Summary: In this study, carbon particles were adsorbed on the surface of stainless steel meshes (SSMs) to form a thin hydrophobic coating, and a rough structure was then constructed through chemical vapor deposition and high temperature calcination, with the resultant SSM surface wrapped with uniform silica coating possessing superoleophobicity-underwater. The prepared SSMs exhibited superhydrophilicity in air and superoleophobicity-underwater. They showed high separation efficiency (above 98.8%) and separation flux (46,300 L·m(-2)·h(-1)) for oil/water mixtures. Immersion in different solutions did not significantly affect their separation efficiency (above 97.3%), and further immersion in dopamine and octadecylamine solutions transformed the SSMs into superhydrophobic SSMs with reverse surface wettability, which also exhibited good separation efficiency and separation flux for oil/water separation.

Summary: In this study, aerogels were prepared using cellulose and starch as primary materials, with the addition of N,N'-methylenebisacrylamide (MBA) as a cross-linking agent. The proportions of cellulose, starch, and MBA significantly influenced the chemical, morphological, and textural characteristics of the aerogels. The study found that increasing the proportion of cellulose resulted in stronger adsorption forces and larger pores within the aerogel structure. When the mass fractions of starch and cellulose were 5 wt% and 1 wt% respectively, the aerogels exhibited the smallest pore size and largest porosity. The addition of 3 wt% of MBA resulted in the best internal structure of the aerogel. The study also showed that MBA improved the water absorption, expansion characteristics, and dye adsorption properties of the aerogel. Furthermore, the aerogels demonstrated a higher capacity for incorporating vitamin E compared to native starch.

Summary: A novel N-doped porous carbon network (SC-CuSA-NC) catalyst with Cu single atoms is constructed via flash nanocomplexation (FNC) technology and a double-network gel-limiting strategy. SC-CuSA-NC shows superior ORR/OER/ HER performance due to the highly active Cu-N4 sites and distinct interconnected three-dimensional porous carbon network. The ZAB assembled by SC-CuSA-NC displays a high specific capacity (775.0 mAh g-1) and could effectively drive water splitting (1.58 V at 10 mA cm-2). This work expands the synthesis method of single-atom catalysts and provides a new approach for the accurate and controllable synthesis of electro- catalysts for water splitting and ZABs.

Summary: A novel enzyme-responsive fluorescent nanopesticide was developed using a continuous nanoprecipitation method. The nanopesticide demonstrated good water dispersibility, storage stability, and enhanced wettability compared to commercial formulations. The controlled release of pesticides was achieved through protein degradation caused by trypsin. By tracking fluorescence, the deposition, distribution, and transport of the nanopesticide on target plants were accurately monitored. Furthermore, the nanopesticide showed high control efficacy against Plutella xylostella L. and has promising potential in sustainable plant protection due to its eco-friendly composition and absence of organic solvent.

Summary: In this study, a beta-cyclodextrin-grafted polyethylenimine (beta-CD-PEI) was prepared and further coupled with folic acid to form a nanocarrier (beta-CD-PEI-FA) for miR-34a-5p delivery. The nanocomplex beta-CD-PEI-FA/miR-34a-5p effectively protected miR-34a-5p from degradation and exhibited suitable size and potential for endocytosis. The nanocarrier not only inhibited the proliferation of KSHV-infected cells but also reduced the expression levels of KSHV genes, suggesting its potential as an antiviral drug delivery system for anti-KSHV therapy.

Summary: To improve the stability of flexible supercapacitors, a covalent modification strategy was employed to create stable electrodes. Graphitized carbon cloth (GCC) and reduced graphene oxide (rGO) were covalently bonded together with the polymerization of aniline (PANI) through Suzuki reaction. The resulting GCC-PANI-rGO electrode demonstrated stable electrochemical performance, retaining 97.73% of its initial specific capacitance after 15,000 charge-discharge cycles at 40 mA/cm2. The asymmetric flexible solid supercapacitor (FSSC) prepared using GCC-PANI-rGO and GCC showed a capacitance retention of 108.78% after 10,000 mechanical folding cycles. Additionally, the electrode exhibited a pi-pi conjugation system, low charge transfer resistance (0.428 ohm), and high specific capacitance and energy density of 11.825 F/cm2 and 1.642 mWh/cm2 at 1 mA/cm2, respectively. The energy density of the FSSC reached 0.266 mWh/cm2 at 1 mA/cm2, surpassing most FSSCs based on PANI and graphene. This work provides an essential covalently synthetic strategy for flexible supercapacitors with stable electrochemical performance in practical applications.
