A Unified Polymer Hydrogel Electrolyte Integrating Robust Adhesion, Self‐Healing, and Oxygen Permeability in Flexible Neutral Zn‐Air Batteries

Advanced Materials, EarlyView.
Flexible neutral Zn‐air batteries achieving a remarkable 3000‐cycle lifespan and withstanding 1000 bending cycles are reported. This performance is realized by employing a 3D physically cross‐linked neutral hydrogel electrolyte that integrates high adhesion, self‐healing, O2 permeability, and CO2 tolerance to resolve critical stability challenges ...

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Evaluation of Sun Protection Factor (SPF) and Protection Factor of UVA (PFA) of the Sunscreen Containing Microalgal Extracts and MAAs

, 2014
천연물 유래 자외선차단제 개발을 위해 미세조류 추출물 및 mycosporine-like amino acids(MAAs)의 활용가능성을 연구하였다. Chlamycomonas hedleyi 추출물과 추출물 분획물인 MAAs가 각각 7% 포함된 자외선차단크림을 제조하고 인체 적용시험을 실시하였다. 이를 통하여 자외선차단지수(SPF) 및 자외선 A차단지수(PFA)를 평가하였다. Ch. hedleyi 추출물과 MAAs 함유 자외선 차단 크림의 자외선 차단지수는
