A physical unclonable function (PUF) is a foundation of anti-counterfeiting processes due to its inherent uniqueness. However, the self-limitation conventional graphical/spectral PUFs in materials often makes it difficult have both high code flexibility and environmental stability practice. In this study, we propose universal, fractal-guided film annealing strategy realize random Au network-based that can be designed on demand complexity, enabling tags' intrinsic uniqueness stability....
The NaOH/γ-Al2O3 as catalyst for the synthesis of glycerol carbonate via transesterification with dimethyl (DMC) has been developed in this work. It was found that a highly efficient heterogeneous and can be easily recovered recycled. Under conditions DMC/glycerol molar ratio 2, catalyst/glycerol weight 3%, reaction time 1 h, temperature 78 °C, conversion selectivity to reached 97.9% 99.0%, respectively. catalytic performance 80 wt.% is much better than K2CO3. A plausible mechanism about...
Abstract Flexible organic solar cells (OSCs) are very promising for use in portable power supply devices due to the advantages of low‐cost, light‐weight, and flexibility. However, efficiencies flexible OSCs limited by transparent electrodes owing their nonoptimal electrical, optical, mechanical properties. To address these challenges, leaf‐like biomimetic proposed achieve an efficient light capture glossy surface a high‐efficiency OSC. mimic internal anatomy leaf, conformable electrode stack...
The visual aesthetic that involves color, brightness, and glossiness is of great importance for building integrated photovoltaics. Semitransparent organic solar cells (ST-OSCs) are thus considered as the most promising candidate due to their superiority in transparency efficiency. However, realization high color purity with narrow bandpass transmitted light usually causes severely suppressed ST-OSCs. Herein, we present a spectrally selective electrode (SSE) by imitating integrating strategy...
Background/Objectives: Platycodon grandiflorus (PG) has been widely researched as a conductant drug for the treatment of lung diseases by ancient and modern traditional Chinese medicine (TCM) practitioners. Inspired mechanism our previous finding about fructans fructooligosaccharides from (FFPG), we developed nano delivery system (NDDS) targeting cancer. The aim was to improve efficiency liposomal Paclitaxel (PTX) enhance anti-tumor efficacy. Methods: FFPG-Lip-PTX NDDS prepared electrostatic...
The number of excellent 2D materials is finite for nano optoelectric devices including transistors, diodes, sensors, and so forth, thus the modulation important to improve performance current eligible materials, even transform unqualified into materials.
