfactants, biodegradable oils, and environmentally responsible production methods. By combining insights from material science, dermatology, and cosmetic engineering, it provides a scientific framework for optimizing nanoemulsion design and guiding future product development.

Ultimately, this work not only consolidates the current understanding of nanoemulsions in cosmetics but also sets the foundation for the next generation of high-performance, biocompatible, and eco-friendly skincare formulations—bridging the gap between scientific innovation and consumer demand.

Zn-I₂ batteries have emerged as promising next-generation energy storage systems owing to their inherent safety, environmental compatibility, rapid reaction kinetics, and small voltage hysteresis. Nevertheless, two critical challenges, i.e., zinc dendrite growth and polyiodide shuttle effect, severely impede their commercial viability. To conquer these limitations, this study develops a multifunctional separator fabricated from straw-derived carboxylated nanocellulose, with its negative charge density further reinforced by anionic polyacrylamide incorporation. This modification simultaneously improves the separator’s mechanical properties, ionic conductivity, and Zn²⁺ ion transfer number. Remarkably, despite its ultrathin 20 μm profile, the engineered separator demonstrates exceptional dendrite suppression and parasitic reaction inhibition, enabling Zn//Zn symmetric cells to achieve impressive cycle life (> 1800 h at 2 mA cm⁻²/2 mAh cm⁻²) while maintaining robust performance even at ultrahigh areal capacities (25 mAh cm⁻²). Additionally, the separator’s anionic characteristic effectively blocks polyiodide migration through electrostatic repulsion, yielding Zn-I₂ batteries with outstanding rate capability (120.7 mAh g⁻¹ at 5 A g⁻¹) and excellent cyclability (94.2% capacity retention after 10,000 cycles). And superior cycling stability can still be achieved under zinc-deficient condition and pouch cell configuration. This work establishes a new paradigm for designing high-performance zinc-based energy storage systems through rational separator engineering.

Researchers at Tohoku University used the Digital Hydrogen Platform - which combines data from over five thousand meticulously curated experimental records - as a tool to guide materials design for hydrogen storage.
